Abstract

Objectives: To evaluate the outcomes of traditional Kerrison-assisted decompression for thoracic spinal stenosis with myelopathy caused by ossification of the ligamentum flavum at the Spine Surgery Department of Viet Duc University Hospital from January 2020 to January 2025. Methods: This was a retrospective, and descriptive study. Results: Among the study patients, the male-to-female ratio was 1.55:1, and the mean age was 51.7 ± 11.6 years. Surgical details included: an average of 1.8 ± 1.2 decompressed levels, a mean operative time of 62.8 ± 15.4 minutes, an average blood loss of 288.4 ± 66.8 mL, and a mean hospital stay of 5.8 ± 2.2 days. Postoperative outcomes were primarily good and fair, accounting for 41.2% and 48.4% of patients, respectively. Complications included spinal cord injury (9.2%), dural tears (11.8%), postoperative cerebrospinal fluid (CSF) leakage (8.5%), and epidural hematoma (7.8%). Incisional infection accounted for 2.6% of complications, delayed bone fusion for 3.3%, and implant failure for 1.9%.  Conclusion: Thoracic spinal stenosis is an uncommon condition with insidious progression that can lead to severe spinal cord compression and injury. Surgical decompression of the thoracic spinal cord carries a high risk of intraoperative and postoperative neurological injury. This presents a major challenge for surgeons.
