BACKGROUND: The long-term outcome after the treatment of subacromial impingement syndrome (SAIS) with either nonsurgical or surgical methods has not been thoroughly investigated. Hypothesis/Purpose: The purpose was to evaluate the long-term clinical outcome and the presence of rotator cuff injuries and osteoarthritis (OA) after the surgical and nonsurgical treatment of SAIS. The hypothesis was that, at a minimum 10 years after the initial treatment, patients who had undergone acromioplasty would have a better clinical outcome and run a lower risk of developing rotator cuff ruptures and OA as compared with those treated with physical therapy...

CASE: A 9-year-old boy sustained intrasubstance tears of the rotator cuff and periscapular muscles due to a fall, resulting in scapular winging and severely decreased shoulder range of motion. Treatment consisted of a modified thoracolumbosacral orthosis (TLSO) with a shoulder immobilizer attachment (to reduce the scapula to the thoracic wall and hold the arm in 10° of abduction). The brace was worn for 8 weeks. The patient recovered full, pain-free shoulder function and range of motion, and returned to high-level athletics...

Tendons and ligaments are dense fibrous connective tissues mainly composed of type I collagen, aligned in highly ordered arrays along the axis of the tendon and ligament. The enthesis is defined as the attachment site of a tendon, ligament, joint capsule, or fascia to bone. During morphogenesis, the cell population co-expressing Scleraxis(Scx)and the SRY-box containing gene 9(Sox9)contributes to the formation of fibrocartilaginous entheses. Scx regulates tendon and ligament maturation, while Sox9 is a key regulatory factor for cartilage formation...

BACKGROUND: Studies have demonstrated radiographic findings of sclerosis and cortical irregularity at the greater tuberosity can suggest a rotator cuff tear. Plain radiographs are the most easily attainable first-line investigations in evaluating shoulder injuries. This study determines the effectiveness in predicting degenerate rotator cuff tears by detecting radiographic changes on shoulder x-rays. METHODS: Retrospective cross-sectional study with a consecutive series of patients conducted in Hinchingbrooke Hospital, Huntingdon, United Kingdom from January 2015 to June 2017...

BACKGROUND: Although sports participation and heavy physical work can contribute to rotator cuff tears, many patients expect to return to these activities after surgery; however, irreparable rotator cuff tears can preclude this outcome. A new surgical treatment-arthroscopic superior capsule reconstruction (SCR)-restores shoulder stability and muscle balance in patients with irreparable rotator cuff tears; consequently, it improves shoulder function and relieves pain. PURPOSE: To evaluate the rates of return to sports and physical work among patients treated with arthroscopic SCR...

BACKGROUND: The prevalence and severity of concomitant rotator cuff pathology in the setting of proximal biceps tendon ruptures are poorly understood. Concomitant rotator cuff disease may have important implications in the prognosis and natural history of this shoulder condition. Therefore, an observational cohort of patients with an acute rupture of the long head of the biceps tendon (LHBT) was evaluated to determine the prevalence and severity of concomitant rotator cuff disease. METHODS: Thirty consecutive patients diagnosed with acute proximal biceps tendon rupture were prospectively enrolled...

BACKGROUND: Neurologic pre- and postoperative injuries to the axillary and/or suprascapular nerve (SSN) have a higher incidence than expected and may lead to significantly decreased functional outcomes and increased risk of reverse shoulder arthroplasty (RSA) failure. METHODS: Patients who underwent a RSA for rotator cuff tear arthropathy (RCTA) were included from December 2014 to December 2015. This study focused on the clinical (Constant score), radiographic, and pre- and postoperative electromyographic evaluations at 3 and 6 months...

AIM: Arthrodesis of the shoulder joint is a radical event, so it is difficult to explain its significance to patients. It has been the last resort in hopeless cases. Knowledge of long-term results and evaluation of advantages and disadvantages seems to be helpful in this regard. METHODS: Eleven patients with mean age of 45 (31 - 58) years were operated between 2000 and 2013. All patients could be included in the investigation (FU mean 8.5 [3 - 16] years; 8 male and 3 female; right 9, left 2)...

The greater tuberosity is an important anatomic structure and its integrity is important for shoulder abduction and external rotation. Isolated fractures of the greater tuberosity are often subtle and may not be detected on initial radiographs. Clinically, these patients display symptoms which mimic a full thickness rotator cuff tear. It is important to differentiate these two entities, as their treatment is different (typically nonsurgical management for minimally displaced fractures versus rotator cuff repair for acute full thickness rotator cuff tears)...

To this day, how shoulder muscles react to a strong fatigue stimulus during dynamic shoulder rotations remains unknown. The aims of this study were to assess the effect of repeated maximal internal-external isokinetic shoulder rotations on shoulder strength and muscle activity. Twenty-four individuals completed a 50-repetition fatiguing isokinetic protocol while electromyography was recorded on eleven muscles of the shoulder girdle. Time-frequency transformation and an ANOVA model using statistical parametric mapping methods were used to analyze shifts in instantaneous median frequency (MDF) between each 10-repetition Blocks...

Tendinopathy is a significant clinical problem thought to be associated with altered mechanical loading. Explant culture models allow researchers to alter mechanical loading in a controlled in vitro environment while maintaining tenocytes in their native matrix. However, current models do not accurately represent commonly injured tendons, ignoring contributions of associated musculature and bone, as well as regional collagen structure. This study details the characterization of a mouse rotator cuff explant culture model, including bone, tendon, and muscle (BTM)...

BACKGROUND: Rotator cuff tears are rare injuries in adolescents but cause significant morbidity if unrecognized. Previous literature on rotator cuff repairs in adolescents is limited to small case series, with few data to guide treatment. HYPOTHESIS: Adolescent patients would have excellent functional outcome scores and return to the same level of sports participation after rotator cuff repair but would have some difficulty with returning to overhead sports. STUDY DESIGN: Case series; Level of evidence 4...

BACKGROUND: We investigated the impact of poor seated posture on the prevalence of rotator cuff tears (RCTs) among wheelchair-dependent individuals with long-standing paraplegia. METHODS: The study included 319 patients. Lateral radiographs of the spine were collected from a database and analyzed to assess the global spinopelvic alignment (SPA). Magnetic resonance images of both shoulders were obtained to detect the presence of cuff tears. Patients were divided into 2 groups: Group RCT-I included all patients with cuff tears (right, left, or bilateral), whereas group RCT-II consisted exclusively of patients with bilateral cuff tears...

With a range of tear characteristics such as chronicity, degree of fatty atrophy, and number of tendons involved as well as varying patient-specific characteristics including age, injury mechanism, and expectations after treatment to consider, proper and successful treatment of a rotator cuff tear is multifactorial and, consequently, challenging. Although conservative management of a rotator cuff tear may be successful, a more severe tear with involvement of more tendons may warrant surgical intervention. Furthermore, additional pathology including biceps tendinopathy may result in greater patient morbidity and an even more complex treatment decision-making process and surgical technique...

The majority of musculoskeletal injuries located in the shoulder are often due to repetitive or sustained movements that occur in work routines in different areas. In the case of musicians, such as violinists, who have long and daily training routines, the repetitive movements they perform are forced and sometimes the postures are not natural. Therefore, this article aims to study and simulate the dynamic behavior of the glenohumeral joint under repetitive conditions that represent the different postures assumed by a violinist during his daily training...
