Abstract

Fractures of long bones in limbs are rare traumatic events in horses. This study investigates whether the incidence and types of fractures can be related to the histomorphometric features of the radius and tibia, which experience different biomechanical stresses and exhibit varying incidences and types of fractures. Clinical observations suggest that, in adults, slightly transverse and comminuted fractures are present in the radius, while the tibia shows a higher frequency of longitudinal and spiral fractures. Microscopic observations reveal no apparent distinctive characteristics between the radius and tibia, whereas the histomorphometric data highlight differences in the osteon density, eccentricity, and diameters of the osteons and Haversian canals. To sum up, tibial osteons are more numerous and smaller than those in the radius, resulting in a 15% higher total extension of the cement line in the tibia compared to the radius. These histomorphometric differences are an evolutionary adaptation to the different biomechanical stresses that involve the thoracic and pelvic limbs. Our results could help better understand numerous clinical realities detectable through retrospective analyses and aid in evaluating a specific bone's predisposition towards traumatic events in all mammals, including humans.

骨组织形态计量与骨折之间是否存在关系?以马的桡骨和胫骨为例。
四肢长骨骨折是马罕见的创伤事件。桡骨和胫骨承受着不同的生物力学应力,其骨折的发生率和类型也各不相同,本研究探讨了这两种骨骼的组织形态特征是否与骨折的发生率和类型有关。临床观察表明,成人桡骨的骨折多为轻微横断和粉碎性骨折,而胫骨的骨折多为纵断和螺旋形骨折。显微镜观察显示,桡骨和胫骨没有明显的不同特征,而组织形态计量学数据则突出显示了骨质密度、偏心率以及骨质和哈弗氏管直径的差异。总之,胫骨的骨隆比桡骨的骨隆更多更小,因此胫骨骨水泥线的总延伸率比桡骨高15%。这些组织形态学上的差异是一种进化适应,以适应涉及胸腔和骨盆肢体的不同生物力学压力。我们的研究结果有助于更好地理解通过回顾性分析发现的许多临床现实,并有助于评估包括人类在内的所有哺乳动物的特定骨骼对创伤事件的易感性。
