Computer simulation of forearm rotation in angular deformities: a new therapeutic approach

Radial Head Dislocation During Proximal Radial Shaft Osteotomy

“…2e4 Computer simulations can predict the amount of rotational impairment caused by angular deformities in the forearm. 5 Miyake et al 6 reported results using a 3-dimensional simulation program and custom-made osteotomy template for malunited diaphyseal forearm fracture. They encountered no proximal radioulnar instability, but they found 2 cases of persistent instability of the distal radioulnar joint in patients who had instability before the osteotomies.…”

“…. ), et la gravité des cals vicieux qui peuvent les affecter, est bien connue [22][23][24][25]. Durant la rotation du radius autour de l'ulna, la géométrie des deux os fait que la distance entre les points d'insertion des fibres de la MIO varie : certains points se rapprochent (les fibres se détendent), tandis que d'autres s'éloignent (les fibres se tendent).…”

A morphological approach to the simulation of forearm motion

“…Based on MRI findings, more comprehensive kinematic models were developed that include the motion of the ulna [5], [6]. Kasten, Weinberg et al introduced a surrogate mechanism for the pro-/supination where the influence of This work has been supported by the Swiss National Science Foundation joints were taken into account by a simplified mechanical analogy [6], [7]. The fitting of kinematics to patient-specific anatomy was manually performed by measuring geometric attributes from radiographs, for instance bone lengths.…”
