Dr. Ebraheim’s educational animated video describing the fracture of clavicle collar bone.
The clavicle is a long curved bone that makes up part of the shoulder girdle. The sternal end is rounded. The acromial end is flat. The conoid tubercle is located at the posterior inferior side of the clavicle.
The clavicle is the most common broken bone in the body. The middle third of the clavicle is a common site of fracture because this is the thinnest part of the bone.
Fractures are often caused by
•Falling onto an outstretched shoulder or arm.
•Direct blow to the clavicle.
•Usually associated with sports injuries (bicycling, skiing, etc.)
Patients with clavicle fractures have:
•An obvious deformity (bump) may be present at the site of the fracture.
Treatment is usually non-operative
•Resting with sling or brace
•It is difficult to reduce the fracture with the use of a sling or brace.
Indications for surgery include
•Tenting of the skin
•Significant displacement of the fracture
•Overlap or shortening of fragment by 2 cm or more.
Poor functional outcome
It could decrease shoulder muscle strength and endurance.
•Incision is made
•Fracture is exposed
•Reduction of the fracture
•Plating of the fracture
If the fracture does not heal within 3 months, then it is considered to be in nonunion and the treatment is plate and bone graft.
Clavicular fracture with associated extra-articular glenoid neck fracture
•Treatment is controversial. If the clavicle is displaced, stabilizing both fractures can be achieved by reducing and plating the clavicle only.
Distal third clavicular fracture
•Highest rate of nonunion up to 30%.
•Distal fragment remains in place attached to the ligaments while the medial fragment is free and displaced superiorly.
•The nonunion is minimally symptomatic.
