If left untreated, this can lead to ischemic contracture, which is a late sequelae of compartment syndrome that occurs when there is sustained ischemic damage to the muscles. Timely diagnosis and treatment are critical in reducing the extent of permanent changes within muscle and nerve tissue. No previously published studies have reported on the treatment of early ischemic contracture resulting from traumatic haematoma in the upper arm. We present an exceptional case involving a 17-year-old male who developed this condition following a collision during a basketball game, resulting in a haematoma with severe pain, tightness and restricted range of motion in the affected arm. He was treated through surgical intervention involving surgical muscle release, haematoma evacuation and continuous passive motion (CPM) postoperatively to restore the range of motion and improve overall function with complete recovery at the 27-month follow-up.
