The ulnar collateral ligament (UCL) is a three-part ligament connecting the ulna and humerus bone (Erickson et. al., 2015). It is located on the medial side of the elbow. This ligament tears due to high forces through the elbow, which usually occurs in athletes who participate in throwing sports – including baseball, javelin, and tennis (Zaremski et. al., 2017). The only way to reattach the ligament is to have reconstructive surgery using an autograft from another tendon in the foot, hamstring, knee or forearm. Recovery from surgery can take up to two years and in many cases, frequent physical therapy visits. The device is aimed to be used in conjunction with physical therapy and the physical therapist will be able to track progress outside the office. The target population includes those with elbow injuries specifically those who have had UCL surgery; however, it will be marketed to the physical therapists, as they will be the ones prescribing the exercises.
