Gold wrist-assisted PFNA reduces internal complications and enhances recovery in obese osteoporotic patients with intertrochanteric femur fractures.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
introductionObese, osteoporotic patients with intertrochanteric fractures face higher surgical risks and delayed recovery. The "Gold Wrist," an auxiliary curved guiding instrument for proximal femoral nail anti-rotation (PFNA), was developed to assist guidewire placement and improve procedural efficiency.
methodsIn this retrospective cohort study, 500 patients (almost all with BMI > 28 and varying degrees of osteoporosis) underwent PFNA using either the Gold Wrist (n = 250) or conventional instruments (n = 250). Outcomes included operative time, fluoroscopy exposure, incision length, inflammatory markers, functional recovery, internal medicine complications, mechanical complications, hospitalization cost, and estimated carbon footprint. Finite element analysis assessed device mechanical stability.
resultsFinite element analysis confirmed reliable mechanical performance. The Gold Wrist group had shorter operative time (114.7 ± 34.6 vs. 127.3 ± 34.3 min), smaller incisions (6.15 ± 1.88 vs. 7.27 ± 1.79 cm), and lower TNF-α, IL-6, CRP, and CK levels (all P < 0.0001). Functional recovery was faster, with higher Harris Hip Scores (87.7 ± 2.7 vs. 84.7 ± 3.4) and greater hip motion. Internal medicine complications-including infection, deep vein thrombosis, pulmonary embolism, and cardiovascular events-were significantly reduced. Mechanical complications, including implant failure, were reported separately. Hospitalization costs and estimated carbon footprint were also lower.
conclusionThe auxiliary Gold Wrist device improves surgical precision, accelerates recovery, and reduces internal medicine complications in obese, osteoporotic patients undergoing PFNA. It offers a clinically effective and sustainable approach to managing high-risk intertrochanteric fractures.
