摘要
第5跖骨近端骨折是足部最常见的骨折之一,其血供特点和独有的解剖结构,使发生于骨干和干骺端交界处的骨折延迟愈合或不愈合风险较高。目前第5跖骨近端骨折的分型系统繁多复杂,尚未统一,多推荐采用Lawrence和Botte分型,该系统将第5跖骨近端骨折分为3类:结节部撕脱骨折(Zone Ⅰ)、骨干与干骺端交界处累及第4、5跖骨间关节的骨折(Zone Ⅱ)、骨干近端骨折(Zone Ⅲ)。基于该分型系统,每一类骨折都有相应的治疗方案及预后评估。第5跖骨近端骨折手术方式有多种,对于Zone Ⅱ和Zone Ⅲ骨折,经皮髓内螺钉技术是目前的首选术式。此外,临床工作者也应对该骨折的常见并发症及相关处置方法有深入的了解。
As one of the most common fractures of the foot,the blood supply characteristics and unique anatomy of proximal fifth metatarsal fracture makes a high risk of delayed union or non-union of fractures occurring at the junction of the diaphyseal-metaphyseal.At present,the classification system of proximal fifth metatarsal fracture is complicated and not yet unified,and Lawrence and Botte classification is more recommended.The system divides proximal fifth metatarsal fracture into three types:avulsion fractures of tuberosity(ZoneⅠ),fractures at the metaphysis-diaphysis junction,which extend into the fourth-fifth intermetatarsal facet(ZoneⅡ)and the proximal diaphyseal fractures(ZoneⅢ).Based on the classification system,each type of fracture has a corresponding treatment plan and prognosis.There are a variety of surgical methods for proximal fifth metatarsal fracture.For the fracture of ZoneⅡand ZoneⅢ,percutaneous intramedullary screw is the first choice.In addition,clinicians should also have a thorough understanding of common complications of fracture and associated disposal methods.
