Background and objectives Morphometric parameters such as radial inclination, palmar tilt, radial height, and ulnar variance exhibit considerable variations influenced by geographical, ethnic, racial, and individual factors. These parameters are pivotal in the context of distal radius fractures, distal radius plate design, and kinesiology. Understanding these variations is crucial for surgical precision and predicting complications. Methods This observational, retrospective study, conducted in a single hospital, aimed to determine the morphometric values of the distal end radius, specifically in the South Indian population. We analyzed 300 plain radiographs, encompassing 53.7% males and 46.3% females, with ages ranging from 17 to 89 years (mean age: 41.05 ± 15.8). Radial inclination, radial height, palmar tilt, and ulnar variance were measured on posteroanterior views, while palmar tilt was assessed on lateral wrist X-rays. Results In our study, significant gender-based and side-specific differences were observed. The mean length of the styloid process, palmar tilt, ulnar variance, anteroposterior diameter of the radius, transverse diameter of the radius, oblique width of the radius, and carpal height of the radius exhibited notable variations between males and females. Similarly, significant differences were noted between the right and left sides concerning ulnar variance and teardrop angle. Among males, a significant difference was observed only in the teardrop angle between the right and left sides (59.11 ± 7.25 vs. 62.01 ± 7.97). Conclusion The findings underscore the importance of recognizing local morphometric variations in the South Indian population. This knowledge not only enhances the ability to restore normal alignment post-distal radius fractures but also provides fundamental values for future research endeavors within the local demographic. The study acts as a foundational resource for advancing our understanding of the normal anatomy and variations in the distal radius, facilitating improved clinical outcomes and tailored surgical interventions.
诸如桡骨倾斜度、掌倾角、桡骨高度和尺骨差异等形态测量参数受地理、种族、民族和个体因素影响，存在相当大的差异。这些参数在桡骨远端骨折、桡骨远端钢板设计和运动学方面至关重要。了解这些差异对于手术精度和预测并发症至关重要。方法：本项在一家医院开展的观察性回顾性研究旨在确定桡骨远端的形态测量值，特别是在南印度人群中。我们分析了300张普通X线片，其中男性占53.7%，女性占46.3%，年龄范围为17至89岁（平均年龄：41.05±15.8）。在正位片上测量桡骨倾斜度、桡骨高度、掌倾角和尺骨差异，而掌倾角则在腕关节侧位X线片上评估。结果：在我们的研究中，观察到了显著的性别和侧别差异。茎突的平均长度、掌倾角、尺骨差异、桡骨的前后径、桡骨的横径、桡骨的斜径和桡骨的腕骨高度在男性和女性之间表现出明显差异。同样，在尺骨差异和泪滴角方面，左右两侧也存在显著差异。在男性中，仅在左右两侧的泪滴角上观察到显著差异（59.11±7.25对62.01±7.97）。结论：研究结果强调了认识南印度人群局部形态测量差异的重要性。这些知识不仅增强了桡骨远端骨折后恢复正常对线的能力，还为当地人群未来的研究工作提供了基础值。该研究是推进我们对桡骨远端正常解剖结构和变异理解的基础资源，有助于改善临床结果和进行个性化手术干预。
