Diabetes mellitus (DM) is one of the most important and common metabolic disorders affecting about 2-5% of the population in Europe and about 20% of the population in various other parts of the world. 
Diabetes Mellitus (DM) is one of the most widespread non communicable diseases across the world.
The incidence of diabetes mellitus is increasing worldwide; by 2030, it will grow up to 366 million. This estimation occurred because of longer life expectancy and changing habits of diet. 
Diabetes mellitus (DM) is one of the most important and common metabolic disorders affecting about 2-5% of the population in Europe and about 20% of the population in various other parts of the world. 
Even though there are many complications affecting the person with diabetes, none are more devastating than those complications involving the foot.  Two types of complications are encountered usually with DM: microvascular and macrovascular. Diabetic neuropathy is one of the most commonly-occurring microvascular complications, of which the most common type is distal symmetrical neuropathy or polyneuropathy. It is estimated that 15% of patients with diabetes will suffer from diabetic foot ulcer during their lifetime. 
The relationship between diabetic neuropathy, the insensitive foot, and foot ulceration was recognized by Pryce, a British surgeon, over a century ago. He stated that, "It was abundantly evident that the actual cause of the perforating ulcer was peripheral nerve degeneration and that diabetes itself played an active part in the causation of the perforating ulcer. 
Foot ulcers significantly contribute to morbidity and mortality of patients with diabetes mellitus. The diabetic patients with foot ulcers require long-term hospitalization and carry the risk of limb amputation.  Studies show that severity of diabetic foot ulcer is the strongest significant risk factor of amputation for diabetes patients. In developed countries, one in every six people with diabetes will have an ulcer during their lifetime. The risk is even higher in developing countries. 
In total, the most common pathway to develop foot problems in patients with diabetes is peripheral sensory motor and autonomic neuropathy that leads to high foot pressure, foot deformities, and gait instability, which increases the risks of developing ulcers.  Today, numerous investigations have shown that elevated plantar pressures are associated with foot ulceration.  Additionally, it has been demonstrated that foot deformities and gait instability increases plantar pressure, which can result in foot ulceration. 
Multiple risk factors associated with the development of DF.  These risk factors are as follows: gender (male), duration of diabetes longer than 10 years, advanced age of patients, high Body Mass Index, and other co-morbidities such as retinopathy, diabetic peripheral neuropathy, peripheral vascular disease, glycated haemoglobin level (HbA1C), foot deformity, high plantar pressure, infections, and inappropriate foot self-care habits.  The primary management goals for DF are to obtain wound closure as expeditiously as possible.  As diabetes is a multi-organ systemic disease, all co-morbidities that affect wound healing must be managed by a multidisciplinary team for optimal outcomes.
In India, it is estimated that approximately 40, 000 legs are being amputated every year, of which 75% are neuropathic with secondary infection, which is potentially preventable. Infection of the foot is the frequent complication of diabetes mellitus and affects 12% of patients with diabetes mellitus. By taking certain measures like regular inspection of foot daily for redness, swelling and other signs of injury, wearing appropriate shoes, cessation of smoking etc one can prevent the diabetic foot problem and its complications.
Hence this study has been undertaken to evaluate the various modes of clinical presentation of diabetic foot ulcer and to evaluate the outcome of various treatment strategies.
This is an observational study. A total of 50 clinically diagnosed cases of diabetic foot were studied over a period of 18 months in tertiary care hospital, central India. Institutional ethical committee approval was obtained to carry out this study. Informed consent was obtained from all the patients included in the study. In the present study we intended to study the signs, symptoms and complications of the disease and also management of diabetic foot. This study was conducted in tertiary care hospital, central India, which included total 50 cases of diabetic foot who presented in surgery OPD or emergency department and got admitted. Sample size was taken for convenience.
1. Any known diabetic patient with chronic foot and leg ulcers.
2. Any known diabetic patient with Cellulites, osteomyelitis, blisters, gangrene of lower limb.
3. Patients with all the above clinical presentations diagnosed as diabetic, after admission (Random blood sugar-more than 160 mg/dl, Fasting blood sugar-more than 100 mg/dl, 2 hrs. Postprandial-more than 140 mg/dl). 
Patient aged below 18 years.
The data were reported as mean [+ or -] SD and frequency. The data collected was entered into Microsoft excel spread sheet and analysed using IBM SPSS Statistics, Version 16.
Out of 50 patients studied, most of the diabetic patients were in the age group of 51-60 (44%). The youngest patient was of 35 years and the oldest was of 80 years.
In present study out of 50 patient 42 were male and 8 were females. It shows male predominance. 42(84%) were male patient and 8 (16%) cases were female.
In present study of the 50 cases, 56% presented with ulcer, 26% cellulitis, 10% presented with ulcer with gangrene and 8% with ulcer with cellulitis.
History of Trauma
In present study history of trauma (thorn prick, shoe bite, nail prick, wood piece prick etc. as a precipitating factor was present in 32 patients making a total of 64%.
Site of Lesion
Most common site of lesion was dorsum of foot accounting for 38% followed by toes accounting for 28%.
Duration of Diabetes Mellitus
In present study, 17 patients were detected as diabetes mellitus on admission and rest 33 patients were known case of diabetes. In 18 patients, duration of diabetes mellitus was between 1-5 years.
Incidence of Osteomyelitis
Osteomyelitis was seen in x-rays of 6 patients.
Incidence of Peripheral Neuropathy
Out of 50 patients, 22 patients with diabetic foot had peripheral neuropathy.
Incidence of Different Causative Organisms
The most common organism grown on culture of pus was Staphylococcus aureus in 28 (56%) patients followed by Pseudomonas in 6 patients (12 %), Proteus in 5 patients, E coli in 3 patients, Klebsiella in 4 patients. In 4 patients (8%) there was no growth.
Glycosylated Hb (HbA1c) Level
Out 50 patients, 33 patients accounting for 66% showed glycosylated Hb level less than 7 mg% and had better glucose control with shorter duration of hospital stay compared to 17 patients in whom glycosylated Hb were more than 7 mg% and had poor glucose control.
Duration of Hospital Stay
The average duration of hospital stay was 22 days with minimum days of stay of 5 days and the maximum days of stay being 90 days.
In present study, debridement was done in 32 patients, skin grafting after thorough debridement was done in 6 patients, and major amputation in 5 patients. Only dressings were done in 4 patients.
In the present study we have studied total 50 cases of diabetic foot. Most common age group who presented with diabetic foot in my study was between 51 - 60 years with an average of 56.4 years.
In Study of Reiber et al the highest percentage was in persons aged between 45 to 64 years.  In present study, 42 were male and 8 were female, out of 50, comprising of 84% males and 16% females.
In Manchester series study, 67.4% were male and 32.6% were female.  Male preponderance may be due to males are more exposed to injuries during their occupational and recreational activities that put more stress on the feet In my study majority of patients presented with Ulcer (56%), 26% with cellulitis, 10% with ulcer and gangrene and 8% with cellulitis with ulcer.
Description of the ulcer characteristics on presentation is essential for the mapping of the ulcer's progress during treatment. [19,20]
In the present study 64% of patients were presented with history of trauma. This was comparable to Reiber et al series in which 77% of patients had history of trauma. 
Out of 50 patients studied, most common site of lesion was dorsum of foot (38%) followed by toes (28%) and sole of foot (22%) of all cases.
As per Apelquist Study, toes were affected in 51%, sole was affected in 28% and dorsum in 14%. 
Out of 50 patients, 18 patients presented between 1-5 years and mean age is 2.5 years. 17 patients were detected diabetes mellitus on admission.
This shows that foot complications occurred early in our study most probably due to lack of strict glucose control.
In the present study 12% of the patients had osteomyelitis. In the x-ray. Demineralization, periosteal reaction and bony destruction are classic radiographic triad of osteomyelitis. It is comparable to Manchester series in which 20% had osteomyelitis and JOS university study, [18,22] in which 14% had osteomyelitis.
The incidence of peripheral neuropathy in present study is 44% that is out of 50 patient, 22 patients were having peripheral neuropathy. In Walter DP et al series, the incidence of peripheral neuropathy was 39.4%.
In the present study, pus discharge and swab from ulcer were sent for culture and antibiotic sensitivity testing.
Most common organism isolated was staphylococcus aureus in 28 patients out of 50, comprising of 56%.
Other organisms isolated were pseudomonas (12%), proteus (10%), Klebsiella (8%) and E. coli (6%). In 8% patients, there was no growth of any bacteria.
Infection is the 3rd most common factor responsible in the pathogenesis of diabetic foot lesion. In the present study only 33 patients had HbA1c level less than 7 mg% and they had shorter duration of hospital stay compared to the patients with HbA1c more than 7 mg%. In the present study, average duration of hospital stay was 22 days. The duration of hospital stay was related to control of blood sugar level and type, extent, severity of disease.
In present study, out of 50 patients, 32 patients underwent thorough debridement. STSG was done in 6 patients with good uptake of graft. STSG reduced the healing time in these patients and decreased their hospital stay.
Conservative treatment along with daily dressing was done in 4 patients having less infected ulcer. Disarticulation of toes in 3 patients was done. Amputation was done in 5 patients with complicated foot infection.
Patients with diabetes mellitus are often encountered with complications such as ulceration, infection, gangrene, cellulitis and lower extremity amputations. These complications frequently result in extensive morbidity, repeated hospitalizations and mortality. They take a tremendous toll on the patient's physical and mental well-being as well as impose a substantial economic burden, often removing the patient from the workforce and placing a financial drain on the health care system. Not all diabetic foot complications can be prevented, but it is possible to dramatically reduce their incidence through appropriate management and prevention programs. Such prevention programs can reduce the incidence of foot ulceration through modification of self-care practices, appropriate evaluation of risk factors, and formulation of treatment protocols aimed at early intervention, limb preservation, and prevention of new lesions.
