Abstract： Objective： To observe the clinical effect of fumigation with Niubangzi tang combined with skin traction for transient synovitis of the hip(TSH) in children. Methods： A total of 60 cases of TSH children were selected as the study subjects， and were randomly divided into the treatment group and the control group according to different treatment methods，30 cases in each group. The control group was simply given skin traction，and the treatment group was additionally treated with fumigation with Niubangzi tang based on the treatment of the control group. Both groups were treated for 7 to 28 days. After treatment，the levels of ultrasound in the hip and the Harris Hip Score in the two groups were compared. Results： After one，two and four weeks of treatment respectively，children with normal ultrasound in the treatment group were more than those in the control group(P＜0.05)；Harris Hip Score was increased(P＜0.05). The total effective rate was 96.67% in the treatment group and 80.00% in the control group，the difference being significant(P＜0.05). Conclusion：Fumigation with Niubangzi tang combined with skin traction for TSH can effectively relieve pain in the hip，improve the elimination of synovial swelling in the hip and the absorption of joint effusion，and accelerate the recovery of hip joint function.
