A glenoid device for preparing a shoulder joint of a patient includes a reusable guide holder having a body between an upper surface and a lower surface and a bore passing through the body of the guide holder. The glenoid device also includes a patient-specific glenoid guide having a body with an upper and lower surface. The lower surface of the patient-specific glenoid guide is configured as a negative surface of a glenoid face based on preoperative image scans of the shoulder joint of the patient. The upper face of the patient-specific glenoid guide is configured to be coupled and contact the lower face of the guide holder, such that the bore of the guide holder is aligned along a patient-specific bore through the body of the patient-specific glenoid guide and along a corresponding alignment axis of the patient-specific glenoid guide.

Patient-specific glenoid guide with a reusable guide holder

A glenoid guide has an upper surface and a lower surface, wherein the lower surface is a patient-specific surface configured as a negative surface of a glenoid face based on a three-dimensional image of a shoulder joint of a patient reconstructed preoperatively from image scans of the shoulder joint of the patient. The glenoid guide includes an anatomic tubular drill guide extending from the upper surface along an anatomic alignment axis configured preoperatively with a patient-specific orientation and insertion location for guiding a glenoid implant into the glenoid face for anatomic shoulder arthroplasty. The glenoid guide includes a reverse tubular drill guide extending from the upper surface along a reverse alignment axis configured preoperatively with a patient-specific orientation and insertion location for guiding a glenoid baseplate into the glenoid face for reverse shoulder arthroplasty.

Patient-specific glenoid guides

An alignment plate can be designed and formed based upon a known geometry of a subject, such as a human patient. The alignment plate can include various members, such as a plurality of fingers or legs, to contact the selected points of the anatomy. Based upon contact of the fingers at the selected points of the anatomy, the alignment plate can be aligned at a preselected or predetermined alignment with a portion of the anatomy, such as an acetabulum.

An orthopedic device includes a patient-specific acetabular guide that may be used for preparing an acetabulum of a patient to receive an acetabular implant. The acetabular guide has a body with an outer three-dimensional surface configured to match an acetabulum of a specific patient's hip joint designed from data of the patient's hip joint. The acetabular guide may further include a peripheral annular rim.

A patient-specific osteotomy guide according to the present disclosure includes a three-dimensional bone-engaging inner surface configured to closely mate and conform to a corresponding portion of a specific patient's tibia. A resection slot at a patient-specific position and orientation to guide a cutting tool to perform an osteotomy according to a preoperative plan for the patient. An axial guide at a patient-specific position and orientation to guide a tool to perform an ACL/PCL reconstructive procedure according to a preoperative plan for the patient.

HTO guide with optional guided ACL/PCL tunnels

A system and method for aligning a guiding pin relative to a glenoid including a guiding pin insertion guide for orienting the guiding pin relative to the anatomic structure and an axis alignment device. The guiding pin insertion guide includes a base plate and a movable pin orientation device coupled to and extending from the base plate. The axis alignment device has a plurality of through holes that each define a different alignment axis. The guiding pin mates with one of the through holes to align the guiding pin at a patient-specific alignment axis, the guiding pin is then received within the guiding pin insertion guide when mated with the one of the through holes to align the guiding pin insertion guide along the patient-specific alignment axis relative to the base plate, and the guiding pin insertion guide is fixed to the base plate along the patient-specific alignment axis.

Adjustable glenoid pin insertion guide

A humeral cut guide system for resectioning or resurfacing a humeral head. The humeral cut guide system includes a primary cut guide member configured to be removably coupled to the humeral head. The primary cut guide member includes a patient-specific bone-engaging surface, a primary elongate slot that defines a primary cutting plane, and a pair of cylindrical apertures configured to receive a pair of guide pins. A secondary cut guide member includes a pair of through-holes configured to mate with the pair of guide pins, and the secondary cut guide member includes a secondary elongate slot that defines a secondary cutting plane.
