Abstract
BACKGROUND: Percutaneous endoscopic lumbar discectomy (PELD) is a relatively less invasive treatment for lumbar disc herniation (LDH). This study investigated the usefulness of a full-endoscopic system for PELD in lumbar ligamentum flavum hematoma (LFH) treatment. METHODS: Between May 2017 and Jun 2018, a total of five patients with leg pain due to LFH underwent surgery using a full-endoscopic system for PELD. A percutaneous endoscopic translaminar approach (PETA) was performed right above the LFH. Pathological examination of the hematoma capsule was performed in all cases. RESULTS: The mean age of the patients was 64 years; there were 3 male and 2 female patients. Leg pain improved immediately after operation in all cases. Intraoperative findings and pathological examination revealed that the synovium at adjacent facet joints was not involved. CONCLUSIONS: Full-endoscopic system is not only a safe and effective minimally invasive system for the treatment of lumbar LFH, but is also superior to acquire a correct diagnosis.
