Outcomes of Wedge Wing in the Lag Screw for Unstable Intertrochanteric Fractures in Elderly Patients.
Article in Hip & pelvis, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo evaluate clinical-functional and radiologic outcomes of elderly patients with an unstable intertrochanteric femur fracture treated with a wedge wing in the lag screw. MATERIALS AND
methodsForty-eight patients treated with the Dyna Locking Trochanteric nail (DLT nail) to resolve an unstable intertrochanteric femur fracture were reviewed retrospectively. Based on AO/OTA classification, Fracture 31-A2 (34 cases) and 31-A3 (14 cases) were included in the analysis. We measured the femoral neck-shaft angle, tip-apex distance (TAD), Cleveland index, sliding distance of the lag screw, and time to the fracture union. The Harris Hip Score and Paker and Palmer's mobility score for clinical evaluation were used.
resultsThe mean follow-up period was 21.4 months (range, 12-34 months). The postoperative state of reduction was good in 28 cases and acceptable in 20 cases. The mean TAD was 20.5 mm. The position of the lag screw was center-center in 30 cases and center-inferior in 18 cases. The mean sliding distance of the lag screw was 3.4 mm at the last follow-up. The mean union time was 4.5 months. Two cases had complications which included a cut-out (1 case) and non-union (1 case). The mean Harris Hip Score was 86.5±8.3 (range, 76-90). Walking ability in 34 of the cases (70.8%) at last follow-up was similar to that prior to fracture.
conclusionFunctional and radiological outcomes are satisfactory using the DLT nail in the treatment of elderly patients with unstable intertrochanteric fractures; however, wedge wing in the lag screw does not prevent implant-related complications.
