Increased stability of short femoral stem through customized distribution of coefficient of friction in porous coating.

Stress shielding and aseptic loosening are complications of short stem total hip arthroplasty, which may lead to hardware failure. Stems with increased porosity toward the distal end were discovered to be effective in reducing stress shielding, however, there is a lack of research on optimized porous distribution in stem's coating. This study aimed to optimize the distribution of the coefficient of friction of a metaphyseal femoral stem, aiming for reducing stress shielding in the proximal area.

Intrapelvic Cup Migration Following Revision Total Hip Arthroplasty: A Case Report and Review of the Literature.

Intrapelvic acetabular cup migration is a rare but serious complication that can occur following either primary or revision total hip arthroplasty. Medial acetabular wall weakening is considered the main predisposing factor for acetabular protrusion. A thorough preoperative plan is essential to advocate proper pelvic anatomy reconstruction, including osteosynthesis of the pelvis, if necessary, preservation of muscle and bone stock, and selection of the right prosthetic components without damaging adjacent anatomical structures.

Fracture of femoral neck in modular total hip arthroplasty: a systematic review of the literature.

Background: Modular femoral stems have the advantage of anatomic hip reconstruction by restoring the femoral offset thus minimising the bearing surface wear, implant loosening and dislocation.

Aim: This study aims to investigate the existing literature on modular neck fractures, to identify predisposing factors and guide the decision-making process in the management of these difficult cases.

Methods: A systematic literature review was conducted until July 2022.

Prevalence, Risk Factors, and Economical Cost of Work-Related Injuries Among Olive Workers in the Achaia Region, Greece.

Background Olive gathering involves tree climbing, carrying heavy loads, navigating rough terrain, and using sharp tools. However, little is known about occupational injuries among olive workers. The aim of this study is to evaluate the prevalence and risk factors of occupational injuries among olive workers in a rural Greek area and to assess the financial burden on the health system and insurance funds.
