The branches arising from the posterior trunk include iliolumbar artery, lateral sacral arteries and superior gluteal artery.
Its numerous branches supply the muscle and anastomose with the inferior gluteal artery branches while others perforate the tendinous medial attachment of the muscle to supply the skin over the sacrum where they anastomose with the posterior branches of the lateral sacral arteries.
