intra-articular steroid injection
Direct injection of corticosteroids into affected joints as a targeted treatment for localized inflammation in pediatric arthritis.
Full Definition
Intra-articular steroid injection involves the direct administration of corticosteroids into inflamed joints to provide localized anti-inflammatory effects while minimizing systemic exposure. This procedure is commonly used in pediatric rheumatology for treating oligoarticular juvenile idiopathic arthritis, particularly when only a few joints are affected. The technique requires careful attention to sterile procedure and may be performed under sedation or general anesthesia in younger children. Common preparations include triamcinolone acetonide and triamcinolone hexacetonide, with the choice depending on joint size and desired duration of effect. Benefits include rapid symptom relief and avoidance of systemic medication side effects, though repeated injections may be associated with local complications.
