The Pins and Rubber Traction System (PRTS) can be used to treat proximal interphalangeal intra-articular fractures. Our experience is that outcomes are not always excellent and that many patients have reduced joint function or residual deformities. The aim of this study was to evaluate the reasons behind the poorer outcomes of some of the patients treated with this system. A retrospective clinical and radiological evaluation was performed on 15 patients after a minimum of 2 years' follow-up. The mean interphalangeal joint flexion range was 66 degrees (range 0-100) in our series. The review of the literature shows an average active interphalangeal joint flexion of 78 degrees (range 64-95). Reasons for this difference include preoperative delay, technical deficiencies, the learning curve, a lack in postoperative physiotherapy and degenerative changes due to the longer follow-up. Although the Pins and Rubber Traction System seems a simple procedure, a learning curve is necessary to avoid pitfalls.
针式橡胶牵引系统（PRTS）可用于治疗近端指间关节内骨折。我们的经验是，治疗效果并非总是极佳，许多患者存在关节功能减退或残留畸形。本研究的目的是评估使用该系统治疗的部分患者预后较差的原因。对15例患者进行了至少2年随访后的回顾性临床和影像学评估。在我们的系列研究中，指间关节平均屈曲范围为66度（范围0 - 100度）。文献回顾显示，指间关节平均主动屈曲度为78度（范围64 - 95度）。造成这种差异的原因包括术前延误、技术缺陷、学习曲线、术后缺乏物理治疗以及随访时间较长导致的退行性改变。尽管针式橡胶牵引系统看似是一种简单的手术，但为避免失误仍需要经历学习曲线。
