Interlocking nailing, which has become the method of choice for treating fractures of the femoral and tibial shafts, still lacks ability to provide the important contact-compression at the fracture. An intramedullary compression nail is described, which provides axial compression at the fracture site with tightening of the specially designed distal interlocking screw. This uses the same principle as dynamic compression plating.
The study included 11 femoral and tibial nailings performed for various clinical applications such as acute fractures, non-unions and malunions.
All the fractures attained radiological union, with good skeletal continuity across the fracture, within an average time of 13 weeks in fresh fractures and 18 weeks in non-unions.
Active compression through intramedullary compression nailing has great utility for treating non-unions where it provides greater degree of impaction of its irregular ends. This may prove greatly advantageous to the fracture union through increased stability and the osteogenic potential, particularly when utilized in combination with the small diameter unreamed nails.
交锁髓内钉已成为治疗股骨干和胫骨干骨折的首选方法，但仍缺乏在骨折处提供重要接触加压的能力。本文描述了一种髓内加压钉，其通过拧紧特殊设计的远端交锁螺钉在骨折部位提供轴向加压。这与动力加压钢板使用相同的原理。
该研究包括11例用于各种临床情况（如急性骨折、骨不连和畸形愈合）的股骨和胫骨钉固定术。
所有骨折均实现了影像学愈合，骨折处骨骼连续性良好，新鲜骨折平均愈合时间为13周，骨不连为18周。
通过髓内加压钉进行主动加压在治疗骨不连方面具有很大的效用，它能使不规则的骨折端获得更大程度的嵌插。这可能通过增加稳定性和成骨潜力对骨折愈合极为有利，特别是当与小直径非扩髓钉联合使用时。
