Healing of a fractured clavicle is often rapid:
- 6 weeks in an adult but with return of function within 3 weeks
- 3 weeks in a child
Traditionally most are treated non-operatively and even in displaced fractures, a high rate of good results with a low non-union rate has been reported (1).
Greenstick injuries require very minimal support.
Operative reduction however, may be indicated in a severely displaced outer one-third fracture. The fracture is held with a pin. A sling should be warn for 6 weeks and active movement encouraged once removed. Untreated, these fractures may cause marked deformity and less commonly, shoulder weakness.
Treatment of clavicle fractures depends on the fracture classification:
- group I (midshaft)
- managed non-operatively whether displaced or non-displaced
- immobilization in a sling or figure-of-eight dressing for one to two weeks or until the major pain subsides (depending on the patient’s comfort level.).
- although figure-of-eight dressing was originally thought to improve alignment, several studies have reported similar union rates and increased satisfaction in patients treated with a simple arm sling (3)
- it is important that:
- active shoulder exercises are performed once the pain subsides
- the sling does not rub against the fracture
- group II (distal)
- non displaced and minimally displaced fractures have low rates of non-union hence the treatment of choice is non-operative, in a simple sling and early range-of-motion exercises as pain allows
- displaced fractures tend to have a high rate of non union and a primary operative intervention may be required (2)
- group III (proximal)
- non displaced fractures - immobilisation in a sling or figure-of-eight dressing is all that is required
- displaced fractures - surgery may be required (3)
Note:
- although non-operative method is preferred in clavicular fractures irrespective of the displacement, some recent studies have suggested that long term results are not as favourable as previously considered
