Effect of a distal weight-bearing implant on visual analog scale scores in 23 transfemoral amputees.

The objective of this interrupted time series clinical trial was to evaluate the effect of a distal weight-bearing implant on well-being in patients with transfemoral amputations using the visual analog scale (VAS). A total of 29 patients from five hospitals with previous transfemoral amputations were surgically implanted with an osseoanchored implant with a distal spacer that allows a direct load on the residuum over the distal surface of the socket. Patients were followed for a 14-month period and assessed presurgically and postsurgically using the VAS. The Wilcoxon test was used to evaluate the differences between variables. VAS mean scores improved significantly after intervention. Sign…
