Factores relacionados con el éxito en la protetización de amputados de extremidad inferior de etiología vascular

Abstract

ObjectiveRestoring the ambulation ability with prostheses in lower limb amputeesis essential to improve their functional independence. The aim of this study was to determine the factors involved in achieving prosthesis fitting in vascular amputees. Material and methodObservational longitudinal study of patients with major lower limb amputation of vascular etiology performed from April 1st 2017 to April 1st 2020. The following variables were compared between the group of patients who were prosthetized and those who were not: age, gender, body-mass index, comorbidity (Charlson index), independence in the activities of daily living (Barthel index) and ambulation ability (FAC test) before and a year after the amputation. The prosthetic use after a year was measured with the Houghton scale. ResultsA total of 80 patients were amputated with a mean age of 70.5 years old, 78.8% were male. The amputation level was supracondilealin 42 patients and infracondilealin 38 patients. The number of prosthetized patients was 35. The variables related to the possibility of prosthesis fitting were: younger age (P=0.020), less comorbidity (P=0.000), infracondileal amputation (P=0.024) and greater functional independence and ambulation ability prior to amputation (P=0.000). After a year 22 patients had died, only one of those who had been prosthetized. ConclusionsAlthough there are no clear recommendations to determine which amputees should be prosthetic fitting, in our patients the presence of fewer comorbidities and a good previous functional situation, younger age and infracondileal amputation, are related to greater success in achieving this objective.
