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

There are very few reports of long-term follow-up of surgical treatment in patients with congenital pure kyphosis, and all the reported cases were diagnosed as failure of formation and had an age at the time of surgery of less than 18 years. It is important for orthopedic surgeons to follow the postoperative course of rare cases over 30 years. Here, we present a surgically treated case with ultra-long term follow-up of a 50-year-old patient with congenital pure kyphosis of the lumbar spine. Imaging of the lumbar spine showed six vertebrae and an unsegmented bar at L3-4 causing a pure kyphosis of 54°. The wedge-shaped block vertebra had 4 pedicles with the neural foramen between the pedicles without concomitant disc space, with compensatory thoracic hypokyphosis and lower lumbar hyperlordosis. One-stage correction and fusion surgery using anterior opening and posterior closing osteotomy was successfully performed. Both clinical and radiographic results were excellent and have been maintained for over 30 years postoperatively. The basic principle in the surgical treatment of adult spinal deformity is to achieve and maintain a good global sagittal balance over time. This case reaffirms the importance of spinopelvic harmony.展开更多

目的:探讨颈前路椎间盘切除融合术(anterior cervical discectomy with fusion,ACDF)与颈前路椎体次全切减压融合术(anterior cervical corpectomy with fusion,ACCF)治疗相邻两节段脊髓型颈椎病的临床疗效。方法:对2016年1月至2017年1...目的:探讨颈前路椎间盘切除融合术(anterior cervical discectomy with fusion,ACDF)与颈前路椎体次全切减压融合术(anterior cervical corpectomy with fusion,ACCF)治疗相邻两节段脊髓型颈椎病的临床疗效。方法:对2016年1月至2017年12月收治的相邻两节段脊髓型颈椎病37例患者的临床资料进行回顾性分析,男15例,女22例,年龄43~69岁,平均54.6岁。根据手术方法的不同分为ACDF治疗组(A组,17例)和ACCF治疗组(B组,20例)。记录两组患者的手术时间、术中出血量,比较两组患者术前及术后1、12个月颈椎融合节段Cobb角、颈椎曲度,采用日本矫形外科协会(Japanese Orthopaedic Association,JOA)评分评价临床疗效,并观察两组术后并发症情况。结果:所有患者获得随访,时间12~24个月,平均18.5个月。手术时间、术中出血量A组分别为(106.3±22.6)min、(52.2±26.4)ml,B组分别为(115.6±16.8)min、(61.7±20.7)ml,手术时间组间差异无统计学意义(P>0.05),B组术中出血量大于A组(P<0.05)。术前及术后1、12个月颈椎曲度和颈椎融合节段Cobb角A组分别为(11.28±1.40)°、(17.56±1.90)°、(16.64±1.80)°和(4.93±4.20)°、(9.44±2.60)°、(9.25±2.80)°,B组分别为(10.59±1.20)°、(16.26±2.10)°、(15.76±2.50)°和(4.75±3.90)°、(7.98±2.10)°、(7.79±3.00)°。两组患者术后颈椎融合节段Cobb角、颈椎曲度均较术前明显改善,且A组较B组恢复更明显(P<0.05)。术前及术后1、12个月JOA评分A组分别为9.46±1.70、11.56±1.40、14.86±1.20,B组分别为9.11±1.50、11.40±1.30、15.12±1.60。两组患者术后JOA评分较术前均明显改善(P<0.05),组间同时间段比较差异无统计学意义(P>0.05)。末次随访A组出现吞咽梗阻感2例,cage移位1例,未发生钛板螺钉松动;B组出现吞咽梗阻感4例,钛网沉降2例,钛板螺钉松动1例。结论:两种颈前路减压融合术治疗两节段脊髓型颈椎病,均能有效减压,改善病椎Cobb角及颈椎生理曲度。ACDF术式可直接去除椎间水平的致压物,椎体破坏小,颈椎生理曲度恢复良好;ACCF术式椎体次全切除,操作空间大,易于去除椎体后缘骨赘及钙化的后纵韧带。长期随访显示,ACDF与ACCF术式效果良好,技术成熟,疗效接近。展开更多
