PUSTULOTIC ARTHROOSTEITIS ASSOCIATED WITH ACETABULAR CARTILAGE LESIONIN PUSTULOTIC ARTHROPATHY - IMPLICATION OF BONE-MARROW

We describe a case of pustulotic arthro-osteitis with hip joint involv ement. After right hip joint and walking did not improve despite drugs and physical therapy, total hip replacement was performed, During sur gery, brownish degenerated tissue was detected on the surface of the a cetabular side, Pathohistological examination revealed that granulatio n tissue caused by suppurative inflammation of the bone marrow had bro ken through the cartilage surface, reaching the superficial layer, Our findings suggest that hip joint lesions in pustulotic arthro-osteitis may originate from bone marrow lesions.
