Study to Assess the Safety and Performance of the OrtoWell® Distractor in Patients Undergoing Spinal Surgery

This is a Prospective, single-arm, multi-center, observational, post-market clinical follow-up study The OrtoWell® Distractor System (CE marked) is a device intended for separating and holding apart vertebral bodies in the spinal column, to facilitate removal of damaged discs, and implantation of disc prostheses or spinal cage prostheses, as well as for repositioning the vertebral bodies following implantation of disc or cage prostheses The OrtoWell® Distractor System will be used in patients undergoing anterior or lateral spinal surgery, where separation of vertebrae is required, including corpectomy, insertion of disc prosthesis, insertion of an anterior lumbar interbody fusion (ALIF) cage, and tumor surgery The study will enroll up to 32 patients in Germany that require one of the above listed intervention except the patients with a known osteoporosis Study subjects are expected to participate for approximately 30 days following the surgery. Participation will involve a screening period, surgery and scheduled follow-up assessment at 30 days post implant
