Clinically, we often encounter patients or family members who ask the doctor with a repositioned or post-operative x-ray, “Why is there still a little bit of this bone here that is not right?” Doctors often need to spend a lot of energy to explain, and some patients still have doubts until the fracture heals and function is restored. To what extent is a fracture reset considered satisfactory? This involves two professional terms: anatomic and functional repositioning. Anatomic repositioning: The correction of various displacements of the fracture ends and the restoration of normal anatomic relationships, with complete alignment (the contact surface of the two fracture ends) and alignment (the relationship between the two fracture segments on the longitudinal axis) are called anatomic repositioning. Functional repositioning: In some cases, despite the best efforts, the fracture is not anatomically repositioned, and the fracture has no significant impact on the function of the limb after healing is called functional repositioning. The general standard for fracture repositioning is to achieve functional repositioning, i.e.: (1) Rotational displacement of the fracture part and separation displacement must be completely corrected. Mild angular displacement in line with the direction of joint activity can be corrected later by shaping. Angular displacement perpendicular to the direction of joint activity cannot be shaped by itself and must be completely corrected at the time of repositioning. (2) After the lateral displacement of the diaphyseal fracture is corrected, the lateral displacement should be about 1/3, and after the lateral displacement of the metaphyseal fracture is corrected, the lateral displacement should be about 3/4. (3) When the fracture of the upper limb is shortened and displaced more in adults, it has little effect on the function of the limb, while the shortened displacement of the lower limb fracture is not allowed to exceed 2 cm. Above, the fracture alignment and alignment are good, which is anatomical repositioning. Above, the alignment is good; if the alignment is more than 1/2 one, it is a functional repositioning. After healing, it will not affect the function. It is also a satisfactory reset. The above paragraph has too much jargon, which may be difficult for people to understand. Simply put, the fracture reset mainly depends on whether the whole bone is basically kept straight or not, don’t pay too much attention to the deviation of the position of part of the broken bone and the partial misalignment between the bone ends, as long as it meets the criteria of functional reset, it will have little effect on the future; functional reset is also considered a satisfactory reset. In order to look good on the film, it is harmful to repeatedly reposition the bone by manipulation or excessive stripping during surgery. Of course, the functional reduction is a satisfactory reduction only for general (most) fractures. Fractures involving the intra-articular region require anatomical repositioning.
