Iliopsoas tenosynovitis is inflammation or damage to the iliopsoas tendon which is in the anterior hip. It usually occurs due to overuse of the hip flexors.
Symptoms include pain and possible snapping in the front of the hip. There is usually tenderness in the anterior hip, groin, or thigh. There is pain with flexion of the hip against resistance. Passive hip extension may be painful.
Treatment of iliopsoas tenosynovitis is with relative rest or avoiding all painful activities. Application of ice and anti-inflammatory medication may also help. Physical therapy with rehabilitative stretching and strengthening exercises is also effective in treating this condition.
