Glenoid components with asymmetric fixation points are provided. Also, methods and devices are provided for the optimization of shoulder arthroplasty component design through the use of medical imaging data, such as computed tomography scan data. The methodology may improve the understanding of glenoid anatomy through the use of medical imaging data and 3D modeling, and for glenoid components that exploit this methodology. The methodology provides for how anatomical features change based on the specific location in the glenoid. The methodology can optimize loading and fit at the bone-device interface. Asymmetrical glenoid components are provided with significantly improved initial fixation.

An intervertebral implant with a support portion (1.1) and a proximal contact portion (1.3) adjoined thereto in the longitudinal direction, is better adapted, as an intervertebral implant, to the contours of the lower and upper sides of the vertebrae that are spaced apart by the implant. An upper side (1.6) and a lower side (1.7) of the implant are configured symmetrically relative to a horizontal center plane (L-Q). In particular a height of the support portion between the transition (U) thereof to the contact portion (1.3) and a distal end face (1.2) facing away from the contact portion (1.3) are greater than the height at the transition (U) and at the distal end face (1.2).

One embodiment of the present disclosure relates to a glenoid implant with a body and a keel. The body includes an articulation surface and a bone facing surface, and the keel has a depth that extends from the bone facing surface to a free end of the keel. The keel has a first length and a first width, both measured in a plane perpendicular to a direction of the depth. The first length is measured perpendicular to the first width and is defined by a first distance from an inferior end of the keel to a superior end of the keel. The first width is measured at a first location adjacent to the inferior end, and the keel has a width dimension along a first portion of the keel from the first location to the superior end that tapers from the first location toward the superior end.

A subtalar implant for arthroereisis of the talocalcaneal joint. The implant is intended to be inserted into the talocalcaneal joint via its lateral orifice and has an oblong shape that extends longitudinally along an axis of insertion of the implant. The implant includes: a head with the shape of a cone of revolution centred on the axis of insertion; an anchoring thread; and a rod having the shape of a cylinder of revolution. The rod has, on its surface, the anchoring thread and being configured to be inserted up to the axis of rotation of the talocalcaneal joint. The head has, on its radially outer surface, a retaining element for retaining the implant in rotation about the axis of insertion, the retaining element exerting retention against a colonising tissue.

An anchor for an implantable device for arthroplasty can include a hollow anchor body defining an interior cannula space. A slot can extend along a length of the anchor body. The slot can provide an opening from the interior cannula space to an exterior of the anchor body. The slot can have a slot width that is smaller than an internal width dimension in the interior cannula space. The anchor can also include a rounded edge at a transition between the slot and at least one of an interior surface of the anchor body or an exterior surface of the anchor body.
