These muscles are responsible for extending the toes at the metatarsophalangeal joints and interphalangeal joints. Sensory Functions. The deep fibular nerve terminates in the dorsum of the foot as a cutaneous nerve. This innervates the webbed space of skin between the great toe (hallux) and the second toe.
What causes the deep fibular nerve to become entrapped?
This causes paralysis of the muscles in the anterior compartment of the leg, and so a patient loses the ability to dorsiflex the foot.
Why is the deep fibular nerve compressed?
There are two main reasons why the deep fibular nerve could be compressed. The first is that the anterior leg muscles have been excessively used and so are compressing the nerve within the anterior compartment. The patient will experience pain in the anterior leg.

What causes a deep fibular nerve to swell?
This syndrome is caused by bleeding or swelling within an enclosed bundle of muscles – known as a muscle compartment. The muscle compartment does not have the ability to increase its size and volume capacity due to surrounding tough fascia. Thus, any major swelling leads to the compression of the neurovascular structures that run through the compartment.
