The History of Biomechanics in Total Hip Arthroplasty

Abstract

Biomechanics of the hip joint describes how the complex combination of osseous, ligamentous, and muscular structures transfers the weight of the body from the axial skeleton into the appendicular skeleton of the lower limbs. Throughout history, several biomechanical studies based on theoretical mathematics, in vitro, in vivo as well as in silico models have been successfully performed. The insights gained from these studies have improved our understanding of the development of mechanical hip pathologies such as osteoarthritis, hip fractures, and developmental dysplasia of the hip. The main treatment of end-stage degeneration of the hip is total hip arthroplasty (THA). The increasing number of patients undergoing this surgical procedure, as well as their demand for more than just pain relief and leading an active lifestyle, has challenged surgeons and implant manufacturers to deliver higher function as well as longevity with the prosthesis. The science of biomechanics has played and will continue to play a crucial and integral role in achieving these goals. The aim of this article, therefore, is to present to the readers the key concepts in biomechanics of the hip and their application to THA.

Statistical shape modeling of the hip and the association with hip osteoarthritis: a systematic review

“…The combination of a valgus hip with acetabular dysplasia 22,23 was associated with hip OA in two studies. From a biomechanical perspective, this could be explained by higher vertical joint reaction force 45 acting on a smaller surface during weight bearing. This combination has also been previously described 43 .…”

Anatomical variation of the Psoas Valley: a scoping review

“…However, the complexity of acetabular architecture and biomechanics may contribute to the limited progress of anatomical studies in this area [3,8], hence most health-care professionals do not have a comprehensive grasp on the psoas valley at present. Thus, this scoping review was conducted to systematically investigate the literature on the anatomy of the psoas valley and propose a unified definition of the anatomical structure, describe its dimensions, anatomical variations and clinical implications to eventually help manage our patients better.…”

Selective arterial embolization as neoadjuvant treatment in hip pseudotumors

“…Total hip arthroplasty (THA) is a common procedure in orthopedics; nevertheless, many complications are possible. [1][2][3] One of the most common delayed periprosthetic complications is pseudotumor (PT), which is a tumor-like granulomatous lesion or destructive cystic lesion that can develop near THA. [4,5] It is generally caused by prosthesis debris.…”
