Zusammenfassung: | •A diabetic trans-metatarsal amputation is an effective limb salvage option, with a low reoperation rate.•The outcome is less favourable in patients with peripheral vascular disease.•A well healed trans-metatarsal amputation stump provides independent mobility in the majority of patients.
This retrospective case series reports the reoperation rate, survival rate and mobility status in patients with diabetes mellitus who had undergone a trans-metatarsal amputation (TMA) managed within a diabetic foot care service.
Forty-one consecutive patients (37 men, 4 women) underwent a TMA with primary wound closure between January 2008 and December 2017. Eighty-eight per cent (36/41) of the patients were followed-up for a mean of 2.3 years. The outcomes were retrospectively reviewed.
Four (11%) of the 36 patients required reoperation, including three (8%) major amputations. All of the patients requiring a reoperation had peripheral vascular disease. Eleven patients died giving a four-year survival rate of 69% (25/36). Of the surviving patients who had not required revision to a major amputation 96% (21/22) were fully mobile in bespoke orthoses. A third used a walking cane.
This study shows that a TMA with primary wound closure in patients with diabetes mellitus, is effective for limb salvage with low reoperation and major amputation rates. A well healed TMA stump provides independent mobility in the majority of patients. The failures occurred in patients with peripheral vascular disease who, even after percutaneous trans-luminal angioplasty, had a 19% major amputation rate.
