INTRODUCTION Comminuted radial head fractures (Mason type III) continue to pose a challenge to orthopedic surgeons. When internal fixation is not possible, radial head arthroplasty has been advocated as the treatment of choice. The purpose of this retrospective study was to evaluate clinical and radiological short-term results of patients with Mason type III radial head fractures treated with a...

It has been shown that the sensitivity and accuracy of orientation perception in the periphery is significantly better when the orientations are radial with respect to the fixation point than when they are tangential. However, since perception and action may be dissociated, it is unclear whether the perceptual radial effect has a counterpart in reaction time (RT) of motor responses. Furthermore...

BACKGROUND Radial-head subluxation is an easily identified and treated injury. We investigated whether triage nurses in the emergency department can safely reduce radial-head subluxation at rates that are not substantially lower than those of emergency department physicians. METHODS We performed an open, noninferiority, cluster-randomized control trial. Children aged 6 years and younger who p...

BACKGROUND Metal prostheses are useful for restoring elbow and forearm stability when the radial head cannot be fixed after a fracture. Because the anatomy of the radial head is difficult to reproduce with a prosthesis, two different options have been proposed: a bipolar prosthesis with a fixed stem and a mobile head, and a monoblock prosthesis with a smooth stem that is intentionally fixed loo...

BACKGROUND Radial head arthroplasty is commonly used to treat acute unreconstructible radial head fractures. The purpose of this study was to report on the clinical and radiographic outcomes at a minimum follow-up of five years after radial head arthroplasty with a modular metallic implant for the treatment of acute radial head fractures. METHODS The cases of fifty-five patients with unrecons...

The treatment of chronic radial head dislocation remains controversial. Open reduction of the radial head in combination with correction of malalignment with ulnar osteotomy can be the key to a good surgical result. Between 2001 and 2006, 9 (6 female, 3 male, average age 8.4 (5-11) years) patients were treated surgically for chronic radial head dislocation by one surgeon. The time between traum...

OBJECTIVE Analyze the results of unipolar modular radial head arthroplasty in the treatment of complex fractures associated with elbow joint instability. MATERIAL AND METHOD Retrospective design study of 44 patients, 17 men and 27 women with a mean age of 51 years (17-78) who suffered radial head fractures (Mason III) in the context of an unstable elbow injury. Mean follow-up was 21.2 months ...
