What is capitellum?
The capitellum, also referred to as the capitulum, is the lateral part of the humeral condyle that articulates with the radial head.
What is a olecranon fracture?
An olecranon fracture is a break in the “pointy bone” of your elbow that sticks out when you bend your arm, which is actually the end of the ulna.
Where is the Capitellum bone?
In human anatomy of the arm, the capitulum of the humerus is a smooth, rounded eminence on the lateral portion of the distal articular surface of the humerus. It articulates with the cupshaped depression on the head of the radius, and is limited to the front and lower part of the bone.
How do you treat a olecranon fracture?
Some olecranon fractures can be treated by being casted or placed in a splint to hold the elbow in place while the bone heals. Surgery may be indicated if the elbow is displaced or if the fracture is open. Displaced fractures are treated operatively by internal fixation using wires, screws or plates.
Where is the olecranon process located?
Location. The olecranon has a beak-like structure and is bent forwards into the olecranon fossa of the humerus during extension of the elbow. It is present over the posterior surface of the elbow and forms the palpable ‘point’ of the elbow during its full extension.
How serious is a radial head fracture?
The prognosis for simple radial head fractures is generally excellent. The more comminuted radial head fractures and those that involve other injuries to the ligaments of the wrist and elbow are more likely to result in longer healing time and may require more extensive physical therapy to regain elbow motion.
How long does a radial head replacement last?
At a mean of approximately 10 years, a bipolar radial head prosthesis with a smooth stem demonstrated excellent long- term implant survival and effective restoration of elbow stability and functionality after comminuted radial head fractures.
What kind of surgery is needed for a capitellum fracture?
Capitellum Fractures are traumatic intra-articular elbow injuries involving the distal humerus at the capitellum. Diagnosis is made using plain radiographs of the elbow. Treatment may be nonoperative for nondisplaced fractures but any displacement generally requires anatomic open reduction and internal fixation.
How does a capitellum fracture affect the elbow?
direct, axial compression with the elbow in a semi-flexed position creates shear forces. pathoanatomy radiocapitellar joint is an important static stabilizer of the elbow. capitellar fracture can cause potential block to motion and instability due to loss of the radiocapitellar articulation.
How does an orthopedic surgeon repair articular cartilage?
Many procedures to restore articular cartilage are done arthroscopically. During arthroscopy, your surgeon makes three small, puncture incisions around your joint using an arthroscope. Some procedures require the surgeon to have more direct access to the affected area.
