Article Abstract
Introduction: Surgeons performing periacetabular osteotomy (PAO) should account for proximal femoral morphology to prevent secondary femoroacetabular impingement. Herein, we aimed to clarify proximal femoral morphology in patients with developmental dysplasia of the hip (DDH).
Materials And Methods: This retrospective study included 57 patients with DDH (77 hips) who underwent PAO (DDH group). The control group comprised 30 patients (30 hips) with unilateral femoral head necrosis and contralateral unaffected hips (healthy hips). Coronal planes were created parallel to the femoral neck axis based on three-dimensional image analysis of hip computed tomography images. Coronal slices were obtained using clockwise rotation around the femoral neck axis in 15° increments, creating seven positions for measuring alpha (α)-angles. The superior and anterior directions were defined as 12 o'clock and 3 o'clock, respectively. Cam deformity was defined as an α-angle ≥60°. Outcome measurements were the α-angles of seven slices, cam deformity, and correlations between the maximum value of the α-angles and related factors.
Results: α-Angles were greater in the superior direction in the control than in the DDH group; conversely, they were greater in the anterior direction in the DDH than in the control group. The DDH group had more cam deformities than the control group. Cam deformities were more superior (12:30 to 1:00) in the control group, and more anterior (2:00 to 3:00) in the DDH group. Maximum α-angles in the DDH group correlated with superior acetabular coverage.
Conclusion: Surgeons should carefully consider acetabular version during PAO and avoid acetabular retroversion in cases with cam deformities.

Introduction: Developmental dysplasia of the hip (DDH) poses challenges for component positioning during total hip arthroplasty (THA) secondary to abnormal bone morphology, soft-tissue contractures, and hip center migration. The objective of this study was to evaluate the radiographic and clinical outcomes of THA for DDH performed with robotic assistance versus manual (M) technique.
Methods: A retrospective review identified 115 patients with Crowe II to IV dysplasia undergoing primary THA at a single institution from 2016 to 2022.

Purpose: The factors influencing patient-reported outcome measures (PROMs) in individuals with developmental dysplasia of the hip (DDH) remain poorly understood. The aim of this study was to determine the differences in hip-related PROMs in both borderline and true hip dysplasia.
Methods: A total of 245 patients with symptomatic DDH were enrolled.

Background: Patients with secondary hip osteoarthritis due to developmental dysplasia of the hip (DDH) often have abnormal femoral morphology, making stem design critical for long-term outcomes. The FMS-anatomic stem previously demonstrated favourable mid-term results. Its successor, the Anatomic Fit stem, was developed with a reduced hydroxyapatite-coated area to enhance proximal load transfer and a narrower lateral flare to facilitate insertion.

Background: Crowe type IV developmental dysplasia of the hip (DDH) presents unique challenges in total hip arthroplasty (THA). This study compares the clinical outcomes and efficiency of the direct anterior approach (DAA) in the lateral decubitus position combined with proximal femoral osteotomy (PFO) versus the postero-lateral approach (PLA).
Methods: A retrospective analysis of 73 hips from 64 patients who had Crowe type IV DDH was conducted.

Aims: The aim of this study was to identify a minimum set of family-centred outcomes that should be collected in research involving infants with developmental dysplasia of the hip (DDH) undergoing brace treatment.
Methods: A comprehensive list of potential outcomes was developed through a literature review and survey of key stakeholders including caregivers, clinicians, and researchers. Potential outcomes were evaluated in a two-round Delphi consensus process, which included a UK-led group with international involvement comprising orthopaedic surgeons, physiotherapists, nurse practitioners, researchers, parents, and charity representatives.
