Bumper fracture

A bumper fracture is a fracture of the lateral tibial plateau caused by the bumper of a car coming into contact with the outer side of the knee when a person is standing. Specifically, it is caused by a forced valgus applied to the knee. This causes the lateral part of the distal femur and the lateral tibial plateau to come into contact, compressing the tibial plateau and causing the tibia to fracture. The name of the injury is because it was described as being caused by the impact of a car bumper on the lateral side of the knee while the foot is planted on the ground, although this mechanism is only seen in about 25% of tibial plateau fractures.[1]

Fracture of the neck of the fibula may also be found, and associated injury to the medial collateral ligament or cruciate ligaments occurs in about 10% of cases.[2][3]

History

The term "bumper fracture" was coined in 1929 by Cotton and Berg.[4]

gollark: > This book is intended as a text for a second or third level undergraduate course in introductory ethical calculus or morality science. Ethical Calculus on the Astral Manifold demonstrates foundational concepts of ZFC+DMR axiomatic moral theory in particularly novel ways. Join an autonomous car as it journeys across the utility isosurface, restricted in phase-space by the physical constraints of spacetime. Follow the thought processes of the man at the lever in the modified manifold trolley problem. Watch as a eigenmoses maximizer behaves in a simulated environment, following an instinct one might find very familiar. These are just a few of many case studies presented, analyzed in detail in a manner both interesting, easy to read, and highly informative. Freshman knowledge of real analytical techniques is recommended but not necessarily required.

gollark: I see.
gollark: What do you mean "morally"? Have you devised some sort of formally specified typed encoding for ethics?
