Abstract
BackgroundCharcot osteoarthropathy or charcot foot is a rare, chronic, non-communicable condition of bones and joints which may results into severe deformity and more prone to develop ulcers possibly leading to amputation. The purpose of this study was to determine the prevalence of Charcot osteoarthropathy and its association with age, BMI, gender, duration of diabetes, HBA1c and peripheral neuropathy.MethodsA total of 1931 subjects with type 2 diabetes having mean age 50.72 ± 10.66 years presenting in a specialist diabetes clinic at shalamar hospital, Lahore, Pakistan were enrolled. The diagnosis of Charcot osteoarthropathy was made by examination of both dorsal and plantar surfaces of foot for swelling, erythema, increase in temperature and any musculoskeletal deformity which was later confirmed by radiographs. Assessment of neuropathy was carried out by checking the sense of pressure, joint position and vibration. BMI (Body Mass Index), fasting blood glucose (FBG) and HbA1C were determined.ResultsIn all subjects including male 704 (36.45 %) and female 1227 (63.55 %), 0.4 % subjects had charcot deformity, while 0.2 %, 0.15 % and 0.05 % subjects having right, left and bilateral deformity respectively. Bilaterally symmetrical neuropathy was diagnosed in 25.4 % in subjects. There was a significant association (p < 0.05) of deformity with duration of diabetes, HbA1C and neuropathy, however no significant association (p > 0.05) was found with age, BMI, weight, height and gender.ConclusionThere is a need to have a special care of persons with diabetes regarding blood glucose control and development of peripheral neuropathy. Early identification and management of risk factors may prevent the occurrence of charcot deformity. Patients must be educated about the foot care.

Diabetes is a chronic condition associated with the number of complications such as peripheral artery disease, foot ulcerations, peripheral neuropathy and charcot osteoarthropathy
The classic deformity associated with Charcot foot is “rocker bottom deformity” which is a collapse of Younis et al BMC Endocrine Disorders (2015) 15:28 midfoot [6]
Summary
Charcot osteoarthropathy or charcot foot is a rare, chronic, non-communicable condition of bones and joints which may results into severe deformity and more prone to develop ulcers possibly leading to amputation. Diabetes is a chronic condition associated with the number of complications such as peripheral artery disease, foot ulcerations, peripheral neuropathy and charcot osteoarthropathy. These complications are expected to increase in the prevalence [1] as the worldwide prevalence of diabetes for all age groups is expected to be 4.4 % by 2030 which was approximately 2.8 % in the year 2000 [2]. Charcot foot was first described in 1883, and it was associated to diabetes mellitus in 1936 [4] It is a chronic progressive noncommunicable disease of the joints and bones which may involve single or multiple bones or joints. The prevalence of Charcot osteoarthropathy is reported to be 0.08 % to 13 % in individual with diabetes and high risk patients respectively [7]
