The posterior compartment of the arm is one of the two compartments in the arm.
A sheath of deep fascia surrounds the arm, the brachial fascia. Two intermuscular septa (medial and lateral) extend from it to attach to the humerus at the medial condylar ridge and lateral supracondylar ridge, respectively. These septa divide the arm into its anterior and posterior compartments.
