Abstract
The present invention relates generally to the field of orthopedics, and more particularly to a pelvic referencing guide and methods of using the guide in orthopaedic surgery, specifically total hip arthroplasty.
Claims14
A method of determining the orientation of a patient's pelvis when the patient is in a lateral decubitus position, the method comprising the steps of:
- (a) using a pelvic referencing guide comprising;
- a body portion having a planar patient facing surface, a first transverse surface that extends away from and transverse to the patient facing surface and on which reference mark is provided, and a second transverse surface that extends away from and transverse to the patient facing surface and parallel with the first transverse surface, the second transverse surface including a second reference mark which is aligned with the reference mark on the first transverse surface such that the reference marks on the first and second transverse surfaces can be simultaneously aligned with the transverse pelvic line on the patient's skin, the line extending between an underlying right posterior superior iliac spine and left posterior superior iliac spine, and an inclinometer for indicating the orientation of the transverse pelvic line in at least one vertical plane;
- (b) positioning the planar patient facing surface of the guide against the patient's skin such that the reference mark is aligned with a part of the transverse pelvic line;
- and
- (c) assessing using the inclinometer the orientation of the transverse pelvic line in at least one vertical plane.
A pelvic referencing guide for use in determining the orientation of a patient's pelvis when the patient is placed in a lateral decubitus position, the guide comprising a body portion having a planar patient facing surface, a reference mark for aligning with a transverse pelvic line on the patient's skin which extends between an underlying right posterior superior iliac spine and left posterior superior iliac spine, and an inclinometer for indicating the orientation of the transverse pelvic line in at least one vertical plane, wherein the body portion includes
- a first transverse surface that extends away from and transverse to the patient facing surface and on which the reference mark is provided, and
- a second transverse surface that extends away from and transverse to the patient facing surface and parallel with the first transverse surface, the second transverse surface including a second reference mark which is aligned with the reference mark on the first transverse surface such that the reference marks on the first and second transverse surfaces can be simultaneously aligned with the transverse pelvic line.
The guide of claim3, wherein the guide includes a handle.
