Hypothenar hammer syndrome is observed in some occupational groups or some athletes who use objects that can cause recurrent trauma to the superficial palmar region of their ulnar artery by the object they handle. The advance in imaging technologies and the increased use of these methods significantly raised the importance of MRI as well as MR angiography in evaluating wrist pathologies. Presenting these cases we aimed to discuss the MR imaging findings of hypothenar hammer syndrome. HHS is a treatable and preventable cause of the upper extremity digital ischemia. Radiologists should keep HHS in mind as a differential in the cases presenting with hand and finger symptoms, especially the ones in risk groups.

This paper is about a posttraumatic distal ulnar artery thrombosis case that has occurred after a single blunt trauma. The ulnar artery thrombosis because of chronic trauma is a frequent condition (hypothenar hammer syndrome) but an ulnar artery thrombosis because of a single direct blunt trauma is rare. Our patient who has been affected by a single blunt trauma to his hand and developed ulnar artery thrombosis has been treated by resection of the thrombosed ulnar artery segment. This report shows that a single blunt trauma can cause distal ulnar artery thrombosis in the hand and it can be treated merely by thrombosed segment resection in suitable cases.

“…Traumatic (penetrating, blunt, or iatrogenic) and occupational (e.g., hypothenar hammer syndrome or the use of vibratory tools) factors may cause thrombosis in the ulnar and radial arteries (30,32). Thrombosis of a vessel is seen as an iso-hyperechoic structure filling the lumen on gray-scale US.…”

“…Thrombosis of the distal upper extremity arteries is uncommon and occurs most often on the ulnar side (32). Traumatic (penetrating, blunt, or iatrogenic) and occupational (e.g., hypothenar hammer syndrome or the use of vibratory tools) factors may cause thrombosis in the ulnar and radial arteries (30,32).…”

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.
