IS LEG NUMBNESS DISSATISFYING FOR PATIENTS AFTER LUMBAR SPINE SURGERY

Abstract

Objective: To evaluate the impact of leg numbness on postoperative patient satisfaction following lumbar spine surgery.

Study Design: Prospective observational cohort study.

Place & Duration of Study: This study was conducted at Department of Orthopaedics & Spine Centre, Ghurki Trust Teaching Hospital, Lahore from June to September 2024.

Methodology: A cohort of 74 patients who underwent lumbar spine surgery was included. Patient satisfaction was assessed using the Visual Analog Scale (VAS) for low back pain (LBP), leg pain (LP), and leg numbness (LN). Functional outcomes were evaluated using the Japanese Orthopedic Association (JOA) score. Preoperative and postoperative scores were compared to determine improvements in symptoms and overall satisfaction.

Results: Postoperative assessments showed significant improvements in LBP, LP, and LN. Leg numbness scores improved from a preoperative mean of 5.81 ± 2.58 to a postoperative mean of 1.55 ± 1.90 (p < 0.001). However, 18% of patients reported dissatisfaction with the surgical outcome, with persistent leg numbness identified as a major cause. A significant correlation was found between preoperative and persistent postoperative leg numbness.

Conclusion: Although lumbar decompression surgery is effective in reducing pain, leg numbness remains a notable factor contributing to postoperative dissatisfaction. Properly addressing patient expectations before surgery and implementing strategies to further reduce leg numbness may enhance overall patient satisfaction and outcomes.
