Mallet finger is a common injury of the extensor tendon insertion causing an extension lag of the distal interphalangeal joint.
We reviewed the most current literature on the epidemiology, diagnosis, and management of mallet finger injuries focusing on the indications and outcomes of surgical intervention.
Nonoperative management has been advocated for almost all mallet finger injuries; however, complex injuries are usually treated surgically. There is still controversy regarding the absolute indications for surgical intervention.
Although surgery is generally indicated in the case of mallet fractures involving more than one-third of the articular surface as well as in all patients who develop volar subluxation of the distal phalanx, a significant advantage of surgical management even in those complicated cases has yet to be clearly proven.
锤状指是伸肌腱止点处的常见损伤，可导致远侧指间关节伸展滞后。
我们回顾了关于锤状指损伤的流行病学、诊断和治疗的最新文献，重点关注手术干预的指征和结果。
几乎所有锤状指损伤都主张非手术治疗；然而，复杂损伤通常采用手术治疗。手术干预的绝对指征仍存在争议。
虽然对于累及超过三分之一关节面的锤状骨折以及所有出现远节指骨掌侧半脱位的患者通常建议手术治疗，但即使在这些复杂病例中，手术治疗的显著优势尚未得到明确证实。
