Advances in Diagnostic Parameters and Surgical Techniques for Patellofemoral Instability and Extensor Mechanism Disorders: A Comprehensive Review.

Extensor mechanism misalignment in the knee, particularly patellofemoral instability (PFI), requires detailed diagnostic and therapeutic approaches. This comprehensive review intends to present recent advancements in diagnostic imaging technologies as well as surgical approaches that have significantly advanced the management of this condition. An extensive literature review covered recent studies and clinical practices related to diagnosing and treating knee extensor mechanism misalignment, such as three-dimensional imaging technologies, arthroscopic surgical techniques, postoperative rehabilitation protocols, and others.

How Is Bone Regeneration Influenced by Polymer Membranes? Insight into the Histological and Radiological Point of View in the Literature.

The aim of this study was to analyze published works that investigate the in vivo bone regeneration capacity of polymeric membranes loaded with active substances and growth factors. This scoping review's purpose was to highlight the histological and radiological interpretation of the locally produced effects of the polymer membranes studied so far. For the selection of the articles, a search was made in the PubMed and ScienceDirect databases, according to the PRISMA algorithm, for research/clinical trial type studies.

Anterior dislocation of the hip associated with intertrochanteric fracture of the femur - Case presentation.

Dislocations of the hip usually occur following high energy trauma, the coxo-femoral joint being inherently stable, and can be associated with acetabular fractures or fractures of the head, neck or shaft of femur. However, the combination between the anterior hip dislocation and the ipsilateral intertrochanteric fracture is extremely rare, the literature offering only scarce information. We present the case of a patient, aged 44, victim of a trauma by precipitation from height (12m), diagnosed with left hip anterior dislocation and intertrochanteric fracture of the ipsilateral femur.
