PURPOSE: Lower trapezius (LT) transfer using Achilles tendon allograft or semitendinosus autograft is effective in restoring external rotation in massive irreparable posterosuperior rotator cuff tears (RCT). The purpose of this study was to evaluate if the infraspinatus fascia (IF) could be used in LT transfer to extend the LT tendon. METHODS: Eight fresh-frozen whole-body cadavers were dissected using both shoulders, beach chair position. A 2.5-3 cm wide bundle of the IF was dissected, from the inferior angle of the scapula up to the insertion of the LT which was then detached subperiosteally in continuity with the fascia...

A short cut review was carried out to establish whether intra-articular injection of local anaesthetic is an effective alternative to intravenous analgesia with or without sedation to facilitate reduction of acute shoulder dislocations. Eleven studies were considered relevant to the question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these studies are tabulated. The clinical bottom line is that intra-articular injection of local anaesthetic is a safe and effective method of providing procedural analgesia for the reduction of acute shoulder dislocations...

Mixed-dimensional magnetic heterostructures are intriguing, newly available platforms to explore quantum physics and its applications. Using state-of-the-art many-body perturbation theory, we predict the energy level alignment for a self-assembled monolayer of cobalt phthalocyanine (CoPc) molecules on magnetic VSe2 monolayers. The predicted projected density of states on CoPc agrees with experimental scanning tunneling spectra. Consistent with experiment, we predict a shoulder in the unoccupied region of the spectra that is absent from mean-field calculations...

Dogs have a reputation for empathy toward their owners, which is also supported by some research (e.g., Carballo et al., 2020; Sanford, Burt, & Meyers-Manor, 2018). Many dog owners anecdotally report that dogs comfort them by making visual and/or physical contact when they cry or help them when they are sick. These behaviours provide a good way to assess the capacity for empathy and its physiological correlates in dogs. This study is a replication and extension of Custance and Mayer (2012). We examined whether using laughing as an alternative stimulus to humming produced similar responses to crying...

Proximilization of frozen elephant trunk (FET) necessitates the ligation and reimplantation of the left subclavian artery (LSA), the origin of which is distal and posterior, make rerouting difficult and cumbersome. We describe a rather simple technique for subclavian artery exposure and effective anatomical reconstruction in the mediastinum coupled with hybrid FET utilization for aortic aneurysm in elective and nonelective settings. The division of the sternocleidomastoid coupled with the sandbag behind the left shoulder brings the LSA superficial enabling anastomosis without any difficulty...

BACKGROUND: Revision shoulder arthroplasty may involve the need to remove a well-fixed humeral stem. To avoid this, convertible platform systems have been introduced. The biomechanics of reverse total shoulder arthroplasty (rTSA) differs from anatomic shoulder arthroplasty (aTSA). The different humeral osteotomy and soft tissue tension may jeopardize the optimal results of the converted rTSA. The aim was to evaluate the radiographic parameters of soft tissue distraction when converting an aTSA to rTSA in a platform system and assess the capability of conversion without "over-stuffing" the shoulder in the "best-case scenario"...

This study assessed the additional contribution of balneotherapy on physical therapy in subacute supraspinatus tendinopathy. Ninety patients with subacute supraspinatus tendinopathy were included. They were randomized into two equal groups. In group 1 (n = 45), transcutaneous electrical nerve stimulation (TENS), hot pack, ultrasound treatments, and Codman's and range of motion (ROM) exercises were performed. In group 2 (n = 45), balneotherapy was added to the treatment program. In both groups, shoulder active ROM and handgrip strength were measured...

Opioids are prescribed routinely for pain after total shoulder arthroplasty (TSA). This study was designed to characterize opioid use after elective primary TSA and identify predictors of long-term postoperative opioid use. The authors used the MarketScan administrative claims database to identify 5676 adults who underwent elective primary TSA between 2010 and 2015 and had 1 year or more of continuous insurance enrollment, including prescription drug coverage, postoperatively. Long-term postoperative opioid use was defined as filling prescriptions totaling a 120-day or greater supply during the 3- to 12-month postoperative period...

Ideberg type III glenoid fractures are relatively rare, and the mechanisms of injury and treatment strategies remain controversial. We reviewed the fracture patterns and final radiological findings in four cases. All fractures were wider on the medial side than on the side of the articular surface. All patients had multiple ipsilateral rib fractures; three out of four patients had a concomitant acromion fracture. Therefore, the mechanism of injury for the fracture is assumed to be external force applied in the caudal direction to the medial side of the body of the scapula...

Background: Successful repair of a torn rotator cuff may prevent progression to rotator cuff arthropathy. However, previous studies have shown a substantial rate of failure after rotator cuff repair and characteristics of surgically repaired rotator cuffs that go on to shoulder arthroplasty have not been fully elucidated. The purpose of this study was to determine the patient characteristics and rate at which patients who underwent rotator cuff repair progressed to shoulder arthroplasty...

Background: Superior capsular reconstruction (SCR) for massive, irreparable rotator cuff tears has become more widely used recently; however, ideal tensioning of the graft and the influence on joint kinematics remain unknown. Purpose/Hypothesis: The purpose of this study was to assess the effects of graft tensioning on glenohumeral joint kinematics after SCR using a dermal allograft. The hypothesis was that a graft fixed under tension would result in increased glenohumeral abduction motion and decreased cumulative deltoid forces compared with a nontensioned graft...

Reverse shoulder arthroplasty is a common procedure. While dislocation is a common complication, there are few reports documenting dislocation with associated polyethylene liner dissociation from the humeral tray. There have been 4 instances of this occurrence over 9 years at our institution, and there are specific radiographic clues for diagnosis. Recognizing polyethylene liner dissociation on imaging is important prior to treatment. In a "routine" dislocation, closed reduction may be attempted but when the polyethylene is dissociated, open reduction is the only treatment option, as closed reduction can damage the components...
