It is important to avoid sexual intercourse after a fracture because it can cause stress reactions in the fracture end, resulting in abnormal alignment and alignment of the fracture end, which can affect the healing of the fracture and may result in deformed healing of the fracture. Sexual activity is generally avoided after 3 months of fracture, because the fracture is not fully healed and not strong enough to cause re-displacement of the fracture during activity. Especially in the case of lumbar fractures, it is generally necessary to wait at least 6 months, because there is a risk that the local aseptic inflammatory metabolic production will gradually increase during activity, which will stimulate the peripheral nerves and cause pain.
