Background

Degenerative lumbar kyphosis (degenerative lumbar kyphosis) is a common cause of sagittal imbalance, pain, and functional disability.

Methods

A retrospective single-center case series was conducted including 215 consecutive patients with symptomatic degenerative lumbar kyphosis and pelvic incidence-lumbar lordosis (pelvic incidence-lumbar lordosis) mismatch >10° treated between 2019 and 2023.

n = 215 consecutive patients

Results

average gain in lumbar lordosis from surgery, with correction maintained through 24 months

Preoperative LL

15.7°

LL at 24 months

45.4°

More results

Significant improvements were observed in pelvic tilt, sacral slope, Visual Analog Scale, Oswestry Disability Index, and SF-36 scores (all p < 0.001), with maintenance of correction throughout follow-up.

Mean operative time was 218.4 ± 47.3 min and mean blood loss was 483.2 ± 195.7 mL.

More results

The overall complication rate was 16.3%, with incidental durotomy being the most common event (14.9%).

Conclusion · 1 of 2

Posterior Interpedicular Osteotomy combined with bilateral discectomy and hyperlordotic transforaminal lumbar interbody fusion achieved substantial and durable sagittal correction with significant clinical improvement and an acceptable safety profile.

Conclusion · 2 of 2

By combining extensive posterior release with preservation of the anterior tension band, this technique may represent an effective intermediate alternative between conventional posterior column osteotomies and more invasive three-column deformity correction procedures.
