BACKGROUND:As compared with conservation therapy,stable internal fixation of scaphoid fracture can improve the healing rate,shorten the healing time and plaster fixed time.OBJECTIVE:To summarize the methods and progress of hollow screw and Kirschner wire in treating scaphoid fractures,and to compare the safety and long-term effect of different metal implants on scaphoid fractures.METHODS:The PubMed database and CNKI database were searched by the first author using keyword of "different implant materials,scaphoid fractures,internal fixation materials" in Chinese and "carpal bone,fracture ununited" in English.Papers related to biomaterials and tissue engineered vessels were selected.A total of 25 papers were included.RESULTS AND CONCLUSION:Bone flap with blood supply and periosteal transplantation are used in treatment of old scaphoid factures,and Kirschner screw,herbert screw,and hollow screw are applied as internal fixation materials,which have achieved a more satisfactory results.The hollow screw can reduce the nonunion rate,promote functional recovery of the wrist joint,and improve prognosis,and it can play a role of multi-axial,multi-plane stable fixation,which is a better material in clinical application.
