Proximal peri-implant femoral fractures occur following intramedullary nailing (IMN) fixation for trochanteric, femoral shaft, and distal femoral fractures. However, analyses of secondary hip fractures (SHFs) using large clinical samples are lacking. Therefore, we aimed to report the incidence and clinical outcomes of SHF after nailing fixation (IMN or cephalomedullary nailing [CMN]) for overall femoral fractures. In addition, we focused on IMN for femoral shaft fractures and investigated the risk factors for SHF. ⋯ In this multicenter study, the incidence of SHF after nail fixation for femoral fractures was 0.7%. The absence of femoral head fixation was significantly associated with SHF, and the clinical outcomes were poor. Therefore, femoral head fixation at the initial IMN fixation for femoral fractures may be a fixation option for surgeons to consider as an SHF prevention measure.

Multicenter Study
Pediatric severe traumatic brain injury mortality prediction determined with machine learning-based modeling.
Severe traumatic brain injury (sTBI) is a leading cause of mortality in children. As clinical prognostication is important in guiding optimal care and decision making, our goal was to create a highly discriminative sTBI outcome prediction model for mortality. ⋯ III; Prognostic.

Predictive factors for mortality after distal femoral fractures in the elderly: A retrospective multicenter (TRON group) study.
This retrospective multicenter study aimed to assess the 1-year mortality rate in elderly patients with distal femoral fractures (DFFs) and identify potential risk factors for mortality. ⋯ The 1-year mortality rate in elderly patients with DFFs was relatively low at 9.0%. Older age, lower BMI, and nursing home residency were associated with mortality after surgery for DFFs. Factors associated with the surgical procedure were not significant predictors.
