- Abstract:
- Objective To quantitatively analyze the anatomical symmetry of bilateral proximal radii in adults based on threedimensional
morphological measurement. Methods The anatomical data of the left and right proximal radii for threedimensional
reconstruction were extracted from computed tomography scans of 15 normal individuals. After that both bone
volume and surface area of the left and right proximal radii models were measured, the anatomical symmetry between the
right and left proximal radii were quantified and visualized using three-dimensional deviation analysis. Results The mean
percentage difference in bone volume between the left and right proximal radii was 4.43%±3.90% (P=0.595), and that in
surface area was 2.79%±2.41% (P=0.321). The results of the three-dimensional deviation analysis showed that the
mean±standard deviation of the maximal negative deviation was (-1.14±0.41) mm, while that of the maximal positive
deviation was (1.00±0.37) mm. Moreover, the relatively high deviations were mainly distributed in those regions which
were away from the joint facets. Conclusion The bilateral proximal radii in adults show an excellent anatomical symmetry,
which satisfies the clinical requirements and provides a reliable basis for proximal radial fracture reduction guided by the
morphological model of the contralateral proximal radius. In the treatment of complex fractures involving the articular
surface of proximal radii, the preoperative planning that combines computer-aided and three-dimensional printing
technologies will effectively increase the benefits for the patients.
