The modified Pirogoff's amputation in treating diabetic foot infections: surgical technique and case series.
BACKGROUND
This paper describes the surgical technique of a modified Pirogoff's amputation performed by the senior author and reports the results of this operation in a single surgeon case series for patients with diabetic foot infections.


METHODS
Six patients with diabetic foot infections were operated on by the National University Hospital (NUH) diabetic foot team in Singapore between November 2011 and January 2012. All patients underwent a modified Pirogoff's amputation for diabetic foot infections. Inclusion criteria included the presence of a palpable posterior tibial pulse, ankle brachial index (ABI) of more than 0.7, and distal infections not extending proximally beyond the midfoot level. Clinical parameters such as presence of pulses and ABI were recorded. Preoperative blood tests performed included a glycated hemoglobin level, hemoglobin, total white blood cell count, C-reactive protein, erythrocyte sedimentation rate, albumin, and creatinine levels. All patients were subjected to 14 sessions of hyperbaric oxygen therapy postoperatively and were followed up for a minimum of 10 months.


RESULTS
All six patients had good wound healing. Tibio-calcaneal arthrodesis of the stump was achieved in all cases by 6 months postoperatively. All patients were able to walk with the prosthesis.


CONCLUSIONS
The modified Pirogoff's amputation has been found to show good results in carefully selected patients with diabetic foot infections. The selection criteria included a palpable posterior tibial pulse, distal infections not extending proximally beyond the midfoot level, ABI of more than 0.7, hemoglobin level of more than 10 g/dL, and serum albumin level of more than 30 g/L.
