This article discusses three selected areas of sports medicine in which MRI is useful. The first is muscle injuries and includes the MRI findings in muscle tears, contusions, and myositis ossificans. The second section discusses the usefulness of MRI in imaging the athlete with groin pain, which is a difficult clinical problem for the orthopedist. The ability of MRI to differentiate between such causes of groin pain as osteitis pubis, bursitis, and stress fractures is shown. The final section covers plain radiographic and MRI findings in osteochondritis dissecans. Also discussed is the MRI staging of osteochondritis dissecans, which is important in treatment decisions and surgical planning.

Chronic groin pain is common in soccer players because of the biomechanics of kicking causing recurrent stress to the abdominal muscles, groin flexors, and adductor muscles. Myositis ossificans in adductor muscles is a rare cause of chronic groin pain in soccer players. Only two cases have been reported and the iliopsoas muscle was involved in both. This case report emphasises the importance of direct radiography for diagnosis in chronic groin pain and is a reminder that the development of myositis ossificans in the adductor muscles may be a cause.

Iliopsoas haematoma is a well-recognized complication of haemophilia, and is considered as potentially life threatening and significantly associated with morbidity. There are only rare reports on the incidence or outcomes of iliopsoas bleeding since the widespread usage of modern therapies for haemophilia. In this study, we present the experience of Ege University Haemophilia Centre with iliopsoas bleeding and its early and late complications. We reviewed 146 haemophiliacs (106 haemophilia A, 40 haemophilia B). Fourteen iliopsoas bleeding episodes were identified in eight haemophiliacs. Three patients (37%) had one episode, four (50%) had two episodes and one (13%) had three episodes. Two patients had a high titre inhibitor against factor VIII and accounted for three bleeding episodes (21%). We did not observe any episodes in six patients receiving prophylaxis. Iliopsoas haematomas were confirmed by ultrasonography in all patients. In physical examination, the most common symptoms were thigh, hip and groin pain, hip flexion contracture, abdominal tenderness and paraesthesia in the distribution of the femoral nerve. The mean duration of therapy with clotting factor concentrate was 7.8 +/- 1.6 days. The mean duration of hospitalization was 4.8 +/- 2.0 days. All patients started to receive a physical therapy program 6.0 +/- 2.4 days after the initiation of haemostatic therapy which lasted 20.0 +/- 6.0 days. Ultrasonographic findings related to iliopsoas haematoma disappeared in all patients within 3 months from the initial episodes. Only in one patient with mild haemophilia A, heterotopic bone formation (myositis ossificans) developed as a long-term complication. In conclusion, pain around the hip joint, femoral neuropathy and hip flexion contracture in a patient with haemophilia should alert the physician to the possibility of an iliopsoas haematoma. Early and effective factor replacement therapy is essential in the prevention of the complications.

A 20-year-old male collegiate soccer goalkeeper presented to an athletic trainer during the season complaining of right (dominant kicking leg) groin pain. The athletic trainer identified a mass and hematoma and suspected myositis ossificans. The patient was referred to the team physician, who ordered radiographs and magnetic resonance imaging to confirm the diagnosis and rule out other injuries. Imaging demonstrated an adductor longus muscle strain with myositis ossificans. J Orthop Sports Phys Ther 2020;50(10):586. doi:10.2519/jospt.2020.9573.
