Abstract:
There are many causes of acute hip pain. Obturator internus (OI) muscle strain is a rare cause of the presentation. We report a case of OI muscle strain in a 15-year-old ski racer who presented with new onset acute right hip pain. Magnetic resonance imaging showed enhancement of the obturator internus muscle indicating muscle injury. Patient was treated conservatively with target physical therapy and NSAIDs for pain management. This case illustrates an atypical diagnosis for a common chief complaint.

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
