Clinical efficacy and finite element analysis of dynamic crossing screw system in the treatment of non-displaced femoral neck fractures in elderly patients with osteoporosis.

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
Controversy persists regarding the optimal fixation approach for non-displaced femoral neck fractures in elderly osteoporotic patients. While clinical experience with femoral neck system (FNS) is growing, biomechanical validation remains incomplete. This retrospective study included 80 elderly osteoporotic patients with non-displaced femoral neck fractures treated from 2019 to 2024 - 40 with FNS and 40 with CCS. We evaluated healing time, hip function, pain levels, and complications. Additionally, finite element models constructed from computed tomography (CT) scans of an elderly osteoporotic volunteer compared the biomechanical performance of both fixation methods in Garden I and II fracture patterns. FNS patients demonstrated faster healing and superior functional outcomes at 6 months. Complications including femoral neck shortening and fixation failure occurred less frequently with FNS. Finite element analysis revealed lower stress concentrations at the fracture site with FNS compared to CCS, indicating better mechanical stability. FNS showed advantages over conventional cannulated screws in this patient population, achieving faster healing, improved function, and reduced complications.
