摘　　要：背景:对稳定型舟骨骨折行内固定治疗与保守治疗相比可提高骨折愈合率、缩短骨折愈合及石膏外固定时间。目的:对使用空心螺钉和克氏针内固定治疗腕舟骨骨折方法和进展进行归纳总结,比较不同金属植入物内固定治疗腕舟骨骨折临床应用的安全性和远期疗效。方法:第一作者应用计算机检索PubMed数据及CNKI数据库,在标题和摘要中以"不同植入材料,腕舟骨骨折,内固定材料"或"Carpal bone,fracture ununited"为检索词纳入与有关生物材料与组织工程血管相关的文章;以25篇文献为主重点进行了讨论。结果与结论:采用带有血液供应的骨瓣、骨膜移植技术治疗腕舟骨陈旧性不愈合,并加用克氏针、herbert钉、空心螺钉等内固定材料,取得了较为满意的疗效。采用空心螺钉内同定治疗可减少骨折不愈合率,促进腕关节功能恢复,改善预后,并具有多轴向、多平面稳固固定的特点,与克氏针内固定等材料相比较仍具有较优良的临床应用价值。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.
