OBJECTIVE: compare risk of all-cause and cardiovascular disease
(CVD) mortality in people with a lower-extremity amputation (LEA)
attributable to diabetes and people without an LEA.
RESEARCH DESIGN AND METHODS: study of CVD and its risk
factors in 13 American-Indian communities. LEA was ascertained at
baseline by direct examination of the legs and feet. Mortality
surveillance is complete through 2000.
RESULTS: 2,108 participants with diabetes
134 participants (6.4%) had an LEA.
Abnormal ankle-brachial index (53%), albuminuria (87%),

8. Diabetes Duration
Diabetic participants without LEA- 11.9 years
Toe amputation -18.6years
Below-the-knee amputations -21.1 years
Diabetic subjects with LEA - 19.8 years
During 8.7 (+/-2.9) years of follow-up
102 of the participants with LEA (76%) died from all causes
35 (26%) died from CVD
1,974 diabetic participants without LEA at baseline,
604 (31%) died from all causes and 206 (10%) died from CVD.
CONCLUSIONS: LEA is a potent predictor of all-cause and
CVD mortality in diabetic American Indians.

J Bone Joint Surg Am. 2003 Sep;85-A(9):1667-72J Bone Joint Surg Am. 2003 Sep;85-A(9):1667-72METHODS: Ninety-seven adult patients with diabetes mellitus who
underwent Syme ankle disarticulation because of a neuropathic foot
with an infection or gangrene, or both, during an eleven-year period
were studied retrospectively
RESULTS: Eighty-two patients (84.5%) achieved wound-healing. At a
minimum follow-up of two years, all but two patients were able to walk
with a prosthesis. Thirty of the ninety-seven patients died at an average
of 57.1 months following surgery.
CONCLUSIONS:. This function-sparing amputation can be
successfully performed with a reasonable risk. Patients managed with a
Syme ankle disarticulation appeared to remain able to walk better and to
survive longer than similar patients who had a transtibial amputation
and served as historical controls.

Study concludes that mobility rates one year after
prosthetic provision for unilateral trans-tibial and
trans-femoral amputees worsen with increasing
age at amputation and a higher level of
amputation.
