Patients with an acetabular fracture treated with acute total hip arthroplasty and additional fixation: a cohort study with functional and radiological follow-ups.

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
background and purposeElderly patients with acetabular fractures are associated with complex fracture patterns and poor bone quality. Internal fixation alone in these patients has been associated with poor outcome. Internal fixation combined with acute total hip arthroplasty (THA) has been introduced as a surgical option aimed to allow early recovery of hip function and mobility. However, functional and radiological data are still limited. The aim of our study was to elucidate radiographic and functional outcomes, and complications in elderly patients with an acetabular fracture treated with acute THA and additional fixation (reinforcement ring and/or plate fixation).
methodsPatients ≥ 60 years with an acetabular fracture treated with acute THA and additional acetabular fixation were followed up at least 1 year postoperatively. Medical records were reviewed, and functional examinations and radiographic assessments were performed.
results84 patients were identified, of whom 32 completed all follow-ups. The median (IQR, range) age was 77 (35, 60-95) years and 7 of 32 were females. Dome impaction was the main indication for THA in 30 and the median follow-up time was 3.1 years. 2 patients had a postoperative hip dislocation. 3 patients had a deep infection and 7 sustained at least 1 non-surgical complication. The median Harris Hip Score was 87 (33, 33-100) and the median EQ-5D-3L index score was 0.7 (0.5, 0.0-1.0). No radiological signs of loosening of the acetabular reinforcement ring or the cup were observed. The 1-year mortality for the whole eligible cohort was 13% (n = 9/72).
conclusionInternal fixation with acute THA in elderly acetabular-fracture patients resulted in good functional outcomes with no signs of acetabular implant loosening, but a high complication rate.
