Background: Transient hip tenosynovitis is one of the common causes of pain and limping in children and includes 0.4% to 0.9% of admissions in emergency wards. The aim of this study is to evaluate this disease in terms of clinical presentations, age and sex distribution, and six-month recurrence. Materials and Methods: In this cross-sectional study, 51 children with diagnosis of transient hip tenosynovitis were investigated. Inclusion criteria were physician's clinical suspicion of acute tenosynovitis according to clinical presentations, physical exam, and age range of 3 to 8 years. Results: Among the 51 children with tenosynovitis, 34 patients were male with age of 61.70±19.1 months and 17 patients were female with mean age of 48.35±20.49 months that presented a significant statistical difference (p=0.026). The most common complaint was hip pain and the most commonly involved joint was the hip. Also, most of the patients had the history of viral diseases. Conclusion: Transient hip tenosynovitis is more common in boys. The right hip is the most involved joint and the majority of patients have the history of recent viral diseases.
