摘要全肘关节置换术(TEA)最常见的适应证是类风湿性关节炎、骨性关节炎和创伤性关节炎。随着假体的改进和手术技术的发展，TEA的适应证已经扩大到了创伤后不稳定、内固定失败及老年新鲜肱骨远端骨折。经典的Bryan-Morrey入路最常见并发症为尺神经症状及术后肱三头肌肌力减弱。而保留肱三头肌的入路，经肱三头肌两侧进入，增加了手术操作难度，虽避免了术后肱三头肌无力的并发症，但仍存在术后尺神经症状、皮下剥离范围大、引流量多等问题。2018年9月O'Driscoll教授介绍了一种他改良的小舌形瓣入路，命名为Diamond-Pop入路，但目前尚未见文献对其进行报道。笔者采用回顾性病例系列研究分析2018年9月— 2019年9月北京积水潭医院收治的20例肘部创伤和关节炎患者临床资料，探讨Diamond-Pop入路行TEA临床预后。

abstractsThe most common indications for total elbow arthroplasty (TEA) are rheumatoid arthritis, osteoarthritis, and post-traumatic arthritis. However, with the rapid development of the prosthesis and surgical techniques, the indications of TEA have been expanded to post-traumatic instability, failure of internal fixation, and acute comminuted distal humeral fractures in elderly patients. The most common complications of the classic Bryan-Morrey approach are postoperative ulnar nerve symptoms and weakness of the triceps muscle. Although the triceps-sparing approach enters the elbow joint through both sides of the triceps and retains the triceps brachii, it adds the operation difficulty and there still exist problems regarding postoperative ulnar nerve symptoms, extensive subcutaneous dissection, and large amount of drainage. In September 2018, Professor O'Driscoll introduced his modified small tongue-shaped flap approach, named as Diamond-Pop approach, but it has not been reported yet in recent literatures. The authors conducted a retrospective case series study to evaluate the clinical outcomes of 20 patients with elbow trauma or arthritis treated by TEA using this approach in Beijing Jishuitan Hospital from September 2018 to September 2019.
