Bone Fracture Basics
The average person will experience 2 fractures in their lifetime. A fracture is the medical term for a broken bone. They occur when the physical force exerted on the bone is stronger than the bone itself. Fractures are usually described by the location, how the bones are aligned, whether there are associated complications with blood and/or nerve function, and whether the skin is intact at the injury site.
The most common causes of fractures are:
Trauma - such as a fall, sport activity such as tackling in football, or a motor vehicle accident.
Osteoporosis - which weakens the bone and makes them more likely to break.
Overuse - repetitive motion can fatigue the muscle which places more force on the bone. Stress fractures are common in athletes.
The main categories of fractures are open, closed, displaced, and non-displaced. Closed fractures are those where there is no puncture or open wound to the skin. Open fractures are when the broken bone(s) pierce through the skin. A non-displaced or minimally displaced fracture is when the bone cracks part or all the way through but maintains it proper alignment. A displaced fracture is when the bone snaps in two or more pieces and the ends are not lined up straight.
Common anatomic terms used to describe fractures include:
Proximal – closer to the center of the body
Distal - further from the center
Anterior – toward the front of the body
Posterior – toward the back
Medial - toward the middle of the body
Lateral - to the outer edge of the body
The direction the fracture takes within the bone is described as:
Transverse - the fracture travels across the bone
Oblique - the fracture occurs at an angle
Spiral - the fracture spirals or extends down the length of the bone
Comminuted - the fracture has more than two parts, multiple fragments are present
Symptoms of a fractured bone can include swelling and tenderness around the injury, bruising, and possible deformity – a limb may look “out of place” or a part of the bone may puncture through the skin.
These are the basics of a bone fracture. Now you will understand the fracture “lingo” if you or someone you know sustains a fracture. We are happy to evaluate and treat any bone or joint problems you may have – no referral necessary.
