Intraoperative periprosthetic femoral fracture in cementless hip hemiarthroplasty for femoral neck fracture does not change long-term outcomes.

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
purposeIntraoperative periprosthetic femoral fracture (IPFF) is a known complication during hemiarthroplasty (HA), which may lead to inferior outcomes. Few studies have assessed the outcomes of IPFF in HA for displaced femoral neck fractures (FNF). This study aims to evaluate the incidence of IPFF in cementless HA for displaced FNF and compare long-term outcomes between patients with and without IPFF.
methodsWe retrospectively reviewed institutional surgical data of patients who underwent cementless HA for displaced FNF from January 2010 to January 2022. The presence, location, and treatment of IPFF, as well as the effect of IPFF on postoperative weight-bearing, status were assessed. Mortality, readmission, and revision rates were compared between the IPFF and non-IPFF group.
resultsA total of 1,586 patients were included in the study. 104 patients (6.6%) in the IPFF group vs. 1,482 patients (93.4%) in the non-IPFF group. The IPFF location was mostly the calcar (59.6%), followed by the greater trochanter (35.5%) and the femoral shaft (8.6%). Most fractures were treated with fixation (92.3%) and full weight-bearing postoperatively (95.1%). Surgery duration was longer in the IPFF group (p < 0.001). However, there were no significant differences between groups regarding 30-day, 90-day, and 1-year mortality rates, 90-day readmission rates, or revision rates at the latest follow-up. A multivariate binary logistic regression found similar long-term results.
conclusionsWhile IPFF remains a recognized complication of cementless HA for displaced FNF, its occurrence does not adversely affect long-term outcomes when appropriately managed.
