Abstract: Porous regions are formed using selected additive manufacturing techniques. The porous regions can assist in fibro-inductive regions and/or osteo-inductive regions. A prosthetic member can be formed completely with the additive manufacturing technique and/or the additive manufacturing techniques can be used to form an augment portion that is added to the prosthetic member formed separately.

Abstract: A method for preparing a femoral neck for receiving a neck implant includes resecting a femoral head from a femoral neck of a patient according to a pre-operative patient-specific plan. The method also includes removing only cancellous bone from the femoral neck and proximal femoral bone of the patient using a patient-specific broach. The patient-specific broach has a three-dimensional cutting surface matching as a negative mold a cortical/cancellous bone interface surface of the femoral neck of the patient.

Abstract: A suture construction and method for forming a suture construction is disclosed. The construction utilizes a suture having an enlarged central body portion defining a longitudinal passage. First and second ends of the suture are passed through first and second apertures associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes constriction of the longitudinal passage, thus preventing relative motions of the captured portions of the suture.

Abstract: A pelvic implant includes a first surface including a recess configured for receiving a portion of a flange of an acetabular cage and a patient-specific second surface opposite to the first surface. The patient-specific second surface is preoperatively configured from a three-dimensional digital image of a pelvis of a patient to mate and closely conform to a corresponding surface of the pelvis under the flange in only one position.

Abstract: A method for inserting an acetabular implant into the acetabulum of a patient. The method includes engaging a patient-specific surface of acetabular alignment guide to a complementary rim surface and periacetabular area of a patient. A plurality of alignment pins are inserted through corresponding alignment apertures of the acetabular alignment guide and into the periacetabular area of the patient. The acetabular alignment guide is removed without removing the alignment pins from the patient. An alignment adapter is coupled to an acetabular inserter over the alignment pins and an acetabular implant is implanted using the acetabular inserter.
