This is a bruise and is caused by an impact with a hard object or pressure that causes the blood vessels under the skin to burst and blood to leak out into the cellular space. Typically appears as a range of colors in a localized area on the skin. Current literature states that bruises cannot be reliably dated. The most common question I am asked is whether or not you can date bruises. The short answer is no. Note: All of the studies mentioned were focused on children, there are other studies available for all ages. Driving Directions.

In this issue of the journal the possibility that heme oxygenase activity is responsible for the delay in the appearance of the yellow color in bruises has been investigated [ 1 ]. Bruises in the skin and subcutaneous tissues occur when there has been extravasation of blood following the application of blunt force. Generally the requirements for their formation are injury, compromise of the integrity of vessel walls, and blood pressure [ 3 ].
Age dating of bruises can often be determined by looking at the color of the bruise. The ages and colors of bruises may therefore show if more than one injury is.

Bruising is one of the most common types of soft tissue injury noted on victims of violence, including those suffering intimate partner violence, sexual assault, child abuse, and vulnerable adult abuse. Unidentified injuries can lead to a disparity in the forensic investigation of certain victims, particularly those who have darker skin color or delay seeking treatment. Clear documentation of injuries can support more successful prosecutions and victims who are more likely to engage in the criminal justice process.
The Department of Justice has recommended the use of alternate light to enhance bruise visualization. However, the technology has yet to be widely adopted in forensic examinations of violence victims likely due to 1 a knowledge deficit of the science behind alternate light among practitioners and 2 a dearth of research supporting its use. In this webinar, we reviewed the science of alternate light and bruising in ways readily usable for multiple disciplines for end-user testimony.
We then presented the major findings of a recently completed National Institute of Justice funded, multi-site, randomized controlled trial in which alternate light was compared to white light in the detection and visibility of inflicted bruises. Focused attention was given on skin color and other factors which were found to impact alternate light wavelengths performance.
Finally, recommendations for clinical application and medico-legal interpretation were discussed, including forensic photography. Alternate light is a practitioner-driven technology and has the potential to be a reliable, cost-effective, and rapid method to identify potential bruises in a variety of settings. Register Here.
Why Do Bruises Turn Colors?
assessment of colour which is not possible. There is Histological dating of bruises relies on a predictable characteristic of cellular responses; however data in.
The colors of a bruise appear courtesy of proteins being broken down inside the white blood cells. The first color is purple, which is caused by the hemoglobin being broken down and losing its oxygen. That happens immediately after the injury. The first breakdown product of hemoglobin is called biliverdin, which appears within a few days of the contusion and explains the greenish tint. The green biliverdin is then converted to a yellow molecule called bilirubin.
That process takes anywhere between a few days and several weeks, depending on the size of the bruise. Once bilirubin is made, it dissolves in the blood stream and is carried off to the liver and kidneys for final processing and excretion.
Bruising basics: What to do when you’re black & blue
As red blood cells degrade within a bruise, haemoglobin breaks down into bilirubin and biliverdin , and it is these pigments that pass through a series of colour changes. As these pigments resolve, the bruise changes in shape, size and location. Colour changes tend to begin at the margins of a bruise, and thus a large collection of blood will take comparatively longer to pass through a series of colour changes. Traditionally, opinion regarding the ‘age’ of a bruise was based in large part on the colour of the bruise, and authors of forensic textbooks gave their own suggested ‘timetable’ of colour changes with time summarised in Langlois and Gresham There appeared to be a ‘consensus’ view that red, blue and purple were ‘early’ colours, greens appearing after days and yellow making a late appearance after at least 7 days.
Yellow colouration appeared in bruises in calves, however, by 48 hours McCauseland and Dougherty
for single bruises from one episode of trauma to develop different colors in different areas at the same time. All of this tells us that dating of.
This digital download provides a fuller examination of the research related to the clinical assessment of bruises—the 1st portion of this clinical guide. I receive a lot of questions about determining the age of bruises. Although the research has shown that determining the age of bruising by clinicians based on color provides consistently inaccurate results, with poor interrater reliability , I still find that some are loathe to turn their backs on this highly unreliable assessment technique.
So I have provided an overview of the literature below, with articles split into 2 categories: those that address the attempt to age bruises based on color in a routine clinical environment Clinical Assessment of Bruises and those that have a much more high-tech approach Laboratory Assessment of Bruises. These articles address aging bruises using equipment and mathematical models not typically seen in our routine clinical practices.
The articles below address bruising in a wide range of populations. Some specifically address pediatrics; one specifically addresses older adults. Check your inbox or spam folder to confirm your subscription. Sign up for our Newsletter.
ageing bruising by visual assessment
A hematoma is a large collection of blood that becomes trapped within tissues. It is often related to more significant trauma. When a hematoma occurs, the body cannot heal the bruise as easily or quickly as a minor injury. As a result, a hematoma stays the same color, firmness, and causes the same level of pain even after several days.
