Background Patients with large bony defects of the ankle who wish to avoid amputation have limited surgical intervention options for limb salvage. Each of these interventions are technically complex and present significant risk for complications. The use of a patient-specific 3D-printed titanium cage in conjunction with a tibiotalocalcaneal (TTC) arthrodesis using a retrograde nail is another management option. This case adds to the scarce published literature on this technique. Case presentation This report presents the case of a 16-year-old female who suffered a traumatic partial amputation of her left distal lower extremity following an all-terrain-vehicle accident that resulted in a 10.0 × 10.0 cm skin laceration and a 5-cm subsegmental bony loss of the distal tibia. She was successfully treated using a patient-specific 3D-printed titanium truss cage in conjunction with a TTC arthrodesis using a retrograde nail. Conclusions The decision to amputate or attempt limb salvage in a severely injured lower limb is still a topic of active debate. However, literature has shown that patients who undergo limb salvage surgery have better psychological health outcomes and equivalent functional outcomes as patients who have undergone amputation. Therefore, research on techniques that optimize and advance limb salvage surgery is needed. As the numerous potential benefits and limitations of patient-specific 3D-printed implants are assessed throughout the field of orthopedics, further research and cost-analysis will be required. Cases such as the one presented add to the limited existing literature of patient-specific 3D-printed implant for treatment of large distal lower extremity bony defects.
