The International Working Group on the Diabetic Foot (IWGDF) has consistently published evidence-based guideline recommendations on the prevention and management of diabetes-related foot complications. In 2023, the group published their first guidelines on the diagnosis and treatment of Charcot neuro-osteoarthropathy (CNO) in persons with diabetes. The guidelines highlight 26 recommendations based on 4 categories: diagnosis, identification of remission, treatment, and prevention of re-activation. As reviewed in the guidelines, there are 2 recommendations suggesting the use of temperature assessment and monitoring as a tool for management of patients with CNO. Utilizing the systematic review and the GRADE system of evaluation, the authors deemed the level of evidence around temperature monitoring and Charcot to be low with a conditional recommendation for use. The purpose of this manuscript is to summarize the IWGDF guidelines while highlighting the role of foot temperature monitoring. Several case examples are given to illustrate the use of temperature monitoring in patients with CNO. Until there are guidelines determining active vs quiescent CNO, skin temperature monitoring can be a fast, easy-to-use, and effective tool for the clinician.

Charcot\'s neuroarthropathy and osteomyelitis can have similar initial presentations. The ability to differentiate between the two pathologic conditions is essential, as each requires different treatment. We present a case of a 53-year-old woman with pain, swelling, and warmth in her left first metatarsophalangeal joint and first tarsometatarsal joint. Radiographs showed comminuted fractures at the base of the first metatarsal. Osteomyelitis was suspected by the primary team based on physical findings and a history of previous first metatarsophalangeal joint arthrodesis. A triphasic bone scan and an indium white blood cell scan were positive for osteomyelitis. The podiatric medical team was suspicious for possible Charcot\'s neuroarthropathy based on physical findings and uncontrolled blood glucose levels at the time of her previous arthrodesis. A sulfur colloid scan was performed and compared with an indium scan, which showed no evidence of osteomyelitis. This case demonstrates the usefulness of sulfur colloid imaging compared with an indium white blood cell scan to differentiate osteomyelitis from Charcot\'s neuroarthropathy. This case also highlights the importance of using clinical judgment to make the correct diagnosis.

BACKGROUND Charcot spine (CS), also called neuropathic arthropathy, appears to be triggered by damage to the nervous system (either central or peripheral) impairing proprioception and pain/temperature sensation in the vertebral column. Therefore, the defense mechanisms of altered joints lead to a progressive degeneration of the vertebral joint and surrounding ligaments, which can provoke major spinal instability. Beyond the sensory aspects, mechanic factors are identified as risk factors. While its etiology and pathophysiology remain contested, CS represents a rare and difficult pathology to diagnose at an early stage, owing to its nonspecific clinical symptoms. The diagnosis of CS is probably still underestimated and often occurs only quite late in the disease course. CASE REPORT An 83-year-old male patient who had a history of a post-traumatic tetraplegia was diagnosed with CS after 3 years, after describing a recent progressive worsening of neuropathic pain. The diagnosis was earlier than the majority of cases described in the literature. Indeed, in a recent review, the mean time lag between the onset of neurological impairment and the diagnosis of CS was 17.3±10.8 years. CONCLUSIONS This case report demonstrates the benefits of early diagnosis of CS when confronted by the clinical and radiological criteria. Therefore, it seems important to be able to evoke this neuropathic spinal arthropathy sufficiently in time to prevent its disabling consequences in patients with spinal cord injury, in terms of quality of life and independence.

BACKGROUND: Patients with diabetes and peripheral neuropathy have a 25% risk of developing a foot ulcer, and these can lead to soft tissue infections that worsen and result in osteomyelitis. While Charcot neuroarthropathy is not as common as osteomyelitis, it is often misdiagnosed as osteomyelitis.
METHODS: Three patients presented with diabetes, neuropathy, and foot ulcers. They underwent prophylactic surgery but later developed swelling at the surgical sites. Radiographs showed fragmentations that caused concern about osteomyelitis. The authors maintained diagnoses of Charcot neuroarthropathy and treated the patients with immobilization and offloading. All patients resolved the fragmentations without antibiotics or surgery.
CONCLUSIONS: While Charcot neuroarthropathy and osteomyelitis have similar signs and symptoms, understanding the similarities and differences between the conditions can aid providers in appropriate wound management.

Charcot neuroarthropathy (CN) is a serious diabetic complication with a poor prognosis and a high rate of misdiagnosis. Furthermore, beta(2)-microglobulin amyloidosis (Abeta2M) makes the diagnosis and therapy more difficult and complex. This case report highlights the pathophysiology, clinical evaluation, treatment, and prevention of the major diabetic complications associated with CN and Abeta2M that cause poor quality of life, limit the patient\'s ability to walk independently, and are directly or indirectly linked with a high risk for lower limb amputation. Ankle CN was discovered in a 36-year-old single female with a history of type 1 diabetes mellitus and diabetic nephropathy. We performed early internal fixation. However, because she lived alone and needed hemodialysis three times a week, wearing a brace and non-weight-bearing were extremely inconvenient. Furthermore, she did not experience any pain and only some edema; thus, she proceeded to bear weight ahead of schedule without authorization. Due to the premature weight-bearing and poor compliance, the patient suffered severe bone resorption and infection and eventually had to undergo amputation. Abeta2M was suggested by bone pathological sections. We present a case of failed internal fixation of ankle CN with Abeta2M, emphasizing the importance of social factors and postoperative management.

An adolescent girl came with swelling of both thighs with difficulty in walking for a few months. Based on clinical, and radiological evaluation and nerve conduction studies, she was diagnosed to be having bilateral hips Charcot\'s arthropathy due to hereditary sensory autonomic neuropathy type 4. Other common causes of Charcot arthropathy were ruled out. The patient was conservatively managed and parents were educated about preventive measures. Through this case report, we want to highlight the myriad number of manifestations and clinical presentations of a child presenting with hereditary sensory autonomic neuropathy type 4.

Charcot neuropathic arthropathy is a relatively rare, chronic disease that leads to joint destruction and reduced quality of life of patients. Early diagnosis of Charcot arthropathy is essential for a good outcome. However, the diagnosis is often based on the clinical course and longitudinal follow-up of patients is required. Charcot arthropathy is suspected in patients with suggestive symptoms and an underlying etiology. Failed spinal surgery is not a known cause of Charcot arthropathy. Herein we report a patient with ankle Charcot neuropathic arthropathy that developed after failed spinal surgery. A 58-year-old man presented to the emergency room due to painful swelling of the left ankle for 2 weeks that developed spontaneously. He underwent spinal surgery 8 years ago that was associated with nerve damage, which led to weakness of great toe extension and ankle dorsiflexion, and sensory loss below the knee. CT and T2-weighted sagittal MRI showed a fine erosive lesion, subluxation, sclerosis, fragmentation, and large bone defects. Based on the patient\'s history and radiological findings, Charcot arthropathy was diagnosed. However, the abnormal blood parameters, positive blood cultures, and severe pain despite the decreased sensation suggested a diagnosis of septic arthritis. Therefore, diagnostic arthroscopy was performed. The ankle joint exhibited continued destruction after the initial surgery. Consequently, several repeat surgeries were performed over the next 2 years. Despite the early diagnosis and treatment of Charcot arthropathy, the destruction of the ankle joint continued. Given the chronic disease course and poor prognosis of Charcot arthropathy, it is essential to consider this diagnosis in patients with neuropathy.

Charcot neuroarthropathy (CN) is a destructive complication of the joints in patients with diabetes and should be managed from the onset of the first symptoms to avoid joint deformity and the risk of amputating the affected joint. Here, we describe the case of a young 24-year-old patient living with type I diabetes who developed active bilateral CN in both tarsal joints. This case of neuroarthropathy was uncommon due to the bilateral presentation at the same level of the joint. Despite the patient consulting from the beginning of the symptoms, none of the physicians suspected or diagnosed CN, leading to a delay in management and the aggravation of bone destruction by CN. This highlights the importance of early management of CN with the need to refer people with suspected CN to specialised diabetic foot care centres.
