Abstract:
The use of intraoperative fluoroscopy is standard among hip arthroscopist to evaluate and confirm the adequacy of cam resection in patients with femoroacetabular impingement syndrome. However, given the inherent limitations of fluoroscopy, additional intraoperative imaging, such as ultrasound, should be pursued. We offer a technique to measure alpha angles intraoperatively using ultrasound to determine adequate cam resection.
