Abstract

The frequency, age distribution and development of supernumerary epiphyses in the hand and foot were radiographically documented in 98 macaque fetuses and infants. Extra epiphyses were observed only on distal metacarpal 1 and metatarsal 1, and were present in 15% of a cross-sectional sample and 20% of a longitudinal sample. They appeared coincidentally with the ossification of other secondary epiphyses of the hand and foot. Development of extra epiphyses in this species seems to be a normal phenomenon.

摘要

通过X线摄影记录了98只猕猴胎儿和婴儿手部及足部多余骨骺的出现频率、年龄分布和发育情况。仅在第一掌骨远端和第一跖骨远端观察到多余骨骺，在横断面样本中占15%，在纵向样本中占20%。它们与手部和足部其他次级骨骺的骨化同时出现。该物种多余骨骺的发育似乎是一种正常现象。
