Overview
The shoulder (glenohumeral) joint is the most often dislocated diarthroidal joint in the body, and therefore has many surgeries performed to it. One of the more common injuries to the shoulder is a rotator-cuff tear. There are two methods to repair such an injury, open shoulder, or arthroscopic surgery. Opening the shoulder is much more invasive and is generally not preferred. Arthroscopic surgery is less invasive, however, the surgeon is required to look at a 2D image of what he/she is working through a limited field of view of the injury.
Currently there are no tools available to measure the extent of rotator cuff tears arthroscopically. We have prototyped an arthroscopic tool consisting of a nicron measurement wire affixed to a hand driven gearing system to measure the dimensions of rotator cuff tears in-vivo during surgery. Knowledge of the tear dimensions will facilitate the proper technique of repair.
