| Summary: | Post-traumatic limb deformity is often multiplanar and thus is a difficult pathology to deal with surgically. Precise preoperative planning and accurate intraoperative execution are two main important steps that lead to satisfactory outcome. Computer-assisted planning and three-dimensional-printed patient-specific instrumental guides provide excellent aid to the two steps, respectively. We report a case of post-traumatic lower limb deformity in a patient who underwent closing wedge corrective osteotomy with the aid of the aforementioned new technologies. 中 文 摘 要: 創傷後肢體畸形通常是多平面的，因此是手術治療的困難病理。 準確的術前規劃和準確的術中執行是導致滿意結果的兩個主要重要步驟。電腦輔助術前規劃和三維打印患者特定器械指南分別為兩個步驟提供了極好的幫助。 我們報告了在創傷後下肢畸形，借助上述新技術來進行閉合楔形矯正截骨術的病例。 Keywords: closing wedge, osteotomy, patient-specific instrumentation, three-dimensional printing, virtual planning
