OBJECTIVE Discectomy as a treatment for herniated lumbar discs results in outcomes after surgery that are not uniformly positive. Surgeons face the dilemma between limited nucleus removal which is associated with a higher risk of recurrence, or more aggressive nucleus removal which may lead to disc height loss and persistent back-pain. annulus closure devices may allow for the benefits of limit...

PURPOSE The purpose of this study was to evaluate perioperative complications of lumbar discectomy with or without bone-anchored annular closure device (ACD) implant in patients at high risk of recurrent disc herniation. METHODS This was a post hoc analysis of a randomized controlled trial that compared outcomes of lumbar discectomy with or without additional placement of an ACD. Patients pre...

Percutaneous endoscopic discectomy (PED) is a minimally invasive technique for the treatment of lumbar foraminal or extraforaminal and foraminal disc herniations that represent up to 11% of all lumbar herniated discs (1-4) Another study defined that farlateral disc herniations, constituting 7% to 12% of all disc herniations, typically migrate cranially as they extended laterally, foraminally, a...

The concept of minimally invasive spinal surgery embodies the goal of achieving clinical outcomes comparable to those of conventional open surgery, while minimizing the risk of iatrogenic injury that may be incurred during the exposure process. The development of microscopy, laser technology, endoscopy, and video and image guidance systems provided the foundation on which minimally invasive spi...

  The authors report experiences of anterior cervical discectomy without fusion for cervical disc disease. A series of 17 patients were operated on using a modified Smith-Robinson technique. Radical discectomy and extensive removal of posterior osteophytes were performed without bone graft. Fifteen out of the 17 cases were operated on at a single level. Three discectomies were perform ed a...

bilateral vocal cord paralysis is a rare and preventable complication of anterior cervical discectomy and fusion. herein, we report a fatal case of bilateral vocal cord paralysis after anterior cervical discectomy and fusion (acd/f). a 65-year-old man with cervical spine trauma and anterior cord syndrome, following car overturn presented to our emergency department. the patient had c6-t10 prola...

BACKGROUND Conventional anterior cervical discectomy with fusion is thought to require postoperative neck immobilization for the promotion of bony fusion. Rigid internal fixation with anterior cervical plates may decrease graft-related complications and provide immediate stability. This stability may obviate postoperative external immobilization. METHODS This report reviews one surgeon's expe...
