![]() The superficial volar compartment is innervated by median and ulnar nerve and includes:ĭeep volar compartment (Innervated by Anterior Interosseous Nerve (AIN)) The volar compartment consists of the superficial volar and deep volar compartment. Houses the finger extensors and is innervated by the posterior interosseous nerve. The dorsal and volar compartments are separated by the interosseous membrane.ĭorsal Compartment There are four compartments of the forearm: dorsal, superficial volar, deep volar, and the mobile wad. Hematoma in patients treated with anticoagulants.Fractures of the forearm - including both diaphyseal forearm fractures and fractures of the distal radius (most common).Acute, irreversible muscle changes (i.e., necrosis) in 3 to 8 hoursĮtiology Traumatic.Acute, irreversible nerve damage in 12 to 24 hours.Acute, sensory changes develop after 30 minutes of ischemia.Although uncommon, compartment syndrome of the forearm is a well recognized diagnosis that can lead to significant morbidity and mortality if not diagnosed and treated early in the clinical course. ![]() ![]() It may or may not be preceded by fracture or traumatic injury. In other words, it can be described as a bleeding or edema that leads to increased pressure within the fascial compartment and compromises circulation within that space, as well as the function of tissues in that area, causing ischemia. Definition/Description Ĭompartment Syndrome of the forearm is a condition in which pressure inside the closed osteofascial compartment increases to such an extent that there is a compromise of microcirculation, leading to tissue damage. ![]()
