STUDY DESIGN Biomechanical analysis of a novel prosthesis based on the physiological curvature of endplate was performed. OBJECTIVE To compare the biomechanical differences between a novel prosthesis based on the physiological curvature of the endplate and the Prestige LP prosthesis after cervical disc replacement (CDR). SUMMARY OF BACKGROUND DATA Artificial disc prostheses have been widely...

Anterior cervical discectomy and fusion (ACDF) is currently considered the definitive surgical treatment for symptomatic single-level degenerative disc disease (DDD) of the cervical spine. The goals of ACDF are to relieve pressure on the spinal nerves (decompression) and to restore spinal column alignment and stability. Resolution of pain and neurological symptoms may be expected in more than 8...

Rationals for total disc replacement Dynamic reconstruction of a degenerative “functional spinal unit” (FSU) is a rapidly growing field in spinal surgery. So far anterior cervical discectomy and fusion (ACDF), first described by Smith and Robinson and by Cloward in the 1950s, is the most common surgical procedure proven successful in the treatment of symptoms caused by cervical degenerative dis...

Which has failed at least 6 weeks of conservative nonoperative treatment, including active pain management program or protocol, under the direction of a physician, with pharmacotherapy that addresses neuropathic pain and other pain sources AND physical the...

BACKGROUND A feasibility trial was conducted to evaluate the initial safety and clinical use of a next-generation artificial cervical disc (M6-C artificial cervical disc; Spinal Kinetics, Sunnyvale, CA) for the treatment of patients with symptomatic degenerative cervical radiculopathy. A standardized battery of validated outcome measures was utilized to assess condition-specific functional impa...
