Vascularization and bone repair are accelerated by a series of gene-activated scaffolds delivering both an angiogenic and an osteogenic gene. Stem cell-mediated osteogenesis in vitro, in addition to increased vascularization and bone repair by host cells in vivo, is enhanced using all systems while the use of the nanohydroxyapatite vector to deliver both genes markedly enhances bone healing.

Background And Purpose:  Vascularized fibular grafting following tumor resection is an essential treatment option in limb salvage surgery. We aimed to evaluate: (I) bone healing, (II) complications and reoperations, (III) limb salvage, and (IV) survival.

Methods:  We present a retrospective evaluation of a national cohort comprising 27 patients.

Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal Gammopathy, and Skin Changes (POEMS) syndrome is a rare paraneoplastic disorder caused by plasma cell proliferation and overproduction of cytokines, particularly vascular endothelial growth factor (VEGF). This complex syndrome affects multiple organ systems and presents with a broad range of clinical and laboratory manifestations, which can complicate both diagnosis and management. Not all components of the acronym are observed in every patient, highlighting the clinical heterogeneity of the condition.

Transient osteoporosis of the hip (TOH), also known as bone marrow edema (BME), is an uncommon condition of unknown etiology. While transient osteoporosis usually affects the hip, it could affect other joints as well. The most common presentation is pain and it has been linked to reduced bone mineral density.

Distal radius fracture nonunion can result in significant deformity, loss of function, and chronic pain. Presented here is a case of distal radius nonunion that was surgically reconstructed with a pedicled distal ulna bone graft based on the periosteal branches of the posterior interosseus artery (PIA). This technique has limited prior utilization for adult distal radius nonunion treatment but offers an effective option for surgical reconstruction of distal radius nonunion with preservation of the radiocarpal joint, utilizing a less invasive surgery that also reduces hospitalization stay.

Background: Vascularized bone grafts (VBGs) are currently the main surgical option for the restoration of humeral bone defects particularly when defects are larger than 6 cm. Because it offers a strong, rapid blood supply, VBGs easily integrate into the recipient sites and undergo active resorption and remodeling into healthy bone through primary bone healing. Additionally, they support the recipient site's immune system in preventing and reducing infection.
