What is the mechanism of an olecranon fracture?
What is the mechanism of an olecranon fracture?
Mechanism. Olecranon fractures are common. Typically they are caused by direct blows to the elbow (e.g. motor vehicle accidents), and due to falls when the triceps are contracted. “Side-swipe” injury when driving a motor vehicle with an elbow projecting outside the vehicle resting on an open window’s edge is an example …
What nerve is at risk with an olecranon fracture?
The ulnar nerve is most at risk due to its superficial position on the medial aspect of the elbow. When the injury occurred secondary to a high-energy mechanism, the practitioner should be vigilant to avoid missing injuries that may be unrecognized by the patient due to the distracting nature of the olecranon fracture.
What is a displaced olecranon fracture?
In an olecranon fracture, the bone can crack just slightly or break into many pieces. The broken pieces of bone may line up straight or may be far out of place (displaced fracture). In some cases, the bone breaks in such a way that bone fragments stick out through the skin or a wound penetrates down to the bone.
How common is olecranon fracture?
Olecranon fractures are relatively common injuries, accounting for approximately 10% of upper extremity fractures in adults [26].
What is an olecranon fossa?
The olecranon fossa is located on the posterior surface of the distal humerus, where it receives the proximal ulna during full extension of the arm. The intertubercular groove passes between two tubercles on the humerus.
Does olecranon fracture need surgery?
How is an olecranon fracture treated with surgery? Surgery is usually required for olecranon fractures in which: The bones have moved out of place (displaced fracture) Pieces of bone have punctured the skin (open fracture)
Where is the olecranon process located?
this notch is called the olecranon process; it articulates behind the humerus in the olecranon fossa and may be felt as the point of the elbow.
Is an olecranon fracture painful?
Symptoms of an olecranon fracture may include pain, tenderness, swelling and the inability to straighten the elbow or pain while straightening the elbow. Depending on the degree and type of fracture, treatment may include the use of a sling or surgery to help hold the bones in place while they heal.
What is the difference between olecranon and olecranon process?
The olecranon is the near end of the ulna, the bone in the forearm, and it forms the pointed portion of the elbow. Also known as the olecranon process of the ulna.
What is the olecranon process for?
It forms the most pointed portion of the elbow and is opposite to the cubital fossa or elbow pit. The olecranon serves as a lever for the extensor muscles that straighten the elbow joint.
How does a transolecranon fracture of the elbow occur?
Transolecranon fracture-dislocation of the elbow Anterior elbow dislocations occur most often as a fracture-dislocation in which the distal humerus is driven through the olecranon, thereby causing a complex, comminuted fracture of the proximal ulna.
Can a transolecranon fracture cause anterior Monteggia?
Transolecranon Fracture- Dislocation of the Elbow. This injury is frequently confused with anterior Monteggia lesions by virtue of the readily apparent radiocapitellar dislocation. Stable restoration of the appropriate contour and dimensions of the trochlear notch of the ulna will lead to a good result in most cases.
How many patients have a fracture of the olecranon?
Patients: Three of seventeen patients had simple, oblique fractures of the olecranon, and fourteen had complex, comminuted fractures of the proximal ulna, including fragmentation of the olecranon in seven patients, large coronoid fragments in eight patients, and segmental fractures of the ulna in six patients.
What does a dislocation of the cervical spine mean?
Cervical Spine Fractures and Dislocations A cervical fracture means that a bone is broken in the neck (cervical) region of the spine. A cervical dislocation means that a ligament injury in the neck has occurred, and two (or more) of the adjoining spine bones have become abnormally separated from each other, causing instability.
