Conservative Surgery for Diabetic Foot Osteomyelitis is not Associated With Longer Survival Time Without Recurrence of Foot Ulcer When Compared With Amputation

Abstract

Conservative surgery of diabetic foot osteomyelitis (DFO) in which bone infection is removed without amputation could minimize the biomechanical changes associated with foot surgery. We hypothesize that patients who undergo conservative surgery will have a longer survival time without recurrence of foot ulcers and further amputations than those who undergo any type of amputation to treat diabetic foot osteomyelitis. We assessed a retrospective cohort of 108 patients who underwent surgery for diabetic foot osteomyelitis from January 2011 to December 2012. Patients were followed-up until May 2020. No differences were found regarding either recurrence or new amputations in the analysed patients.

Conclusion: Conservative surgery is as safe as amputation to arrest bone infection in the feet of patients with diabetes. Conservative surgery was not associated with a lower rate of recurrence and new amputations than those patients who underwent amputations.
