Five-year results of cervical disc prostheses in the SWISSspine registry.

Background: The Swiss Federal Office of Public Health demanded a nationwide HTA-registry for cervical total disc arthroplasty (TDA), to decide about its reimbursement. The goal of the SWISSspine registry is to generate evidence about the safety and efficiency of cervical TDA.

Materials And Methods: Three hundred thirty-two cases treated between 3.

Sagittal alignment and kinematics at instrumented and adjacent levels after total disc replacement in the cervical spine.

Background: The purpose of the study was to report radiological outcomes after total disc replacement (TDR) in the cervical spine through a 24 months follow-up (FU) prospective study with a special focus on sagittal alignment and kinematics at instrumented and adjacent levels.

Materials And Methods: Thirty-two patients, who sustained one-level TDR with a ball-and-socket arthroplasty (Discocerv(™) implant, Scient'x/Alphatec Spine, USA) were consecutively included in the study. Clinical (visual analogical scale and neck disability index) and radiological parameters were measured preoperatively and postoperatively at 3/6 months, 1-year and 2-year FU.
