Pedicle subtraction osteotomy for kyphotic deformity in old thoracolumbar fracture: evaluation of Cobb angle

doi:10.3969/j.issn.2095-4344.2014.53.013

Abstract

Abstract:

BACKGROUND: Old kyphotic deformity often needs orthopedic surgery strategy. The most common approaches include anterior, posterior, anterior combined with posterior for the treatment of old kyphotic deformity in old thoracolumbar fracture. However the clinical efficacy remains unclear.
OBJECTIVE: To explore the feasibility of pedicle subtraction osteotomy and pedicle screw implantation for treating kyphotic deformity in old thoracolumbar fracture, and evaluate therapeutic effect with sagittal Cobb angle measurement.
METHODS: A total of 26 patients with kyphotic deformity in old thoracolumbar fracture were recruited from Bazhong Central Hospital between July 2005 and February 2011, and were randomly divided into experimental group and control group, with 13 patients in each group. The control group of patients were treated with the surgery through anterior combined with posterior approach, while the experimental group of patients received pedicle subtraction osteotomy. The therapeutic effect of two groups was compared.
RESULTS AND CONCLUSION: Compared with the control group, the patient of the experimental group showed shorter operation time and less intraoperative blood loss, postoperative Cobb angle was significantly decreased, neurological functions were recovered better, and the incidence of complications was lower. Pedicle subtraction osteotomy is an effective strategy for treating kyphotic deformity in old thoracolumbar fracture, which deserves further promotion.
