RARE CASE OF HIP PAIN DUE TO ILIOPSOAS TENDON RUPTURE; A CASE REPORT AND REVIEW OF THE LITERATURE.

Objective: Hip pain is common in patients of advanced age and has a very broad differential. Of the potential aetiologies, iliopsoas tendon ruptures are rare. Consequently, there is a paucity of literature on iliopsoas rupture in the older adult population, and its rarity can lead to a delay in its diagnosis. When iliopsoas ruptures do occur, they are typically secondary to trauma; however, they can occur spontaneously. Iliopsoas injuries can be disabling, but they respond well to conservative management. We report here a case of a 70-year-old woman who presented to an unaffiliated emergency department with left anterior hip pain 2 weeks after a fall from standing height.

Results: Initial X-ray and computed tomography were negative for fracture, and the patient was discharged with home health physical therapy. Her symptoms persisted. At a subsequent emergency department visit several weeks later, magnetic resonance imaging revealed a complete left iliopsoas tendon rupture with retraction. She was treated conservatively and made a complete recovery after physical therapy.

Discussion: This paper reviews the literature related to iliopsoas injuries, highlights the importance of iliopsoas tendon injuries among the differential for acute hip pain, and provides management recommendations for this rare, but probably underdiagnosed, injury. This treatable condition warrants further attention, as delay in diagnosis can prolong morbidity.
