Abstract
Objective. To analyze results of surgical treatment of Scheuermann’s kyphosis using segmental instrumentation. Material and Methods. Sixty eight operated patients were divided into two groups. Patients from Group 1 underwent only posterior procedure in skeletal traction, and patients from Group 2 - anterior and posterior procedures. In 18 (26.4 %) cases, patients were treated using segmental vertebrotomy and formation of compression anchor at the apex of deformity. The caudal anchor of instrumentation using transpedicular screws was formed in 10 (14.7 %) patients. Results. Kyphosis decreased from 76.2° ± 11.3° to 42.4° ± 10.4° in Group 1, and from 80.1° ± 11.5° to 39.5° ± 12.2° in Group 2; the loss of correction at 1 year after surgery was 7.9° ± 4.4° in Group 1, and 2.9° ± 5.8° in Group 2. The use of transpedicular fixation reduces the length of instrumentation by one segment. Conclusion. Two-stage surgical treatment including skeletal traction from calvarial bones to supramalleolar area, discectomy and interbody fusion with bone autograft at the apex, and correction of spinal deformity with segmental instrumentation, is the most effective treatment technique for severe progressive kyphosis in Scheuermann’s disease.
