The MRI demonstrated avulsion of the pectoralis major tendon from its insertion on the humerus with retraction as well as strain of the anterior deltoid (Figures 2 and 3).

Intracompartmental pressure readings in the anterior compartment of the arm taken about the midpoint of the biceps at the point of maximal swelling were 37, 39, and 42 mmHg with a diastolic blood pressure of 71 mmHg (Figure 4).

Immediately, a large amount of hematoma was expelled and the muscle bellies visibly bulged from the incision sites (Figures 5 and 6).
Hematoma evacuated from the anterior compartment of the arm.

Upon further dissection, both heads of the pectoralis major were found to be avulsed from the proximal humerus (Figure 7).
D: deltoid; P: repaired pectoralis major.
