TL;DR: The shoulders in which the repaired cuff was intact at the time of follow-up had better function during activities of daily living and a better range of active flexion compared with the shoulders that had a large recurrent defect.
Abstract: We evaluated the results of 105 operative repairs of tears of the rotator cuff of the shoulder in eighty-nine patients at an average of five years postoperatively. We correlated the functional result with the integrity of the cuff, as determined by ultrasonography. Eighty per cent of the repairs of a tear involving only the supraspinatus tendon were intact at the time of the most recent follow-up, while more than 50 per cent of the repairs of a tear involving more than the supraspinatus tendon had a recurrent defect. Older patients and patients in whom a larger tear had been repaired had a greater prevalence of recurrent defects. At the time of the most recent follow-up, most of the patients were more comfortable and were satisfied with the result of the repair, even when they had sonographic evidence of a recurrent defect. The shoulders in which the repaired cuff was intact at the time of follow-up had better function during activities of daily living and a better range of active flexion (129 +/- 20 degrees compared with 71 +/- 41 degrees) compared with the shoulders that had a large recurrent defect. Similar correlations were noted for the range of active external and internal rotation and for strength of flexion, abduction, and internal rotation. In the shoulders in which the cuff was not intact, the degree of functional loss was related to the size of the recurrent defect.(ABSTRACT TRUNCATED AT 250 WORDS)

TL;DR: In this article, an open thoracotomy surgical technique for aortic valve replacement is disclosed, where a surgical incision (200) is made in one of several locations such as a midline sternotomy incision, a small anterior right or left thoracotomies, a posterior thoracomas, a suprasternal supra-clavicle approach, or through port sites (mini incisions) over the chest wall.
Abstract: An open thoracotomy surgical technique for aortic valve replacement is disclosed. A surgical incision (200) is made in one of several locations such as a midline sternotomy incision, a small anterior right or left thoracotomy, a mini-thoracotomy, a posterior thoracotomy, a suprasternal supra-clavicle approach, or through port sites (mini incisions) over the chest wall. The pericardium is then opened. The faulty natural aortic valve, next to the left ventricle (2), is excised and removed. A fastener driving tool with a cuff (19) attached is inserted through the incision (200). The knob (36) is rotated while holding handle (35) to deploy the fasteners through the cuff (19) to secure it. Finally, a prosthesis valve body (20) is attached to the cuff (19) before closing the incision (200).

TL;DR: Two hundred twenty shoulders with a rotator cuff tear repaired by simple tendon-to-bone suture were analyzed to determine whether the severity of presurgical fatty degeneration had an influence on their anatomic and functional outcome.

TL;DR: There is a high correlation between the onset of rotator cuff tears (either partial or full thickness) and increasing age, and surveillance at yearly intervals is recommended for patients with known rotators cuff tears that are treated nonoperatively.
Abstract: Background: Very little comparative information is available regarding the demographic and morphological characteristics of asymptomatic and symptomatic rotator cuff tears. This information is important to provide insight into the natural history of rotator cuff disease and to identify which factors may be important in the development of pain. The purpose of the present study was to compare the morphological characteristics and prevalences of asymptomatic and symptomatic rotator cuff disease in patients who presented with unilateral shoulder pain.
Methods: Five hundred and eighty-eight consecutive patients in whom a standardized ultrasonographic study had been performed by an experienced radiologist for the assessment of unilateral shoulder pain were evaluated with regard to the presence and size of rotator cuff tears in each shoulder. The demographic factors that were analyzed included age, gender, side, and cuff thickness. All of these factors were evaluated with regard to their correlation with the presence of pain.
Results: Of the 588 consecutive patients who met the inclusion criteria, 212 had an intact rotator cuff bilaterally, 199 had a unilateral rotator cuff tear (either partial or full thickness), and 177 had a bilateral tear (either partial or full thickness). The presence of rotator cuff disease was highly correlated with age. The average age was 48.7 years for patients with no rotator cuff tear, 58.7 years for those with a unilateral tear, and 67.8 years for those with a bilateral tear. Logistic regression analysis indicated a 50% likelihood of a bilateral tear after the age of sixty-six years (p < 0.01). In patients with a bilateral rotator cuff tear in whom one tear was symptomatic and the other tear was asymptomatic, the symptomatic tear was significantly larger (p < 0.01). The average size of a symptomatic tear was 30% greater than that of an asymptomatic tear. Overall, patients who presented with a full-thickness symptomatic tear had a 35.5% prevalence of a full-thickness tear on the contralateral side.
Conclusions: There is a high correlation between the onset of rotator cuff tears (either partial or full thickness) and increasing age. Bilateral rotator cuff disease, either symptomatic or asymptomatic, is common in patients who present with unilateral symptomatic disease. As the size of a tear appears to be an important factor in the development of symptoms, we recommend surveillance at yearly intervals for patients with known rotator cuff tears that are treated nonoperatively.

TL;DR: It is proposed that the following pathogenetic mechanisms are responsible for the progressive roentgenographic changes: arm elevation in activities of daily living, rupture of the long head of biceps tendon, the abnormal fulcrum of the humeral head against the acromion and the coracoacromial ligament, and the weakness of external rotation.
Abstract: It is difficult to determine the size and localization of rotator cuff tears preoperatively. But with the special arthrographic technique, a diagnosis with about 80% accuracy was possible in 65 surgically confirmed rotator cuff tears. With this technique, 22 massive cuff tears were found in conservatively treated patients. In these patients, the plain roentgenograms obtained at the initial examination were also analyzed. The roentgenographic findings included narrowing of the acromiohumeral interval and degenerative changes of the humeral head, the tuberosities, the acromion, the acromioclavicular joint, and the glenohumeral joint. Based on these data, five roentgenographic grades of massive cuff tears were identified. Of seven patients with massive tears, which had been treated conservatively and followed for more than eight years, the roentgenographic grades advanced in five. One shoulder progressed to cuff-tear arthropathy. Based on these observations, it is proposed that the following pathogenetic mechanisms are responsible for the progressive roentgenographic changes: (1) arm elevation in activities of daily living, (2) rupture of the long head of biceps tendon, (3) the abnormal fulcrum of the humeral head against the acromion and the coracoacromial ligament, and (4) the weakness of external rotation. A massive cuff tear will progress to cuff-tear arthropathy, with each step of progression accompanied by characteristic roentgenographic changes.
