摘要: Transtibial stump volume can change dramatically postoperatively and jeopardise prosthetic fitting. Differences between individuals make it hard to give general recommendations of when fit with a definitive prosthesis. Measuring the on every patient could solve this, but most methods for assessments are too complicated clinical use.The aim this study was evaluate accuracy intra- interrater precision method estimate from circumferential measurements. The approximates as number cut cones tip sphere segment.Accuracy evaluated theoretically six scanned models in CAPOD software manually models. Precision by comparing measurements made four CPOs eight stumps. devices were wooden rule metal circumference rule. errors estimated intraclass correlation coefficient (ICC), where 0,85 considered acceptable, criterion that error ±5% acceptable (5% corresponds one stocking).The accurate all theory only reality. ICC 0,95-1,00 intrarater 0,76 precision. Intra- unsatisfying using criteria. Variations heights circumferences causing errors.The needs be developed is not suitable stumps narrow ends. Using longer (about 30 cm) set square end assess recommended improve flexible measuring-tape (possible disinfect) spring-loaded handle
