Abstract

OBJECTIVE
The authors describe four patients in whom we performed a single stage, pedicle subtraction and extension wedge osteotomy for the correction of sagittal imbalance by creating lumbar lordosis. METHODS: One patient presented with congenital hemivertebra, one with post-laminectomy kyphosis, and two with lumbar degenerative kyphosis. All patients suffered from back pain and were unable to walk due to forward stooping of the trunk. We performed a single stage, pedicle subtraction and extension wedge osteotomy for the correction of sagittal imbalance. RESULTS: The angles of correction were 37, 44, 45, and 49 degrees. No case had any neurologic complication. All patients reported complete relief of back pain and were able to upright standing. CONCLUSION: Single-level wedge osteotomy and reduction provide excellent sagittal correction of rigid kyphotic deformities in the lumbar lesion without neurologic compromise.
