To determine prevalence and significance of abnormal superficial abdominal reflexes (SARs) in idiopathic scoliosis. Study of 73 patients with presumed idiopathic scoliosis referred for magnetic resonance imaging (MRI), either as a routine pre-operative assessment (n=42) or because of abnormal symptoms or neurological signs (n=31). All patients were examined prior to magnetic resonance imaging (MRI), and the presence of abnormal SARs was noted. All patients then underwent MRI of the whole spine from the foramen magnum to the sacrum. The presence of Chiari 1 malformation and syrinx was recorded. The study group consisted of 11 males and 62 females with a mean age at time of MRI of 18 years (range 5-51 years) and a mean Cobb angle of 48 degrees (range 10-104 degrees). Abnormality of the SARs was recorded in eight cases (prevalence 11%). An abnormal MRI study was recorded in nine cases (12.3%), all patients having a syrinx and four having in addition, a Chiari 1 malformation. Of the patients with abnormal SARs, only 2 (25%) had an abnormal MRI study; 1 had unilateral absence of the reflexes whereas the other had complete absence of SARs. Of patients referred for MRI as a routine pre-operative assessment, 5 (11.6%) had an abnormal MRI study. In patients with idiopathic scoliosis, abnormality of the SARs was recorded in 11% of cases. Unilateral absence was present in one case only and was associated with the presence of syrinx. Other patterns of abnormality were not a useful indicator of underlying cord abnormality.
确定特发性脊柱侧凸中异常腹壁浅反射（SARs）的患病率及其意义。对73例疑似特发性脊柱侧凸患者进行研究，这些患者因磁共振成像（MRI）检查前来就诊，其中42例是作为常规术前评估，31例是因为出现异常症状或神经体征。所有患者在进行磁共振成像（MRI）检查前均接受检查，并记录异常SARs的存在情况。然后所有患者均接受了从枕骨大孔至骶骨的全脊柱MRI检查。记录Chiari 1畸形和空洞的存在情况。研究组包括11名男性和62名女性，MRI检查时的平均年龄为18岁（范围5 - 51岁），平均Cobb角为48度（范围10 - 104度）。8例患者记录有SARs异常（患病率11%）。9例患者（12.3%）MRI检查异常，所有患者均有空洞，4例还伴有Chiari 1畸形。在SARs异常的患者中，只有2例（25%）MRI检查异常；1例为单侧反射缺失，另1例为SARs完全缺失。在作为常规术前评估而接受MRI检查的患者中，5例（11.6%）MRI检查异常。在特发性脊柱侧凸患者中，11%的病例记录有SARs异常。仅1例存在单侧缺失，且与空洞的存在相关。其他异常模式并非潜在脊髓异常的有用指标。
