Abstract:
INTRODUCTION:Syme amputation has been shown to have value in patients with diabetic foot infections, but it has inherent drawbacks. A potential alternative is the modified Pirogoff amputation. Our objective was to evaluate the outcome of modified Pirogoff amputation using internal fixation with 6.5-mm cannulated screws in the management of diabetic foot.
METHODS:This is a prospective study of 13 patients admitted from January 2012 to June 2015. Inclusion criteria were infection limited to the forefoot, presence of a palpable posterior tibial pulse and an ankle-brachial index of more than 0.7. Internal fixation of the calcaneum to the tibial was performed using two 6.5-mm cannulated screws under image intensifier control.
RESULTS:In ten cases, the wounds were healed at three weeks. Osseous union was observed in ten cases; the time taken for its occurrence was 2-5 months. Removal of screws was performed in five cases. Five cases developed technical complications of screw tract infection, with two cases having distal screw migration. Good results, defined as cases not requiring a below-knee amputation for two years postoperatively, were obtained in 10 (77%) cases. At the three-year follow-up, three additional cases required proximal amputation, leaving 7 (54%) cases with good outcomes.
CONCLUSION:Our prospective study showed that with careful selection of patients, good postoperative results can be obtained. There is a definite role for modified Pirogoff amputation in the management of diabetic foot problems.
