The definition of fracture alignment alignment generally refers to fractures of long tubular bones. The requirements are that the alignment should be more than 1/2 from the orthogonal x-ray or the lateral x-ray, and the dislocation should not be greater than 0.5 cm, and then the angulation should not be greater than 10 degrees according to the physiological curvature. If the repositioning does not meet the above requirements, then it may cause delayed healing of the fracture and bone discontinuity. Even if the fracture does heal, it may heal deformed. If the above requirements are not met, surgical treatment is required. The requirement for surgical treatment is anatomical repositioning, especially for intra-articular fractures, which must be treated surgically and must achieve anatomical repositioning, otherwise traumatic osteoarthritis will be left behind and the joint will be painful when walking.
