Abstract: A guide device having a guide body including a bearing surface designed to bear in a glenoidal cavity of a scapula that has been prepared beforehand, the guide body including at least one through orifice emerging in the bearing surface, a reference member mounted on the guide body and including a bearing portion designed to bear on the anterior cortex of the scapula, and adjustment means arranged to adjust the position of the reference member with respect to the guide body so as to adjust the distance between the bearing portion and an axis of the through orifice.

Abstract: The intervertebral disc prosthesis comprises first and second plates (3, 4) designed to be attached on one of the two vertebrae adjacent to the intervertebral disc to be replaced, and a compression pad arranged between the first and second plates. Each plate comprises first attaching means including two attaching portions (14a, 14b) positioned symmetrically on either side of the anteroposterior median plane of said plate, second attaching means including two attaching portions (15a, 15b) positioned symmetrically on either side of a first plane inclined by an angle comprised between 50° and 70° relative to the anteroposterior median plane of said plate, and third attaching means opposite the second attaching means relative to the anteroposterior median plane and including two attaching portions (16a, 16b) positioned symmetrically on either side of a second plane inclined by an angle of approximately 90°, relative to the anteroposterior median plane of said plate.

Abstract: The invention relates to an intervertebral disc prosthesis (2) that comprises first and second rigid half-envelopes (3, 4) in the form of plates, each intended to be secured to one of the two vertebrae adjacent to the intervertebral disc to be replaced. The first half-envelope (3) includes a central tubular part (5) oriented towards the second half-envelope, while the second half-envelope (4) includes a central stud (6) having a cross-section smaller than that of the tubular part, said stud being oriented towards the first half-envelope and inserted in the tubular part. According to the invention, the intervertebral disc prosthesis further comprises a compression pad (7) disposed between the two half-envelopes, including in the space between the tubular part and the stud.

Abstract: The invention relates to an intervertebral disc prosthesis comprising two half-shells (7, 10) clasping a compression pad. According to the invention, the central part of one (10) of the two half-shells comprises a shaft (14) which faces the other half-shell (7), while the central part of said second half-shell (7) comprises a stud (13) which faces the first half-shell, said stud having a smaller cross-section than that of the shaft and being inserted therein. The sum of the lengths of the shaft (14) and the stud (13) is greater than the distance between the two half-shells (7, 10), the aforementioned compression pad being disposed between the two half-shells in the space between the shaft and the stud.
