Most fractures of the radial head are stable undisplaced or minimally displaced partial
fractures without an associated fracture of the elbow or forearm or ligament injury, where …

Background Radial head arthroplasty is a common procedure in elbow surgery. It has been
shown to be of benefit for the patients, but there also are relevant complications that should …

Background Monopolar and bipolar radial head prosthetic arthroplasties have been used
successfully to treat elbow fracture-dislocation with unsalvageable radial head fractures. The …

Purpose To determine if radiocapitellar contact pressures would be elevated with
nonanatomical (circular) prostheses over those mimicking native anatomy and if such …

Background Posteromedial rotatory instability (PMRI) of the elbow consists of an
anteromedial coronoid fracture with lateral collateral ligament (LCL) and posterior bundle of …

Hypothesis Our aim was to test whether anatomically designed metallic radial head implants
could better reproduce native radiocapitellar contact pressure and areas than nonanatomic …

Background: Joint incongruity in posteromedial rotatory instability (PMRI) has been
theorized to determine early articular degenerative changes. Our hypothesis was that the …

Aims The aim of this study was to evaluate two hypotheses. First, that disruption of posterior
bundle of the medial collateral ligament (PMCL) has to occur for the elbow to subluxate in …

Introduction The role of bipolar radial head prostheses (RHP) in elbow fracture-dislocation is
controversial, with some reports of poorer stabilization than with monopolar designs. The …

Background Theoretical advantages of bipolar over monopolar radial head arthroplasty
include better accommodation of radiocapitellar malalignment, reduction of capitellar …
