Designed in conjunction with Ken Koval, MD, Bruce Ziran, MD, and Brian Cole, MD, the Acumed Clavicle Hook Plating System includes four plate lengths and three hook depths. The Acumed Clavicle Hook Plating System provides a third solution to acromioclavicular (AC/CC) joint dislocations and lateral clavicle fractures, in addition to both the Acumed Distal Clavicle Plates and Acu-Sinch Repair System. To assist the surgeon in implant selection, the unique Clavicle Hook Depth Sizer allows for measurement for all three hook depths with a single instrument, and the Clavicle Hook Plate Length Sizer measures for both left and right plate lengths on either side of the instrument. The Clavicle Hook Plating System must be used in conjunction with the Acumed Clavicle Plating System, which contains the instruments and screws necessary to implant the Clavicle Hook Plates. Indications for Use: The Acumed Clavicle Hook Plating System is intended for fixation of lateral clavicle fractures, osteotomies, malunions, nonunions and dislocations of the acromioclavicular joint.
