The aim was to identify risk factors for death following proximal femur fractures in elderly patients. Patients and methods: This was a prospective, observational, longitudinal study conducted over an 18-month period in the Orthopedics-Traumatology Department of Aristide Le Dantec Hospital in Dakar. We evaluated a total of 93 patients aged at least 60 years with a proximal femur fracture whose date of onset was less than 3 weeks. The identification of risk factors for death took into account socio-demographic, clinical and therapeutic parameters. Results: The number of patients who died was 19 (20.43%). There was no significant difference in mortality according to age, gender or residence. There was no association between admission time and mortality. The association between the number of comorbidities and mortality was significant. The association between mortality and ASA score and type of treatment was highly significant. Operating time had no influence on mortality. Type of anesthesia, on the other hand, did influence mortality. Conclusion: Mortality due to proximal femur fractures in the elderly remains high. In our practice, this mortality was related to the presence of comorbidity, impaired cognitive function, ASA score, type of treatment and type of anesthesia.展开更多

For children less than 5 years old, non-surgical approach is recommended. For pediatric patients 5 - 14 years old, the most common mode of treatment is flexible intramedullary nailing with a known complication of pain at post-op site, inflammatory reaction/bursitis at the entry site, superficial and deep infection, knee synovitis, knee stiffness, leg length discrepancy, proximal nail migration, angulation or malunion, delayed and non-union, implant breakage. This study aims to present a rare complication of a femoral fracture fixed with flexible intramedullary nail. Methodology: We report the outcome of a 12-year-old male with peri implant fracture of the left femur. He underwent removal of plates and screws and subsequently fixed with flexible intramedullary nails. Patient was followed up at 1, 3, 7, and 10 months post-operatively. Varus-valgus, sagittal angulation, and limb shortening were measured pre- and post-operatively. Complications were recorded on each visit. Results: Pre-operative varus angulation was 10˚, pro-curvatum of 55˚ with limb shortening of 4 cm. Postoperatively, varus was maintained to 10˚ but pro-curvatum was corrected to 4˚ and limb shortening was reduced to 1 cm. However, after 1 month the varus angulation increased to 30˚ while maintaining sagittal pro-curvatum. Limb shortening also increased to 2 cm. New bone formation started to appear along the mechanical axis of the left femur which is apparent at 3 months post-op and pro-curvatum increased to 20˚. At 7 and 10 months post-op no signs of union was noted at the fracture site but the callus formation along the mechanical axis gradually matured and appeared as a new femoral shaft. Conclusion: Formation of new bone in response to unstable flexible intramedullary fixation in pediatric femoral shaft fracture is a very rare complication.展开更多

With the increase of operation volume, its incidence is increasing year by year. The treatment of this fracture is affected by many factors, including fracture type, prosthesis stability, patient age and comorbidities, and individualized treatment strategy is needed. In recent years, the internal fixation technology and prosthetic revision technology have made significant progress in surgical treatment, such as locking steel plate, titanium cable and bridge combined internal fixation system and other new technologies have effectively improved the treatment effect. In addition, the application of new materials and 3D printing technology, as well as the optimization of multidisciplinary cooperation mode, also provide new ideas for the treatment of complex fractures. However, there are still some problems such as inaccurate diagnosis, difficult choice of treatment options and high incidence of postoperative complications. In the future, technological innovation, the introduction of artificial intelligence and big data, and the further development of personalized treatment will bring more possibilities to improve the prognosis and quality of life of patients. This study summarizes the relevant research results and prospects the future development direction, providing references for clinical practice and subsequent research.展开更多

However, an adequate osteosynthesis method has not been elucidated yet. This study investigated the displacement direction of the femoral head fragment and its effect on the bone using finite element method. A finite element model for CSFF was developed from CT image data of a patient with osteoporosis using Mechanical Finder (ver. 11). Subsequently, finite element analyses were performed on six osteosynthesis models under maximum load applied during walking. The compressive stresses, tensile stresses, and compressive strains of each model were examined. The results suggested that the compressive and tensile stress distributions were concentrated on the anterior side of the femoral neck. Compressive strain distribution in the femoral head and neck was concentrated in four areas: at the tip of the blade or lag screw, the anteroinferior side of the blade or lag screw near the fracture site, and the upper right and lower left near the junction of the blade or lag screw and nail. Thus, the distribution of both these stresses revealed that the femoral head fragment was prone to anterior and inferior displacement. Distribution of compressive strains revealed the direction of the stress exerted by the osteosynthetic implant on the bone. The same results were observed in all osteosynthetic implants;thus, the findings could lay the foundation for developing methods for placing osteosynthetic implants less prone to displacement and the osteosynthetic implants themselves. In particular, the study provides insight into the optimal treatment of CSFF.展开更多

Methods： According to the AO classification, all of 32 cases were classified as extra-articular type A. 32 cases were treated with interlocking intramedullary nail by closed insertion from intercondylar fossa of the knee. All cases accepted CPM exercise as early as possible after operation. Results： Following up 5 to 15 months, all fractures united within an average duration of 5.3 months （4-7 months）. According to the Shelbourne scale, the excellent rate of the knee function was 86.3%. Conclusion： Retrograde interlocking intramedullary nail is useful alternative implant for the treatment of osteoporotic supracondylar fracture of femur, particularly of the type A fracture in the elderly population. Its merits include stable fixation, high rate of fracture union and few complications.展开更多

However some studies evidenced that early surgery doesn’t always have a beneficial effect on mortality and complications. Therefore further studies could be useful in order to better assess risk related factors of patients requiring surgical treatment for femoral neck fracture. The purpose of this study is to evaluate the effect of preoperative ASA score and timing of surgery on mortality, complications and clinical outcome. Methods: All 336 patients operated in our center from January 2013 to December 2014 were selected for this retrospective study. Patients were divided in three groups as follows: group 1 patients treated within 48 hours;group 2 patients treated between 48 to 96 hours;group 3 patients treated over 96 hours. The preoperative ASA score was recorded for each patient. Complication, clinical outcome and mortality at one-year follow-up were evaluated. At follow-up ambulation was graded as: confined to bed, assisted ambulation, and normal ambulation. Complications both local (infections, malunion, dislocation) and systemic (deep vein thrombosis, pulmonary embolism, lung infections, ischemic disorders of heart) were recorded as well as number of transfusions. Statistical analysis was performed with chi square test and P value Results: 308 patients’ data were fully available for this study. At one-year follow-up return to normal ambulation was higher for patients of group 1 as compared with group 2 and 3 and in group 2 as compared with group 3 (P = 0.04). There was no difference in mortality and return to ambulation between patients with ASA score 1 and 2 (P = 0.06);patients with ASA score ≥ 3 showed a statistically significant higher mortality (P = 0.004) and rate of complications (0.0008) regardless of timing of surgery. There was no statistically significance in blood transfusion among the three groups. Discussion and Conclusion: Clinical outcome, complications and mortality have been previously reported from many authors and most studies agreed that early surgical treatment is recommended regardless of age and preoperative status of the patient. The present study suggests that early surgical treatment is actually able to reduce mortality and complications and to improve clinical outcome in patients with better preoperative conditions, while for patients with ASA score ≥ 3 treatment within 48 hours seems not to prevent mortality and complications and improve clinical outcome.展开更多

Methods: Forty-three patients who had a fracture of the femoral shaft were managed between 2005 and 2008 with intramedullary nailing and the use of only one screw for distal interlocking. Prospectively we evaluated the union time, possible reoperation, fixation and fracture alignment, range of knee motion and complications. Results: Union occurred within a mean duration of 18.7 weeks. No failures of the fixation and fracture alignment and no more than 1 cm shortness were detected. The knee range of motion was all more than 90 degree. Only one deep venous thrombosis was detected as complication. Conclusions: Compressive nailing using proximal hole and only distal dynamic hole with one screw is a convenient technique for femur fractures.展开更多

文摘Introduction: Proximal femur fractures are traumatic injuries involving the neck and trochanteric region of the femur. The aim was to identify risk factors for death following proximal femur fractures in elderly patients. Patients and methods: This was a prospective, observational, longitudinal study conducted over an 18-month period in the Orthopedics-Traumatology Department of Aristide Le Dantec Hospital in Dakar. We evaluated a total of 93 patients aged at least 60 years with a proximal femur fracture whose date of onset was less than 3 weeks. The identification of risk factors for death took into account socio-demographic, clinical and therapeutic parameters. Results: The number of patients who died was 19 (20.43%). There was no significant difference in mortality according to age, gender or residence. There was no association between admission time and mortality. The association between the number of comorbidities and mortality was significant. The association between mortality and ASA score and type of treatment was highly significant. Operating time had no influence on mortality. Type of anesthesia, on the other hand, did influence mortality. Conclusion: Mortality due to proximal femur fractures in the elderly remains high. In our practice, this mortality was related to the presence of comorbidity, impaired cognitive function, ASA score, type of treatment and type of anesthesia.

文摘Background of the Study: Femoral shaft fracture is the most common pediatric injury requiring hospitalization. For children less than 5 years old, non-surgical approach is recommended. For pediatric patients 5 - 14 years old, the most common mode of treatment is flexible intramedullary nailing with a known complication of pain at post-op site, inflammatory reaction/bursitis at the entry site, superficial and deep infection, knee synovitis, knee stiffness, leg length discrepancy, proximal nail migration, angulation or malunion, delayed and non-union, implant breakage. This study aims to present a rare complication of a femoral fracture fixed with flexible intramedullary nail. Methodology: We report the outcome of a 12-year-old male with peri implant fracture of the left femur. He underwent removal of plates and screws and subsequently fixed with flexible intramedullary nails. Patient was followed up at 1, 3, 7, and 10 months post-operatively. Varus-valgus, sagittal angulation, and limb shortening were measured pre- and post-operatively. Complications were recorded on each visit. Results: Pre-operative varus angulation was 10˚, pro-curvatum of 55˚ with limb shortening of 4 cm. Postoperatively, varus was maintained to 10˚ but pro-curvatum was corrected to 4˚ and limb shortening was reduced to 1 cm. However, after 1 month the varus angulation increased to 30˚ while maintaining sagittal pro-curvatum. Limb shortening also increased to 2 cm. New bone formation started to appear along the mechanical axis of the left femur which is apparent at 3 months post-op and pro-curvatum increased to 20˚. At 7 and 10 months post-op no signs of union was noted at the fracture site but the callus formation along the mechanical axis gradually matured and appeared as a new femoral shaft. Conclusion: Formation of new bone in response to unstable flexible intramedullary fixation in pediatric femoral shaft fracture is a very rare complication.
文摘Periprosthetic fracture of femur is a common and complex complication after joint replacement. With the increase of operation volume, its incidence is increasing year by year. The treatment of this fracture is affected by many factors, including fracture type, prosthesis stability, patient age and comorbidities, and individualized treatment strategy is needed. In recent years, the internal fixation technology and prosthetic revision technology have made significant progress in surgical treatment, such as locking steel plate, titanium cable and bridge combined internal fixation system and other new technologies have effectively improved the treatment effect. In addition, the application of new materials and 3D printing technology, as well as the optimization of multidisciplinary cooperation mode, also provide new ideas for the treatment of complex fractures. However, there are still some problems such as inaccurate diagnosis, difficult choice of treatment options and high incidence of postoperative complications. In the future, technological innovation, the introduction of artificial intelligence and big data, and the further development of personalized treatment will bring more possibilities to improve the prognosis and quality of life of patients. This study summarizes the relevant research results and prospects the future development direction, providing references for clinical practice and subsequent research.
文摘Fractures of femur proximal extremity(FFPE)are the most common fragility fractures requiring hospitalization,with a high risk of mortality,low independence in the activities of daily living and severe consequences on healthrelated quality of life.Timing for surgery has a key role in the management of elderly patients with FFPE as recommended by the Australian and New Zealand guidelines and the National Institute for Health and Care Excellence guidelines.Early surgery(within 48 h from hospital admission)allows significant benefits in terms of lower rates of postoperative complications and risk of death and can provide better functional outcomes.Therefore,time for surgery could be considered as a comorbidity marker.The choice between conservative or surgical approach surprisingly seems to be still not strongly supported by available literature,but it seems that both 30 d and 1 year risk of mortality is higher with the conservative treatment rather than with surgery.In light of these considerations,the optimization of FFPE management care is mandatory to improve functional outcomes and to reduce sanitary costs.Albeit it is widely accepted that transdisciplinary approach to patients suffering from FFPE is mandatory to optimize both short-term and long-term outcomes,the feasibility of a comprehensive approach in clinical practice is still a challenge.In particular,the large variability of figures involved could be considered both a resource and an additional disadvantage taking into account the difficulty to coordinate multidisciplinary approach covering care in all settings.Therefore,the aim of the present article was to summarize current evidence supporting transdisciplinary management of patients with FFPE,highlighting the benefits,feasibility and limitations of this approach.
文摘Purpose:Distal femoral fracture is one of the most common lower limb injuries and accounts for less than 1%of all fractures.Open fracture takes 5%-10%of the all distal femoral fractures,which is at an increased risk of complications.There were limited studies which documented the outcomes of such cases.The present study aims to evaluate the outcome and complications in these fractures using primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to aggressive debridement.Methods:This is a prospective study conducted in a tertiary care orthopaedic hospital in northern India.Thirty patients of open distal femoral fractures were managed by primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to aggressive debridement.They were followed for minimum of six months.Patients were followed up monthly for first four months,at six months and one year after surgery.Clinical and radiological signs of healing,any complications,time to union,and functional outcome were assessed.Results:The mean age of patients was 44.33 years(range 20-82 years)with male predominance of 66.7%.According to Gustilo-Anderson classification,there were 5,15 and 10 patients with open grade I,II and IIIA distal femoral fractures respectively.According to orthopaedic trauma association(OTA)classification,majority of patients in our study were of C3 type.The mean time to bony union was 5.6 months(range 4-9 months).Average postoperative knee range of motion(ROM)at the latest follow-up was 98°(range 70°-120°).Lysholm knee scoring scale showed excellent score in 11 patients,good in 9 patients,fair and poor in 5 patients each;however,there was no significant correlation with fracture pattern types(p<0.05).Knee stiffness was the major complications encountered in the study.The knee ROM was<90°in 5 patients and 90°-120°in rest of the patients,while 1 patient had extensor lag of 10°.One patient had implant failure and lost to follow-up;3 patients had deep infection.Conclusion:An approach of primary definitive fixation with condylar locking plate and antibiotic impregnated collagen sheet secondary to early aggressive debridement in open distal femur fractures shows significant results in terms of functional and radiological outcomes with minimal complications.
文摘BACKGROUND Surgical treatment of complex fractures of the distal femur in the elderly is controversial.Osteoporosis and pre-existent osteoarthritis are common comorbidities in the elderly which add to the need for early walking and rapid restoration of function and also pose significant obstacles to achievement of satisfactory results with standard fixation techniques.Recently,several authors have suggested that primary arthroplasty could be a viable alternative option to standard fixation techniques in selected patients with complex distal femur fractures.AIM To present our experience with 11 cases of distal femur fractures treated with knee arthroplasty and large femoral resection in a population of patients over the age of 85.METHODS Data from 11 consecutive patients(10 females,1 male)presenting with acute intra-articular supracondylar or intercondylar distal femur fractures and with pre-existent primary osteoarthritis who were treated with primary knee arthroplasty were recorded.We collected standard demographic data,comorbidities and patient reported outcomes including Visual Analogical Scale(VAS),Oxford Knee Score(OKS)and Barthel’s Index.Post-operative joint range of motion(ROM)and standard radiographic data were also collected.RESULTS At a mean follow-up of 23.2 mo,all of the implants were well-positioned and osteointegrated.Furthermore,all the patients were alive and walking either independently or with walking aids.There was a marked improvement in pain(VAS 4.5 postop vs 1.9 at the last follow-up),OKS score(29.5 postop vs 36.81 at the last follow-up),ROM(96.2°postop vs 102°at the last follow-up)and restoration of pre-injury ambulatory status(average Barthel Index 77.3).The radiographic evaluations showed good restoration of the articular geometry.No deaths and no complications were recorded.CONCLUSION In conclusion,we believe that knee megaprosthesis in the case of complex fractures of the distal femur is a valid surgical choice.This is particularly true in elderly patients with severe osteoporosis and pre-existing osteoarthritis.It is important to note that this surgery should be performed by surgeons with proven experience in prosthetic hip and knee surgery and that a scrupulous selection of the cases is completed.
文摘In this editorial,I present my comments on the article by Solarino et al.Conversion hip arthroplasty,which is an optional salvage procedure performed following unsuccessful fixation of intertrochanteric femur fractures in elderly pati-ents,entails more complex processes and higher rates of operative complications than primary arthroplasty.Hence,it is important to consider the appropriateness of the primary treatment choice,as well as the adequacy of nailing fixation for intertrochanteric fractures.This article briefly analyzes the possible factors contributing to the nailing failure of intertrochanteric fractures and attempts to find corresponding countermeasures to prevent fixation failures.It also analyzes the choice of treatment between nailing fixation and primary arthroplasty for intertrochanteric fractures.
文摘Introduction: Traumatic hip dislocation associated with femur fracture is a rare and complex injury that occurs in the context of multiple trauma. Public road accidents represent more than 64% of the circumstances (automobiles 46% and two-wheelers 18%). Objective: Report a rare case of injury association and the speed of treatment (less than 6 hours). Clinical case: 26-year-old patient, victim of a road traffic accident. Admitted to the emergency room one hour after the trauma in a context of severe pain and absolute functional impotence of both pelvic limbs. Clinical examination reveals closed trauma to both pelvic limbs, with deformation of the right thigh, a vicious attitude of the contralateral lower limb in adduction, shortening and medial rotation. Conclusion: This is a rare injury association, which benefited from treatment within less than 6 hours.
文摘Coronal shear fractures of the femoral neck (CSFF) are the most challenging to treat among proximal femur fractures, directly affecting the life expectancy of patients with osteoporosis. However, an adequate osteosynthesis method has not been elucidated yet. This study investigated the displacement direction of the femoral head fragment and its effect on the bone using finite element method. A finite element model for CSFF was developed from CT image data of a patient with osteoporosis using Mechanical Finder (ver. 11). Subsequently, finite element analyses were performed on six osteosynthesis models under maximum load applied during walking. The compressive stresses, tensile stresses, and compressive strains of each model were examined. The results suggested that the compressive and tensile stress distributions were concentrated on the anterior side of the femoral neck. Compressive strain distribution in the femoral head and neck was concentrated in four areas: at the tip of the blade or lag screw, the anteroinferior side of the blade or lag screw near the fracture site, and the upper right and lower left near the junction of the blade or lag screw and nail. Thus, the distribution of both these stresses revealed that the femoral head fragment was prone to anterior and inferior displacement. Distribution of compressive strains revealed the direction of the stress exerted by the osteosynthetic implant on the bone. The same results were observed in all osteosynthetic implants;thus, the findings could lay the foundation for developing methods for placing osteosynthetic implants less prone to displacement and the osteosynthetic implants themselves. In particular, the study provides insight into the optimal treatment of CSFF.
文摘We present a detailed outline of treatment of intertrochanteric fractures of femur with a new technique on the basis of principles of combined traditional chinese and western medicine. We use pins and an outer fixation frame, which keeps the injured limb in abduction and under traction and at the same time allows for functional exercise of all the joints in the extremity. The procedure is discussed and compared with other different techniques.
文摘BACKGROUND Spontaneous bilateral femur neck fracture is a rare entity in the general population.CASE SUMMARY A 17-year-old immobile,developmentally delayed male with the sequelae of cerebral palsy fractured both femoral necks during a grand mal epileptic seizure.He had been treated with valproic acid as an antiseizure medication for about 10years;otherwise,he had no history of drug use.The laboratory analysis was normal except a marked vitamin D deficiency.Closed reduction and osteosynthesis with percutaneous cannulated screws were performed.Solid union was observed at 6 mo,and rapid postoperative rehabilitation was started.CONCLUSION A femoral neck fracture may occur in a person with epilepsy presenting with hip pain in the emergency department.
文摘Objective： To report 32 cases of femur supracondylar fracture treated with retrograde interlocking intramedullary nails in elderly patients. Methods： According to the AO classification, all of 32 cases were classified as extra-articular type A. 32 cases were treated with interlocking intramedullary nail by closed insertion from intercondylar fossa of the knee. All cases accepted CPM exercise as early as possible after operation. Results： Following up 5 to 15 months, all fractures united within an average duration of 5.3 months （4-7 months）. According to the Shelbourne scale, the excellent rate of the knee function was 86.3%. Conclusion： Retrograde interlocking intramedullary nail is useful alternative implant for the treatment of osteoporotic supracondylar fracture of femur, particularly of the type A fracture in the elderly population. Its merits include stable fixation, high rate of fracture union and few complications.
文摘BACKGROUND The National Institute for Health and Care Excellence(NICE)guidelines have advised further research is required into investigating the added prognostic value of bone mineral density(BMD)in the assessment of fracture risk with the Fracture Risk Assessment Tool(FRAX)score.AIM To investigate the significance of BMD in fracture neck of femur patients and compare it to the outcome of the FRAX score.METHODS Inclusion criteria for this study were all patients who underwent dual-energy Xray absorptiometry(DXA)scan following fracture neck of femur between 2015 and 2017.Analysis of BMD,FRAX scores and patient demographic data was undertaken.RESULTS A total of 69 patients were included in the study,mean age 74.1 years.There was no significant difference between mean BMD of the femoral neck in males(0.65)as compared to females(0.61)(P=0.364).Analyses showed no significant correlation between BMD and menopause age(rs=-0.28,P=0.090).A significant difference was seen of the femoral neck BMD between the different fracture pattern types(P=0.026).A stronger correlation was observed between BMD of femoral neck and FRAX major score(rs=-0.64,P<0.001)than with BMD of lumbar spine and FRAX major score(rs=-0.37,P=0.003).CONCLUSION This study demonstrated that BMD of the femoral neck measured by DXA scan is of added prognostic value when assessing patients for risk of fracture neck of femur in combination with the FRAX predictive scoring system.
文摘Introduction: Early surgical treatment (within 48 hours) has been recommended for femoral neck fractures in order to avoid complications and reduce mortality rate, regardless of presence and severity of comorbidity and preoperative status (ASA score). However some studies evidenced that early surgery doesn’t always have a beneficial effect on mortality and complications. Therefore further studies could be useful in order to better assess risk related factors of patients requiring surgical treatment for femoral neck fracture. The purpose of this study is to evaluate the effect of preoperative ASA score and timing of surgery on mortality, complications and clinical outcome. Methods: All 336 patients operated in our center from January 2013 to December 2014 were selected for this retrospective study. Patients were divided in three groups as follows: group 1 patients treated within 48 hours;group 2 patients treated between 48 to 96 hours;group 3 patients treated over 96 hours. The preoperative ASA score was recorded for each patient. Complication, clinical outcome and mortality at one-year follow-up were evaluated. At follow-up ambulation was graded as: confined to bed, assisted ambulation, and normal ambulation. Complications both local (infections, malunion, dislocation) and systemic (deep vein thrombosis, pulmonary embolism, lung infections, ischemic disorders of heart) were recorded as well as number of transfusions. Statistical analysis was performed with chi square test and P value Results: 308 patients’ data were fully available for this study. At one-year follow-up return to normal ambulation was higher for patients of group 1 as compared with group 2 and 3 and in group 2 as compared with group 3 (P = 0.04). There was no difference in mortality and return to ambulation between patients with ASA score 1 and 2 (P = 0.06);patients with ASA score ≥ 3 showed a statistically significant higher mortality (P = 0.004) and rate of complications (0.0008) regardless of timing of surgery. There was no statistically significance in blood transfusion among the three groups. Discussion and Conclusion: Clinical outcome, complications and mortality have been previously reported from many authors and most studies agreed that early surgical treatment is recommended regardless of age and preoperative status of the patient. The present study suggests that early surgical treatment is actually able to reduce mortality and complications and to improve clinical outcome in patients with better preoperative conditions, while for patients with ASA score ≥ 3 treatment within 48 hours seems not to prevent mortality and complications and improve clinical outcome.
文摘Objectives: In this study we aimed to present our treatment results of intramedullary nailing of femoral shaft fractures with compressive nailing using proximal static hole and only distal dynamic hole with one screw. Methods: Forty-three patients who had a fracture of the femoral shaft were managed between 2005 and 2008 with intramedullary nailing and the use of only one screw for distal interlocking. Prospectively we evaluated the union time, possible reoperation, fixation and fracture alignment, range of knee motion and complications. Results: Union occurred within a mean duration of 18.7 weeks. No failures of the fixation and fracture alignment and no more than 1 cm shortness were detected. The knee range of motion was all more than 90 degree. Only one deep venous thrombosis was detected as complication. Conclusions: Compressive nailing using proximal hole and only distal dynamic hole with one screw is a convenient technique for femur fractures.
文摘BACKGROUND Timely intervention in hip fracture is essential to decrease the risks of perioperative morbidity and mortality.However,limitations of the resources,risk of disease transmission and redirection of medical attention to a more severe infective health problem during coronavirus disease 2019(COVID-19)pandemic period have affected the quality of care even in a surgical emergency.AIM To compare the 30-d mortality rate and complications of hip fracture patients treated during COVID-19 pandemic and pre-pandemic times.METHODS The search of electronic databases on 1st August 2020 revealed 45 studies related to mortality of hip fracture during the COVID-19 pandemic and pre-pandemic times.After careful screening,eight studies were eligible for quantitative and qualitative analysis of data.RESULTS The pooled data of eight studies(n=1586)revealed no significant difference in 30-d mortality rate between the hip fracture patients treated during the pandemic and pre-pandemic periods[9.63%vs 6.33%;odds ratio(OR),0.62;95%CI,0.33,1.17;P=0.14].Even the 30-d mortality rate was not different between COVID-19 non-infected patients who were treated during the pandemic time,and all hip fracture patients treated during the pre-pandemic period(OR,1.03;95%CI,0.61,1.75;P=0.91).A significant difference in mortality rate was observed between COVID-19 positive and COVID-19 negative patients(OR,6.99;95%CI,3.45,14.16;P<0.00001).There was no difference in the duration of hospital stay(OR,-1.52,95%CI,-3.85,0.81;P=0.20),overall complications(OR,1.62;P=0.15)and incidence of pulmonary complications(OR,1.46;P=0.38)in these two-time frames.Nevertheless,the preoperative morbidity was more severe,and there was less use of general anesthesia during the pandemic time.CONCLUSION There was no difference in 30-d mortality rate between hip fracture patients treated during the pandemic and pre-pandemic periods.However,the mortality risk was higher in COVID-19 positive patients compared to COVID-19 negative patients.There was no difference in time to surgery,complications and hospitalization time between these two time periods.
