US 2014/0180296 A1 · DEVICES AND METHODS FOR HIP REPLACEMENT

Abstract

Devices and methods for use in hip replacement surgery can incorporate computer models of a patient's acetabulum and surrounding bone structure, a first patient-specific jig designed from the computer model and configured to correspond to a final installation position and orientation of a prosthetic him implant, a second patient-specific jig, also designed from the computer model, configured to refine the procedure, if necessary, following use of the first patient-specific jig, and/or a third patient specific jig, designed from the computer model, configured to refine the procedure, if necessary, following use of the first and second patient-specific jigs, allowing the surgeon to properly position and orient the hip prosthesis. Also shown and described are novel devices for implanting an acetabular cup.

Dependent claims

A device for use in joint replacement surgery, the device comprising:

a patient-specific jig having a body formed using three dimensional data corresponding to a bone structure of a patient, the body having a proximal end and a distal end and being configured to be positioned at against the bone structure of the patient at a joint location, the body including a first alignment member, a second alignment member, and a third alignment member, each alignment member positioned at respective locations adjacent the proximal end of the body and oriented corresponding to the three dimensional data of the bone structure, the alignment members configured to position and orient the body with respect to the bone structure to indicate information to a surgeon corresponding to a final installation position of a prosthesis implant to be secured to the bone structure of the patient according to the three dimensional data.
