Anatomy of the radial nerve motor branches in the forearm.

Knowledge of radial nerve motor branch anatomy is important when performing surgery in its vicinity, neurorrhaphy, and nerve blocks and for understanding the rate and order of recovery of muscle function after injury. Twenty normal fresh cadaver arms were dissected to quantitate radial nerve motor branch anatomy in the forearm. Though variable in individual specimens, innervation order from proximal to distal (based on mean shortest branch lengths) was brachioradialis, extensor carpi radialis longus, supinator, extensor carpi radialis brevis, extensor digitorum communis, extensor carpi ulnaris, extensor digiti quinti, abductor policis longus, extensor policis longus, extensor policis brevis, and extensor indicis proprius.

Squamous cell carcinoma complicating chronic osteomyelitis in a toe: a case report and review of the literature.

Squamous cell carcinoma arising from chronic osteomyelitis is uncommon. Although the majority of cases occur in the lower extremity, incidence in the foot is relatively rare, and in the toe, exceptional. This report illustrates a particularly unusual incidence of squamous cell carcinoma complicating chronic osteomyelitis of the hallux.
