Design outcomes

Primary

MeasureTime frame
1. Quality of life, assessed at the baseline and at week 6, 12, 24 and 52, using: 1.1 12-item Short Form Health Survey (SF-12) 1.2. EuroQol-5D (EQ-5D) 2. Pain whilst weight-bearing, assessed using the Numeric Pain Rating Scale (NPRS) at the baseline and at week 2, 6, 12, 24 and 52 3. Patient mobilisation, assessed using a timed "up-and-go" test (TUG) at weeks 6 and 12

Secondary

MeasureTime frame
1. Time to bone healing, assessed using: 1.1. Clinical measures: 1.1.1. Painless full weight bearing 1.1.2. Functional IndeX in Trauma (FIX-IT) score 1.2. Radiological measures - Radiographic Union Scale in Tibial fractures (RUST) scale with a CT scan 2. Proportion of participants healed at 3 and 6 months after surgery 3. Rate of surgical re-intervention at 6 months after surgery 4. Incidence of loss of reduction, secondary collapse or further surgical intervention at the 6 month follow up
