Three-Part Question:
In [an adult with an avulsion fracture at the base of the fifth metatarsal] is [immobilisation in a below knee cast better than simple support bandaging] in [controlling symptoms and speeding time to functional recovery]?
Clinical Scenario:
A 38 year old woman presents to the emergency department following an inversion injury of the right ankle. Clinical examination and x-ray confirm that there is an avulsion fracture at the base of the fifth metatarsal. You wonder whether immobilisation in a plaster cast is better than simple support bandaging.

Outcome:
82 papers found of which 77 were irrelevant to the study question and 4 were of insufficient quality for inclusion.

Treatment of fractures of the fifth metatarsal: a prospective study. Wiener BD, Linder JF, Giattini JF. 1997 USA 89 consecutive patients with avulsion fractures of the base of the fifth metatarsal.
Short leg cast vs soft (Jones) dressing
Followed at 2, 4, 8 and 12 weeks.
PRCT Time in support No significant difference No power study. Not blinded. 33% drop out rate
Modified foot score (pain, gait, function, walking distance) No significant difference
Time to full activity Significantly shorter in soft dressing group 33 vs 46 days (p < 0.05)
Time to bony healing No significant difference
Author Commentary:
This is the only trial identified in this area and it has a number of weaknesses. Further well designed and executed studies are warranted.
Bottom Line:
On current evidence simple support bandages are the treatment of choice.
