This document discusses early and delayed complications that can arise from fractures. Early complications include visceral injuries to organs like the brain, chest, abdomen, and pelvis. Vascular injuries such as cuts, compression, thrombosis, or spasm of major arterial vessels can also occur. Compartment syndrome, which is an increase in pressure within a closed muscle compartment, is another potential early complication. Delayed complications include delayed union, malunion, non-union, avascular necrosis, joint instability, growth disturbances, and osteoarthritis.
