Metastasis stands as one of the most prominent prognostic factors in osteosarcoma. Over 70% of metastatic osteosarcoma occurrences affect the lung. Nonetheless, to date, there has been a scarcity of research addressing predictive factors for lung metastasis risk in osteosarcoma.

The aim of this study was to evaluate the role of CFR-PEEK nails in patients with metastatic bone disease (MBD). We performed a retrospective cohort study evaluating patients with MBD undergoing intramedullary (IM) nailing for prophylaxis or fixation of pathological fractures using CFR- PEEK or titanium implants.

Background: Gravid females with pelvic fractures are rarely encountered by the orthopaedic trauma surgeon. The initial injury can be detrimental to the pregnant patient, but an unnecessary "second hit" from surgery could also contribute to the outcome of the fetus. Understanding the surgical risks for this unique patient population requires knowledge about the negative effects of anesthesia, surgical exposures, and radiation.

Background: Complicated crown-root fracture (CRF) involves severe injury to the crown, root, and pulp, and may be accompanied by multiple root fractures. The loss of a tooth has lifelong consequences for children and teenagers, but the maintenance of pulp health and the calcific healing of multiple root fractures are rarely reported in the literature.
Case Summary: This case reports healing of a permanent tooth with complicated crown-root and additional root fractures, in which pulp health was maintained.

A potential two-way passage of cells and substances between the brain and skull bone marrow may open for new insights into neurological disease. The arachnoid membrane was traditionally considered to restrict cells and larger molecules in CSF from entering the dura and bone marrow directly. However, new data on exchange between brain and skull bone marrow have recently emerged.
