Atraumatic compartment syndrome of the dorsal compartment of the upper arm.

partment pressures that exceed capillary perfusion, causing ischemia and edema within the compartment. This has been well characterized in the lower leg following excessive muscle strain, tibia fracture, or other blunt trauma and in the forearm following blunt trauma. There are few reports of dorsal compartment syndrome of the upper arm. A literature review found only one previous case without known preceding trauma.
