A Rare Case of Quadratus Femoris Muscle Rupture After Yoga Exercises.

We present a case of a female patient with left groin pain after intense yoga exercises. The patient presented abnormal pattern of gait with no swelling over the groin, thigh, or buttock. Magnetic resonance imaging demonstrated a tear of the quadratus femoris muscle with an associated extensive hematoma formation. Patient was treated with a rehabilitation program consisting of nonsteroidal anti-inflammatory drugs and physiotherapy. At the follow-up control, the patient had improved her pain and flexibility of the hip, and gradually she returned to daily activities and yoga exercises. Such an entity is a rare cause of hip pain after exercise and should be kept in mind by the orthopedic surgeon, in cases of gluteal pain after intense physical activity. Moreover, such a condition should be included in the diagnostic algorithm of unknown origin hip pain.
