Proximal humerus fractures (PHF) are common, yet their optimal management remains debated. Reverse total shoulder arthroplasty (rTSA) is an increasingly popular option, particularly for non-reconstructible or osteoporotic fractures. Despite this trend, current literature provides limited guidance with regards to surgical timing and patient selection for rTSA. A trial of non-operative management might be beneficial for many patients who are not clearly indicated for surgery, provided this does not have a major negative impact on results for those who ultimately require rTSA. The purpose of this study was to investigate whether delayed reverse shoulder arthroplasty for fracture (>28 days from injury) is associated with any difference in complication rates or functional outcomes relative to acute surgery. ⋯ Delay in performing primary rTSA for management of PHF does not lead to an increase in complication rates but it may come at the cost of worse functional outcomes in patients who ultimately require rTSA.

Biodegradable magnesium-based alloy implants represent a promising option in orthopedic surgery, as the clinical outcomes have been reported to be comparable to those of titanium implants and no surgical interventions are required for removal. To date, little is known about the results of the use of these implants in children and adolescents. Therefore, the aim of the present study was to analyze the safety and performance of these implants in children and adolescents. ⋯ Magnesium-based implants in children and adolescents results in good clinical outcomes when used for fracture stabilization, osteotomy and osteochondral defect refixation. Future studies are needed to further analyze the significance of the transient appearance and temporal development of radiolucent zones in the growing skeleton as well as the long-term performance of these implants.

The purpose of this study was to construct a rat caudal vertebral body fracture model and to analyze the association and histological characteristics of vertebral body fracture with endplate injury and adjacent intervertebral disc degeneration. ⋯ In rat caudal vertebral body fractures, a fracture with endplate injury is more likely to induce or accelerate degeneration of adjacent intervertebral discs.
