Custom Design & Fabrication of 3D printed cast for ankle immobilisation
Abstract
Management of bone and joint injuries is commonly done by immobilisation using plaster/fibreglass casts. This study describes design and fabrication of patient specific cast using 3D printing. The 3D printed cast while being patient friendly is superior to earlier casts in healing efficacy and hence redefines the joint immobilisation practice. We present here a case of “walk on brace” design and fabrication using 3D printing. The custom design of ankle immobilisation cast was done for an 18-year-old boy having tibia bone fracture during gymnastic activity. The workflow comprises of anatomical data acquisition, CAD, 3D printing, post processing and clinical approval for use. Additional features such as straps, anti-slip inner surface and tread for floor grip were incorporated in the design.
