Distal Radius Measurements in Indian Population-An comprehensive Morphometrical Analysis

Abstract

The four basic morphometrical parameters regarding the anatomy of the distal end of radius bone are radial inclination, palmar tilt/volar tilt, radial height (length) and ulnar variance. The management of various conditions such as fracture of the distal radius bone, designing of the distal radius plates and kinesiology utilize the parameters in the morphometrical measurement of the distal end radius. The goal of our study is to bring about the normalized values of the morphometrical parameters of the DER among the general Indian population for helping in designing the distal radius plates. The study was conducted in a tertiary care hospital in India. It was a single hospital based study. The views considered for the study were the true posteroanterior (PA) and the lateral view (with neutral rotation). The posteroanterior view was used for the measurement of radial inclination, radial length (height) and the ulnar variance. The lateral view helped in the accomplishment of the measurement of the palmar/volar tilt. The statistical analysis was done by Microsoft Excel 2007 (Data add in function was installed for the analysis of the collected data). The means of the morphometrical parameters was compared with the help of T-test. Two hundred (n=200) radiographs were included for analysis under this study. The mean value of radial inclination was 20.7 8 ° ± (SD) 3.45° [Range: 14.9-29.1°], palmar/volar tilt 10.99° ± (SD) 3.87° [Range: 1.8-18.6°], radial length/height 11.39 mm ± (SD) 1.97 mm [Range: 8.3-27.7 mm], and ulnar variance 0.90 mm ± (SD) 3.14 mm [Range: +0.70 to +3.70]. This study will lead for further researches in the analysis of the morphometrical parameters of the distal end of radius bone in the Indian population. For the clinical management of the injuries around the wrist joint the results of this study can be used as a reference standard to anatomically align the bones and the affected structures.
