Internal fixation is usually removed at about 1 year after acromioclavicular joint dislocation, provided that the acromioclavicular joint has recovered well. Internal fixation materials for acromioclavicular joint dislocations include clavicle hook plates and Kirschner wire tension bands. This type of internal fixation is usually removed at about 1 year after surgery, taking into account the recovery of the acromioclavicular joint dislocation. For those who have recovered well in the early stage, the fixation can be removed as early as possible to avoid affecting the function of the joint in the later stage. If the acromioclavicular joint does not recover well and the acromioclavicular ligament does not recover satisfactorily, the time of removal should be extended appropriately. If the internal fixation is dislocated, affects the joint movement or is infected, it should be removed at an early stage according to the condition of the patient.
