Patent number: 9095448Abstract: A method of aligning an alignment guide relative to a reamed acetabulum of a patient is provided. The method includes the step of manipulating an alignment guide comprising a shaft having a longitudinal axis and a guide arm having a first portion, a second portion and a third portion, the first portion attached to the shaft and configured to be rotatable about a first axis substantially perpendicular to the longitudinal axis, the second portion extending from the first portion at a first predetermined angle along a second axis, and the third portion extending from the second portion at a second predetermined angle. The guide arm is rotated about the first axis relative to the shaft. A cup or trial is attached to the distal end of the shaft and positioned to contact the reamed acetabulum. The third portion of the guide arm is then oriented with respect to the long axis of the patient and the surface of the table on which the patient is positioned.Type: GrantFiled: May 4, 2010Date of Patent: August 4, 2015Assignee: DEPUY INTERNATIONAL LIMITEDInventors: Alec Birkbeck, Robert Freeman, Gary Moore, Steven Gowers

Patent number: 9084687Abstract: An orientation guide comprising a housing arranged to couple to a surgical instrument. In one embodiment the orientation guide further comprises first and second indicators (22, 26). The first indicator (22) is pivotally coupled to the housing (20) such that the first indicator (22) can rotate relative to the housing (20) about a first axis (24) to maintain its angular position about the first axis (24) relative to a vertical axis irrespective of movement of the housing (20). The second indicator (26) surrounds the first indicator (22) and is pivotally coupled to the housing (20) such that the second indicator (26) can rotate relative to the housing (20) about a second axis (32) orthogonal to the first axis (24) to maintain its angular position about the second axis (32) relative to the vertical axis irrespective of movement of the housing (20).Type: GrantFiled: December 18, 2009Date of Patent: July 21, 2015Assignee: DEPUY INTERNATIONAL LIMITEDInventors: Ivan Green, Robert Freeman, Steven Gowers
