After the fracture should be treated by surgery as early as possible to shorten the time of bed rest. Long-term bed rest can mainly lead to the following hazards: 1. Crushing pneumonia: the incidence is high, and sputum is not easily coughed out after bed rest and accumulates in the lungs, which can lead to lung infection, and the condition is heavy and not easily cured; 2. Decubitus ulcer: long-term pressure on the sacrum and hip after bed rest can lead to skin breakdown, infection and fever; 3. Thrombosis: bed rest leads to slowed blood flow, which is easy to complicate stroke, venous thrombosis of the lower limbs, and swelling of the lower limbs.
