The deep fascia of the foot is thin on the dorsum of the foot where it is continuous with the inferior extensor retinaculum. Over the lateral and posterior aspects of the foot, the deep fascia is continuous with the plantar fascia (deep fascia of the sole).
The first is placed distal to the anterior inferior fibula, through the inferior extensor retinaculum and capsule.
The deep peroneal nerve can become compressed in the fibro-osseous tunnel underneath the inferior extensor retinaculum. Here the EHL crosses over the nerve and predisposes a patient to nerve compression.
The lateral root of the inferior extensor retinaculum originates superficial to the peroneal tendons and inserts on the lateral aspect of the anterior process of the calcaneus.
The intermediate layer has two components: the intermediate root of the inferior extensor retinaculum and the cervical ligament.
