Diagnostic Code 8517 · 38 CFR §4.124a
The musculocutaneous nerve controls your biceps and brachialis muscles, which are the main muscles for bending your elbow. It also provides sensation to the outer side of your forearm. When this nerve is damaged, you have significant difficulty bending your elbow against resistance and may experience numbness along the outer forearm. Veterans may develop this condition from shoulder dislocations, upper arm fractures, stab or shrapnel wounds, or surgical complications during military service.
