THE RATIO OF RECURRENT DISC HERNIATIONS IN POSTERIOR THORACIC AND LUMBAR FUSION SURGERIES

Özet

Objective: The aim of our study is to evaluate the ratio of recurrent disc herniation in posterior thoracic-lumbar fusion surgeries. Materials and Method: We evaluate the ratio of recurrent disc herniation in posterior thoracic-lumbar fusion surgeries. The patient files and radio-diagnostic images were inspected retrospectively. Simple microdiscectomies lateral and anterior thoracic-lumbar stabilization surgeries were excluded. Results: One hundred ninety one patients were included in the study. Mean age of the study group was 56.3 ± 14.2 years. M/F was 48.2 / 51.8. Mean age was 53.6 years for males, and 58.8 years for women (p=0.06). Most frequent diagnosis was stenosis (n=117, 61.3 %), and recurrence was present in 14.7 % of the cases (n=28). Revision operation was performed in 6.8 % of patients. The comparisons between genders revealed that stenosis rates were higher in females, and fracture rates were higher in males (p=0.003). However, rates of revision operations were similar between males and females (p=0.445). Most frequent level of recurrent disc herniation were L4-L5 (78.57 %). Conclusions: It is spectacular that the ratio of recurrent disc herniation is more than listhesis and fracture surgeries in posterior thoracic-lumbar instrumentation surgeries.
