Abstract :
Three dimensional printing has greatly advanced over the past decade and has made an impact in
several industries. Within the field of orthopaedic surgery, this technology has vastly improved education and
advanced patient care by providing innovating tools to complex clinical problems. Anatomic models are frequently
used for physician education and preoperative planning, and custom instrumentation can assist in complex surgical
cases. Foot and ankle reconstruction is often complicated by multiplanar deformity and bone loss. 3D printing
technology offers solutions to these complex cases with customized implants that conform to anatomy and patient
specific instrumentation that enables precise deformity correction.
Case presentation: The authors present four cases of complex lower extremity reconstruction involving segmental
bone loss and deformity –failed total ankle arthroplasty, talus avascular necrosis, ballistic trauma, and nonunion of
a tibial osteotomy. Traditional operative management is challenging in these cases and there are high complication
rates. Each case presents a unique clinical scenario for which 3D printing technology allows for innovative solutions.
Conclusions: 3D printing is becoming more widespread within orthopaedic surgery. This technology provides
surgeons with tools to better tackle some of the more challenging clinical cases especially within the field of foot
and ankle surgery.
