STUDY DESIGN Computerized tomography (CT) of the lumbar spine cadaveric specimens was used to evaluate the effect of increasing the height of the disc space in the lumbar spine to the facet joint articulation in the sagittal plane. OBJECTIVE To show how the facet joint articulation is affected by increasing the height of the disc space in the lumbar(More)
BACKGROUND CONTEXT Transarticular C1-2 screws are widely used in posterior cervical spine instrumentation. Injury to the vertebral artery during insertion of transarticular Cl-2 screw remains a serious complication. Use of a computer-assisted surgery system decreases this complication considerably. However, this system encounters problems in ensuring(More)
A fracture of the posteromedial talar tubercle is also referred to as the Cedell fracture and is an infrequently described injury. Failure to recognize this injury may lead to posteromedial ankle pain and tarsal tunnel syndrome. It is therefore important to diagnose these fractures at the time of the initial presentation to avoid future morbidity. Although(More)
Vascular injury may be encountered during an anterior approach to the pelvis or acetabulum—be it due to hematoma decompression, clot dislodgement during fracture manipulation, or iatrogenic. This can be associated with significant bleeding, hemodynamic instability, and subsequent morbidity. If the exact source of bleeding cannot be easily identified,(More)
Introduction Ligamentotaxis is the application of axial tension to reduce and hold distal radius fractures through the extrinsic ligaments of the wrist. Longitudinal, external traction applied with a wrist external fixation device may also utilize the principle of the ligamentotaxis. Kaempffe et. al. has shown that as duration of distraction across the(More)
Lumbar discography, a useful modality for evaluating patients with lower back pain, is performed under fluoroscopy with posteroanterior and lateral fluoroscopic imaging. Despite use of fluoroscopy, needle placement into the L5-S1 disc may be difficult, especially in the presence of degenerative changes. We describe use of angled posteroanterior fluoroscopy(More)
