Answer- C. Chronic osteomyelitis
Osteomyelitis is an infection of bone and bone marrow. It may be subdivided into acute, subacute, and chronic stages.
Chronic osteomyelitis:
* Chronic osteomyelitis results from incompletely healed or persistent suppurative acute infection.
* Chronic osteomyelitis is characterized by alternating periods of quiescence and recurrence of pain, swelling, and sinus tract drainage.
X-Ray findings:
* Chronic osteomyelitis characterized by marked cortical thickening or periosteal reaction producing a very dense appearance on radiographs.
* Bone resorption with thickening & sclerosis, pieces of dead bone (sequestra) & form of a distinct bony sheath (involucrum)
* Sequestration is a hallmark of chronic active osteomyelitis, and adequate treatment requires surgical removal of this necrotic bone nidus
