Plain English summary of protocol
Background and study aims
The tibia (shinbone or shankbone) is the most commonly broken major bone in the leg. Injuries usually require hospital admission, frequently require surgery and result in prolonged periods (months) away from work and social activities. The treatment of displaced, extra-articular fractures of the distal tibia (lower third) remains controversial. These injuries are difficult to manage due to the limited soft tissue cover, poor vascularity of the area and proximity of the fracture to the ankle joint. Infections, non-union and malunion are well-recognised complications. The aim of this study is to find out whether there is a clinical and cost-effectiveness difference between two techniques for the operative fixation of fractures of the distal tibia: locking-plate fixation and intramedullary nail fixation.
Who can participate?
All patients aged 16 years or over presenting at the trial centres with an isolated, acute fracture of the distal tibia are potentially eligible to take part in the trial.
What does the study involve?
Participants will be randomly allocated to either intramedullary nailing or locking-plate fixation. Both of these operations are widely used within the NHS and all of the surgeons in the chosen centres will be familiar with both techniques. A research associate will perform a clinical assessment and make a record of any early complications at 6 weeks after the operation and an x-ray will be taken. A further clinical assessment and x-ray will also be taken at 12 months after the operation to detect late complications. Participants will complete questionnaires at 3 months, 6 months and 12 months after the operation.
What are the possible benefits and risks of participating?
The patient may benefit from internal fixation of the fracture. The risks associated with this study are predominantly the risks associated with the surgery: infection, bleeding and damage to the adjacent structures such as nerves, blood vessels and tendons. Participants in both groups will undergo surgery and will potentially be at risk from any/all of these complications. There is no data to suggest that the risk is greater in one group or another. We believe that the overall risk profile is similar for the two interventions but assessment of the number of complications in each group is a secondary objective of this trial.
Where is the study run from?
The University of Warwick in collaboration with University Hospitals Coventry and Warwickshire NHS Trust (UK)

| Scientific title | UK FixDT - a randomised controlled trial for patients with a displaced fracture of the distal tibia, is there a clinical and cost-effectiveness difference between 'locking' plate fixation and intramedullary nail fixation |
| Study acronym | UK FixDT |
| Study objectives | Null hypothesis: There is no difference in the Disability Rating Index (DRI) at 6 months after injury between adults with a displaced fracture of the distal tibia treated with 'locking'-plate fixation versus intramedullary nail fixation. |
| Ethics approval(s) | NRES Committee West Midlands - Coventry & Warwickshire, 06/11/2012, REC ref: 12/WM/0340 |
| Health condition(s) or problem(s) studied | Distal Tibia Fractures / Injuries & Accidents |
| Intervention | Comparing two techniques for the operative fixation of fractures of the distal tibia. Intramedullary nailing The intramedullary nail is inserted at the proximal end of the tibia and passed down the centre of the bone in order to hold the fracture in the correct (anatomical) position. The reduction technique, the surgical approach, the type and size of the nail, the configuration of the proximal and distal inter-locking screws and any supplementary device or technique will be left entirely to the discretion of the surgeon as per standard clinical practice. 'Locking' plate fixation The 'locking' plate is inserted at the distal end of the tibia and passed under the skin on the surface of the bone. Again, the details of the reduction technique, the surgical approach, the type and position of the plate, the number and configuration of fixed-angle screws and any supplementary device or technique will be left to the discretion of the surgeon. The only stipulation is that fixed-angle screws must be used in at least some of the distal screw holes - this is standard practice with all distal tibia 'locking' plates. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure | To quantify and draw inferences on observed differences in the Disability Rating Index between the trial treatment groups at 6 months after injury |
| Secondary outcome measures | 1. To quantify and draw inferences on observed differences early functional status at 3 months and later functional status at 12 months 2.To quantify and draw inferences on observed differences in the radiological outcomes: non-union, mal-alignment and shortening 3. To identify any differences in health-related quality of life between the trial treatment groups in the first year after the injury. EQ-5D; The EQ-5D is a validated, generic health-related quality of life measure consisting of 5 dimensions each with a 3-level answer possibility. Each combination of answers can be converted into a health utility score. It has good test-retest reliability, is simple for patients to use, and gives a single preference-based index value for health status that can be used for broader cost-effectiveness comparative purposes. 4. To determine the complication rate of intramedullary nail fixation versus 'locking'-plate fixation in the first year after the injury. all complications will be recorded, including malunion, delayed/non-union, infection, wound complications, vascular and neurological injury and venous thrombo-embolism. A record will also be kept of any other surgery required in relation to the index fracture, including removal of any metalwork. 5. To investigate, using appropriate statistical and economic analytical methods, the resource use, costs and comparative cost effectiveness of intramedullary nail fixation versus 'locking'-plate fixation Olerud and Molander (OMAS) is a self-administered patient questionnaire. It is a good outcome tool for assessing symptoms after an ankle fracture. The score is based on nine different items: pain, stiffness, swelling, stair climbing, running, jumping, squatting, supports and work/activities of daily living. The scoring system correlates well with parameters considered to summarise the results after this type of injury and is therefore recommended for use in scientific investigations. |
