Plain English summary of protocol
Background and study aims
Lateral Compression (type 1) fractures of the pelvis make up around 60% of pelvic fractures. A proportion of these are termed as unstable, meaning that there is a greater risk of the bone fragments displacing over time. This may lead to difficulties with mobilising and prolonged periods of pain. Therefore it may be appropriate to stabilise these fractures through surgery. However, surgery also has some significant risks such as infection, nerve damage etc. Currently there is no evidence to support either surgical or non-surgical management of these fractures. This study aims to test the feasibility of carrying out a future large scale study to inform the most appropriate management of these injuries.
Who can participate?
Patients aged 16 and older with an LC1 fracture with complete sacral fracture
What does the study involve?
Participants are randomly allocated to either follow a surgical or a non-surgical treatment pathway. The exact details of these two pathways are left to the discretion of each patient’s treating pelvic specialist. Participants are assessed at regular intervals to complete questionnaires relating to their symptoms and daily activities as well as a physical assessment of their walking. A small proportion of participants are asked to take part in an interview to examine their acceptance of the treatments, study design and assessments used. The number of patients recruited to the study and the completeness of the data are also assessed.
What are the possible benefits and risks of participating?
Participation in this study will help us to design a future study to inform the most appropriate treatment of patients with an unstable LC1 fracture in the future. It is hoped that the outcomes of this future study will provide clearer information on whether surgical treatment of these injuries is most appropriate.

| Ethics approval(s) | South West – Central Bristol Research Ethics Committee, 02/07/2018, ref: 18/SW/0135 |
| Health condition(s) or problem(s) studied | Pelvis fracture |
| Intervention | Patients with a pelvic fracture will be referred to one of the hospitals specialising in the treatment of these injuries. Those identified as having sustained an unstable LC1 fracture by their treating pelvic specialist, and meeting the criteria for inclusion in the study, will be approached to see if they would be willing to take part in the study. Patients will be asked to complete a written consent form to indicate their agreement to take part and will be asked to complete a series of short questionnaires relating to their daily activities and symptoms both prior to and since their injury. They will then be randomised by computer to follow either a non-surgical or surgical pathway. Patients assigned to a non-surgical pathway will be allowed to mobilise according to the advice of their pelvic specialist and with the guidance of a physiotherapist using appropriate walking aids. This may involve a period where they are restricted from putting their full bodyweight through their pelvis. Patients will be reviewed by their pelvic specialist at 2 weeks following their injury, as per normal practice, to monitor for any movement in their fracture. Patients assigned to surgical management of their fracture will have surgery to stabilise the broken bones, using metalwork to fix the pelvis, performed at the earliest opportunity by a specialist pelvic surgeon. Following the surgery they will be able to mobilise as guided by their surgeon and a physiotherapist. This may involve a period where they are restricted from putting their full bodyweight through their pelvis. Follow-up of patients as part of the study will take place at 2 & 6 weeks, 3, 6, 9 and 12 months following randomisation. At all these time points they will be asked to complete the same series of questionnaires relating to their symptoms and daily activities completed when they initially agreed to take part in the study. Additionally patients will be asked to provide a few details on the rehabilitation they have received and any healthcare resources used (e.g. physiotherapy, GP visits etc) during their treatment. These questionnaires will be posted to patients at all time points. If no response is received then they may be completed by telephone with a member of the research team at the site at which they were recruited. Alternatively, at 6 weeks, 3 and 12 months, they may be completed with patients during their normal clinical review. At 6 weeks, 3 and 12 months, when patients are being reviewed by their pelvic specialist as part of their usual care, they will also be asked to complete a simple test of their walking ability with an independent assessor who is unaware of the treatment they have received. A small group of participants will be asked if they are willing to take part in a short interview to assess the acceptability of the study design, including the recruitment process, treatments and follow-up procedures. A group of staff involved in the recruitment and treatment of patients will also be invited to take part in a short interview to assess their views of the study treatments and study design. These interviews will help to inform the design of the future larger scale study. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure | The aim of this research study is to perform a feasibility study which will allow the researchers to plan a full definitive trial. A future trial will be deemed to be feasible if the overall recruitment rate is greater than 40% of potential participants per centre per month. The objectives of this feasibility study are; 1. To produce a CONSORT (consolidated standards of reporting trials) diagram, reporting screening, recruitment, randomisation compliance and include allocation proportions by centre 2. To confirm the recruitment rates and percentage of eligible patients who agree to take part 3. To collect outcome data at 2 & 6 weeks, 3, 6, 9 & 12 months post injury to collate the completeness and spread of the data at different time points post injury 4. To identify the outcome measure to be used as the primary outcome on the basis of completeness of data, sensitivity to change over time, the presence of floor or ceiling effects and patient acceptability 5. To develop and refine methods for the collection of resource use data relating to both management pathways 6. To explore patient and staff views of randomisation, treatment and trial processes using qualitative interviews |
| Secondary outcome measures | The outcome measures being assessed in this feasibility study for use in a future definitive trial are; 1. Iowa pelvic score – a measure specific to outcomes after pelvic injury 2. Oxford Hip score – a functional score for patients after hip/pelvic injury 3. EQ-5D-5L – a generic quality of life score 4. ICECAP-A – a measure of capability for the general adult population for use in economic evaluation 5. Brief Pain Inventory – a measure of pain severity and its effect on the patient All the above outcomes will be assessed at 2 and 6 weeks, 3, 6, 9 and 12 months to assess the most appropriate timepoints to be chosen for a future definitive trial. In addition the patients functional ability will be measured using the Timed Up and Go assessment carried out by a blinded assessor at 6 week, 3 months and 12 months. |

Results and Publications
| Intention to publish date | 31/12/2021 |
|---|---|
| Individual participant data (IPD) Intention to share | No |
| IPD sharing plan summary | Stored in repository |
| Publication and dissemination plan | The aim is to present the results from this feasibility study locally at each recruitment site, nationally at the Orthopaedic Trauma Society Annual meeting and also at the British Orthopaedic Association annual meeting to the general orthopaedic community. The results will be submitted for publication as an original article in a peer reviewed open access journal, possibly the BJJ (Bone & Joint Journal) or the JOT (Journal of Orthopaedics and Trauma). It is anticipated that potential publications will discuss the methodology of the study, including the outcome measures used and their ease of use by patients. As well as this it is hoped that the study will show the timepoint in patients recovery from these injuries where changes in their outcome are most significant and therefore the timepoint at which any primary outcome should be assessed. The study should also be able to provide some insight into patients views on the two treatment options and their willingness to be randomised to these treatments. |
| IPD sharing plan | The anonymised, full trial dataset will be stored on a REDCap database located on the University of Bristol servers. Access to the final trial dataset will only be available to members of the Trial Management Group (TMG) and Statistician. Individual sites will be given access to the dataset for their own recruited patients only. This will be made available following the final publication and on receipt of a written request to the TMG. Requests for other study documents will be considered by the TMG and should be made in writing to the contact details above. |
