Finite element analysis of different cephalomedullary nail treatments for basicervical femoral neck fracture.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cephalomedullary nail (CMN) is an ideal internal implant for the treatment of Basicervical femoral neck fracture (BFNF). This study uses finite element analysis techniques to compare the biomechanical characteristics of three types of CMN systems, namely proximal femoral nail antirotation (PFNA) InterTAN and proximal femur bionic nail (PFBN), in fixing BFNF using three cannulated screws (CSs) as controls, and analyzed their clinical significance. Based on femoral CT and internal implant data, a finite element analysis model for BFNF internal fixation was established: CSs, PFNA, InterTAN, and PFBN. The three types of loads, namely one-legged stance, torsion the femoral head, and walking, were simulated based on reference literature to obtain extreme values and cloud maps of data, including stress on fracture fragments and internal fixation devices, pressure between fracture surfaces, separation displacement, and sliding displacement. The biomechanical characteristics of different internal fixation devices were compared and analyzed. The finite element analysis data showed that in the one-legged stance group, the stress between the InterTAN fracture block and the internal fixation device, the extreme value of the pressure and sliding displacement between the fracture surfaces were lower than those of the other three models; In the femoral head torsion group, InterTAN had lower extreme values for both femoral head torsion displacement and fracture surface sliding displacement. The extreme values of separation displacement are second only to PFBN. In the walking exercise group, the extreme values of all indicators in InterTAN were lower than those in other models. Compared with PFNA and PFBN, InterTAN has better anti rotation ability and anti-inversion deformity ability, can provide better stability and safety, and provide guarantees for early functional exercise. This study provides clinical reference significance for the use of InterTAN in the treatment of BFNF.
