Titanium internal fixation of acetabular fractures can be used for long periods of time when the body does not have an adverse reaction to it. Titanium alloys are biocompatible, and most patients who retain them have no significant adverse effects, so most internal fixation is not necessary to remove. Moreover, the risk of internal fixation removal after acetabular fracture is high, and it is not recommended unless there is a situation that necessitates its removal. If there is compression of the nerve, internal fixation displacement, etc., then generally need to be removed. Otherwise, titanium internal fixation of acetabular fractures is generally not recommended for removal. Regular orthopedic review of acetabular fracture surgery is recommended, and it is recommended to decide whether to remove the titanium internal fixation after the doctor’s comprehensive judgment.
