Ultrasound of the elbow

Ultrasonography (US) is an efficient alternative to magnetic resonance (MR) imaging for evaluation of soft tissues of the elbow. US is able to diagnos e several abnormalities affecting tendons, muscles, ligaments and bursae ar ound the elbow joint. In cubital tunnel syndrome, US identifies ulnar nerve abnormalities and extrinsic lesions that may cause nerve entrapment. Occul t fractures, osteophytes and intraarticular loose bodies can also be imaged . In para-articular swelling, US is able to assess the presence of capsular and synovial processes and to differentiate them from soft tissue tumors. Key advantages of this technique include cost-effectiveness, availability a nd ability to perform a dynamic examination.
