摘要 副舟骨是较为常见的足部副骨,是由足舟骨之外的骨化中心成骨后未能与舟骨相融合而行成。其位于足舟骨结节内侧,表现为舟骨结节处的膨隆。大多数情况下,副舟骨没有症状,通常在行其他目的的足部影像学检查时得以发现,发生率占X线检查的4%~14%[1,2]。 根据X线检查的形态学表现,副舟骨可以分为3型[3,4]。I型副舟骨:呈卵圆形或圆形,形态非常规则,大小2~6 mm,与足舟骨之间无接触。此型副舟骨包埋于胫后肌腱远端之内,一般不产生症状。约占所有副舟骨的30%;Ⅱ型副舟骨:最为常见,占所有副舟骨的50%~60%,与足舟骨之间以1~2 mm的纤维软骨结合相连接;Ⅲ型副舟骨:三种副舟骨中最少见的类型,占10%~20%,副舟骨已与舟骨相融合,表现为增大的舟骨结节。
