Numerical analysis of a 3-screws baseplate for reverse shoulder arthroplasty

2011
Student Projects

Abstract

Reverse shoulder arthroplasty has become the classical treatment for glenohumeral joint arthritis associated with rotator cuff dysfunction. The design of the prosthesis, the fixation of the implant and the surgical technique are however still to be improved. One of the remaining question is the number and positioning of the screws that stabilize the baseplate in the glenoid bone. The goal of this project is to evaluate the advantage and stability of a 3-screws baseplate, compared to a more conventional 4-screws baseplate. This project is mainly based on finite element analysis.

Rotator cuff tear

Rotator cuff tendinopathy is a process of senescence. The pathophysiology is mucoid degeneration. Most people develop rotator cuff tendinopathy within their lifetime. As part of rotator cuff tendinopathy, the tendon can thin and develop a defect. This defect is often referred to as a rotator cuff tear. Acute, traumatic rupture of the rotator cuff tendons can also occur, but is less common. Traumatic rupture of the rotator cuff usually involves the tendons of more than one muscle.

Shoulder

The human shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder joints. The shoulder joint, also known as the glenohumeral joint, is the major joint of the shoulder, but can more broadly include the acromioclavicular joint. In human anatomy, the shoulder joint comprises the part of the body where the humerus attaches to the scapula, and the head sits in the glenoid cavity.

Project

A project is any undertaking, carried out individually or collaboratively and possibly involving research or design, that is carefully planned to achieve a particular goal. An alternative view sees a project managerially as a sequence of events: a "set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations". A project may be a temporary (rather than a permanent) social system (work system), possibly staffed by teams (within or across organizations) to accomplish particular tasks under time constraints.
