Hand anatomy muscles

A brief description of the complex anatomy of the hand with emphasis given to the anatomic features amenable to US examination, including finger joints and ligament complexes, flexor and extensor tendons, intrinsic hand muscles and neurovascular structures is included here. 

Diagnosis of superficial lipomas is usually straightforward. In deep-seated or intramuscular masses, the identification of the lipomatous mass may be more difficult with US due to a similar appearance with adjacent muscles (Fig. 11.70). In such cases, a fidl knowledge of the muscular anatomy of the palm and the comparative evaluation of the opposite hand may be helpful for the conclusive diagnosis.
