摘　　要：锤状指损伤是指由于终末伸肌装置连续性中断而形成以远指间关节(DIP)屈曲为特征的畸形,关节丧失主动背伸功能。一般是由创伤造成的手指伸肌腱I区断裂或远节指骨基底部背侧撕脱骨折所致。目前锤状指的治疗选择存在争议,治疗方式选择不当不仅不能纠正指体的畸形,改善患指功能,甚至会引起一些难以弥补的并发症。本文结合国内外的文献讨论锤状指的非手术治疗及手术治疗的指征、固定方式等诊疗要点,以期提高及改善患者的预后。Mallet finger is a common injury,which refers to the deformity characterized by the flexion of distal interphalangeal joint(DIP)due to the interruption of the continuity of terminal extensor device,and the joint loses active extension function.Generally,it is the rupture of extensor tendon area I of finger or the dorsal avulsion fracture of distal phalanx base caused by trauma.At present,the choice of conservative and surgical treatment of mallet finger is still controversial in China.The improper choice of treatment can not correct the deformity of finger body and improve the function of the affected finger,and cause some irreparable complications.Combined with Chinese and foreign literatures,this paper reviews and analyzes the classification of mallet finger,indications of conservative treatment and surgical treatment,fixation methods and other key points of diagnosis and treatment,in order to improve the outcome of patients.
