Three cases of a complex malformation of the hand involving syndactyly, polydactyly, and hypoplastic triphalangeal thumb are presented. In all three patients, six metacarpal bones and hypoplasticity of the thenar muscles were present. In one patient, both hands, except the most radial digits of the left hand, were completely fused by soft webs as reported by Haas and Ofodile. In two other patients, the extent of the webs differed from Haas's case, but one of them was similar to Ofodile's first case. In all instances the supernumerary digit had a triphalangeal configuration and the thenar muscles were hypoplastic, often associated with some degree of webbing.
本文报告了3例复杂的手部畸形病例，包括并指、多指和发育不全的三节指骨拇指。所有3例患者均有6块掌骨和鱼际肌发育不全。在1例患者中，如哈斯（Haas）和奥福迪尔（Ofodile）所报道，双手除左手最桡侧的手指外，均被软蹼完全融合。在另外2例患者中，蹼的范围与哈斯的病例不同，但其中1例与奥福迪尔的第1例相似。在所有病例中，多指均呈三节指骨形态，鱼际肌发育不全，常伴有一定程度的蹼状畸形。
