What is a capitellum fracture?
Background: Fractures of the capitellum are rare injuries of the elbow usually seen in the adolescents. This fracture is often missed in the emergency room if a proper radiograph is not available. Recent reports have described many modalities of treatment favoring headless screw for fixation.
How is capitellum fracture treated?
A variety of methods of treating capitellum fractures have been described. These include closed reduction, excision, and open reduction with or without internal fixation. Closed reduction of type I capitellar fractures has been reported in a few series [14, 15].
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.
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 long does it take for a capitellum fracture to heal?
Immobilization in a long-arm cast or splint with the elbow flexed to 90 degrees for 4-6 weeks to keep the capitellum reduced to the radial head is recommended.
What is osteochondritis dissecans of the capitellum?
Osteochondritis dissecans (OCD) is a process in which a segment of articular cartilage separates from the subchondral bone. In the human body, OCD lesions are most commonly found in the knee, followed by the ankle and the elbow[1]. OCD of the elbow typically affects the capitellum of the humerus.
What attaches to capitellum?
Anatomy. The radial head articulates with the capitellum of the distal humerus and the ulna (proximal radial ulnar joint). The radial head is a secondary stabilizer of the elbow joint along with the radial and lateral ulnar collateral ligaments and the annular ligament.
How do you pronounce capitellum?
Phonetic spelling of capitellum
- capitel-lum.
- kăp′ĭ-tĕl′əm.
- capitel-lum.
- cap-i-tel-lum. Adrock B.
Why does my capitellum hurt?
Overview of OCD of the Capitellum Osteochondritis dissecans (OCD) is a painful condition in your elbow joint and occurs at the place where the end of one bone meets the end of another bone. It happens when the subchondral bone surrounding the capitellum of your elbow dies due to lack of blood flow.
What is the humeral condyle?
The humeral condyle is the name given to the end of the bone (called the humerus) at the top of the front leg (the forelimb). Together with the radius and ulna (the two bones of the antebrachium or forearm) the humeral condyle makes up the elbow joint.
How do you treat osteochondritis dissecans?
Treatment
- Resting your joint. Avoid activities that stress your joint, such as jumping and running if your knee is affected.
- Physical therapy. Most often, this therapy includes stretching, range-of-motion exercises and strengthening exercises for the muscles that support the involved joint.
How common is osteochondritis dissecans?
Familial osteochondritis dissecans is a rare condition, although the prevalence is unknown. Sporadic osteochondritis dissecans is more common; it is estimated to occur in the knee in 15 to 29 per 100,000 individuals.
What is baumanns angle?
Baumann angle, also known as the humeral-capitellar angle, is used for the evaluation of the displacement of pediatric supracondylar humeral fractures. It is measured on a frontal radiograph, with elbow in extension.
What is gunstock deformity?
Cubitus varus or bow elbow or gunstock deformity is the result of malunion occurring as a complication of supracondylar fracture of the humerus. It occurs in only the extension type of supracondylar fracture of the humerus, causing a reduction or loss of the carrying angle. Various aetiologies have been suggested.
What is a capitulum?
Definition of capitulum 1 : a rounded protuberance of an anatomical part (such as a bone) 2 : a racemose inflorescence (as of the sunflower) with the axis shortened and dilated to form a rounded or flattened cluster of sessile flowers — see inflorescence illustration.
How do you say tubercle bacilli?
Phonetic spelling of tubercle bacillus
- tu-ber-cle bacil-lus.

What is capitellum elbow?
The capitellum is a rounded protuberance on the end of the humerus or upper arm bone. Capitellum fractures are rare injuries of the elbow, usually seen in adolescents, caused by direct trauma or a fall on to the outstretched hand.
How serious is an occult fracture?
An occult fracture is one that does not appear well on an X-ray. A possible occult fracture is a suspected fracture that needs to be confirmed with other imaging tests. Occult fractures can occur because of a fall or other type of sudden (acute) injury.
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.
What is a kneecap dislocation?
Kneecap dislocation occurs when the round-shaped bone covering the knee (patella) moves or slides out of place. The dislocation often occurs toward the outside of the leg. Dislocation – kneecap; Patellar dislocation or instability Kneecap (patella) often occurs after a sudden change in direction when your leg is planted.
What causes swelling of the knee after a dislocation?
Swelling of the knee: This swelling is usually caused by fluid that accumulates in the knee joint due to inflammation after the dislocation, but in some cases, it may be due to blood collecting in the knee joint.
How do medications treat dislocated kneecaps?
Because dislocated kneecaps tend to cause a lot of pain, most people with dislocated kneecaps will need pain medications to control the pain and allow for the kneecap to be put back in place. Pain medications may be given through an IV and may include morphine or fentanyl, among others.
