Abstract:
Objective To discuss surgical techniques during microendoscopic discectomy (MED) in the treatment of lumbar intervertebral disc herniation complicated with posterior longitudinal ligament calcification and osteophyte of posterior lumbar border. Methods The self-made arc-like annular knife and L-shape introducer were used during MED in the treatment of 115 patients. Results All the patients were followed for 12~30 months (mean, 22 months). According to the MacNab criteria, excellent or good results were achieved in 109 patients, fair results in 5 patients, and poor in 1, the rate of excellent or good results being 94.8% (109/115 ). No ruptured spinal dura mater, nerve root injuries, or infection of intervertebral space occurred. No conversions to open surgery were required. Conclusions Use of self-made instruments and corresponding modified techniques during MED can effectively manage the problems of posterior longitudinal ligament calcification and osteophyte of posterior lumbar border, which broadens the surgical indication and improves the efficacy and safety.
