Charcot's foot, also referred to as Charcot arthropathy, is a significant complication of diabetes characterized by the gradual deterioration of a joint that bears weight, typically in the foot. Dealing with this condition can be quite tricky when it comes to diagnosis and treatment. It's important to give it the proper care and attention to avoid issues like ulcers and deformities.
Diagnosis
It's crucial to recognize the signs of acute Charcot arthropathy for timely intervention. If you notice symptoms like redness, warmth, swelling, or deformity without any skin breaks, it's important to be cautious, especially if you have peripheral neuropathy or renal failure. It's crucial to keep in mind that deformity might not always be visible, and discomfort may not be communicated in certain situations.
Referral
Referral to a Diabetic Foot Care Centre is crucial when Charcot's foot is suspected, ideally within one week of suspicion. These centres usually have a team that includes a surgeon, a physician, and an orthotist, each with their own unique setup. At this point, the diagnosis can be confirmed, and non-weight-bearing treatment can be started until definitive management can be carried out.
Confirmation
When it comes to confirming Charcot's foot and differentiating it from other conditions like osteomyelitis, diagnostic imaging, including X-rays and possibly MRI, is essential. When trying to determine a diagnosis, it's important to consider clinical clues like the location of bony changes and the presence of soft tissue wounds.
To deciding on treatment, factors such as imaging results and clinical assessment play a crucial role, especially when considering starting presumptive osteomyelitis therapy.
Acute Charcot Arthropathy
When dealing with acute Charcot arthropathy, it is common to use off-loading devices to alleviate pressure on the affected foot.
For off-loading devices, non-removable options are typically the top choice. However, in certain clinical situations, removable devices could also be taken into account. It's crucial to highlight that bisphosphonates are not typically advised for managing acute Charcot arthropathy unless within the context of a clinical trial.
Treatment Progress
Keeping track of the treatment progress is crucial to assess the resolution of acute Charcot arthropathy. One important aspect is conducting a clinical assessment, monitoring foot-skin temperature difference, and taking serial X-rays until the issue is resolved. When there's a slight temperature difference of less than two degrees centigrade between both feet and stable X-ray findings, it suggests that the issue is resolving.
Providing Specialised Care for High-Risk Individuals
Individuals with foot deformities resulting from previous Charcot arthropathy are at high risk of complications such as ulceration and require specialized care from Diabetic Foot Care Centres. These centres offer a range of services to ensure optimal foot health and prevent any potential complications.
Charcot's foot poses distinctive obstacles in both diagnosis and treatment, necessitating a collaborative effort and expert attention. By familiarising themselves with the diagnostic criteria, treatment options, and the importance of specialized care centres, this condition can be provide more effective care.
