Brief Summary: The condition Charcot foot has been known in more than 130 years and yet there still remains a large effort to find the cause diagnostic and medical treatment of the condition

Charcot neuroarthropathy is a progressive disease of bone and joints characterized by often-painless bone and joint destruction in limbs that have lost sensory innervation The incidence of acute Charcot among diabetic patients is 02 the prevalence is 75 In the group of patients with neuropathy the prevalence is even higher -29

The diagnosis is often made on a clinical basis particularly in the early stages of the condition The aim of this study is to find a method that makes the diagnosis primarily on the basis of paraclinical information

Clinical presentation

The typical patients have had diabetes in 10 years and have distal symmetrical neuropathy

The common lesion is unilateral with an acute phase which may occur either spontaneously or be triggered by a minor trauma The foot becomes swollen warm red and oedematous Some patients have pain and the condition could be misdiagnosed as cellulites acute gout deep vein thrombosis and osteomyelitis If the patient has a foot ulcer it is important to rule out osteomyelitis and cellulites

In the initial phase it is difficult to make the right diagnose because Charcot is a rare condition This leads to a delay in the treatment of the Charcot foot which for the moment is reduction of weight bearing The patient is equipped with an air cast and the non weight-bearing regime is in some cases maintained in 12 months

The chronic Charcot is characterized by established deformity The deformity can be in different sites in the foot the most common is in the mid foot Because of the deformity there is abnormal weight pressure on the weight bearing sites on the foot This is associated with callus formation and there is a higher risk for ulceration
Detailed Description: Method

The investigation is a case control study where the aim is to test a set off clinical tests to see if the diagnose Charcot foot can be made paraclinical The assumption is that there are other parameter than the clinical observation that differ between the Charcot patient and a patient with polyneuropathy

The study will consist of a variety of examinations All patients will undergo a clinical examination by the same physician including a neurological status

The paraclinical examinations consist of blood samples x-ray of the foot if normal then MR-scanning of the foot skeletal Scintigraphy DEXA scanning distal blood pressure beat to beat examination to decide the autonomous neuropathy If the patient has a positive skeletal scintigraphy and ulceration on the foot or elevated infection parameter in the blood sample then a leukocyte scintigraphy will be performed in order to rule out osteomyelitis

The population that we will include in the study is divided in 5 groups

1 Patients with diabetes and acute Charcot foot
2 Patients with diabetes and chronic Charcot foot
3 Patients with diabetes and amputation of the first toe
4 Patients with diabetes and polyneuropathy
5 Patients with diabetes and without polyneuropathy All patients will undergo the full examination program with the exception of the cases mentioned above

Conclusions

There is need for a better diagnostic of the condition Charcot foot due to the severe longtime complication in form of disablement In some cases even amputation of the foot If the diagnosis is made earlier obviously one can start the intervention earlier and this will improve the survival of the foot

Another advantage is that agreed criteria for the diagnosis of Charcot would help in allowing comparison of different treatments
