ABSTRACT
OBJECTIVE: The objective of this study was to establish an
algorithm for surgical reconstruction of diabetic foot ulcers (DFUs).
STUDY DESIGN: Retrospective study
MATERIALS AND METHODS: In this series, 75 patients with
diabetic foot ulceration were treated at the Jawaharlal Nehru
Medical College from October 2008 to August 2013, and were
retrospectively reviewed. All patients in the study underwent
surgical reconstruction of the foot in the form of a skin graft, local
flaps, or free flaps, depending upon the characteristic of the
defect, general condition of the patient, and vascular status of the
limb. The medical notes of the patients were retrospectively
analyzed according to age, gender, ankle-brachial pressure index,
and comorbidities.
RESULTS: Twenty-eight patients (37%) underwent skin grafting,
39 (52%) underwent local pedicled flaps, and 8 (11%) underwent
free flap transfers. Sixty-eight patients (91%) achieved complete
healing, and amputation of the lower extremity could be avoided.
With the exception of 1 patient who experienced ulcer recurrence
within the following year and 6 patients in whom amputation of
the lower extremity was performed, all patients healed completely.
The mean hospital stay was 4.0 T 1 week.
CONCLUSIONS: From the results of this study, the authors
conclude that radical debridement and soft-tissue cover in the
form of a skin graft/flap is an effective method of managing DFUs.

INTRODUCTION
Diabetic foot ulceration is the most common complication seen in
the patient with diabetes.
1
The lifetime risk of a foot ulcer for
patients with diabetes may be as high as 25%,
2
and it is the most
critical risk factor for lower-extremity amputation.
3
Treatment of
diabetic foot ulcers (DFUs) requires management of a number of
systemic and local factors.
4Y7
The most common cause of hospitalization of patients with dia-
betes is soft-tissue and bone infections involving the foot.
8,9
The
main predisposing factors for the development of diabetic foot
infections are macroangiopathy, microangiopathy, peripheral neurop-
athy, and the altered immunologic response of patients with diabetes.
8,10
Presence of infection in the DFU is associated with substantial
morbidity and mortality.
11
Diabetic foot ulcers with infections
need to be detected at an early stage to avoid major limb ampu-
tations and prevent further complications. Wounds with infection
alter the normal healing process by disrupting the healing and
prolonging the inflammatory phase.
12
Many clinicians tend to treat the DFUs by conservative means
because of a lack of experience with care for patients with DFUs.
Although many patients with DFUs are hospitalized and treated
with conservative means, the role of surgical management in the
form of skin graft and flap is often underestimated, and DFUs can
lead to sepsis. Sepsis of the limb can become a life-threatening event
that may result in amputation of the lower extremity. It has been in-
vestigated by various researchers
13Y15
that sepsis increases the patients’
risk for above-ankle amputation, as well as increases the burden of
cost, as these patients are subjected to prolonged conservative ther-
apy. Early aggressive surgical intervention may prevent eventual
limb loss and the need for above-ankle amputation, decrease the total
cost to treat the patient, and may restore full ambulation earlier.
15
In other studies,
16
any amputation, regardless of the level, was
considered a treatment failure. Because limited amputation may
restore the ability to function, the authors consider debridement
and limited amputation to be part of the therapy. The authors use
the end point of above-ankle amputation to describe treatment
failure, as past studies have also done.
15
In this study, the authors reviewed their experiences with DFUs
and established an algorithm for surgical reconstruction of DFUs.
MATERIALS AND METHODS
In this study, a total of 75 patients with DFUs undergoing surgical
management from October 2008 to August 2013 were included
and retrospectively analyzed. The potential risk factors for healing
were documented from each patient’s medical record, including
