Polydactyly may be preaxial or tibial (hallux-side), postaxial or ulnar (side of the little toe) and central (middle toes). The duplication may appear at the distal and medial phalanges or at the whole digit. The metatarsal bone may be part wise or completely duplicated, the accessory toes may share only one metatarsal. Surgical intervention may be indicated in shoe problems, for esthetic reasons or, especially in duplication of the metatarsales, because of secondary deviation of the toes and therefore shoe problems or plantar callosities. Preoperative analysis including x-ray is of great importance to achieve good functional and cosmetic results.
多指畸形可分为轴前型或胫侧型(拇趾侧)、轴后型或尺侧型(小趾侧)以及中央型(中间脚趾)。多指重复可能出现在远节和中节指骨,也可能累及整个手指。跖骨可能部分或完全重复,副趾可能仅共用一根跖骨。因穿鞋问题、美观原因,尤其是在跖骨重复的情况下,由于脚趾继发偏斜进而导致穿鞋问题或足底胼胝,可能需要进行手术干预。术前包括X线在内的分析对于获得良好的功能和美观效果至关重要。
