Abstract

BACKGROUND:: A well-fitting and comfortable ischial containment socket relies on accurately replicating the transverse plane angle of the ischium and ischial ramus angle, inside the medial socket brim. Prediction of the ischial ramus angle, may provide a way to determine the ischial ramus angle without in vivo measurement. OBJECTIVES:: To determine the accuracy with which the ischial ramus angle could be predicted and identify which variables contributed significantly to the prediction. STUDY DESIGN:: Cross-sectional study. METHODS:: Computed tomography scans were randomly sampled from a cadaveric database (n = 200). Standard multiple regression models were developed to predict the ischial r..
