Better practical evaluation for lower limb amputees

Abstract

Purpose: To avoid wastage of prostheses and unfair selection methods for prosthetic prescription, we aimed to develop a practical assessment tool for amputees with doubtful potential, using refurbished second hand modular prostheses. Methods: Thirty-seven primary amputees (33 transfemoral, 4 transtibial; 22 males, 15 females; median age 71 years, range 19 – 91) were considered to have doubtful potential for prosthetic use, due to single or multiple impairments. Amputees were assessed using custom-made socket and refurbished second-hand modular prostheses. Liability issues were fully covered. Results: Two patients died before completing the assessment. Median duration of assessment was 4 weeks (range 1 – 31 weeks). Among the 35 amputees who completed the trial, 14 (38%) proceeded to final prosthesis successfully and 21 (58%) decided to abandon the prostheses. The main reasons for prostheses rejection identified by the team were: hip flexion deformity (4); frailty (4); bilateral amputations (4); COAD (6), stroke (4), stump pain (3) and contralateral leg problems (2). Conclusions: High prosthetic rejection rate was expected and confirmed in this group (58%), but considerable number did proceed to definitive prosthesis. The method is practical and fair for amputees of doubtful potential, with considerable cost saving.
