Reliability of Categorization of the Shape of the Lateral Edge of the First Metatarsal Head in Hallux Valgus

Radiographs of 128 feet of hallux valgus patients were evaluated by two foot and ankle surgeons and two radiologists on two separate occasions and the observers were asked to classify the first metatarsal head shape into three types (angular, intermediate, round) with circle measurements.

拇外翻（hallux valgus）患者的128足X线片由两名足踝外科医生和两名放射科医生在两个独立场合下进行评估，观察者需通过圆形测量法将第一跖骨头（first metatarsal head）的形态分为三种类型（角形、中间型、圆形）。
