As surgical techniques evolve, new intraoperative complications are prone to occur. With percutaneous spinal fixation, the control of implants and instruments can be a challenge when compared with open surgery, particularly if unintended instruments are retained or difficult to retrieve. In this report, the authors describe a case in which Jamshidi needle fragments broke within the vertebral body. Extraction of the fragments was accomplished using a small pedicle screw tap to first engage the retained metal and then to loosen the surrounding bone to allow retrieval and preservation of the anatomical structures needed to complete the intended operation. This technique may prove useful for the retrieval of deformable, cannulated metal pieces in minimally invasive surgery.
随着外科技术的发展，新的术中并发症更容易发生。与开放性手术相比，经皮脊柱固定时，植入物和器械的控制可能具有挑战性，尤其是当意外的器械被保留或难以取出时。在本报告中，作者描述了一例 Jamshidi 针碎片在椎体内断裂的情况。使用小的椎弓根螺钉丝锥首先固定保留的金属，然后松开周围的骨头，以允许取出并保留完成预期手术所需的解剖结构，从而完成了碎片的取出。该技术可能对微创性手术中可变形的、有套管的金属碎片的取出有用。
