Selective criteria for successful long-term prosthetic use.

M J Mueller, A Delitto

Physical Therapy

|July 1, 1985

Summary

Elderly patients with below-knee amputations (BKAs) are significantly more successful long-term prosthetic users than those with above-knee amputations (AKAs). Compliance and post-prescription medical issues impact AKA success.

Background:

Vascular disease is a common cause of amputation in the elderly.
Long-term prosthetic use is crucial for maintaining mobility and quality of life in amputees.
Identifying predictors of successful prosthetic use is essential for effective rehabilitation.

Purpose of the Study:

To determine factors associated with successful long-term prosthetic use in elderly patients with vascular disease-related amputations.
To compare prosthetic success rates between below-knee amputations (BKAs) and above-knee amputations (AKAs).

Main Methods:

A telephone survey was conducted with elderly patients who had amputations secondary to vascular disease between 1977 and 1982.
Success was defined as wearing the prosthesis at least part of every day.
Statistical analysis, including chi-square tests, was used to compare success rates and identify contributing criteria.

Main Results:

Below-knee amputees (BKAs) demonstrated significantly higher success rates (37/38) compared to above-knee amputees (AKAs) (7/18).
For AKAs, only compliance and post-prescription medical problems significantly differed between successful and unsuccessful long-term users.
BKAs had a success rate of over 97%, while AKAs had a success rate of approximately 39%.

Conclusions:

Below-knee amputation (BKA) patients are considerably more likely to achieve successful long-term prosthetic use than above-knee amputation (AKA) patients.
Physical therapists can use these findings to set realistic expectations for geriatric amputees.
Compliance and managing medical issues post-prescription are critical for successful long-term prosthetic use in above-knee amputees (AKAs).
