Abstract：
We examined the remains of an individual who was unearthed from the Tuchengzi site and was believed to be from the Warring States period in China. The remains exhibited segmental femoral fracture. We aimed to deduce the cause of fracture, medical interventions, healing process, and motion behavior after fracture healing using several techniques, including macroscopic observation, computed tomography (CT), and finite element analysis. Based on the morphology of the long bones, it appeared that the individual was male. The fractures resulted in an adduction angle of 5.47° and an anterior flexion angle of 21.34° in the proximal femur, while the femoral neck anteversion angle had been replaced by a retroversion angle of 10.74°. Additionally, the distal femur formed an abnormal anterior convex angle of 144.60°. CT revealed mature callus formation and visible trabecular bundles. The finite element analysis indicated that the maximum von Mises stress in the femur was 17.44 MPa during standing and 96.46 MPa during walking. We suggest that medical practitioners in the Warring States period possessed a good knowledge of thigh anatomy, enabling them to perform fracture reduction and fixation. Reasonable medical intervention facilitated fracture healing and load recovery. Satisfactory fracture healing ensured that the individual could engage in normal standing and walking activities after rehabilitation.
摘要：
我们检查了从土城子遗址出土的一个人的遗骸，据信他来自中国战国时期。遗骸表现为股骨节段性骨折。我们的目的是推断骨折的原因,医疗干预,愈合过程，和骨折愈合后的运动行为，使用几种技术，包括宏观观察，计算机断层扫描（CT），有限元分析。根据长骨的形态,似乎这个人是男性。骨折导致股骨近端内收角度为5.47°，前屈角度为21.34°，而股骨颈前倾角已被10.74°的后倾角所取代。此外,股骨远端形成144.60°的异常前凸角。CT显示成熟的愈伤组织形成和可见的小梁束。有限元分析表明，站立时股骨最大vonMises应力为17.44MPa，行走时最大vonMises应力为96.46MPa。我们建议战国时期的医生对大腿解剖有很好的了解，使他们能够进行骨折复位和固定。合理的医疗干预有利于骨折愈合和负荷恢复。满意的骨折愈合确保个体在康复后能够进行正常的站立和行走活动。
