Purpose This study aimed to investigate the influence of proximal femoral anatomical parameters on coronal varus alignment of cementless femoral stems in total hip arthroplasty (THA) and to determine predictive thresholds. Methods A retrospective analysis of 315 primary THA cases (2022–2024) receiving a cementless stem (Polarstem) via an anterolateral approach was conducted. Preoperative pelvic radiographs were used to measure...

Conventional wisdom about mesoscale eddies is that cyclonic (anticyclonic) eddies are commonly associated with cold(warm) surface cores. Nevertheless, plenties of surface warm cyclonic eddies (WCEs) and cold anticyclonic eddies (CAEs) in the North Pacific Subtropical Countercurrent (STCC) region are observed by a synergistic investigation based on data from satellite altimetry, microwave radiometer, and Argo float profiles in...

Mesoscale eddies are omnipresent and play an important role in regulating Earth’s climate and ocean circulation in the global ocean. Here using the combination of satellite altimetry products and Argo float profile data, two types of abnormal eddies are investigated: WCEs(warm cyclonic eddies) and CAEs(cold anticyclonic eddies) with different cores than conventional eddies in the Japan/East Sea. By applying a classification me...
