External Snapping Hip Syndrome Causes, Symptoms & Treatment

Overview

Athletes with external snapping hip syndrome often notice a visible or audible snapping on the outer side of the hip during certain movements. This is especially noticeable when transitioning from hip flexion to extension, such as when standing up, walking, or climbing stairs.

The snapping occurs because soft tissue muscles or tendons rub against a bony prominence in the hip. In most cases, a tight iliotibial (IT) band moves back and forth over the greater trochanter, producing the characteristic popping sensation and sound. This mechanical friction is the hallmark of an external snapping hip.

What causes External Snapping Hip Syndrome?

External snapping hip occurs on the outer side of the hip and is typically caused by repetitive motion or tight soft tissues.

The condition most commonly develops when:

• The iliotibial (IT) band, a thick band of fibrous tissue running along the outer thigh, snaps over the greater trochanter of the femur. Because the IT band is naturally tight and heavily used during movement, this is the most frequent cause of external snapping hip syndrome.
• The gluteus maximus muscle shifts over the greater trochanter during hip motion, producing a snapping sensation.

1. How the Injury Occurs

• Repetitive hip flexion and extension
• Tightness in the IT band or surrounding muscles
• Muscle imbalance or poor hip mechanics

Over time, repeated friction leads to irritation and may progress to pain and inflammation.

2. Common Everyday Causes

• Walking long distances
• Repeated stair climbing
• Sitting for prolonged periods followed by standing
• Sudden increases in physical activity

Sports Associated With Snapping Hip Syndrome

Athletes who frequently perform repetitive hip movements are at higher risk, including those involved in:

• Dance (especially ballet) – extreme hip motion and flexibility demands
• Gymnastics – repetitive hip rotation and extension
• Short-distance running – repeated hip flexion and extension
• Soccer – cutting and lateral movements
• Rowing – repetitive hip motion under load
• Martial arts – kicking and rotational hip movements

Symptoms

People with external snapping hip syndrome typically experience a snapping or popping sensation on the outside of the hip during movement. Although many individuals initially report no pain, symptoms can progress over time.

Common snapping hip syndrome symptoms include:

• A visible or audible snapping sensation during walking or exercise
• Muscle weakness around the hip
• Difficulty walking or participating in sports
• Trouble sleeping on the affected side
• Occasional feelings of the hip “giving way” or buckling
• A noticeable limp during activity
• Discomfort during hip abduction (moving the leg away from the body)

With ongoing irritation, inflammation of the tendons (tendinitis) or surrounding bursae may develop, leading to pain.

Non-operative treatment

Snapping hip syndrome treatment is usually non-surgical and focuses on reducing inflammation and correcting muscle imbalances.

Common treatment options include:

• Rest and activity modification
• Ice to reduce inflammation
• Over-the-counter NSAIDs for pain relief
• Corticosteroid injections into the hip bursae to decrease inflammation
• Physical therapy, including stretching and soft tissue techniques targeting the IT band and surrounding muscles

Most patients experience significant improvement with conservative care.

Surgical Treatment

Surgery is rarely needed for external snapping hip syndrome. In severe cases where symptoms persist despite extended non-operative treatment, surgical release or lengthening of the iliotibial band may be considered. This procedure reduces friction over the greater trochanter and relieves persistent pain associated with hip abduction.
