Factors Influencing Recurrence Rates and Surgical Outcomes in Lumbar Microdiscectomy: A Retrospective Study of 130 Patients in Turkey.

BACKGROUND Lumbar disc herniation surgery, specifically lumbar microdiscectomy, shows recurrence in 3-24% of patients, necessitating potential re-operations. This study focuses on the outcomes and recurrence causes in 130 cases of lumbar disc herniations. These cases were managed by a single surgeon at a single center, offering a unique perspective on a common issue in neurosurgery. MATERIAL AND METHODS The study involved 130 patients treated for lumbar disc herniations. Analysis considered various factors: age, sex, symptoms, surgical level, complications, pre- and postoperative pain levels, and quality of life indices. RESULTS Of the 130 cases analyzed, all underwent initial surgery by the same surgeon or sought treatment from this surgeon after recurrence. Inclusion criteria were based on radiologic and clinical indications for re-operation. The demographic split was 76 males (56.4%) and 54 females (43.6%). A notable finding was a higher recurrence rate in males and patients under 45 years, although the sex difference was not statistically significant. The average age was 47.5 years. Significant changes were noted in the Oswestry Disability Index (ODI) levels during follow-ups (P<0.001). CONCLUSIONS This study underscores the effectiveness of lumbar microsurgery in treating recurrent lumbar disc herniations. Techniques such as medial facet utilization and laminectomy border expansion show promise. However, determining instability rates requires long-term patient follow-up. Our findings contribute valuable insights into surgical approaches and patient outcomes in recurrent lumbar disc herniation cases.
