Objectives | To investigate the clinical and cost-effectiveness of internal plate fixation versus external fine wire fixation for the management of type C pilon fractures of the distal tibia. | To establish whether it is feasible to deliver a trial comparing surgical fixation to initial non-surgical management for patients with a stable thoracolumbar fracture without spinal cord injury. |
Design | Parallel randomised controlled trial. A 12-month internal pilot with associated qualitative study to assess recruitment and provide guidance on optimising trial processes. | A feasibility study consisting of three elements: a randomised external feasibility study, a national survey of surgeons and a qualitative study. |
Trial interventions | Arm 1: Internal fixation: ‘Locking’ plate fixation with screws. Arm 2: External frame fixation: limited open reduction and articular fixation using screws and fine wire fixator. | Arm 1: Surgical fixation. Either open spinal surgery or minimally invasive surgery as per current UK surgical treatment. Arm 2: Non-surgical management. Mobilisation in a brace or mobilisation without a brace. |
Primary outcome | Disability Rating Index at 12 months post-randomisation. | Recruitment rate, defined as the proportion of eligible participants who are randomised. |
Trial status and registration | Ongoing (ISRCTN98152560) | Completed (ISRCTN12094890) |
