Lymphatic Plexus of the Palm, Posterior View

Description

Oriented to the posterior aspect of the hand and distal forearm, the composition centers on a superficial lymphatic plexus spread across the dorsum and tracking along the metacarpals toward proximal collecting vessels at the wrist. Extensor tendons course distally over the carpal region into the digits, held in place by the extensor retinaculum, while the underlying carpal bones, metacarpals, and proximal phalanges provide clear osseous landmarks. Superficial veins run in parallel and crossing patterns that mirror the lymphatic pathways, and peripheral nerves follow longitudinal trajectories between tendon groups. Relationships are easiest to appreciate where the lymphatics lie superficial to the extensor apparatus and dorsal venous network, then converge proximally. Dorsal hand lymphatics matter because they form the primary drainage route for much of the skin of the hand and digits, accompanying superficial veins before passing toward epitrochlear and axillary nodes. This is the anatomy behind postoperative swelling and lymphangitis tracking from a dorsal web-space infection, and it is also why dorsal venous cannulation, tendon lacerations, or dorsal incisions can disrupt superficial lymphatic channels and prolong edema. Small structures. Big consequences. For teaching, this posterior view works well in gross anatomy and clinical anatomy modules on upper-limb lymphatic drainage, and it pairs cleanly with surface anatomy of the dorsal venous network and extensor compartments of the wrist. In publishing and clinical education, it supports hand surgery, dermatology, and infection-control content where you need to explain how dorsal skin lesions, cellulitis, or surgical scars map onto collecting vessels and nodal basins.
