High incidence of stem loosening in association with periprosthetic femur fractures in previously well-fixed cementless grit-blasted tapered-wedge stems.
Article in International orthopaedics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
purposePeriprosthetic femur fracture is a potentially worrisome phenomenon for cementless stem fixation. The aim of this study was to document the incidence of stem loosening following periprosthetic femur fracture in previously well-fixed cementless grit-blasted tapered-wedge stems.
methodsWe identified 36 periprosthetic femur fractures of either Vancouver B1 or B2 following hip arthroplasties using cementless grit-blasted tapered-wedge titanium stems at three participating institutions (GB group). The control group consisted of 21 periprosthetic femur fractures of either Vancouver B1 or B2 following hip arthroplasties using cementless proximal porous-coated stems at the same institutions during the same period of study (PC group). All femoral stems had been in a well-fixed state before occurrence of fracture. All patients were treated surgically and femoral stem stability was assessed using preoperative radiographs and confirmed by intraoperative scrutinization.
resultsSeven (19.4%) of 36 fractures were Vancouver B1 and 29 (80.6%) were Vancouver B2 in the GB group, whereas 18 (85.7%) of 21 fractures were Vancouver B1 and 3 (14.3%) were Vancouver B2 in the PC group (P < 0.0001). The odds ratio for stem loosening was 24.86 (95% CI, 5.69-108.63) in the GB group versus the PC group.
conclusionsHip arthroplasty using cementless grit-blasted tapered-wedge titanium stems showed higher incidence of stem loosening in association with periprosthetic femur fracture than hip arthroplasty conducted using proximal porous-coated stems. A high index of suspicion of stem loosening might be necessary in periprosthetic femur fracture following hip arthroplasty using this type of stems.
