ABSTRACT

Objective To analyze the cause and treatment of the postoperative complications using one-stage posterior spinal osteotomy in the treatment of severe spinal deformity.Methods From September 2006 to May 2013,17 patients with severe spinal deformity (congenital scoliosis in 11 cases,congenital kyphosis in 4 cases,and congenital kyphoscoliosis in 2 cases) underwent one-stage posterior spinal osteotomy,including 5 males and 12 females with an average age of 22.6 (14-51) years.The preoperative mean coronal Cobb angle was 109° (85°-160°) while the mean sagittal Cobb angle was 104° (65°-152°).Two patients had neurological symptoms preoperatively whose spinal cord function was D,evaluated by ASIA classification.All patients were treated with pedicle subtration osteotomy and pedicle screw internal fixation,which SPO osteotomy 2 cases,PSO osteotomy 11 cases,VCR osteotomy 4 cases.Results There were 17 cases of complications in 147 patients,the complication rate was 11.6%(17/147).The causes were as followed,screw malposition in 2 cases,compromised by close of resected areas in 2 case,residual bone compression in 1 case,acute spinal cord injury in 2 cases,infection in 2 cases,broken stick or loosen hat in 3 cases,and superior mesenteric artery syndrome in 5 cases.Postoperative neurological complications occurred in 7 cases.Two cases with preoperative ASIA D became ASIA C,5 cases with normal nerve function became ASIA C in 2 cases and ASIA D in 3 cases.After surgical exploration,given Methylprednisolone and neurotrophic drugs,removal or changing of the internal fixation,anti-infection and symptomatic treatment,15 cases recovered completely and 2 cases improved partially.Conclusion One-stage posterior spinal osteotomy for severe spinal deformity is technical demanding and risky,and the postoperative complications are common.Appropriate operative procedure,close observation of sensation and motor function,timely surgical exploration and nerve decompression,and early brace wear are all required.

ABSTRACT

BACKGROUND:Idiopathic scoliosis is most common among al the scoliosis. Accompanied by the nervous system, the endocrine system as wel as nutritional and metabolic abnormalities, patients usual y cannot be redressed and cured by conservative treatment, but often require surgical operation. Surgery for malformation is a very complicated project, and is real y of great significance for an in-depth research on treatment and turnover of idiopathic scoliosis. OBJECTIVE:To observe the correction effect of posterior screw-rod fixation for idiopathic scoliosis, and explore the relevant factors influencing its effectiveness. METHODS:We retrospectively analyzed 80 cases receiving pedicle screw fixation in the treatment of idiopathic scoliosis in the latest four years. Age, gender, disease duration, preoperative and postoperative X-ray measurement of coronal Cobb’s angle, and trunk deviation were recorded, and statistical y analyzed. RESULTS AND CONCLUSION:Univariate analysis showed that gender and disease duration were not significantly correlated with postoperative correction results (P>0.05). However, the age distribution of patients, the location of scoliosis, and scoliosis flexibility were associated with curative effects of internal fixation (P<0.05). Posterior screw-rod fixation for idiopathic scoliosis can achieve significant effects. The patient’s age, location and flexibility of scoliosis have a significant effect on the effects of fixation. The patient’s gender and disease duration had no significant effect on fixation effects.
