Abstract
Surgical reconstruction of Charcot arthropathy in the foot and ankle is extremely difficult. The fundamentals of reconstruction are necessary to provide adequate outcome. Removing and resecting the diseased bone is needed along with good anatomic alignment and rigid fixation. This reconstructive surgery is not only difficult from medical management point of view but also involves patient compliance and good technical components of the surgery from the surgeon. The surgeon must have skills with internal and external fixation, a good understanding of lower extremity vascular disease, and a good understanding of infectious disease and plastic surgical techniques of the lower extremity.

Cates NK, Furmanek J, Dubois KS, Wynes J. Risk Factors and Outcomes After Surgical Reconstruction of Charcot Neuroarthropathy in Fracture Versus Dislocation Patterns. J Foot Ankle Surg 2022; 61:264-271. [PMID: 34366220 DOI: 10.1053/j.jfas.2021.07.020] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Revised: 07/15/2021] [Accepted: 07/20/2021] [Indexed: 02/03/2023]
Abstract
The primary aim of this study is to compare the preoperative risk factors and postoperative outcomes between Charcot neuroarthropathy patients with dislocation versus purely fracture pattern breakdown. The secondary aim is to compare the same factors between Charcot neuroarthropathy patients with dislocation versus fracture-dislocation pattern breakdown. A total of 55 patients with forefoot, midfoot, or hindfoot Charcot Neuroarthopathy were assessed at a mean follow up of 2.99 years. Bivariate analysis compared preoperative risk factors and postoperative outcomes, and segmented multivariable regression analysis was performed. Dislocation pattern Charcot had statistically significant higher rates of broken hardware (p = .05), mean age (p = .01), and revisional exostectomy (p = .01) compared to pure fracture pattern Charcot. Dislocation pattern Charcot was 12 times more likely to have revisions exostectomy (odds ratio [OR] 12.0, 95% confidence interval [CI] 1.84-78.37), and was 8 times more likely to have osteomyelitis (OR 7.8, 95% CI 1.4-42.7, p = .02) compared to the fracture-dislocation pattern Charcot. The patients with pure fracture pattern Charcot were 58.8 times more likely to have Charcot breakdown involvement of the talonavicular joint compared to the dislocation pattern cohort (OR 58.83, 95% CI 1.1-3220.3). Involvement of the talonavicular joint, in the fracture pattern Charcot associate with medial column collapse occurring at the onset of Charcot breakdown. The dislocation pattern in Charcot Neuroarthropathy demonstrated a higher propensity for residual collapse as demonstrated by the higher rates of broken hardware, osteomyelitis, and need for revisional exostectomy.

Abstract
Background: To identify differences in radiographic outcomes in weight-bearing lateral X-ray to predict the probability of ulceration in patients with midfoot Charcot neuroarthropathy (CN) differentiated by lateral and medial column deformities. Methods: Thirty-five patients who suffered from CN midfoot deformity participated in this 1 year prospective study in a specialized diabetic foot unit. Lateral talar-first metatarsal angle, calcaneal pitch, and cuboid height were performed by digital radiographs in the weight-bearing lateral view. Patients were followed up for 1 year or until an ulcer ulceration event occurred in the midfoot region. Results: ROC analyses showed that all patients with medial pattern deformity that developed a midfoot ulcer had a lateral talar-first metatarsal angle greater (negative) than −27.5 degrees (°). All patients with lateral pattern deformity that developed a midfoot ulcer had a calcaneal pitch greater (more negative) than −5° and a cuboid height greater (more negative) than −1.5°. Conclusions: Lateral talar-first metatarsal angle was the greatest predictor of midfoot ulceration, with greater than −27.5° measurement correlating with ulceration occurrence in patients with medial deformity. Calcaneal pitch and cuboid height were the greatest predictors of midfoot ulceration with greater than −5 and −1.5°, respectively in patients with CN lateral deformity.

Abstract
BACKGROUND Charcot's neuroarthropathy (CN) treatment is still controversial, and the results are controversial. Owing to patient comorbidities, surgical intervention carries a high risk of complications. Thus, foreseeing the possible results of planned treatment is crucial. We retrospectively evaluated the Charcot Reconstruction Preoperative Prognostic Score (CRPPS) in patients with surgically treated CN. METHODS Twenty-two feet of 20 patients were included in the study. Two groups were formed according to their CRPPS. Twelve patients with values less than 4 were defined as group A, and eight patients with values of 4 or greater were defined as group B. Mean follow-up was 61 months (range, 5-131 months). Groups were compared according to American Orthopaedic Foot and Ankle Society (AOFAS) scores, Foot and Ankle Disability Index (FADI) scores, and complication rates. RESULTS Group A and B mean AOFAS scores were 76.83 (range, 71-85) and 70.5 (range, 20-85), respectively. All of the patients were improved according to AOFAS and FADI scores, but no correlation was found with the CRPPS. None of the group A patients required additional intervention, but five patients in group B underwent revision surgery. No amputations were performed. CONCLUSIONS The CRPPS is focused on feasibility. The data needed to fill the scoring system is easily obtainable from medical records even retrospectively, and the score is helpful to predict a patient's outcome after CN-related surgery. Herein, CRPPS values of 4 or greater were related to high complication rates and lower functional outcomes.

Abstract
Charcot neuroarthropathy of the foot and ankle is associated with periarticular deformities and progressive radiographic changes. There have been studies analyzing the radiographic angulations and deformity progression in Charcot neuroarthropathy deformity. The aim of this paper is to provide systematic review of studies that evaluate foot and ankle radiographic parameters in patients with Charcot neuroarthropathy. A multidatabase search including, medline, EMBASE, Google Scholar, Cochrane Library, Clinicaltrials.gov and reference lists of included studies, was performed from 1980 to 2020. A total of 7 articles were included that analyzed radiographic angulations in Charcot neuroarthropathy deformity. The articles could be categorized into nonoperative angulation measurements, and pre- versus postoperative angulation measurements. The presence of ulcerations and the severity of the Charcot neuroarthropathy deformity were found to result from predominantly sagittal plane deformity. The deformity initiates with medial column collapse and progresses to continual lateral column collapse. Surgical intervention resulting in immediate postoperative improvement in angular measurements, however, without beaming of both the medial and lateral column, there was recurrence of the lateral column deformity. This systematic review of articles analyzing angular deformities in Charcot neuroarthropathy patients, demonstrates the progressive sagittal plane breakdown patterns of Charcot as well as the benefits of surgical intervention.

Abstract
Charcot neuroarthropathy is a debilitating condition that frequently leads to skeletal deformity and pedal ulceration in the insensate foot. Results are often poor and no clear guidelines for surgical management exist. Additionally, amputation rates vary widely making it difficult to accurately inform patients of risks. Few studies have assessed outcomes to identify patients for whom reconstruction is likely to fail. The literature is limited, with small sample sizes and mortality infrequently addressed. We performed a retrospective observational study of patients with Charcot neuroarthropathy to assess overall amputation and mortality rates at 30 days, 1 year, and 3 years postreconstruction and evaluated associated risk factors. Rates of infection, re-ulceration, and return to walking were also assessed. We identified 151 patients over a 5-year period. Demographic and clinical characteristics were collected. Descriptive statistics, Cox proportional hazard model, and logistic regression were used. Overall, 22 (14.6%) patients died, and 23 (15.2%) patients advanced to limb amputation postoperatively. End-stage renal disease, peripheral vascular disease, reconstruction during active phase Charcot process, and reconstruction at the ankle or subtalar joint were all associated with poor outcomes. The risk of mortality was 2.5 times higher in patients with end-stage renal disease, and 3.4 times higher among patients with peripheral vascular disease. Patients with ankle or subtalar joint reconstruction were 70% less likely to return to walking compared to medial column reconstruction. Due to these findings, we suggest that patients with such comorbidities be advised of increased risk for complications including failure to return to walking, amputation, and death.

Abstract
BACKGROUND Acute Charcot Neuroarthropathy (CN) is a destructive condition that is characterised by acute fractures, dislocations and joint destruction in the weight-bearing foot. The acute phase is often misdiagnosed and can rapidly lead to devastating health outcomes. Early diagnosis and management of CN is imperative to attenuate progression of this condition. Consequently, timely evidence-based assessment, diagnosis and management of acute CN is imperative. OBJECTIVE To identify the factors that impact the delivery of evidence-based care in assessment, diagnosis and management of people with acute CN. METHOD Systematic searches were conducted in four databases to identify studies in English that included factors that impact the delivery of evidence-based care in the assessment, diagnosis and management of people with acute CN. Articles and consensus/guideline documents were assessed for inclusion by the researchers and disagreements were resolved through consensus. Additionally backward citation searching was used to source other potentially relevant documents. Information relevant to the research question was extracted and thematic analyses were performed using qualitative synthesis. RESULTS Thirty-two articles and four additional consensus/guideline documents were included for data extraction and analyses. Information related to the research question was of expert opinion using the National Health and Medical Research Council (NHMRC) Levels of Evidence guidelines. Themes explaining practices that deviated from evidence-based care in assessment, diagnosis and management of acute CN centred around patient, health professional and health organisation/environmental. Delay to diagnosis is particularly influenced by the patient's knowledge of when to seek help, practitioner knowledge in knowing how to recognise and refer for appropriate immediate care, confusion in imaging and offloading and geographical and local health service resources to appropriately manage the condition. CONCLUSION Individual and health professional awareness and geographical barriers are key challenges to the effective delivery of evidence-based assessment, diagnosis and management of people with acute CN. Acute CN represents a medical emergency warranting the need for expedited assessment, diagnosis and management by appropriately trained health professionals in the appropriate.

J Clin Orthop Trauma 2021; 17:59-64. [PMID: 33680840 PMCID: PMC7919936 DOI: 10.1016/j.jcot.2021.02.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 02/02/2021] [Accepted: 02/07/2021] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Charcot neuroarthropathy (CN) of the midfoot was traditionally treated non-operatively with off-loading in a total contact cast (TCC). After introduction of the super construct concept, promising results were reported, however there is a need for further studies on this concept. Analysis of non-operative versus operative treatment is presented as well as our results from a consecutive series of 20 patients operated with the superconstruct concept. METHODS Twenty patients were operated from July 2017 until June 2020. Mean age was 58 years (50-80), mean weight was 116 kg (68-156), giving a BMI of 31 (26-45). Preoperative patients off-loaded in a TCC until decreased swelling and skin temperature measurement or ulcer had healed, mean 16 weeks immobilization. Surgery was without tourniquet, using a standard medial and lateral incision. Mean follow up is 24 (5-40) months. RESULTS Mean operation time was 227 (150-315) minutes. Medial column fusion was mandatory, in five cases as an isolated procedure, in 12 cases in combination with lateral column fusion and in three cases with a talocalcaneal fusion. Preoperative lateral Meary angle decreased from 23.5 to 9.6°, antero-posterior Meary angle decreased from 16.0 to 4.7°. Eight patients had postoperative incisional wound problems. Four patients had partial implant removal. All healed with a good clinical result. Two patients had an acute Charcot attack in the ankle joint during postoperative mobilization. One had a severe collapse of the talus resulting in a below knee amputation, giving an amputation rate of 5%. Radiographic examination at follow up, showed bone union of all patients. Nineteen patients are ambulated in orthopedic shoes at latest follow up, giving a 95% satisfactory result. CONCLUSION Superconstruct reconstruction of CN midfoot collapse is a safe procedure. There are incisional wound problems, recognition and fast treatment of these complications is important to achieve good results. There is a risk for overloading the ankle, initiating a new acute Charcot attack. Attention must be on this problem. The surgical technique is demanding and should be performed by experienced foot and ankle surgeons in a multidisciplinary team set up.

Skeletal Radiol 2021; 50:311-320. [PMID: 32699954 PMCID: PMC7736011 DOI: 10.1007/s00256-020-03541-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 06/30/2020] [Accepted: 07/05/2020] [Indexed: 02/02/2023]
Abstract
OBJECTIVE To develop a new magnetic resonance imaging(MRI) scoring system for evaluation of active Charcot foot and to correlate the score with a duration of off-loading treatment ≥ 90 days. METHODS An outpatient clinic database was searched retrospectively for MRIs of patients with active Charcot foot who completed off-loading treatment. Images were assessed by two radiologists (readers 1 and 2) and an orthopedic surgeon (reader 3). Sanders/Frykberg regions I-V were evaluated for soft tissue edema, bone marrow edema, erosions, subchondral cysts, joint destruction, fractures, and overall regional manifestation using a score according to degree of severity (0-3 points). Intraclass correlations (ICC) for interreader agreement and receiver operating characteristic analysis between MR findings and duration of off-loading-treatment were calculated. RESULTS Sixty-five feet in 56 patients (34 men) with a mean age of 62.4 years (range: 44.5-85.5) were included. Region III (reader 1/reader 2: 93.6/90.8%) and region II (92.3/90.8%) were most affected. The most common findings in all regions were soft tissue edema and bone marrow edema. Mean time between MRI and cessation of off-loading-treatment was 150 days (range: 21-405). The Balgrist Score was defined in regions II and III using soft tissue edema, bone marrow edema, joint destruction, and fracture. Interreader agreement for Balgrist Score was excellent: readers 1/2: ICC 0.968 (95% CI: 0.948, 0.980); readers 1/2/3: ICC 0.856 (0.742, 0.917). A cutoff of ≥ 9.0 points in Balgrist Score (specificity 72%, sensitivity 66%) indicated a duration of off-loading treatment ≥ 90 days. CONCLUSION The Balgrist Score is a new MR scoring system for assessment of active Charcot foot with excellent interreader agreement. The Balgrist Score can help to identify patients with off-loading treatment ≥ 90 days.

Abstract
OBJECTIVE A wide range of clinical presentations of Charcot neuroarthropathy of the foot with concomitant osteomyelitis in patients with diabetes has been described. Existing literature provides an equally diverse list of treatment options. The purpose of this systematic review was to assess the outcomes specifically for the surgical management of midfoot Charcot neuroarthropathy with osteomyelitis in patients with diabetes. METHOD A systematic review was conducted by three independent reviewers using the following databases and search engines: Cumulative Index of Nursing and Allied Health Literature (CINAHL), Cochrane Library, EMBASE (Excerpta Medica dataBASE), Google Scholar, Ovid, PubMed and Scopus. Search terms used were: Charcot neuroarthropathy, osteoarthropathy, neuro-osteoarthropathy, neurogenic arthropathy, osteomyelitis, midfoot, foot, ankle, diabetes mellitus, ulceration, wound, infection, surgical offloading, diabetic reconstruction, internal fixation, external fixation. Studies meeting the following criteria were included: English language studies, studies published from 1997-2017, patients with diabetes mellitus surgically treated for Charcot neuroarthropathy of the midfoot (specified location) with concomitant osteomyelitis, with or without internal and/or external fixation, follow-up period of six months or more postoperatively, documentation of healing rates, complications, and need for revisional surgery. Studies which were entirely literature reviews, descriptions of surgical-only technique and/or cadaveric studies, patients without diabetes, studies that did not specify location of osteomyelitis and Charcot neuroarthropathy, and treatment proximal to and including Chopart's/midtarsal joint specifically talonavicular, calcaneocuboid, subtalar, ankle were excluded. RESULTS A total of 13 selected studies, with a total of 114 patients with diabetes of which 56 had surgical treatment for midfoot Charcot neuroarthropathy with osteomyelitis, met the above inclusion criteria and were used for data extraction. CONCLUSION Surgical intervention for midfoot Charcot neuroarthropathy with osteomyelitis in patients with diabetes demonstrated a relatively high success rate for a range of procedures including debridement with simple exostectomy, arthrodesis with or without internal or external fixation, and advanced soft tissue reconstruction. However, this systematic review emphasises the need for larger, better designed studies to investigate the efficacy and failure rates of surgical treatment in this group of patients.

Abstract
With worsening diet and increasing prevalence of diabetes, patient encounters with Charcot neuropathic arthropathy (CNA) are expected to increase. Without intervention, the pathology progresses with further subluxation/dislocation and fracture, placing soft tissues at risk of preulceration or formal ulceration, infection, and potentially major amputation. The need to avoid amputation is of paramount importance. Although a formal single eradicating tool for CNA is lacking, there is capacity to intervene in ways that may curtail the pace of destruction. This article reviews understanding of the disease process and provides guidance to surgical reconstruction of the deformity.

Abstract
Understanding new theories of the epidemiology of Charcot neuroarthropathy is practice changing. Treatment of Charcot neuroarthropathy is evolving from a passive approach to one that sees the urgency of proactive, early recognition, thereby avoiding the cascading events that lead to the complex, limb-threatening deformities. Preventive medicine is the most efficient at avoiding severe deformity, with prolonged offloading and immobilization as the current mainstay of treatment. However, with recent advancements in medical and surgical modalities, this may become the treatment of the past as clinicians begin to favor medical management and early surgical intervention.
