摘要
[目的]探讨颗粒骨打压植骨在腰椎后路融合手术中应用的可行性。[方法]2003～2006年之间在本院行腰椎颗粒打压植骨融合的病人取得随访的31例,男14例,女17例;年龄55～80岁,平均66.2岁。[结果]术后无硬膜撕裂、伤口感染等并发症。3例病人术后出现下肢放射痛,3个月左右缓解。术后6个月时摄X线片13例愈合,12个月时16例愈合,其余2例在术后18个月时愈合。随访结果:本组病人优16例,良12例,可3例,差0例。术后JOA评分24～29分,平均(27.4±1.9)分。术后改善率89.4%。[结论]颗粒骨打压植骨在腰椎后路椎间融合手术的应用操作相对简单,费用低,损伤小,融合率高,是一种值得推荐的手术方法。
[ Objective ] To investigate the feasibility of posterior interbody parvule - impacted bone graft fusion. [ Method] A retrospective study was performed in 31 patients admired to our hospital in 2003 -2006 （ M = 14, F = 17） . The ages were 55 to 80, with an average of 66. 2 years. There were 9 cases of spondylolisthesis, 6 of degenerative unstability and 16 of developmental stenosis. All patients underwent posterior interbody impact bone graft fusion and pedicle screw fixation. The preand post - operative JOA score were used to calculate the improvement rate . The postoperative bending - extending plain films were taken to observe whether the fusion was successful. [ Result] All patients were followed up for 12-18 months. Three patient had leg symptoms at postoperation and were released 3 months later. Thirteen patients had fusion at 6 month, 16 had union at 12 month , and 2 had union at 18 month. The lumbar lordosis angle and intervertebral height got significant restoration. The spinal fusion rate was 100%. No dura tear leakage of cerebrospinal fluid or wound infection was found. No graft absorption, displacement or collapse occurred. There were 16 cases excellent, 12 cases good, and 3 cases fair. JOA score was 24 -29 （average 27.4±1.9） at postoperation. The improvement rate was 89.4%. [ Conclusion] Posterior interbody parvule- impacted bone graft is a feasible fusion method. The method is simple and cheap, with advantages of less injury and high fusion rate.
