Summary
Ankylosing spondylitis flexion deformity can be corrected with Dorsal Lordosating Spondylodesis (DLS). This surgical technique restores upright posture and horizontal vision with lower complication rates.
Area of Science:
- Spine surgery
- Orthopedics
- Biomechanical correction
Context:
- Advanced ankylosing spondylitis often leads to severe flexion deformity.
- Corrective surgery is necessary to restore function and quality of life.
- Existing monosegmental methods have high complication rates.
Purpose:
- To introduce and evaluate the Dorsal Lordosating Spondylodesis (DLS) technique.
- To assess the efficacy of DLS in correcting severe spinal flexion deformities.
- To compare complication rates of DLS with monosegmental approaches.
Summary:
- The Dorsal Lordosating Spondylodesis (DLS) is a polysegmental correction and transpedicular fixation technique.
- This method utilizes USIS implants to restore lumbar lordosis and achieve an upright posture.
- Results from 173 patients demonstrate successful correction, improved body height, pain relief, and restoration of horizontal vision.
Impact:
- DLS offers a safer alternative to monosegmental correction due to distributed osteotomies.
- The procedure significantly improves patient quality of life by restoring a horizontal visual axis.
- Sustained positive outcomes, including maintained horizontal vision up to 5 years post-surgery, were observed.
