Definition[Bearbeiten]
The term intermuscular septum cruris refers to coarse layers of connective tissue fibres (aponeuroses) in the area of the lower leg that separate different muscles or muscle groups from each other.
Classification[Bearbeiten]
There are two muscle septa on the lower leg, each of which stretches between the fascia cruris (fascia of the lower leg) and the fibula (fibula).
Septum intermusculare cruris anterius[Bearbeiten]
It lies as a coarse fibrous layer between the extensor ligament and the fibular ligament and serves as a surface of origin for the muscles of both compartments. It is pierced in the proximal part by the fibular nerve.
Septum intermusculare cruris posterius[Bearbeiten]
The septum intermusculare cruris posterius lies between the fibularis loge and the flexor loge of the lower leg and is connected to the deep leaf of the lower leg fascia.
