The fate of anterior autogenous bone graft after anterior radical surgery with or without posterior instrumentation in the treatment of pyogenic lumbar spondylodiscitis.

摘要: Study Beirign. A retrospective clinical study. Objective. To assess the results of anterior strut grafting and loss reduction in interbody fusion combined with posterior instrumental pyogenic spondylodiscitis. Summary Background Data. Resorption graft is an ominous sign following most surgery. Thus, additional instrumentation has been used to prevent collapse graft. However, its effect controversial, few studies have examined fate Methods. Twenty-four consecutive patients under-went surgical treatment for The were divided into Group I (anterior fusion) II + instrumented fusion). sagittal angle, interverte-bral height, complications relating compared. Results. Solid bone was achieved 23 (95.8%) patients. angle intervertebral height similar Groups (P= 0.61, P= 0.89, respectively). In II, postoperative maintained until 1 month after surgery (P> 0.05), but it decreased significantly by 3 months (P surgery, had collapsed (P<0.05). Subsidence occurred through damaged endplate. included case dislodgement necessitating revision; there no such cases II. There recurrences infection either group. Conclusion. Reduction profile both groups. Complications more common than Despite correction, groups a high rate without recurrence infection. appears be result destruction endplate due debridement or infective process.
