Thumb extensor injuries and bony avulsion in the distal phalanx of the thumb are rare compared with other fingers. The most reported complications are infection, nail deformity, joint incongruity, implant failure, recurrent flexion deformity, and residual pain. This report presents a case of 30-year-old man suffering from an injury in the left thumb distal phalanx with a displaced comminuted intra-articular fracture of the distal phalanx of the left thumb. The nail plate was interposed between the dorsal and palmar fragments. The interposition of the nail plate in the bony mallet thumb has not been described before. Surgical treatment and fixation with a 2-mm miniscrew resulted in successful treatment. Clinical suspicion of this complication is of great importance and can affect treatment outcomes.
与其他手指相比，拇指伸肌损伤和拇指远节指骨的骨质撕脱较为罕见。报道最多的并发症是感染、指甲畸形、关节不平整、植入物失败、复发性屈曲畸形和残留疼痛。本报告介绍了一名30岁男性，其左拇指远节指骨受伤，伴有左拇指远节指骨移位粉碎性关节内骨折。甲板夹在了背侧和掌侧骨折块之间。甲板夹在槌状拇指骨折中的情况此前未见报道。采用2毫米微型螺钉进行手术治疗和固定取得了成功。对这种并发症的临床怀疑非常重要，可能会影响治疗结果。
