The fracture can basically heal more than 2 months after the sacral fracture injury, and there will be no pain at that time. The pain will be more pronounced in the first 1 week after the injury and will be more significantly reduced almost 2 weeks or more after the injury, because there is a local primitive bone scab connection at this time. Almost 1 month after the injury there is basically only slight pain because there is a large amount of bone scab growth at this time. Most of the simple sacral fractures can be treated conservatively by bed rest, while a few serious fractures or obvious dislocation of the sacroiliac joint need to be considered for surgical treatment. The pain can be treated with painkillers, such as Loftinzine extended-release tablets or Aminotrimadol painkillers, and also with local creams such as fluoride and Bilofen Babu cream.
