Abstract
1. The term "bumper fracture" is colourful but usually inaccurate. The injury is a valgus split or crush.
2. A series of sixty bumper fractures is reported: forty-eight were treated without operation or plaster.
3. Twenty-seven of the forty-eight patients treated without splintage have been followed up for more than five years, and seventeen of these for more than ten years.
4. The results are satisfactory and there is no evidence that there is any late deterioration of the joint.
5. It is suggested that bumper fractures should be treated without operation and without fixation in plaster.
