C2 intralaminar screw placement: a quantitative anatomical and morphometric evaluation.
AIM To investigate the feasibility of placing a screw in the C2 lamina and evaluate the reliability of the surface of the dorsal arch of C2 as a landmark for determining the optimal site of screw entry. MATERIAL AND METHODS 88 adult human C2 spines were used. Seven measurements were determined for screw entry points, trajectories, and lengths for placement of intralaminar screws. RESULTS Th...
متن کاملA biomechanical comparison of a novel thoracic screw fixation method: transarticular screw fixation vs traditional pedicle screw fixation.
BACKGROUND Transarticular screw fixation is used in the upper cervical and lumbar spine to achieve posterior spinal stability, and its biomechanical performance has been proven to be similar to that of pedicle screw fixation. However, few studies have reported the use of transarticular screw fixation in the upper thoracic spine. OBJECTIVE To biomechanically compare transarticular screws with ...
متن کاملTranslaminar Facet Screw Fixation
Although the new era in spine surgery is highly focused on preserving mobility, fusion is still an accepted way of treatment for a variety of spinal disorders. To stabilize the spine until a fusion consolidates, spine surgeons have used combinations of hooks, wires and pedicle screws. The main problem with these implants is the need for an extensive soft tissue dissection which potentially cont...
متن کاملTranslaminar Facet Screw Fixation
Introduction Lumbar fusion has proven to be an accepted treatment for a variety of indications. Pedicle screw fixation has historically been the gold standard for providing stabilization to the lumbar motion segment while the fusion matures. However, numerous studies have reported high complication rates, increased pain, and juxtalevel degeneration due to the size of the pedicle screw instrumen...
متن کاملBilateral Three-Level Lumbar Spondylolysis Repaired by Hook-Screw Technique
We report a case of bilateral three-level lumbar spondylolysis that was directly repaired by use of hook-screw technique. The patient complained of low back pain for 2 years that progressively worsened and was exacerbated with standing and walking. He also mentioned bilateral sciatalgia. The neurological examination was normal. Interestingly, we found bilateral lumbar spondylolysis in L3, L4, a...
