Medial epicondylitis caused by injury to the medial antebrachial cutaneous nerve: a case report.
A 35-year-old man who had chronic elbow pain due to medial epicondylitis received a steroid injection into the medial epicondyle. This was followed immediately by increased pain and symptoms of dysesthesia in the distribution of the medial antebrachial cutaneous nerve. On surgical exploration 9 months later, the nerve was found to lie directly over the medial epicondyle and appeared to have sustained an injection injury. This report draws attention to the fact that because the posterior division of the medial antebrachial cutaneous nerve may lie directly over the medial epicondyle, it may be at risk of direct injury if injections are given into the epicondyle.
