There are three main types of snapping hip: external, internal, and intra-articular. External snapping hip is caused by increased tension in the iliotibial band over the greater trochanter with repeated flexion and extension. Internal snapping hip involves snapping of the iliopsoas tendon over the femoral head. Intra-articular snapping hip is caused by labral tears or loose bodies in the hip joint. Conservative treatments include rest, stretching, strengthening, and therapies like cold compression, while operative options involve procedures like Z-plasty of the iliotibial band or arthroscopic surgery to address intra-articular issues.
