-
摘要: ［摘要］目的 通过耻骨联合面形态变化推断年龄．方法 以我国南方人口为标本的研究目前为空白，通过以云南汉族男性为标本进行形态学观察，找到与其他地域人口在耻骨联合面形态变化上的不同，为下一步总结出适宜南方人群的年龄推断公式打下基础．结果 云南汉族男性耻骨联合面沟与嵴出现比文献资料报道的要早1～2岁，骨化结节出现率不高，国内的文献资料表明腹侧缘的出现始于27岁左右，至35岁完全形成并逐渐增宽，未见有隆起的报道，男性耻骨出现隆起；腹侧斜面变化比文献报道早1～2岁．结论 云南男性汉族耻骨联合面形态变化与年龄的关系确有一定的特殊性，某些指标的出现比国内其余人种要略早，一些指标出现率不高Abstract: ［Abstract］Objective To observe the morphology of symphysial surface in male Han people in Yunnan， and provide a evidence for finding a age estimation formula suitable to people in South of China．Method The morphology of symphysial surface in male Han people in Yunnan was observed．Results The pubic symphysis ditch and ridge of Yunnan Han male people appeared 1 to 2 years earlier than literatures reported， the appearance rate of ossifying nodules was not high．The domestic literature data showed that the ventral margin of emergence appeared at around age 27，fully formed to 35 years and gradually widened，there was no uplift reports，male pubic appeared uplift．The ventral surface changes appeared 1～2 years ealier than those reported in literature．Conclusion The relation between morphological change of symphysial surface and age has certain particularity in Yunnan male Han people，some indexes appear slightly earlier than domestic other people，the appearance rate of some indexes is not high
