Abstract:
Objective To assess the clinical application of microendoscopic discectomy (MED) system in the treatment of 36 cases of special lumbar disc herniation (LDH). Methods Laminectomy and decompression, and removal of fractured end plate or calcified herniated discs were performed by MED using self-made bone chisel, osteotome and L-shaped osteotome. Results Intraoperative dural laceration occurred in 2 cases, and no conversions to open surgery were required. Follow-up observation ranged (3～12) months (mean, 9.5 months). According to Macnab criteria, 28 patients had excellent, 5 had good, 2 had fair, and 1 had poor outcomes, with good or excellent results in 91.7% (33/36) of the patients. Conclusions MED may be carried out in patients in side position. Calcified herniated discs and fractured end plate can be excised by MED with self-made tools.
