Objective

This study was undertaken to identify pathological conditions within the population living at Atalla (1000-500 BCE), an important early village site and ritual center located in Huancavelica, Peru.

Materials

Articulated burials (N = 3) and commingled human remains excavated during the 2015 and 2016 field seasons.

Methods

Osteological remains were analyzed for macroscopic evidence of pathological changes.

Results

A case of bilateral proximal radioulnar fusion was observed in an Early Horizon (ca. 800 BCE) subadult skeleton (Individual 1). A differential diagnosis of this pathology supports congenital radioulnar synostosis (CRUS), a rare developmental condition. Enamel hypoplasia was also identified in the same individual.

Conclusions

Burial treatment of Individual 1 does not provide any indication that CRUS was afforded an exceptional social significance.

Contribution to Paleopathology

This example of CRUS is notable as it represents the second published archaeological case of CRUS from Peru and the earliest reported case globally.

Limitations of this Study

The osteological sample currently available from this site is limited.

Suggestions for Future Research

Increased fieldwork in this region is recommended to further clarify the distribution and social significance of CRUS in the prehistoric Andes.

秘鲁阿塔拉遗址早期地平线亚成人墓葬中的双侧先天性桡尺骨联结

 客观的

这项研究的目的是确定生活在阿塔拉（公元前 1000-500 年）人口的病理状况，阿塔拉是位于秘鲁万卡维利卡的一个重要的早期村庄遗址和仪式中心。

 材料

2015 年和 2016 年野外季节挖掘出的铰接式墓葬（N = 3）和混合人类遗骸。

 方法

对骨遗骸进行分析以获取病理变化的宏观证据。

 结果

在早期地平线（约公元前 800 年）亚成人骨骼（个体 1）中观察到双侧近端桡尺融合病例。这种病理学的鉴别诊断支持先天性桡尺骨性骨联症（CRUS），这是一种罕见的发育性疾病。在同一个体中还发现了牙釉质发育不全。

 结论

个体 1 的埋葬处理并没有提供任何迹象表明 CRUS 具有特殊的社会意义。

对古病理学的贡献

这个 CRUS 的例子值得注意，因为它是秘鲁第二个发表的 CRUS 考古案例，也是全球最早报道的案例。

本研究的局限性

目前可从该网站获得的骨学样本有限。

对未来研究的建议

建议增加该地区的实地考察，以进一步阐明史前安第斯山脉 CRUS 的分布和社会意义。
