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.

Shoulder injuries in Brazilian professional football players: epidemiological analysis of 3828 games.

Objectives: Football is a globally played sport that poses potential risks for musculoskeletal injuries. Upper-limb injuries have a lower incidence rate than lower-limb injuries but can still cause absenteeism and performance impairment in football players. This descriptive epidemiological study aimed to evaluate and compare the epidemiological data on shoulder injuries among professional football players in two major Brazilian football championships.

Immunohistochemical analysis of the quadriceps femoris muscle before and after total knee arthroplasty.

Background: The number of total knee arthroplasties (TKA) has increased steadily with the aging of the population. This surgical procedure is recognized for its success in pain relief and restoration of knee function. However, decreased quadriceps femoris (QF) muscle strength after TKA is frequently observed but with unknown etiology.

Surgical repair of the medial head of the gastrocnemius: two case reports and review.

The gastrocnemius medial head distal musculotendinous junction injury is relatively common. Musculature contraction in an already stretched structure leads to muscle breakdown. Patients affected are often physically active middle-aged men.

Rotator Cuff Lesion and Obesity: A Demographic and Metabolic Evaluation.

 To analyze the relationship between the presence and severity of rotator cuff (RC) injury with obesity and the time of exposure to obesity. Secondarily, to evaluate the relationship and prevalence of demographic and metabolic factors in obese individuals with RC injury.  This is a cross-sectional study with 235 obese patients (body mass index [BMI] ≥ 30 kg/m ).

HYLAN G-F 20 VERSUS TRIAMCINOLONE IN THE TREATMENT OF PRIMARY SHOULDER OSTEOARTHRITIS. RANDOMIZED TRIAL.

Introduction: The aim of this study was to evaluate the effect of using an intra-articular injection of hylan G-F 20 (HA group) on primary shoulder osteoarthritis compared with an intra-articular triamcinolone injection (T group).

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.

Automatic MRI segmentation of pectoralis major muscle using deep learning.

To develop and validate a deep convolutional neural network (CNN) method capable of selecting the greatest Pectoralis Major Cross-Sectional Area (PMM-CSA) and automatically segmenting PMM on an axial Magnetic Resonance Imaging (MRI). We hypothesized a CNN technique can accurately perform both tasks compared with manual reference standards. Our method is based on two steps: (A) segmentation model, (B) PMM-CSA selection.

Bilateral pectoralis major MRI in weightlifters: findings of the non-injured side versus age-matched asymptomatic athletes.

Objective: To evaluate magnetic resonance imaging (MRI) features of the contralateral side in weightlifting athletes with pectoralis major (PM) tears. We hypothesized that MRI of the non-injured side may present increased pectoralis major tendon (PMT) length and thickness and greater pectoralis major muscle (PMM) volume and cross-sectional area when compared with the control group.

Methods: We retrospectively identified MRI cases with unilateral PM injury and reviewed imaging findings of the contralateral side.

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.

Arthroscopic Superior Capsule Reconstruction Using Three-Dimensional Preoperative Planning: Technique Description.

We describe a technique using a fascia lata autograft with 3-dimensional (3D) printing to reconstruct the rotator cuff. Prototyping constitutes the construction of physical prototypes with high complexity after virtual studies. Such models increase the knowledge of the characteristics and size of rotator cuff injuries, thus improving the accuracy of determining the correct size of the graft to be used in superior capsule reconstruction.
