To compare perioperative blood loss patterns between patients undergoing varus derotation osteotomy (VDRO) alone and those undergoing VDRO combined with Dega osteotomy. This retrospective case-control study was conducted on patients who underwent VDRO or VDRO with Dega osteotomy for developmental hip dysplasia between 2018 and 2025. Patients were categorized (a) VDRO with Dega osteotomy and (b) VDRO. Demographic characteristics, pre- and postoperative complete blood count, blood loss, surgical duration, and transfusion requirements were recorded. Visible blood loss, hidden blood loss (HBL), and total blood loss (TBL) were calculated. Factors associated with HBL were identified through regression analysis. A total of 90 patients met the inclusion criteria, 31 in the VDRO group (mean age: 47.1 ± 30.1 months) and 59 in the VDRO + Dega osteotomy group (51.3 ± 36.3 months). The surgical duration (122.3 ± 17.1 vs. 76.3 ± 13.3 min; P < 0.001), the need for blood transfusion (30.5 vs. 9.7%; P = 0.035), and the percentage of HBL in TBL (56.7 ± 20.8 vs. 46.9 ± 11.6; P = 0.008) were significantly higher in the VDRO + Dega osteotomy group. Regression analysis revealed weight (β: 0.329, P = 0.001) and surgical duration (β: 0.273, P = 0.016) as independent predictors of the percentage of HBL in TBL. Patients who underwent Dega osteotomy with VDRO had higher HBL levels, both in absolute volume and as a proportion in TBL, compared to those who underwent VDRO alone. Therefore, HBL should be carefully evaluated in the perioperative blood loss management of patients undergoing periacetabular and femoral osteotomies.
