Abstract:

Objective To investigate the innervation of the radial nerve in the posterior region of the forearm muscles and provide the anatomical basis for autologous skeletal muscle graft. Methods Ten forearms were dissected from five fresh adult cadavers to observe the extramuscular distribution of the nerve and the intramuscular distribution of the nerve using the standard Sihler's nerve staining method. Results The intramuscular nerve branches were stained purple-black and could be visualized clearly. The muscles were classified into different categories  according to common shapes and intramuscular neural distribution. Conclusions According to the intramuscular neural distribution, some of the forearm muscles can be split into different compartments and serve as independent function units for segmental muscle transplantation. the outcomes of our anatomical investigation is of crucial guiding significance for clinical muscle transplants.

Key words: Posterior region of forearm, Sihler's staining, Intramuscular nerve distribution, Neuromuscular compartment
