Fracture of the capitellum is an intra-articular fracture of the elbow, analogous to the Hoffa fracture of the knee. It is a rare fracture which represents an injury to the lateral column of the distal humerus. The mechanism of injury is usually an axial loading through the radial head [3].
What is a capitellum fracture?
Capitellum Fractures are traumatic intra-articular elbow injuries involving the distal humerus at the capitellum.
What is the humeral capitellum?
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.
What is the capitellum of the elbow?
The capitellum is the first ossification center in the elbow to ossify if development of the joint is normal. This center should have become apparent by two years of age.
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 the Trochlea in the elbow?
The humeral trochlea is an important articular surface of the elbow that is injured frequently in falls onto the upper extremity. … The trochlea forms the articular surface of the medial column of the elbow and is responsible for allowing ulnohumeral flexion and extension.
What is a Supracondylar?
Your child’s humerus is fractured (broken) near the elbow area, just above the joint. This is called a supracondylar (supra CON dy ler) humerus fracture. It is the most common type of elbow fracture and happens most often to children younger than 8 years old.
What is Panner disease?
Panner’s disease causes elbow pain around the outside part of the elbow. The pain usually gets worse with activity, such as throwing a ball, and becomes better with rest. The elbow also may be stiff, swollen, and hurt to touch.
What is a medial epicondyle fracture?
A medial epicondyle fracture is an avulsion injury of the attachment of the common flexors of the forearm. The injury is usually extra-articular but can be sometimes associated with an elbow dislocation.
Is the Capitellum cartilage?
There are two cartilage-covered parts of the end on the humerus: The trochlea on the inside of the elbow. The capitellum on the outside of the elbow.
What side is the ulna on?
The forearm consists of two bones, the radius and the ulna, with the ulna is located on the pinky side and the radius on your thumb side.
Is the Trochlea part of the humerus?
The medial portion of the articular surface of distal humerus is named the trochlea, and presents a deep depression between two well-marked borders; it is convex from before backward, concave from side to side, and occupies the anterior, lower, and posterior parts of the extremity.
What is osteochondral defect in elbow?
Osteochondral lesions of the elbow are injuries that disrupt the cartilage and subjacent bone, and they most commonly involve the capitellum. The staging, prognosis, and treatment of osteochondral lesions in the elbow are based on a combination of radiographic, magnetic resonance imaging, and arthroscopic findings.
How long does it take to recover from OCD elbow surgery?
After the surgery, you will be advised not to return to any overhead throwing sports or activities until the injury is completely healed, even if motion is restored and pain is absent. It may take between 4 months to 2 years to fully recover from OCD of the capitellum.
What is OCD in the elbow?
Osteochondritis dissecans (OCD) is a disorder of articular cartilage and subchondral bone. In the elbow, an OCD is localized most commonly at the humeral capitellum. Teenagers engaged in sports that involve repetitive stress on the elbow are at risk.
How long is recovery from terrible triad elbow?
regained full motion and your bones and ligaments have healed. Usually starts around 6-12 weeks after injury.
How is a dislocated elbow treated?
Simple elbow dislocations are treated by keeping the elbow immobile in a splint or sling for 1 to 3 weeks, followed by early motion exercises. If the elbow is kept immobile for a long time, the ability to move the elbow fully (range of motion) may be affected.
How do you treat nursemaid’s elbow?
Nursemaid’s elbow is treated with a simple manipulation of the elbow in our office, usually with the child sitting on a parent’s lap while the doctor or Physician Assistant quickly but gently moves the joint back into place. A small pop may be heard when the joint slips into place.
What is the normal end ROM of elbow flexion?
between 130° and 154° The elbow joint allows us to perform flexion–extension and pronation–supination movement. According to the literature, values for flexion lie between 130° and 154° and extension between –6° and 11°. Pronation varied from 75° to 85° and supination from 80° to 104°.
Which bone is the shortest in the forearm?
Compared to the ulna, the radius is slightly shorter, thinner, and located on the medial side of the forearm. The radius is narrowest at the elbow and widens as it extends towards the wrist.
How many articulations does the elbow joint have?
3 articulations Overview. The human elbow is the summation of 3 articulations.
Is supracondylar fracture an emergency?
Displaced supracondylar fractures have been traditionally treated as surgical emergencies due to the risk of neurovascular complications or the belief that open reduction instead of closed reduction will be needed if surgery is delayed.
Do supracondylar fractures require surgery?
Surgery isn’t always required. Sometimes a hard cast may be enough to promote healing. Complications of supracondylar fracture can include injury to nerves and blood vessels, or crooked healing (malunion).
Can a broken humerus heal without surgery?
Most fractures of the proximal humerus can be treated without surgery if the bone fragments are not shifted out of position (displaced). If the fragments are shifted out of position, surgery is often performed to allow earlier mobility.
Is nursemaid’s elbow common?
Nursemaid’s elbow is a common injury of early childhood. It is sometimes referred to as pulled elbow because it occurs when a child’s elbow is pulled and partially dislocates.
Can you get a stress fracture in the elbow?
Unlike in an accident, a stress fracture happens gradually. It can take months or years for the bone to weaken and for the stress fracture to occur. A stress fracture can happen anywhere in the body, but the most common places are in the bones located in the lower legs and arms – including the elbow joint.
What are the signs and symptoms of osteochondritis dissecans?
What are the symptoms of osteochondritis dissecans?
- Pain and swelling in the affected joint that worsens with activity.
- Locking and “catching” of the affected joint.
- A “giving way” sensation in the affected area.
- Changes in the range of motion in the joint.
Does medial epicondylitis heal?
Most cases will improve with OTC medication and home remedies. If your symptoms don’t improve, your doctor may suggest surgery as a last resort. This surgery is known as an open medial epicondylar release.
How do you tell if you fracture your medial epicondyle?
Features of a medial epicondylar avulsion injury include 1 – 3:
- soft tissue swelling. this may be the only sign of an undisplaced injury. …
- widening of the growth plate (comparison to the contralateral side may be useful)
- obvious displacement of the apophysis.
- fracture through the adjacent humeral metaphysis.
How long does medial epicondyle fracture take to heal?
The most common timeline is to be in a long arm cast for two to four weeks.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
