Patent number: 8603180Abstract: An acetabular device includes a patient-specific acetabular alignment guide including a bone engagement surface. The bone engagement surface has a first portion configured and shaped to be conforming and complementary to an acetabular rim surface and a second portion configured and shaped to be conforming and complementary to a periacetabular area of an acetabulum of a patient. The acetabular alignment guide includes a plurality of guiding formations extending through the second portion for guiding a plurality of alignment pins therethrough. The bone engagement surface and the plurality of guiding formations are prepared from a three-dimensional model of the acetabulum of the specific patient reconstructed pre-operatively from a scan of the patient.Type: GrantFiled: May 19, 2011Date of Patent: December 10, 2013Assignee: Biomet Manufacturing, LLCInventors: John R.

Patent number: 8585770Abstract: An implant sleeve operable to center an implant at an implantation site. The implant sleeve includes a proximal end, a distal end, an annular sidewall, a mesh portion of the annular sidewall, and an interior area. The annular sidewall is between the proximal end and the distal end. The mesh portion defines a plurality of openings in the annular sidewall. The interior area is defined by the annular sidewall and is configured to receive a stem of the implant. A longitudinal axis of the implant sleeve extends along an axial center of the interior area.
