Background and study aims
Injury results in the death of approximately 5.8 million people each year, as well as severe disability for survivors, the majority of which occur in developing countries. A large proportion of these injuries are fractures or broken bones, with one of the commonest being broken leg bones. Sierra Leone is a country in West Africa and is one of the world’s poorest countries with a very weak healthcare system. There are limited treatment options for patients who break the bones in their legs and many of them have to live with disability or die from their injuries. This study aims to examine the treatment of broken tibia (shin) bones in the main government hospital of Freetown (Sierra Leone's capital), called Connaught Hospital. At present the treatment options for these fractures are casting with plaster of Paris and skin traction. For many of these fractures, this treatment is less than ideal, and often can result in prolonged hospital stay and poor function during and after treatment.

Who can participate?
Inpatients with broken shin bones in Connaught Hospital, Freetown

What does the study involve?
20 patients will undergo treatment as usual, with plaster of Paris and skin traction. The results of this will be compared with 20 patients who will receive a surgical intervention known as Ilizarov frame fixation. This involves a surgical procedure where the fracture is held in place by metal pins and an external frame to hold the broken pieces of bone steady while they heal. We think the benefit of this will be that the patient can walk quicker, get home from hospital quicker and have better bone healing and quality of life in the end. A large part of the study will look to see if the frame can be put in safely in Connaught and what are the costs and benefits of the frame compared to the current treatment. We hope the results will contribute to the implementation of a cost-effective and sustainable fracture fixation service in the future.

What are the possible benefits and risks of participating?
Patients will have to pay for their care like normal, including their time in hospital, doctor and nurse bills and food. The trial will pay for their follow-up visits at 30-days and 3-months, including transport expenses to get to the hospital. If the participant is in the group that receives the current treatment option, there are no particular added risks by taking part in this study. They will still need the follow-up appointments. If the participant is in the group receiving the operation and frame, there are additional risks associated with the surgical procedure and aftercare of the frame itself. These will be discussed in more detail during an extra operation specific consent process. However, participants in this group may be able to walk quicker, get home from hospital quicker and have better bone healing and quality of life.

Where is the study run from?
Connaught Hospital, Freetown (Sierra Leone)

When is the study starting and how long is it expected to run for?
April 2018 to June 2020

Scientific titleFeasibility of Ilizarov frame fiXation for closed Tibial fractures in Sierra Leone
Study acronymFIXT
Study objectivesUsing the Ilizaorv frame external fixation system can improve angular deformity in closed tibial fractures at 3 months post-intervention
Ethics approval(s)The trial is currently being reviewed by The University of Leeds School of Medicine Research Ethics Committee (MREC 18-001). We plan to submit the trial to the Sierra Leone Ministry of Health and Sanitation Scientific Research Ethics Committee in August 2018, and will not begin the trial until ethical approval has been granted from both these ethics bodies.
Health condition(s) or problem(s) studiedClosed tibial fractures
InterventionThe trial is a before and after study design with 40 patients in total (20 in each arm). The first 20 receive treatment as usual, which consists of plaster of Paris with or without traction and a total hospital stay up to 6 weeks. The second 20 receive operative fixation with the Ilizarov frame, which requires one operation and the expected length of hospital stay is a few days. The frame remains on as long as clinically needed, but typically 10-12 weeks for tibial fractures. All participants receive a follow-up at 30 days and 3 months post entry into the trial.
Intervention typeDevice
Pharmaceutical study type(s)
PhaseNot Applicable
Drug / device / biological / vaccine name(s)
Primary outcome measureThe fracture angular deformity at 3 months post-management, as defined by overall angular deformity on long leg alignment views via anteroposterior and lateral plain radiographs
Secondary outcome measuresThe following will be assessed after 30 and at 3 months post-management:
1. Length of hospital stay, defined as the time between registration into trial and actual discharge date or censored at end of trial follow-up
2. Date of being medically fit for discharge, defined as the time between entry into the trial and clinical assessment concluding the patient is medically fit for discharge or censored at end of trial follow-up
3. Time to fully weight bear, defined as the ability to mobilise unaided based on clinical evaluation by a member of the caring team
4. Time to patient rerun to work or pre-morbid responsibilities (e.g. caregiving) if not employed and is self-defined by patient
5. Patient self-reported functional status, assessed using the Lower Limb Functional Index (LLFI)
6. Quality of life, assessed using the EuroQol-5D (EQ5D)

Completion date01/06/2021
