Radiologic Evaluation of the Distal End Radius Indices in Indian Paediatric Population

The distal end radius's bony anatomy in relation to three variables—Radial Inclination, Volar tilt, and radial height—has been discussed commonly in the adult population and is not very well defined in the growing skeleton. In children aged 8–16 years old, we measured the osseous distal end radius according to radiography standards. The research comprised 130 patients, 65 males and 65 females aged 8–16. In each child, the norms for radial inclination, volar tilt, and radial epiphyseal height were established. This research defines these radiographic parameters for the paediatric population in India for the first time.

This research is an Unicentric Cross-sectional observational analytical study. We studied 130 normal wrist posteroanterior and lateral radiographs of the Indian paediatric population aged 8–16 years who reported to our OPD and calculated the three parameters—(1) Radial height, (2) Volar Tilt, and (3) Radial Inclination. Mean measurement values were analysed statistically.

The Mean distal end radius volar tilt is 10.92° ± 1.76° SD with a range from 4° to 15°. The Mean distal end radial inclination is 21.04° ± 2.10° SD with a range from 15° to 25°. The Mean distal end radial height is 11.93 ± 1.44 mm SD with a range from 9.0 to 14.50 mm.

In true Postero-anterior and lateral wrist radiographs of the Indian paediatric population, we have established normal values that may be utilized as a guide for the evaluation and treatment of a variety of traumatic and non-traumatic problems in Indian children.
