Hip surgery systems and methods

Abstract

Orthopedic systems and methods are provided for use in preparing joints for implants. Specifically, hip preparation systems and methods are disclosed which can include a surgical orientation device. The hip preparation systems and methods can be used, for example, to orient the hip during the procedure, determine the orientation of an anatomical plane or planes, and orient a prosthetic component or components.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation from U.S. patent application Ser. No. 12 / 557,051, filed Sep. 10, 2009, which is incorporated in its entirety by reference herein, which claims benefit under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 61 / 191,603, filed Sep. 10, 2008, and to U.S. Provisional Patent Application No. 61 / 226,668, filed Jul. 17, 2009, each of which is incorporated in its entirety by reference herein.BACKGROUND OF THE INVENTIONS[0002]1. Field of the Inventions[0003]The present application is directed to systems and methods for joint replacement, in particular to systems and methods for hip joint replacement which utilize a surgical orientation device or devices.[0004]2. Description of the Related Art[0005]Joint replacement procedures, including hip joint replacement procedures, are commonly used to replace a patient's joint with a prosthetic joint component or components. Specifically, the hip joint often requi...

AI Technical Summary

Benefits of technology

The patent text describes an apparatus and method for accurately positioning components of prosthetic joints during orthopedic procedures without complicating the procedures, crowding medical personnel, or burdening the patient or healthcare facility with expensive navigation systems. The apparatus includes a reference post, a coupling device, and an orientation sensor for measuring the position and orientation of the patient's hip joint. The method involves measuring the reference distance from the reference device to anatomical landmarks on the patient's hip and moving the patient's hip joint to a selected position to accurately position the patient relative to a fixed reference frame. The technical effects of the patent text include improved accuracy in positioning components of prosthetic joints and reduced complexity of the procedures.

Problems solved by technology

Accordingly, there is a lack of devices, systems and methods that can be used to accurately position components of prosthetic joints without overly complicating the procedures, crowding the medical personnel, and / or burdening the physician or health-care facility with the great cost of complex navigation systems.
