  • Anchor for JumpFig. 1

    Illustration showing the sites and extent of the unilateral unsegmented bar in 171 patients.

    Figure Description
  • Anchor for JumpFig. 1

    Linear rim penetration was increased for retrieved Charité total disc replacement components exhibiting severe impingement. Provided are boxed ranges of the 25th to 75th percentile and whiskers showing the 1st and 4th quartiles. The length of the whiskers is equal to 1.5 times the box height; anything outside of this range is considered an outlier and is shown as an open circle. Representative images are also provided to illustrate both impingement classifications. A significant difference between impingement groups was determined with use of independent t tests.

    The CONSORT (Consolidated Standards of Reporting Trials) diagram. ICBG = iliac crest bone graft.

  • Anchor for JumpFig. 1

    Detailed diagram of patient selection. BS = bone scanning, CT = computed tomography, MRI = magnetic resonance imaging, and pts = patients.

    Figure Description
  • Anchor for JumpFig. 1

    Distribution of patients with atypical numbers of vertebrae.

    Figure Description
  • Anchor for JumpFig. 1

    Application of motor evoked potential (MEP) electrodes and recording of amplitudes. A pair of stainless-steel needle electrodes separated by approximately 3 cm was inserted in each target muscle, and the MEP signals were visualized on a transcranial electrical stimulation (TES)-MEP monitor.

    Fig. 1-A A thirteen-year-old girl with a 53° lumbar curve and a 30° thoracic idiopathic curve preoperatively. Fig. 1-B Radiographs made three weeks after surgery. Fig. 1-C Radiographs made twenty-three years after surgery.

    Algorithm for patients included in the study. VBS = vertebral body stenting and BKP = balloon kyphoplasty.

    Figure Description
  • Anchor for JumpFig. 1

    Hematoxylin and eosin-stained sections of control (Figs. 1-A and 1-B) and experimental (Figs. 1-C and 1-D) nerves three weeks after placement of rhBMP-2. Lower-magnification images showed normal fascicular structure with perineurium separating the fascicles and epineurium surrounding the nerve. Blood vessels of various sizes can be seen within the epineurium and within some fascicles. Higher-magnification images demonstrate both transverse and longitudinally oriented nerve fibers. The appearance of control and experimental tissues was similar in the one-week group. One rat in the three-week group (Figs. 1-E and 1-F) showed focal neuronal degeneration with homogenization of the nervous tissues (asterisk). This same rat demonstrated solid myelin sheaths without axons in toluidine blue-stained sections (see Figs. 3-G and 3-H). Scale bar = 200 μm in Figs. 1-A, 1-C, and 1-E. Scale bar = 50 μm in Figs. 1-B, 1-D, and 1-F.

    Figure Description
  • Anchor for JumpFig. 2

    Three-dimensional bone models at five instants of the flexion cycle from a representative control subject. Sagittal views are above, and coronal views are below. Intervertebral kinematics were determined for each pair of adjacent vertebrae (superior bone motion relative to immediately inferior bone) with use of coordinate systems embedded within each vertebral body.
