Case Report: Proximal femoral valgus osteotomy and dynamic hip screw fixation for post-traumatic coxa vara secondary to femoral neck or intertrochanteric fracture nonunion or malunion: a retrospective case series.

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
Background: Post-traumatic coxa vara following femoral neck or intertrochanteric fracture nonunion or malunion remains a difficult problem in young and middle-aged patients, in whom salvage total hip arthroplasty carries excess complication risk. Proximal femoral valgus osteotomy is a joint-preserving alternative, but evidence supporting fixation with a dynamic hip screw (DHS) is limited, and is largely confined to younger cohorts. Case summary: We report a single-center, retrospective, consecutive case series of twelve patients (seven men, five women; mean age 52.2 ± 20.0 years, range 20-73) treated between January 2020 and December 2024. Etiologies included failed internal fixation of intertrochanteric fracture ( Outcomes: Bony union was achieved in all twelve patients at a mean of 19.1 ± 4.1 weeks. The mean neck-shaft angle improved from 100.3° to 132.2°, the mean Harris Hip Score from 50.4 to 80.2, and the mean limb shortening reduced from 2.4 cm to 0.7 cm (all Conclusion: Proximal femoral valgus osteotomy with DHS-based fixation reliably restores hip mechanics, achieves union, and produces meaningful functional improvement in post-traumatic coxa vara, including in selected older patients with a viable femoral head.
