Some fibers insert into the finger's dorsal aponeurosis, why the muscle acts similar to a dorsal interosseus in the middle finger.
Interosseus recurrent labeled at lower left.
In the deep layer, the tibialis posterior has its origin on the interosseus membrane and the neighbouring bone areas and runs down behind the medial malleolus.
Dorsal interosseus labeled at center right.
In the lower leg, the anterior tibial enters the extensor compartment near the upper border of the interosseus membrane to descend between the tibialis anterior and the extensor hallucis longus.
The artery typically passes anterior to the popliteus muscle prior to passing between the tibia and fibula through an oval opening at the superior aspect of the interosseus membrane.
