Abstract:

Background: Partial-thickness rotator cuff tears are common shoulder injuries in baseball players. For some tears, the symptoms can be relieved through physical therapy or debridement without rotator cuff repair. Purpose: To assess whether partial-thickness rotator cuff tear by itself causes shoulder pain and muscle weakness in baseball players. Study Design: Cross-sectional study; Level of evidence, 3. Methods: We studied 87 university baseball players (age, 19.5 ± 0.8 years; baseball career, 11.5 ± 1.6 years). All data were obtained during a full-participation annual medical check in 1 team.

Objective: This study aims to comprehensively explore the association between different types and locations of supraspinatus tendon tears and the presence of humeral head bone cysts. Specifically, the study seeks to investigate how the location and grade of supraspinatus tears, as classified by the Elmann system, correlate with the occurrence, size, and distribution of humeral cysts. Additionally, the study examines the relationship between tear dimensions (measured anteroposteriorly), the presence of joint and subacromial fluid, and the anatomical localization of the tears (footprint, critica

Abstract:

Objectives: Rotator cuff tears are common shoulder injuries in baseball players. In some severe tears (i.e. through more than 50% of the cuff’s thickness), conservative treatment does not work well, and surgical treatment is sometimes chosen in an effort to ensure return to play. In contrast, some partial thickness rotator cuff tears do not cause shoulder symptoms, even during throwing motion. The objective of this study was to assess whether partial thickness rotator cuff tears cause shoulder pain and muscle weakness in baseball players.

Abstract Rotator cuff tear is highly prevalent in older adults, with supraspinatus tendon tear (STT) the most common. Shoulder rehabilitation is a major treatment strategy, but supraspinatus-muscle-fatty infiltration (FI) and shoulder function in older adults with rotator cuff tear primarily managed by physical therapy (PT) is inadequately documented.

Background: Degenerative and traumatic changes to the rotator cuff can result in massive and irreparable rotator cuff tears (RCTs). Purpose/Hypothesis: The study objective was to conduct a biomechanical comparison between a small, incomplete RCT and a large, complete RCT. We hypothesized that the incomplete supraspinatus (SS) tear would lead to an incremental loss of abduction force and preserve vertical position of the humeral head, while a complete SS tear would cause superior humeral migration, decrease functional deltoid abduction force, and increase passive range of motion (ROM).

Abstract:

Objectives: While rotator cuff tears often require repair of the supraspinatus, patients can also have a concurrent tear of the subscapularis requiring repair. Previous smaller studies have shown good clinical outcomes following the repair of the subscapularis and rotator cuff during the same procedure.1 The purpose of this study was to compare clinical outcome measures between patients who had isolated supraspinatus repairs versus those who had a supraspinatus tear with a concurrent subscapularis repair.

Background: Coracoacromial ligament (CAL) degeneration is thought to be a factor in external impingement in bursal-sided rotator cuff tears, but CAL release is associated with adverse effects.

Abstract:

The success of rotator cuff tendon repair relies on both tendon healing and muscle recovery. The objective of this descriptive study was to investigate the regenerative potential of the supraspinatus muscle in rotator cuff tear conditions by quantifying the expression of Pax7, MyoD, and myogenin, basic factors that regulate myogenesis. Muscle biopsies were collected from thirty-three patients aged 34 to 73 years who underwent surgery for a rotator cuff tear affecting the supraspinatus muscle. Among these patients, twenty-seven percent were women, and the age of the lesions ranged from 2 to 72

To document the incidence of asymptomatic rotator cuff tears in patients with a confirmed symptomatic tear in the opposite shoulder, and to identify ultrasound findings that may distinguish symptomatic from asymptomatic tears.

Abstract:

Magnetic Resonance Imaging (MRI) is a diagnostic examination modality in medical science using a magnetic field without using X-rays. MRI has the advantage of being able to create images and showing clearer and more sensitive anatomical differences in soft tissues in the body such as the extremities, brain, bone marrow and musculoskeletal to establish a clinical diagnosis, one of which is Supraspinatus Injury to the Shoulder. Supraspinatus is a tear or rupture of the tendon of the supraspinatus muscle. The supraspinatus is part of the shoulder rotator cuff. Most of the time, it is accompanied

Background: Massive rotator cuff tears (RCTs) begin as primary tendon injuries and cause a myriad of changes in the muscle, including atrophy, fatty infiltration (FI), and fibrosis. However, it is unclear which changes are most closely associated with muscle function. Purpose: To determine if FI of the supraspinatus muscle after acute RCT relates to short-term changes in muscle function. Study Design: Controlled laboratory study. Methods: Unilateral RCTs were induced in female rabbits via tenotomy of the supraspinatus and infraspinatus. Maximal isometric force and rate of fatigue were measured

Summary. Bone density is an important factor that affects the strength of the suture of the tendons of the rotator cuff. The higher the bone density is, the greater is the strength of fixation of the supraspinatus tendon to the bone, since the anchor is more securely fixed in the bone. Objective: to determine the bone mineral density of the proximal humeral epiphysis in patients with partial tear of the supraspinatus tendon. Materials and Methods.

Supraspinatus tendon tears are common and lead to changes in the muscle architecture. To date, these changes have not been investigated for the distinct regions and parts of the pathologic supraspinatus. The purpose of this study was to create a novel three-dimensional (3D) model of the muscle architecture throughout the supraspinatus and to compare the architecture between muscle regions and parts in relation to tear severity. Twelve cadaveric specimens with varying degrees of tendon tears were used. Three-dimensional coordinates of fiber bundles were collectedin situusing serial dissection a

The pathogenesis of subacromial impingement syndrome is controversially discussed. Assuming that bursal sided partial tears of the supraspinatus tendons are rather the result of a direct subacromial impact, the question arises whether there is a morphological risk configuration of the acromion and its spatial relation to the glenoid. Patients who underwent arthroscopic repair of either a partial articular supraspinatus tendon avulsion (PASTA) or bursal-sided supraspinatus tear (BURSA) were retrospectively allocated to two groups.

An intratendinous cyst of the long head of the biceps tendon is a very rare form of cystic lesion. This type of cyst was discovered in a patient along with a partial tear of the supraspinatus tendon, supraspinatus tendinopathy, subacromial-subdeltoid bursitis, and sheath effusion of the long head of the biceps tendon. Degeneration may have been the cause of this intratendinous cyst.
