Optimal Screw Orientation for Fixation of Coronoid Fractures

Abstract

PA screw placement was biomechanically superior to AP screw placement. Together with the fact that it is clinically easier to insert and remove screw from the posterior ulna, these data indicate that optimal screw orientation for fixation of coronoid tip fracture is posterior to anterior direction.

The Biomechanical Effect of Prosthetic Design on Radiocapitellar Stability in a Terrible Triad Model

“…The coronoid was then fixed using a 2.7-mm, self-tapping, cortical screw inserted from posterior to anterior as a lag screw. 18 A pilot hole was drilled to facilitate screw insertion. A non-instrumented screwdriver was used to manually insert the lag screw.…”

Objective Analysis of Lateral Elbow Exposure with the Extensor Digitorum Communis Split Compared with the Kocher Interval

“…Coronoid fixation through an extended lateral approach is our preferred method. Fixation can be obtained successfully with use of retrograde posterior-to-anterior screws 26 or a suture lasso technique 22 .…”

Arthroscopic reduction and fixation of coronoid fractures with an exchange rod—a new technique

“…This operation is more challenging, since it is difficult to accurately guide the Kirschner wire into its ideal position in the fracture fragment. However, arthroscopy can make accurate positioning of the wire and insertion of the screw easier [23].
