Three-Dimensional Printed Talar Prosthesis With Biological Function For Giant Cell Tumor Of The Talus: A Case Report And Review Of The Literature
WORLD JOURNAL OF CLINICAL CASES(2021)
摘要
BACKGROUNDGiant 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 SUMMARYWe 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.CONCLUSIONWe demonstrated that 3D printing of a talar prosthesis is a beneficial option for GCT of the talus.
