Pectoralis Major Tendon Tear in a 13-Year-Old Female High-Level Gymnastic Athlete: A Case Report.

Tears of the pectoralis major tendon have become more common due to the rising popularity of weightlifting and contact sports, yet they have not been described in young adolescents. A 13-year-old female high-level gymnastic athlete presented with left shoulder pain after a fall off the uneven bars. After excluding other diagnoses, magnetic resonance imaging (MRI) revealed a pectoralis major tendon tear.

Sparse and inconsistent reporting of pre- and post-operative radiographic angles of total knee arthroplasty using true unrestricted kinematic alignment: An umbrella review and secondary meta-analysis.

Purpose: To identify, synthesise and critically appraise findings of systematic reviews and meta-analyses on pre- and post-operative radiographic angles (lateral distal femoral angle [LDFA], medial proximal tibial angle [MPTA] and hip-knee-ankle [HKA] angle) of unrestricted kinematic alignment versus mechanical alignment in total knee arthroplasty (TKA).

Methods: Two authors searched MEDLINE, EMBASE and Epistemonikos for systematic reviews, with or without meta-analyses, that reported on TKA outcomes using unrestricted kinematic alignment. The methodological quality of the included systematic reviews and meta-analyses was independently assessed using A MeaSurement Tool to Assess systematic Reviews (AMSTAR-2).

SDIMMMER: A Proposed Clinical Approach to Optimize Cellular Physiology in Regenerative Medicine.

SDIMMMER is an acronym intended for use in both clinical practice and medical research. It facilitates a comprehensive evaluation of a patient's metabolic profile and serves as a mnemonic for the following key assessment areas: Sleep, Diet, Microbiome, Metabolism, Medications, Exams, and Rehabilitation. In the clinical setting, SDIMMMER's primary objective is to monitor and manage the patient's metabolic status, particularly targeting low-grade chronic systemic inflammation, a hallmark of metabolic syndrome (MS).

The Distribution of Coronal Plane Alignment of the Knee Classification in a Sample of Spanish Southeast Osteoarthritic Population: A Retrospective Cross-Sectional Observational Study.

The Coronal Plane Alignment of the Knee (CPAK) classification is a pragmatic distribution of nine phenotypes for coronal knee alignment that can be used on healthy and arthritic knees. Our study aimed to describe the CPAK distributions in a Spanish southeast osteoarthritic population and compare them to other populations' published alignment distributions. Full-leg standing X-rays of the lower limb from 528 cases originating from the so-called Vega Alta del Segura (southeast of the Iberian Peninsula) were retrospectively analysed.

Fungal Shoulder Periprosthetic Infections: A Systematic Review.

: Data regarding fungal PJIs of the shoulder are scarce. The present systematic review aims to identify and evaluate all published shoulder fungal PJIs in an effort to better understand the diagnostic and therapeutic approach to these infections. : A systematic review according to the PRISMA guidelines was conducted, locating all shoulder fungal PJIs.

Regenerative Inflammation: The Mechanism Explained from the Perspective of Buffy-Coat Protagonism and Macrophage Polarization.

The buffy-coat, a layer of leukocytes and platelets obtained from peripheral blood centrifugation, plays a crucial role in tissue regeneration and the modulation of inflammatory responses. This article explores the mechanisms of regenerative inflammation, highlighting the critical role of the buffy-coat in influencing macrophage polarization and its therapeutic potential. Macrophage polarization into M1 and M2 subtypes is pivotal in balancing inflammation and tissue repair, with M1 macrophages driving pro-inflammatory responses and M2 macrophages promoting tissue healing and regeneration.

mG-modified mt-tRF3b-LeuTAA regulates mitophagy and metabolic reprogramming via SUMOylation of SIRT3 in chondrocytes.

N7-methylguanosine (mG) modification is one of the most prevalent RNA modifications, and methyltransferase-like protein-1 (METTL1) is a key component of the mG methyltransferase complex. METTL1-catalyzed mG as a new RNA modification pathway that regulates RNA structure, biogenesis, and cell migration. Increasing evidence indicates that mG modification has been implicated in the pathophysiological process of osteoarthritis (OA).

Rebuilding Stability: Exploring the Best Rehabilitation Methods for Chronic Ankle Instability.

Chronic Ankle Instability (CAI) is a common condition characterized by repeated episodes of ankle "giving way" and impaired balance, leading to functional limitations. Various rehabilitation techniques, including balance training, proprioceptive exercises, whole-body vibration (WBV), and novel approaches like stroboscopic vision, are used to address these deficits. This review evaluates the effectiveness of different rehabilitation interventions for CAI management.

Standing on Elevated Platform Changes Postural Reactive Responses during Arm Movement.

: This study investigated the behavior of postural adjustments throughout the entire action: from the preparatory phase (anticipatory postural adjustment, APA), the focal movement phase (online postural adjustments, OPA), to the compensatory phase (compensatory postural adjustment, CPA) while raising the arms in a standing position, both with eyes opened and closed. The goal was to analyze the effects of reduced sensorial information and different heights on postural muscle activity during these three phases. : Eight young women performed rapid shoulder flexion while standing on the ground and on a 1-m elevated platform.

The Use of Social Media in Orthopedic and Trauma Surgery Education: A Cross-Sectional Survey of German-Speaking Residents and Medical Students.

Background/objectives: Social media has become a significant part of daily life, with platforms like Facebook and WhatsApp dominating usage. The COVID-19 pandemic further increased social media activity, including within the orthopedic community due to restrictions on physical gatherings. Despite the benefits of instant access to educational resources and interaction with experts, the lack of regulated editorial oversight on social media raises concerns about misinformation and privacy.

Evolution and Innovations in Bone Marrow Cellular Therapy for Musculoskeletal Disorders: Tracing the Historical Trajectory and Contemporary Advances.

Bone marrow cellular therapy has undergone a remarkable evolution, significantly impacting the treatment of musculoskeletal disorders. This review traces the historical trajectory from early mythological references to contemporary scientific advancements. The groundbreaking work of Friedenstein in 1968, identifying fibroblast colony-forming cells in bone marrow, laid the foundation for future studies.

Lesser Metatarsophalangeal Joint Instability: Open Surgery Treatment Alternatives.

Lesser metatarsophalangeal joint plantar plate degeneration and tear typically presents as an attritional pattern of capsuloligamentous deficiency in middle-aged patients or sports-related chronic injuries. Knowledge of the anatomy, pathophysiological basis, common patterns, grading and classification of these injuries, and indications for surgery will aid imaging interpretation in the preoperative setting. The acuity and extent of injury, tissue quality, and functional requirements of the patient influence clinical decision-making with respect to surgical management.

Lateral femoral impaction fractures during an ACL tear extend posteriorly on the weight-bearing area of the tibiofemoral joint.

Purpose: Posterior elongation of the physiological terminal sulcus (TS) due to lateral femoral condyle impaction fracture (LFC-IF) after an anterior cruciate ligament (ACL) tear could potentially decrease the weight-bearing area of the tibiofemoral joint, decrease the tension on lateral meniscus and cause flattening of the LFC which would influence rotational knee motion and cause anisometry of the lateral and anterolateral stabilizers. Therefore, the purpose of the study was to assess if the LFC-IF elongates the physiological TS posteriorly.

Methods: One hundred patients magnetic resonance images (MRIs) (75 males, 25 females, mean age 32.
