In 17 adult and 3 full term fetuses the hip joints were dissected to expose the insertion of gluteus minimus.
An attachment of the deep surface of the tendon as it passes over the hip joint capsule was found in every
case. Histological examination of this insertion confirmed the presence of short intramuscular tendons firmly
anchoring the tendon to the capsule. It is suggested that this attachment retracts the capsule during hip joint
motion, thereby preventing capsular entrapment.
