骨折

1. Origins, structure, and basic meaning

• Structure: 骨折 is read こっせつ and is a noun for a broken bone or the resulting injury.
• Basic usage: Use 骨折を想定する for a simulated fracture scenario and 腕を骨折する to state which body part was fractured.

2. Common pitfalls and similar expressions

• を with a body part
  • In 腕を骨折する, を marks the body part that is fractured. It does not make the entire person the object.
• 骨折 and けが
  • けが broadly covers wounds and injuries, while 骨折 specifically identifies a broken bone. Not every injury is a fracture.
• Simulation and actual event
  • 骨折を想定した人形 is a dummy representing a fracture for training. It is not a report that a real person suffered one.
