Erweiterte transforaminale lumbale intersomatische Fusion zur Korrektur kyphotisch fixierter lumbaler Segmente und lumbaler Hypolordosen

Abstract

In all, 25 patients with 33 kyphotic fixed lumbar segments were treated using a complete anterior release of the annulus and anterior longitudinal ligament via a unilateral transforaminal approach. This enabled a lordosizing correction of the segment between 5° and 29° (mean 11.4°) without any neurological or vascular complications. A total of 10 patients treated with an additional posterior osteotomy were corrected 14-29° (mean 19°). There was a loss of reduction of the lordotic correction (mean 1°; range 0-3°) in the X‑ray control at a minimum follow-up of 6 months (range 6-33 months).
