A fracture is primarily a disruption of the continuity and integrity of the bone. An inset fracture is a subtype of fracture in which both ends of the fracture are inserted into each other, and inset fractures tend to cause shortening of the limb. Of course, insertion fractures are not always typical in terms of local deformity and pain, such as insertion fractures of the femoral neck, which sometimes allow appropriate walking. However, the local symptoms may gradually worsen. In the case of an impingement fracture, it is mainly determined accurately by local X-rays and, if necessary, CT and 3D reconstruction. If the fracture is locally stable and has no significant impact on function, it can be treated conservatively with cast fixation and braking. However, if the insertion fracture causes significant shortening of the limb, which has a serious impact on the function, or if there is a certain local angulation, which affects the functional recovery, it is necessary to perform incision and internal fixation or other treatment after the swelling subsides.
