Functional and Radiological Outcomes of Proximal Femoral Nailing in Unstable Peritrochanteric Fractures: A Prospective Observational Study.
Article in Journal of orthopaedic case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Unstable peritrochanteric fractures of the femur are among the most challenging injuries in orthopaedic trauma, especially in the elderly with osteoporotic bone. The proximal femoral nail (PFN), a cephalomedullary device, offers potential biomechanical and clinical advantages. Objectives: To assess (1) the functional outcome of PFN in unstable peritrochanteric femoral fractures using the Harris hip score (HHS); (2) the radiological outcome using the radiographic union score for hip (RUSH); and (3) complications associated with PFN fixation. Materials and Methods: A prospective observational study was conducted at the Department of Orthopaedics, Gajra Raja Medical College and J.A. Group of Hospitals, Gwalior (M.P.), from September 2022 to June 2024. A total of 74 patients with unstable peritrochanteric fractures (Arbeitsgemeinschaft für osteosynthesefragen [AO] 31A2.2-A3.3) were operated on using PFN. Functional outcome (HHS) and radiological outcome (RUSH) were evaluated at 6 weeks, 3 months, and 6 months postoperatively. Statistical analysis was performed using Statistical Package for the Social Sciences v26 with paired t-tests, considering P < 0.05 significant. Results: The mean patient age was 54.3 ± 10.7 years; 67.5% were males. The most common fracture pattern was AO 31-A2.2 (40.5%). The mean operative time was 67.5 ± 11.1 min. Mean HHS improved significantly from 57.8 ± 8.9 at 6 weeks to 72.2 ± 4.7 at 3 months and 85.7 ± 6.2 at 6 months (P < 0.001). Radiological union (RUSH >18) was seen in 6.7% at 6 weeks, 54.1% at 3 months, and 98.6% at 6 months. Complications included superficial infection (4.05%), screw back-out (1.3%), reverse Z-effect (1.3%), and non-union (1.3%). Conclusion: PFN provides stable fixation, early rehabilitation, and high union rates in unstable peritrochanteric fractures. Its minimal soft-tissue dissection and superior biomechanical profile make it a preferred implant, especially in osteoporotic bone.
