What Makes PEEK Cages Ideal for Spinal Implants

You want spinal implants that are strong, safe, and comfortable. Peek cages are special because they are flexible like bone. They are safe for the body and easy to see on scans. A peek spinal cage is stiff like your own bone. This helps lower stress on your spine. Peek lets doctors see healing after surgery with clear images. The peek cage helps bones grow together by acting like a bridge. These cages keep the spine stable and keep patients feeling well. XC Medico’s peek cage gives good results every time you use it.

Key Takeaways

  • PEEK cages bend like bone. This helps lower stress on the spine. It also helps bones heal better.

  • These cages do not block X-rays. Doctors can see healing bones clearly in scans.

  • PEEK cages are safe for the body. They cause fewer problems after surgery.

  • Using PEEK cages can mean less pain for patients. People may heal faster and need fewer surgeries again.

  • PEEK cages work well for many spine surgeries. They help in cervical and lumbar fusions. They give strong support and keep the spine stable.

What Is a PEEK Cage

You might ask why peek cages are used in spine surgery. A peek cage is a device made from polyether ether ketone. Surgeons put these cages in your spine during surgery. Peek is flexible like bone, so it can bend and move. This helps your spine feel less stress and makes healing easier. Peek cages are safe for your body. They do not cause bad reactions. Peek is radiolucent, so doctors can see your healing on scans.

Common Types and Uses

Peek cages have different shapes and sizes for your spine. XC Medico’s Peek Cage fits both neck and lower back. There are TLIF, PLIF, and cervical cages with locking screws. These cages work as spinal cages and interbody cages. Surgeons use them in many spine surgeries. Peek cages help with:

  • Spinal stenosis

  • Degenerative disc disease

  • Degenerative scoliosis

  • Degenerative spondylolisthesis

  • Spine fractures

Peek cages are popular around the world. In 2024, they make up about 47% of the spinal surgery market. People like them because they work well and give good results.

Role in Spinal Fusion

Peek cages are important in spinal fusion surgery. The surgeon puts a peek cage between two bones in your spine. The cage holds the bones together while they heal. This helps your spine stay stable and eases pain. Peek cages help bones grow and let doctors see your healing. XC Medico’s Peek Cage follows strict safety rules in big healthcare markets, as shown below:

Peek cages are a good choice for spinal fusion and other spine surgeries. They help you feel better and get back to your normal life.

Key Properties of PEEK Spinal Cage

Key Properties of PEEK Spinal Cage

Bone-Like Modulus

You want your spinal implant to feel normal. Peek is flexible like your bone. This is called modulus of elasticity. Peek cages give support that is not too hard or too soft. This helps lower stress on your bones and joints. Surgeons pick peek because it acts like bone when you move and heal.

Here is a table that shows how peek and bone compare:

Material

Elastic modulus (GPa)

Cancellous bone

3.78

Cortical bone

14.64

PEEK

3.84

Peek’s elastic modulus is close to cancellous bone. Your body accepts the cage more easily. You feel less pain, and your spine heals better. Doctors see good results when the implant works with your body.

Radiolucency Benefits

After surgery, your doctor checks your spine’s healing. Peek is radiolucent, so it does not block X-rays or CT scans. You get clear pictures, so your doctor sees bone growth and cage position. This helps your care team find problems early and watch your progress.

Here is a table that compares peek cages and metal cages:

Feature

PEEK Cages

Metal Cages

Radiolucency

Yes, causes no distortion in imaging

No, can obscure imaging clarity

Tissue Reaction

Mild fibrous tissue reaction

Varies, often more inflammatory

Evaluation of Cage Position

Difficult due to lucency

Easier due to visibility

Peek lets your doctor see the bone healing around the cage. This makes follow-up visits more helpful. You get better care, and your doctor can act fast if you need help.

Biocompatibility and Healing

Peek is safe for your body. Surgeons trust peek cages because they do not cause bad reactions. Your body accepts peek, so you heal faster and with fewer problems. Studies show peek helps bone grow and helps spinal fusion. Doctors see good results in short and long-term checkups.

Here are some study findings:

You want to heal smoothly. Peek cages help you recover. Expandable cages, including peek, help keep your spine in the right shape after surgery. Studies show these cages can lower surgery time and blood loss. You spend less time in the hospital and get back to your life faster.

  • Patients with peek cages often have:

    • Less pain after surgery

    • Faster return to daily life

    • Fewer problems with swelling or infection

    • Good results for a long time

Doctors use peek cages because they trust them. You get a strong, safe, and comfortable choice for your spine.

PEEK Cage vs. Other Materials

Titanium Comparison

You might ask how peek cages are different from titanium cages. Titanium cages have been used for a long time. They are very strong and last a long time. But titanium can make scans hard to read. Doctors may see strange marks on images. This makes it tough to check if you are healing. Peek cages give clear scans with no strange marks. Your doctor can see bone growth and where the cage is.

Cage Type

Imaging Clarity

Artifacts

PEEK

High clarity, no artifacts

None

Titanium

Lower clarity, artifacts

Yes

Peek cages and titanium-coated peek cages have similar fusion rates. You can see this in the table below:

Cage Type

Fusion Rate (%)

Significance (p-value)

PEEK

86

0.59

Titanium-Coated PEEK

82


Titanium cages sink into bone less than peek cages. This happens at both 8-12 weeks and 52 weeks. Sinking is called subsidence. Subsidence can make the cage less stable.

Ceramic and Allograft Alternatives

Ceramic and allograft cages are other choices for spine surgery. Ceramic cages cost less than peek cages and allografts. Allografts cost the most. Peek cages save money compared to allografts. Peek cages bend like human bone. This helps stop sinking. Ceramic cages may help bones grow together better. But peek cages feel better and give clearer scans.

  • Ceramic cages cost the least.

  • Peek cages save more money than allografts.

  • Peek cages help stop sinking because they bend like bone.

Unique Advantages of PEEK

Peek cages have special benefits. Peek bends like your bone. This lowers stress and sinking. Peek is radiolucent, so doctors see clear scans after surgery. You get better checkups. Peek cages are safe for your body. Your body accepts them well.

Tip: Peek cages help your doctor see healing and fusion with clear scans. You get a safer and more comfortable recovery.

Peek cages work as spinal cages and interbody cages. They hold your spine and help bones grow together. You get strong support and better results after spine surgery.

Clinical Applications in Spinal Surgery

Posterior Cervical Fusion

If your neck disc is hurt, you might need surgery. Doctors use cervical peek cages for a type of neck fusion. These cages help keep your neck steady and help bones grow. The doctor takes out the bad disc and puts in a cage with bone graft. The cage acts like a bridge for new bone to grow. Peek cages are strong and safe for your body. They also let doctors see clear scans. This makes peek cages a good choice for neck surgery. You can see how well peek cages work in the table below:
