Abstract: A patient-specific acetabular guide can be used for preparing an acetabulum of a patient to receive an acetabular implant. The acetabular guide includes a patient-specific engagement surface designed to be complementary and mateable with a corresponding surface of the patient's pelvic anatomy. The acetabular guide is designed during a pre-operative plan for the patient by a three-dimensional reconstruction of the anatomy of the patient using two-dimensional medical images. The patient-specific engagement surface has a first portion mateable with a portion of the acetabulum of the patient. The acetabular guide includes a guiding element that extends from the acetabular guide opposite to the first portion of engagement surface. The guiding element defines a bore designed to be oriented along an alignment axis for an acetabular implant when the acetabular guide is engaged to the acetabulum.

Abstract: Disclosed is a system for engaging and holding a prosthesis both axially and rotationally relative to an inserter assembly. The inserter assembly can engage an acetabular prosthesis in a selected position, such as axially, with a first portion and then or subsequently engage the acetabular prosthesis with a second portion in a rotationally fixed manner. The acetabular prosthesis can then be inserted into a prepared acetabulum according to a disclosed method with the inserter assembly. The inserter assembly can then be removed from the acetabular prosthesis to allow for reduction of a femur.

Abstract: An implant for a femoral head of a patient. The implant includes a shell implantable on the femoral head of the patient and correcting a defect of the femoral head. The shell is designed preoperatively to have a patient-specific first surface for articulation with the patient's acetabulum and a patient-specific periphery mateable with a periphery of the defect. The shell caps the defect and the first surface of the shell is continuous to a remaining healthy surface of the femoral head. The defect can be a bone defect, a cartilage defect or a combination thereof.

Abstract: A surgical kit for preparing a joint surface to receive an implant includes a patient-specific guide for a joint surface. The patient-specific guide has a patient-specific surface complementary to a surface of the joint for nesting engagement, and a guiding element oriented along a patient-specific alignment axis. The alignment axis is determined during a preoperative plan of the specific patient for implant alignment. The kit includes a guiding tool couplable to the guiding element of the patient-specific guide and a three-dimensional orientation device removably couplable the guiding tool for intra-operative calibration, such that, after calibration, the orientation device can be removably coupled to a shaft of a surgical instrument to align the shaft along the alignment axis.

Abstract: A modular femoral hip implant trialing system. The system generally includes a proximal body, a fastener, and a fastener retention member. The proximal body includes a proximal bore, a tapered distal bore, and a passageway connecting the proximal bore to the distal bore. The proximal bore, the distal bore, and the passageway are aligned along a first axis. The fastener includes a head in the proximal bore and a stem in the distal bore, the fastener is aligned along the first axis. The fastener retention member is positioned in the proximal bore and is operable to retain at least a portion of the fastener within the proximal bore.
