“…However, only a few studies (Boutry et al 2005; Guerini et al 2008; Khoury et al 2007;Kim and Lee 2010;Klauser et al 2004;Lee et al 2000;Serafini et al 1996;Tagliafico et al 2009) have used this method to evaluate flexor digit tendons for trigger digit. Some of these studies (Boutry et al 2005;Guerini et al 2008;Kim and Lee 2010;Serafini et al 1996) have reported specific ultrasonographic findings with respect to trigger digit.…”

“…In the longitudinal plane, we measured the thicknesses of the flexor digit tendons at three points: the A1 pulley tunnel inlet (Inlet, at the point of the metacarpal head-neck junction); the A1 pulley tunnel outlet (Outlet, at the point of the proximal phalangeal base-shaft junction); and the A1 pulley tunnel (Interpulley, middle of Inlet and Outlet) (Chern et al 2005;Klauser et al 2004) (Fig. 1).…”

“…It has been an ideal imaging tool in the initial investigation of flexor digit tendons (Chern et al 2005;Khoury et al 2007;Klauser et al 2004;Lee et al 2000;Serafini et al 1996) and can be helpful in the evaluation of trigger digits. In trigger digit, ultrasonography can reveal effusion or abnormality of the flexor digit tendons and surrounding structures and impairment of tendon gliding.…”

“…Fluid can be observed in acute lesions in the tendon sheet and even proliferated and vascularizated synovium [7] Injuries of the pulleys are frequently associated with flexor tendons lesions, as they form a functional unit. Using US the diagnosis of a pulley lesion is revealed during the examination with the finger in forced flexion and pressure towards the probe, permitting the evaluation of the distance between the tendon and the bone cortex [24,25]. If the distance is ≤2 mm or higher, but a single pulley ruptures, the patient should benefit from conservative therapy.…”

Ultrasonography in the diagnosis and management of non inflammatory conditions of the hand and wrist

et al. 2016

High resolution ultrasonography has already become an important tool in the diagnosis and management of inflammatory arthritis of the hand and wrist, but lately it has been proven to be the method of choice in the evaluation of traumatic lesions of tendons, annular pulleys, nerves, and ligaments and at the same time in detecting foreign bodies. The objective of this paper is to review and describe the current knowledge on these US findings and to highlight the ultrasonography role in the evaluation of non-inflammatory conditions of the hand and wrist.

“…Klauser et al (17) showed that patients with a tendon-phalanx distance of 0.3 cm at rest or 0.5 cm on dynamic images can be validly diagnosed with a pulley rupture. Diagnosis of the rupture is more easily made when the US is performed with forced flexion of the finger, i.e., active pressure of the finger towards the transducer (18,19).…”

Traumatic injuries of the wrist and hand are common. Ultrasonography (US) is a cost-effective, noninvasive, and effective imaging method for diagnosing traumatic lesions affecting the tendons, annular pulleys, ligaments, vessels, and nerves, and for detecting foreign bodies in the wrist and hand. The objective of this article was to review the main US findings of traumatic lesions in the wrist and hand.T he wrist and hand are the most important functional parts of the body in daily life activities and are prone to traumatic injuries. These injuries constitute 6.6% to 28.6% of all injuries and 28.0% of all musculoskeletal injuries (1, 2). According to Schoffl et al. (3), wrist and hand injuries account for 14.0% to 30.0% of all treated patients in emergency care. Although these injuries are not life-threatening, the accepted treatment strategy for traumatic injuries is immediate reconstruction of all injured tissue structures. Hence, early diagnosis of the injured tissue is important for clinical management.Current ultrasonography (US) systems equipped with linear-array transducers have improved the capability of US to examine superficial organs and tissues. As an easily accessible, rapid, noninvasive imaging technique that also provides dynamic examination, US is a good imaging modality for examining the musculoskeletal system (4, 5).The purpose of this article was to review the main US findings and discuss the potential value of this technique in the evaluation of traumatic injuries of the wrist and hand. US techniquesUsing proper US examination techniques based on a thorough knowledge of the relevant anatomy and artifacts is essential for accurate diagnosis. High-frequency linear-array transducers (7-15 MHz) are mandatory for the ultrasonographic evaluation of superficial structures. The wrist and hand are best examined with the patient seated in front of the examiner with the wrist and hand placed on a table. The transducer is held with the first three fingers, and the other fingers rest on the table to reduce contact pressure. The longitudinal axis is the principal axis and is essential for diagnosis, while the transverse images are used for support. A large amount of transmission jelly is required for good contact and near field resolution.

Value of Transducer Positions in the Measurement of Finger Flexor Tendon Thickness by Sonography

Abstract: Standardized transducer positions for sonographic measurements of finger flexor tendon thickness showed good interobserver and intraobserver variability. Position I was found to be more reliable than position II.
