Abstract EN
Prosthetic impingement is important to consider during total hip arthroplasty planning to minimise the risk of joint instability.
Modelling impingement preoperatively can assist in defining the required component alignment for each individual.
We developed an analytical impingement model utilising a combination of mathematical calculations and an automated computational simulation to determine the risk of prosthetic impingement.
The model assesses cup inclination and anteversion angles that are associated with prosthetic impingement using patient-specific inputs, such as stem anteversion, planned implant types, and target Range of Motion (ROM).
The analysed results are presented as a range of cup inclination and anteversion angles over which a colour map indicates an impingement-free safe zone in green and impingement risk zones in red.
A validation of the model demonstrates accuracy within +/- 1.4° of cup inclination and anteversion.
The study further investigated the impact of changes in stem anteversion, femoral head size, and head offset on prosthetic impingement, as an example of the application of the model.
