ABSTRACT
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.
