Objective: To determine the frequency and types of joint deformities in children with juvenile idiopathic arthritis and their association with clinical parameters and rheumatoid factor. Study Design: Cross-sectional study. Place and Duration of Study: Rheumatology Outpatient Clinic, the Children's Hospital and the Institute of Child Health, Lahore, from September 2014 to February 2015. Methodology: All patients of both genders of less than 16 years of age, who fulfilled the International League of Association for Rheumatology (ILAR) criteria for Juvenile Idiopathic Arthritis (JIA), were enrolled in this study. Their demographic data, duration of disease at the time of presentation, types of JIA, various joint deformities and rheumatoid factor (RF) were documented. Statistical analysis of data was done on SPSS version 16. Chi-square test was applied to determine the association of clinical deformity with age of patients, disease duration at presentation, types of JIA and RF. Results: Out of 70 patients enrolled during the study period, 51.4% were boys with mean age at presentation being 9.44 ±3.89 years (2-7 years) and median duration of disease being 24 months (interquartile range 42 months). Forty patients (57.1%) had joint deformities. Most common joints involved were hand (50%), wrist (50%), and knee (35.7%). The common types of joint deformities were boutonniere deformity (28.6%), ulnar deviation of wrist (28.6%), fixed flexion deformity of wrist (22.9%), and knee (31.4%). The most common type of JIA was polyarthritis RF negative with or without deformity. There was a strong association of deformities with older age of patients at presentation (p=0.036), longer duration of disease at presentation (p=0.028), polyarthritis (RF seronegative / seropositive) (p=0.013), and seropositivity (p=0.04). Conclusion: More than 50% patients with JIA have joint deformities. Joint deformities are more likely to be seen in children with long-standing disease, those with polyarthritis JIA and seropositive patients.
