Retrospective analysis reveals improved clinical efficacy in elderly patients with osteoporosis, suggesting enhanced healing and fewer complications.

Patients demonstrated improved hip function and faster healing with dynamic crossing screw system at 6 months, reducing complications.
FNS patients reported fewer complications, such as femoral neck shortening and fixation failure compared to conventional screws used.
This retrospective study evaluated clinical outcomes and finite element analysis using CT scans for biomechanical performance in elderly fractures.
Finite element analysis indicates that FNS provides better mechanical stability at the fracture site, supporting its use in clinical practice.

Sheng et al. (2025) studied this question.
