Abstract 

Aim:
Available literature on the prevalence of Charcot arthropathy represents mainly western population. No study has been reported from India so far. Hence we attempted to study the prevalence of Charcot arthropathy (CA) in patients with type 2 diabetes mellitus and severe peripheral neuropathy (T2DMPN), belonging to Indian population amongst which type 2 diabetes is on the rise in alarming proportions.

Methods: 
Medical records of 3387 patients who performed an objective vibration perception threshold during the year 2015 were screened for T2DMPN. Those of 1475 of T2DMPN patients above 50 years were selected and analyzed in detail for CA. CA was diagnosed based on clinical features and/or radiological investigations. The anatomical localization of the disease distribution of the affected foot was done according to Brodsky's classification. 

Results:
The prevalence of CA in T2DMPN was found to be 9.8%. The mean age of patients diagnosed with CA was 63±8.36 years and mean duration of diabetes mellitus for CA to develop was 18.01±8.23 years. 62.5% of the patients were male and 37.5% female. Bilateral presentation of CA was observed in 20.8% patients. Multiple sites of the foot were affected in 48.6% patients and belonged to type 4 classification of Brodsky. 

Conclusion: 
A high prevalence of CA was observed in the present study conducted on T2DMPN patients. In the majority of patients, the area of foot affected belonged to type 4 classification of Brodsky.
