The primary CCI of the distal tibial nerve (Fig. 139.19) with its plantar nerve and medial calcaneal nerve branches is situated at its NF interface (Fig. 139.20) with the flexor retinaculum (distal edge primarily). In the figures, CCIs are identified with blue dots; the cutaneous nerve trunks are shown in red. Bystander disease is most commonly manifested in the plantar fascia. The author has found that a combination of NF treatments and calciol(cholecalciferol) transdermal cream is effective in treatment of foot conditions such as plantar fasciitis (structures underlying medial calcaneal nerve and medial and lateral plantar nerves)and sesamoiditis (branches of medial plantar nerve). The CCI for the cutaneous deep peroneal nerve is shown in Fig. 139.21 and is a common cause of great toe pain.
