A blurred fracture line means that an adequate crustal connection has formed between the fractures, the fracture site is more stable against rotational and lateral shear forces, and displacement does not normally occur. Of course, in some cases, re-fracture and fracture displacement can occur, such as during strenuous sports, which can produce a large load on the fracture site, and in this case, if the bone scab is not strong enough, fracture of the bone scab and re-fracture can occur. In addition, if you fall again during the activity and the injured part is in the same fracture site, it may cause another fracture and fracture displacement.
