Description
Summary:Includes bibliographical references (p.71-78). === Orthopedic oncology provides for a challenging field in prosthetic design, especially in proximal humeral sarcoma cases. In these cases a large volume of bone an muscle is removed as a result of the sarcoma. This leaves insufficient musculature to stabilize an un-constrained prosthesis. This report deals with the design and testing of constrained total shoulder replacements, as their inherent built-in stability compensates for lost musculature stability. The weakest area of any shoulder replacement is the fixation of the glenoid component to the scapula. The design of an innovative glenoidal attachment system was the main focus of the project.
