Abstract
BACKGROUND It has been assumed that diabetic patients with peripheral neuropathy should not have pain associated with Charcot foot arthropathy. METHODS During a 19-year period, 14 diabetic patients (15 feet) presented for treatment with pain following resolution of the acute phases of midfoot Charcot foot arthropathy. All were clinically plantigrade with plain radiographic evidence of bony union without deformity. Pain did not resolve with the use of appropriate therapeutic footwear. When used, CT scans uniformly demonstrated nonunion. RESULTS All 14 patients had resolution of their presenting pain following successful arthrodesis. Nonunion was confirmed at surgery in all of the patients. One patient developed a fatal pulmonary embolus following removal of the external fixator. Two required late exostectomy for bony overgrowth at the surgical site of fusion for nonunion. CONCLUSION This small series of patients would suggest that nonunion of the Charcot neuroarthropathy process was responsible for complaints of pain not able to be managed with therapeutic footwear. Successful arthrodesis resolved the pain. CT imaging may help identify a treatable source of pain in this population.

Abstract
BACKGROUND There are uncertainties regarding the diagnostic criteria, optimal treatment methods, interventions, monitoring and determination of remission of Charcot neuro-osteoarthropathy (CNO) of the foot and ankle in people with diabetes mellitus (DM). The aims of this systematic review are to investigate the evidence for the diagnosis and subsequent treatment, to clarify the objective methods for determining remission and to evaluate the evidence for the prevention of re-activation in people with CNO, DM and intact skin. METHODS We performed a systematic review based on clinical questions in the following categories: Diagnosis, Treatment, Identification of Remission and Prevention of Re-Activation in people with CNO, DM and intact skin. Included controlled studies were assessed for methodological quality and key data from all studies were extracted. RESULTS We identified 37 studies for inclusion in this systematic review. Fourteen retrospective and observational studies relevant to the diagnosis of active CNO with respect to clinical examination, imaging and blood laboratory tests in patients with DM and intact skin were included. We identified 18 studies relevant to the treatment of active CNO. These studies included those focused on offloading (total contact cast, removable/non-removable knee high devices), medical treatment and surgical treatment in the setting of active CNO. Five observational studies were identified regarding the identification of remission in patients who had been treated for active CNO. We did not identify any studies that met our inclusion criteria for the prevention of re-activation in patients with DM and intact skin who had been previously treated for active CNO and were in remission. CONCLUSIONS There is a paucity of high-quality data on the diagnosis, treatment, and prognosis of active CNO in people with DM and intact skin. Further research is warranted to address the issues surrounding this complex disease.

Abstract
The aim of this paper is to review the recent literature regarding the epidemiology and surgical management of Charcot neuro-osteoarthropathy (CNO). We propose that a fundamental change in the approach and assumptions regarding the historical treatment of active CNO should be considered. Although the true incidence and prevalence of CNO in the US population with diabetes are not known, we estimated the incidence to be 27,602 per year and the prevalence to be 208,880 persons. In persons with diabetes, the incidence of CNO is higher than that of prostate, lung, kidney, and thyroid cancer, and in the entire US population, the incidence of CNO is higher than that of multiple myeloma, soft tissue sarcoma, and primary bone sarcoma. In persons with diabetes, the incidence of CNO is higher than fractures of the femoral shaft, distal femur, tibia, talus, calcaneus and Lisfranc ligament injuries. Surgical techniques have evolved over the past half century, and surgery is the standard for treating displaced fractures and intra-articular injuries. Since CNO is a fracture, dislocation, or fracture dislocation in patients with neuropathy, why do we treat CNO differently? Elsewhere in the skeleton displaced osseous and ligament injuries are treated surgically. Based on the information presented in this manuscript, we suggest that it is time for a paradigm shift in the treatment of persons with CNO. While uncommon, CNO in persons with diabetes is not rare. Given the advances in surgical techniques, surgical intervention should be considered earlier in persons with CNO who are at risk for developing deformity related foot ulceration.

Abstract
The International Working Group on the Diabetic Foot (IWGDF) has published evidence-based guidelines on the prevention and management of diabetic foot disease since 1999. This is the first guideline on the diagnosis and treatment of active Charcot neuro-osteoarthropathy in persons with diabetes published by the IWGDF. We followed the GRADE Methodology to devise clinical questions in the PACO (Population, Assessment, Comparison, Outcome) and PICO (Population, Intervention, Comparison, Outcome) format, conducted a systematic review of the medical literature, and developed recommendations with the rationale. The recommendations are based on the evidence from our systematic review, expert opinion when evidence was not available, and also taking into account weighing of the benefits and harms, patient preferences, feasibility and applicability, and costs related to an intervention. We here present the 2023 Guidelines on the diagnosis and treatment of active Charcot neuro-osteoarthropathy in persons with diabetes mellitus and also suggest key future topics of research.

Abstract
The aim of this study was to determine the validity and reliability of a vibration-based cell phone in detecting peripheral neuropathy among individuals with a risk of diabetic foot ulcer (DFU). The current study consisted of 3 phases: a pilot study, concurrent validity study, and interreliability study. A 128 Hz tuning fork and vibration-based cell phone using the Vibrations-Test app was compared in the primary care setting. The pilot study confirmed that the vibration-based cell phone has an adequate reliability (r > 0.70, P < .001). The concurrent validity test involved 96 participants (aged 55.78 ± 8.32 years). The Pearson correlation test found the highest correlation in the fifth metatarsal heads (r = 0.741, right feet; 0.772, left feet; P < .001). In the 4 primary care settings, the interrater reliability between nurses of the vibration-based cell phone were k = 1.000, 1.000, 1.000, and 0.720. The concurrent validity test found moderate to strong correlation results and that the interrater reliability had a strong agreement that was almost perfect. Thus, vibration-based cell phone applications can be used as screening tools for detecting neuropathy among individuals with a risk of DFU.

Abstract
Background Tibiotalocalcaneal arthrodesis or hindfoot fusion is a salvage surgical option used to treat symptomatic or severe deformity as a result of Charcot's arthropathy. It is an internal fixation that utilizes nails to stabilize the hindfoot after surgical correction of the deformity. This study intends to measure the change in functional outcomes of patients with Charcot's arthropathy using this technique and the time taken to achieve fusion. Method This study presents a series of 40 cases of Charcot's arthropathy where hindfoot fusion was done using a hindfoot arthrodesis nail. A retrospective analysis was done where these patients' functional scores had been evaluated preoperatively and postoperatively (serially) with the Short-Form Health Survey 36 (SF-36), American Orthopedic Foot and Ankle Society (AOFAS), Foot and Ankle Outcome Score (FAOS), and Foot Function Index (FFI). Along with its complication, the length of time required for the fusion is also reported. Results This study consists of 40 patients (13 men, 27 women; mean age 60.5 years; age range 52-68 years) with a mean follow-up of 64 months (range 24-108 months). The mean time taken for fusion was 5.1 months. All patients showed improvement in functional scoring (SF-36, AOFAS, FFI, and FAOS) postoperatively. We establish that the improvements were gradual over 2 years. Approximately 37.5% of patients had a minor complication and 2.5% had a major complication. Conclusion Hindfoot fusion using a hindfoot arthrodesis nail results in improved functional outcome with an acceptable fusion time and acceptable complication rate. Level of evidence Level III.

Abstract
BACKGROUND Five-year mortality and amputation frequencies after new-onset diabetic ulceration have been reported up to 55% and 74%, respectively. for patients with lower-extremity amputation. Following Charcot arthropathy, these frequencies were reported with wide variations. The aim of this meta-analysis is to provide a quantitative evaluation of amputation and mortality frequencies in a diabetic patient with a Charcot foot arthropathy. METHODS Electronic search strategy was applied on Medline, Web of Science, Cochrane Library and Google Scholar since inception to December 2021. Extracted data included study design, sample and patients characteristics, diabetes type and duration, lab results, ulcers at diagnosis, co-morbidities and follow up period. Meta-analysis reporting random-effects values was used to generate the weights results. RESULTS A total of 16 studies were included in the quantitative meta-analysis with a pooled sample of 2250 patients with 2272 Charcot feet. Two studies including 255 patients yielded a 1-year mortality frequency of 4% (95% CI = 0.018-0.065). Seven studies including 1706 patients reported a 5-year mortality frequency of 24.5% (95% CI = 0.172-0.326, I² = 88.5%). Four studies including 277 patients yielded a seven plus year mortality frequency of 16% (95% CI = 0.065-0.289, I² = 84.3%). Ten studies including 871 foot yielded an amputation frequency of 15% (95% CI = 0.067-0.258, I² = 93.6%) where 9% where major amputations (95% CI = 0.062-0.127, I² = 60%) and 5% were minor amputations (95% CI = 0.004-0.126, I² = 94.7%) CONCLUSION: Diabetic Charcot arthropathy yields marked risk of amputation and mortality. However, mortality frequencies were unexpectedly lesser compared to those related to the published frequencies associated with diabetic foot ulcers.

Abstract
Charcot neuroarthropathy can cause severe deformity of the midfoot, and intramedullary use of beams and bolts has been utilized as a method of definitive stabilization. This systematic review evaluated the outcomes of intramedullary beaming in patients with Charcot neuroarthropathy and determined the methodological quality of the studies. Four online databases were searched: PubMed, MEDLINE (Clarivate Analytics), CINAHL (Cumulative Index to Nursing and Allied Health) and Web of Science (Clarivate Analytics). To assess the methodological quality of the studies, the Coleman Methodology Score was used. The data was pooled into 2 outcomes groups for comparison: (1) Studies that reported on the outcomes of Charcot specific implants (study group). (2) Studies that reported on the outcomes using non-Charcot specific implants (control group). After screening, 16 studies were included. Compared to our control group, our study group had significantly higher rates of overall hardware complications, hardware migration, surgical site infection, reoperation, and nonunion. The study group had significantly lower rates of limb salvage compared to the control group. Our study and control groups did not differ in the rates of hardware breakage, wound healing complications, or mortality. The limb salvage rate was 92% and 97% of patients were still alive at a mean follow-up of 25 months. The mean Coleman Methodology Score indicated the quality of the studies was poor and consistent with methodologic limitations. The quality of published studies on intramedullary implants for Charcot reconstruction is low. Complications when utilizing intramedullary fixation for Charcot reconstruction are high, whether or not Charcot specific implants are used.

Abstract
The study aimed to evaluate the prevalence, characteristics and outcomes of patients affected by Charcot neuro-arthropathy (CN) and peripheral arterial disease (PAD) compared to CN without PAD. Consecutive patients presenting with an acute CN were included. The sample size was calculated by the power analysis by adopting the two-tailed tests of the null hypothesis with alfa = 0.05 and a value of beta = 0.10 as the second type error and, therefore, a test power equal to 90%. Seventy-six patients were identified. Twenty-four patients (31.6%) had neuro-ischaemic CN; they were older (66 vs. 57yrs), p = 0.03, had a longer diabetes duration (19 vs. 14yrs), p < 0.001, and more cases of end-stage-renal-disease (12.5 vs. 0%), p = 0.04 and ischaemic heart disease (58.3 vs. 15.4%), p < 0.0001 than neuropathic CN. Fifty patients (65.8%) had concomitant foot ulcers, 62.5% and 67.3% (p = 0.3), respectively, in CN with and without PAD. Neuro-ischaemic CN show arterial lesions of 2.9 vessels, and PAD was located predominantly below-the-knee (75%) but not below-the-ankle (16.7%). The outcomes for neuro-ischaemic and neuropathic CN patients were, respectively: wound healing (86.7 vs. 94.3%), p = 0.08; minor amputation (25 vs. 7.7%), p = 0.003; major amputation (8.3 vs. 1.9%), p = 0.001; hospitalization (75 vs. 23%), p = 0.0001. The study showed a frequent association between CN and PAD, leading to a neuro-ischaemic Charcot foot type. Neuro-ischaemic CN leaded to an increased risk of minor and major amputation and hospitalization, compared to neuropathic CN.

Abstract
Diabetes mellitus with the lack of glycemic control increases risks for developing comorbidities affecting organ systems responsible for critical function. The development of diabetic neuropathy predisposes patients to the onset of Charcot neuroarthropathy (CN). There is significant complexity with treatment of diabetic-induced CN, which can have an often delayed or missed diagnosis. Supervision and treatment from trained specialists are required to provide care for this multifaceted disease process. It is essential for patients to partner with glucose control, comorbidity prevention and care, as well as lower extremity management. Ultimately, CN can result in significant lower extremity deformity placing patients at risk of limb and life.

Abstract
The last decade has seen a significant development in early surgical intervention for patients with or at risk of ulceration owing to deformity resulting from the sequalae of diabetic foot disease. Midfoot Charcot neuroarthropathy is the most common deformity; its correction is enabled by specialized surgical implants designed to maintain surgical corrections. There has also been an increasing number of orthopedic foot and ankle surgeons, with a specific interest in diabetic foot disease who provide early surgical correction in patients identified as high risk. Minimally invasive surgery using percutaneous incisions completes the triumvirate, facilitating earlier surgical intervention to decrease reulcerations.

Abstract
Charcot neuroarthropathy secondary to diabetes mellitus is a serious complication, requiring specialist management. As a relatively rare pathology bearing similarity to other, more common diseases, it may be misdiagnosed at initial presentation, potentially leading to delays in appropriate management. We conducted a 2-part online survey of primary care physicians within an academic medical institution to assess knowledge of presentation, complications, diagnosis, and treatment of Charcot neuropathy. The first section was designed to assess physician knowledge of Charcot foot, while the second section was completed only by physicians who were familiar with the condition and was designed to gauge their level of knowledge. Most clinicians were familiar with Charcot, encountering it at least annually. They identified common signs of Charcot (eg, swelling, pain) and complications due to its mismanagement (eg, ulcer, amputation). However, there was some disagreement on how to diagnose the pathology, with some relying on film, others referring to specialists, and some saying they were unsure. There was uncertainty on when to choose surgical options; fewer than half referred to specialists for help with this decision, and a quarter were unsure how to make the decision. While, in general, clinicians were aware of Charcot and its characteristics, there was confusion regarding how to diagnose or appropriate nonsurgical treatment.

Abstract
Charcot foot (CF) is a rare complication of diabetes associated with foot deformities and foot ulcers. Peripheral arterial disease (PAD) is a factor of poor prognosis in patients with diabetic foot ulcers (DFUs). However, PAD has infrequently been studied in CF. We aimed to determine the prevalence, the characteristics and the prognosis of PAD in a large group of patients with diabetic CF. We retrospectively compared 56 patients with diabetic CF to 116 patients with diabetic foot without CF. The prevalence of PAD in patients with CF was 66.1%. Compared to patients without CF, patients with CF had similar risks to have PAD (OR 0.98, 95%CI 0.50-1.94, p= .97) and neuro-ischemic DFUs (OR 1.19, 95%CI 0.57-2.49, p= .65), more risk to have lesions of distal arteries (OR 4.17, 95%CI 1.76-9.94, p= .001) and less risk to need revascularization (OR 0.14, 95%CI 0.06-0.36, p< .001). In patients with CF, PAD was strongly predicted by DFUs (OR 24.55, 95%CI 1.80-334.43, p= .016) and coronary artery disease (OR 17.11, 95%CI 1.75-167.43, p =.015). Survival rate and limb salvage rate in patients with CF were not worsened by PAD and by neuro-ischemic DFUs, respectively. In conclusion, we show that PAD should not be overlooked in patients with diabetic CF, especially in those having DFUs or coronary artery disease. PAD in patients with CF differed from that of patients without CF since it predominated in distal arteries and required less often revascularization.

Abstract
Objective Charcot foot is a rare complication to neuropathy and can cause severe foot deformities and ulcerations, which often require prolonged antibiotical treatment. The objective of this retrospective study was to investigate whether this treatment is associated to impaired renal function. Results In total, 163 patients were included, of whom 105 (64%) had received β-lactam antibiotics for a mean total duration of 13.0 months. There was a significant increase in the urine albumin/creatinine ratio in the group that received antibiotics (p = 0.017), and the use of antibiotics was associated to a subsequent diagnosis of nephropathy (p = 0.01). Patients treated with antibiotics had a 21.9% risk of developing subsequent nephropathy versus 5.2% for patients not treated with antibiotics. We suggest increased awareness on signs of nephropathy in patients with severe Charcot foot.

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
The objective of this study is to compare risk adjusted matched cohorts of Charcot neuroarthropathy patients who underwent osseous reconstruction with and without diabetes. The 2 groups were matched based on age, body mass index, hypertension, history of end-stage renal disease, and peripheral arterial disease. Bivariate analysis was performed for preoperative infection, location of Charcot breakdown, and post reconstruction outcomes, in patients with a minimum of 1 year follow-up period. Through bivariate analysis, presence of preoperative ulceration (p = .0499) was found to be statistically more likely in the patients with diabetes; whereas, delayed osseous union (p = .0050) and return to ambulation (p ≤ .0001) was statistically more likely in patients without diabetes. The nondiabetic Charcot patients were 17.6 folds more likely to return to ambulation (odds ratio [OR] 17.6 [95% confidence interval {CI} {3.5-87.6}]), and 16.4 folds more likely to have delayed union (OR 16.4 [95% CI {1.9-139.6)]). Subanalysis compared well-controlled diabetic and nondiabetic Charcot neuroarthropathy patients for same factors. Multivariate analysis, in the subanalysis, found return to ambulation was 15.1 times likely to occur in the nondiabetic CN cohort (OR 15.1 [95% CI 1.3-175.8]) compared to the well-controlled diabetic CN cohort.

Abstract
Lack of vascularization is directly associated with refractory wound healing in diabetes mellitus (DM). Enrichment of endothelial precursor cells (EPCs) is a promising but challenging approach for the treatment of diabetic wounds. Herein, we investigate the action of nicotinamide riboside (NR) on EPC function for improved healing of diabetic wounds. Db/db mice that were treated with NR-supplemented food (400 mg/kg/d) for 12 weeks exhibited higher wound healing rates and angiogenesis than untreated db/db mice. In agreement with this phenotype, NR supplementation significantly increased the number of blood EPCs and bone marrow (BM)-derived EPCs of db/db mice, as well as the tube formation and adhesion functions of BM-EPCs. Furthermore, NR-supplemented BM-EPCs showed higher expression of sirtuin 1 (Sirt1), phosphorylated adenosine monophosphate–activated protein kinase (p-AMPK), and lower expression of acetylated peroxisome proliferator–activated receptor γ coactivator (PGC-1α) than BM-EPCs isolated from untreated db/db mice. Knockdown of Sirt1 in BM-EPCs significantly abolished the tube formation and adhesion function of NR as well as the expression of p-AMPK and deacetylated PGC-1a. Inhibition of AMPK abolished the NR-regulated EPC function but had no effect on Sirt1 expression, demonstrating that NR enhances EPC function through the Sirt1-AMPK pathway. Overall, this study demonstrates that the oral uptake of NR enhances the EPC function to promote diabetic wound healing, indicating that NR supplementation might be a promising strategy to prevent the progression of diabetic complications.

Abstract
AIM Diabetic neuro-osteoarthropathy (Charcot foot) is a serious form of diabetic foot syndrome, often leading to severe deformity of the foot and subsequently to ulcers and osteomyelitis. The aim of this retrospective study was to determine the success rate and long-term outcomes for a Charcot foot operation using external fixation in 115 individuals who underwent surgery between July 2008 and December 2012. METHODS Some 115 consecutive persons, 78 (68%) men and 37 (32%) women, were enrolled in this study. The eligibility criterion for this retrospective study was reconstructive foot surgery using a Hoffmann II external fixator in diabetic and non-diabetic neuro-osteoarthropathy. The main examination parameters in the follow-up were walking ability, amputation and mortality. Average follow-up was 5.7 (± 3.2) years. RESULTS Ninety-seven per cent of people were able to walk after the operation with bespoke shoes or an orthosis. At follow-up, 77% were able to walk and 51% were fully mobile even outside the home. Subsequent amputations were performed in 29 individuals (26%), with 17 (15%) minor and 12 (11%) major amputations. Forty-seven individuals died before follow-up, the majority (53%) from cardiovascular events. Average survival time post surgery was 4.5 (± 2.9) years. CONCLUSION Reconstruction surgery using external fixation is a very useful method for maintaining walking ability in the case of conservatively non-treatable diabetic and non-diabetic neuro-osteoarthropathy. Individuals with severe Charcot foot disease had a low rate of major amputations. Osteomyelitis was the main reason for major amputations.

Abstract
BACKGROUND Failed conservative treatment and complications are indications for foot reconstruction in Charcot arthropathy. External fixation using the Ilizarov principles offers a one-stage procedure for deformity correction and resection of osteomyelitic bone. The aim of this study was to determine whether external fixation with an Ilizarov ring fixator leads reliably to walking ability. MATERIALS AND METHODS 29 patients treated with an Ilizarov ring fixator for Charcot arthropathy were retrospectively analyzed. Radiologic fusion at final follow up was assessed separately on conventional X-rays by two authors. The association between walking ability and the presence of osteomyelitis at the time of reconstruction, and the presence of fusion at final follow up was investigated using Fisher's exact test. RESULTS Mean follow up was 35 months (range 5.3-107) months; mean time of external fixation was 113 days. Ten patients (34.5%) reached fusion, but 19 did not (65.5%). Two patients needed below knee amputation. 26 of the remaining 27 patients maintained walking ability, 23 of those without assistive devices. Walking ability was independent from the presence of osteomyelitis at the time of reconstruction and from the presence of fusion. CONCLUSION Foot reconstruction with an Ilizarov ring fixator led to limb salvage in 93%. The vast majority (96.3%) of patients with successful limb salvage was ambulatory, independent from radiologic fusion, and presence of osteomyelitis at the time of reconstruction. These findings encourage limb salvage and deformity correction in this difficult-to-treat disease, even with underlying osteomyelitis.

Abstract
BACKGROUND Charcot neuroarthropathy is a morbid and expensive complication of diabetes that can lead to lower extremity amputation. Current treatment of unstable midfoot deformity includes lifetime limb bracing, primary transtibial amputation, or surgical reconstruction of the deformity. In the absence of a widely adopted treatment algorithm, the decision to pursue more costly attempts at reconstruction in the United States continues to be driven by surgeon preference. QUESTIONS/PURPOSES To examine the cost effectiveness (defined by lifetime costs, quality-adjusted life-years [QALYs] and incremental cost-effectiveness ratio [ICER]) of surgical reconstruction and its alternatives (primary transtibial amputation and lifetime bracing) for adults with diabetes and unstable midfoot Charcot neuroarthropathy using previously published cost data. METHODS A Markov model was used to compare Charcot reconstruction and its alternatives in three progressively worsening clinical scenarios: no foot ulcer, uncomplicated (or uninfected) ulcer, and infected ulcer. Our base case scenario was a 50-year-old adult with diabetes and unstable midfoot deformity. Patients were placed into health states based on their disease stage. Transitions between health states occurred annually using probabilities estimated from the evidence obtained after systematic review. The time horizon was 50 cycles. Data regarding costs were obtained from a systematic review. Costs were converted to 2019 USD using the Consumer Price Index. The primary outcomes included the long-term costs and QALYs, which were combined to form ICERs. Willingness-to-pay was set at USD 100,000/QALY. Multiple sensitivity analyses and probabilistic analyses were performed to measure model uncertainty. RESULTS The most effective strategy for patients without foot ulcers was Charcot reconstruction, which resulted in an additional 1.63 QALYs gained and an ICER of USD 14,340 per QALY gained compared with lifetime bracing. Reconstruction was also the most effective strategy for patients with uninfected foot ulcers, resulting in an additional 1.04 QALYs gained, and an ICER of USD 26,220 per QALY gained compared with bracing. On the other hand, bracing was cost effective in all scenarios and was the only cost-effective strategy for patents with infected foot ulcers; it resulted in 6.32 QALYs gained and an ICER of USD 15,010 per QALY gained compared with transtibial amputation. As unstable midfoot Charcot neuroarthropathy progressed to deep infection, reconstruction lost its value (ICER USD 193,240 per QALY gained) compared with bracing. This was driven by the increasing costs associated with staged surgeries, combined with a higher frequency of complications and shorter patient life expectancies in the infected ulcer cohort. The findings in the no ulcer and uncomplicated ulcer cohorts were both unchanged after multiple sensitivity analyses; however, threshold effects were identified in the infected ulcer cohort during the sensitivity analysis. When the cost of surgery dropped below USD 40,000 or the frequency of postoperative complications dropped below 50%, surgical reconstruction became cost effective. CONCLUSIONS Surgeons aiming to offer both clinically effective and cost-effective care would do well to discuss surgical reconstruction early with patients who have unstable midfoot Charcot neuroarthropathy, and they should favor lifetime bracing only after deep infection develops. Future clinical studies should focus on methods of minimizing surgical complications and/or reducing operative costs in patients with infected foot ulcers.

Abstract
BACKGROUND The contralateral foot in Charcot arthropathy or neuroarthropathy (CN) is subject to increased plantar pressure. To date, the clinical consequences of this pressure elevation are yet to be determined. The aim of this study was to evaluate ulcer and amputation rates of the contralateral foot in CN. METHODS We abstracted the medical records of 130 consecutive subjects with unilateral CN. Rates of contralateral CN development and recurrence, contralateral ulcer development, and contralateral amputations were recorded. Statistical analysis was performed to identify possible risk factors for contralateral CN and ulcer development, and contralateral amputation. Mean follow-up was 6.2 (SD 4) years. RESULTS After a mean of 2.5 years, 19.2% patients developed contralateral CN. Female gender was associated with contralateral CN development (odds ratio 3.13, 95% confidence interval 1.27, 7.7). Overall, 46.2% patients developed a contralateral ulcer. Among the patients who developed contralateral CN, 60% developed an ulcer. Sanders type 2 at the index foot (midfoot CN) was significantly associated with contralateral ulcer development. Ulcer-free survival (UFS) differed significantly between patients with diabetes type 1 (median UFS 5131 days) and patients with diabetes type 2 (median UFS 2158 days). A total of 25 amputations had to be performed in 22 (16.9%) patients. Three of those 22 patients (2.3%) needed major amputation. CONCLUSION Almost 20% of patients developed contralateral CN. Nearly half of people with CN developed a contralateral foot ulceration. Patients with type 2 diabetes had significantly shorter UFS than patients with diabetes type 1. Every sixth patient needed an amputation, with the majority being minor amputations. The contralateral foot should be monitored closely and included in the treatment in patients with CN. LEVEL OF EVIDENCE Level IV, retrospective study.

Abstract
Diabetes is a systemic disease that has achieved epidemic proportions in modern society. Ulcers and infections are common complications in the feet of patients with advanced stages of the disease, and are the main cause of amputation of the lower limb. Peripheral neuropathy is the primary cause of loss of the protective sensation of the feet and frequently leads to plantar pressure ulcers and osteoarticular disruption, which in turn develops into Charcot neuropathy (CN). Common co-factors that add to the morbidity of the disease and the risk of amputation in this population are obesity, peripheral arterial disease, immune and metabolic disorders. Orthopedic surgeons must be aware that the early detection and prevention of these comorbidities, through diligent medical care and patient education, can avoid these amputations.

Abstract
Charcot neuroarthropathy (CN) is an unfortunate and common complication of patients with diabetes, most likely resulting from a lack of proper understanding of the disease, which leads to late diagnosis. It is commonly misdiagnosed as infection and treated with antibiotics and a frustrated attempt of surgical drainage, which will reveal only debris of the osteoarticular destruction. Proper education of diabetic patients and of the health care professionals involved in their treatment is essential for the recognition of the initial signs of CN. The general orthopedic surgeon is usually the first to treat these patients in the early stages of the disease and must be aware of the signs of CN in order to establish an accurate diagnosis and ensure proper treatment. In theory, this would make it possible to decrease the morbidity of this condition, as long as proper treatment is instituted early.

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
OBJECTIVE Arthroscopic tibiotalocalcaneal arthrodesis (TTCA) aims at reconstructing a pain-free, orthograde, and functional limb with reduced invasiveness and lower complication rates compared to open arthrodesis. INDICATIONS Combined osteoarthritis of the ankle and subtalar joint or hindfoot malalignment. CONTRAINDICATIONS Osteomyelitis/deep soft tissue infections, talus necrosis, severe deformity of hindfoot or distal tibia, pronounced boney defect, indication for combined total ankle replacement and subtalar fusion. SURGICAL TECHNIQUE Patient in supine position; arthroscopic debridement of the cartilage and subchondral zone, perforation of the subchondral bone marrow of the ankle and subtalar joint. Foot and hindfoot positioning. Special attention has to be paid to the calcaneus and talus inclination, hindfoot alignment and rotation. Temporary fixation, insertion of the guide wire, reaming and insertion of the retrograde, curved compression arthrodesis nail. If needed, autologous bone grafting. Proximal locking of the nail, application of compression, distal locking, wound closure. POSTOPERATIVE MANAGEMENT Lymphatic drainage, physical therapy, and restricted bed rest until wound healing. Non-weightbearing, immobilization for 8 weeks, then step-wise increase of weightbearing. Fitting of custom-made shoes. RESULTS Retrospectively included were 15 patients treated by arthroscopic TTCA with an intramedullary nail (average age 56 ± 10 years, 93% male, all had risk factors for postoperative complications). Due to a preoperative plantar ulceration, 4 patients (27%) had 3 ± 1.8 conditioning operations. Sufficient hindfoot correction was achieved in all patients. Major complications occurred in 33% (non-unions). In a subgroup analysis, the presence of a plantar ulceration significantly influenced the development of a major complication. In a case-control study, major complications occurred in 63% and wound complications in 50% of patients for the open technique compared to 33% and 0%, respectively, for the arthroscopic technique. Although the current data do not prove superiority of arthroscopic TTCA compared to open TTCA, there appears to be a strong trend towards considerably lower complication rates following arthroscopic TTCA.

Abstract
BACKGROUND Open tibiotalocalcaneal arthrodesis (TTCA) is associated to high complication rates, which led to the development of arthroscopic techniques. Aim was to compare complication rates of open to arthroscopic TTCA in high-risk patients. METHODS Single-center, retrospective case-control study. Patients were selected from the authors' TTCA database. Eligible were high-risk patients receiving arthroscopic-, or open TTCA retrospectively suitable for arthroscopic TTCA. Primary outcome were major complications. RESULTS Eight open and 15 arthroscopic TTCAs were included. Three open and 4 arthroscopic TTCAs presented preoperative plantar ulceration. Fusion rates were similar (75% vs. 67%; p=0.679). Major complications occurred in 63% of open (80% surgical-site-infections (SSI)) and 33% of arthroscopic (100% non-unions) TTCA. Preoperative plantar ulceration did not affect major SSI in open TTCA (67% vs. 60%) but resulted in a significant increase of non-union rates for arthroscopic TTCA (75% vs. 18%; p=0.039). In patients without plantar ulceration the union-rate was 80% for both, open and arthroscopic TTCA. CONCLUSION Arthroscopic TTCA drastically reduced major SSI. Patients without preexisting ulceration had excellent union-rates for open and arthroscopic TTCA.

Abstract
Charcot neuroarthropathy is a devastating consequence of diabetes mellitus and peripheral neuropathy. Because of its rarity, the condition is often misdiagnosed or poorly managed. When misadventure occurs, patients with Charcot neuroarthropathy can suffer ulceration, infection, amputation, and death. When patients have Charcot-related foot ulcers, the risks are amplified. Utilizing advanced electronic medical record analysis, a 30-month investigation was undertaken to determine if patients with diabetes mellitus and a concomitant diagnosis of Charcot-related foot ulcer were at greater risk of complications because of location setting of initial treatment for their condition. Charcot foot-related ulcers that are diagnosed in the outpatient setting had established foot specialist care. The outpatient management of the condition lead to a significant reduction in the amount of admissions to a higher acuity setting. However, patient outcomes did not vary once established and dedicated limb salvage efforts were employed. In this large contemporary population managed in a tertiary health system, patients with Charcot-related foot ulcer had negative outcomes when they were initially treated in an inpatient setting and had a significantly greater likelihood of readmission as compared with individuals who had established focused limb salvage care.

Abstract
The purpose of the present study was to demonstrate the effect of a delayed diagnosis of Charcot foot on acute care cost and usage. We used International Classification of Disease, Ninth Revision, Clinical Modification codes, and the California Office for Statewide Health Planning and Development 2009 to 2012 public patient discharge files to identify patients with type 2 diabetes mellitus and Charcot foot. The costs and length of stay were compared for those with a diagnosis of Charcot foot on admission compared with those who received a delayed diagnosis of Charcot foot before discharge. Patient demographic data, diagnoses often mistaken for Charcot foot, and procedures often performed for Charcot foot were assessed to determine the potential effect on costs and length of stay in Charcot foot subjects. A delayed Charcot foot diagnosis was associated with 10.8% greater inpatient costs and 12.1% longer length of stay. These patients required greater resource usage owing to the significantly greater number of procedures performed. A significantly greater number of patients underwent lower extremity amputation when the diagnosis was delayed, resulting in a 30.4% increase in costs and 31.6% longer length of stay. A greater rate of diabetic foot ulcers, foot infections, and osteomyelitis was also observed; however, the cost was only affected by osteomyelitis, and the length of stay was not significantly affected. A delayed diagnosis of Charcot foot at admission resulted in significantly increased acute care costs and longer lengths of stay.

Abstract
PURPOSE OF REVIEW Diabetes mellitus affects approximately 30.8 million people currently living in the USA. Chronic diabetes complications, including diabetic foot complications, remain prevalent and challenging to treat. We review clinical diagnosis and challenges providers may encounter when managing diabetic foot ulcers and Charcot neuroarthropathy. RECENT FINDINGS Mechanisms controlling these diseases are being elucidated and not fully understood. Offloading is paramount to heal and manage diabetic foot ulcers and Charcot neuroarthropathy. Diabetic foot ulcers recur and the importance of routine surveillance and multidisciplinary approach is essential. Several predictors of failure in Charcot foot include a related diabetic foot ulcer, midfoot or rearfoot location of the Charcot event, and progressive bony changes on interval radiographs. Patients with diabetic foot ulcer and/or Charcot neuroarthropathy are in need of consistent and regular special multidisciplinary care. If not diagnosed early and managed effectively, morbidity and mortality significantly increase.

Abstract
BACKGROUND Charcot foot is a rare but a serious diabetic condition. Recognition of this often overlooked condition to provide timely and proper management is important for a better prognosis. Limited data on Charcot foot was available in Asians. AIMS The aim of this study is to describe salient features and outcomes of Charcot foot in Thai patients. METHOD We presented our experience of 40 cases of Charcot foot patients who were treated from 2000 to 2016 at Theptarin Hospital, Bangkok, Thailand. RESULTS A total of 40 Charcot foot patients were identified (13 acute, 27 chronic; mean age 58.7 ± 10.2 years; duration of diabetes 18.0 ± 8.8 years; T2DM 95%). The average serum HbA1c level was 9.2 ± 1.9%. While acute Charcot foot was frequently misdiagnosed as cellulitis in almost one-third of patients, osteomyelitis was a leading cause of misdiagnosis in 15% of chronic Charcot foot patients. Ulcer-free rate at 6 and 12 months were observed in 60% and 58% of patients, respectively. The mortality rate was 13% during a median follow-up period of 57 months. Only 61% of the patients resumed walking normally while almost one-fourth of them were wheelchair-bound. CONCLUSIONS Charcot foot in Thai patients mainly developed in long-standing poorly controlled type 2 diabetes with neuropathy, and presented late in the course of the disease. It was often misdiagnosed resulting in improper management and poor outcome which included amputation.

Abstract
Charcot deformity is a challenge that foot and ankle surgeons struggle to manage successfully. Despite the advances in knowledge, technology, and treatment modalities, limb loss is still greater than 10%. This article discusses the efficacy of conservative measures and traditional surgical approaches. It proposes a multidisciplinary team approach, medical optimization, and lifestyle modification to put the patient in the best position to heal. Also discussed is the authors' staged surgical treatment protocol to enhance outcomes and decrease the rate of limb loss.
