Keywords:lumbar spine, discs herniation, microsurgical discectomy, endoscopic transforaminal microdiscectomy
Introduction. Method of endoscopic transforaminal microdiscectomy (ETMDE) has it’s own supporters and opponents. We decided to compare efficacy of ETMDE and open microdiscectomy (MDE).
Materials and methods. We analyzed treatment results in two groups of patients, similar in age, disease duration, hernia localization and size, severity of pain and radiculopathy. In 60 patients (group 1) ETMDE was performed, in 60 (group 2) — MDE. the Short-term results were evaluated in the period from 1 to 30 days after surgery.
Results. Positive results were achieved in both groups, respectively, in 91.7 and 88.4% patients. However, early reoperations were performed significantly more often in group 1 — in 8.3% patients than in the group 2 — in 1.5%. In group 1 unsatisfactory results were due to hernias migration in cranial or caudal direction, in group 2 — due to hernias middle position. Rehabilitation terms after ETMDE was almost 3 times less than after MDE.
Conclusion. ETMDE technique with proper patients selection and adequate surgeon’s experience as effective as MDE. Worse outcomes were due to hernias migration in cranial or caudal direction, but rehabilitation terms in general, three times less than after MDE.
