What Are Spinal Fusion Screws?
Spinal fusion screws are special tools used to keep vertebrae stable during fusion. They are key in many spinal surgeries. They help the bones grow together by keeping the vertebrae still.
Definition and Purpose
These screws, also called pedicle screws, help in fusion surgery. They keep the spine stable and stop movement at a joint. This helps bones heal and reduces pain.
Materials Used
These screws are made from materials like titanium and PEEK. These materials are strong, last long, and don’t corrode. They also don’t get rejected by the body, making them safe for a long time.
Types of Spinal Fusion Screws
There are many kinds of spinal fusion screws for different needs:
- Pedicle Screws: These screws go into the vertebra’s pedicles for strong support.
- Cortical Screws: These screws are for cortical bone and are very strong. They’re used in less invasive surgeries.
- Cannulated Screws: These screws have a hole for a guide wire. This helps place the screw exactly right during surgery.
Here’s a look at the different types of spinal fusion screws:
| Type of Screw | Application | Advantages |

Procedure Overview
The spinal fusion procedure is a complex surgery. It aims to make the spine stable by joining two or more vertebrae together. This is often needed for serious spinal problems like scoliosis, spinal stenosis, or degenerative disc disease. Orthopedic surgeons are experts who use special techniques for each patient.
Surgical Techniques
There are several ways to do a spinal fusion surgery. Each method is chosen based on the spinal issue and the patient’s needs:
- Anterior Approach: This method goes through the front of the spine, through an incision in the belly.
- Posterior Approach: This is the most common way to access the spine from the back.
- Lateral Approach: This method comes from the side, and is used for lower spine problems.
Role of Spinal Fusion Screws
Spinal fusion screws are key to a successful surgery. They are put into the vertebrae to hold metal plates or rods in place. These screws help keep the spine stable and in the right position while it heals.
Postoperative Care
After surgery, taking good care of yourself is very important. This helps you heal well and lowers the chance of problems. Important steps include:
- Pain Management: Using medicines and other ways to control pain.
- Wound Care: Keeping the surgery area clean to stop infection.
- Movement Restrictions: Following rules about how much you can move to protect your spine.
After surgery, going to Physical therapy and slowly getting back to normal activities is key. This helps you heal better and get back to your life faster.
| Surgical Technique | Access Point | Common Uses |
|---|---|---|
| Anterior Approach | Through the abdomen | Degenerative disc disease, scoliosis |
| Posterior Approach | Through the back | Spinal stenosis, herniated discs |
| Lateral Approach | Through the side | Lower spine conditions |
