Use of 3D Printing Technology for Cervical Thoracic Lumbosacral Orthosis Fabrication

Abstract

Introduction: This case report describes orthotic design using computed tomography and three-dimensional printing technology combined with traditional orthotic modalities in a newborn patient with chondrodysplasia punctata and cervical spinal stenosis. At day 5 of life, the infant was referred for fitting with a prefabricated cervical collar. Because of the infant's unique stature and small size, traditional prefabricated devices could not be used. The spinal instability and critical nature of the infant prevented traditional methods of orthosis fabrication. A multidisciplinary team used imaging, 3D printing technology, and traditional orthosis fabrication methods to construct a cervical thoracic lumbosacral orthosis (CTLSO). Materials and Methods: Using computed tomography scans, data-segmenting software, and a 3D printer, a life-sized model of the patient's upper body was constructed. Traditional plaster molding and high-temperature orthoplastic techniques were used to fabricate a custom cervical thoracic lumbosacral orthosis for spinal stabilization, necessary for safe patient transport and handling. Results: The custom orthosis demonstrated proper fit and stability, as evidenced by postfitting scans. With orthosis in place, needed care could be provided to the patient more safely and efficiently. In addition, the infant could be held by the caregivers, increasing parental/infant bonding. Conclusions: Technological advances, including the ability to use computer tomography scans in combination with three-dimensional printers, can be a safe and effective option in situations of difficult orthosis fabrication for medically fragile patients.
