Defects or clefts may be seen in the growing epiphysis and are usually observed just before puberty. The basal epiphysis of the proximal phalanx of the great toe is the most common site but similar defects have been observed in a number of other epiphyses. At least some of these defects develop within a single normal appearing epiphysis and are not associated with signs or symptoms suggestive of fracture. The mechanism of formation of these defects is not clear. The defects probably close spontaneously sometime around late puberty.
在生长中的骨骺可能会出现缺损或裂隙，通常在青春期前被观察到。大脚趾近节趾骨的基底骨骺是最常见的部位，但在其他一些骨骺中也观察到了类似的缺损。这些缺损中至少有一些是在单个外观正常的骨骺内形成的，并且与提示骨折的体征或症状无关。这些缺损的形成机制尚不清楚。这些缺损可能在青春期后期的某个时候自发闭合。
