Development and Clinical Application of Percutaneous Compressive Locking Intramedullary Nail for Humerus

removal and larger fixing force, and has no need for external fixation [2].Therefore, intramedullary fixation is used more and more in clinical practice [3].However, intramedullary nails currently used are complicated in structure, cumbersome to operate, and require open reduction, open nailing and second operation for removal.This brings great pain and large cost to patients.Additionally, intramedullary nails currently used lack compression at the fracture sites, likely leading to delayed healing or even no healing.In view of this, we carefully studied the anatomical characteristics of humerus, and developed the Simple Percutaneous Compressive Locking Intramedullary Nail (SPCLIN).We have done 1078 clinical trials, and got good results, which are summarized in this study.
