Objective: Shelf acetabuloplasty is a type of joint-preserving surgery. There are only a few cases of studying the mechanical evaluations of shelf acetabuloplasty. The objective of this study was to investigate the biomechanical effects of acetabular dysplasia on the acetabular margin and the efficacy of shelf acetabuloplasty using a threedimensional musculoskeletal model and finite element analysis.
Methods: Subjects were five adult female patients with hip osteoarthritis and acetabular dysplasia who underwent the shelf procedure. Using the data of 4 healthy adult women, joint reaction force in the hip joint during static standing was estimated using Any Body Modeling System. From the CT images of each subject, finite element models of the pelvis and the right femur were constructed using Mimics and then converted to a three-dimensional finite.. View More»
