    Abstract Objective: The aim of this article is to present the sonographic appearance of the most common masses of the wrist and hand and to discuss the role of sonography in their diagnosis.
    Conclusion: Sonography is a readily available imaging technique that can detect and assess masses of the wrist and hand. Together with standard radiography, sonography can be used as a first-line radiologic technique in this field.

    Abstract Ultrasonography in hand surgery offers the option of imaging trauma consequences or degenerative problems in the wrist and fingers, involving bones, joints, ligaments, tendons, annular pulley, carpal and digital changes, soft masses, and foreign bodies including dynamic changes during motion. In the hands of the treating surgeon, ultrasonography allows immediately to plan conservative treatment versus surgery, to precisely infiltrate joints or tendon spaces as well as to perform miniinvasive assisted surgery.

    Abstract This study investigated the sensitivity, specificity, and accuracy of physical examination compared with high resolution sonography for the detection of the palmaris longus tendon in 136 wrists. The incidence of tendon absence was 10% by sonography and 14% by physical examination. The sensitivity of the physical examination was 94% and the specificity 86% compared with sonography as the reference standard. Accurate identification of the palmaris longus tendon through physical examination was not influenced by body mass index or wrist circumference. Upon review of the sonography images, none of the palmaris longus tendons missed on physical examination were considered to be adequate for grafting based on expert opinion. While physical exam was 93% accurate for detection of the palmaris longus tendon compared with ultrasound, our study suggests that it is sufficient for detection of those tendons that can be used as donors clinically.

    Abstract Although the anatomy of the hand and wrist is complex and the pathologic conditions encountered are diverse, many of the disease processes are localized, and in many situations, the clinical question is specific and limited. Because of this, ultrasound has always been an attractive imaging modality for evaluation of hand and wrist problems. Unfortunately, intrinsic difficulties in ultrasound image acquisition and interpretation have slowed the acceptance of hand and wrist sonography. Recently, however, new developments in high-resolution transducers and signal processing have dramatically improved image quality and scanning flexibility. For this reason, hand and wrist sonography is now more widely accepted and is taking its place along side other traditional modalities such as radiography, computed tomography, magnetic resonance imaging, and arthrography. Specific situations in which ultrasound offers definite benefits include evaluation of tendon inflammation and rupture, evaluation of palpable masses or suspected occult masses, and evaluation of suspected foreign bodies. Analysis of the median nerve is also possible and in the future, may have a role in patients with carpal tunnel syndrome.

    Abstract With the advent of new technical improvements and innovations, sonography is gaining ground in use and acceptance as a highly useful modality to diagnose a variety of diseases involving the wrist and the hand. Common ailments such as tendinitis and tenosynovitis can be diagnosed easily, and the diagnosis of small soft tissue masses such as ganglia has become almost routine. Sonography holds great promise in the evaluation of disease involving the median and the ulnar nerves, the ligaments of the wrist, and the triangular fibrocartilage. It is the ideal modality in the diagnosis of intra-articular loose bodies.

    Abstract Purpose: To determine whether sonography can be an alternative method to nerve conduction study (NCS) in the diagnosis of carpal tunnel syndrome (CTS), by comparing sonography with nerve conduction study using clinical diagnosis as the reference standard.
    Methods: Forty-one wrists of 29 patients were enrolled, along with the same number of age- and gender-matched controls. All patients had sonographic measurement of the cross-sectional area (CSA) of the median nerve and NCS. Sensitivity and specificity were obtained and compared between sonography and NCS.
    Results: There were no significant differences in age, gender, body mass index and involved side between patients and controls (p<.05). The CSA at the tunnel inlet was significantly larger in patients than in controls (p=.03). The best cutoff value of CSA at the tunnel inlet was 10.7 mm(2), which had a sensitivity of 66% and a specificity of 63%. NCS showed a sensitivity of 78% and a specificity of 83%. Sensitivity was similar between sonography and NCS (p=0.27), whereas specificity was significantly lower in sonography than in NCS (p=0.02).
    Conclusions: Sonography is not accurate enough to replace NCS for the diagnosis of CTS.

    Abstract The radial artery as a superficial structure at the wrist is susceptible both to direct penetrating injury and to blunt trauma, with the potential development of both false and true aneurysms. This report summarizes the sonographic features of seven consecutive patients who were referred for evaluation of the radial artery. The diagnoses include two cases of radial artery aneurysm, one tortuous nonaneurysmal artery, two cases of arteriovenous fistulae (one surrounded by fluid and one aneurysmal), a ganglion, and an inflammatory mass of the wrist. Although radial aneurysms are unusual and angiography may be required to define the nature and extent of distal embolization to the hand, the nature of a palpable aneurysm in this region, vascular vs avascular, is easily and quickly assessed with high-resolution sonography.

    Abstract Background: The purpose of our study was to explore the sonographic characteristics of fibromas of the tendon sheath of the hand and wrist and to evaluate the value of high frequency ultrasound in the diagnosis of FTS.
    Methods: We retrospectively reviewed the sonography of 42 patients with surgically proven FTS, including one with a relapsing tumor (43 lesions in total). The location, size, distribution, relationship with the surrounding tissue, two-dimensional gray-scale sonographic appearance and internal color blood flow of all lesions were analysed.
    Results: The maximum diameter ranged from 0.4 to 2.8 cm, with an average of 1.5 ± 0.6 cm. Twenty-eight lesions (65%) were associated with an adjacent tendon, while the other 15 lesions (35%) were next to the joint. Spindle or oval lesions were common, followed by irregular shape. The nodules with clear boundaries were hypoechoic and had posterior echo enhancement. Thirty-seven lesions (86%) were homogeneous, while 6 lesions (14%) had cystic components with no echo inside. Seventeen lesions (40%) had a large amount of blood flow. Nine lesions (20%) had a small amount of blood flow. The other 17 lesions (40%) had no significant blood flow.
    Conclusions: The diagnosis of fibroma of the tendon sheath can be considered when ultrasound examination reveals a focal nodular mass adjacent to a tendon sheath with homogeneous hypoechogenicity and no or small or large amounts of blood flow.

    Abstract A 60-year-old man presented with focal swelling on the dorsal surface of the left wrist. The sonographic exam revealed the presence of a smoothly rounded hypoechoic mass, with internal blood flow in the lumen of the vein. The histopathological findings led to the diagnosis of intravenous lobular capillary hemangioma (LCH). Here, we reported an intravenous LCH arising from the cephalic vein on the dorsal surface of the left wrist hand and discussed the related ultrasonographic findings.
