[Topographic anatomic features of radiocarpal joints and carpal articulations].

Ultrasound study of the musculoskeletal system has become one of the new areas in the development of echography. This radiation diagnostic technique allows evaluation of the status of soft tissue and cartilaginous components of the joint with a high precision. Knowledge of the echoanatomy of upper limb diarthrosis makes it possible to detect abnormalitles in due time and to specify their nature.
