Avulsion fractures ppt ashley and sarah musculo
By Ashley Knott and Sarah
An avulsion fracture occurs when there is an injury
to the bone where there is a tendon or ligament
attaching to it.
When the fracture occurs, the tendon or ligament
pull off the bone, making a fracture in the bone.
An avulsion fracture (of the hip) most commonly
occurs in adolescents, most often athletes. The
most common athletes that experience avulsion
fractures are track participants, especially hurdlers
The person will experience severe pain and there
will be visible swelling in the area of the fracture.
They will be unable to move that area of their body
without a great deal of pain.
Avulsion Fractures can be diagnosed by taking an
x-ray, and the x-ray may show a broken bone
If they are unable to see the avulsion fracture on
an x-ray and ultrasound may be done.
The best way to diagnose the severity and exact
area of the fracture is by taking an MRI.
Here you can see a piece of the bone
broken off but still attached to the muscle.
When patients experience an avulsion fracture (of
the hip), it is described as a feeling of an
unexpected, explosive muscle contraction.
This can also be described as a “kicking –out” of
the muscle at the end of a race for a runner if they
are experiencing an avulsion fracture.
Common symptoms experiences with an Avulsion
◦ Sudden onset of hip pain, usually very sever, sharp and
◦ Occur with a sudden burst of intensity (for example, with
a final sprint of a race)
◦ Bruising may also occur along with swelling and pain
over the fractured area.
Common signs of an Avulsion Fracture:
◦ Limp present during gait
◦ Tenderness to palpation
◦ Pain with passive and active muscle stretching
