Below you will see a great tips with body part explained on rotator cuff
Damage to the rotator cuff muscle group is one of the most common causes of shoulder pain. Whether you are a throwing athlete, weight trainer, swimmer, physical, therapist or even office worker. Rotator cuff injuries are occurring more frequently. A normal functioning shoulder is essential for many tasks inside and out of the sporting world. Significant impairment of this mobile and highly functioning joint can impede greatly on the activities of daily living.
Functional Anatomy: The rotator cuff is a dynamic stabiliser of the humeral head by way of force couple relationship. This one pulls in a certain direction with other counterbalances.
The supraspinatus infraspinatus teres minor and subscapularis make up the rotator cuff. These muscles are considered to be a part of a cuff because the inserting tendons of each muscle blend or mould with and reinforce the glenohumeral capsule of the shoulder.
Nerve supply for the supraspinatus and infraspinatus is by the suprascapular nerve. The teres minor is supplied by the axillary nerve. The subscapularis the upper and lower subscapular nerve. The rotator cuff is a humeral head depressor and teares minor contributing. It balances shearing forces that are applied by larger prime moving muscles such as the deltoid and pectoralis. When the rotator cuff function is impaired the corresponding normal fulcrum of the humeral head is lost, causing an upward displacement and impingement of the subacromial structures and humeral head against the under surface of the acromion. A fulcrum is best described as the point or support on which a lever pivots.
Supraspinatus is the function of the supraspinatus is to act primarily as a stabilising compressor of the glenohumeral joint. It therefore creates a fulcrum for the deltoid to act much more efficiently. At the start of arm abduction from a neutral position, the supraspinatus is more important than the deltoid. The medial portion of the deltoid is of greater importance when the arm is elevated at higher anglesd.
What can go wrong for rotator cuff tears
The causes of rotator cuff tears are varied and likely a combination of age related degenerative change and micro or macro trauma. Smoking with high cholesterol and family history have also shown to predispose. Individual to tearing. Rotator cuff disruption may be characterised as partial or full tickness, chronic and traumatic or degenerative.
Treatment shoulder be considered in all patients with tendinitis. A different approach to conservative treatment is through active release techniques. Consider unique restrictions that occur in each shoulder injury as well as the impact those injuries have on other soft tissue structures along the entire kinetic chain of the shoulder. For rehabilitation should be gradual beginning with isometrics and gradually progressing through a strengthening program. For full thickness tears are surgically repaired by an orthopaedic surgeon, In younger and more active individual. Sporting athletes are certainly amongst this group and outcomes are usually good for appropriately selected patients. However with high quality evidence based on research is lacking to conclude what surgical treatments are superior or appropriate for a given patient.
