Conventional versus computer-tomography based navigation assisted eccentric rotational acetabular osteotomy in less experienced surgeons.

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
introductionThe use of navigation systems may improve the preoperative planning and outcomes of less-experienced surgeons for periacetabular osteotomies. This study aimed to evaluate the clinical outcomes of conventional and navigation-guided eccentric rotational acetabular osteotomy (ERAO).
methodsThe inclusion criteria were patients that underwent ERAO performed by less experienced surgeons (performing ERAO less than 25 cases) for hip dysplasia between January 2016 and December 2022. The study group was divided into the conventional (38 patients, 42 hips) and navigation groups (32 patients, 34 hips). Assessment tools included the operative time, blood loss, preoperative and final follow-up Harris Hip Scores (HHS), complications, and acetabular imaging parameters.
resultsThe study included a total of 70 patients (6 men and 64 women, average age of 35.1 years, 76 hip joints). There were no significant differences in the operative time, intraoperative blood loss, and preoperative and final HHS scores between the two groups. Complications were observed in 10 (24%) and 3 (9%) hip joints in the conventional and navigation groups, respectively. Conversion to total hip arthroplasty was performed in two hip joints (5.4%) in the conventional group and none in the navigation group. The postoperative lateral center edge angle and acetabular head index were significantly greater in the navigation group than in the conventional group. DISCUSSION: This study demonstrated that even less experienced surgeons can reduce complications and achieve favorable acetabular coverage with ERAO using navigation systems.
