Chronic limping in children usually indicates the presence of an underlying organic lesion. Clinical evaluation establishes the site and type of limping. It may suggest a neurological or mechanical lesion or locoregional etiology at the level of the hip or pelvis. Plain radiographs and ultrasound are firstline imaging techniques. The diagnosis may be delayed either due to ignorance of age-specific entities or false positive or negative results on plain films and ultrasound. MRI now plays a major role for diagnosis. Multiple potential underlying etiologies including trauma, infections, arthritides or tumors are best evaluated with MRI. The MRI examination should not be limited only to the hip joint.
儿童慢性跛行通常提示存在潜在的器质性病变。临床评估可确定跛行的部位和类型。它可能提示神经或机械性病变，或髋部或骨盆水平的局部病因。X线平片和超声是一线影像学检查技术。由于对特定年龄相关疾病的忽视，或X线平片和超声出现假阳性或假阴性结果，诊断可能会延迟。目前，磁共振成像（MRI）在诊断中发挥着重要作用。包括创伤、感染、关节炎或肿瘤在内的多种潜在病因，通过MRI评估最为理想。MRI检查不应仅限于髋关节。
