“…The Matlab (version 2014b, Mathworks, USA) script used to automate the implant sizing and alignment predicted a median size that match previous reports (size 12 for standard offset Corail ® and size 11 for lateralised counter designs) in a retrospective study on 172 stems [18]. The micromotion values predicted in this study were also in agreement with those reported in previous in-silico literature on cementless implant primary stability (Peak = 20 -356 μm) [25][26][27][43][44][45][46][47].…”

“…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].…”

“…One question that may arise is whether lateralised stems could be used during BHA due to femoral neck fracture and what the survival of high offset Reumatologia 2022; 60/5 stems would be in such patients. Some studies analysing the survivorship of high offset stems suggest that lateralized stems have shorter survival periods than standard stems [18,19] or that high offset stems have a high risk of loosening and surgery failure [20].…”

Introduction: Femoral neck fracture is one of the most common orthopaedic traumas affecting the elderly population. The standard treatment method is hip hemiarthroplasty and total hip arthroplasty. In hip hemiprostheses surgeons mainly have to reconstruct the femoral offset and limbs' length to obtain the correct gait biomechanics and a satisfactory surgical outcome. The aim of this study is to examine the radiological results of patients after hip hemiarthroplasty for femoral neck fracture and to evaluate the reconstruction of the femoral offset using standard neck angle stems. Material and methods: A consecutive series of 97 patients diagnosed with femoral neck fracture treated with a hip hemiprosthesis between 2017 and 2021 was identified and met the inclusion criteria. On preoperative images, the neck-shaft angle and the femoral offset on the healthy limb were measured. The femoral offset of the operated limb was measured on the postoperative X-rays. Results: There was a significant positive moderate correlation between neck-shaft angle and femoral offset change (r = 0.568, p < 0.0001). There was a statistically significant difference between femoral offset change and neck-shaft angle (24:52 vs. 14:7, p = 0.005). This means that in patients with coxa vara the change in femoral offset was more often < -5 mm. Less than half of operated patients had the femoral offset restored within a safe range (between -5 and 5 mm). Conclusions: Our study proved that it is sometimes hard to achieve femoral offset within a safe range while performing hip hemiarthroplasty in patients with coxa vara. The topic of using high offset stems in partial hip arthroplasty has not been thoroughly researched worldwide. However, taking into account the results of our study, during a hip hemiarthroplasty the usage of high offset stems for varus hips should be considered in order to improve the clinical outcome and improve patients' quality of life and functioning.

The aim of this study was to assess the clinical outcomes and survivorships of cementless Corail small stems to mid-size stems at a mid-term follow-up. A retrospective case-control study included 420 primary hip arthroplasties performed between 2006 and 2010. A case group of small size stems (8 to 10, n=173) were compared to a control group (mid-size stem 11 to 13, n=247). Complications and revisions were recorded. Kaplan-Meier survivorships were measured. Mean follow-up was 6 ± 1.1 years (range, 4-9). The mean PMA score and complication rate at last follow-up were not significantly different between cases and controls. No significative difference was noted between the groups for survivorship free of stem aseptic loosening (p=0.2), free of stem removal for any reason (p=0.09), and free of stem or cup revision for any reason (p=0.3). Small Corail stems were not associated with higher complication or revision rates compared to mid-size stems.
