Abstract:
Objective: To explore the clinical efficacies of transpedicular lumbar wedge resection osteotomy for correction of kyphosis in ankylosing spondylitis. Methods: From January 2005 to March 2010,32 patients with ankylosing spondylitis kyphotic deformity received one stage posterior transpedicular wedge osteotomy and internal fixation, with 27 receiving single-level ones and 5 receiving two-level ones. All patients underwent X-ray examination of the total spine to obtain radiographic parameters and were asked to accomplish simplified Chinese scoliosis research society-22 (SRS-22) questionnaire to assess quality of health before and after operation. Results: The mean operation time was (260±42) mi n and the mean blood loss was (1 360±282) mL in the patients. The patients were followed up for a mean of (31±8) months (range: 24-76 months) and there were no neurological complications and pseudarthrosis. The chin-brow vertical angle (CBVA), global thoraco-lumber kyphosis angle (TLKA), thoracolumbar kyphosis angle (TKA) and lumber lordosis angle (LLA) were (65. 9±11. 6)° (78. 2±15. 9)° (38. 9±10. 3)° and (-14. 6±17. 3)° before operation and (11. 7±4. 7)°, (38. 9±10. 3)°, (1. 3±7. 8)° and (26.2±5. 6)° after operation, respectively; and significant differences were found for each parameter (P<0. 01). The body height and the sagittal imbalance distance were improved from (135. 4±15. 2) cm and (37. 2±11. 3) cm before operation to (166.2±9. 6) cm and (12. 7±7. 7) cm after operation, respectively. The average SRS-22 score increased from (1. 8±0. 4) before operation to (4. 0±0. 6) after operation, showing a satisfactory outcome. Conclusion: Transpedicular lumbar wedge resection osteotomy is a safe and effective method for treatment of the ankylosing spondylitis kyphosis.
