Anatomical considerations, diagnosis, and treatment of medial and posterolateral elbow rotatory instability in athletes: an arthroscopic perspective and literature review.

Purpose: Elbow joint instability results from the disruption of one or more stabilizing anatomical structures. The two most common forms of instability are posterolateral rotatory instability (PLRI) and medial elbow instability (MEI), particularly in athletes. This review aims to explore the anatomical foundations, diagnostic methods, and therapeutic approaches for PLRI and MEI in athletes.

Lateralization and Distalization Shoulder Angles in Reverse Shoulder Arthroplasty: Are They Still Reliable and Accurate in All Patients and for All Prosthetic Designs?

Recently, the lateralization shoulder angle (LSA) and distalization shoulder angle (DSA) have been proposed to assess lateralization and distalization in reverse shoulder arthroplasty (RSA). However, there is insufficient evidence about the influence of patient anatomy and prosthesis design on these measurements. This study aims to investigate the impact of patient anatomy and implant design on LSA and DSA measurements and to assess the validity of the previously reported "optimal" ranges for these parameters.

Limb Salvage and Reconstruction of a Complex Upper Extremity Injury: A Case Report.

Introduction: Complex upper extremity trauma poses us with significant challenges in orthopedic and reconstructive surgery due to the complex anatomy and functional importance of the extremities. These injuries are often the result of high-energy mechanisms like motor vehicle collisions, which makes their management particularly demanding. Making the decision between limb salvage and amputation in such cases requires careful consideration of multiple factors such as functionality, risk of complications, and recovery.

A Case Report of Acute Achilles Tendon Rupture in a Patient With Multimorbidity Treated With Endoscopic Flexor Hallucis Longus Transfer.

Acute Achilles tendon rupture (AATR) in patients with multimorbidity poses a significant therapeutic challenge to surgeons because of the increased risk for wound-healing-related complications. Thus, nonoperative management has been these individuals' most widely adopted treatment. We report a case of a 66-year-old patient with AATR who was treated with endoscopic flexor hallucis longus (FHL) transfer.

Afternoon kick-off, evening kick-off, or night kick-off in the first German Bundesliga - A possible Injury risk factor?

Introduction: This retrospective cohort study aimed to evaluate the impact of kick-off time on the risk of injury for professional soccer players in the first German Bundesliga. It was hypothesized that late kick-off times would have a negative effect on muscle and ligament injuries to the ankle and knee.

Methods: Kick-off times and injury data were collected over 5 consecutive seasons (1530 matches; 2014-2019) from two media-based registries (transfermarkt.

Surgical Challenges and Outcomes in Treating a Floating Upper Arm With Multiple Humerus Fractures and Radial Neck Fractures.

Complex humerus fractures associated with high-energy trauma present significant surgical challenges due to their impact on limb functionality and structural integrity. This case report details the treatment of a floating upper arm injury, characterized by multiple humerus fractures and a radial neck fracture, in a 50-year-old male following a vehicular accident. The patient exhibited fractures at the proximal, mid-shaft, and distal segments of the humerus, necessitating an integrated surgical approach to effectively manage these injuries.

Fractures of the proximal femur and hip osteoarthrosis - coincidence or coherence?

Purpose: The current study aimed to investigate the correlation between the grade of radiographic hip osteoarthritis (OA) and the fracture pattern observed in fragility fractures of the proximal femur. The information may help in cases of occult hip fractures.

Methods: In this retrospective study all 448 patients treated with fragility fractures of the proximal femur in the years 2014-2018 were included.
