Abstract
Charcot neuropathic arthropathy is a degenerative, debilitating disease that affects the foot and ankle in patients with diabetes and peripheral neuropathy, often resulting in destruction, amputation. Proposed etiologies include neurotraumatic, inflammatory, and neurovascular. There has been no previous animal model for Charcot. This study proposes a novel rodent model of induced neuropathic arthropathy to understand the earliest progressive pathologic changes of human Charcot. High-fat-diet-induced obese (DIO) Wild-type C57BL/6J mice (n = 8, diabetic) and age-matched low-fat-diet controls (n = 6) were run on an inclined high-intensity treadmill protocol four times per week for 7 weeks to induce mechanical neurotrauma to the hind-paw, creating Charcot neuropathic arthropathy. Sensory function and radiologic correlation were assessed; animals were sacrificed to evaluate hindpaw soft tissue and joint pathology. With this model, Charcot-DIO mice reveals early pathologic features of Charcot neuropathic arthropathy, a distinctive subchondral microfracture callus, perichondral/subchondral osseous hypertrophy/osteosclerosis, that precedes fragmentation/destruction observed in human surgical pathology specimens. There is intraneural vacuolar-myxoid change and arteriolosclerosis. The DIO mice demonstrated significant hot plate sensory neuropathy compared (P < 0.01), radiographic collapse of the longitudinal arch in DIO mice (P < 0.001), and diminished bone density in DIO, compared with normal controls. Despite exercise, high-fat-DIO mice increased body weight and percentage of body fat (P < 0.001). This murine model of diet-induced obesity and peripheral neuropathy, combined with repetitive mechanical trauma, simulates the earliest changes observed in human Charcot neuropathic arthropathy, of vasculopathic-neuropathic etiology. An understanding of early pathophysiology may assist early diagnosis and intervention and reduce patient morbidity and mortality in Charcot neuropathic arthropathy.

Abstract
Neuropathic arthropathy is a pathology involving both upper and lower limbs. Different neurological diseases can cause this arthropathy. For instance, shoulder Charcot arthropathies are mostly associated to syringomyelia. The initial diagnosis of this arthropathy is difficult and often delayed in the presence of usually non specific symptoms. Since articular destruction is present in this disease, early diagnosis and primary management of the neurological condition is important, as it slows down the destruction of the joint.

Clinical features, radiological characteristics and offloading modalities in stage 0 Acute Charcot's neuroarthropathy - A single centre experience from South India. Diabetes Metab Syndr 2019; 13:1081-1085. [PMID: 31336448 DOI: 10.1016/j.dsx.2019.01.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2018] [Accepted: 01/14/2019] [Indexed: 11/27/2022]
Abstract
AIMS Stage 0 Acute Charcot's Neuroarthropathy (ACN)in Type 2 Diabetes patients is a challenging diagnosis with subtle clinical features and normal appearing plain radiographs of the affected foot. Delay in diagnosis can lead to progression of disease and irreversible deformities. There is a paucity of data on Stage 0 ACN from India. The aim of this study was to assess clinical and radiological characteristics and treatment outcomes in Indian Type 2 Diabetes patients with Stage 0 ACN. MATERIALS AND METHODS A comparative, case-control study was carried out amongst patients attending the Integrated Diabetes Foot Clinic at a tertiary care South Indian hospital. During the 3-year study period, a total of 1811 patients with Type 2 Diabetes Mellitus were screened. Of these, n = 10 patients with stage 0 ACN Charcot's arthropathy were identified based on clinical features and MRI imaging of the foot for confirmation of diagnosis. These were compared with an age and duration of diabetes-matched group of n = 50 patients without ACN as controls. RESULTS Our study identified 10 patients (0.5%) with Stage 0 Acute charcot neuroarthropathy (ACN) in the study population. Those with ACN had higher BMI, poorer glycaemic control and greater degree of peripheral neuropathy (p < 0.05). Clinically relative lack of pain and infrared thermometric temperature difference >2 °C in the affected foot were the most significant findings, while MRI foot was useful in early detection of active and severe stage 0 disease. Total contact cast was the preferred initial offloading modality, with delay in initiating complete immobilization leading to worse outcomes. CONCLUSIONS This is the first study to highlight the characteristic features of Stage 0 ACN in Indian Type 2 Diabetes patients. Thorough clinical evaluation, infrared thermometry and radiological findigs on MRI foot leads to early disease detection. Complete offloading, preferably with total contact casts can prevent disease progression and chronic deformities.

Abstract
AIMS To undertake a prospective point prevalence study of the prevalence of active Charcot neuro-inflammatory osteoarthropathy (Charcot disease) in a circumscribed part of England and to audit the time elapsing between disease onset and first diagnosis. METHODS The prevalence of active Charcot disease of the foot during a single month was assessed by specialist foot care teams at seven secondary care services in the East Midlands region of England. RESULTS A total of 90 cases were identified, representing 4.3 per 10 000 of the 205 033 total diabetes population of the region. The time elapsed from first presentation to any healthcare professional until diagnosis was also assessed. While the diagnosis was suspected or confirmed in one-third of patients within 2 weeks, it was not made for 2 months or more in 23 patients (24%). CONCLUSIONS Non-specialist professionals should have greater awareness of the existence of this uncommon complication of diabetes in the hope that earlier diagnosis will lead to lesser degrees of deformity.

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 The historic treatment of Charcot foot arthropathy has been immobilization during the active phase of the disease process, followed by accommodative bracing of the acquired deformity. Evidence derived from modern patient-reported outcomes investigations has convinced many surgeons to attempt operative correction of the acquired deformity with a goal of improving quality of life. METHODS Over a 12-year period, 214 patients (9 bilateral) underwent reconstruction of the acquired deformity associated with midtarsal Charcot foot arthropathy. Over time, 3 patterns of deformity were observed based on weight-bearing pattern, relationship of the forefoot to the hindfoot, and integrity of the talocalcaneal joint. A valgus deformity pattern was present in 138, varus in 48, and dislocation of the talocalcaneal joint in 37. A consistent operative strategy was employed. Surgery included percutaneous tendon-Achilles lengthening, resection of infection when present, attempted correction of the structural deformity by wedge resection at the apex of the deformity, and immobilization with a 3-level static circular external fixator. Additional deformity pattern-specific procedures were added over time. Clinical outcomes were based on the historic metrics of limb salvage and resolution of infection and the functional metric of the ability to walk with commercially available therapeutic footwear. RESULTS Seven patients died within a year of surgery, and 15 underwent partial- or whole-foot amputation. Overall, 173 of 223 feet (77.6%) achieved a favorable clinical outcome. Patients with a valgus deformity pattern were most likely to achieve a favorable clinical outcome (120 of 138, 87.0%). Patients with a dislocation pattern were less likely to achieve a favorable clinical outcome (26 of 37, 70.3%), and those with a varus deformity pattern were least likely to achieve a favorable clinical outcome (27 of 48, 56.3%). CONCLUSIONS Operative correction of the acquired deformity of Charcot foot arthropathy was performed with a goal of improving quality of life. Stratification of patients by deformity pattern allowed alterations of the basic surgery to afford improved outcomes. In addition to achieving historic goals of resolution of infection and limb salvage, almost 80% of the patients were able to achieve the functional goal of independent ambulation with commercially available therapeutic footwear. The clinical outcomes achieved in this retrospective case series appear to support the modern paradigm of operative correction of deformity in this complex patient population. This realistic appreciation of outcome expectations should both be helpful in counseling patients on the risk-benefit ratio associated with surgery and provide a benchmark to measure newer strategies of treatment. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
AIMS To determine local and systemic markers of inflammation and bone mineral density (BMD) in the foot and central sites in participants with diabetes mellitus and peripheral neuropathy (DMPN) with and without acute Charcot neuropathic osteoarthropathy (CN). METHODS Eighteen participants with DMPN and CN and 19 participants without CN had foot temperature assessments, serum markers of inflammation [C-reactive protein, (CRP) and erythrocyte sedimentation rate, (ESR)] and BMD of the foot, hip and lumbar spine at baseline and 1year follow-up. RESULTS CN foot temperature difference was higher compared to DMPN controls at baseline (4.2±1.9°F vs. 1.2±0.9°F, P<0.01) and after 1year (2.9±3.2°F vs. 0.9±1.1°F, P<0.01). Serum inflammatory markers in the CN group were greater at baseline and remained elevated 1year later compared to DMPN controls (CRP, P=0.02, ESR, P=0.03). All pedal bones' BMD decreased an average of 3% in the CN foot with no changes in hip or lumbar spine. DMPN controls' foot, hip and lumbar spine BMD remained unchanged. CONCLUSIONS Local and systemic inflammation persists 1 year after CN with an accompanying pedal osteolysis that may contribute to mid foot deformity which is the hallmark of the chronic Charcot foot.

Surgical management of Charcot neuroarthropathy of the ankle and hindfoot in patients with diabetes. Diabetes Metab Res Rev 2016; 32 Suppl 1:292-6.

Abstract
BACKGROUND Charcot neuroarthropathy (CN) of the ankle and hindfoot (Sanders/Frykberg Type IV) is challenging to treat surgically or nonsurgically. The deformities associated with ankle/hindfoot CN are often multiplanar, resulting in sagittal, frontal and rotational malalignment. In addition, shortening of the limb often occurs from collapse of the distal tibia, talus and calcaneus. These deformities also result in significant alterations in the biomechanics of the foot. For example, a varus ankle/hindfoot results in increased lateral column plantar pressure of the foot, predisposing the patient to lateral foot ulceration. Collapse of the talus, secondary to avascular necrosis or neuropathic fracture, further accentuates these deformities and contributes to a limb-length inequality. SURGICAL MANAGEMENT The primary indication for surgical reconstruction is a nonbraceable deformity associated with instability. Other indications include impending ulceration, inability to heal an ulcer, recurrent ulcers, presence of osteomyelitis and/or significant pain. Arthrodesis of the ankle and/or hindfoot is the method of choice when surgically correcting CN deformities in this region. The choice of fixation (i.e. internal or external fixation) depends on largely on the presence or absence of active infection and bone quality. CONCLUSION Surgical reconstruction of ankle and hindfoot CN is associated with a high rate of infectious and noninfectious complications. Despite this high complication rate, surgeons embarking on surgical reconstruction of ankle and hindfoot CN should strive for limb salvage rates approximating 90%. Preoperative measures that can improve outcomes include assessment of vascular status, optimization of glycemic control, correction of vitamin D deficiency and cessation of tobacco use.

Abstract
With the increased number of diabetics worldwide and the increased incidence of morbid obesity in more prosperous cultures, there has become an increased awareness of Charcot arthropathy of the foot and ankle. Outcome studies would suggest that patients with deformity associated with Charcot Foot arthropathy have impaired health related quality of life. This awareness has led reconstructive-minded foot and ankle surgeons to develop surgical strategies to treat these acquired deformities. This article outlines the current clinical approach to this disabling medical condition.

Abstract
INTRODUCTION Charcot neuroarthropathy may occur in patients with peripheral neuropathy who do not notice pain while their bones and joints collapse or breakdown under the constant pressure of body weight. This can lead to ulcerations from severe deformity and potentially limb-threatening and life-threatening infections. Current treatments vary from immobilization to extensive reconstructive surgical interventions. METHODS Serial casting, used to correct many pediatric deformities while bones are often more pliable, was used with a 63-year-old male patient who presented with an active phase of Charcot foot with ulceration. The patient previously underwent foot reconstruction and had all hardware removed prior to serial casting. Due to the potential pliability of the bones, serial casting was attempted to reform the shape and position of the foot in a reverse Ponseti-type serial casting to create a more stable structure with less deformity that could lead to epithelial breakdown. RESULTS The patient regained full ambulation with a plantargrade foot and no wounds, and was followed without complications for 36 months. CONCLUSION Serial weekly casting was an effective modality for treatment of this patient's Charcot foot deformity.

Abstract
Since the rarefaction of neurosyphilis, axial neuroarthropathy is mostly secondary to spinal cord pathologies. Peripheral manifestations of neuroarthropathy resulting from Guillain-Barré syndrome have already been reported but to our knowledge, this is the first case of a patient diagnosed with axial involvement. After the acute phase, a 47-year-old woman suffered of paraparesia with a partial loss of sensibility under the tenth thoracic vertebra. As a consequence, she developed first of all neuroarthropathy of both knees and few years later, a spinal involvement was discovered. Multiple surgeries of both knees and of the spine were required, due to non-union, relapse, and infection. Natural evolution of Charcot spine remains unknown. Surgical treatment is recommended but even with circumferential fusion, failures do frequently occur. This observation allows us to report an original case and to discuss the etiology of axial neuroarthropathy, the classical radiographic findings, and the inherent difficulties of its treatment.

Abstract
Charcot neuro-osteoarthropathy (CNO) is a devastating condition affecting most commonly the foot/ankle joint in diabetic patients and may lead to severe deformities and amputation. Peripheral sensory neuropathy seems to be a pre-requisite to the development of CNO. The aim of this review article is to summarise the skeletal effects of the nervous system on bone remodelling and fracture healing of normal and damaged joints and to describe how neuropathy, in the context of modern concept of neuro-osteopathology, is crucial in the predisposition of the patient to develop acute CNO.

Abstract
BACKGROUND Precise mechanism of developing neuropathic arthropathy known as Charcot's joint is not fully understood. CASE REPORT A 55-year-old Japanese woman with neurofibromatosis-1 complained of right gonalgia in December 2001. Physical examination revealed a huge tumor in the right lower leg without signs of inflammation. Laboratory findings were unremarkable. Radiographic examination disclosed the presence of osteoarthropathy in the right knee joint. In contrast, radiologic findings of the right foot and ankle were compatible with neuropathic arthropathy. Further investigations could not reveal abnormal findings in the nervous system. To improve patient's quality of life, partial resection of the tumor was performed. The resected tissues were compatible with neurofibromatosis without malignant transformation. The patient newly noticed pains in the right ankle and tarsal joints one year after the operation. Restricted mobility and insufficient blood supply in the right knee arising from the huge tumor might accelerate development of osteoarthropathy through malnutrition of the chondrocytes. Because the patient did not experience the arthralgia before the operation, the tumor might damage the peripheral nerves unabling to receive afferent signals from such joints resulting in neuropathic arthropathy. CONCLUSIONS The damaged peripheral nerves might be contributory to developing or accelerating neuropathic arthropathy.

Abstract
India has the highest number of people with diabetes in the world. Diabetic foot care is one of the most ignored aspects of diabetes care in India. Due to social, religious, and economic compulsions, many people walk barefoot. Poverty and illiteracy lead to usage of inappropriate foot wear and late presentation of foot lesions. Many nonphysicians are interfering in the treatment of diseases, including diabetes. Patients also try home remedies before visiting their physicians. We believe that rational improvisation is the key to success when working with diabetic foot patients in developing countries. We have developed several improvised techniques/approaches for diabetes care in general and specifically for foot care. Our techniques/approaches are based on four principles: 1) they are simple, 2) no special training is needed, 3) they are affordable, and 4) they are effective. Only simple and affordable methods are successful in the developing world.

MATERIALS AND METHODS Clinical data of 13 patients (mean age = 61.2 years) with Charcot arthropathy (CA, Eichenholtz 0) were compared with findings in native and contrast-enhanced MRI. 12 patients had diabetes mellitus (7 type 2, 5 type 1), one had idiopathic polyneuropathy. Evaluation was performed at acute stage of CA and at a 4 months follow-up. After baseline assessment, patients were treated with pressure-relieving means. Mean values of signal-intensity in short T1 inversion recovery (STIR) images of bones of the foot and ankle and corresponding contrast-enhancement were evaluated. Additional MRI-findings (soft tissue edema, varicosis, tenovaginitis, joint effusion) were analyzed. A correlation with symptoms (reddening, swelling, hyperthermia, pain) was performed. RESULTS Bone marrow edema in affected bones significantly decreased (p<0.001). Soft tissue edema and pain showed a significant correlation with intensity of bone marrow edema (p<0.05). The presence of bone marrow edema in the STIR sequence was strongly associated with a corresponding contrast enhancement (p<0.0001, kappa-coefficients 0.976 at baseline and 0.953 at follow-up). CONCLUSION MRI in early stage of CA provides valuable diagnostic information on the activity of the disease. A significant correlation of intensity of bone marrow edema in MRI and some clinical parameters (soft tissue edema and pain) was found. Paramagnetic contrast-agent did not provide additional information. This is the first report on quantitative assessment of signal alterations in stage 0 CA before and after treatment.

Abstract
The Charcot syndrome is a rare complication of neuropathy in diabetes and is characterized by an acute inflammatory episode of the foot that is associated with variable degrees of dislocation, fracture, and deformity. It has no single cause but represents the final common pathway in people who are predisposed to its development by the varying overlap of several different factors. The association of the active phase of the disease with inflammation, increasing osteopenia, and increasing calcification of the arterial walls strongly suggests, however, the involvement of the receptor activator of nuclear factor-kappaB ligand (RANKL)/osteoprotegerin (OPG) cytokine pathway, which is closely involved in all three processes. The evidence for increased expression of RANKL and OPG in diabetes and neuropathy as well as its potential significance is reviewed.

Abstract
Foot problems are common causes of morbidity in patients with diabetes mellitus. Foot ulcers are the leading cause of hospitalization in diabetic patients. Bones may be involved in two different clinical conditions: osteomyelitis and Charcot osteoarthropathy. Osteomyelitis usually develops by spreading from contiguous soft tissue to underlying bone. Charcot foot is deformation of foot as a result of muscle athrophy, bone and joint structure changes in a joint as a secondary complication of neuropathy. To distinguish bone infection from non-infectious bone disorders as in Charcot joint may be difficult, especially if there is no skin ulceration. So, the mere absence of skin ulcers does not exclude the diagnosis of osteomyelitis.

Abstract
BACKGROUND Charcot arthropathy is a chronic, progressive destructive process affecting bone architecture and joint alignment in people lacking protective sensation. The etiologic factors leading to progressive bone resorption have not been elucidated. The purpose of this study was to histologically examine surgical specimens with Charcot arthropathy for cell type and immunoreactivity of known cytokine mediators of bone resorption. METHODS Tissue samples of 20 specimens with known Charcot arthropathy were stained for Hematoxylin and Eosin (H&E) to quantify cell type. Nine of the specimens were stained with interleukin-1 (IL-1) antibody, nine with tumor necrosis factor (TNF) alpha antibody, and nine with interleukin-6 (IL-6) antibody. Distribution of staining was graded as focal (less than 10% of cells), moderate (10% to 50% of cells), and diffuse (more than 50% of cells) by two independent investigators. Inflammatory cells in tissue sections of rheumatoid synovium served as a positive control. RESULTS Osteoclasts were seen in excessive numbers lining the resorptive bone lacunae. There was a disproportionate increase in osteoclasts to osteoblasts in the Charcot-reactive bone. In each case, osteoclasts demonstrated immunoreactivity for IL-1, IL-6 and TNF-alpha with a grade of moderate or diffuse reactivity. CONCLUSION The findings of excessive osteoclastic activity in the environment of cytokine mediators of bone resorption (IL-1, IL-6, and TNF-alpha) suggest enhanced bone resorption through the stimulation of osteoclastic progenitor cells as well as mature osteoclasts. Alteration in the synthesis, secretion, or activity of these important regulatory molecules through the use of pharmacologic agents may, in turn, alter bone remodeling and loss and lead to accelerated healing without collapse or malalignment.

Abstract
Neuropathic arthropathy, also known as Charcot arthropathy, of the elbow joint is a rare and progressive joint disorder with little available information in the literature. Presentation and treatment data on 6 patients with this pathology are reviewed. In addition, outcome data are presented on all 6 patients at a mean follow-up of 51 months. Three of these patients had undergone surgical procedures for the treatment of their pathology. At the time of their latest follow-up, 2 patients had died but reported good pain relief and functional range of motion before their deaths. At a mean follow-up of 63 months, the remaining 4 patients also had minimal pain. Of these 4 patients, 3 reported moderate to gross instability in their elbows. Nevertheless, all 4 patients had good functional use of their arms with a mean Mayo Elbow Performance Score of 91. Our data suggest that surgical treatment of appropriate patients does not necessarily preclude a successful outcome. However, surgical treatment was also associated with an unpredictable course and a high rate of complications. Therefore, most patients with this pathology should be treated with nonoperative methods, and routine surgical intervention should be avoided.

Abstract
OBJECTIVE The aim of the study is to describe a group of patients with a highly destructive and asymptomatic form of psoriatic arthritis, mimicking a Charcot-like joint disease. METHODS We studied 180 patients with psoriatic arthritis and identified 4 patients with arthritis mutilans mimicking a Charcot-like joint disease. Clinical history, physical exam, and immunological testing were performed as well as X-ray of affected joints. Synovial membrane and sural nerve biopsies were performed and diagnosis of psoriasis was confirmed by skin biopsy. RESULTS Four patients with psoriatic arthritis mutilans according to Moll and Wright classification criteria (1) and Charcot-like joint disease were identified and evaluated. There were 2 males and 2 females, all Caucasians. The mean age +/- SD was 57.8 +/- 14.2 years. Mean arthritis duration +/- SD was 6 +/- 4.6 years and mean cutaneous duration +/- SD was 13 +/- 10.4 years. All patients had polyarthritis and a sudden onset of bilateral, painless, and highly destructive arthropathy involving large, non-weight bearing (elbows) and weight bearing (knees), and also small joint of hands and feet. Synovial membrane biopsy showed findings similar to those found in Charcot joint disease, including ischemic neuropathy. CONCLUSION A newly-recognized subset of patients with psoriatic arthritis and Charcot-like joint disease according to clinical, radiographic and histological features is described. The proposed neurovascular theory may explain the pathogenesis of this presentation.

Abstract
STUDY DESIGN Case report of an infected Charcot spine following spinal cord injury. OBJECTIVE To describe this very rare pathological condition and the results of surgical treatment. SETTING A department of orthopaedic surgery in Japan. METHODS A 44-year-old man presented with a destructive lesion in the lumbo-sacral spine and a fistula in his back. Anterior bone graft, percutaneous external spinal fixation, and suction/irrigation of the wound were performed. After 4 months, posterior spinal instrumentation surgery was carried out. RESULTS Primary closure of the fistula and complete bone fusion was achieved after the operation. CONCLUSION Infection of a Charcot spine, although a rare clinical entity, should be considered as a diagnostic possibility in the spinal cord-injured patients. External spinal fixation is a useful method for the unstable spinal lesion with infection.

Abstract
OBJECTIVE To assess diagnostic implications of abnormalities of the pedal digital tufts and to identify features to facilitate distinguishing of spondyloarthropathy and leprosy. BACKGROUND Better criteria for distinguishing between these disorders are necessary if their character, natural history, and evolution are to be understood. METHODS Pedal x rays of 91 consecutive patients with diabetes, 21 alcoholic patients, 100 with spondyloarthropathy, 8 with scleroderma, and 137 with leprosy, and 188 defleshed skeletons of individuals with alcoholism, syphilis, cerebrovascular disease, and paraplegia from the Terry and Hamman-Todd collections were examined for evidence of osseous and articular pathologies. Digital tuft abnormalities were divided into irregularity, divot, flattening, resorption, whittling, and fragmentation. RESULTS Tuft divots were more common in alcoholics than in diabetic, and were more common in both than in the other groups studied. Tuft flattening was limited to alcoholic and neurosyphilis groups. Tuft whittling was especially prominent among individuals with spondyloarthropathy, contrasted with leprosy and diabetes. Aligned fractures were more common in diabetics than individuals with leprosy. Misaligned fractures were limited to individuals with leprosy and neurosyphilis. Leprosy and spondyloarthropathy were complicated by phalangeal and metatarsal whittling more commonly than other diseases studied. Background pedal abnormalities, derived from individuals with cardiovascular syphilis, cerebrovascular accidents, and paraplegia, was limited to abnormal divots only. CONCLUSIONS Pedal digital tufts undergo a variety of pathological alterations useful in the recognition of disorders traditionally considered neuropathic in aetiology and in distinguishing differential considerations. Tuft flattening appears specific for alcoholism and neurosyphilis, and misaligned fractures seem specific for neurosyphilis and leprosy, providing differential assistance related to spondyloarthropathy. Conversely, periosteal reaction distinguishes spondyloarthropathy from leprosy.

Abstract
BACKGROUND Neurogenic Para-Osteo-Arthropathy (NPOA) occurs as a consequence of central nervous system injuries or some systemic conditions. They are characterized by bone formation around the main joints. METHODS In order to define some biological features of NPOAs, histological and immunohistological studies of the soft tissue surrounding osteoma and Ultrasound examination (US) of NPOA before the appearance of abnormal ossification on plain radiographs were performed. RESULTS We have observed a great number of ossifying areas scattered in soft tissues. US examination have also shown scattered ossifying areas at the early stage of ossification. A high osteogenic activity was detected in these tissues and all the stages of the endochondral process were observed. Mesenchymal cells undergo chondrocytic differentiation to further terminal maturation with hypertrophy, which sustains mineralization followed by endochondral ossification process. CONCLUSION We suggest that periosteoma soft tissue reflect early stage of osteoma formation and could be a model to study the mechanism of osteoma formation and we propose a mechanism of the NPOA formation in which sympathetic dystony and altered mechanical loading induce changes which could be responsible for the cascade of cellular events leading to cartilage and bone formation.

Abstract
The objective of this article was to review the magnetic resonance imaging (MRI) findings of four different neuroarthropathic extremities, and discuss the role of MRI in establishing a correct diagnosis. The shoulder, ankle, and knee had predominantly atrophic neuroarthropathic changes, whereas both atrophic and productive changes could be seen in the elbow. Bone marrow edema, suggesting a recent stress fracture, was detected in the elbow and knee. Osteochondral defects, or "detritic" synovitis with effusion, were extensive in all joints but exceptionally profound in the shoulder with amputation-like osteolysis and a total loss of the humeral head. Radiologists may encounter the joint manifestations of neuropathy, which may be confused with various pathologies, including tumor and septic arthritis, before the neurological diagnosis is established. MRI is helpful in detecting the extension of the disease as well as to differentiate chronic Charcot's arthropathy from septic arthritis before radiographic findings suggest the diagnosis.

Abstract
We report a case of neuropathic arthropathy caused by Arnold-Chiari malformation with syringomyelia, with details of the clinical and radiologic aspects. The patient had pain and stiffness in his left upper limb. MRI of the left shoulder revealed neuropathic arthropathy. Upon examination, his left elbow also had the characteristic findings for neuropathic arthropathy. Examination of the spinal cord by MRI confirmed Arnold-Chiari malformation associated with syringomyelia. Neuropathic arthropathy requires evaluation of the spinal cord to assess for occult causal lesions.

Abstract
Rheumatoid arthritis (RA) is one of the most critical articular diseases with synovial hyperplasia followed by impairment of quality of life. However, the mechanism(s) that regulates synovial cell outgrowth is not fully understood. To clarify its mechanism(s), we carried out immunoscreening by using antirheumatoid synovial cell antibody and identified and cloned "Synoviolin/Hrd1", an E3 ubiquitin ligase. Synoviolin/Hrd1 was highly expressed in the rheumatoid synovium, and mice overexpressing this enzyme developed spontaneous arthropathy. Conversely, synoviolin/hrd1(+/-) mice were resistant to collagen-induced arthritis by enhanced apoptosis of synovial cells. We conclude that Synoviolin/Hrd1 is a novel causative factor for arthropathy by triggering synovial cell outgrowth through its antiapoptotic effects. Our findings provide a new pathogenetic model of RA and suggest that Synoviolin/Hrd1 could be targeted as a therapeutic strategy for RA.

Abstract
Charcot joint is a disease that often occurs in patients with diabetes mellitus, tabes dorsalis, syringomyelia, chronic alcoholism, leprosy, trauma, or infection after fractures and dislocations. The treatment for Charcot joint has various complications, such as skin lesions, infections, and delayed union. We present our experience with a male patient who developed Charcot joint-like changes without diabetes mellitus or any other disease after an ankle fracture due to minor trauma.

Abstract
Diffuse idiopathic skeletal hyperostosis (DISH) is a chronic disease of the spine characterized by a significant association with metabolic alterations such as diabetes mellitus. Diabetes decreases the immunocompetence and increases the susceptibility to infections such as spondylitis, spondylodiscitis, and epidural abscess with spinal cord lesions in a high percentage of the cases. Microangiopathic changes of the intrinsic vasculature of the spinal cord are rare and mild. In a retrospective study of 784 acute spinal cord lesions, suspected diabetes could be found in only 13 patients. Neurophysiological and animal experiments as well as pathological studies have provided proof for the presence of diabetic myelopathy. Diabetic neuroarthropathy of the spine is rare, but important in the differential diagnosis of spinal disorders.

Abstract
Neuropathic arthropathy is a chronic, progressive joint degeneration with bone fragmentation, ligamentous instability, and dislocation. Diabetes is the leading cause of neuropathic arthropathy. Conventional radiography is the most commonly used imaging modality for diagnosing neuropathic arthropathy. The disease is mostly the hypertrophic type and is manifested by sclerosis of the bone, fragmentation, joint destruction, swelling, large joint effusion, and large osteophyte formation. Computed tomography, magnetic resonance imaging and radionucleide scintigraphy are helpful for diagnosing the disease and may help in distinguishing neuropathic arthropathy from septic arthritis and osteomyelitis.

Abstract
BACKGROUND Diseases exhibiting osteolysis in children are rare hereditary conditions. Several types have been recognised with different clinical manifestations. One type includes subcutaneous nodules, arthropathy and osteolysis and has been termed NAO syndrome. Previous radiological reports have described the affected bones, usually the carpal and tarsal regions, but a detailed analysis of the radiological findings of both the axial as well as the appendicular skeleton has not been reported. OBJECTIVES To describe the radiological findings in a large group of children with an autosomal recessive disease characterized by nodules, familial arthropathy and osteolysis. MATERIALS AND METHODS The study comprises 14 patients from 9 families and all patients had the triad of nodulosis, arthropathy and osteolysis (NAO). RESULTS The most common radiological manifestations were osteopenia, undertubulation of long bones, arthritic changes, sclerotic sutures of the calvaria, osteolysis and muscle contractures. Other common findings were squared vertebrae, broad medial clavicles and brachycephaly. Progress of disease was documented in more than half of the patients. CONCLUSIONS Our study is the first report of the detailed radiological findings of NAO syndrome. In NAO syndrome, both the axial and appendicular skeleton are involved

Abstract
Charcot neuroarthropathy is not uncommon in diabetic patients with peripheral neuropathy. Often, the condition is misdiagnosed for cellulitis or osteomyelitis and treatment is delayed. A high index of suspicion is required in these patients to initiate appropriate treatment early. This article covers the pathogeneses of this condition and briefly describes the recent studies performed to understand the underlying etiopathogenetic factors of this devastating condition. Lastly, it mentions the recently completed multicenter trial using bisphosphonates in diabetic Charcot neuroarthropathy.
