Abstract: An orthopedic device includes a patient-specific acetabular guide that can be used for preparing an acetabulum of a patient to receive an acetabular implant. The acetabular guide has a dome-shaped body with a peripheral annular rim and an outer three-dimensional surface configured to match an acetabulum of a specific patient's hip joint from three-dimensional medical images of the patient's hip joint. A patient-specific registration guide is removably attached to the peripheral rim and has a longitudinal bore defining a patient-specific alignment axis with an alignment orientation configured for guiding an acetabular implant for the patient. The registration guide has a patient-specific undersurface configured to mate with a corresponding surface of periacetabular surface of the acetabulum of the patient.

Abstract: A method and tool for driving a bit. The tool includes a handle extending along a longitudinal axis between a first end and a second end. The handle can be in a first configuration to provide a first drive ration.

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: A method of determining an optimal position of a glenoid implant. The method includes identifying a center point of a patient's glenoid fossa based on an image of the patient's glenoid fossa; determining the optimal position of the glenoid implant based on the location of the center point relative to a medial point of the patient's scapula; and selecting orientation of an alignment pin based on the determined optimal glenoid implant position such that the glenoid fossa will be prepared to receive the glenoid implant at the optimal position when the glenoid fossa is prepared with a cutting device or guide coupled to the alignment pin.
