Superior Gluteal Nerve Injury
- Causes: Intramuscular injection in the gluteal region, greater trochanter fracture, posterior hip joint dislocation

- Deformity: Limb (Waddling Gait) (Gluteal Gait) (Lurching Gait)
- Muscles paralyzed: Gluteus medius, Gluteus minimus, Tensor fasciae latae
- Motor loss: Abduction of thigh, medial rotation of thigh
- Trendelenburg’s sign: A patient with a weak or paralyzed gluteus medius and minimus will experience a pelvic drop over the swing limb when standing on the affected limb. The patient compensates for the pelvic drop by lurching the trunk to the affected side.
