Progress in clinical diagnosis and treatment of diabetic Charcot neuroarthropathy of foot and ankle / 中国修复重建外科杂志

OBJECTIVE@#To summarize the progress of clinical diagnosis and treatment of diabetic Charcot neuroarthropathy (CNO) of foot and ankle to provide reference for clinical treatment.@*METHODS@#The research literature on diabetic CNO of foot and ankle at home and abroad was widely reviewed, and the stages and classification criteria of CNO were summarized, and the treatment methods at different stages of the disease course were summarized.@*RESULTS@#CNO is a rapidly destructive disease of bone and joint caused by peripheral neuropathy, which leads to the formation of local deformities and stress ulcers due to bone and joint destruction and protective sensory loss, which eventually leads to disability and even life-threatening. At present, the modified Eichenholtz stage is a commonly used staging criteria for CNO of foot and ankle, which is divided into 4 stages by clinical and imaging manifestations. The classification mainly adopts the modified Brodsky classification, which is divided into 6 types according to the anatomical structure. The treatment of diabetic CNO of foot and ankle needs to be considered in combination with disease stage, blood glucose, comorbidities, local soft tissue conditions, degree of bone and joint destruction, and whether ulcers and infections are present. Conservative treatment is mainly used in the active phase and surgery in the stable phase.@*CONCLUSION@#The formulation of individualized and stepped treatment regimens can help improve the effectiveness of diabetic CNO of foot and ankle. However, there is still a lack of definitive clinical evidence to guide the treatment of active and stable phases, and further research is needed.

Outcome of Surgical Fixation for Midfoot Charcot Neuroarthropathy - A Systematic Review

@#Introduction: Charcot arthropathy is a condition which is progressive, non-infectious, destructive and debilitating that commonly affect foot and ankle. This systematic review is to evaluate the occurrence of common outcomes associated with each intervention of Charcot neuroarthropathy in midfoot. Materials and methods: A systematic review on literatures that were published from Jan 2010 to Jan 2020 were collected, reviewed and selected regarding the surgical treatment procedures of Charcot neuroarthropathy in midfoot. Results: The initial search yielded 231 reports and after exclusion, nine out of the total studies were included in the outcome analysis for review. These were studies that included data concerning surgical reconstruction of Charcot arthropathy in the midfoot. Conclusion: It is suggested that soft tissue preparation and usage of combination of implants thus reduce the risk of infection as well as increase rigidity of construct, respectively. These factors will aid to improve outcome of midfoot Charcot arthropathy reconstruction.

Ataque de pie diabético. Descripción fisiopatológica, presentación clínica, tratamiento y evolución / Diabetic foot attack. Pathophysiological description, clinical presentation, treatment and outcomes

Resumen El ataque de pie diabético tiene una presentación aguda y grave que representa una amenaza para la conservación del miembro afectado e incluso para la vida del paciente. Es un término que surge por la necesidad de facilitar la identificación de aquellos pacientes que requieren intervención urgente, dándole un sentido de urgencia y gravedad, reforzando el concepto de que "tiempo es tejido". Se han identificado tres situaciones en las cuales urge este tipo de intervención: el ataque de pie diabético infectado, donde el pie se presenta con una infección grave y con rápida progresión de necrosis que requiere internación, un desbridamiento rápido de tejido desvitalizado, drenaje de colecciones y tratamiento antibiótico; el ataque de pie diabético isquémico que implica isquemia progresiva y evolutiva y requiere revascularización urgente, y la neuroartropatía de Charcot en fase aguda que demanda rápida identificación y descarga. El reconocimiento oportuno de dichas presentaciones es fundamental para iniciar un tratamiento adecuado y mejorar la evolución de los pacientes. En la presente revisión, se realiza una descripción de la fisiopatología, presentación clínica, tratamiento y evolución de los tres tipos de ataque de pie diabético.

Abstract Diabetic foot attack has an acute and severe presentation that threatens the affected limb and the patient´s life. It is a term that arises from the need to identify those patients that require urgent intervention; it conveys a sense of urgency and severity, reminding the term of "time is tissue". The classic presentation is that of a severe infected foot with rapidly progressive necrosis that requires urgent surgery to debride all necrotic tissue and purulent collections, providing an adequate antibiotic treatment. Ischemic diabetic foot attack that demands urgent revascularization and the acute Charcot neuroarthropathy for which primacy is given to diagnostic confirmation and off-loading are also considered atypical presentations of diabetic foot attack. The aim of identifying these diabetic foot presentations is to promote rapid intervention to provide adequate and effective treatment, avoiding the most feared complication which is the limb amputation. In the present review, a description of the pathophysiology, clinical presentation, treatment and evolution of the three types of diabetic foot attack is made.

Treatment algorithm for Charcot foot and surgical technique with circular external fixation / Algoritmo de tratamiento para el pie de Charcot y técnica quirúrgica con fijación externa circular

Abstract: Background: Charcot neuroarthropathy (CNA), commonly known as Charcot foot, is one of the most debilitating complications of diabetes mellitus. Patients with plantar ulcer and osteomyelitis (OM) due to Charcot foot represent a high cost for health systems and society in general. The amputation risk for ulcerated Charcot patients is 12 times higher than general population under 65 years old. Material and methods: In this article we present the CNA treatment protocol we use in our center. We also make a detailed description of the surgical technique «single stage surgery¼ with circular external fixation. Results: Our CNA treatment protocol covers the most common presentations of this severe neuropathic complication. With the «single stage surgery¼ using circular external fixation we achieve an ulcer-free foot, successful treatment of the OM, correction of the deformity, diminished the cost of treatment, avoided amputation and prevented recurrence of the ulcer. Conclusions: The use of a treatment algorithm based on the current literature, can be an invaluable tool in the treatment of these complex patients. The circular external fixation has proven to be the only reliable tool for treating complex Charcot foot in the context of poor bone stock, active ulcers, soft tissues problems and OM.

Risk factors for Charcot foot

Objective Diabetes mellitus is the main cause of Charcot neuroarthropathy and is clinically classified as follows: Charcot foot, acute Charcot foot (ACF) when there is inflammation, and inactive Charcot foot when inflammatory signs are absent. The aim of this study was to identify the risk factors for ACF in patients with type 2 diabetes mellitus.Materials and methods A matched case-control study was conducted to assess the factors associated with acute Charcot foot from February 2000 until September 2012. Four controls for each case were selected 47 cases of ACF and 188 controls without ACF were included. Cases and controls were matched by year of initialization of treatment. Conditional logistic regression was used to estimate matched odds ratios (ORs) and 95% confidence intervals (95% CIs).Results In multivariate analysis, patients having less than 55 years of age (adjusted OR = 4.10, 95% CI = 1.69 – 9.94), literate education age (adjusted OR = 3.73, 95% CI = 1.40 – 9.92), living alone (adjusted OR = 5.84, 95% CI = 1.49 – 22.86), previous ulceration (adjusted OR = 4.84, 95% CI = 1.62 – 14.51) were at increased risk of ACF. However, peripheral arterial disease (adjusted OR = 0.16, 95% CI = 0.05 – 0.52) of 6.25 (1.92 – 20.0) was a protective factor.Discussion The results suggest that PCA in type 2 diabetes primarily affects patients under 55 who live alone, are literate, and have a prior history of ulcers, and that peripheral arterial disease is a protective factor.

Ankle Arthrodesis using Cannulated Screws & Hybrid Type Rigid External Fixation in Diabetic Charcot Neuroarthropathy / 대한족부족관절학회지

PURPOSE: The diabetic charcot neuroarthropathy of ankle is an infrequent site (around 5%), but is definitely the location that, because of the instability and progressive deformity it involves, cause ulceration in a high percentage of patients, and this can then become a reason for amputation. However, the treatment of this disastrous disease is still challenging. We analyzed the clinical and radiological results of ankle arthrodesis by our fixation method in Charcot neuroarthropathy. MATERIALS AND METHODS: Seven cases that were diagnosed as charcot neuroarthropathy of ankle arthrodesis were followed for more than 16 months postoperatively. Mean age was 57 years, and the mean follow-up period was 27 months. Anterior approach was used in arthrodesis, and internal fixation by 3 or more cannulated screws and hybrid type external fixation were used. Auto iliac bone for grafting was combined in all cases. External fixator was kept for 3 months without weight-bearing. Then, boots brace was applied for more 3 months allowing partial weight-bearing. Four cases had minor complications such as pin site infection. Preoperative and postoperative AOFAS score, time to fusion and postoperative complications were checked. RESULTS: Postoperative fusion was completed in all cases, and the mean time to fusion was 3.4 months. No postoperative complication was checked. At the last follow-up, the mean AOFAS score had increased from 54 points to 72 points. Patient's satisfaction was over 80%. CONCLUSION: Satisfactory results were obtained after ankle arthrodesis using internal and hybrid type external fixation combined with auto iliac bone graft in charcot neuroarthropathy with minor complications.
