The term “snapping bottom” was initially used by Rask1 to describe subluxation of the long head of the biceps femoris tendon at the ischial tuberosity, in what we believe to be the only reported case of this phenomenon in the literature. This entity was discovered by reproduction of the snapping during active hip flexion and with direct palpation of the snapping long head of the biceps femoris tendon over the ischial tuberosity. After unsuccessful nonoperative treatment, a tenotomy was performed; all symptoms were alleviated. There are several etiologies of the snapping hip, “coxa saltans,” which include snapping of the iliotibial band or gluteus maximus over the greater trochanter, snapping of the the iliopsoas over the iliopectineal eminence, and intra-articular lesions2. However, subluxation of the proximal hamstring origin is rarely considered in the differential diagnosis. We present the case of a woman with coxa saltans caused by subluxation of the proximal hamstring origin over the ischial tuberosity. Institutional review board approval and the patient's informed consent for publication of this information were obtained.
