Right distal anterior leg and dorsum of a cavus foot with an extensor primi internodii hallucis, arising from the extensor hallucis longus, which communicates with the extensor hallucis brevis. BaseMT2, base of the second metatarsal; EDL, extensor digitorum longus; EHB, extensor hallucis brevis; EHL, extensor hallucis longus; EPIH, extensor primi internodii hallucis; TibAnt, tibialis anterior. *Tendinous intersection between the extensor primi internodii hallucis and the extensor hallucis brevis.

Shank, tarsus and foot musculature of Xenopus laevis. Right shank and tarsal musculature in dorsal (A) and ventral (B) views. Dorsal view of specimen (C) showing location of cross‐sections through the shank (D,E) and tarsus (F). Right foot musculature in dorsal (G) and ventral (H) views. Attachment sites on the right tibiofibula in dorsal (I) and ventral (J) views, and for the right tarsus in dorsal (K) and ventral (L) views.

Endoscopic ganglionectomy of the extensor digitorum longus tendon of the right foot: an extraganglionic approach. The patient is in a supine position. The distal portal is the viewing portal, and the proximal portal is the working portal. The proximal part of the ganglion sac is resected by the shaver with caution to preserve the extensor tendons and the extensor digitorum brevis muscle. AS, arthroscopic shaver; EDL, extensor digitorum longus tendon; EDB, extensor digitorum brevis muscle; G, ganglion.

(A, B) Dorsal and ventral view of the free dorsal plantar artery combined with the extensor digitorum brevis tendon; (C). After loosening the tourniquet, the flap was ruddy in color and blood supply was good; (D) The appearance of the transferred dorsal foot flap combined with extensor digitorum brevis tendon on the dorsum of the hand.
