Background The important morphological parameters of distal radius namely palmar tilt, radial inclination, radial height and ulnar variance are consequential in the evaluation and management of the distal radius fracture, distal radius plate design and kinesiology. Correction of these parameters in anatomical alignment is important to restore the normal biomechanics of the wrist joint. Objective To ascertain the distal radius parameters in the patients attending tertiary care hospital with regard to gender and age. Method The wrist radiographs (postero-anterior and lateral views) of 125 patients, from 16 to above 60 years of age were used to determine the four parameters of distal radius. The subjects were divided into gender and three different age groups (16-36 years, 37-57 years and > 57 years). Independent t-test and ANOVA test was used for statistical analysis with level of significance set at p ≤ 0.05. Result The mean palmar tilt was 15.69 ± 4.84° (p-value = 0.40). The mean radial inclination was 22.58 ± 2.82° (p-value = 0.88). The mean value of radial height was 10.31 ± 1.59 mm (p-value= 0.001). Positive ulnar variance were recorded in maximum of subjects (46.40%) and the least was neutral (16.80%). Conclusion The distal radius parameters of our population were similar to the Orthopedic Trauma Association standard reference value. And there was significant difference in radial height between males and females.
桡骨远端的重要形态学参数，即掌倾角、桡骨倾斜角、桡骨高度和尺骨变异，在桡骨远端骨折的评估与治疗、桡骨远端钢板设计及运动学方面都很重要。将这些参数矫正至解剖学对线对于恢复腕关节的正常生物力学至关重要。目的：确定在三级医疗机构就诊的患者中，桡骨远端参数在性别和年龄方面的情况。方法：使用125例年龄在16岁至60岁以上患者的腕部X线片（正位和侧位）来确定桡骨远端的四个参数。研究对象被分为性别组和三个不同年龄组（16 - 36岁、37 - 57岁和>57岁）。采用独立t检验和方差分析进行统计学分析，显著性水平设定为p≤0.05。结果：平均掌倾角为15.69±4.84°（p值 = 0.40）。平均桡骨倾斜角为22.58±2.82°（p值 = 0.88）。桡骨高度的平均值为10.31±1.59 mm（p值 = 0.001）。记录到尺骨变异为阳性的受试者最多（46.40%），最少的是中立型（16.80%）。结论：我们研究人群的桡骨远端参数与骨科创伤协会的标准参考值相似。男性和女性在桡骨高度上存在显著差异。
