For anatomical restoration of a repaired rotator cuff, mechanical augmentation of the repaired structure is essential. Using histological and biomechanical evaluation in a rat model, the authors sought to determine the efficacy of an absorbable alginate sheet at the supraspinatus tendon-to-bone repair site for healing of the rotator cuff tear. Forty adult (12 weeks old) male Sprague- Dawley wild-type rats were used in this study. Read More

Rotator cuff tears are frequently treated in daily clinical practice. However, there have been few reports of tears around the shoulder involving the latissimus dorsi and teres major muscles. The author reports the rare case of an isolated tear of the teres major muscle with symptom onset during ordinary sports activities without a clear traumatic mechanism. Read More

Case: A 49-year-old man presented with apprehension of a repeat dislocation after a left shoulder dislocation, which was accompanied by pain and restricted active range of motion of the shoulder. We performed an arthroscopic Bankart repair as well as an arthroscopic superior capsular reconstruction (ASCR) with fascia lata for the irreparable massive rotator cuff tear. Two years postoperatively, there was no shoulder pain or repeat dislocation; the range of motion had improved. Read More

Introduction: The accuracy of MRI for subscapularis tear is lower than that of overall rotator cuff tears. Until now, no systematic reviews and meta-analysis have been conducted to compile these data. The purpose of this study was to determine, through a systematic review and meta-analysis, the diagnostic accuracy of MRI in the detection of subscapularis tendon tears. Read More

Aim: Pulsed radiofrequency (PRF) therapy has become increasingly popular in the treatment of chronic shoulder pain due to its long duration of action and non-destructive method. The aim of the study was to reveal the effects of PRF therapy of the suprascapular nerve (SSN) under ultrasound guidance (UG) in patients with chronic shoulder pain on both shoulder pain and function.

Material And Methods: This study included 74 patients diagnosed with at least one of the following: adhesive capsulitis, rotator cuff syndrome and impingement syndrome of shoulder. Read More

Background: Rotator cuff disease has a high prevalence and is associated with shoulder pain and disability. Dyslipidemia might be an intrinsic factor related to the development of the disease as it might increase tendon stiffness and result in tendon problems. The purposes of the present study were (1) to systematically review the association between lipid disorders and the risk of rotator cuff disease and (2) to provide physicians with guidance to prevent rotator cuff disease.

Background: Atraumatic rotator cuff tear is a common orthopaedic complaint for people >60 years of age. Lack of evidence or consensus on appropriate treatment for this type of injury creates the potential for substantial discretion in treatment decisions. To our knowledge, no study has assessed the implications of this discretion on treatment patterns across the United States. Read More

Finding the way back into the glenohumeral space after a time-consuming rotator cuff reconstruction is not always easy because of swelling of the surrounding soft tissues. We present a safe and quick technical tip on how to reintroduce the arthroscope by means of a transarticular suture. After primary work in the glenohumeral space is performed and before the arthroscope is withdrawn from the joint, a monofilament suture is channeled from the anterior working portal through the glenohumeral joint to exit from the posterior portal.

Superior capsular reconstruction has emerged as a promising technique in the treatment of massive irreparable rotator cuff tears. The technical aspects of the surgery continue to evolve, and scientific studies to evaluate these techniques are emerging. One such area of interest concerns the appropriate thickness of the graft and its role as a spacer. Read More

Purpose: The purposes of this study were to investigate the effect of hand-grip strength (HGS) on the Disabilities of the Arm, Shoulder, and Hand (DASH) score in women with upper extremity musculoskeletal disorders (UEMDs) living in rural communities and examine whether upper extremity diseases affected upper extremity functional activity in each group (normal/low HGS) and whether grip strength (GS) was an effect modifier in upper extremity functional activity.

Methods: A total of 239 women older than 60 years who had completed a medical workup for epicondylitis, rotator cuff tears, and/or hand osteoarthritis were included in the final study. Functional activity was assessed by DASH, and muscle strength was measured by GS. Read More

Background: Painful dysfunctional shoulders with irreparable rotator cuff tears (IRCTs) in active patients are a challenge. Arthroscopic superior capsular reconstruction (ASCR) is a new treatment option originally described using a fascia lata autograft harvested through an open approach.

Hypothesis: We hypothesized that a new method considering the humeral head would distinguish rotator cuff tears (RCTs) and osteoarthritis (OA) better than the critical shoulder angle (CSA).

Methods: A total of 1011 patients were tested in this study and divided into 4 groups: those with RCTs (n = 493), those with OA (n = 73), those with anterior instability (n = 361), and those with adhesive capsulitis (n = 84). The CSA and new radiologic parameters including the humeral head were measured in the true anterior-to-posterior view: the Y angle connecting the lower end of the glenoid (LG), the center of the humeral head (CH), and the upper end of the glenoid (UG); the G angle connecting UG, CH, and the lateral tip of the acromion; the YG angle connecting LG, CH, and the lateral tip of the acromion; and the R angle connecting UG, LG, and CH.

Background: Treatments for rotator cuff (RC) tendinopathy include RC muscle strengthening to promote better muscle recruitment in order to minimize subacromial narrowing during active movement. Glenohumeral adductors recruitment has also been shown to prevent such narrowing in asymptomatic individuals; therefore, adding glenohumeral adductor coactivation during RC strengthening could enhance the efficacy of RC strengthening.

Although the exact function of the subacromial bursa as it relates to rotator cuff repair is still debatable, most surgeons would agree that the more invasive the procedure, the more likely there will be scarring and/or adhesions, which can lead to decreased motion. So, when performing subacromial bursectomy during rotator cuff repair, "Observe due measure, moderation is best in all things [subacromial]." Read More

Aims: In patients with a rotator cuff tear, tear pattern and tendon involvement are known risk factors for the development of pseudoparalysis of the shoulder. It remains unclear, however, why similar tears often have very different functional consequences. The present study hypothesizes that individual shoulder anatomy, specifically the moment arms (MAs) of the rotator cuff (RC) and the deltoid muscle, as well as their relative recruitment during shoulder abduction, plays a central role in pseudoparalysis.

Neuromuscular activity, organized in coordinated patterns, forms the basis of task-specific function in sports and exercise. The content and extent of these patterns may be variable, but include elements of activation/inhibition, co-activation, concentric/eccentric activation, proximal-to-distal activation, plyometric activation, and preactivation stiffness. They may be based on inherent neuromuscular architecture, but are commonly affected by positive or negative adaptations to imposed functional demands. Read More

Background:: The Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 was recently developed to assess physical and mental health and provide an estimated EuroQol-5 Dimension (EQ-5D) score. This instrument needs to be validated for specific patient cohorts such as those with rotator cuff pathology.

Hypothesis:: There is moderate to high correlation between the PROMIS Global-10 and legacy patient-reported outcome measures; PROMIS Global-10 will not show ceiling effects; and estimated EQ-5D scores will show good correlation and low variance with actual EQ-5D scores. Read More

A 14-year-old female ballet dancer sustained an injury during a routine ballet movement that was diagnosed as an ischial tuberosity avulsion fracture. This diagnosis was complicated by extensive soft tissue injury to the hamstrings, adductors, and external rotator musculature. Although uncommon, the potential for this injury should be uniformly considered in adolescent dancers due to the unique stresses in ballet training and the added risk of growth spurts during this stage of development.
