dorsal expansions of lesser toes

dorsal expansions of lesser toes

fibrous tissue formed by extensor digitorum longus tendons extending to either side of lesser metatarsophalangeal joints to insert into deep transverse ligament; thicker, central parts (of the expansions) continue distally to dorsal surfaces of proximal phalanges, serving as points of insertion for extensor digitorum brevis tendons to toes 2, 3, 4; lumbrical and interosseous muscle tendons insert into medial aspects of expansions
