Apparatus and method for post-rotation correction of shoulder arthroplasty

摘要

A kit for implanting a glenoid component includes a retroversion glenoid component having a generally flat glenoid bone contacting surface defining a first plane. The component has a first offset peg extending away from the glenoid bone contacting surface, a concave articulating surface, an upper surface extending about the concave articulating surface and generally opposite to the glenoid bone contacting surface. The upper surface defines a second plane which is angled with respect to the first plane. The glenoid bone contacting surface defines a circular periphery with the centre peg centred within the circular periphery, and the nadir of the concave articulating surface located on the centre peg axis. A drill guide is configured to guide a drill in forming a bore in a scapula to receive the first offset peg.
