BACKGROUND: Recently, supraspinatus muscle exercise has been reported to treat rotator cuff disease and to recover shoulder function. However, there have been no report on the direct measurement of strain on the supraspinatus tendon during simulated isometric gleno-humeral joint elevation. METHODS: Ten fresh-frozen shoulder specimens with the rotator cuff complex left intact were used as experimental models. Isometric gleno-humeral joint elevation in a sitting position was reproduced with low angle of step-by-step elevation in the scapular plane and strain was measured on the surface layer of the supraspinatus tendon...

BACKGROUND: Massive rotator cuff tears (MRCTs) represent a major clinical concern, especially when degeneration and chronicity are involved, which highly compromise healing capacity. PURPOSE: To study the effect of the secretome of mesenchymal stem cells (MSCs) on tendon cells (TCs) followed by the combination of these activated TCs with an electrospun keratin-based scaffold to develop a tissue engineering strategy to improve tendon-bone interface (TBi) healing in a chronic MRCT rat model...

BACKGROUND: Although recent evidence suggests that any prior shoulder surgery may cause inferior shoulder arthroplasty outcomes, there is no consensus on whether previous rotator cuff repair (RCR) is associated with inferior outcomes after reverse total shoulder arthroplasty (RTSA). PURPOSE: To retrospectively compare outcomes in patients who underwent RTSA with and without previous RCR. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients with prior RCR and those without previous shoulder surgery (control) who underwent RTSA for cuff tear arthropathy or irreparable cuff tear were retrospectively identified from a prospective database...

OBJECTIVE: The aim of this study was to compare the microarchitecture of the greater tuberosity with or without rotator cuff tear and to obtain optimum location for anchor screw insertion for rotator cuff repair. METHODS: Twenty-five humeral heads were harvested from 13 male cadavers of mean age 58.4 years, including 6 humeri with rotator cuff tear and 19 intact humeri. Six regions of interest (proximal, intermediate, and distal zones of the superficial and deep regions) were divided into the anterior (G1), middle (G2), and posterior (G3) areas of the greater tuberosity...

Cryoneurolysis entails using low temperatures to reversibly ablate nerves, with a subsequent analgesia duration measured in weeks or months. Previously, clinical applications for acute pain were limited because treatment originally required exposing the target nerve surgically. However, three developments have now made it possible to provide prolonged postoperative analgesia by cryoneurolysis: 1) new portable, hand-held cryoneurolysis devices, 2) ultrasound machine proliferation, and, 3) anesthesiologists trained in ultrasound-guided peripheral nerve block administration...

BACKGROUND: The optimal technique for arthroscopic rotator cuff repair is controversial, and both single and double-row techniques are commonly used. In the current era of increasing costs, health-care delivery models are focusing on the value of care. In this study, we compared the cost-effectiveness of single-row and double-row reconstructions in patients undergoing arthroscopic rotator cuff repair. METHODS: A cost-utility analysis was performed from the perspective of a publicly funded health-care system...

Superior capsular reconstruction (SCR) of the shoulder has recently gained popularity as an option for joint-preserving shoulder surgery for patients with an irreparable rotator cuff tear. In the absence of glenohumeral arthritis, rotator cuff tear irreparability should only be diagnosed for most patients after a careful diagnostic arthroscopy. Superior capsular reconstruction adds biological, passive, superior constraint to the glenohumeral joint, thereby optimizing the rotator cuff force couples and improving joint kinematics...

INTRODUCTION: "Fosbury flop" tear is an avulsion of the posterosuperior rotator cuff from the bone with reversal healing on its medial bursal-side. This case report describes a unique variant of Fosbury flop tear with a lesion of the musculotendinous junction that healed, for its tendon part, on the anterior humerus and coracoid process. CASE PRESENTATION: A 62-year-old man developed a posttraumatic painful shoulder with active loss of range of motion. Magnetic resonance arthrography demonstrated a lesion of the musculotendinous junction of the supraspinatus with healing of the tendon on the above-mentioned structures (reverse Fosbury flop)...

Pseudoparalysis has been previously described as the inability to elevate the arm over 90° in the setting of a rotator cuff tear. Controversy exists regarding the optimal treatment for patients with a pseudoparalytic shoulder with a rotator cuff tear with options including rotator cuff repair and reverse shoulder arthroplasty. Recent literature suggests that pseudoparalysis can reliably be corrected with a rotator cuff repair and is more cost effective than reverse shoulder arthroplasty. We believe that the arbitrary cutoff of 90° is too generous and leads to confusion...

BACKGROUND: Waterpolo consists of a combination of swimming and throwing with close contact between players. The shoulder is the most frequently injured joint, with a combination of rotator cuff tear and tendinopathy, long head biceps tendinopathy, superior labral lesions and shoulder impingement. This unique combination is a challenge for the clinician who must determine which of these shoulder pathologies is responsible for the onset of pain and the best strategy to rehabilitate the joint and prevent recurrence...

PURPOSE: Symptomatic full-thickness rotator cuff (RC) tears are often recommended for surgical repairs. However, some patients decide not to have surgery. The aim of this study was to see if there was any difference in preoperative variables between the two groups. METHODS: 137 consecutive patients recommended for surgery due to symptomatic full-thickness RC tear were evaluated. At mean 58.1 months after surgery-recommendation, the patients were asked whether they had surgery and their clinical outcome was assessed...

REVIEW
U L Fahlenkamp, C Gerhardt, K-G A Hermann
Even primary diagnostic evaluation of the shoulder is a challenge for radiologists. Many imaging findings that definitely indicate abnormal findings in the untreated shoulder should be evaluated carefully in postoperative patients. Artifacts caused by implants or metal abrasion pose considerable problems in postoperative magnetic resonance imaging (MRI). Classic approaches to minimizing artifacts caused by foreign bodies include using turbo spin echo sequences, increasing bandwidth, and reducing voxel size...

Tendon pathologies are a group of musculoskeletal conditions frequently seen in clinical practice. They can be broadly classified into traumatic, degenerative and overuse-related tendinopathies. Rotator cuff tears, Achilles tendinopathy and tennis elbow are common examples of these conditions. Conventional treatments have shown inconsistent outcomes and might fail to provide satisfactory clinical improvement. With the growing trend towards the use of mesenchymal stem cells (MSCs) in other branches of medicine, there is an increasing interest in treating tendon pathologies using the bone marrow MSC...
