Morphometry of distal end radius in the Indian population: A radiological study

Abstract

Introduction:The morphometry of distal end radius (DER) comprises the four necessary parameters: radial inclination, palmer tilt, radial height, and ulnar variance. The unblemished intellect about the morphometry is urged for the management of fracture of DER. The goal of our study was to determine the values of morphometric parameters of the DER from the adult Indian.Materials and Methods:It was a single hospital- based observational cross-sectional, prospective study. Radial inclination, radial height, and ulnar variance were measured on posteroanterior view, and the measurement of palmer tilt was accomplished on the lateral view. All the statistical analysis was done by Microsoft XL 2007 (data add in function were installed for data analysis). T-test was used for comparing the means of the parameters.Results:Two hundred and forty two (n = 242) X-rays were included in this study to analyze. The mean value (n = 242) of radial inclination was 23.27°± (standard deviation [SD]) 7.42° (range: 11.3–42.1°), palmer tilt 10.07° ± (SD) 5.28° (range: 1–16.9°), radial height 11.31 mm ± (SD) 4.9 mm (range: 7.1–30.4 mm), and ulnar variance 0.66 mm ± (SD) 2.46 mm (range: −2.4 to +4.1).Conclusion:This study may provide an inauguratory plinth to prosecute the further analytical research in the Indian population. Moreover, the data may also be used as a reference data for the anatomical alignment while treating the injuries of the DER in the Indian population.

A study of the radiographic morphometry of the distal radius in a south Indian population

“…Chan et al [2] observed that the mean ulnar variance was a positive variance of 0.13 ± 0.72mm. Mishra et al [11] in their study of the Indian population observed a positive ulnar variance if 0.66 ±2.46mm [10]. However in our study there was a higher tendency was negative ulnar variance (Tables 6,7).…”

“…In our study, only the radial height showed a statistical difference between the male and female population. Mishra et al also ob- served a similar statistical difference in the radial height between genders [11]. The earliest effect of malunited distal radius fractures, on the normal biomechanics of the wrist joint, was described by Gartland and Werley in 1951 [8].…”

“…A negative variance was observed in 108 patients (34.8%) and positive variance was observed in 26 patients (8.4%). The OTA reference value for ulnar variance is the neutral variance [8,11]. Chan et al [2] observed that the mean ulnar variance was a positive variance of 0.13 ± 0.72mm.…”

“…Hadi et al published that the mean radial height in the Indonesian population was 11.31 ± 1.66 mm [9]. The OTA reference value is 1.1 to 1.3cm [8,11].…”

Radiologic Assessment of Angular Wrist Parameters of Asymptomatic Nigerians

“…Nevertheless, these difficulty will be reduced when country specific normative data are made available. [14,21] Capitolunate angle and scapholunate angle In this study, the CLA and SLA had a range of 14º to 22º and 35º to 55º respectively, which fell within the normal range reported by Gilula and Chesaru and Tischler et al [7,22] Values above the reported range suggests a scapholunate advanced collapse is characterised by abnormal increase in the scapholunate interval and forward movement of the capitate bone and characteristic tilting towards the dorsum of the scaphoid bone (Chang et al, 2014). [23] Radial tilt This studied population had a radial tilt range of 10-21º which was within the normal range of 11º (range; 2-20°) reported by Smithuis.…”
