Unterarmfaszie

Unterarmfaszie refers to the fascial layers that enclose and compartmentalize the muscles of the forearm. These fascial sheaths are composed of dense connective tissue and play a crucial role in supporting the muscles, facilitating their coordinated movement, and maintaining the integrity of the forearm's structure. The deep fascia of the forearm is a continuous layer that envelops the entire musculature. It gives rise to intermuscular septa that extend inwards to the bones, dividing the forearm into distinct compartments. These compartments typically include an anterior (flexor) compartment and a posterior (extensor) compartment. Each compartment contains a group of muscles that share a similar function and nerve supply. The fascial envelopes within these compartments are essential for generating and transmitting force efficiently. They prevent the muscles from bulging excessively during contraction and allow for smooth gliding between adjacent muscle groups. The faszie also provide attachment points for some muscles and protect the underlying nerves and blood vessels. Injury to the forearm fascia, such as in compartment syndrome, can lead to significant pain and functional impairment due to increased pressure within these confined spaces.
