What is Kocher approach?
What is Kocher approach?
The lateral (Kocher) approach can be used to access the radial head and the tip of the coronoid. In pediatrics the most common use of this approach is open reduction of radial head/neck fractures.
What is radial head excision?
Radial head excision is a surgical procedure that involves the removal of the radial head (the smaller bone of the forearm that makes up the elbow joint) after severe damage following trauma or as a result of degenerative changes associated with arthritis.
What is radial neck fracture?
Radial neck fractures are almost always the result of a fall onto an outstretched hand. Force applied along the radius results in impaction of the radial head against the capitellum. The result is often a radial head or neck fracture. The neck fractures may be complete or incomplete.
What is the annular ligament?
The annular ligament is a strong fibro-osseous circular structure that has attachments to the anterior and posterior margins of the radial notch (lesser sigmoid cavity) of the ulna. The annular ligament forms about four-fifths of a circle.
What is the terrible triad of the elbow?
The terrible triad of the elbow consists of a combination of an elbow dislocation, a radial head fracture, and a coronoid process fracture. This situation almost always renders the elbow unstable, making surgical fixation necessary.
What is Arthrotomy elbow?
An arthrotomy is a surgical procedure that requires surgically opening a joint. During an elbow arthrotomy, a surgical incision is made into the elbow joint, to visualize and diagnose a condition, or to surgically repair problems of the joint.
How soon can I drive after a radial head fracture?
You should not drive whilst in a sling. You can return to work once you are able to do your normal duties. How long will it take to heal? Most fractures heal without any problems in six to twelve weeks.
What happens after radial head replacement surgery?
After surgery, the arm is placed in a soft case for about 2 weeks and then therapy is initiated to regain function. Most patients recover fully with only minor limitation of function, but full recovery can take 3-6 months. The primary long term problem that develops after surgery is stiffness of the elbow joint.
How long does a radial elbow fracture take to heal?
It usually takes approximately 6 weeks for the fracture to fully heal. During this time, do not stress the joint with heavy lifting or heavy weight-bearing. It will not cause any further damage if you continue to use your elbow normally for everyday activities.
What is a radial neck fracture of elbow?
Radial neck fractures are uncommon and account for 8% of all elbow fractures in children. The most common mechanism is a fall onto the outstretched arm with a valgus stress at the elbow. They can also occur as a result of a posterior dislocation or reduction of the elbow joint.
What nerve Innervates the main elbow flexors?
The muscle is innervated by the musculocutaneous nerve. The lateral portion of the muscle covers the radial nerve as it spirals around the distal humerus.
What are the primary motions of the elbow?
The elbow joint is a synovial hinge-type joint that serves as the articulation between the humerus, radius, and ulna (see Fig. 65-3). The joint’s primary function is to position the wrist to optimize hand function. The joint allows flexion and extension at the elbow as well as pronation and supination of the forearm.
Why was Kocher approach to the elbow so important?
The stakes were higher this time around to be sure, but the music more than delivers, bolstered by the kind of growth that can only come from the trial-by-fire the band experienced on their meteoric rise. An error occurred while retrieving sharing information.
When to use Kocher approach to radial head?
The lateral (Kocher) approach can be used to access the radial head and the tip of the coronoid. In pediatrics the most common use of this approach is open reduction of radial head/neck fractures. 2. Skin incision Either a posterior skin incision with a lateral skin flap or a lateral skin incision can be used.
How is the lateral Kocher / Kaplan approach used?
The lateral Kocher/Kaplan approach can be used to access the radial head and the tip of the coronoid. 2. Skin incision Either a posterior skin incision with a lateral skin flap or a lateral skin incision can be used. For a lateral skin incision, place the elbow at 90 degrees and try to pinch the lateral condyle (easier in thin patients).
Where is the Kocher interval in the forearm?
The Kocher interval The Kocher interval is between the extensor carpi ulnaris and the anconeus. 6. Avoiding damage to nerves Fully pronate the forearm to protect the posterior interosseous nerve by moving it away from the operative field.
