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 ramus angle based on pelvic measures. Results: The regression model explained 10.5% of the variance in ischial ramus angle (p = 0.018). The standard error of the estimate was 11.32°. While regression models by sex explained a larger proportion of the variance, the resulting accuracy was not improved. Conclusion: The regression models explained a small proportion of variance in ischial ramus angle. The average error associated with the prediction was too large to accurately predict the ischial ramus angle for use in clinical practice. Contrary to commonly held beliefs, there was no statistically significant difference in ischial ramus angle between sexes. Clinical relevance Prediction of ischial ramus angle does not have sufficient accuracy to be clinically useful, but descriptive data may help clinicians identify casting errors and correct these in a plaster positive, knowing that the average ischial ramus angle was 32.65°±5.59° (relative to mid-sagittal plane) and does not vary between sexes. authors Quigley, Matthew Dillon, Michael P Fernandez, Richard GD Erbas, Bircan Briggs, Chris status published publication date 2019 has subject area Adult (MeSH) Age Factors (MeSH) Amputation (MeSH) Amputation Stumps (MeSH) Artificial Limbs (MeSH) Biomechanical Phenomena (MeSH) Cross-Sectional Studies (MeSH) Female (MeSH) Femur (MeSH) Gait (MeSH) Hip Joint (MeSH) Humans (MeSH) Imaging, Three-Dimensional (MeSH) Ischium (MeSH) Male (MeSH) Middle Aged (MeSH) Multivariate Analysis (MeSH) Prosthesis Design (MeSH) Prosthesis Fitting (MeSH) Regression Analysis (MeSH) Rehabilitation (Science Metrix) Risk Assessment (MeSH) Sex Factors (MeSH) published in Prosthetics and Orthotics International Journal Research keywords Amputation GROWTH Life Sciences & Biomedicine Orthopedics Rehabilitation SEX Science & Technology anthropometry computed tomography ischial containment ischial ramal angle pelvic morphology prediction prosthesis socket transfemoral Identity Digital Object Identifier (DOI) 10.1177/0309364618789439 PubMed ID 30044195 Additional Document Info Publisher International Society for Prosthetics and Orthotics start page 39 end page 46 volume 43 issue 1 La Trobe University Scholars © Copyright 2021 La Trobe University Scholars.
