Rotatory displacement of the atlantoaxial joint is one of the causes of torticollis in children. Some of these cases show persistent symptoms and may lead to rotatory fixation; however, only a few studies have been directed to the prognosis of atlantoaxial rotatory displacement after conservative treatment. Clinical and radiographic reviews were performed in 35 patients (16 male and 19 female) with rotatory displacement of the atlantoaxial joint. The mean age at admission was 6.5 (range: 2-12) years old, and the mean follow-up period was 3.4 (1.4-5.8) years. All patients successfully achieved reduction after 2 to 3 weeks of continuous halter traction; however, 9 patients (25.7%) experienced recurrence, and 7 patients (20.0%) had a slight torticollis at follow-up. The duration of symptoms before treatment affected the recurrence rate, and the torticollis was apt to remain in cases with severe displacement at admission.
寰枢关节旋转移位是儿童斜颈的病因之一。其中一些病例症状持续，可能导致旋转固定；然而，仅有少数研究针对保守治疗后寰枢关节旋转移位的预后。对35例寰枢关节旋转移位患者（男16例，女19例）进行了临床和影像学评估。入院时的平均年龄为6.5岁（范围：2至12岁），平均随访期为3.4年（1.4至5.8年）。所有患者在持续颌枕牵引2至3周后均成功复位；然而，9例患者（25.7%）复发，7例患者（20.0%）在随访时有轻度斜颈。治疗前症状持续时间影响复发率，入院时严重移位的病例中斜颈易于残留。
