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 the classification of radial head fractures?
Radial head fractures are classified according to the degree of displacement and intra-articular involvement, using the Mason classification: Mason Type 1 – Non-displaced or minimally displaced fracture (<2mm). Mason Type 2 – Partial articular fracture with displacement >2mm or angulation.
Which of the following is the most common mechanism of injury for a radial head fracture?
Radial head fractures are the most common elbow fracture in adults. The most common mechanism of injury is falling onto an outstretched hand with the forearm pronated. These fractures can also result from falling directly onto the elbow.
What is the annular ligament?
The annular ligament is a complex structure formed from the capsule, lateral collateral ligamentous complex, and supinator muscle that act in unison to stabilize the proximal radioulnar joint. Its posterior attachment to the ulna can be fenestrated normally.
How long immobilize radial head fracture?
If you have a small fracture and your bones did not move around much, you will likely wear a splint or sling that supports your arm, elbow, and forearm. You will probably need to wear this for at least 2 to 3 weeks. If your break is more severe, you may need to see a bone doctor (orthopedic surgeon).
What is an impacted radial head fracture?
Most elbow fractures, including radial head fractures, happen when you fall onto your outstretched hand. As you try to catch yourself, the impact goes up your bones, from your wrist to your forearm to the elbow and up the humerus to your shoulder. At some point, the bones may not resist the weight and break.
What is radial head arthroplasty?
Radial head arthroplasty is used in cases of complex radial head fractures. This includes fractures with substantial comminution or bone loss prohibiting ORIF. Concurrent instability also favors using an implant over head excision.
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 Anconeus muscle?
The anconeus muscle is a triangular-shaped muscle originating posterior to the lateral epicondyle of the humerus and then fanning out broadly for an insertion base on the proximal part of the posterolateral side of the ulna.3,11. From: Morrey’s the Elbow and its Disorders (Fifth Edition), 2018.
What is a radial fracture elbow?
Fractures of the radius often occur in the part of the bone near the elbow, called the radial head. Radial head fractures are common injuries, occurring in about 20% of all acute elbow injuries. Many elbow dislocations also involve fractures of the radial head.
