Proper function of the hip joint is imperative for athletes who participate in sporting activities that rely on utilization of the lower extremity; these primarily include kicking, running, and jumping activities. Sports-related injuries of the hip and groin are not frequent sources of disability in athletes; however, they may present a significant diagnostic dilemma, both from a clinical and radiological standpoint. Delay in diagnosis and treatment may result in undesired complications, such as premature degenerative disease, as well as time lost from athletic activities. Magnetic resonance (MR) imaging of the hip, particularly following the intra-articular administration of gadolinium, has proven to be extremely valuable in the diagnosis of radiographically occult osseous abnormalities as well as soft-tissue injuries, such as pubalgia, musculotendinous abnormalities, and bursitis. This article will review several pathological conditions of the hip and groin in both recreational and professional athletes, with an emphasis on MR imaging as the modality of choice in the diagnosis of these injuries.
