To evaluate the results of TSRH instrumentation in the correction of coronal, sagittal and rotational deformity of scoliosis. Methods. From January 1998 to December 1999, thirty- two consecutive patients (6 males, 26 females) with scoliosis underwent anterior or posterior spinal instrumentation and fusion using TSRH instrumentation. Of these cases, 21 were idiopathic scoliosis and 11 were congenital scoliosis. The average age at surgery was 16.4 years (range, 11～ 45 years). The mean Cobb angle at surgery was 71 .2 (range, 44～ 125 ) in the coronal plane, and 49.2 ( range, 16～ 67 ) in the sagittal plane. Rotational deformity (Nash- Moe) ranged from I to III degree. Preoperative apical translation averaged 4.8 cm (range, 3～ 9 cm). Results. The average follow- up duration was 13.3 months (range, 10～ 24 months).At the final follow- up, the mean Cobb angle in the coronal plane was 26. 6 (range, 10～ 73 ),with a 63.8％ of improvement. Sagittal alignment was well maintained with a mean Cobb angle of 28 ( range, 10～ 45 ). The average correction of rotation of the apical vertebra was I degree. The average apical translation was 1.6 cm (range, 0.5～ 5.0 cm) representing a correction rate of 66,7％ . Complication was noted in two cases with an incidence of 3.1％ , one case had superficial infection and the other one had lower hook dislocation.There was no neurologic deficit and pseudoarthrodesis in this series. Conclusion. TSRH instrumentation is an effective and convenient three- dimensional correction system with a lower rate of complication, which can not only correct the coronal and rotational deformity, but maintain the sagittal alignment as well.展开更多

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 operation and 10. 8 mm (3-20 mm) after operation. The distance of C7 to center sacrum vertical line (CSVL) was 19. 5 mm(16 - 42)preoperatively and 11. 3 mm (0-32 mm) postoperatively. The apical vertebra rotation was 3 degree in 15 patients preoperatively, and were improved to normal in 10 patients, 1 degree in 4 patients, and 2 degree in 1 patients postoperatively. None had neurological injury and infection. Only 1 patient complained a cool feeling in the low extremity of concave side, and the symptom vanished at 3-month followed up.Conclusion. If used appropriately, TSRH anterior spinal system is a good treatment for low thoracic or thoracic lumbar scoliosis.展开更多
