Dealing With TMJ Pain
Sometimes, a narrow space for passage of tendon Joint
Complex 4000 Review underneath the acromion can result in direct mechanical abrasion of the tendon. This has been termed outlet impingement and is commonly referred to as impingement syndrome. A prominent acromial spur and thickened bursal tissue in the subacromial space can abrade the tendon running underneath.
How does a torn rotator cuff occur in athletes?Damage and ultimately tearing of the rotator cuff tendons has been attributed to either static or dynamic causes. Static changes refer to impingement and mechanical abrasion of the tendons from narrowing of the subacromial space, most commonly due to roughness or "spurring" on the underside of the acromion or thickening of the coracoacromial ligament.
On the other hand, a torn rotator cuff can result from abnormal dynamic motion of the humeral head and cuff relative to scapula, leading to abnormal strain on the tendon and tearing on either the joint or bursal side. For example, muscle weakness can allow the humeral head to rise higher towards the acromion and is considered to be one of the most common dynamic causes of a torn rotator cuff in athletes.
A torn rotator cuff result when the muscles and tendons of the rotator cuff become frayed under the acromion bone of the shoulder. This occurs both with aging as well as in younger people who perform repetitive overhead activities. Baseball pitchers as well as occupations that require overhead work are two examples of people at risk of sustaining rotator cuff tears. Pedro Martinez and Randy Johnson are both examples of professional, hall-of-fame bound pitchers who developed this injury.
