   Introduction Top

High resolution ultrasound of the tendons has become a very rewarding technique to diagnose common and uncommon disorders of these structures. Due to the superficial location of the majority of the tendons, they are easily approached by the transducer. Further ultrasound guided biopsy can be done if necessary. Comparative study with normal side, dynamic scanning and graded compression technique can be used to provide additional information. This technique is however limited by presence of artifacts like tendon anisotropy.

   Materials and methods Top

This was a retrospective study of 40 cases, done at Dr D.Y. Patil Hospital, Medical College and Research Centre, Pimpri.

Ultrasound scanner used was GE Logiq 400 PRO Series with 11 MHz linear transducer.

   Pictorial presentation of cases Top

A pictorial presentation of few of the characteristic cases is presented.

   Discussion Top

Tendons are composed largely of parallel running fascicles of collagen fibers that inter weave and inter connect [1]. On ultrasound tendons are seen to be echogenic with a characteristic fibrillary echotexture [2]. Surrounding the tendon is either an epitendineum or a synovial sheath. The synovial sheath contains a thin film of fluid that serves as a lubricant to tendons. Without a synovial sheath, the epitendineum, a dense connective tissue layer, is tightly bound to the tendon. Sonographically the epitendineum is seen as a reflective line surrounding the tendon. [3]

Acute tendonitis is detected by increased fluid within the synovial sheath. This increased fluid is seen as an anechoic halo around the tendon on transverse scans.

Chronic tendinitis is seen as thickening of the tendon itself without increase in the synovial fluid. Comparison with opposite side is essential to make a diagnosis of chronic tendonitis [1],[4],[ 5].

Tenosynovitis is inflammation of tendon sheaths. It can be caused by trauma, pyogenic infection or rheumatoid arthritis [6].

Ganglia are the most common swelling in the hand. These are cystic lesions arising from synovial lining of joint or tendon sheath [7].
