“…Its US mean thickness was 0.41 ± 0.10 mm in the posterior region and 0.40 ± 0.10 mm in the anterior region ( Table 4 and Figure 3 ). It was thicker at Post 2 level, probably because of the proximity to the wrist, where the superficial fascia and deep fascia merge to form the extensor wrist retinacula [ 21 ]. Therefore, the differences between the arm and forearm were statistically significant ( Table 6 ) within different regions/levels.…”

The superficial fascia has received much attention in recent years due to its important role of compartmentalizing the subcutaneous tissue. Ultrasound (US) imaging, owing to its high definition, provides the possibility of better visualizing and measuring its thickness. The aim of this study was to measure and compare, with US imaging, the thickness of superficial fascia in the arm and forearm in different regions/levels. An observational study has been performed using US imaging to measure superficial fascia thickness in the anterior and posterior regions at different levels in a sample of 30 healthy volunteers. The results for superficial fascia thickness revealed statistically significant differences (p < 0.0001) in the arm between the anterior and posterior regions; in terms of forearm, some statistically significant differences were found between regions/levels. However, in the posterior region/levels of the arm, the superficial fascia was thicker (0.53 ± 0.10 mm) than in the forearm (0.41 ± 0.10 mm); regarding the anterior regions/levels, the superficial fascia of the arm (0.40 ± 0.10 mm) was not statistically different than the forearm (0.40 ± 0.12 mm). In addition, the intra-rater reliability was good (ICC2,k: 0.88). US helps to visualize and assess the superficial fascia inside the subcutaneous tissue, improving the diagnosis of fascial dysfunction, and one of the Us parameters to reliably assess is the thickness in different regions and levels.

“…In cases of ruptures, either the pulley cannot be clearly/directly visualized or the characteristic/indirect finding of flexor tendon dislocation (away from the adjacent cortex) can be observed as “bowstringing.” The patient can be asked to perform resisted flexion with his fingertip against the examiner to increase the diagnostic certainty whereby the tendons will normally remain adjacent to the underlying bony surface (Video 32, http://links.lww.com/PHM/B628). While maximal bowstringing over the proximal phalanx indicates an A2 pulley injury (Video 33, http://links.lww.com/PHM/B629), in A4 pulley injuries, the bowstringing is mostly pronounced at the middle phalanx level 43 …”

“…In the early stage, volar plate injury presents with instability of joint. If combined with collateral ligament injury, instability of joint flexion and lateral deviation will both occur, which may become an obstacle to the reduction of joint dislocation [ 1 – 3 ]. Although clinicians can make the diagnosis of acute closed volar plate injury according to the symptoms and signs, there are few objective evaluation imaging methods for the degree of acute closed volar plate injury [ 4 – 6 ].…”

Background Acute closed volar plate injury of the proximal interphalangeal joint (PIP) is a common hand injury. In the past, there were few objective evaluation imaging methods for the degree of volar plate injury. The purpose of this study was to investigate the role of high frequency ultrasonography in diagnosing volar plate injury, and to explore whether ultrasound can provide a beneficial guidance to clinical decision-making and appropriate treatment adopting through accurate US classification of volar plate injury. Methods From May 2019 to may 2022, 41 patients diagnosed with volar plate injury were included in this study. All patients underwent ultrasonography and X-ray examinations. The sonographic features were analyzed. A new kind of classification of volar plate injury based on ultrasonography findings was described. Results Either an injury of volar plate or an avulsion fracture of middle phalangeal base was identified clearly on ultrasonography, according to which volar plate injury could be divided into three types: A, B and C. Type A, avulsion fracture of the middle phalangeal base without volar plate rupture; Type B, full thickness tear of the volar plate without avulsion fracture; Type C, partial thickness tear of the volar plate. The average thickness of the three types of injured volar plate measured by ultrasound was 0.33 ± 0.05 cm, and the average thickness of the volar plate at the same site of the corresponding finger on the contralateral side was 0.22 ± 0.03 cm. There was significant difference between the two group (t = 11.823, p = 1.2476 *10^(-14)). Conclusions High frequency ultrasonography could be a reliable, accurate, convenient and non-radioactive diagnostic imaging technique in the evaluation of acute closed volar plate injury of PIP. And ultrasound could provide a beneficial guidance to clinical decision-making and appropriate treatment adopting through accurate US classification.
