Application of Mirror Image 3D-Printing Technology Bone Cement in Treatment of Stage IIIb Necrosis of the Lunate Bone.

Background: At present, conventional operations are weak for pain relief and restoring the carpal joint function in the treatment of avascular necrosis of the lunate bone.

Case report: Mirror image 3-dimensional (3D)-printing technology has rarely been reported for the treatment of lunate bone necrosis, The use of mirror 3D-printed lunar bone replacement and bone cement technology in the treatment of stage IIIb lunar bone necrosis has been rarely reported in previous literature. Personalized customized 3D-printed prostheses have become an effective solution for solving many complex cases, and the flexible application of bone cement technology can also achieve satisfactory clinical results. The authors report 3 patients who underwent mirror printing of lunar bone prostheses based on healthy side lunar bone computed tomography data, 3D printing of lunar bone prostheses replacement through small incisions, and intraoperative selection of alternative bone cement technology based on actual conditions.

Conclusion: Mirror image 3D printing relieved the pain and resulted in satisfactory functional recovery for stage IIIb lunate bone necrosis.
