Quantifying the variability of glenoid geometry in intact and osteoarthritic shoulders

De Vries, C., 2014. PhD Dissertation . (BibTeX Citation)

The purpose of this project is to identify sources of variability within the glenoid of the scapula to assist in implant placement and design for Total Shoulder Arthroplasty (TSA). The glenoid is the socket component of the ball and socket connection of the shoulder joint. When a person has osteoarthritis, the glenoid can wear down, resulting in a loss of mobility, pain, or even causing the shoulder to dislocate. To restore range of motion, and reduce or eliminate pain, surgeons perform TSA. This surgery involves inserting a metal implant in the humerus, and a plastic implant in the glenoid. If the glenoid implant is improperly placed, it can wear out or potentially become dislocated within a ten year period. In some cases,the full range of motion is not returned to the patient. Due to the limited visual input during surgery, it can be difficult to obtain the correct angle of implantation. By studying the variability of healthy glenoids, it may be possible to estimate the original healthy geometry of osteoarthritic shoulders.
