Volumetric classification: unveiling the true extent of rotator cuff tears.

Introduction: Rotator cuff injury diagnosis involves comprehensive clinical, physical, and imaging assessments, with magnetic resonance imaging (MRI) being pivotal for detecting and classifying these injuries. However, the absence of a universally accepted classification system necessitates a more precise approach, advocating for the use of three-dimensional (3D) modeling to better understand and categorize rotator cuff tears.

Methodology: This research was conducted as a prospective, single-institution study on 62 patients exhibiting full-thickness rotator cuff tears.

Diagnosis typically relies on high clinical suspicion and complementary imaging studies, with >90% of cases documented in males between the fourth and sixth decades of life. Reports of DBT ruptures in females are scarce, mostly involving partial and degenerative injuries.

Materials And Methods: The patients were randomized into 2 groups: in the HA group a single dose of intra-articular hylan G-F 20 was administered and in the T control group a dose of triamcinolone 20 mg was administered. The participants were evaluated at 1 week, 1, 3, and 6 months after the procedure.

A Simple Technique to Restore Tension of a Loose Suture Bridge During Rotator Cuff Repair: Save the Repair.

The transosseous equivalent suture bridge technique has been widely used for rotator cuff repair, especially for large tears. During the fixation of the second lateral anchor, the first group of sutures may become loose due to anchor malposition or manual overtensioning of the second group of sutures. To restore the suture's tension, a spare suture from the second lateral anchor may be passed beneath the loose suture to tighten it with a simple knot.

Vertical Jump Tests: A Safe Instrument to Improve the Accuracy of the Functional Capacity Assessment in Robust Older Women.

Age-related decreases in muscle function lead to disabilities and are associated with negative health outcomes in older people. Although several physical tests can be used to assess physical performance, muscle strength, and power, their interpretation can be hampered by the ceiling effect of some of them. The aim of this study was to assess whether vertical jump tests are safe in terms of physical integrity and whether they are useful in assessing physical performance in forty-one robust older women.

Rotator Cuff Tear Susceptibility Is Associated With Variants in Genes Involved in Tendon Extracellular Matrix Homeostasis.

Rotator cuff tears (RCT) is a multifactorial disease with genetic factors contributing for the disease etiology. We hypothesized that genetic variants in genes involved in extracellular matrix (ECM) homeostasis may alter susceptibility to RCT. We evaluated 20 polymorphisms of genes involved in ECM homeostasis in 211 cases of full-thickness tears of the supraspinatus (N  = 130; N  = 81) and 567 age-matched controls (N  = 317; N  = 250).
