Sumario:The purpose of this study was to compare the pre and postoperative radiographic findings and analyze the complication rate with respect to the laterality in periacetabular osteotomy in right-handed surgeons. Satisfaction rate and radiographic findings were prospectively collected between 2017 and 2019 and retrospectively reviewed. For analysis, all measurements of the CT scans were performed by a musculoskeletal fellowship-trained radiologist. Complications were classified into two categories: perioperative or postoperative. All surgeries were performed by three right-hand dominant hip surgeons. A total of 41 dysplastic hips (25 right and 16 left hips) in 33 patients were included. Postoperatively, a significantly lower acetabular index angle on the left side was observed at −2.6 ± 4.3 as compared to the right side at 1.6 ± 6.5 (p < 0.05). The change in Center edge (CE) angle was significantly lower for the left side 13.7 ± 5.5° than on the right side, measured at 18.4 ± 7.3 (p < 0.001); however, the overall CE angle was comparable at 38.5 ± 8.9° without any significant difference between the operated hips (left side at 37.8 ± 6.1° versus right side at 39.0 ± 10.3; p = 0.340). No significant differences in other radiographic measurements or surgical time were observed. For complications, the right side was more commonly affected, which may also explain a higher satisfaction rate in patients who were operated on the left hip with 92.3%. The change in lateral CE angle was significantly lower for the left side and the right hip seems to be predisposed to complications, which correlate with a lower satisfaction rate in right-handed surgeons.
