The device may also house biologic agents and accommodate an autologous product. In some embodiments, the medical device is a bone screw or a pedicle screw, designed to reduce common issues such as screw loosening, screw backout, and rod breakage. The method of treatment involves implanting the medical device into a patient's bone to aid fracture healing.

This invention provides a pharmaceutical composition for promoting fracture healing, its preparation method, and its application. The composition, by weight, comprises 25-50 parts of an active core component, 8-25 parts of an osteogenic synergistic bioactive component, 3-15 parts of a bone-targeting transdermal penetration enhancer, and 5-15 parts of a moisturizing dispersant. The active core component is based on bone-healing traditional Chinese medicines such as calcined natural copper nanoparticles and Eupolyphaga sinensis polypeptides. The osteogenic synergistic component is based on collagen peptides of specific molecular weights and graded sodium hyaluronate. The bone-targeting transdermal penetration enhancer is a compound of eugenol and limonene. This invention utilizes a three-dimensional synergistic formulation structure and a phase-separated low-temperature preparation process, overcoming the shortcomings of traditional topical medications, such as poor transdermal targeting, weak efficacy, easy inactivation, and low safety. It can achieve targeted enrichment at fracture ends, synergistically promoting fracture healing throughout its entire life cycle, and simultaneously repairing bone and soft tissue. It is suitable for promoting the repair of various fractures and possesses extremely high clinical value and promising prospects for widespread application.
