Diabetic foot complications (DFC) such as ulcers and infection are the leading cause for non-traumatic non-oncologic amputations worldwide with a 5-year mortality reaching 70 %. Every attempt is warranted to preserve the limb for physical and psychological integrity of these patients. When possible to perform, conservative surgeries could save the foot and its function. This review will focus on those procedures that do not require in-depth surgical or microsurgical skills and that could be performed by general orthopedic surgeons. Along with the technical description and specific indication, a literature search was performed to locate the evidence in relation with the efficacy of these procedures. The procedures could be described in 3 categories: bony surgeries, soft tissue procedures and orthoplastic techniques. The bones surgeries include resection arthroplasty, metatarsal osteotomy, internal pedal amputation, distal Symes amputation, cement augmentation and partial or total calcanectomy. Soft tissue procedures include Achilles tendon lengthening, gastrocnemius recession, toe flexor tenotomy and tendon transfer. The reconstructive/orthoplastic techniques include skin grafting, local flaps, fillet flap and regional flaps, mainly the reverse sural flap. Though most of these conservative surgeries have been shown to yield good to excellent results, the indication for each surgery could be confusing. The role of the orthopedic surgeon is fundamental for the optimal treatment of DFC. Though most procedures are easy to learn and to perform without the need of extra surgical skills, mastering indications is key for successful outcomes. In addition, the knowledge of these limb preserving techniques could be paramount in rural areas or if no foot and ankle surgeons are available.

Diabetic foot complications are serious issues resulting from uncontrolled diabetes, primarily affecting the feet. Common complications include diabetic neuropathy, ulcers, PAD, Charcot foot, and gangrene. Preventive measures include controlling blood glucose levels, regular foot inspections, proper foot care, wearing appropriate footwear, and seeking prompt medical attention. A holistic approach to diabetic foot management is crucial due to the complex interplay of physiological, psychological, and environmental factors. Glycaemic control is essential for mitigating neuropathy and vasculopathy, while cardiovascular risk factors like hypertension and dyslipidemia are crucial for preventing complications. In South Africa, podiatrists play a crucial role in diabetic foot care, offering specialized expertise in the assessment, management, and prevention of foot complications associated with diabetes mellitus. They collaborate closely with other healthcare professionals to ensure comprehensive and coordinated care.Pharmacological management is a crucial aspect of podiatric care in the UK, where podiatrists use various medications to treat foot conditions effectively. In South Africa, podiatrists lack prescribing authority, leading to limited treatment options, dependency on referrals, and disparities in access to care. This fragmented approach can compromise patient outcomes, especially in chronic conditions like diabetes. To improve patient outcomes and promote optimal foot condition management, policy reforms, interdisciplinary collaboration, and professional advocacy efforts are needed.Policy recommendations for expanding podiatrist prescribing privileges include legislative reforms, regulatory framework updates, and professional accreditation. Legislative reforms could involve amending existing healthcare laws or introducing new regulations that recognize podiatrists as authorized prescribers. Regulatory framework updates should involve working with regulatory bodies to establish prescribing standards, prescribing limitations, and mechanisms for ongoing oversight and accountability. Professional accreditation should ensure educational programs for podiatrists incorporate training in pharmacology, pharmacotherapy, and prescribing practices to prepare graduates for the expanded scope of practice.Stakeholders in South Africa can improve diabetes management by advocating for policy reforms, professional recognition, and patient empowerment initiatives. By aligning policy, practice, education, research, and advocacy efforts, stakeholders can create a supportive ecosystem that fosters innovation, collaboration, and continuous improvement in diabetic foot care.

OBJECTIVE: Surgery plays a key role in the management of complicated diabetic foot disease (DFD). Currently, indications for medical versus surgical management are poorly defined. Prompt identification of patients who require surgery may reduce morbidities and length of hospital stay. This study aims to analyse factors in DFD that necessitate early surgical interventions.
METHODS: All patients admitted under a multi-disciplinary diabetic foot team in a tertiary institution over 2 years were included in a retrospective case-control study comparing patients who received medical management and patients who received surgical management. Logistic regression was performed to identify factors associated with surgical management of diabetic foot complications.
RESULTS: Three hundred and forty patients were included. 49% of patients required surgical management. Toe ulceration, elevated C-reactive protein (CRP), and the presence of osteomyelitis were associated with surgical management. Multivariate analysis calculated an odds ratio (OR) of 1.01 for CRP (p < 0.001), OR 2.19 (p < 0.019) favouring surgical management for forefoot ulcers, and OR 2.2 (p < 0.019) if osteomyelitis was present.
CONCLUSIONS: Patients with elevated CRP levels, a forefoot diabetic ulcer and established osteomyelitis were more likely to undergo surgical management. Prompt recognition of these patients has the potential benefit of earlier decision making in definitive surgical interventions.

OBJECTIVE: This study evaluated the toe and flow model (TFM), a limb preservation program led by podiatric surgeons in Alberta, Canada, for its impact on hospitalization rates and length of stay (LOS) in patients with diabetic foot complication (DFC). Diabetes, a leading cause of non-traumatic lower extremity amputations (LEAs) in Canada, often results in diabetic foot ulcers (DFUs), a major cause of infection, amputation, and hospitalization. TFM has reportedly reduced amputation rates by 39% to 56%.
METHODS: The study analyzed Alberta\'s health database from 2007 to 2017, focusing on diabetes patients aged 20 and above. It included patients with various DFCs and compared outcomes in regions using TFM and standard of care (SOC). The study also examined data from two major cities, one with TFM and the other without, including rural referrals to Calgary and Edmonton. The data were normalized for the diabetic population and analyzed using a standard Student\'s t-test.
RESULTS: TFM regions showed significantly lower hospitalization rates (p = 1.22E-12) than SOC regions. Over 11 years, TFM maintained lower average and median LOS by 0.13 and 0.26 days, respectively. TFM access reduced hospitalization risk by up to 30%, and patients in TFM regions had a 21% shorter LOS compared to SOC regions.
CONCLUSIONS: Despite similar demographics and healthcare systems, the TFM region benefited from a dedicated multidisciplinary program and comprehensive limb preservation services. The study shows that TFM effectively reduces hospitalizations and LOS for DFCs, with significantly better outcomes in the TFM region than in SOC regions.

OBJECTIVE: Major adverse cardiovascular event (MACE) outcomes associated with sodium-glucose cotransporter 2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptor agonist (GLP-1 RA) therapies remain unclear in patients with type 2 diabetes and newly diagnosed diabetic foot complications (DFCs). This study examined the impact of SGLT2i and GLP-1 RA use on the rates of MACEs and amputations in patients with type 2 diabetes and without cardiovascular disease.
METHODS: Data from the Taiwan National Health Insurance Research Database (2004-2017) were analyzed, focusing on patients with type 2 diabetes without previous MACE and newly diagnosed DFCs. The primary outcome was the first MACE occurrence, and the secondary outcomes included MACE components, all-cause mortality, and lower extremity amputation (LEA) rates.
RESULTS: SGLT2i users showed a significant decrease in the MACE (hazard ratio [HR], 0.64; 95% confidence interval [CI], 0.46-0.88) and hospitalization for heart failure (HR, 0.54; 95% CI, 0.35-0.83) rates compared with dipeptidyl peptidase-4 inhibitor users. The amputation rates were also lower in SGLT2i users without LEA at the first DFC diagnosis (HR, 0.28; 95% CI, 0.10-0.75) and did not increase in those with a history of peripheral artery disease or LEA. No significant differences were observed between dipeptidyl peptidase-4 inhibitor and GLP-1 RA users in terms of the primary or secondary outcomes.
CONCLUSIONS: In patients with type 2 diabetes initially diagnosed with DFC, SGLT2i are effective in significantly reducing the hospitalization for heart failure and MACE rates. SGLT2i lower the amputation rates, especially in patients who have not previously had a LEA, than the dipeptidyl peptidase-4 inhibitor therapy.

Increased ulcer risk diminishes the quality of life in diabetes. This study assessed abnormalities in foot plantar pressure distribution in adolescents with T1D to detect early signs of ulcer risk. A total of 102 T1D patients, without diabetic neuropathy, were included (mean age 17.8 years, mean diabetes duration 7.4 year). Pedography was captured using Novel emed. Data from the study group were compared with reference data. The study revealed a statistically significant reduced foot contact area in both feet in the entire foot and under the head of the fifth metatarsal bone and the second toe. In both feet, the peak pressure was increased under the entire foot, hindfoot, midfoot, first metatarsal head, big toe, and second toe. There was no statistically significant difference in peak pressure. The mean plantar pressure rating was statistically significantly increased in both feet across the entire sole, in the hindfoot, midfoot, and first metatarsal head. T1D patients of age near adulthood without neuropathy have increased values in mean pressure and reduced contact area, pointing to the need of monitoring and preventive measures. These results point to the need of further research and analysis which should include various risk factor such as foot anatomy, body posture, or certain metabolic factors.

Introduction. Unplanned readmissions are common following discharge in patients after hospitalization for diabetic foot disease (DFD) complications. The aim of this study was to identify factors associated with readmissions in these high-risk patients, treated in a multidisciplinary setting and the implication of measures that could effectively reduce readmission rates. Methods. Patients presenting with DFDs admitted between 2015 and 2017 were studied retrospectively in a single-centre patient database. The demographics and clinical comorbidities were analyzed and comparison was made between 2 groups: patients readmitted within 30 days of discharge and those who did not require readmission. Multivariate analysis was performed to identify risk factors associated with readmissions. Results. In total, 340 patients were included. The unplanned readmission rate was 10.9%. More than half of readmissions (71%) were related to wound deterioration and infection. In the readmission group, the patients had lower body mass index, higher rate of osteomyelitis, lower rate of debridement, and evidence of peripheral vascular disease below the knee in the index admissions but these were not significant. In the multivariate analysis, peripheral neuropathy was the only significant risk associated with unplanned readmissions (odds ratio: 2.78, 95% confidence interval: 1.23-6.29, P = .014). Conclusion. This study demonstrates a significant association between peripheral neuropathy and unplanned readmissions. The implications of this nonmodifiable risk factor in reducing readmissions include all levels of patient care delivery such as adequate preparation for discharge and transition back into the community. Recognition and education in successful long-term offloading of insensate diabetic feet may help reduce rates of unplanned readmission.

Background: Patients with diabetes mellitus (DM) are known to be predisposed to many complications in the lower extremities such as neuropathy, peripheral artery disease (PAD) and infection. Diabetic foot ulcers are complications of diabetes that can lead to lower extremity amputations, re-amputations and high mortality rates.Purpose: The aim of this study is to evaluate the risk factors associated with higher re-amputation rates in diabetic foot disease.Research Design: This is a mono-centric retrospective comparative study.Study Sample: the study included 136 patients, with a total of 193 procedures (111 primary amputations and 82 re-amputations) between 2011 and 2021.Data Analysis: The t-student test and Spearman correlation were used to look for mean differences and any relevant association, respectively. Multivariate logistic regression analysis was computed to look for independent variables.Results: Twenty-two (27%) and 60 (50%) of those who had major and minor amputations, respectively, had a re-amputation (p = 0.006). Besides diabetes (89%), the commonest risk factor associated with amputation was hypertension (86.7%), be it for primary amputation or re-amputation, followed by peripheral (PAD) and coronary artery diseases. Only three risk factors showed independent correlation with re-amputation; chronic kidney disease (r = 15%, p = 0.03), smoking (r = 15%, p = 0.03), and simultaneous presence of DM + PAD (r = 13.7%, p = 0.05).Conclusions: Factors that were significantly correlated with increased re-amputation rates have a clear pathologic pathway that affects vascularity and wound healing. Further studies should be aimed at developing a clear scoring system that can be used to stratify patient for re-amputation risk, and to better predict the results according to the severity of diabetes.

BACKGROUND: Diabetic foot amputations are a devastating outcome for any diabetic patient. They are associated with various risk factors, including failure to risk stratify the diabetic foot. Early risk stratification could lower foot complications risk at the primary healthcare level (PHC). In the Republic of South Africa (RSA), PHC clinics are the first entry point to the public healthcare system. Failure to correctly identify, risk categorise, and refer diabetic foot complications at this level may lead to poor clinical outcomes for diabetic patients. This study looks at the incidence of diabetic-related amputations at central and tertiary hospitals in Gauteng to highlight the case of the needed foot health services at the PHC level.
METHODS: A cross-sectional retrospective study that reviewed prospectively collected theatre records database of all patients who underwent a diabetic-related foot and lower limb amputation between January 2017 and June 2019. Inferential and descriptive statistics were performed, and patient demographics, risk factors and type of amputation were reviewed.
RESULTS: There were 1862 diabetic-related amputations in the period under review. Most patients (98 %) came from a poor socioeconomic background earning ZAR 0.00-70 000.00 (USD 0.00-4754.41) per annum. Most amputations, 62 % were in males, and the majority, 71 % of amputations, were in patients younger than 65. The first amputation was major in 73 % of the cases, and an infected foot ulcer was a primary amputation cause in 75 % of patients.
CONCLUSIONS: Amputations are a sign of poor clinical outcomes for diabetic patients. Due to the hierarchal nature of healthcare delivery in RSA, diabetic-related foot amputations could imply inadequate care of or access to diabetic foot complications at the PHC level in RSA. A lack of access to structured foot health services at PHC levels impedes early identification of foot complication identification and appropriate referral resulting in amputation in some of the patients.

Background The COVID-19 pandemic has a heavy burden on the approach of diabetic foot care worldwide. We aim to determine the impact of the COVID-19 outbreak on patients with diabetic foot (DF). Materials and methods This population-based cohort study included all patients diagnosed with the diabetic foot from 2019-2020 (pre-lockdown) and 2020-2021 (post-lockdown) in a tertiary center of Jeddah, Saudi Arabia. Results Among all the participants (n=358), a non-significant difference was found between amputation rate during and before the COVID-19 pandemic (P-value=0.0983). Also, it showed a significantly higher percentage of patients who had acute lower limb ischemia compared to those having it before the pandemic (P-value=0.029). Conclusions and relevance In conclusion, our study found that the COVID-19 pandemic was not associated with excess amputations along with mortality rate, as the management during the pandemic showed adequate diabetic foot care by improving the prevention methods through hospital protocol restrictions and facilitating access to virtual clinics.
