“…Furthermore, compared to X-ray, ultrasonography allowed evaluation of real-time movement of the volar plate during active or passive movements of the PIP. More importantly, as everyone knows, ultrasound was a non-radioactive imaging method compared to X-ray [ 11 , 12 ]. Therefore, we can use ultrasound to observe the change of thickness of the injured volar plate in the following-up after treatment [ 13 ].…”

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.

“…Tendon static dimensions Accurate measurement of the Cross-Sectional Area (CSA) of tendons is a prerequisite for studying tendon plasticity under load [13][14][15] . Research indicates that tendon thickening is an adaptive response to long-term exercise and is also associated with tendinopathy [16,17] . In addition, an accurate assessment of potential tendon autograft size before ACL reconstruction is vital for achieving dimensional reproduction of the reconstructed ACL [18,19] .…”

Research on tendon biomechanics and metabolism spans several decades. However, most previous tendon experiments have used animal models in vitro cell cultures, among other methods. Factors such as anatomical and metabolic distinctions between these models and isolated cell cultures detached from the human physiological environment may lead to a biased interpretation of experimental results. Recently, advancements in human tendon detection methodology have sparked interest in studying human tendon biomechanics and metabolic cycles, consequently generating numerous related studies. This study aimed to summarize novel methods for detecting biomechanical and metabolic changes in human tendons over the past two decades. It is a valuable reference in this research field and elucidates potential future direction for human tendon detection and research endeavors.

Tendon disorders commonly cause hand and wrist disability and curtail the performance of work-related duties or routine tasks. Imaging is often needed for diagnosis, but it requires knowledge of the complex anatomic structures of the tendons of the hand and wrist as well as familiarity with related disorders. This review article aims to provide medical professionals with guidelines for the sonographic assessment of the tendons of hand and wrist and related disorders. Sonographic features of tendon disorders affecting the hand and wrist are described here, specifically: infectious tenosynovitis; tendon rupture or tearing; stenosing forms of tenosynovitis such as De Quervain disease and trigger finger; intersection syndrome; insertional tendinopathy; several forms of tendinous instability such as extensor carpi ulnaris instability, climber finger, and boxer knuckle; and tendinopathy in inflammatory rheumatic diseases. Postsurgical evaluation of the hand and wrist tendons is also discussed, including the healthy and pathologic appearances of operated tendons as well as impingement from orthopedic hardware. In conclusion, sonography is effective in assessing the tendons of the hand and wrist and related disorders and represents a valuable tool for diagnosis.

Thickness of Extensor Tendons at the Proximal Intersection

Abstract: Normal tendon thickness should be between 0.30 and 0.40 cm in women and 0.36 and 0.48 cm in men. A comparison between asymptomatic and symptomatic sides and proximal and distal measurements is recommended.
