“…We reviewed all causes for total talar replacement and summarized eight articles with a total of 74 taluses replaced ( Table 1 ). 10 – 17 Those studies regarding distal tibia replacement were excluded, except revision with total talar replacement after ankle arthroplasty. The most common reason for performing total talar replacement was osteonecrosis of the talus, followed by trauma.…”

“…For limitations, we failed to compare the cost regarding 3D printed prosthesis with other conventional total talus replacement prosthesis, since none of the literatures mentioned the cost. 10 – 17 However, to facilitate future comparison, we listed our cost here. The 3D printed talus prosthesis, made by ChunLi Co., cost about 31,000 RMB (4,750 USD).…”

PurposeArthrodesis is one of the most widely accepted surgical recommended methods for tumors of the talus, but it may be associated with poor limb functions. The aim of this study was to present a novel reconstruction with ankle function preserved after en bloc talus tumor resection.Patient and methodA 43-year-old female with mesenchymal sarcoma of the talus was admitted in West China Hospital. Total talar replacement with three-dimensional (3D) printed modular prosthesis was prepared for reconstruction. The 3D printed modular prosthesis was designed exactly as the mirror image of the contralateral talus with complete filling of the sinus tarsi and subtalar joint space. The upper modular component of prosthesis was made of ultra high molecular weight polyethylene, and the lower component, titanium alloy. Pre-drilled holes in three directions were prepared for screw fixation of the subtalar joint.ResultsThe patient underwent en bloc talus resection through anterior approach, followed by reconstruction with the 3D printed prosthesis. The whole procedure took 2 hours, and intra-operative blood loss was 50 mL. At the last follow-up, our patient was disease free and she could walk almost normally without any aid or pain. The Musculoskeletal Tumor Society score was 26/30. The American Orthopedic Foot and Ankle Society score was 91/100. The range of motion for dorsiflexion and plantar flexion was 40°. And no abnormalities were observed in the roentgenograph.ConclusionTotal talar replacement with a 3D printed modular prosthesis may be an effective procedure for patients with tumors of the talus as it could maintain ankle function.

“…Limb-salvage surgery with marginal excision was performed. The operation began with a straight skin incision similar to the approach for total ankle replacement over the anterior ankle 8 . The anterior capsule of the tibiotalar joint was incised, and the talus was exposed.…”

“…3D printing allows the development of custom‐made devices, which are currently exempt from third party oversight, quality management strategies and compliance with device essential principles. However, the applications of these devices in surgery are broad, ranging from education, training and surgical planning to implanting customized prostheses (Fig. ).…”

“…). The benefits of these applications have been widely documented in the literature and media, although reproducible data regarding long‐term risks of the technology and comprehensive health economic studies are lacking . As the technology matures, the ability to manufacture 3D printed models of patient's body parts and surgical instruments is no longer restricted to research laboratories and manufacturers who have established pathways of managing experimental technology and stringent ethical guidelines.…”
