Posttraumatic, limb length discrepancy in adults is a challenge to treat, and multiple treatment protocols over the years have shown varying levels of success and complications. Before the introduction of the PRECICE nail in 2011, our preferred method of limb lengthening used an Ilizarov or Taylor Spatial frame. To assess the PRECICE nail, we evaluated the accuracy and complications during treatment in a series of skeletally mature patients with posttraumatic femoral limb length discrepancy. The surgical technique along with a case series of 8 patients are described in detail. On average, the target lengthening for the PRECICE nail was 44 mm, and all patients achieved lengthening within 2 mm and complete bony consolidation. The only observed complication in our series was a broken screw 1 year after the patient started weight-bearing. The PRECICE nail demonstrated promising results and was useful for bone regeneration and consolidation without the need for additional procedures. The rate of complications was low compared with previous methods, making this device an excellent treatment option.
成人创伤后肢体长度差异是一个治疗难题，多年来多种治疗方案都显示出不同程度的成功率和并发症。在 2011 年 PRECICE 钉引入之前，我们首选的肢体延长方法是使用 Ilizarov 或 Taylor 空间框架。为了评估 PRECICE 钉，我们评估了一系列骨骼成熟的创伤后股骨肢体长度差异患者在治疗过程中的准确性和并发症。手术技术以及 8 例患者的病例系列详细描述。平均而言，PRECICE 钉的目标延长长度为 44mm，所有患者均在 2mm 内实现了延长，并完全骨融合。在我们的系列中，唯一观察到的并发症是患者开始负重 1 年后的一个螺丝断裂。PRECICE 钉显示出良好的效果，可用于骨再生和巩固，无需额外的手术。与以前的方法相比，并发症的发生率较低，这使得该设备成为一种极好的治疗选择。
