Risk factors of neck re-shortening after reduction and fixation in patients with valgus-impacted femoral neck fractures.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundTo analyze the risk factors of neck re-shortening after reduction and fixation in patients with valgus-impacted femoral neck fractures. MATERIAL AND
methodsAnalysis of the clinical data of 46 cases with valgus-impacted femoral neck fractures treated by one surgeon in our hospital from January 2020 and December 2023. The collected clinical data includes: patient's gender, age, body mass index (BMI) and American Society of Anesthesiologists (ASA) classification, fracture side, Cause of injury, time from injury to surgery, Pauwels angle, valgus angle, posterior tilt, Hounsfield units of femoral neck from CT scan, surgical time, internal fixation method, blood loss in operation. SPSS 26.0 software (univariate analysis and Logistic regression analysis) was used to simulate a decision analysis and find risk factors.
results17 of 46 patients who were included in the study developed neck re-shortening after surgery, with an incidence rate of 37.0%. Univariate analysis showed that there were significant differences in age(P = 0.004), valgus angle(P < 0.001), femoral neck CT HU value(P < 0.001). Logistic regression analysis showed that age > 53.5 years (OR 4.821, 95% CI: 1.248-18.624), initial valgus angle was > 17.6° (OR 2.417, 95% CI: 1.567-3.727), and femoral neck CT HU ≤ 92.5(OR 15.500, 95% CI: 4.057-59.222) were risk factors of postoperative neck re-shortening(P < 0.05).
conclusionAge, valgus angle, femoral neck CT HU value may be risk factors of neck re-shortening after surgery. For patients with high risk factors, in situ fixation may be a choice, but for young patient with good bone quantity, fixation after reduction is a better choice, which may be beneficial for reconstruction normal hip function.
