A stem portion is formed such that when implanted in a scapula the stem portion includes three cross-sections parallel to a medial lateral plane. The middle cross-section has a length in the medial-lateral direction which is shorter than the lengths of the other two cross-sections in the medial lateral direction.

Method of forming glenoid stem component for shoulder arthroplasty

A glenoid component includes a laterally facing bearing surface configured to engage a bearing surface of an element associated with a humerus, and a stem portion extending medially away from the bearing surface. The stem portion is configured such that when implanted in a scapula the stem portion includes three cross-sections parallel to a medial lateral plane. The middle cross-section has a length in the medial-lateral direction which is shorter than the lengths of the other two cross-sections in the medial lateral direction.

Glenoid component for shoulder arthroplasty

A method of making a glenoid component for shoulder arthroplasty includes obtaining a model of a glenoid vault morphology normalized from a population of a plurality of scapulae, the model being defined by a plurality of mutually parallel, triangular cross-sections, and producing a stem portion of the glenoid component based on the model.

A glenoid component apparatus for shoulder arthroplasty includes a bearing portion and a stem portion connected to the bearing portion. The stem portion is modeled from a normalized glenoid vault morphology. A method for making a glenoid component for shoulder arthroplasty includes obtaining a model of a normalized glenoid vault morphology and producing a stem portion of the glenoid component based on the model.
