Title
(EN) BONE JOINT IMPLANTS
(FR) IMPLANTS D’ARTICULATION OSSEUSE
Abstract
(EN)
A bone joint implant (1) has a proximal part (120) for translational motion over the trapezium in a first carpometacarpal joint and a distal part (110) for intramedullary engagement in the first metacarpal bone. An articulating coupling (103, 121, 123) is for multi-axial motion with translational movement over a bone in one part (120) and rotation in the other part (110) about the articulating coupling (121, 103). A flange (105) extends radially and around the coupling to limit relative rotational motion of the proximal and distal parts about the coupling, and to provide resilience for contact between the proximal and distal parts. The flange has a contoured surface (101) matching an abutting surface (125) of the proximal part (122) upon articulation of the parts in use to extreme positions. The flange (105) is included in an insert (100) in a stem (111) of the distal part (110), the flange extending proximally of the stem (111) and prohibiting contact between the proximal part (120) and the stem (111) during articulation.

La présente invention concerne un implant d’articulation osseuse (1) ayant une partie proximale (120) pour le mouvement de translation sur le trapèze dans une première articulation carpométacarpienne et une partie distale (110) pour une entrée en prise au niveau intramédullaire dans le premier os métacarpien. Un accouplement d’articulation (103, 121, 123) sert au mouvement multiaxial avec un mouvement de translation sur un os dans une partie (120) et de rotation dans l’autre partie (110) autour de l’accouplement d’articulation (121, 103). Une collerette (105) s’étend radialement et autour de l’accouplement pour limiter le mouvement de rotation relatif des parties proximale et distale autour de l’accouplement, et pour fournir la résilience pour le contact entre les parties proximale et distale. La collerette présente une surface profilée (101) correspondant à une surface de butée (125) de la partie proximale (122) lors de l’articulation des parties dans l’utilisation dans des positions extrêmes. La collerette (105) est comprise dans un insert (100) dans une tige (111) de la partie distale (110), la collerette s’étendant de manière proximale à la tige (111) et empêchant le contact entre la partie proximale (120) et la tige (111) durant l’articulation.
