Humerus intramedullary nail

Unlike traditional plates placed externally on bones, intramedullary nails serve as an “internal support” positioned along the bone's mechanical axis. This centralized fixation method minimizes the lever arm, providing exceptional resistance to bending and rotation. It allows patients to initiate functional exercises and partial weight-bearing early on, significantly accelerating recovery. Additionally, the procedure typically employs minimally invasive techniques, with insertion through small incisions distant from the fracture site. This approach maximally preserves blood supply and soft tissue integrity around the fracture, creating an optimal biological environment for bone healing. Consequently, the risk of infection and nonunion is significantly reduced.

Conclusion

Clinical studies demonstrate that compared to locking plates, intramedullary nail systems significantly reduce intraoperative blood loss, shorten surgical and fracture healing times, and better preserve the humeral neck-shaft angle when treating proximal humeral fractures in adults, thereby facilitating shoulder joint function recovery. The humeral intramedullary nail (particularly multidimensional locking systems) achieves mechanical stability through its design principles of “intramedullary fixation, minimally invasive implantation, and anatomical optimization.” This approach maximizes biological preservation and facilitates early functional recovery, making it an optimal choice for treating complex proximal humeral fractures and elderly patients with osteoporosis.
