  1. [해외논문]   Proximal Junctional Failure in Adult Spinal Deformity Surgery: Incidence, Risk Factors, and Management  

    Spina, Nicholas T. (Address reprint requests to Brandon Lawrence, MD, Department of Orthopaedic Surgery, University of Utah, 590 Wakara Way, Salt Lake City, UT 84108) , Abiola, Rasheed , Lawrence, Brandon D.

    초록

    Proximal junctional failure (PJF) remains a challenging aspect and complication of adult spinal deformity surgery. The incidence of PJF ranges from 1%-40% with the cause being multifactorial and attributed to fracture of the upper instrumented vertebrae, spondylolisthesis, implant failure, or progression of proximal junctional angle. Risk factors include patients over 55, osteoporosis, anterior or posterior fusion, fusion to sacrum, sagittal plane deformity, and magnitude of lumbar lordosis correction (>30°). Patient presentation varies from purely asymptomatic radiographic increase of proximal junctional angle to intractable pain with progressive myelopathy in the setting of cord compression at the upper instrumented vertebrae. The initial management of PJF includes bracing and optimization of bone healing biology through the use of anabolic agents. If symptoms persist or progress surgical stabilization and decompression may be required. Continued research into the risk factors, a better understanding of the goals of correction, and a increased realization of the biomechanics of alternative techniques at the proximal aspect of these deformity patients may help with prevention and management at all stages of adult spine deformity care.

  2. [해외논문]   Stereotactic Navigation in Complex Spinal Surgery: Tips and Tricks

    초록

    Stereotactic navigation has become an indispensible tool for accurately inserting spinal instrumentation and localizing hidden anatomy. The first-generation navigation systems used slow, and relatively inaccurate methods to synchronize (register) the surgical anatomy with computed tomography images obtained preoperatively. Newer systems overcome these limitations by using 3-dimensional images obtained intraoperatively to register the workstation. They also employ robust software to display the anatomy in orthogonal planes with superimposed images of surgical instruments. These innovations have dramatically improved the effectiveness of stereotactic navigation and allowed image guidance to be a routine and nearly seamless adjunct to spine surgery. The purpose of this article is to provide a brief overview of stereotactic navigation in spine surgery, describe our methods for registration and direct referencing and share lessons learned for best practice use of this promising technology.

    초록

    Cortical bone trajectory, also called cortical screw trajectory, is a novel, less invasive fusion alternative for disorders affecting the lumbar spine. Cortical screw constructs have several touted advantages over traditional pedicle screw constructs. First, the surgical exposure required for instrumentation placement is less than that required for traditional pedicle screw placement. This reduced exposure can help reduce blood loss and other approach-related morbidity. Second, the unique screw trajectory, along with a cortically threaded screw, allows for increased cortical bone purchase within the lamina and pedicle. This improved bone purchase can result in improved screw pullout strength, and possibly reduce the chance of screw loosening. Finally, cortically placed screw heads rest on top of the vertebral lamina, which is significantly more medial than traditional pedicle screws, making them more accessible and rod placement more straightforward. Cortical bone trajectory has been validated with several biomechanical cadaveric studies and shows promise with early clinical testing. The cortical screw trajectory may provide patients with lumbar spine pathology a less invasive fusion alternative. This article serves to describe the operative technique and provides a current review of the literature.

  4. [해외논문]   The Current Role of Robotic Technology in Spine Surgery

    초록

    Robotic technology is widely used in manufacturing, industry and some surgical applications, such as urological or joint replacement surgery. Its role in spine surgery is currently in (1) optimizing accuracy of instrumentation placement, most notably pedicle screws, and, (2) diminishing radiation exposure during surgical procedures. Pedicle screw placement can be achieved through a variety of techniques (freehand, fluoroscopy assisted, computer assisted, and robotically guided). Comparing the accuracy rates of these various techniques can be challenging as there is heterogeneity among the skill of surgeons using these methods. However, the literature suggests that the accuracy of robotic guidance of screw placement is at least comparable to other known techniques and some reports have suggested higher accuracy rates when using robotic technology. Though robotic technology in spine surgery is currently still in its nascency, there is great potential for other surgical applications including active automated instrumentation.

  5. [해외논문]   Cervical Arthroplasty  

    St. Onge, Michael (Address reprint requests to John France, MD, Department of Orthopaedics, Robert C. Byrd Health Sciences Center, West Virginia University, P.O. Box 9196, Morgantown, WV 26506–9196.) , France, John
    Operative techniques in orthopaedics v.27 no.4 ,pp. 283 - 289 , 2017 , 1048-6666 ,

    초록

    Cervical disc arthroplasty is a spinal motion-preserving technique performed to treat symptomatic cervical disc disease. The anticipated benefits of preserving motion at the operated level include maintenance of cervical alignment and motion, decreasing stress on adjacent segments, and potentially decreasing the development of symptomatic adjacent level disc degeneration. Favorable short- and mid-term results have demonstrated superiority over standard anterior cervical discectomy and fusion in clinical outcomes and need for reoperation. Nonetheless, surgeons need to exercise caution when selecting appropriate patients for cervical disc arthroplasty and adhere to strict surgical indications and meticulous surgical technique.
