ABSTRACT:
A prosthetic socket implant installation apparatus and method combines holding, impacting, and aligning functions in a modular device. The apparatus comprises an installation tool that firmly engages a feature around the inner rim of a prosthetic socket implant so that the shell does not disengage during the installation process. An implant engaging arrangement on the installation tool is capable of extending to properly engage and hold implants in a broad range of sizes. The tool provides both axial and angular alignment references to facilitate the correct alignment of a prosthetic socket implant during installation. A mechanically isolated impacting rod slideably attaches within an opening along the longitudinal axis of the tool thus facilitating impact at the proper location and angle and allowing the alignment and impacting to be performed by one person. A method for installing a prosthetic socket implant includes retracting implant engaging means, engaging the socket, aligning the socket in the opening, installing the socket, and disengaging the socket.
