Predictors of Landry et al for Mortality After a Transmetatarsal Amputation (TMA)

Patient selection: transmetatarsal amputation

Outcome: mortality

Predictors of mortality:

(1) dialysis-dependent renal failure

(2) nonindependent living status

(3) need for preoperative revascularization

where:

• Living status was independent or nonindependent, but these were not defined.

Additional observations from the study:

(1) Healing could not be predicted based on demographic factors or the preoperative assessment.

(2) Patients who did not have healing usually had a below-the-knee amputation or died.

(3) 80% of patients were diabetics.

(4) Mean survival rate was 16.5 months for both those with and without healing.

(5) A patient who has poor rehabilitation prospects may be managed better by going directly to below-the-knee amputation.
