Preservation Surgery of Septic Osteoarthritis and Osteomyelitis in the Diabetic Foot Using S53P4 Bioactive Glass—A Case Series

Abstract

(1) Background: Preservation surgery of the diabetic foot aims at tissue sparing to avoid further pathological changes from developing, while ultimately preserving the limb. For this purpose, osteoregenerative, antimicrobial, and osteostimulative materials are now available. The aim of this case series is to demonstrate several clinical situations in which the use of bioactive glass, a third-generation biomaterial, can potentially be of benefit. (2) Methods: In this retrospective case series, we present patients with a diabetic foot complication with septic osteoarthritis, treated at the University Medical Centre Ljubljana, in the years 2020–2022. Patients received surgical care with resection of the affected joint and bone and placement of bioactive glass material. We observed patient characteristics, recurrence of septic osteoarthritis or osteomyelitis, and the need for amputation in the follow-up period. (3) Results: Of the 16 included patients, 8 received treatment of the metatarsophalangeal joints, 4 of the midfoot joints, and 4 of the ankle joints. Ten suffered from Charcot neuroarthropathy. None required readmission within 30 days or suffered early complications. One complication with recidivant septic osteoarthritis and osteomyelitis was observed. (4) Conclusions: Our case series presents possible applications for treatment with bioactive glass in various joints and bones affected by septic osteoarthritis of the diabetic foot.
