Unilateral biportal endoscopic discectomy versus percutaneous endoscopic lumbar discectomy in the treatment of lumbar disc herniation: a retrospective study.

Background: Unilateral biportal endoscopic discectomy (UBE) is a rapidly growing surgical method that uses arthroscopic system for treatment of lumbar disc herniation (LDH), while percutaneous endoscopic lumbar discectomy (PELD) has been standardized as a representative minimally invasive spine surgical technique for LDH. The purpose of this study was to compare the clinical outcomes between UBE and PELD for treatment of patients with LDH.

Methods: The subjects consisted of 54 patients who underwent UBE (24 cases) and PELD (30 cases) who were followed up for at least 6 months.

Objective: To evaluate the clinical results of anterior cervical discectomy and reconstruction with a self-locking cage and internal fixation with short segmental plate for multilevel cervical spondylotic myelopathy.

Methods: From January 2012 to June 2015, a total of 106 patients received anterior cervical discectomy and reconstruction with a self-locking cage and internal fixation with short segmental plate were followed up. There were 71 males and 35 females, aged from 42 to 74 years old with an average of(55.
