Combined anterior and posterior surgery for treatment of cervical fracture-dislocation in patients with ankylosing spondylitis / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To discuss the pathological characteristics of cervical spinal fracture complicating ankylosing spondylitis (AS) and the effect of combined anterior and posterior operation.</p><p><b>METHODS</b>Eighteen AS patients with traumatic cervical fracture-dislocation were treated operatively from January 2000 to January 2006. The symptom duration of AS was 14.5 years on average. Three cases had undergone osteotomy in lumbar spine. There were 4 cases of Grade A, 3 cases of Grade B, 9 cases of Grade C and 2 cases of Grade D according to Frankel's score. There were 15 cases of Grade III dislocation and 3 cases of Grade II. All patients underwent surgical procedures by combined anterior and posterior approach.</p><p><b>RESULTS</b>There were 4 anterior-posterior procedures, 8 anterior-posterior-anterior procedures and 6 posterior-anterior procedures. Seven patients had one stage operation and 11 cases underwent two stage surgeries. There was certain extent of neurological improvement in 14 incomplete paraplegic patients, but no improvement in 4 complete paraplegic patients. The follow-up period was 21.2 months on average and the time for bone fusion was 3.6 months. There were 4 complications during operation and a long-term complication in follow-up.</p><p><b>CONCLUSIONS</b>The study suggests that anterior combined with posterior approach makes the spine stable and relieves the pressure immediately. It is a reasonable surgical strategy for treatment of cervical spinal fracture-dislocation with AS.</p>

One stage posterior vertebral column resection for the treatment of thorciclumbar tuberculosis with kyphotic deformity / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the clinical outcome of one stage posterior vertebral column resection in patients with spinal tuberculosis combined with kyphotic deformity.@*METHODS@#Thirty-six patients with spinal tuberculosis combined with kyphotic deformity underwent posterior one-stage vertebral column resection reducing tension on the spinal cord from 1998 to 2006. The patients were mobilized with a thoracolumbar orthosis for 3 months. All patients had a minimum of a 2-year follow-up, and clinical examinations and radiographs were obtained at 6-month intervals.@*RESULTS@#No perioperative mortality occurred. The average duration of surgery was 208 (145 approximately 385) min. The kyphotic Cobb angle improved from the preoperative average of 57.2 degree(17 degree approximately 86 degree) to a postoperative average of 8.9 degree(-6 degree approximately 27 degree). The average horizontal distance between C(7) and S(1) was 13.6 (8 approximately 19) mm preoperatively and 3.6 (-11 approximately 9) mm postoperatively. Nineteen patients had preoperative neurological deficits. Of them, 89.5% (17/19) showed a postoperative neurologic improvement. Perioperative complications occurred in 3(8.5%) of the 36 patients with pneumonias and superficial infections. Twenty-five patients (69.4%) showed radiographic evidence of solid fusion in the follow-up examinations. In the follow-up, 25% (9/36) patients rated their results as excellent, 66.7% (24/36) as good, 2 as fair, and 1 as poor.@*CONCLUSION@#One stage posterior vertebral column resection for the treatment of spinal tuberculosis with kyphotic deformity is safe and effective. Because this procedure is highly technical, the surgeon must be familiar with the pathoanatomy and the operation must be carefully done.

Screw-rod technique in treating cervical spinal cord injury without fracture and dislocation / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the efficacy of screw-rod technique in treating cervical spinal cord injury without fracture and dislocation.@*METHODS@#The screw-rod technique was used to treat 38 patients with cervical spinal cord injury without fracture and dislocation. The JOA scores before and after the surgery were evaluated.@*RESULTS@#No severe complication occurred. The JOA scores were increased by 4.1, 6.7, 7.8, and 8.1 respectively at 0 th, 4 th, 12 th and 24 th weeks after the operation. Neurological deficits were improved one year after the operation in 1 patient.@*CONCLUSION@#Treating cervical spinal cord injury without fracture and dislocation with screw-rod technique can achive an efficient and safe clinical outcome.

Research on complications of thoracoscopic assisted thoracic spine surgery / 中华外科杂志

<p><b>OBJECTIVE</b>To analyze occurrence, prevention and treatment of the complications of thoracoscopic assisted spine surgery.</p><p><b>METHODS</b>Retrospective review of 182 patients who underwent standard thoracoscopic technique or video-assisted thoracic surgical procedure from October 1998 to August 2004. The treatment of thoracic diseases included debridement, decompression with (or) reconstruction. The total number of complications were recorded, and its mechanism, prevention and treatment were analyzed.</p><p><b>RESULTS</b>Complications occurred in 16 patients, 12 cases of perioperative complications included 3 patients suffered from pneumonia, 3 pulmonary atelectasis, 2 patients' lung injured by trocar, 1 patient obtained transient monoplegia, 2 suffered from transient intercostal nerve pain and 1 had superficial incision infection. Long-term complications occurred in 4 cases: spinal tuberculosis relapsed 2 cases (one who had diabetes obtained relapse in 8 months of post-operation and another relapsed with complex spinal tuberculosis in 4 weeks postoperation), 2 patients suffered from kyphosis deformity and pain.</p><p><b>CONCLUSIONS</b>The type and incidence of complications with thoracoscopic spine surgery mainly depend on indication, operation procedures and anesthesia, only by limit surgical indication, ameliorate technique, obey surgical principle and consummate perioperative treatment can we obtain mini-invasive effect by thoracoscopic assisted spine surgery.</p>

Surgical treatment of thoracic vertebral angioma with extraosseous extension causing spinal cord compression / 中南大学学报(医学版)

OBJECTIVE@#To evaluate the therapeutical effect of surgical treatment for thoracic angioma with extraosseous extension which causes spinal cord compression and neurological dysfunction.@*METHODS@#We retrospectively analyzed 5 cases of thoracic vertebral body angioma with extraosseous extension and spinal cord compression. The operation were performed through anterior approach to resect the involved vertebral body and intracanal angioma in 5 patients. Bone graft and internal fixation were also completed in the meantime. Two patients accepted radiotherapy for 2 periods of treatment postoperatively, and the other 3 patients didn't accept the other supportive therapy.@*RESULTS@#The blood loss during the operation was 1000 mL to 1500 mL. All the patients recovered their neurological function rapidly after the operation. The patients were followed up for 1 to 4 years, and no patient recurred. The bone graft was solidly fused in all patients. No hardware failure occurred.@*CONCLUSION@#The surgical treatment for thoracic vertebral body and extraosseous angioma with spinal cord compression is effective, reliable, and workable. Good long-term result can be obtained.
