| | Shoulder Rotator Cuff Disease |
| | The acromion forms the “ceiling” of the shoulder, serves as the point of origin for the deltoid muscle, and joins the clavicle (collarbone) to form the acromioclavicular (a/c) joint. | | | Therapy may include heat, cold, ultrasound, electrical stimulation, massage and other modalities, but the hallmark of an effective rotator cuff rehabilitation program is therapeutic exercise. | | | Rotator cuff repair is most commonly done by an open surgical procedure, which typically requires a 2 to 4 inch incision at the top of the shoulder. |

| | Impingement syndrome. Alphaklinik - The international specialists for knee, back and shoulder problems |
| | If the space available below the acromion is reduced, the pain becomes chronic, which also means that the dynamic balancing of the humeral head is compromised. | | | On the other hand, it is possible that the volume of soft tissue may increase (synovial bursa, tendons of the rotator cuff) underneath the bony acromion, which also leads to a mechanical conflict problem. | | | The mechanical attribute implies that all functional aspects are significant and must be taken into account and addressed within the scope of the physiotherapeutic treatment. |

| | shoulder case study |
| | With shoulder impingement, the space between the acromion and the head of the humerus is narrowed so that the tendon of the supraspinatus muscle rubs against the underside of the acromion. | | | The area between the acromion and greater tubercle is very tender and painful. | | | In the case of your patient, the shoulder impingement is not a result of any deformity of the acromion. |

| | Does Your Patient Really Need Acromioplasty? |
| | An important function of the anterior acromion and coracoacromial ligament is to act as a necessary passive stabilizer against superior migration of the humeral head. | | | A weakened supraspinatus then allows what is called "deltoid shear": the muscle imbalance between the supraspinatus and deltoid allows the deltoid to abnormally migrate the humeral head superiorly during shoulder elevation. | | | This theory is based on an extrinsic pathology, i.e., something outside the tendon is pressing on it. |

| | Background: In 1972, Neer first introduced the concept of rotator cuff impingement to the literature, stating that it results from mechanical impingement of the rotator cuff tendon beneath the anteroinferior portion of the acromion, especially when the shoulder is placed in the forward-flexed and internally rotated position. | | | As this condition progresses, it may lead to mechanical disruption of the rotator cuff tendon and to changes in the coracoacromial arch with osteophytosis along the anterior acromion. | | | A painful arc of motion may be experienced with elevation above the shoulder level in patients with impingement. |
