What is comminuted clavicle fracture?

What is comminuted clavicle fracture?

Clavicle fractures vary. The bone can crack just slightly or break into many pieces (comminuted fracture). The broken pieces of bone may line up straight or may be far out of place (displaced fracture). This illustration shows a clavicle fracture close to where the bone attaches to the scapula (shoulder blade).

Does a displaced clavicle fracture need surgery?

Clavicle fractures that are displaced or shifted significantly may require surgery. Additionally, clavicle fractures with interposed loose “butterfly” fragments or a “kickstand” piece may require surgery.

How do you treat a distal clavicle fracture?

Conservative treatment of distal clavicle fractures includes immobilization with an arm sling or a figure-of-eight bandage. Recently, arm slings have become more commonly used because of patient comfort.

What is a displaced clavicle fracture?

A displaced collarbone fracture happens when the ends of the broken bones don’t line up. Dislocated shoulder occurs when the upper arm bone (humerus) pops out of the shoulder blade socket. A partial dislocation means part of the humerus remains in the socket.

How is a displaced clavicle fracture treated?

Treatment with an arm sling is preferred over a figure-of-eight dressing for acute midshaft clavicle fractures because it is better tolerated and leads to similar outcomes. Displaced midshaft clavicle fractures may be managed nonoperatively, but plate fixation should be considered.

How long does it take for a clavicle fracture to heal?

Clavicle fractures in children (younger than 8 years old) may heal in four or five weeks, and clavicle fractures in adolescents may take six to eight weeks. However, fractures in adults or teenagers who have stopped growing take 10 to 12 weeks to heal and may take longer.

What is the distal end of clavicle called?

acromial end
Extremities. The orientation of the clavicle can be distinguished by its ends: a broad, flat acromial end (referred to as the lateral third); and a round pyramidal-like sternal end (referred to as the medial two-thirds).

Which structures are at risk with a displaced fractured clavicle?

Additionally, the brachial plexus also passes behind the clavicle posterolateral to the subclavian vessels and is at risk with displaced fractures of the middle clavicle.

What type of fracture is a comminuted fracture?

A comminuted fracture is when the bone breaks into several pieces. A transverse fracture is when the fracture line is perpendicular to the shaft (long part) of the bone. An oblique fracture is when the break is on an angle through the bone. A pathologic fracture is caused by a disease that weakens the bone.

What is a distal clavicle fracture?

Summary. Distal clavicle fractures are traumatic injuries usually caused by direct trauma to the shoulder from a fall in adults.

Is a comminuted fracture considered displaced?

Displaced and non-displaced fractures refer to the alignment of the fractured bone. In a displaced fracture, the bone snaps into two or more parts and moves so that the two ends are not lined up straight. If the bone is in many pieces, it is called a comminuted fracture.

What is the lateral end of a clavicle fracture?

Distal Clavicle Fractures. The lateral fracture fragment is held in place by the coracoclavicular ligaments, but pulled downward and medially by the weight of the arm and by the pectoralis and latissimus dorsi muscles, while the medial fragment is pulled superiorly by the trapezius and sternocleidomastoid muscles.

What is the distal end of a bone?

Distal: The more (or most) distant of two (or more) things. For example, the distal end of the femur (the thigh bone) is the end down by the knee; the end more distant from the torso. The distal bile duct is the far end of the cystic duct, the end away from the gallbladder.

Where is the distal clavicle located?

A distal clavicle fracture is a complete or incomplete break (fracture) in the outer third of the collarbone (clavicle) near where it attaches to the shoulder blade (acromion).
