Radial head subluxation (RHS) is the most common upper extremity injury in children. Supination-flexion (SF) and hyperpronation (HP) are two methods for reducing this subluxation. This study purposed to compare the success rates of two methods of reduction and also to determine which technique would be less painful. In total, 154 patients with RHS were enrolled in this study and randomized into two groups. Patients were to undergo reduction by one of the two methods; if the primary attempt was unsuccessful, a second attempt was performed using the alternate technique. In the case of failure of the second attempt, the first reduction technique was repeated. The success rates and pain levels before and after successful reduction were recorded. On the first attempt, 72 of 77 patients who underwent HP had a successful reduction. Four patients in the HP group had a successful reduction on the second attempt. In the SF group, 76 of 77 patients had a successful reduction on the first attempt. The success rate on first attempts was higher in the SF group than in the HP group ( = 0.043). Pain levels before and after reduction were not statistically different between the groups ( > 0.05). The SF technique had a higher success rate at first attempt to reduce RHS, but pain levels were similar in both methods.
桡骨头半脱位（RHS）是儿童最常见的上肢损伤。旋后-屈曲（SF）和旋前过度（HP）是两种复位这种半脱位的方法。本研究旨在比较两种复位方法的成功率，并确定哪种技术疼痛程度更低。本研究共纳入154例RHS患者，并随机分为两组。患者采用两种方法之一进行复位；如果初次尝试不成功，则使用另一种技术进行第二次尝试。如果第二次尝试失败，则重复第一次复位技术。记录成功复位前后的成功率和疼痛程度。在第一次尝试时，77例接受HP复位的患者中有72例成功复位。HP组有4例患者在第二次尝试时成功复位。在SF组，77例患者中有76例在第一次尝试时成功复位。SF组首次尝试的成功率高于HP组（P = 0.043）。两组复位前后的疼痛程度无统计学差异（P>0.05）。SF技术在首次尝试复位RHS时成功率更高，但两种方法的疼痛程度相似。
