TY - JOUR AB - The distal radius is an extremely rare site for epithelioid hemangioendothelioma. Joint preservation to maintain a good wrist joint function is rarely reported. The present study described a case of joint preservation surgery in the distal radius with an uncemented 3D‑printed endoprosthesis and evaluated the endoprosthesis design and short‑term outcomes. A 14‑year‑old boy was diagnosed with epithelioid hemangioendothelioma in radius. Due to the extensive defect and the excessively short length of the residual distal radius after resection, a custom‑made 3D‑printed custom‑made endoprosthesis was designed and fabricated to reconstruct the defect, with the preservation of the wrist joint. The patient had a favorable wrist function and no endoprosthesis‑related complications were observed. The present study presented a case of en bloc tumor resection with joint preservation of the wrist and reconstruction using a 3D‑printed endoprosthesis. Satisfactory postoperative function and low complication rates were found. AD - Department of Orthopedics, West China Hospital, Sichuan University, Chengdu, Sichuan 610041, P.R.
