In the recent years US has gained wide diffusion as a useful imaging tool in the evaluation of musculoskeletal disorders. Recognized advantages of US over the other imaging modalities are low costs, non-invasiveness, possibility to perform a dynamic examination and readiness. Unfortunately, US has a long learning curve and allows good results only when performed by well-trained and experienced examiners. Specifically, utilization of the recent small transducers allows to perform dynamic examination of the hand during flexion-extension movements of the fingers, while their high frequency (till 15 MHz) have increased the possibility to evaluate small anatomic structures of the hand and wrist as well as to detect subtle pathologic changes. The purpose of this article is to present first the normal basic anatomy and US appearance. Then the main pathological conditions including joint and tendon disorders, foreign bodies and other traumatic lesions, entrapment neuropathies and expansible lesions will be presented.

Abstract
In the recent years US has gained wide diffusion as a useful imaging tool in the evaluation of musculoskeletal disorders. Recognized advantages of US over the other imaging modalities are low costs, non-invasiveness, possibility to perform a dynamic examination and readiness. Unfortunately, US has a long learning curve and allows good results only when performed by well-trained and experienced examiners. Specifically, utilization of the recent small transducers allows to perform dynamic examination of the hand during flexion-extension movements of the fingers, while their high frequency (till 15 MHz) have increased the possibility to evaluate small anatomic structures of the hand and wrist as well as to detect subtle pathologic changes. The purpose of this article is to present first the normal basic anatomy and US appearance. Then the main pathological conditions including joint and tendon disorders, foreign bodies and other traumatic lesions, entrapment neuropathies and expansible lesions will be presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
