Case: Dorsal dislocations of the distal interphalangeal joint with associated volar base fractures of the distal phalanx are complex injuries that pose challenges for achieving stable reduction and restoring optimal joint function. This case report describes the successful management of a 40-year-old male cardiologist who sustained such an injury after a cricket ball trauma. The treatment involved a combined approach of closed reduction, dorsal extension block pinning, and intrafocal pinning of the volar base fracture.

Case: Thirty-five-year-old man presented with 14 cm segmental tibial defect after crush injury (Gustilo Anderson type-IIIA). Tetrafocal bone transport using Ilizarov frame was performed with 3 osteotomies. Two minor complications-skin invagination and failure at proximal docking site-were addressed.

Evaluating the dynamic co-evolution and feedback mechanisms within socio-ecological systems is crucial for determining the resilience and sustainability of environmental governance strategies. The grass-livestock system, as a complex entity encompassing livestock nutrition, foraging behavior, vegetation ecology, pastoralists' economic income, and policy interventions, indicates that any change in a single element may trigger a chain reaction within the system. This paper uses a system dynamics approach to construct a simulation model of the grass-livestock system in alpine pastoral areas, simulating the long-term dynamic co-evolution of the socio-ecological system in the Qilian Mountains region of China.
