“…High-frequency ultrasound is the most widely used method to directly observe the morphology of the peripheral nerve6. High-frequency ultrasound is noninvasive and easily accepted by patients, which is beneficial for multiple dynamic follow-ups after repair of the peripheral nerve.…”

This study aimed to observe the morphological characteristics of a PGLA [poly(glycolide-co-L-lactide)] nerve conduit and regenerated nerve bundle in the human body using high-frequency ultrasound and examine functional recovery of the regenerated nerve using functional magnetic resonance imaging (fMRI) after neural prosthesis with a PGLA nerve conduit. Thirty-nine patients underwent high-frequency ultrasound, and one patient with superficial radial nerve injury (27-mm defect) underwent fMRI at one, three, and six postoperative months. The fMRI examination results were compared with sensory detection and high-frequency ultrasound results during the same follow-up window period. The normal and regenerated nerve bundles had similar ultrasonic imaging features. At one postoperative month, fMRI displayed activeness of the normal cortex in the brain region corresponding to the contralateral superficial radial nerve, while no activeness was observed on the ipsilateral side. From three to six postoperative months, fMRI revealed gradually increasing activeness in the brain region corresponding to the ipsilateral superficial radial nerve, but the activation area on the ipsilateral side was smaller than that on the contralateral side. Combining morphological detection of the regenerated nerve using high-frequency ultrasound and functional detection of the regenerated nerve using fMRI may be a valuable method for evaluating repair of peripheral nerve injury.

“…Multiple studies correlating sonographic findings with surgical exploration have demonstrated the ability to distinguish between various types of nerve injury, ranging from simple contusions with fusiform thickening of the nerve to partial tears or complete lacerations. [6][7][8] This information has a profound impact for both the surgeon and the patient, as many humeral fractures are treated with closed reduction, with low rates of malunion, although there is a 10% to 32% risk of developing secondary radial nerve palsy with intervention. 9 As such, the decision to pursue surgical intervention for treatment of the nerve injury may be guided by the sonographic results.…”

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.
