he hidden danger of elbow fractures: Why are olecranon fractures so common?
Elbow fractures are common sports injuries, especially olecranon fractures, which are damage to the fragile part of the elbow bone, usually after a fall or external impact. According to preliminary data, the incidence of this fracture is closely related to accidents in daily life, making many potential victims unable to anticipate the consequences of this injury.
Signs of damage
People who experience an olecranon fracture will experience severe elbow pain following a direct blow or fall. The injured area will swell and you will often be unable to straighten your elbow because of the nerves in the elbow. You may experience numbness or tingling in the fourth and fifth fingers of your hand.
Damage Mechanics
According to the data, this type of fracture is generally caused by direct impact or fall. For example, "side-impact" injuries, where the elbow is stuck out of the window while driving, or falling with the elbow landing directly on the ground, are common injury scenarios.
Diagnostic Methods
When diagnosing an olecranon fracture, your doctor will do a careful skin examination to make sure there is no open fracture. A neurologic examination is then done to ensure that the nerves in the arm are functioning normally. Frontal and lateral x-rays are usually taken to assess the pattern and displacement of the fracture.
Classification of fractures
There are many ways to classify olecranon fractures, and there is no unified standard, but the most widely used classifications include:
- Mayo classification: There are three types, classified according to stability, displacement and fragmentation.
- AO classification: Groups all fractures of the proximal ulna and radius into one, classified into three patterns.
- Colton classification: Classifies fractures into five types, including different parameters such as non-displaced and fragment fractures.
- Schatzker classification: It is subdivided according to the shape and state of the fracture.
Treatment methods
Depending on the diagnosis, treatment methods are mainly divided into the following two categories:
Non-displaced fractures
Minor nondisplaced fractures can usually be immobilized with a posterior fixator, holding the elbow in 45° to 90° of flexion for three weeks, followed by limited-range flexion exercises.
Displaced fractures
Most olecranon fractures are displaced and usually require surgical treatment, which may include:
- Tension band fixation: The most common internal fixation method, using K-wires to fix non-fragmented fractures.
- Intramedullary fixation and plate fixation: for simple transverse or oblique fractures.
- Resection and triceps advancement: commonly used in extremely comminuted fractures or other special situations.
Olecranon fractures are relatively uncommon in children, accounting for only 5% to 7% of all elbow fractures. In adults, this type of fracture is extremely common, partly because the elbow is located in an exposed position and is easily affected by external impacts.
