INTRODUCTION​

• External hip snapping syndrome occurs when the Iliotibial band (IT band) snaps over the greater trochanter bump on the hip bone

• External hip snapping (also referred to as coxa saltans or dancer’s hip) can lead to snapping of the IT band which can be seen with certain hip motions

• External hip snapping is a sign that the IT band is too tight which leads to abnormal hip mechanics and oftentimes pain

• External hip snapping is often associated with greater trochanteric bursitis due to the repetitive inflammation and snapping

CAUSES

• External hip snapping is usually an overuse phenomenon. However, it can also occur after trauma. It is also more common in patients with tight IT band.

• It usually occurs with the hip in flexion, extension, and external or internal rotation

• It is very common in ballet dancers, runners, soccer players, and any athlete that does repetitive hip motions

SIGNS AND SYMPTOMS

• Patients with external hip snapping have pain in the outer part of the hip or thigh 

• They often report seeing the snapping of the IT band over the hip bone 

• Difficulty walking and physical activities may result

TREATMENT​​

• A course of rest, ice, anti-inflammatories, aggressive IT band stretching, and a home exercise program is the mainstay of treatment for external hip snapping. More than 90% of proximal hamstring injuries are treated with this program

• Cortisone injections may be an option in patients with significant greater trochanteric bursitis emanating from the snapping

• Surgery is considered in patients with failure of extensive conservative management

• Surgery consists of loosening the IT band, usually through Z lengthening of the IT band

        PREVENTION

• Strengthening and stretching the IT band, avoiding repetitive hip motions, and warming up prior to physical activity can help decrease the chance of external hip snapping
