The Functional Results of Ray Amputation

Abstract

Twenty patients (14 males, six females) were assessed at an average of 32 months (ten to 156 months) after ray amputation using the disability shoulder, arm, hand (DASH) questionnaire, physical examination and functional testing. There were 14 border (eight index, six little) and six central ray (five middle, one ring) amputations. Our results showed on average 27% less grip and 22% three-point pinch strength in the operated hands. Peak power output was 22% and average work output 14% less on the operated side than the contralateral hand. The DASH function score was 29.2 (range 3.3–74.2). Nine patients returned to their previous occupation, two had to change jobs and two did not return to work. Six patients were not working, one was of school age. The ensuing disability remained within limits reflected by our measurements and the acceptance of the patients.
