title: Functional outcome after partial reduction and 360 degree fusion in grade III-V spondylolisthesis in adolescent and adult patients.
abstract: Reduction of high-grade spondylolisthesis is a surgically demanding procedure, which has been reported to incur a relatively high risk of neurologic damage, pseudoarthrosis, and other complications. The aim of this study was to evaluate the radiographic and functional outcome in spondylolisthesis grade III-V, surgically treated with posterior decompression, L4- or L5-S1 CD instrumentation, partial reduction, and posterolateral fusion followed by anterior interbody fusion L5-S1 ad modum Kellogg-Speed. Thirteen patients, mean age 23.8 (range, 11-33) years were followed for mean 28.5 (range, 19-52) months. The anterior slip, lumbosacral angle, sagittal rotation angle and L4/SI angle were significantly improved from preoperatively to follow-up. No patients had neurologic, vascular, thromboembolic, or lung complications. Twelve patients reported a better or unchanged (3 patients) physical and emotional status. At follow-up, 10 patients were in full-time jobs or back to school. The method was safe and provided a stable rigid fixation with partial reduction of the deformity and a satisfactory functional outcome.
