Modelling Techniques

Evaluation and prediction of wear play a key role in product design and material selection of total hip replacements, because wear debris is one of the main causes of loosening and failure. Multifactorial clinical or laboratory studies are high cost and require unfeasible timeframes for implant development. Simulation using finite element methods is an efficient and inexpensive alternative to predict wear and pre-screen various parameters. This article presents a comprehensive literature review of the state-of-the-art finite element modelling techniques that have been applied to evaluate wear in polyethylene hip replacement components. A number of knowledge gaps are identified including the need to develop appropriate wear coefficients and the analysis of daily living activities.

Total hip replacement (THR) has been one of the main choices in treating dysplasia and other disabling conditions of the coxofemoral joint of large-breed dogs. Quantitative data of the three-dimensional (3D) morphology of the native normal acetabulum will be helpful for better design and implantation of prosthetic components. However, 3D orientation and morphological parameters of the native acetabulum in large-breed dogs are rarely reported. The purposes of the study were to measure the values of the 3D morphological parameters of the native acetabulum in Labrador Retriever dogs, namely acetabular orientation in relation to the pelvis, as well as the radius, angle between ventral and dorsal rims, and the distance from the center to the dorsal rim of the acetabulum using a 3D CT-derived model. The data will be useful for developing a more accurate guideline for improving current THR designs and for more accurate placement of the acetabulum component during THR surgery.

Abstract Total hip replacements have been performed in the UK since the 1960s, with over 280000 primary hip replacements being conducted between January 2017 – December 2019. The formation of pseudotumours is an uncommon and an unusual long-term complication of total hip replacements. Formed by galvanic corrosion of the metal prosthesis, patients can display an array of symptoms. We herein report a rare presentation of unilateral leg oedema in an elderly female, mimicking deep vein thrombosis. Despite normal metal ion levels, radiological investigations revealed an irregular cystic mass extending into the iliac fossa compressing the neurovascular bundle in the groin. The patient underwent complex revision hip surgery with dual mobility hip replacement and an Exeter stem with excision of the pseudotumour. This case highlights the importance of appropriate workup for these patients and the involvement of a multidisciplinary team.
