Plain English Summary

Background and study aims
Broken ankles in children often involve the area from which the bone grows – the growth plate. Following growth plate injuries, the growth of the main shin bone in the lower leg (the tibia) can be altered permanently, which can cause the bone to not grow at all, or to grow wonky. Altered growth may affect how well the leg works. The younger the child at the time of injury (i.e. the more they have to grow), the worse the problem may become once the child has fully grown. There are different ways to treat this injury, but it is currently unclear whether one type of treatment is better than another. Some doctors believe that children with growth plate injuries need surgery to reset their bones to ensure that the growth plate is restored to its original position. They believe that this will lower the chance of abnormal growth. However, other doctors believe that attempting to reset the bones to restore the growth plate with surgery could bring about further damage. These doctors recommend the bones be treated in a plaster cast, without surgery to reset the bones. This study aims to look at whether when children aged between 8 and 15 years old break their ankles, surgery to reset the bones leads to better function than letting the bones heal using a plaster cast without resetting the bones. At the end of the study, the information will be combined about all the children that took part. This will help everyone to understand which treatment is best. To make sure people learn about the best treatment, the doctors who help with this study will talk to other doctors and other people in the NHS who write national guidelines. Patient co-investigators will help deliver the message to families and will be invited to share their experience of the study with medical professionals.

Who can participate?
Children aged between 8 and 15 years old who have a fracture through the growth plate at the bottom of the shin bone, where the bone ends have moved apart from each other.

What does the study involve?
In the study, half the children and young people will have their broken bones treated with surgery, whilst the other half will have a plaster cast with no surgery. Those who agree to join the study, with the support of their families, will be split fairly into two groups, using a research process called ‘randomisation’. Children will be assigned one of two treatments:
1. Surgical reduction – the children in this group will have an anaesthetic or be sedated so their bones can be reset in theatre, and a plaster cast put on their leg. Sometimes, if the doctor thinks it necessary, wires, screws or a plate and screws will be inserted to hold the broken bones in position.
2. Conservative treatment – the children in this group will not have the bones reset in position, they will receive a plaster cast for support to allow the bones to heal naturally. The plaster casts will stay on for around 4-6 weeks for both treatments.

All children will be followed up for two years to keep track of their function, and the length and appearance of the leg. They will be asked about pain, whether they needed any more surgery, school attendance, complications, the number of hospital visits, their quality of life and satisfaction with treatment. Follow-up will occur at 6 weeks, 3, 6, 12 & 24 months. Participant follow-up will be organised by the University of Oxford – either electronically by email or text message or by telephone

What are the possible benefits and risks of participating?
Each of the two routinely used treatments has potential advantages and disadvantages.

1. Resting the leg in a plaster cast for up to 6 weeks, to allow it to heal by itself. The benefit is avoiding surgery. However, the growth plate is not in the perfect position, which may mean that it doesn’t grow normally. This might cause a difference in the shape of the leg (i.e. the ankle could grow wonky) or the injured leg could become shorter than the uninjured leg. This may need future surgery to correct these problems and could cause pain and arthritis in the future.

2. Surgery to fix the bone, usually with screws and a plaster cast for up to 6 weeks. The benefit is that surgery puts the growth plate in the natural position, which many surgeons believe may help the leg grow normally. However, there are risks of surgery, such as the risk of an anaesthetic, infection, wound problems, pain or stiffness, injury to nerves supplying the foot and problems related to the metal implants. There is also still a chance that the leg doesn’t grow normally, and often a need for a second operation to remove any metal implants.

Where is the study run from?
Alder Hey Children’s NHS Foundation Trust is the sponsor for the study and has overall responsibility for the management of it. This study will be overseen by Oxford Clinical Trials Research Unit (OCTRU) with the day-to-day running of the study being completed by Oxford Trauma and Emergency Care at the University of Oxford.

The research team has a lot of experience in caring for children and young people with injuries and is active in health research. Parents and children have been involved in the development of this study, and are involved in the management.

When is the study starting and how long is it expected to run for?
September 2021 to May 2027

Who is funding the study?
The National Institute for Health and Care Research (NIHR) Health Technology Assessment (HTA) Programme (Reference NIHR132675)

Study acronymODD SOCKS
Study hypothesisThis pragmatic randomised controlled trial aims to evaluate the clinical and cost-effectiveness of surgical reduction, compared to conservative treatment, for the management of displaced Salter Harris-II fractures of the distal tibial physis in children.
Ethics approval(s)

Approved 18/01/2024, East Midlands - Nottingham 1 Research Ethics Committee (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 (0)207 104 8115, (0)207 104 8271, (0)207 104 8089; Nottingham1.rec@hra.nhs.uk), ref: 24/EM/0006

ConditionChildhood displaced Salter Harris-II fractures of the distal tibial physis
InterventionThe proposed project is a two-phased study. Phase 1 (internal pilot) will confirm the expected rate of recruitment and pilot data collection procedures in a large-scale multi-centre RCT. Phase 2 is the expansion of the internal pilot into the full definitive trial (main RCT). Phase 2 is the expansion of the pilot into the full definitive trial. A full trial report for the funder and peer-reviewed publications of the main results will be generated after the completion of this phase.

All children aged 8-15 years inclusive presenting to the trial centres with a displaced fracture of the distal tibia involving the physis and metaphysis (i.e. Salter-Harris II) are potentially eligible to take part. Upon presentation, children will receive analgesia and their ankles will be assessed to ensure that the fracture does not require an emergency realignment (i.e. compromising the blood or nerve supply to the foot, or causing potential damage to the skin and other soft tissue structures). Once any emergency realignment is either performed or confirmed to not be required, temporary immobilisation of the limb for comfort will be applied as per the usual practice of the treating centre. In many hospitals the decision related to definitive treatment is taken in the emergency department by the on-call orthopaedic surgical teams; in others the child may be discharged to an early appointment in the fracture clinic. Owing to the nature of the condition and treatment pathways, the study will be introduced to the patient at the point where definitive care is planned.

After informed consent/assent has been obtained, baseline demographic and injury data, physical function using the PROMIS Mobility CAT, pain intensity using the Wong-Baker FACES Pain Scale and health-related quality of life using the EQ-5D-Y will be collected.

The children will be split into two groups, using a research process called ‘randomisation’ using a computer randomisation service to fairly allocate treatments:

1. Surgical Reduction- the children in this group will have an anaesthetic or be sedated so their bones can be reset in theatre, and a plaster cast put on their leg. Sometimes, if the doctor thinks it necessary, a small cut will be made and wires, screws or a plate and screws will be inserted to hold the broken bones in position.

2. CONSERVATIVE TREATMENT group – the children in this group will not have the bones reset in position, they will receive a plaster cast for support and to allow the bones to heal.

After treatment, the parents and/or participants will be asked to complete further questionnaires at 6 weeks, 3 months, 6 months, 12 months and 24 months after randomisation.

Data will be collected primarily electronically (with a telephone interview where required) with email and/or text message prompts.
Participants will usually attend an orthopaedic follow-up clinic regularly, as part of standard care and until they are approximately 16 years old, or at least for 2 years after the initial surgery to monitor for signs of complications. In both groups, children will have up to two additional X-rays to what they would have if they were not taking part in this study.
Intervention typeProcedure/Surgery
Primary outcome measureTo determine whether children treated with surgical correction have improved function compared with children treated with conservative care measured using the PROMIS Mobility questionnaire, at 24 months post-randomisation
Secondary outcome measuresThe following secondary outcome measures will be assessed during the first 2-years post-randomisation between surgical reduction and conservative treatment:
1. Function measured using the PROMIS-Mobility Score at 6 weeks, 3, 6 and 12 months post-randomisation
2. Pain scores measured using the Wong-Baker faces pain rating scale at 6 weeks, 3, 6, 12 and 24 months post-randomisation
3. Quality of life measured using EQ-5D-Y at 6 weeks, 3, 6, 12 and 24 months post-randomisation
4. Complication rate measured using data collected in medical records at 6/8 weeks, 12 and 24 months post-randomisation
5. Satisfaction with cosmetic appearance of the leg measured using the Visual Analogue Scale (VAS) of cosmesis at 3, 12 and 24 months post-randomisation
6. Satisfaction with the treatment received measured using a Likert Scale at 3, 12 and 24 months post-randomisation
7. Child educational participation recording educational absences measured using a parent-reported questionnaire at 6 weeks, 3, 6, 12 and 24 months post-randomisation
8. Leg Length Measurement measured using the ‘Tape Measurement Method’ by a clinician at 12 and 24 months
9. Angular deformity and PPC (growth arrest) measured using radiographic images 24 months post-randomisation
10. Resource use measured using a bespoke electronic resource use questionnaire, and parental absence from work at 6 weeks, 3, 6, 12 and 24 months post-randomisation
