Common hip injuries in sport

As a major weight-bearing joint, normal hip function is fundamental to successful sporting participation. Not only is it important in running-, jumping- and kicking-based activities, it also contributes to the generation and transference of forces in upper limb-dominated activities. Injuries to the hip do not account for a large proportion of the sports physician's workload, but may result in significant morbidity. The wide variety of acute, subacute and chronic injuries, affecting both the joint and surrounding soft tissues, can prove a diagnostic dilemma. The predisposition and the types of injuries around the hip vary with the age of the athlete. The young child rarely sustains a significant injury but one should be aware of orthopaedic conditions common in this age group that may manifest themselves through exercise. The immature skeleton of the adolescent is relatively injury prone and the demands of sport often exceed the capacity of the growing musculoskeletal system. In adults and older athletes, a further spectrum of injury exists, along with the effects of aging tissues and the concerns of degenerative joint disease. Rational treatment is based on a clear diagnosis developed through sound knowledge and a thorough history and examination. For the sports physician, treatments are typically early physical therapy and structured, progressive rehabilitation programmes which are individualised to the needs of the athlete. The spectrum of hip injuries is reviewed with current recommended diagnoses and management.
