![]() Zhang Z, Qiu Y, Zhang Y, Zhu Y, Sun F, Liu J, Zhang T, Wen L (2022) Corrigendum: Global trends in intertrochanteric hip fracture research from 2001 to 2020: a bibliometric and visualized study. Our study revealed that FSIIN seemed to be superior to PFNA in the treatment of intertrochanteric fractures (OTA 31A1 + A2) due to less surgical damage and shorter fracture healing time. The finite element results show that the stress shielding effect of FSIIN is smaller. The incidences of post-operative anaemia, electrolyte imbalance, varus malalignment, and thigh pain were significantly lower in FSIIN than in PFNA groups (all p < 0.05). ![]() The operation time, fluoroscopy time, intra-operative blood loss, and length of incision were significantly decreased in the FSIIN group ( p 0.05). The distribution of all basic characteristics was similar between the two groups ( p > 0.05). Eventually, the 3D finite element model was established to analyze the stress of FSIIN and PFNA. At the last follow-up, the incidence of related complications in patients was calculated. Harris hip score (HHS) and visual analog scale (VAS) were used to evaluate the functional states. The intra-operative variables (operation time, fluoroscopy time, intra-operative blood loss, length of incision) and fracture healing time were compared between the two groups in this study. ![]() This study retrospectively analyzed a registered sample of 74 intertrochanteric fractures (OTA 31A1 + A2) surgically treated using FSIIN ( n = 36) or PFNA ( n = 38) from January 2015 to December 2021. This study was designed to compare clinical outcomes of the femoral stable interlocking intramedullary nail (FSIIN) with proximal femoral nail anti-rotation (PFNA) for the treatment of intertrochanteric fractures (OTA 31A1 + A2).
