    摘要: A prosthesis for use in maintaining an interspinal space is disclosed. The prosthesis may be provided as first and second substantially symmetrical halves. The first and second halves may each have a coupling portion and a process portion. The coupling portions allow the separate halves to be separately fit within the interspinal space and then connected to form a single prosthesis, eliminating the need for cutting connecting ligaments to allow insertion of the prosthesis. Various connection and locking arrangements are disclosed to maintain the halves engaged with each other and the interspinal space.

    摘要: An intervertebral implant (1), having an upper section (10) provided with a ventral side area (11), a dorsal side area (12), two lateral side areas (13,14), a top apposition surface (15) and a bottom surface (16); and a lower section (20) provided with a ventral side area (21), a dorsal side area (22), two lateral side areas (23,24), a bottom apposition surface (25) and a top surface (26). The two sections (10;20) are moveable in relation to each other by means of two joints (38;39) arranged between the two sections (10;20), the two joints (38;39) are realised by an upper joint section (31) connected to the upper section (10), a central joint section (32) and a joint section (33) connected with the lower section (20). One of the external joint sections (31;33) comprises at least one concave sliding surface (58) rotation-symmetrical with regard to a swivel axle (3;4); and the other of the external joint sections (31;33) comprises at least one convex sliding surface (55) rotation-symmetrical with regard to the other swivel axle (3;4).
