Abstract
The clinical success rate after PRFA of osteoid osteoma in children is relatively lower than in older patients. This may be attributed to greater technical difficulties during the procedure in children as well as their small body mass.
Intra-articular osteoid osteomas (IAOO) are infrequent in contrast to other locations and may be hard to detect and diagnose. They commonly present with vague symptoms and may be mistaken for inflammatory arthritis. They are most commonly found in the hip and can lead, particularly in long-standing cases, to irreversible articular cartilage damage. Thus, early diagnosis and management are of utmost importance.
The atypical radiologic signs of IAOO, such as the absence of sclerosis or calcified nidus, combined with other non-specific symptoms such as joint effusion and synovitis with collateral articular cartilage degradation or premature osteoarthritis, make the diagnosis even more problematic.
Treatment of IAOO is technically demanding because cartilage damage must be avoided. Moreover, entrance into the joint capsule to ablate such lesions is associated with a higher risk of developing infective arthritis. However, case series in the literature support the use of PRFA for the management of IAOO in unspecified age groups, suggesting that these lesions can be treated effectively as well. However, case reports of late articular damage have been reported.
