He reported no specific history of recent trauma, fever, chills, or prior infection elsewhere; however, he had increased swelling and purulent drainage from the posterior aspect of his arm near his axilla (Figure 1).
Computed tomography images of the patient's humerus: (A) 3-dimensional reconstructed image shows a lytic defect (arrow); (B) axial image shows bony sequestrum (arrow).

Computed tomography scans revealed a lytic defect and bony sequestrum of the humerus suggestive of osteomyelitis (Figure 2).
A proton density-weighted, fat-suppressed image of the tenodesis site shows a fluid collection with increased signal and a protruding screw (arrow).
