title: Effect of Intraarticular Triamcinolone Acetonide Injection for Wrist Pain in Rheumatoid Arthritis Patients: A Statistical Investigation.
abstract: A significant number of patients on long-term treatment and users of biologics complain of wrist pain due to synovial proliferation and arthropathic changes. Synovectomy or joint arthroplasty is often indicated for such patients, but many refuse surgery. For these patients triamcinolone acetonide was injected into the dorsum of the wrist, and evaluated the clinical benefit and safety of the wrist joint.
  
  
  
  We injected triamcinolone acetonide into the dorsum of the wrist. We evaluated the clinical benefit and safety of intraarticular triamcinolone acetonide by analyzing data on (1) the number of injections, (2) decrease in visual analog scale pain, (3) changes in carpal height ratio, radio carpal distance ratio, and radial rotation angle in X-ray imaging, and (4) the adverse reactions of triamcinolone acetonide injection on the subcutaneous tissue and extensor tendons.
  
  
  
  1. The number of injections per patient over 3 years 8 months was 1 for 44 wrists, 2 for 21 wrists, 3 for 17 wrists, 4 for 6 wrists, 5 for 3 wrists, 6 for 3 wrists, 7 for 2 wrists, 9 for 2 wrists, 12 for 4 wrists, and 13 for 1 wrist. 2. The overall mean VAS improved from 79 mm at baseline to 11 mm post-injection. 3. In the grade I and II group, CHS, RCDR and RRA were not statistically significant. In the grade III and IV group, CHR showed a significant decrease. 4. Neither subcutaneous atrophy nor extensor tendon rupture was reported.
  
  
  
  More than 90% of patients of all disease grades responded to an average of 1 to 4 injections per year.
