BACKGROUND: The aim of this study is to compare the outcome of the minimally invasive transmuscular approach using a tubular retractor system (Metrx) with the conventional microsurgical standard approach (CM) for microsurgical treatment of lumbar disk herniation.
METHODS: This is a prospective randomized controlled study with a 1:1 distribution of patients in CM and Metrx study groups. Two hundred and twenty-seven (117 CM and 110 Metrx) patients were included. The primary outcome parameters are postoperative pain intensity reduction, length of hospitalization, postoperative quality of life, and daily life performance based on the standardized questionnaires: Visual Analog Scale (VAS), 36-Item Short Form Survey (SF-36), Oswestry Disability Index (ODI), and Prolo scores. The secondary outcome parameters are intraoperative variables: surgery duration, blood loss, and fluoroscopy dose.
RESULTS: There were no significant statistical differences in the primary outcome measures between the two groups with respect to postoperative pain relief (median VAS pre-op to 3 months post-op for sciatica: 9-2 [CM] vs. 8-2 [Metrx]; for lumbago: 7-2.5 [CM] vs. 6-3 [Metrx]), the length of hospitalization (median of 5 days), or the frequency of occupational reintegration after 3 months (59.1 vs. 60.7%).
CONCLUSION: The microsurgical therapy of lumbar disk herniation via a Metrx approach is a safe and effective treatment option and is equivalent to the CM approach.
