NEDD4 enhances bone‑tendon healing in rotator cuff tears by reducing fatty infiltration.

Rotator cuff tears (RCT) can cause shoulder pain, weakness and stiffness, significantly affecting daily life. Analysis of the GSE103266 dataset revealed significant changes in the mTOR/PI3K/Akt signaling pathway and lipid metabolism‑related pathways, suggesting that fatty infiltration may affect RCT. The analysis indicated that the ubiquitin ligase NEDD4 plays a critical role in RCT.

Evidence-based approach to the shoulder examination for subacromial bursitis and rotator cuff tears: a systematic review and meta-analysis.

Introduction: Shoulder pain represents a common patient complaint evaluated in a primary care setting. Approximately two thirds of these patients have rotator cuff injuries, with rotator cuff tears (RCTs) and subacromial impingement syndrome (SIS) accounting for a majority of causes. An accurate and efficient diagnostic strategy focused on physical examination findings may lead to improved outcomes and less functional disability.

CCL4L2 participates in tendinopathy progression by promoting macrophage inflammatory responses: a single-cell analysis.

Background: Tendinopathy is very common in clinical practice, which is highly prevalent in athletes, sports enthusiasts and other people involved in high-load weight-bearing activities. Common types of tendinopathy include rotator cuff injury, Achilles tendinitis, tennis elbow and so on. Macrophages (Macs) are key immune cells in the pathogenesis of tendinopathy.

[Comparative study on effectiveness of injecting platelet-rich plasma with different concentrations of leukocytes under ultrasound in treatment of supraspinatus tendon injury].

Objective: To compare effectiveness of injecting platelet-rich plasma (PRP) with different concentrations of leukocytes under ultrasound in treatment of supraspinatus tendon injury.

Methods: A clinical data of 30 patients with supraspinatus tendon injury, who met the selection criteria and were admitted between December 2022 and December 2023, was retrospectively analyzed. Thirty patients were treated with 4 injections of leukocyte-poor PRP (LP-PRP, =10), leukocyte-rich PRP (LR-PRP, =11), and triamcinolone ( =9), with an interval of 7-10 days between each injection.

Long Head of Biceps Tendinopathy Is Associated With Age and Cuff Tendinopathy on MRI Obtained for Evaluation of Shoulder Pain.

Background: Shoulder pain-mostly related to rotator cuff tendinopathy-is the most common reason adults seek upper limb specialty care. Tendinopathy of the long head of the biceps may be part of rotator cuff tendinopathy, which most of us develop as we age. Evidence that these processes are related and that both are part of human shoulder senescence could contribute to a reconceptualization of shoulder tendinopathy as a single set of age-related changes, which are often well-accommodated, sometimes misinterpreted as an injury, and associated with notable nonspecific treatment effects, thus meriting caution regarding the potential for overtreatment.

Predicting bursal-side supraspinatus tendon tears with the acromioclavicular angle.

Background: Bursal-side supraspinatus tendon tears are a common form of rotator cuff injury, often associated with acromial impingement and other extrinsic factors. Existing anatomical parameters, such as the lateral acromion angle, acromial index, and critical shoulder angle, have been studied in relation to rotator cuff tears; however, reliable indicators specific to the risk of bursal-side supraspinatus tears remain lacking. The acromioclavicular (AC) angle, which reflects the angular relationship between the acromion and clavicle, may offer a new predictive marker for this specific pathology.

Whether the Indications for Reverse Shoulder Arthroplasty Should Continue to Be Expanded? A Systematic Review and Meta-Analysis.

Background: It is still unclear whether reverse total shoulder arthroplasty (RTSA) has advantages over traditional hemiarthroplasty (HA) and anatomic total shoulder arthroplasty (ATSA) in the treatment of complex shoulder joint diseases. Therefore, this study aims to evaluate the clinical effectiveness of RTSA in the treatment of complex shoulder joint diseases and further determine whether it is necessary to expand the indications of RTSA.

Method: We conducted a systematic search of studies published between January 1, 2012 and May 31, 2023 in PubMed, Embase, and Cochrane databases.

Impact of Reach Height on Estimated Rotator Cuff Compression Risk in Manual Wheelchair Users With Spinal Cord Injury.

Reaching is a common daily activity requiring a range of humeral elevation that contributes to rotator cuff compression. The purpose of this study was to estimate supraspinatus and infraspinatus tendon compression risk relative to the acromion and coracoacromial ligament during reaching by manual wheelchair users with spinal cord injury. A cross-sectional design was used to evaluate 8 participants (7 males, median [range] age 36 y [23-61]).

Effect of Decellularized Amniotic Membrane on the Tendon-Bone Integration in Rotator Cuff Repair: A Comparative Rat Model Study.

Objective: Rotator cuff retear after arthroscopy repair is a difficult complication that is often due to poor tendon-bone healing. Decellularized amniotic membrane (DAM) has a variety of bioactive substances which have great potential to enhance tendon-bone healing. However, DAM has three layers, of which the middle basement layer is dense and thick.

Proximal Humerus Fractures: A Review of Anatomy, Classification, Management Strategies, and Complications.

Proximal humerus fractures are prevalent in older adults, particularly women, primarily due to osteoporosis and increased fall risk. These fractures often result from low-energy falls in elderly patients, while in younger individuals, they are more likely to occur with high-energy trauma, which may involve additional injuries to soft tissue and neurovascular structures. Proper anatomical understanding, including key structures and blood supply, is crucial for effective management and to prevent complications.

Inflammation and Fatty Infiltration Correlates with Rotator Cuff Muscle Atrophy in Hypercholesterolemic Yucatan Microswine.

Rotator cuff injuries are the most common injuries among active and training astronauts. According to the CDC, 1 in 4 adults in the U.S.

Dry needling as an adjunct treatment to multimodal rehabilitation protocol following rotator cuff repair surgery: a preliminary, randomized sham-controlled trial.

Background: Rotator cuff repair (RCR) is one of the most prevalent procedures to manage rotator cuff tears (RCT). Postoperative shoulder pain is a common complication following RCR and may be aggravated by activation of myofascial trigger points (MTrP) associated with the injury to the soft tissues surrounding the surgical incision. This study aimed to describe a preliminary, randomized, sham-controlled trial to evaluate the effectiveness of implementing 4 sessions of myofascial trigger point dry needling (MTrP-DN) as a muscle treatment approach along with 10 sessions of multimodal rehabilitation protocol (MRh) consisting of therapeutic exercise, manual therapy, and electrotherapy on postoperative shoulder pain, range of motion (ROM), strength, and functional outcome scores for patients following RCR surgery.

Association between acromion morphological parameters and rotator cuff tears in Somali population-a three-dimensional computed tomographic study.

Background: Previous research has established connections between the acromion index (AI), critical shoulder angle (CSA), acromiohumeral distance (AHD), and lateral acromion angle (LAA) with the incidence of rotator cuff tears (RCTs). Despite numerous international studies exploring the variability of shoulder joint morphology and parameters, research incorporating these parameters has yet to be conducted in Somalia. This study aims to analyze and describe the radiological parameters of acromion morphology in the Somali populations.
