“…Restoring a high native femoral offset, unfortunately, has the downside of increasing the varus and the rotational torque. Cantin et al 36. compared the fixation and survival of 280 lateralized stems to 527 standard Corail ® cementless stems over an average of 2-year followup.…”

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.

“…We speculate that undersizing the stem in relation to the length of the moment arm may also have contributed to failure. In a comparison of standard and lateralized versions of the Corail stem, Cantin et al noted an incidence of failure in 1.8% of offset stems versus 0% in standard stems [20]. He hypothesized that "lateralized stems are associated with high values of varus and torque moments, which may promote loosening" [20].…”

He hypothesized that "lateralized stems are associated with high values of varus and torque moments, which may promote loosening" [20]. We too speculate that this particular mechanical change to the moment arm may affect the stability of small stems in large males, although the NJR data did not differentiate between extended-offset and standard-offset Corail stems in their risk analysis.…”

Aseptic Loosening of Smaller Corail Stems in Heavy, Active Males: A Report of Three Cases

Recent concerns have been raised regarding a higher failure rate with smaller size Corail stems. This case series examines early aseptic loosening with smaller stems in three large male patients with Dorr A bone. Each stem was fluoroscopically aligned and sized until stable with axial and rotational stress. In each case, failure occurred within six months due to symptomatic metaphyseal debonding. Careful analysis suggests a correlation of failure to small size stems that are comparatively 1) undersized relative to the metaphysis, 2) undersized relative to patient body mass index, and 3) undersized relative to the amount of offset created.

“…The purpose of this study was to investigate, across a diverse cohort of femora (representative of a broad range of age, age, body mass and stature), the influence of restoring the femoral offset on the primary stability of cementless femoral stems, using a range of stem lateralisation options. For this study, the Corail® femoral stem (DePuy Synthes, Warsaw, USA) was selected as it is available with different offsets, with documented clinical history for all of the design options [17,18,[32][33][34][35]. Subject-specific FE modelling was used in this study to evaluate the primary stability of the different lateralisation options for the Corail® stem in a diverse cohort of femora for two of the most commonly encountered daily activities; level gait and stair climb activities.…”

“…A reduction in the femoral offset, achieved through stem medialisation by more than 5mm was found to reduce the abductor muscle forces by up to 16% [15,16]. However, short-to mid-term clinical studies found a slight decrease in survivorship of lateralised stems, compared the standard option [17,18], which raises concern. It has been suggested that this may be because lateralised stems tend to be subjected to high torsional loads, which may increase the risk of aseptic loosening of the implant [2].…”
