6. A circumscribed, oval cavity surrounded by a zone of sclerosis at the proximal tibia (Brodie’s abscess) This is a lateral view X-ray of left tibia and fibula. There is a marked periosteal reaction at the diaphysis (Type IIb subacute OM)

11. Chronic Osteomyelitis Prepared by: Tg.Putri Madina bt Tg.Ariff @ Zainuddin

18. Anatomical Type Cierney and Mader staging system of Chronic Osteomyelitis Stage Characteristic Features I Medullary Endosteal disease II Superficial Cortical surface infected because of coverage defect III Localised Cortical sequestrum that can be excised without compromising stability IV Diffuse I, II and III plus mechanical instability before or after debridement.

19. Physiological class Class Host’s immune system Features A host Normal Immunocompetent with good local vascularity B host Compromised Local or systemic factors that compromise immunity or healing C host Prohibitive Minimal disability, prohibitive morbidity anticipated, poor prognosis for cure, treatment worse than disease

21. AP & lateral view of the left wrist show a lobulated osteolytic lesion with well-defined borders and surrounding sclerosis at the distal radius. Minimal expansion, mild periosteal reaction and soft tissue swelling are present.

22. Sclerosing osteomyelitis of the lower tibia. Note the bone expansion and marked sclerosis. Sequestrum at lower tibia
