Condition
Closed fractures of the ankle
Intervention
All patients who meet the inclusion criteria will be identified on admission and given the choice of entering the trial at which point they will sign a consent form. Patients can exit the trial at any point. Two cohorts of patients will exist, those for traditional fixation with a neutralisation plate, screws and medial malleolar screws, and there will also be those who have the biodegradable implants used.
Randomisation will be done using block randomisation. Four treatments, two of each kind, will be allocated to the block. All combinations for the order of treatment will be included. Consequently there will be six blocks. A random number generator will then be use to allocated a block of treatment to each sequence of four successive patients.
