Trans-metatarsal amputation in patients with a diabetic foot: reviewing 10 years experience.

Considerable disagreement exists whether trans-metatarsal amputations are indicated in persons with diabetes. A previous study reported that statistically the success rate of Syme's amputation in diabetic patients over 65 years of age resulted in a very poor results. The purpose of this study was to investigate the results of trans-metatarsal amputations, in patients with diabetes and to seek markers which could shed light upon the advantages/disadvantages of this procedure. The records of 46 patients covering a 10-year period (1996-2006) were used as a database. Twelve needed higher amputation level and another 10 needed a wound revision. All the patients that maintained the original amputation level walk without a need for a prosthesis and kept their previous abode. TMA in diabetic patients, although at a high risk for an extrasurgical procedure, once successful, the patient will regain his previous lifestyle.
