Intraarticular hip treatment with triamcinolonehexacetonide in juvenile chronic arthritis.

To evaluate the effect and tolerance of intraarticular Triamcinolonehexacetonide (TCH) in the course of chronic coxitis in juvenile chronic arthritis (JCA) in an open uncontrolled study. Since 1990 we treated patients < 16 years of age suffering from chronic coxitis with 1 mg/TCH/KG body weight. The patients were checked again 4-8 weeks after the treatment. Clinical and ultrasound courses were recorded with the help of ultrasound and joint scores. The evaluation took place 6, 12, 24 and 36 months after the treatment. At that time we give a report on the 12 months follow-up of 37 hip joints and the 24 months follow-up of 20 hip joints. The immediate effect of TCH influencing mobility, pain sensitivity and joint effusions of the patients is impressing. The long term effect of TCH has to be evaluated by regular check ups for at least 2 years. An individual comparison with the not treated contralateral joint would be desired if ethically justifiable. Most patients suffering from polyarticular diseases with a long course of coxitis needed more than one injection of TCH (mean reinjection time 5.8 months). Any avascular necrosis of the femoral heads or other complications were not observed.
