Plain English summary of protocol

Background and study aims
An infected non-union (not fully healed) fracture in the lower or distal part of the tibia (shinbone) is a rare condition that can be disastrous. The neighbour joint could be affected and the bone axis could alter. Patients with this condition have to cope with pain, limited physical activity, inability to work and low quality of life. The goal of any surgical treatment is the eradication of the infection, dealing with any bone loss and the healing of the fracture. All the above should be planned and done at the same time. In case of treatment failure even amputation of the limb is an option. In this study, the Ilizarov method, a type of external fixation with circular frames, will be tested.

Who can participate?
Patients with an infected non-union fracture in the upper or distal part of the tibia

What does the study involve?
All participants undergo treatment of non-union and infection after surgical cleansing, antibiotic treatment and placement of the Ilizarov apparatus. The patient's clinical and functional outcomes and feelings of pain are measured before the surgery and afterwards throughout the follow-up period at regular intervals. The duration of follow-up is 36 months (3 years).

What are the possible benefits and risks of participating?
The goal of the treatment is fracture healing and infection eradication. This will improve the quality of life of the participant (return to work, return to daily or sports activity). Other options for these patients include arthrodesis (fusions of the bones resulting in a knee or ankle without any range of motion) or even amputation. As the Ilizarov method is approved and known for 80 years possible risks will not arise from the treatment itself but from the patients' other illnesses and the common risks of any other surgery.

Scientific titleTreatment of septic metaphyseal non-union of tibia using the Ilizarov method
Study acronymSePseT Ilizarov
Study objectivesThe Ilizarov apparatus completely and successfully treats septic pseudoarthrosis proximal and distal tibia metaphysis.
Ethics approval(s)1. Approved 30/09/2020, the General Hospital of Serres Ethics and Scientific Committee (3rd Km Serron-Dramas, Serres, Greece, 62100; +30 (0)2321094549; gnserres@hospserres.gr), ref: 09/21-09-2020
2. Approved 04/09/2020, the General Hospital of Drama Ethics and Scientific Committee (57 Ippokratous Street, 66100, Drama, Greece; +30 (0)25213 50300; iatriki.upiresia@dramahospital.gr), ref: 336/2020
Health condition(s) or problem(s) studiedPatients with closed epiphyses with metaphyseal non-union in tibia which are infected with pathogens
InterventionThe intervention studied is the treatment of pseudoarthrosis and infection after surgical cleansing, antibiotic treatment and placement of the Ilizarov apparatus. The patient's clinical and functional outcomes are taken into account as well as subjective feelings of pain and the change of all these preoperatively and postoperatively throughout the follow-up period at predetermined regular intervals. The duration of follow-up is 36 months (3 years).
Intervention typeProcedure/Surgery
Primary outcome measure1. Treatment success assessed using:
1.1. Healed fracture/non-union assessed using x-rays at pre-op, every month after Ilizarov removal and every 6 months up to the end of the follow-up period (min. 3 years)
1.2. Eradication of infection assessed using biomarkers (CRP, ESR, white blood count) at pre-op, every month after Ilizarov removal and every 6 months up to the end of the follow-up period (min. 3 years)
2. Treatment failure will be assessed by clinical examination and radiological evaluation monthly postoperatively until Ilizarov removal (end of the treatment period) and once per semester until the end of the follow-up period (3 years)
3. Side effects will be recorded when they appear either with modification of antibiotic therapy or calibration and cleaning of the Ilizarov device
Secondary outcome measures1. Functionality of the limb calculated with the AOFAS score/KOS-ADSL (Greek version) at pre-op, 1 month after Ilizarov removal and every 6 months up to the end of the follow-up period (min. 3 years)
2. Quality of life assessed with the Short Form-12 (Mental Health) at pre-op, 3 months, 6 months, 1 month after Ilizarov removal and every 6 months up to the end of the follow-up period (min. 3 years)
3. General lower limb condition measured using the AAOS Lower Limb Core Scale at pre-op, 1 month after Ilizarov removal and every 6 months up to the end of the follow-up period (min. 3 years)
4. Pain measured using the Visual Analog Pain scale once per month until the removal of Ilizarov device and once each semester until the end of the follow-up period
5. Quality of life measured using QALY analysis and the Time Trade-off index at pre-op, 1 month after Ilizarov removal and every 6 months up to the end of the follow-up period (min. 3 years), and EQ-5D-3L at pre-op, 3 months, 6 months, 1 month after Ilizarov removal and every 6 months up to the end of the follow-up period (min. 3 years)
6. Limb discrepancy, where it exists, measured clinically, radiologically and functionally with the use of wooden wedges (use of the ASAMI score for bone health and function of the limb) at pre-op, 3 months, 6 months, 1 month after Ilizarov removal and every 6 months up to the end of the follow-up period (min. 3 years)
