ABSTRACT |
OBJECTIVE The purpose of this retrospective study is to review the clinical results, fusion rate, quality of reduction and stabilization and effects of cages in the intervertebral space in spondylolisthesis. METHODS Authors reviewed retrospectively 30 patients who were treated with instrumentation and posterior lumbar interbody fusion(PLIF) between April 1996 to December 1997. RESULTS Among 30 patients, 13 patients were degenerative type and 17 were isthmic types. The most commonly involved level was L4-5(16cases, 53.3%). Fusion was obtained in 29 patients(96.7%). Clinically, 14 of 17 patients(82.3%) showed excellent or good results in isthmic group, and 11 of 13 patients(84.6%) showed excellent or good results in degenerative group. Postoperative complications developed in three cases(10%), wound infection two cases(6.6%), cage retrodisplacement one case(3.3%). CONCLUSION PLIF combined with transpedicular instrumentation in lumbar spondylolisthesis showed in all clinical results and fusion rate. |
