Final answer:
Pedicle screws are used to correct spinal degeneration. These are specifically designed for spine-related conditions to provide fixation and stabilize the spine.
Step-by-step explanation:
Pedicle screws are commonly used in spinal surgeries. They are specifically designed for conditions related to the spine, such as correcting spinal degeneration, deformities, and instabilities. Therefore, out of the options given, pedicle screws are used to correct C. Spinal degeneration. These screws are placed through the pedicle portion of the vertebrae and into the vertebral body to provide fixation and stabilize the spine.
For other conditions listed:
- Anterior dislocations typically involve the relocation of the dislocated bone and sometimes the use of slings or specific exercises rather than pedicle screws.
- Femoral fractures are more likely to be treated with intramedullary rods and screws within the bone marrow space of the femur.
- Pelvic fractures may require external fixation or screws, but not specifically pedicle screws, as these are intended for spinal use.
