ANTERIOR SPINAL FUSION WITH TSRH INSTRUMENTATION FOR SCOLIOSIS

Objective. To introduce a new spinal internal fixation system, Texas Scottish Rite Hospital (TSRH), and to investigate its early clinical outcomes.Methods. The preliminary clinical outcomes of 15 patients with thoracolumbar or lumbar scoliosis treated by anterior spinal fusion with TSRH instrumentation were studied retrospectively. Fourteen patients were diagnosed as idiopathic scoliosis and 1 as neuromuscular scoliosis.Results. Preoperatively, the Cobb’s angle on the coronal plane was 55. 8° (range 35° - 78°), and 14° postoperatively, with an average correction of 74. 8 %. The average unfused thoracical curve was 35. 9 ° preoperatively (range 26° - 51°) and 21. 8° (10°-42° ) postoperatively, with 40% correction. The sagittal curve of lumbar was kept physiologically, preoperative 27. 9° and postoperative 25. 7° respectively. The trunk shift was 13.4 mm (5 - 28mm) preoperatively and 3. 5 mm (0-7 mm) postoperatively. The averaged apic vertebra derivation was 47. 8 mm (21 - 69 mm) before operat
