A 19-year-old male construction worker presented with an injury to his left upper arm after lifting a heavy pipe. He reported an acute onset of sharp pain followed by swelling, warmth, and weakness with elbow flexion. The diagnosis of a distal biceps tendon rupture was made and elective repair was scheduled. Seventy-two hours later, the patient presented with a spontaneous draining wound on his anterior distal humerus. The wound was draining thick purulent material. The patient underwent surgery for irrigation and debridement of his abscess. Nearly 500 cc of hematoma and purulent fluid were evacuated. A large tear of both the biceps and brachialis muscle bellies were found. Cultures were obtained that revealed the infecting organism to be Streptococcus intermedius. Human immunodeficiency virus and hepatitis-C virus testing were negative, and no history, signs, or symptoms of any cause of underlying immunodeficiency were detected. No signs or history of drug use were present. He was discharged home on culture-specific oral antibiotics. At 4-month postoperative follow-up, the patient reported no pain or limitations. He has returned to full duty at his job. Elbow range of motion was measured from 7° to 150° of flexion. Strength of elbow flexion and extension was symmetric to the uninjured side. Pronation and supination of the forearm was symmetric on both sides. He has been released from scheduled follow-up and will be seen again on an as-needed basis.
