Ultrasound of the hand

Abstract

A recent development of high resolution transducers has increased the possibility to evaluate the most superficial body structures. The assessment of the normal anatomy and of the pathological changes of the hand and the wrist has become popular among musculoskeletal sonologists and nowadays ultrasound is considered one of the first line imaging techniques in the assessment of this district. Ultrasound must always be performed after a standard radiograph since the association of the two techniques can diagnose a wide variety of disorders. Some lesions however cannot be detected and require more invasive and expensive modalities (CT, MRI, CT and MRI arthrography). The goal of this article is to present the ultrasound appearance of inflammatory and traumatic diseases of the hand and wrist as well as the findings in entrapment neuropathies and soft tissue tumors.
