Arthroscopic Assisted Bioabsorbable Screw Fixation for Radial Head Fractures: A Report of Two Cases

ABSTRACT

Most radial head fractures occur as the result of low-energy mechanisms, such as a trip or fall on the outstretched hand. These fractures typically occur when an axial load is applied to the forearm, causing the radial head to hit the capitellum of the humerus. Good results are shown with nonsurgical treatments for Mason type 2 fractures. However, if there is a limitation of elbow joint exercise or displacement of more than 2 mm, an operative treatment should be considered. We treated two patients with arthroscopic assisted bioabsorbable screw (K-MET™; U&I Corporation, Uijeongbu, Korea) fixation for radial head fractures to prevent complications of open reduction and minimize radiation exposure.
