METHOD:
Pedicle subtraction osteotomy is one of the well established and popular techniques for kyphosis correction. 52 patients with dorsolumbar kyphosis followed up for a minimum period of 2 years after pedicle subtraction osteotomy were assessed prospectively for clinico-radiological and functional outcomes. Unacceptable cosmesis and severe back pain were the chief complaints preoperatively.

RESULTS:
The average kyphosis at last follow-up was 8.4° compared to preoperative kyphosis of 58°. Union at the osteotomy site was achieved in all patients, and there were no major neurological complications. All patients showed a significant improvement in all subsets of Scoliosis Research Society (SRS-30) outcome measures following the surgery.

CONCLUSION:
A greater degree of kyphosis correction (>40°) can be obtained with a single pedicle subtraction osteotomy at the dorsolumbar level with minimal neurological complications.
