Official Title: Combined Randomised and Observational Study of Type B Ankle Fracture Treatment
Brief Summary: This study will determine whether operative management confers improved short and long−term outcomes for patients with isolated AO type 44−B1 distal fibula fractures when compared with non−operative management.
Detailed Summary:
Background:
Ankle fractures are common. Recent clinical studies have shown that there is an increasing incidence of ankle fractures. Treatments vary and there is no clear consensus of the ideal approach to type 44−B1 distal fibular fractures. They range from open reduction and internal fixation to restore anatomical alignment to wearing below−knee walking plaster for an average of six weeks.
The argument for surgical fixation is that it addresses minor displacement and possible future displacement therefore potentially preventing future arthritis. On the other hand, there are numerous complications associated with surgery.
The argument for non−operative treatment is that non−union is not a common complication. Therefore surgery can be avoided in the majority of cases avoiding the clinical risks associated with surgery.
Aim:
Primary aim: To compare, ankle function and quality of life in the 12 months following an isolated AO type 44−B1 distal fibula fracture minimal talar shift, between patients treated operatively and non−operatively.
Secondary aims:
- To compare the recovery of ankle function and quality of life between the two study groups from 3 months to 1 year post ankle fracture
- To compare complications between the two groups.
- To conduct a health economic analysis between the two groups as indicated
