Introduction: Shoulder-to-head contact is the most common cause of concussions in ice hockey, accounting for 42% of cases in the National Hockey League. The goal of this project was to determine how shoulder pad stiffness, modified by adding foam padding over the shoulder cap of existing shoulder pads, affected head impact severity when participants delivered checks to an instrumented dummy.
Methods: Fifteen participants administered "the hardest shoulder checks they were comfortable delivering" to the head of a dummy equipped with triaxial accelerometers and gyros mounted in its helmet. Trials were conducted with participants wearing two common types of shoulder pads, with and without a 2-cm-thick layer of polyurethane foam over the shoulder pad cap.
Results: When participants delivered checks with foam-modified pads versus unmodified pads, there was a decrease of 25.0% in the average peak linear head acceleration (28.73g vs 38.31g, mean difference = 9.58g, 95% confidence interval = 6.35-12.81, P < 0.0001) and a decrease of 12.4% in the average value of peak rotational head velocity (838.0°·s vs 956.7°·s, mean difference = 118.65°·s, 95% confidence interval = 55.37-181.94, P = 0.001). The protective benefit of the foam layer did not depend on the type of shoulder pad or the checking scenario.
Conclusion: The integration of foam padding on top of the plastic caps of shoulder pads reduced impact severity to the head and warrants further examination as a method for contributing to the prevention of brain injuries in ice hockey.

Article Synopsis
- Primary atopic disorders (PAD) are rare genetic conditions caused by specific gene variants that affect skin and immune function, making diagnosis challenging among common allergic disease cases.
- Identifying PAD requires recognizing clinical red flags like family history and unusual infections, as conventional lab tests are inadequate for definitive diagnosis.
- Whole-genome sequencing (WGS) enhances diagnostic efficiency and accuracy, but requires careful interpretation and collaboration among specialists to effectively manage PAD cases.
Single-Stage Arthroscopic Minced Cartilage Implantation for Focal Cartilage Defects of the Glenoid Including Glenolabral Articular Disruption Lesions: A Technical Note.

Article Synopsis
- Anterior shoulder dislocations are often linked to cartilage defects called GLAD lesions, which are crucial for shoulder stability but frequently overlooked.
- These glenoid cartilage defects can lead to ongoing pain and may result in osteoarthritis, highlighting the need for surgical intervention.
- While traditional methods like prosthetic arthroplasty work for older patients, newer techniques, such as the cost-effective AutoCart procedure, show promise for younger patients by using a simpler one-step process for treating isolated cartilage defects.
Article Synopsis
- The study investigates the effects of injecting satellite myoblasts (SM) and mesenchymal stem cells (MSCs) into rats with chronic rotator cuff (RC) tears to improve muscle recovery and reduce fat degeneration.
- After standardized surgery and treatment, the rats were monitored for 14 weeks to assess the recovery of muscle mass and reduction of adipose tissue in those treated with SM and MSC compared to a control group.
- Results showed that the combination of surgical repair with SM and MSC injections significantly enhanced muscle mass and tendon healing while reducing fat tissue, offering a potential new approach for treating chronic RC injuries.
