A 33-year-old female visited to our hospital complaining of severe painful swelling in her right buttock. Ten hours previously, she had fallen down stairs. Motor power of her ankle and foot were zero to trace and the intracompartment pressure of the gluteal region was 50 mmHg. MRI showed diffuse intramuscular edema of right gluteal muscle. Emergency fasciotomy of the gluteal compartment was per-formed and her neurologic signs gradually improved at a postoperative 24 hours. She recovered completely at postoperative 14 days without further sequelae.
