Orthopedic Surgeons' Accuracy When Orienting an Acetabular Cup. A Comparison with Untrained Individuals.

Previous studies demonstrated a huge variability among surgeons when it comes to reproducing the position of an acetabular cup in total hip arthroplasty. Our main objective is to determine if orthopedic surgeons can replicate a given orientation on a pelvic model better than untrained individuals. Our secondary objective is to determine if experience has any influence on their ability for this task.

Labral reconstruction with tendon allograft: histological findings show revascularization at 8 weeks from implantation.

This description shows the histological findings of a peroneus brevis tendon allograft used for labral reconstruction, implanted 8 weeks before being retrieved due to a postoperative complication unrelated to the graft. As far as we have knowledge this is the first description about revascularization of an allograft used for hip labral reconstruction. The histological report of the removed peroneus brevis tendon allograft shows evidence of vascular ingrowth represented by small vessels with a thin muscular wall in all layers of the graft and cellular migration mainly represented by mature fibroblasts.

Survival of hydroxyapatite-coated cups: acetabular screws involve a lower rate of revision surgery due to aseptic loosening.

Background: It is believed that the path of acetabular screws may represent a shuttle between hydroxyapatite (HA) particles and the liner. The aim was to assess the relationship between acetabular screws and revision surgery for aseptic loosening in total hip arthroplasties (THAs).

Material And Methods: A retrospective multicentric study was performed.

Innovative approach in total hip arthroplasty: supercapsular percutaneously-assisted.

Introduction: There is widespread trend in total hip replacement to limit soft tissue damage. New approaches that respect the capsule and ligaments has been recently reported. The potential advantages of this approach is to improve short-term results in terms of stability, pain, length of stay, transfusions and complications.
