Study information
Scientific title
Influence of ankle skin perfusion on fracture treatment outcomes in the elderly: a randomised controlled trial comparing total contact cast with open reduction and internal fixation, the effect on cutaneous blood supply and relationship to skin complications
Acronym
AS04 Ankle study
Study hypothesis
Current proven treatment methods for ankle fracture in the older patient can be associated with complications due to poor skin, bone or healing. A casting technique, proven successful in treating critical skin breakdown in diabetic patients, has in a local audit shown potential as an alternative treatment in the elderly ankle fracture patient. This study will address the questions:
1. What contribution does the adequacy of the skin blood supply make to healing
2. How does a new cast treatment compare with the 'traditional' open surgical approach with regard to healing and function
