Left femoral enlargement, sclerosis, and irregularity. Displaced and mildly comminuted fracture of the proximal 1/3 of the diaphysis along the upper margin of the cortical irregularity.
Small tubular fragment within the distal femoral diaphysis deep to a defect in the posterior cortex, and connecting to a sinus tract extending into the lateral thigh.
Anterior compartment abscesses and swelling.
Case Discussion
Chronic osteomyelitis of the thigh with many characteristic findings:
- cortical thickening/irregularity
- sequestrum
- sinus tract
- soft tissue abscess
At first glance, this may look like and osteosarcoma. However, the presence of a sequestrum, sinus tract, and abscess provide reassurance that this is chronic osteomyelitis.
