Open reduction and plate fixation is the standard operative treatment for displaced midshaft clavicle fracture. This technique can be used for a unilateral displaced comminuted midshaft clavicle fracture when it is difficult to achieve anatomic reduction by open reduction technique. Seven comminuted clavicle fractures treated with this technique achieved good bone union.

The plate can be inserted through a small incision and fixed with locking screws without exposing the fracture site. The 3D-printed uninjured clavicle model can be utilized as a template to select the anatomically precontoured locking plate which best fits the model. The 3D-printed fractured clavicle model allows the surgeon to observe and manipulate accurate anatomical replicas of the fractured bone to assist in fracture reduction prior to surgery. Using the mirror imaging technique, the uninjured side clavicle is 3D printed into the opposite side model to produce a suitable replica of the fractured side clavicle pre-injury. Both clavicles are 3D printed into a real-size clavicle model. A computed tomography (CT) scan is taken of both clavicles in patients with a unilateral displaced comminuted midshaft clavicle fracture. We describe a novel technique using a real-size three dimensionally (3D)-printed clavicle model as a preoperative and intraoperative tool for minimally invasive plating of displaced comminuted midshaft clavicle fractures. However, sometimes it is difficult to achieve anatomic reduction by open reduction technique in cases with comminution.
