Retrospective Assessment of Malleolar Injury Mechanism in an Impact Environment
Welcome to our study. We are aiming to investigate the value and reproducibility of ankle fracture classification systems in the impact environment and are looking for Orthopaedic Surgeons to participate.
This study by Dr. Bala Srinivasan and Dr. Jane Madeley, Orthopaedic Research Fellows, Automobile Safety Laboratory, University of Virginia/Orthopaedic Research Fellows, University of Nottingham, seeks to examine:
METHODS/INSTRUCTIONS
 | The questionnaire consists of X-rays and soft tissue injury reports for 9 cases of experimentally produced malleolar fractures where the mechanism of injury is known. |
| Please complete as many cases as you can, each case should take approximately 5 minutes. You are welcome to return to the site |
| Each individual's responses will remain anonymous, however we do ask you to enter identification details to allow us to match responses and examine intra observer variability. |
| After completing each case click "submit", which will store the information to our database. |
BACKGROUND
In order to improve the protection against sustaining malleolar fractures in motor vehicular accidents, we have to understand the mechanism of malleolar fracture generation in an impact environment. In most of the retrospective accident research studies reported in the literature, clinicians sought to infer the mechanism of injury from x-ray. This is based on the Lauge-Hansen mechanistic classification linking ankle injury mechanisms with radiographic fracture patterns. De Smet (1982), in a clinical review, found that radiographs alone to be imperfect predictor of injury mechanism. It has been shown that there is significant intra and inter observer variability with Lauge-Hansen classification (Nielson et al., 1990, Thomsen et al., 1991), casting further doubts on the ability of specialists to accurately infer fracture mechanism.
REQUIREMENTS
