摘要
目的探讨股骨头负重区抽血量及性状在预测股骨颈骨折继发股骨头缺血性坏死AVNFH)的临床意义。方法采用闭合复位中空钉内固定手术治疗股骨颈骨折61例,术中经中空钉抽吸股骨头负重区的出血,依据抽血量及性状将患者分为血供丰富组51例和血供受损组10例,平均随访41.1个月。结果AVNFH率为19.7%(12/61)。其中,血供丰富组为3.9%(2/51),血供受损组为100.0%(10/10)。灵敏度为83.0%,特异度为100.0%,阳性预测值为100.0%。结论术中经股骨头负重区中空钉孔道抽血观察负重区血供情况,能有效预测股骨颈骨折后AVNFH。
Objective To investigate the value of sucking blood from superior portion of the femoral head in predicting avascular necrosis of the femoral head（AVNFH）.Methods Sixty-one patients with femoral neck fracture were treated with cannulatcd screws.According to the status of bleeding sucked through the holes of proximal cannulated screw,the patients were divided into groups of A（with abundant blood,51 cases）and B（blood circulation absence,10 cases）.The incidence of AVNFH was recorded during averaged 41.1 months followed up.Results AVNFH developed in 11 cases（19.7%）of 61 cases.The incidence rate was 3.9% in group A and 100.0% in group B with the sensitivity of 83.0%,the specificity of 100.0% and positive predictive value of 100.0%.ConclusionThe status of bleeding sucked through the holes of proximal cannulated screw from the superior portion of the femoral head can be taken as a marker for predicting the development of AVNFH after femoral neck fracture.
