Importance of radial head on elbow kinematics: radial head prosthesis.

摘要

Dear sir,We would like to comment on the article by Wreten-berg et al. regarding radial head prosthesis after fracture of radial head with associated elbow instability. In the authors study, radial head prosthesis works well as a spacer and if the range of motion is much restricted post-operatively, the prosthesis can be removed for improving function . They advocate that the prosthesis extraction is due to the restriction in motion, which results from an overestimated size of prosthesis , The patient satisfied with the result after the radial head prosthesis extraction . The treatment of complex fracture of radius head with elbow instability is a common problem for an orthopedic surgeon. Various treatment options have appeared in the current literature 2-4.
