Deformation of the distal radioulnar ligament during rotation using finite element analysis
The distal radioulnar ligament (DRUL) is a known stabilizer of the distal radioulnar joint (DRUJ) during rotation. However, the mechanism by which the radius is supported by the palmar and dorsal parts of DRUL during rotation remains controversial. Although many studies using fresh cadaver specimens...

| description | The distal radioulnar ligament (DRUL) is a known stabilizer of the distal radioulnar joint (DRUJ) during rotation. However, the mechanism by which the radius is supported by the palmar and dorsal parts of DRUL during rotation remains controversial. Although many studies using fresh cadaver specimens have been conducted to elucidate this mechanism, only few attempts have been made using computational analysis. Accordingly, the objective of this study was to analyze deformation of DRULs (four bundles: superficial palmar, deep palmar, superficial dorsal, and deep dorsal) during rotation using the finite element method. A three-dimensional forearm model was constructed from two bone models (radius and ulna) and models of four bundles connecting them. The radius was rotated around the axis line connecting the center of the distal ulna and the center of the proximal radius. The extension ratio of the superficial and deep bundles of the palmar DRUL increased during supination, while that of the dorsal DRUL increased during pronation. Furthermore, the extension ratio of the superficial bundles was larger than that of the deep bundles, indicating that the superficial bundles play a larger role in stability of the DRUJ than the deep bundles. The result of this study was qualitatively consistent with the experimental data of Schuind. The superficial and deep bundles on either side were taut together and simulated a single bundle. This was in opposition to the result of Hagert that the superficial and deep bundles deform in opposite ways. |
