Objective To investigate the clinical value of microendoscopic disectomy for the treatment of lumbosacral disc herniation(LDH). Methods Microendoscopic disectomy (MED) technique was used to remove the nucleus and decompress the narrowed nerve root canal through an incision of 1.6 cm in length under the guidance of the 'C' arm X-ray machine. Results Eighty-two patients with LDH underwent MED were followed up for 5 months. Eighty patients were evaluated as excellent, two as good according to the Macnab Scale. Conclusion The microendoscopic disectomy can clearly expose the intervertibra and the nerve root, has little influence on the stability of the posterior structure of the spine, and can keep the spine intact.So the microendoscopic disectomy is a safe and an effective technique.
