摘要:
Systems devices and methods are provided for aligning acetabular implants. A patient matched acetabular alignment tool is used to orient tools and implants intraoperatively. The patient matched acetabular alignment tool includes a mounting member and leg members which are configured based on the particular patient s anatomic landmark sites (e.g. acetabular bony landmarks). The leg members are attached to the mounting member and configured to connect with a respective anatomic landmark site to achieve a desired implant angle and axis. For example the leg members may form a tripod support base through which an acetabular shell may be inserted into the patient s acetabulum at desired angles of version and inclination. In some embodiments the leg members may be retractable and expandable with respect to the mounting member thereby providing a tool with reduced profile for inserting the device in the patient s soft tissue.
