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

骨折治疗已经取得了巨大的进步，部分原因是新的植入物通过微创技术对许多骨折进行了内固定。例如，复杂的股骨骨折现在通过复杂的“锁定”钉来治疗，这种钉只需要插入几个小切口，效果更好。尽管取得了这些进展，但即使使用专门的锁定接骨板，发生在关节附近的关节骨折仍然具有挑战性，部分原因是难以实现关节面的解剖复位（愈合后残留位移≥ 2 mm的关节面骨折导致关节炎的风险较高）。为了更好地利用这些新的固定装置，我们需要更好的微创手术技术，但目前还没有有效的术中手段来可视化3D骨碎片。特别是，复杂的多碎片关节骨折通常使用手术暴露进行复位，
