Abstract
INTRODUCTION: Hip transient synovitis (TS) is a common pediatric orthopaedic problem. Although a self-limiting illness, it often makes the patient temporarily disabled and poses a diagnostic difficulty because of its similarity to septic arthritis in clinical manifestations. The aim of this study was to evaluate the use of a single ultrasound-guided hip aspiration as a treatment modality for TS.
METHODS: Between the years 1984 and 1989, 112 children with TS were treated through bed rest and using nonsteroidal anti-inflammatory drugs (group 1). Between the years 1990 and 1999, 119 children diagnosed with TS were treated using hip aspiration, bed rest, and nonsteroidal anti-inflammatory drugs (group 2). Recovery parameters were compared between these patient groups.
RESULTS: Twenty-four hours after admission, limping was noted in 92% and 10% of the patients in groups 1 and 2, respectively, (P < 0.001). Refusal to bear weight was observed in 14% and 1% in groups 1 and 2, respectively, (P < 0.001), and hip joint pain was reported in 81% and 6% in groups 1 and 2, respectively, (P < 0.001). Larger joint effusions were found to be the reason behind the inability to bear weight.
CONCLUSIONS: Pain due to TS may be because of capsule stretching owing to the accumulation of joint effusion. Ultrasound-guided hip aspiration relieves pain and limitation in movement and provides rapid differential diagnosis from septic arthritis of the hip joint.
