%X To demonstrate and evaluate muscle injuries, magnetic resonance imaging (MRI) is considered the most sensitive and specific method of choice. We report an isolated brachialis muscle rupture caused by resisted flexion and pronation of the lower arm. Physical examination combined with ultrasound evaluation confirmed the diagnosis of ruptured brachialis muscle. Treatment was non-operative with full restoration of function.Trauma to the elbow caused by lifting heavy objects frequently involves rupture of the tendon of the biceps brachii muscle. Less frequently a rupture of the brachialis muscle occurs. After an extensive online search, we found only five cases involving traumatic rupture of the brachialis muscle had been described in the past 20 years. To demonstrate and evaluate muscle injuries, magnetic resonance imaging (MRI) is considered the most sensitive and specific method of choice. We report an isolated brachialis muscle rupture caused by resisted flexion and pronation of the lower arm. Physical examination combined with ultrasound evaluation confirmed the diagnosis of ruptured brachialis muscle. Treatment was non-operative.A 45-year-old male, right-handed, amateur bodybuilder and metalworker presented to our emergency department with pain in the left elbow after lifting his motorcycle. At the time of injury, he noticed a sudden snap in his left elbow and felt immediate pain and weakness. There were no previous injuries to the elbow, but the patient reported a visible dell on the medial surface of the proximal brachial portion of the arm. There were no paresthesias of the left upper extremity. The patient denied the use of medication, drugs or food supplements, and denied smoking or excessive alcohol use as well.On physical examination, maximum pain was elicited on active flexion and pronation of the lower arm. Passive extension and resisted flexion of the elbow enhanced the pain on the medial side of the elbow. Movement of the palm and fingers did not increas
