ALIGNMENT DEVICES AND METHODS

摘要

Embodiments of the invention include devices and methods for implanting arthroplasty devices. Some embodiments include designs that allow for use of x-ray images as the only images used to fully and accurately preoperatively and intraoperatively size and align arthroplasty device components and prepare all necessary tissue.

主权项

1. A femoral implant alignment guide for implanting a femoral component in a patient, comprising:
a body configured to be placed on a distal end of a femur and be aligned on an axis from between the patient's femoral condyles through the patient's hip center, the body including: an elongated resection aperture with a major axis substantially perpendicular to the axis through the patient's hip center when the body is aligned on the axis through the patient's hip center, and an offset portion that is configured to extend to a point in a coronal plane of the patient that is shared with the patient's greater trochanter when the body is aligned on the axis through the patient's hip center.
