Reconstruction of the acetabular roof in patients with hip dysplasia shows disappointing mid-term results due to insufficient incorporation and collapse of the bone graft. We have developed a new reconstructive method using a pedicled iliac graft. We simulated surgical reconstruction of the acetabular roof in ten cadaver specimens. The purpose was to evaluate whether the deep circumflex artery was long enough to allow transfer of the graft without requiring micro-vascular anastomosis. In all cadavers, the length of the pedicle was sufficient to reach any desired position of the acetabular roof. The use of such a pedicled structural graft may provide good primary stability and allow local bony remodelling and incorporation under load.

Association between acetabular coverage over femoral head and rate of joint space narrowing in non-arthritic hips.

Aims: This study was performed to investigate the association between the acetabular morphology and the joint space narrowing rate (JSNR) in the non-arthritic hip.
Methods: We retrospectively reviewed standing whole-leg radiographs of patients who underwent knee arthroplasty from February 2012 to March 2020 at our institute. Patients with a history of hip surgery, Kellgren-Lawrence grade ≥ II hip osteoarthritis, or rheumatoid arthritis were excluded.

Rationale And Objectives: Accurate assessment of hip morphology is crucial for the diagnosis and management of hip pathologies. Traditional manual measurements are prone to mistakes and inter- and intra-reader variability. Artificial intelligence (AI) could mitigate such issues by providing accurate and reproducible measurements.

Matta's Roof Arc Angle (RAA) is utilised to evaluate the load-bearing dome in cases of acetabular fractures, assisting clinicians in making informed decisions regarding treatment options through the measurement of angular displacement. This assessment is crucial for the assessment of acetabular coverage and the stability of the femoral head, helping to determine whether surgical intervention or non-operative approaches are more suitable. Nevertheless, the variability of this method underscores the importance of incorporating additional criteria to ensure the best possible clinical outcomes for patients.

Purpose: The aim was to find bony landmarks of the pelvis for the origins and routes of uterine arteries, hoping to improve speed and safety of embolization procedures (leiomyoma, post-partum bleedings…).
Methods: We carried out a study based on the analysis of CT-angiographies in arterial phases of whole-body scans. Two measurements were done per artery, one from the origin of uterine arteries to a first perpendicular line passing through the lowest part of the sacroiliac joint, another one from the beginning of the parametrial segment from a second parallel line passing by the acetabular roof.
