PROBLEM TO BE SOLVED: To provide an intervertebral implant which is equipped with a fixing plate which is clamped solidly.SOLUTION: An intervertebral implant 100 for fusion between two vertebral bodies of the spinal column fits so that it intervenes between two adjoining vertebral bodies of a patient and has a fusion cage 1 which extends from a rear side to a front side and a fixing plate 2 which has at least one passage 16. The fusion cage and the fixing plate include cooperation feature parts 8, 10, 17, 19, 21 for fastening the fixing plate on the front side of the fusion cage. The cooperation feature parts include restraint means 8, 17 and pivot means 10, 19. The pivot means is arranged so that they guide the rotation of the fixing plate on the fusion cage around a pivot X. This rotation transforms the implant from a first arrangement configuration where the fixing plate can be displaced to the posterior-anterior direction freely to the fusion cage to a second arrangement configuration where the displacement of the fixing plate in the posterior-anterior direction to the fusion cage is stopped by the restraint means.
摘要:
An adjustable intervertebral implant (100) for implantation into a patient's spine in-between first and second adjacent or neighboring vertebrae. The implant may include one or more of the following features: (i) inner (110) and outer (115) members coupled by a radiographically imageable expansion ring (130), (ii) detachable endplates (120,125) coupled to the implant via a polygonal press-fit coupling interface that accommodate a range of lordotic endplates to be applied to the implant using any surgical approach, (iii) an interference pre-loaded set screw (160) for selectively locking the height of the construct, (iv) a radiographically imageable marker (180) for determining the expansion of the implant, and (v) an asymmetric thread coupling (133,190) between the expansion ring and the inner member.

PROBLEM TO BE SOLVED: To improve the clinical status of a patient while ensuring the mobility of the patient without performing fusion surgery.SOLUTION: A device, designed to treat facet joint dysfunctions, comprises: a prosthesis body having a first surface and a second surface; a long retainer configured to maintain the position of the prosthesis body in relation to a facet joint; and at least one holder interface capable of holding the long retainer by allowing it to penetrate through the holder interface. The long retainer is provided with a flexible wire or cable (96) extending and penetrating the holder interface, which includes a first portion configured to articulate with a first lateral face of the facet joint and a second portion configured to articulate with a second lateral face of the facet joint.
