Calcitonin gene-related peptide (CGRP) has 37 amino acids. Initially, CGRP had vasodilatory and nociceptive effects. As research progressed, evidence revealed that the peripheral nervous system is closely associated with bone metabolism, osteogenesis, and bone remodeling. Thus, CGRP is the bridge between the nervous system and the skeletal muscle system. CGRP can promote osteogenesis, inhibit bone resorption, promote vascular growth, and regulate the immune microenvironment. The G protein-coupled pathway is vital for its effects, while MAPK, Hippo, NF-κB, and other pathways have signal crosstalk, affecting cell proliferation and differentiation. The current review provides a detailed description of the bone repair effects of CGRP, subjected to several therapeutic studies, such as drug injection, gene editing, and novel bone repair materials.

Background: The efficacy of bone marrow aspirate concentrate (BMAC) in promoting bone-tendon interface (BTI) healing without any carriers remains a subject of debate.

Purpose: To evaluate BMAC effects with different carriers on tendon regeneration in a rabbit model of chronic rotator cuff tear.

Study Design: Controlled laboratory study.

The understanding of neuroimmune function has evolved from concepts of immune privilege and protection to a new stage of immune interaction. The discovery of skull meninges channels (SMCs) has opened new avenues for understanding central nervous system (CNS) immunity. Here, we characterize skull bone marrow and SMCs by detailing the anatomical structures adjacent to the skull, the differences between skull and peripheral bone marrow, mainstream animal processing methods, and the role of skull bone marrow in monitoring various CNS diseases.

A patient in his early adolescence, who was treated for T5-T6 tubercular spondylodiscitis with an un-instrumented decompression, presented at 36 months post-index surgery, for post-laminectomy instability and kyphosis, after completing his requisite antitubercular treatment. He underwent thoracic posterior instrumented kyphosis correction and anterior reconstruction, with a T5-T6 partial corpectomy and corpectomy spacer placement, through a posterior midline incision. On the second postoperative day, he started complaining of pain on the left side of his chest, abdomen and left shoulder.

Objectives: Long bone fractures with concomitant vascular injury have the potential to be life and limb threatening injuries, with increased risk for limb loss. There is currently no established surgical order of operations for orthopaedic and vascular intervention. This study compares injury classification, warm ischemia time and patient outcomes in patients with long bone fractures and associated vascular injury after orthopaedic versus vascular primary intervention.

Osteomyelitis, a severe bone infection, is an extremely challenging complication in the repair of traumatic bone defects. Furthermore, the use of long-term high-dose antibiotics in standard treatment increases the risks of antibiotic resistance. Herein, an antibiotic-free, collagen silver-doped hydroxyapatite (coll-AgHA) scaffold reinforced with a 3D printed polycaprolactone (PCL) framework was developed with enhanced mechanical properties to be used in the repair of load-bearing defects with antimicrobial properties as a preventative measure against osteomyelitis.
