Early corset reclination of uncomplicated type А3 comminuted vertebral fractures in the thoracolumbar spine

Abstract

Objective. To analyze the results of staged preoperative correction of uncomplicated comminuted fractures in the thoracolumbar spine.Material and Methods. Retrospective study included data from 51 patients (33 men and 18 women) 17–35 years old with type A3 spinal injuries without urgent indications for surgery. In preparation for a possible operation, patients received a corset treatment with reclination pneumopelot for 2–3 days.Results. The results were evaluated based on clinical, radiological and CT data. The result after reclination corset treatment was considered good if a restoration of the vertebral height was achieved with its residual deficit of less than 10 % or local wedge shape not more than 10°; satisfactory – with a residual decrease in vertebral body height from 10 to 30 % or in kyphotic deformity from 10 to 20°; and unsatisfactory – with a decrease in body height of more than 30 %, and in kyphotic deformity of more than 20°. With an average decrease in the height of the fractured vertebral body before surgery by 45 % and the local kyphosis magnitude of 27.0° ± 5.5°, the staged reclination provided complete correction of kyphosis in all cases and restoration of the height of the compressed vertebra to a residual deficit of less than 10 % in 78 % of cases. Neurological disorders were not noted.Conclusion. In case of incomplete burst vertebral fractures not complicated by compression of the spinal cord, the method of early (in the first 7 days after the injury) corset treatment with staged fracture reclination by a pneumatic chamber can be effectively used to eliminate local kyphotic deformity and restore the height of fractured vertebra.
