Periacetabular Osteotomy Improves Hip Microinstability Between Supine and Standing Radiographs in Symptomatic Hip Dysplasia.
Orthop J Sports Med
March 2025
Department of Mechanical & Aerospace Engineering, University of Florida, Gainesville, Florida, USA.
Background: Whether periacetabular osteotomy (PAO) improves hip microinstability in patients with symptomatic hip dysplasia remains poorly understood.
Purpose: To assess the femoral head translation with static postural change, considered a potential indicator of hip microinstability, comparing dysplastic hips before and after PAO with normal hips.
Study Design: Descriptive laboratory study.

Department of Orthopaedic Surgery, Kyoto University Hospital, Kyoto, Japan.
Background: This study aimed to measure the optimal osteotomy angle and length, as well as the available width of the osteotomy site in the posterior column for the safe performance of periacetabular osteotomy.
Methods: Fifty-six hips in 41 patients who underwent curved periacetabular osteotomy were evaluated. Computed tomography data were subjected to multiplanar reconstruction to measure parameters in two reference planes: the functional pelvic plane and the anterior pelvic plane.
Characteristic analysis and surgical exploration for acetabular roof fractures: Multicenter retrospective cohort study.

Department of Orthopaedics, Hebei Medical University Third Hospital, Shijiazhuang, China.
Background: Acetabular roof was a crucial structure for maintaining the stability of hip joint; however, its important role was not especially emphasized in the Letournel-Judet classification system. Acetabular roof was segmented into the roof column and roof wall in Three-column classification and fracture in this area alone was defined as A3 injury. The purpose of this study was to explore the characteristics and surgical strategy of A3 injury.

January 2025
Balgrist University Hospital, Orthopaedic Department, University of Zurich, Zurich, Switzerland.
Background: Identifying hip instability in symptomatic patients with borderline dysplasia of the hip (BDH) is of paramount importance, as it can influence both surgical decision-making and surgical outcomes. The femoroepiphyseal acetabular roof (FEAR) index is strongly affected by the hip adduction/abduction angle during the pelvic radiograph, which has not yet been considered in the recommended threshold values.
Purpose: To compare the corrected FEAR index in symptomatic patients with BDH treated with pelvic periacetabular osteotomy (PAO) or hip arthroscopy.
