THE EFFECT OF ULTRASOUND GUIDED PLATELET RICH PLASMA (PRP) INJECTION IN THE NON-SURGICAL TREATMENT OF PARTIAL SUPRASPINATUS TENDON TEAR

Abstract

• The rotator cuff is a group of four muscles and their tendons, important in stabilizing the glenohumeral joint: supraspinatus, infraspinatus, teres minor and subscapularis.

• Rotator cuff tears are the most common cause of shoulder disability with their prevalence ranging from 20 to 40% in the aging population. Degenerative changes and inflammation in the supraspinatous tendon is the most important causes of rotator cuff and shoulder pain. Muscular weakness and reduced mobility are common symptoms. Such pain and dysfunction are refractory to usual treatments and have become a challenge for physicians as to date; there is no gold standard treatment.

• The most common risk factor of supraspinatous tendinosis and partial tear were repetitive lifting and overhead activities especially in old age and overweight. Traumatic injury are much less.

• The rotator cuff is limited in its ability to regenerate due to poor vascularization of the tendon tissue.
