BACKGROUND: Hand injuries occur often in daily life both in athletes and non- athletes. One of the common injuries that many patients experience are ligamentous injuries to the interphalangeal and metacarpophalangeal joints. These joint injuries cause significant joint pain and instability. This may interfere with functions such as catching a ball and twisting and turning activities of the hand including throwing. Long-term sequelae include joint stiffness, pain and residual loss of function. This may include weakening of the hand and result in permanent effect on the performance. If left untreated or poorly managed, these may develop joint contractures. Depending on the grade of tear of the collateral ligaments treatment options may include splinting with occupational therapy or surgical repair /reinsertion of the collateral ligament tear with occupational therapy. The study's main objective is to review the effectiveness of ligament repairs in stabilizing the joint and allowing improved range of motion and function following use of Mitek anchors. METHODS: I plan to conduct a retrospective study to evaluate functional outcomes of patients who underwent collateral ligament repairs using Mitek anchors from February 2017 to April 2021 versus non-operative patients. Two authors will review data obtained from medical records to obtain information regarding the patient’s age, gender, affected finger, sport injury, grade level of sprain, surgical procedure, postoperative management including occupational therapy data such as range of motion and strength. Radiographic data will also be reviewed. ANTICIPATED RESULTS: Patients who undergo repair of ligament with Mitek anchors are hypothesized to have improved range of motion in a shorter span of time as compared to non-operative patients treated with splinting and occupational therapy alone. The study will allow for comparison of functional outcomes in the two groups of patients.
