Athletes with CECS report pain, pressure, and occasionally neurologic symptoms in the affected compartment during exercise that abates with rest. Although many treatment options have been proposed, athletes often require a fasciotomy to return to unrestricted sports participation. Surgical success rates vary; complications are not uncommon; and after surgery, it usually takes athletes 6 or more weeks to return to unrestricted impact activities. This case report describes a new ultrasound-guided fasciotomy technique for the treatment of anterior leg compartment CECS. The procedure required a 3 mm incision, was performed in the office under local anesthesia, and allowed the athlete to resume running within 1 week of the procedure. Although the preliminary results of this study are promising, further translational research is required before the widespread adoption of this procedure is recommended.
