RCT on Bioactive Glass S53P4 in Diabetic Foot Osteomyelitis in the Forefoot (DFORCT)

Summary

The Study will be a prospective multicenter randomized trial, focused on the management of acute and chronic Osteomilytis in Diabetic Foot patients. The aim of this Study will be to compare the effectiveness and safety of S53P4 bioactive glass, medical device class III used as per its CE mark indication and Instruction For Use, in the surgical management of OM in the forefoot performed as per local surgical standard of care, in the same indications in a group of Diabetic Foot patients admitted in highly specialized dedicated centers. Participants will randomized into two groups: * Patients in Group A will be treated with surgical removal of the affected bone, debridement of infected soft tissues and systemic antibiotic therapy targeted on the sampling on the bone during the surgical procedure, with or without use of bone substitutes (with the only exception of Bioactive glasses) according to the judgement of the operator as per normal practice. * Patients in Group B will be debrided as well and the infected bone will be debrided without eliminating completely the structure of the bone, but instead preserving the cortex, while all the soft bone visibly infected will be removed and then replaced with Bioactive glass, as per IFU, (S53P4 - Bonalive® granules and putty, Bonalive Biomaterials Ltd. Finland) and then closed for primary intention whenever possible.
