Coxa saltans, or “snapping hip,” refers to various conditions that produce a palpable or audible snapping of the hip after movement. We present an uncommon case of coxa saltans in a patient with a snapping proximal hamstring tendon. Findings of dynamic ultrasound evaluation were used to confirm the source of snapping, characterized by a lateral subluxation of the conjoint tendon over the ischial tuberosity. Our patient was treated nonoperatively, and we observed mild improvement of her symptoms. Few cases of similar pathological findings have been described, with varying causes of tendon instability. The results of the current case may help physicians in diagnosing and treating this condition.
