Declining Incidence of Major Lower-Extremity Amputations in the Northern Danish Region Between 2016 and 2021: The Impact of Diabetes and Preventive Vascular Procedures.

BACKGROUND: Preventing lower-extremity amputations (LEAs) is pivotal. In the present study, we aimed to examine the recent trends in nontraumatic LEAs seen in the Northern Danish Region. METHODS: Using data from the regional Business Intelligence unit, we identified all nontraumatic LEAs (n = 689) performed in people above 50 years of age in the Northern Danish Region between January 2016 and December 2021 (approximately 600,000 inhabitants). Persons with diabetes (n = 26,025) were identified based on International Classification of Diseases-10 codes and data from the National Health Insurance Service Registry, while preventive vascular procedures (n = 1,097) were identified using surgical codes. Major LEA was defined as any amputation above the ankle. Incidence rates were expressed as events per 1,000 person-years. Trends were described as differences between the periods 2016-2018 and 2019-2021. RESULTS: A total of 249 (36%) major LEAs were performed in people with diabetes. People with diabetes were younger (71 vs 77 years, P < 0.001) and more frequently male (70% versus 54%, P < 0.001). Between 2016-2018 and 2019-2021, the incidence of major LEA declined from 1.76 (95% CI: 1.75-1.76) to 1.39 (1.39-1.39) in people with diabetes and from 0.47 (0.47-0.47) to 0.20 (0.20-0.20) in people without diabetes (all P < 0.001). Simultaneously, the incidence of preventive vascular surgery increased from 2.26 (2.26-2.26) to 3.48 (3.48-3.48) in people with diabetes and declined slightly in people without 0.49 (0.49-0.49) to 0.47 (0.47-0.47) (all P < 0.001). CONCLUSIONS: Despite significant declines in major LEA in both people with and without diabetes, most of the decline was driven by a large reduction in major LEAs in people without diabetes.

Experimental treatment with bone void filler for lower extremity insufficiency fractures in rheumatoid arthritis patients - Early clinical results.

Introduction: The aim is to report early clinical results of an experimental surgical procedure, injecting bone void filler, for patients with lower extremity rheumatoid arthritis (RA) insufficiency fractures. Case Report: We used a cross-sectional design with retrospective follow-up. Patient-reported outcomes were reported by the body-region specific questionnaires, knee injury and osteoarthritis outcome score (KOOS), or foot and ankle outcome score (FOAS). The Eq5D-5L questionnaire reported overall health-related quality of life (QoL). Furthermore, patient satisfaction (semi-structured interview), pain reactions, and adverse events were reported.Results from the first five patients were included. The median age was 70 years (range 50-80). Fracture localizations were proximal tibia (2), distal tibia (2), and distal femur (1). Four out of five patients reported a high degree of patient satisfaction following treatment. Four out of five patients at follow-up reported no pain from the fracture location. The median improvement from baseline to follow-up on the KOOS/FAOS subscale scores was pain 65 (range 42-69), symptoms 39 (range 25-50), the activity of daily living 41 (range 29-51), sport and recreational activities (sport/rec) 48 (range 40-60), and QoL 60 (range 57-72). The median improvement for the Eq5D index was 0.30 (range 0.26-0.36). Conclusion: Surgical treatment of insufficiency fractures in RA patients with bone void filler seems promising. Four out of five patients reported considerable improvement in function and QoL and substantially lower pain scores following treatment. More research is needed to investigate the efficacy of this novel surgical procedure.
