Immune-mediated bone regeneration driven by bone biomaterials offers a therapeutic strategy for repairing bone defects. Among 2D nanomaterials, TiCT MXenes have garnered substantial attention for their potential in tissue regeneration. This investigation concentrates on the role of MXene nanocomposites in modulating the immune microenvironment within bone defects to facilitate bone tissue restoration.

Purpose: Congenital pseudarthrosis of the tibia (CPT) is a rare condition typically manifesting within the first decade of life. The primary objectives of surgical intervention for CPT include achieving long-term bony union of the tibia, preventing or minimizing limb length discrepancies (LLD), avoiding mechanical axis deviations of the tibia and adjacent joints, and preventing refracture. This study aims to conduct a systematic review of current treatment methods for CPT to determine the most effective non-surgical and surgical management strategies for pediatric patients with this condition.

Ductal carcinoma (DCIS), a noninvasive breast cancer, rarely metastasises to distant locations. When the initial lesion is stable, bone marrow metastasis (BMM) and bone marrow necrosis (BMN) are even less common. Here, we report the case of a 47-year-old female patient who underwent localized surgery and radiotherapy for right-sided DCIS.

The diagnosis of primary leiomyosarcoma (LMS) of bone is generally established based on integrative findings of morphologic features, immunohistochemical staining, and clinical and radiological findings. There are no specific genetic alterations that can be used to confirm the diagnosis of LMS in challenging diagnoses of bone sarcomas with myogenic differentiation. In this study, we assessed the utility of a DNA methylation-based classifier as an ancillary diagnostic tool for subclassifying bone sarcomas with myogenic differentiation.

Background: The use of quadriceps tendon (QT) autograft for anterior cruciate ligament (ACL) reconstruction has been increasing since 2014. Studies have shown that QT is comparable to hamstring tendon (HT) and bone-patellar tendon-bone (BTB) autografts in terms of outcomes, although QT autograft has lower rates of donor site morbidity. Systematic reviews and meta-analyses have been previously conducted on this topic, although none have focused solely on data of patients at least 5 years out from surgery.
