摘　　要：BACKGROUND Giant cell tumors(GCT)are most commonly seen in the distal femur.These tumors are uncommon in the small bones of the hand and feet,and a very few cases have been reported.A giant cell tumor of the talus is rarely seen clinically and could be a challenge to physicians.CASE SUMMARY We report a rare case of GCT of the talus in one patient who underwent a new reconstructive surgery technique using a three-dimensional(3D)printing talar prosthesis.The prosthesis shape was designed by tomographic image processing and segmentation using technology to match the intact side by mirror symmetry with 3D post-processing technologies.The patient recovered nearly full range of motion of the ankle after 6 mo.The visual analogue scale and American Orthopaedic Foot and Ankle Society scores were 1 and 89 points,respectively.CONCLUSION We demonstrated that 3D printing of a talar prosthesis is a beneficial option for GCT of the talus.
