Abstract
Osteoarthritis (OA) is a prevalent condition in horses, leading to changes in trabecular bone structure and radiographic texture. Although fractal dimension (FD) and lacunarity have been applied to quantify these changes in humans, their application in horses remains nascent. This study evaluated the use of FD, bone area fraction (BA/TA), and lacunarity in quantifying trabecular bone differences in the proximal phalanx (P1) in 50 radiographic examinations of equine metacarpophalangeal joints with varying OA degrees. In the dorsopalmar view, regions of interest were defined in the trabecular bone of the proximal epiphysis, medial and lateral to the sagittal groove of P1. Lower BA/TA values were observed medially in horses with severe OA (P=0.003). No significant differences in FD and lacunarity were found across OA degrees (P>0.1). FD, BA/TA, and lacunarity were not effective in identifying radiographic texture changes in the P1 trabecular bone in horses with different metacarpophalangeal OA degrees.
骨关节炎(OA)是马的一种常见病,会导致骨小梁结构和放射纹理发生变化。虽然分形维度(FD)和裂隙度已被用于量化人类的这些变化,但它们在马匹中的应用仍处于起步阶段。本研究评估了分形维度、骨面积分数(BA/TA)和裂隙度在量化近节指骨(P1)骨小梁差异中的应用,共对 50 例不同 OA 程度的马掌指关节进行了射线检查。在背侧视图中,在近端骨骺的骨小梁、P1矢状沟的内侧和外侧定义了感兴趣区域。在严重OA马的内侧观察到较低的BA/TA值(P=0.003)。不同OA程度的马在FD和裂隙度方面没有明显差异(P>0.1)。FD、BA/TA和裂隙度不能有效识别不同掌指关节OA程度马匹P1骨小梁的放射纹理变化。
