A new technique of fixation of radial head fractures using a modified tubular plate.

ABSTRACT

Radial head fractures are fairly common, occurring in 17-44% of all elbow injuries. Mason Type 2 fractures may be fixed using mini fragment screws, this fixation often needing augmentation with a plate to make the construct rotationally stable. However, the drill holes needed to fix the plate to the radial head, carry the risk of inflicting more injury to the fractured fragments. In our case, the radial head fracture was fixed with a modified one-third tubular plate. The plate was cut through the distal hole and the two cut ends were bent into hooks. These two hooks were engaged into two breaches made on the margin of the radial head and this provided rotational stability to the head without causing further damage. The fracture healed well and the patient regained full movement in the elbow. We conclude that this method may be used to fix fractures of the radial head, which require additional support with a plate.
