Correction and Stabilization of Secondary Spinаl Deformity

Abstract

Objective. To summarize the experience of surgical treatment of patients with secondary spinal deformities. Materials and Methods. Forty one patients with kyphoscoliotic postlamynectomy and iatrogenic III-IV grade spinal deformities were treated. Secondary deformities developed after spinal cord tumor removal in 28 patients, and after surgical intervention for spinal injuries and tumors-in other patients. After the estimation of deformity mobility and all examinations the surgery planning was performed including selection of surgical approach and definition of correction level. Results. Average magnitude of scoliotic deformity at admission was 103 degrees, that of kyphotic deformity-87 degrees. Correction after surgical treatment was 46 % for scoliotic deformity, and 67 %-for kyphotic one. Conclusion. The use of combined approaches and modern instrumentation in conjunction with comprehensive examination of patient and thorough preoperative planning allows to recieve good treatment results.
