A semi-synthetic hybrid material having a pH from 7 to 7.4 includes an inorganic fraction and a cross-linked organic fraction. The method for producing this material, and osteosynthesis devices or implants made of semi-synthetic hybrid material are also described.

Implants, devices, and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant a first member, a second member, and an insert with a top surface and a bottom surface. The top surface couples to the first member and the bottom surface engages the second member. Kits and methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.

An acetabular joint prosthesis may be designed to replace an acetabular articular surface. The prosthesis can include an acetabular cup, an augment, and an augment-securing mechanism configured to secure the augment to the cup. The mechanism can be reconfigured between an unlocked configuration in which a slider is slidable along a guide feature and a locked configuration in which the slider or guide feature is in an expanded form such that the slider is fixed in place relative to the guide feature. An unlocked configuration may include the augment-securing mechanism allowing rotation between the augment and the cup, with the augment being securable to the augment in multiple rotational positions. Also, the prosthesis may be configured to facilitate actuation between the unlocked and locked configurations, including moving an instrument to the prosthesis in an access direction that is substantially perpendicular to a rim of the cup.

A Cloward-style cage device for anterior cervical fusion and fixation includes a body and a lateral stabilizer. The device uses the historical Cloward-style approach, and, as such, decompresses the interbody disc. The device can be used with a cylindrical drill bit to drill through the interbody disc to remove a portion of the interbody endplates to decompress a remaining portion of the interbody disc. The lateral portions of the endplates are generally preserved. The device has a cylindrical body formed of a mesh-like material, with lateral stabilizers.

The present invention relates to a stabilized ankle prosthesis configured for use in patients with compromised soft tissue in the ankle. The prosthesis of the present invention is a two-component design comprising a stabilizing lip configured to constrain movement in the general direction of compromised soft tissue.

Instruments, kits, and methods are disclosed for installing an implant spacer through an incision and down a surgical corridor. The instruments also serve to align a drill guide and align and insert a spacer stabilizer for stabilization of adjacent bone portions. An inserter instrument comprises an elongated guide bar body having a guide portion for aligning instruments with said spacer and for introducing a stabilizer to secure the spacer in a predetermined position between the bone portions. In preferred embodiments a stabilizer implant portion comprising a base wall separated by a retaining member by a web wall is introduced into a pre-bored hole in a bone and secured with a stabilizer anchor extending through a central bore. Included is a retractable graft block for securing graft material within an aperture of a spacer during insertion of the spacer.
