A collar arranged to couple to a prosthetic component for implantation at the end of a long bone, the prosthetic component having a distal portion arranged to couple to the bone and a proximal neck portion arranged to couple to an articulation component. The collar comprises a plate including a neck hole to receive a neck portion, such that the collar can rotate about the neck portion. The collar further comprises a plurality of attachment portions for coupling the plate to bone fragments or soft tissues. The collar is lockable to the neck portion to prevent further rotation. A prosthesis comprising a combination of a collar, a prosthetic component and an articulation component, and a surgical method of using the collar are also disclosed.

Rotatable collar for a prosthesis

An implant (), prosthesis and method of use are described. The implant comprises an articulation component () having a bearing surface () and a reverse surface () arranged to couple to a proximal neck portion () of an arthroplasty implant () coupled to a bone. A collar () is arranged to couple to the reverse surface of the articulation component. The collar defines a neck hole () arranged to pass around the coupling between the articulation component and the proximal neck portion of the arthroplasty implant. The collar and the articulation component comprise complementary coupling features to secure the collar to the articulation component. The collar further comprises a plurality of attachment portions () to couple the collar to bone fragments or soft tissues. The prosthesis comprises the implant and an arthroplasty implant having a distal portion arranged to be coupled to an end of a long bone and a proximal neck portion.

An arthroplasty plate and method of use to repair a fractured end of a bone are described. The arthroplasty plate comprises a fixation plate arranged to be secured to a surface of a bone and a connector assembly comprising a barrel extending from the fixation plate and having a bore which opens through the fixation plate. A connector rod is arranged to slide within the bore of the barrel. An articulation component comprises a bearing surface coupled to or arranged to couple to an end of the connector rod which extends from the barrel away from the fixation plate. The connector assembly incorporates an adjustment mechanism arranged to cause the connector rod to slide into or out of the barrel and a locking mechanism arranged to lock the position of the connector rod within the barrel to rigidly space the articulation component apart from the fixation plate.
