Limb lengthening by distraction osteogenesis is an accepted orthopaedic surgical technique. The Precice intramedullary lengthening system is the most recent innovation in limb lengthening. Early results have been favourable in femoral lengthening but there is little reported on the outcome in tibial lengthening. The aim of this study is to present our early results of Precice tibial lengthening, and the stepwise evolution of our surgical technique.
A case series of 17 consecutive tibial lengthenings were prospectively analysed. Healing index, length achieved, range of motion, and complications were recorded. The initial cases followed the recommended surgical technique. Progressive regenerate deformity during lengthening required changes to the surgical method.
No cases were lost to follow-up. All the nails lengthened at the desired rate. There were no complications of infection or poor regenerate formation. Progressive valgus and procurvatum was prevented in later cases by the positioning of Poller blocking screws at the time of nail insertion.
The tibial Precice nail is successful in obtaining length and good regenerate formation. The recommended technique was insufficient to control the deforming forces from the lower limb muscle compartments during lengthening. We therefore recommend the addition of multiple blocking screws in an amended technique.

通过牵张成骨进行肢体延长是一种公认的骨科手术技术。Precice髓内延长系统是肢体延长领域的最新创新。早期结果显示其在股骨延长方面效果良好,但关于胫骨延长的结果报道较少。本研究的目的是展示我们使用Precice系统进行胫骨延长的早期结果,以及我们手术技术的逐步演变。
对连续17例胫骨延长病例进行前瞻性分析。记录愈合指数、延长长度、活动范围和并发症。最初的病例遵循推荐的手术技术。延长过程中逐渐出现的再生骨畸形促使我们对手术方法进行改变。
无失访病例。所有髓内钉均按预期速度延长。无感染或再生骨形成不良的并发症。在后期病例中,通过在插入髓内钉时放置Poller阻挡螺钉,预防了逐渐出现的外翻和前凸畸形。
Precice胫骨髓内钉在实现延长长度和良好的再生骨形成方面是成功的。推荐的技术不足以控制延长过程中来自下肢肌肉间隔的致畸形力。因此,我们建议在改良技术中增加多个阻挡螺钉。
