Background And Objective: Proximal femoral osteotomy (PFO) is a surgical intervention, typically performed on paediatric population, that aims to correct femoral deformities caused by different pathologies (e.g., slipped capital femoral epiphysis).
View Article and Find Full Text PDFProximal femoral osteotomy (PFO) is a frequently performed surgical procedure to correct hip deformities in the paediatric population. The optimal size of the blade plate implant in PFO is a critical but underexplored factor influencing biomechanical outcomes. This study introduces a novel approach to refine implant selection by integrating personalized neuromusculoskeletal modelling with finite element analysis.

- Finite element analysis (FEA) is a widely used technique in orthopaedic research to measure stress and strain in bones, specifically in this study focusing on the femur.
- The research compared outcomes like femoral head deflection and mechanical stress under four common boundary conditions against a gold standard method, revealing that traditional methods often led to unrealistic biomechanical results.
- A new biomechanical constraint method demonstrated better accuracy in reflecting real-life femur biomechanics, showing results consistent with physiological data and outpacing traditional methods for both normal and pathological femurs.
Article Synopsis
- This study investigates how the printing orientation of zirconia crowns affects their accuracy and surface roughness.
- Twelve additively manufactured crowns were printed at three different orientations and compared to twelve milled crowns using advanced measurement techniques.
- Results show that the 45° orientation using an industrial printer has the best trueness compared to milled crowns, and all printing methods produce marginal regions with acceptable roughness for clinical use.
Objectives: There is a need for diagnostic devices that can assist prosthetic care providers to better assess and maintain residuum health of individuals suffering from neuromusculoskeletal dysfunctions associated with limb loss. This paper outlines the trends, opportunities, and challenges that will facilitate the development of next-generation diagnostic devices.
Design: Narrative literature review.
