Comparative Analysis of Bone Resection Versus Bone Curettage in Diabetic Foot Osteomyelitis.

Abstract

This study aims to describe the healing times of patients who underwent bone resection compared to bone curettage for managing diabetic foot osteomyelitis and to compare short- and long-term complications. This analytical retrospective observational cohort study collected clinical records of patients from a specialized diabetic foot clinic who underwent resection or bone curettage between January 2017 and January 2022. After surgery, a 1-year follow-up was conducted to record healing times and short- and long-term complications. The study included thirty-one patients, with 19 (61.29%) undergoing resections and 11 (38.71%) undergoing bone curettages. The resection cohort had a mean healing time of 5.70 ± 6.05 weeks, whereas the curettage cohort had a mean healing time of 14.45 ± 11.78 weeks, showing a statistically significant difference (P = 0.011). No significant differences were observed in terms of short- and long-term complications. In the resection cohort, 12 (63.20%) experienced short-term complications, compared to eight (66.70%) in the curettage cohort (P = 0.842, χ² = 0.40, OR = 1.16). In the resection cohort, n = 6 (31.60%) had long-term complications, while n = 3 (25.00%) in the curettage cohort experienced long-term complications (P = 0.694, χ² = 0.155, OR = 0.72). Although there were no significant differences in short- and long-term complications between resection and curettage, the resection group showed shorter healing times.
