ABSTRACTBackground: The acromioclavicular dislocation is the resultant injury of the patient's fall with the arm in adduction. It constitutes the 9% of all shoulder Injuries. The most common classification was described by Rockwood, which consists of 6 degrees, according to the displacement of articulation, each one with a prognosis and therapeutic value. Several surgical techniques have been described for this condition: open, percutaneous and arthroscopic.
Objective: Provide a description of the technique used in the Central Military Hospital for reduction of acromioclavicular dislocation.
Material: Image intensifier and radiation protection equipment, perforator, 4.0 mm cannulated drill, 2 mm guide drill, Arthrex Tightrope system.
Surgical technique: In supine and with anatomical marking, with a 1cm incision in the cephalic face of the clavicle, tricortical drilling is performed with guide drill 2.0, perforated cuatricortical with 4.0mm cannulated drill. Tightrope system is introduced under fluoroscopic control and the coracoid button is horizontalized, the dislocation is reduced and the wound is closed.
Conclusions: The minimally invasive technique by fluoroscopy is a fast, useful and reproducible method for the reduction of acute dislocations of the acromioclavicular joint.
