Abstract

Introduction

3D printing in distal humerus fracture surgery has not been evaluated despite increasing popularity.

Methods

A retrospective study comparing distal humerus fracture surgery pre-operative plans to actual surgical plans and constructs was conducted using radiographs, CTs, 3D CT reconstructions, and 3D printed models.

Results

No difference existed among imaging modalities for approach or plate size. 3D CT reconstructions best predicted lateral plate size. 3D printed models best predicted medial plate size. 3D printed models elicited higher confidence in pre-operative plan.

Discussion

3D printed models were an equivalent tool for pre-operative planning compared to other modalities in our study.

3D打印模型在肱骨远端骨折切开复位内固定术前手术规划中的应用效果

3d打印在肱骨远端骨折手术中的应用越来越广泛，但尚未得到评估。方法采用x线片、CT、3D CT重建及3D打印模型对肱骨远端骨折手术术前方案与实际手术方案及施工方案进行回顾性比较研究。结果不同的成像方式在入路和板大小上没有差异。三维CT重建最能预测侧板大小。3D打印模型最能预测中板尺寸。3D打印模型提高了术前计划的可信度。在我们的研究中，与其他模式相比，3d打印模型是一种等效的术前计划工具。
