The patients demonstrated clinical evidence of chronic tendinitis of the supraspinatus muscle, some with calcifying tendinitis.
The suprascapular nerve contributes sensory fibres to the shoulder joint and provides motor innervation to the supraspinatus and infraspinatus muscles.
In cases of supraspinatus tendinitis, localization was achieved by inline ultrasound on the base of the tendon.
The intrinsic muscles of the scapula include the muscles of the rotator cuff- the subscapularis, teres minor, supraspinatus, and infraspinatus.
Another study suggested that shneck pain was in the nearby supraspinatus muscle and this resulted from a seemingly asymptomatic form of shoulder impingement.
The supraspinatus is most commonly involved in a rotator cuff tear.
It is in relation, above, in rare cases with the articular disk; below, with the tendon of the supraspinatus.
Microwave diathermy-induced hyperthermia produced short-term pain relief in established supraspinatus tendinopathy.
