Iliopsoas Muscles Injuries

Abstract

The anatomy of the iliopsoas is complex, extending from the lumbar fossa to the upper thigh. Traumatic lesions of this muscle are rare and often misunderstood. Team sports and canoeing are the activities that most commonly produce traumas of the psoas. The lesions are to be found in three highly distinct locations. Lesions of the fleshy body lead to a noisy clinical picture with large hematoma. Injuries to the myotendinous junction are often small in size, resulting in very late diagnosis. Low disinsertions usually occur in older athletes. They are immediately disabling. Ultrasound or MRI scans will confirm the diagnosis at an early stage. Medical and functional treatment is the rule, except when there is a compressive hematoma or displaced avulsion of the lesser trochanter, in which case surgery may be considered.
