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.
Claims18
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 reference mark for aligning with a 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 method for guiding an operator in altering an orientation a pelvis of a patient for subsequent insertion of a pelvic implant, comprising the steps of:
- (a) placing a patient in a lateral decubitus position;
- (b) using a pelvic referencing 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, 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;
- (c) 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;
- (d) assessing using the inclinometer the orientation of the transverse pelvic line in at least one vertical plane, and optionally
- (e) repositioning the patient to a position wherein the orientation of the transverse pelvic line is vertical in the 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.
