Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
patients undergoing open reduction internal fixation for a stable ankle fracture will at 2 weeks post surgery have a permanent full below knee cast applied made from a synthetic casting material (Dynacast# Prelude) for 4 weeks and be encouraged to weightbear mobilising using crutches or frame until they are mobilising fully weightbearing.

Comparator / control treatment
patients undergoing open reduction internal fixation for a stable ankle fracture will at 2 weeks post surgery have a permanent full below knee cast applied made from a synthetic casting material (Dynacast# Prelude) for 4 weeks and be non weightbearing mobilising with crutches or a frame.

Outcomes
Primary outcome [1] 279729 0
Olerud & Molander Ankle Score measures:
1. ankle symptoms e.g., pain, swelling
2. functional outcomes e.g., gait supports, stair climbing, jumping
Timepoint [1] 279729 0
2 weeks, 6 weeks, 3 months and 6 months post surgery
Secondary outcome [1] 294322 0
EQ-5D (English version for Australia) is a standardised instrument for use as a measure of health outcome. It is applicable to a wide range of health conditions and treatments. It provides a simple descriptive profile and a single index value for health status.

2 weeks, 6 weeks, 3 months and 6 months post surgery

Eligibility
Key inclusion criteria
Patients with a closed ankle fracture that has a stable syndesmosis and an uninjured posterior syndesmosis that requires open reduction internal fixation .
Minimum age
18 Years
Maximum age
70 Years
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Patients with an open ankle fracture considered unstable for weightbearing at 2 weeks post surgery, e.g. those with unstable syndesmosis requiring a screw across the syndesmosis and those with an injured posterior syndesmosis.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients who have undergone open-reduction internal fixation surgery of their ankle fracture who fit the inclusion criteria will be recruited. These patients will undergo screening for any exclusion criteria. They will then be randomly allocated via sealed opaque envelope to either the early weightbearing group or the traditional six weeks immobilization group.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A 1:1 block randomisation will be used. The assignments are predetermined through a schedule generated using randomly permuted blocks with random block sizes method. The randomisation plan generator available on the randomisation.com website was used.
Masking / blinding

Summary
Brief summary
The aim of this study is to compare the health status and functional outcomes of patients who weightbear at two weeks compared to those who weightbear at six weeks after surgery for an ankle fracture.

Is the health status and functional outcomes for patients who weight bear 2 weeks after surgery for an ankle fracture the same as those who weight bear at 6 weeks after surgery for an ankle fracture?
