Outcomes of cannulated screw fixation for nondisplaced femoral neck fractures in patients older than 80 years: 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
backgroundThe optimal management of nondisplaced femoral neck fractures in very elderly patients remains controversial. Although hip arthroplasty is frequently advocated, internal fixation with cannulated screws may represent a less invasive alternative in carefully selected patients.
methodsA retrospective single-centre cohort study was conducted including patients aged 80 years or older with nondisplaced femoral neck fractures treated with cannulated screw fixation between 2010 and 2019. Primary outcomes were fixation failure and conversion to hip arthroplasty. Secondary outcomes included reoperation rate, radiographic fracture collapse, ambulatory status, weight-bearing protocol, and radiographic measurements related to screw positioning.
resultsA total of 170 patients were included, with a mean age of 86.9 years. Fixation failure occurred in 17 patients (10%). Reoperation for any cause was required in 15 patients (8.8%), and conversion to hip hemiarthroplasty was performed in 6 patients (3.5%). Radiographic fracture collapse was observed in 46 patients (30%), although only 7 patients (15.2%) required reoperation. Immediate full weight-bearing was not associated with increased fixation failure or fracture collapse and was associated with improved ambulatory status at 6 months. Greater femoral head occupancy on lateral radiographs was associated with fracture collapse, whereas tip-apex distance was not.
conclusionsIn carefully selected patients older than 80 years with nondisplaced femoral neck fractures, cannulated screw fixation was associated with low rates of fixation failure and conversion to hip arthroplasty. Immediate full weight-bearing did not increase complication rates and was associated with improved early mobility, supporting a less invasive treatment strategy in this super-aged population.
