Abstract Dual-blade plate is widely used in reconstruction of anterior stability of spine. Two hundred and ninety-eight cases were followed up since 1984. Among them, 181 cases were fractureof thoracolumbar spine; 63 cases were tuberculosis of thoracolumbar spine; 43 cases were tumor of thoracolumbar spine; 5 cases were spondylisthesis of lumbar spine; 2 cases were ankylosing spondylitis accompanied with gibbosity; 2 cases were adolescent vertebral epiphysis; I case was hemivertebra; I case was dysplasia of the first lumbar vertebra acompanied with gibbosity. Most cases were successful following operation, but in some cases, the results were unsuccessful, mainly due to the position of the dualblade plate in the vertebral body was not satisfactory. The mistakes most commonly occurred were one or two blades, or a part of the blade going into the intervertebral space, and less commonly seen was deviation of the dual -blade plate from itscorrect orientation or a little side-bent of the blade. Split of the vertebra and fall off of the dual-blade plate were happened in few cases. The causeswere analyzed and ways of prevention were provided in this article.
【摘要】 目的 探讨强直性脊柱炎合并脊柱骨折脱位的临床特点及手术治疗效果。 方法 2009年10月-2010年6月，共收治6例强直性脊柱炎合并脊柱骨折脱位患者，其中男5例，女1例；年龄38～76岁，平均48.6岁。下颈椎骨折脱位3例，2例为颈5-6、1例颈6-7；胸腰段骨折脱位3例，为胸10-11、胸11-12、胸12-腰1各1例。6例患者中除1例术前神经功能为Frankel分级 E级，其余5例均有不同程度的神经损伤。6例患者均行手术治疗，下颈椎骨折脱位采用前后联合入路复位及固定，胸腰段骨折脱位采用后路切开复位及椎弓根螺钉固定。术后观察手术节段内固定位置及骨融合情况，评估神经功能恢复情况，记录手术并发症。患者随访10~18个月，平均14.2个月。 结果 所有患者术后均未出现切口感染；脑脊液漏1例，换药对症处理3周后愈合。1例颈5-6骨折脱位患者行前路手术后第2天出现内固定移位，骨折椎再次脱位立即二次行前后联合入路复位固定术；3例术后神经功能由术前Frankel C级恢复至D级，2例无明显改善（术前均为A级），1例较术前加重（术前E级，术后为A级，经再次手术减压并康复治疗6个月后恢复至D级）。随访期间均达骨性融合，未出现内固定松动断裂移位现象。 结论 强直性脊柱炎脊柱骨折好发于下颈椎及胸腰段；对于下颈椎骨折脱位宜行前后联合入路复位固定，而胸腰段骨折宜行后路长节段椎弓根螺钉固定，术中应先充分减压后再精细复位，避免加重神经损伤。【Abstract】 Objective To explore the clinical characteristics of spinal fracture and dislocation in ankylosing spondylitis (AS) and its surgical treatment effect. Methods From October 2009 to June 2010, six cases with spinal fractures in AS underwent surgical treatment. There were 5 males and 1 female with an average age of 48.6 years (38-76 years old). The preoperative neural function of one case was grade E according to the Frankel classification and different degrees of neural damage could be found in other 5 cases. Three cases of lower cervical fractures underwent the operation with a combined posterior-anterior approach. Three cases of thoracolumbar fracture underwent the operation with posterior approach (posterior reduction, fixation with pedicle screws and bone graft). The situation of internal fixation and bone fusion was observed after operation, the neural function had been evaluated and the postoperative complications was recorded. Results All of the six patients were followed up for 10-18 months (mean 14.2 months). There was no incision infection. One patient with cerebrospinal fluid leakage was cured with conservative treatment for three weeks. One patient with C5-6 fracture and dislocation got anterior implant loosening and fracture-dislocation recurrence in the second day after the operation and underwent a combined posterior-anterior operation immediately. Three cases got remarkable neuronal function improvement after the operation. Two cases were remain primary situation. One case was aggravated from preoperative grade E grade to postoperative grade A and recovered to grade D after recovery treatment for 6 months. Bone fusion was achieved in all cases. There were no loosening and breakage of internal fixation in the later followed up. Conclusions Lower cervical and thoracolumbar spine are the usual locations of fracture in AS. A combined posterior-anterior surgical approach is effective for lower cervical fractures and posterior long-segmental reduction and the fixation is a desired select for thoracolumbar fractures.

Objective To elucidate the surgical indicationsand treatment outcome of total spondylectomy and reconstruction for thoracolumbar spinal tumors with neurological deficit. Methods From January 1999 to December 2005, 16 patients with thoracolumbar spinal tumors with neurological deficit were treated with total spondylectomy and reconstruction. There were 10 males and 6 females, with an average age of 31.5 years(16-62 years).There were 10 cases of primary tumors of spine (4 giant cell tumor of bone, 3 chondrosarcoma, 2 recurrent aneurysmal bone cyst, and 1 osteosarcoma), and 6 cases of solitary metastasis of thoracic or lumbar spine. Tomita’s surgical classification was as follows: 9 cases of type 4, 6 of type 5, and 1 of type 6. Frankel’s neurological classification was as follows: grade A in 1 case, B in 4, C in 7,and D in 4. All patients were treated with total spondylectomy and reconstruction through combined anterior and posterior approach. Results All patients were followed up from 10 to 63 months with an average of 27.5 months. Pain was relieved completely in all patients. The neurological function returned to grade D in 5 cases, to grade E in 11 cases. Among the 10 patients with primary spinal tumor, nine patients survived with tumor-free, and one with osteosarcoma died because of lung metastases 18 months after surgery. Among the 6 patients with spinal metastasis, three patients survived with tumorfree, and lung metastasis occurred in 1 case 10 months after surgery, two died because of multiple metastases of internal organs 10 months and 32 months after surgery. Conlusion Total spondylectomy and reconstruction is a safe and effective surgery for thoracolumbar spinal tumors with neurological deficit, with pain relief, neurological improvement and minimum tumor recurrence. It will be an optimal choice for patients with primary malignant, aggressive benign, or solitary metastatic bone tumors of the thoracolumbar spine with Tomita surgical classification type 3 to 5.
ObjectiveTo analyze the curative effect of vacuum sealing drainage for early deep infection after posterior spinal internal fixation. MethodsFrom March 2009 to March 2012, 9 patients with early deep infection after posterior spinal internal fixation, including 5 males and 4 females aged between 21 and 64 years, averaging at 44.6, underwent debridement and vacuum sealing drainage (VSD). Original fixtures in all the patients were not taken out. ResultsThe patients were treated by VSD for once to three times with an average of 2.1 times, and VSD continued for 3 to 7 days every time. Two patients underwent one time of VSD, 4 underwent twice, and 3 underwent three times. In these patients, 6 achieved wound healing after VSD, one changed to ordinary dressing and wound suturing two weeks later due to hemorrhage of VSD, one changed to ordinary dressing and wound suturing wound three weeks later due to impeded drainage, one accepted skin-grafting after three times of VSD. All the patients were followed up for 6 to 38 months (18 months on average) and all of them were cured. There was no obvious back pain or signs of incision infection. The X-ray films showed that there were no bone destruction and the white blood cell count, erythrocyte sedimentation rate, and C-reactive protein significantly decreased to normal after surgery. ConclusionOne-stage debridement and vacuum sealing drainage therapy is an effective method for treating early deep infection after posterior spinal internal fixation.

To explore the advantage and indication of combined anterior and posterior surgeries for lumbarsacral junction tuberculosis. Methods Eleven cases of the lumbarsacral junction tuberculosis were treated with combined anterior (radical debridement and autograft) and posterior (instrumentation and fusion) surgeries in one stage between January 2002 and December 2006. There were 9 males and 2 females with the age of 20-56 years old. The courseof disease was 4 to 15 months, 6 months on average. The lessons were located at L5, S1 in 7 patients, at L4,5, S1 in 2 patients and at L5, S2 in 2 patients. The involved vertebral bodies were at 2 segments in 7 patients; and 3 segments in 5 patients. The preoperative kyphosis was 5 to 8° with an average 9°. The sinus was associated in 3 patients, 3 patients had radiculopathy; 4 had paeumonophthisis and 9 had abscess. Results The followed-up period was from 6 months to 3 years, 18 months on average. According to Chen score, among the 11 cases, there were excellent in 9, good in 2. All incisions were healed up primarily. After operation, spinal fusion was achieved in 10 cases within 5 months to 7 months, 6 months on average, and pseudoarthrosis in 1 case was found by the CT examination. The postoperative kyphosis was 0 to 4° with the mean of 2° and the radiculopathy in 3 cases all got nerve function recovery. Conclusion Lumbarsacral junction tuberculosis treated with this surgical technique can achieve a high satisfactory rate with restoring the spinal stabil ity, arresting the disease early, providing early fusion, correcting the kyphosis and preventing progression of kyphosis particularly if lumbosacral spine tuberculosis is associated with sinus or preoperative diagnosis cannot exclude suppurative spondyl itis.
【Abstract】 Objective To explore the effectiveness of multiple joint arthroplasty in treating lower limb joint disease. Methods Between January 2000 and December 2007, 5 patients with lower limb joint disease (three or more joints were involved) were treated with total hip and knee arthroplasty. There were 3 males and 2 females, aged from 27 to 59 years (mean, 41.8 years). Two patients had ankylosing spondylitis and 3 had rheumatoid arthritis, whose hip and knee joints were involved. Four patients lost the ability of walking preoperatively, 1 patient could only walk with crutch. The Harris score was 24 ± 24 and the Hospital for Special Surgery (HSS) score was 28 ± 15. All patients underwent multiple joint arthroplasty simultaneously (2 cases) or multiple-stage (3 cases). Results Wounds healed by first intention in all patients. In 1 patient who had dislocation of the hip after operation, manipulative reduction and immobilization with skin traction were given for 3 weeks, and no dislocation occurred; in 2 patients who had early sign of anemia, blood transfusion was given. All patients were followed up 46-140 months with an average of 75 months. The patients could walk normally, and had no difficulty in upstairs and downstairs. The stability of the hip and knee was good, and no joint infection or loosening occurred. The Harris score was 88 ± 6 at last follow-up, showing significant difference when compared with the preoperative score (t=8.16, P=0.00); the HSS score was 86 ± 6, showing significant difference when compared with the preoperative score (t=13.96, P=0.00). Conclusion Multiple joint arthroplasty is an effective treatment method in patients with lower limb joint disease, which can significantly improve life quality of patients.
