Acute trauma: patterns in the peripheral skeleton
J. Teh; Oxford/GB
Learning Objectives

1. To become familiar with the imaging manifestations of common important injuries in the upper and lower limb.
2. To understand the underlying mechanism that result in combination of injuries.
3. To learn how to best employ imaging modalities in their diagnosis.

Abstract

A systematic approach to analysing trauma imaging of the peripheral skeleton is presented. Typically, imaging begins with x-rays. A step-wise approach may reveal subtle abnormalities that should prompt further action. For example, the presence of a Second fracture on x-ray suggests an ACL injury and thus should lead to an MRI scan. It should be recognised that in trauma, certain injuries cannot occur in isolation; therefore a dislocated radial head on elbow x-ray should prompt imaging of the whole forearm, as Monteggia fracture-dislocation may be present. Understanding mechanisms of injury allow the radiologist to predict patterns of injury. So if bone bruising is present on MRI in the lateral femoral condyle and medial patella, a lateral patellar dislocation should be suspected, and a specific search for an injury of the medial retinaculum should be made. Conversely, recognising classic patterns of injury can allow the mechanism of injury to be deduced. This lecture will focus on classical patterns of acute trauma in the peripheral skeleton.
