目的探讨高频超声在急性闭合性锤状指中的应用价值.方法对36例经临床证实的急性闭合性锤状指患者进行高频超声检查,分析其声像图特征.结果高频超声均可清晰显示手指背侧伸肌腱,明确伸肌腱损伤部位及程度.36例急性闭合性锤状指患者中6例为伸肌腱完全断裂合并撕脱骨折,声像图表现为伸肌腱止点处连续性中断,伸肌腱挛缩增粗,伸肌腱远心端可见强回声撕脱骨片;22例为伸肌腱于止点处完全断裂,无撕脱骨折,声像图表现为伸肌腱于止点处连续性中断,断端挛缩增粗;8例为伸肌腱部分撕裂,声像图表现为伸肌腱止点处增粗,回声减低,部分纤维束尚连续.结论高频超声是诊断急性闭合性锤状指首选的影像学检查方法,对于临床治疗方法具有重要的指导意义.

Objective To study the clinical value of high frequency ultrasonography in acute closed mallet finger.Methods The high frequency ultrasonographic images of thirty-six patients with diagnosed acute closed mallet finger were retrospective analyzed.The ultrasonographic features were analyzed.Results The position and internal structure of extensor tendon could be showed by high frequency ultrasound,the position and injury level of acute closed mallet finger were identified.In 36 patients of acute closed mallet finger,6 cases were complete tear combined avulsion fracture,the ultrasonography showed the disruption in the extensor tendon at the level of the distal interphalangeal joint,the hyperechoic fracture fragment were found in the distal end of extensor tendon.22 cases were complete tear and no avulsion fracture,the longitudinal imaging showed the disruption in the extensor tendon at the level of the distal interphalangeal joint and the retraction of the tendon end.8 cases were partial tear,the ultrasonography showed that extensor tendons were thickened and hypoechoic,the section of extensor tendons were still continuous.Conclusions High frequency ultrasonography is the preferred imaging method for diagnosis of acute closed mallet finger,it will be important value for clinical treatment method.
