Spine arthroplasty: a historical review.

摘要: Degenerative disc disease is one of the most frequently encountered spinal disorders. The intervertebral a complex anatomic and functional structure, which makes development an efficient reliable artificial challenge. Not only function arduous to reproduce, but there are important consequences associated with conception choice materials that will have bear loads. Biochemical problems complicated things even more. Two different principles been applied in realisation discal replacement: metallic and/or polyethylene prosthesis allowing mainly mobility or enabling reproduction viscoelastic properties. Of course some devices attempt combine both principles. In this paper we try present, chronological order, overview designs published literature as well patents granted field. very fact such long list implants, based on highly varied principles, has proposed, few reached level animal models, let alone human implantation, clearly demonstrates how challenging task designing replacement is. Proper randomized controlled trials now way, should help assessing efficacy real place spine arthroplasty treatment Only then surgery join successful joint replacements.
