Post Market Study of Cerament V/G in Pedal Osteomyelitis
- Conditions
- Osteomyelitis - Foot
- Interventions
- Device: cerament V or G
- Registration Number
- NCT06628115
- Lead Sponsor
- Mid and South Essex NHS Foundation Trust
- Brief Summary
The goal of this clinical trial is to look at the outcomes of patients who have had bone infection of their feet treated with a licensed antibiotic paste. The main question it aims to answer is:
• How does the bone infection heal in response to the antibiotic paste?
Participants will:
* Undergo standard surgery to remove dead bone and drain any pus.
* Antibiotic paste is injected directly into the middle of the bone at surgery. This is instead of receiving antibiotics directly into their bloodstream for 6 weeks.
* Recieve one week of tablet antibiotics.
* Visit clinic 1 month after surgery for a normal clinical appointment. After, a research team member will ask the participant a few questions. The participant will also have a foot x-ray, wound photograph and fill out a short questionnaire.
* Visit clinic 6 months and 12 months following the surgery. A research team member will ask the participant a few questions. The participant will also have a foot x-ray, wound photograph and fill out a short questionnaire.

Group Intervention Description Cerament cerament V or G Cerament V/G implantation to forefoot or mid foot.
- Primary Outcome Measures
Name Time Method Freedom from clinical or radiological osteomyelitis in the same or adjacent bone (recorded as yes or no) 12 months post-implantion Clinical osteomyelitis:
positive bone biopsy in the setting of bone necrosis or purulent fluid containing pathogenic organisms emanating from exposed bone end.
Radiological osteomyelitis:
osteolysis or periosteal reaction on radiograph in affected or adjacent bone(s).
This is checked at each follow up visit, at 1, 6 and 12 months post-implantation.
- Secondary Outcome Measures
Name Time Method Surgical site infection requiring further course of antibiotics (recorded as yes or no) 12 months post-implantion If there is infection at the surgical site, requiring a further course of antibiotics, this will be recorded.
Major or minor amputation of study limb (recorded as yes or no with amputation details) 12 months post-implantion If major or minor amputation of study limb occurs, this will be recorded.
Serious adverse events related to Cerament V/G (number and type of event are recorded) 12 months post implantation A serious adverse event (SAE) refers to any expected or unexpected adverse event, related to ceramist, that results in any of the following outcomes: death, a life-threatening adverse event, requires inpatient hospitalisation (not required as part of the treatment) or prolongation of existing hospitalisation, a persistent or significant disability or incapacity, or cancer, or a congenital anomaly or birth defect.
Total treatment costs for osteomyelitis (total cost is calculated in GB pounds) 12 months post-implantation Treatment costs will be collected through the use of a Client Service Research Inventory focussed on surgical, community and further treatment costs over a 12 month follow up. These will be recorded by the patient as they occur and checked at each visit and cross reference with hospital medical records.
Wound healing (recorded as yes or no) 12 months post-implantation Wound is considered healed at 100% epithelialisation. This is checked at each follow up visit, at 1, 6 and 12 months post-implantation.
Wound area (measured in cm^2) 12 months post-implantation Wound area is measured at each follow up visit, at 1,6 and 12 months post-implantation, using an app called Imito measure.
Quality of life (measured using the EQ-5D questionnaire) 12 months post-implantation Quality of life is measured using the EQ-5D questionnaire. It is conducted at each follow up visit, at 1, 6 and 12 months post-implantation.
