Clinical outcomes and revision strategies following failed internal fixation of peri-trochanteric femoral fractures: a retrospective cohort study.

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: Revision surgery for femoral peri-trochanteric fractures is a complex and high-risk intervention. This study aimed to systematically examine the multifaceted etiologies of primary internal fixation failures, classify them into distinct categories, and develop tailored revision strategies to enhance overall management and optimize clinical outcomes in peri-trochanteric fracture cases. Methods: We conducted a retrospective study of 141 peri-trochanteric fractures with failed internal fixation surgery between 2013 and 2023. The cohort comprised 87 males and 54 females, with a mean age of 60.34 ± 16.02 years. Of these, 96 were intertrochanteric fractures classified by the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association (AO/OTA) system (28 type A1, 20 type A2, and 48 type A3), and 45 were subtrochanteric fractures classified by the Seinheimer system. We conducted an in-depth analysis of failure mechanisms and subsequently categorized the patients into four groups, each with distinct revision procedures. Results: The average follow-up time was 15.96 ± 5.61 months. The joint replacement group had a significantly higher mean age (72.13 ± 13.00 years) than the revision internal fixation group ( Conclusions: We classified peri-trochanteric fracture surgical failures into four distinct categories based on age, presence of infection, integrity of the femoral head and acetabulum, varus deformity, and implant condition. We developed detailed diagnostic and treatment protocols for each category. Adhering to our established protocols, the imaging results and functional scores of all patients were consistently favorable. Our comprehensive treatment strategy can serve as a critical reference for standard revision procedures in the management of peri-trochanteric fractures.
