Abstract

Intra-articular fractures of the distal humerus are complex injuries that often require surgery with the goal of restoring elbow range-of-motion and function. Open reduction and internal fixation has been the preferred surgical modality; however, restoration of the medial and/or lateral columns can be complicated in fractures involving a major loss of the articular surface and bony structure. Over the past decade, 3-dimensional (3D) printing has made significant advances in the field of orthopedic surgery, specifically in guiding surgeon preoperative planning. Recently, the incorporation of 3D-printing has proven to provide a safe and reliable construct for the restoration of anatomy in complex trauma cases. We present a 47-year-old woman who sustained a complex, intra-articular distal humerus fracture with associated shearing of the capitellum that went onto malunion. Patient was treated with a patient-specific 3D-printed custom elbow prosthesis with excellent outcomes. Our goal was to shed light on the use of 3D-printing technology as a viable salvage option in treating complex, intra-articular distal humeral fractures associated with lateral condylar damage that subsequently went onto malunion.

三维打印定制肘关节假体用于复杂肱骨远端关节内骨折骨不连的挽救性治疗。
肱骨远端关节内骨折是一种复杂的损伤,通常需要通过手术来恢复肘关节的活动范围和功能。开放复位和内固定一直是首选的手术方式;然而,在涉及关节面和骨质结构严重缺失的骨折中,内侧和/或外侧支柱的修复可能会很复杂。在过去十年中,三维打印技术在骨科手术领域取得了重大进展,特别是在指导外科医生进行术前规划方面。最近,3D 打印技术已被证明可为复杂创伤病例提供安全可靠的解剖结构修复。我们介绍了一名 47 岁的女性患者,她的肱骨远端发生了复杂的关节内骨折,并伴有髌骨剪切,最终导致骨不连。患者接受了患者专用的 3D 打印定制肘关节假体治疗,取得了很好的疗效。我们的目标是阐明使用3D打印技术作为一种可行的抢救方案,治疗伴有外侧髁损伤的复杂关节内肱骨远端骨折,这种骨折随后会发生骨不连。
