Abstract:
Objective:To evaluate the role of high frequency ultrasonography in diagnosis of closed volar plate injury of proximal interphalangeal joint.Methods:From May 2015 to may 2021, 41 patients with acute closed volar plate injury confirmed by Department of Hand and Foot Surgery of the Provincial Hospital Affiliated to Shandong First Medical University were examined by high frequency ultrasonography. The sonographic features were analyzed and classified.Results:High frequency ultrasonography could not only clearly show the thickness, shape and echo of volar plate, but also the degree of injury and avulsion fracture of volar plate, according to which the closed volar plate injury could be divided into three types: A, B and C. Type A(13 cases): Avulsion fracture of the middle phalangeal base was found with volar plate rupture, the sonogram showed that the continuity of the volar plate attachment of the middle phalangeal base was interrupted, and avulsion fracture was found at the distal end of the volar plate. Type B(11 cases): Complete rupture of the volar plate attachment of the middle phalangeal base was found without avulsion fracture, the sonogram showed that the continuity of the volar plate attachment of the middle phalangeal base was interrupted, and the end of the volar plate contracted and thickened. Type C(17 cases): Tear of the volar plate was found, the sonogram showed enlarging volar plates, heterogeneous internal echo, and liquid dark area was visible in some cases. The average thickness of the three types of closed volar plate injury of the proximal interphalangeal joint measured by ultrasound was (0.33±0.05)cm, and the average thickness of the volar plate at the same position of the corresponding finger on the opposite side was (0.22±0.03)cm. There was significant difference between the two groups ( t=7.864, P=0.006). Conclusions:High frequency ultrasonography is the preferred imaging examination method for the diagnosis of closed volar plate injury in proximal interphalangeal joint, which has an important guiding significance for the selection of clinical treatment.
