Advanced real-time 3D imaging, planning and navigation of fracture surgery

在骨折治疗方面取得了巨大的进步，部分原因是新的植入物用微创技术在内部固定了许多骨折。例如，复杂的股骨骨折现在可以通过复杂的“锁定”钉来治疗，这种钉只需要几个小切口就可以插入，从而获得更好的结果。尽管取得了这些进展，发生在关节附近的关节骨折仍然具有挑战性，即使使用专门的锁定钢板也是如此，部分原因是很难实现关节表面的解剖复位(关节表面骨折愈合时残留移位2 mm或更多，导致关节炎的风险很高)。为了更好地利用这些新的固定设备，我们需要更好的微创手术技术，但目前还没有有效的术中三维可视化骨碎片的手段。特别是，复杂的多段关节骨折常规通过手术暴露复位，手术暴露可能增加。

Tremendous advances have occurred in fracture management, due in part to new implants that internally fixate many fractures with minimally invasive techniques. For example, complex femoral fractures are now treated by sophisticated 'locking' nails that require only a few small incisions to insert, giving better outcomes. Despite these advances, articular fractures - which occur near joints - are still challenging even when using specialized locking plates, in part because of the difficulty in achieving anatomic reduction of the joint surface (articular surface fractures that heal with 2 mm or more of residual displacement are at high risk of causing arthritis). To better exploit these new fixation devices we need better minimally invasive surgical techniques, but there currently is no efficient intraoperative means of visualizing bone fragments in 3D. In particular, complex multi-fragment articular fractures are routinely reduced using surgical exposures that may increase
