[Snapping hip of internal origin]

The paper presents an unusual case of internal snapping hip in an 18 year old female, due to abnormal iliopsoas tendon tension. Operative treatment with precision of the fibrous slip over the rim of the pelvis gave a very good result, with slight limitation of active hip flexion. Various opinions on the pathogenesis and treatment of this rare condition have been presented. Lack of snapping in a supine position during clinical assessment has been emphasized.
