Ulnar collateral ligament (UCL) reconstruction has been successfully utilized to treat symptomatic UCL insufficiency in overhead athletes. Despite the overall success of the procedure, attempts have been made to improve upon the original technique with the goal of hastening return to sport. Most recently, there has been interest in repairing or reconstructing the native ligament with internal brace (IB) augmentation. Biomechanical cadaveric studies assessing UCL repair with IB augmentation have attempted to evaluate the efficacy of this treatment; however, the literature is seemingly divided on its benefit. Preliminary clinical studies suggest internal bracing may allow a faster return to sport than conventional techniques. The purpose of this review was to provide an analysis of the current evidence on IB augmentation in UCL repair of the elbow as it pertains to biomechanical advantages/disadvantages, reported surgical techniques, and clinical outcomes in comparison with traditional UCL reconstruction techniques.
尺侧副韧带（UCL）重建已成功用于治疗上肢运动员有症状的UCL功能不全。尽管该手术总体上取得了成功，但人们一直在尝试改进原始技术，以期加快恢复运动的速度。最近，人们对使用内支架（IB）增强修复或重建天然韧带产生了兴趣。评估使用IB增强进行UCL修复的生物力学尸体研究试图评估这种治疗方法的疗效；然而，关于其益处的文献似乎存在分歧。初步临床研究表明，与传统技术相比，内支架固定可能使运动员更快恢复运动。本综述的目的是分析当前关于IB增强在肘部UCL修复中的证据，涉及其生物力学优缺点、报道的手术技术以及与传统UCL重建技术相比的临床结果。
