Hip osteoarthritis is one of the most important and debilitating diseases affecting thousands of people all over the world. On the other hand, femoroacetabular impingement (FAI) is one of the known important causes of hip osteoarthritis. Cam deformity frequently presents in FAI showing an increased alpha angle. Increased alpha angle has been observed among young patients involved in demanding physical activities such as in sports (40-60%), whereas among the non-athletic population, increased alpha angle was observed in 15-20%. Although femoroacetabular pathology has been described over the recent years, it is not possible to determine when the angle increase actually begins prior to diagnosis. The aim of our study is to evaluate the femoral alpha angle in different human femurs in different civilization eras in West Mediterranean area.
Available ancient femurs were selected from the Collection Center belonging to the archeological archives (ancient necropolis) from the fourth, fourteenth and eighteenth centuries. A comparison of the alpha angle was made of the measurements from the different groups accompanied by a sample of present-day femurs from the radiology database of CT scans. Data from 243 femoral bones were collected, 50 of which from the fourth century, 26 from the fourteenth century, 68 from the eighteenth century, and 99 femurs from the 20/twenty-first century.
Alpha angles in all historical samples showed pathological values (> 55º) up to a maximum of 11.5% of the cases. Meanwhile, the actual series showed pathological alpha angle in 60.1% of the cases with statistical significant differences.
The studied femurs of the western Mediterranean region from the fourth, fourteenth and eighteenth centuries showed pathological alpha angles in a smaller proportion than the actual sample.

髋关节骨关节炎是全球数千人受其影响的最重要且使人虚弱的疾病之一。另一方面，股骨髋臼撞击症（FAI）是已知的髋关节骨关节炎的重要原因之一。在 FAI 中，经常出现凸轮畸形，表现为增大的 α 角。在从事高要求体育活动的年轻患者（40-60%）中观察到 α 角增大，而在非运动员人群中，α 角增大见于 15-20%。尽管近年来已经描述了股骨髋臼病理学，但在诊断之前，无法确定角度增加实际上何时开始。我们的研究旨在评估西地中海地区不同文明时代不同人类股骨的股骨 α 角。
从属于考古档案（古代墓地）收藏中心的可用古代股骨中选择了可用的股骨。对不同组别的 α 角进行了比较，并对来自当今 CT 扫描放射学数据库的股骨样本进行了比较。共收集了 243 个股骨数据，其中 50 个来自 4 世纪，26 个来自 14 世纪，68 个来自 18 世纪，99 个来自 20/21 世纪。
所有历史样本的 α 角均显示出病理性值（>55°），最高可达 11.5%的病例。同时，实际系列中 60.1%的病例存在病理性 α 角，差异具有统计学意义。
与实际样本相比，来自西地中海地区 4 世纪、14 世纪和 18 世纪的研究股骨的病理性 α 角比例较小。
