Abstract

Introduction: Lumbar spine instability is a significant cause of lower back pain, leading to limited mobility and daily activity impairment. Various surgical methods are indicated when conservative treatments fail. Among these, transforaminal lumbar interbody fusion (TLIF) using the Wiltse approach demonstrates several advantages, such as reduced muscle damage, minimized blood loss, faster recovery, ease of application, and low cost. Objective: To identify the clinical and imaging characteristics and evaluate the preliminary outcomes of surgical treatment for lumbar spine instability using transforaminal lumbar interbody fusion via the Wiltse approach. Subjects and Methods: A cross-sectional descriptive study was conducted on cases of lumbar spine instability treated with transforaminal lumbar interbody fusion at E Hospital from January 2023 to June 2023. Results: The male-to-female ratio was 1:1.5, with a mean age of 53 ± 11.77 years. The average disease duration was 23 ± 14.98 months. The most common level of instability was L4-L5, accounting for 86.7% of cases. Postoperative VAS scores for both back and leg pain, as well as ODI scores, were significantly lower than preoperative scores. Preoperative JOA score: 12.1 ± 2.61. The average surgery time was 140.67 minutes, with an average blood loss of 140.67 ml. The JOA recovery rate at 6 months post-surgery was good in 93.3% of cases and moderate in 6.7%. The bone fusion success rate was 100%. Conclusion: Transforaminal lumbar interbody fusion via the Wiltse approach shows promising preliminary results and is currently an optimal choice for the treatment of lumbar spine instability.
