A causal correlation is proved between an outgrowing osseous spur at the Os metacarpale II and the rhizarthrosis. The midhand bone of the thumb is connected by a ligament with the base of the Os metacarpale II. High tensile stresses elongate the ligament and lead to its partial ossification. The ligament looses its essential function and the thumb subluxates radially.
已证实第二掌骨处生长的骨赘与拇指掌指关节病之间存在因果关系。拇指的中间指骨通过韧带与第二掌骨基部相连。高拉伸应力会拉长韧带并导致其部分骨化。韧带失去其基本功能，拇指会向桡侧半脱位。
