The need for MRI after a fracture generally depends on the specific site of the fracture. CT and X-rays of long tubular fractures of the extremities are sufficient to provide sufficient information without MRI, but for patients with intra-articular fractures or spinal fractures, MRI is required. The main purpose of MRI for intra-articular fractures is to understand whether there is damage to the intra-articular ligaments and other important tissues. The purpose of MRI for the knee, for example, is to clearly diagnose whether there is damage to the cruciate ligaments, collateral ligaments or meniscus at the time of fracture, and whether there is damage to the intra-articular cartilage, so that the fracture can be correctly determined and the correct surgical approach can be developed. For patients with spinal fractures, an MRI can help to understand whether there is compression and occupancy of the spinal canal and whether there is nerve damage, which can help to make a correct decision about the timing of surgery and the surgical approach, such as whether a decompression of the vertebral plate is needed. Therefore, MRI is not necessary for all fractures, but only for fractures affecting the joints and spine to assist in the diagnosis.
