Abstract
PAES, Andrey Cabral; MALLMANN, Ralff and DUARTE, Márcio Luís. Silicone Radial Head Prosthesis Fracture. Acta Radiol Port [online]. 2021, vol.33, n.1, pp.33-34. Epub July 16, 2021. ISSN 2183-1351. https://doi.org/10.25748/arp.18873.
The radial head is an important secondary stabilizer of the elbow and can bear up to 60% of the load transmitted from the forearm. Replacement of the radial head is advised in cases in which the extent of ligamentous injury calls for this secondary stabilizing function and it is not possible to reconstruct the radial head. The inability of a silicone radial head to resist compressive loads or valgus stress is evidence that the implant does not restore normal radiocapitellar load transmission, which is believed to be imperative for normal elbow function. We report a complication of the silicone prosthesis of the radial head diagnosed by computed tomography.
