ABSTRACT

Background: Open reduction and plate fixation is the standard operative treatment for displaced midshaft clavicle fracture. However, sometimes it is difficult to achieve anatomic reduction by open reduction technique in cases with comminution.

Methods: 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. A computed tomography (CT) scan is taken of both clavicles in patients with a unilateral displaced comminuted midshaft clavicle fracture. Both clavicles are 3D printed into a real-size clavicle model. 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.

Results: 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. 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 plate can be inserted through a small incision and fixed with locking screws without exposing the fracture site. Seven comminuted clavicle fractures treated with this technique achieved good bone union.

Conclusions: 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. Level of evidence V.

Mentions: Under the patient's agreement to use the data and the agreement with the 3D printing company to safely protect the data and destroy it upon completion of the model, the data (in DICOM format) is sent to a 3D printing company to produce a real-size clavicle model. The 3D printing company converts the DICOM data into a STL file format using specialized software called MIMICS (Materialise Interactive Medical Image Control System Software, Materialise, Belgium). A real-size fractured clavicle model is 3D-printed utilizing an inkjet printing technique via a 3D printing machine (Projet x60 series, 3D System Inc., Rock Hill, SC, USA). Using the mirror imaging technique, the uninjured side clavicle is 3D-printed to produce a suitable replica of the damaged side clavicle pre-injury (Fig. 2). To minimize the overall cost of model production, attention was focused on gross size and shape rather than fine detail. The two solid clavicle models are sent to the hospital via mail courier once completed. The model production process takes approximately 2 to 3 days from initial CT scan to obtaining the solid model. The total cost of each clavicle replica is under US$100.Fig. 2
