Expandable Titanium Cage for Spinal Reconstruction
An expandable titanium cage is a specialized spinal implant designed to restore anterior column stability following vertebral body loss. By allowing controlled in-situ expansion, the expandable titanium cage enables precise height restoration while minimizing endplate damage and surgical trauma.
What Is an Expandable Titanium Cage in Spine Surgery
An expandable titanium cage is an adjustable interbody or vertebral body replacement device used in spinal reconstruction procedures. Unlike static cages, the expandable design allows surgeons to insert the cage at a reduced profile and then expand it gradually to achieve optimal fit and spinal alignment.
What are the types of Expandable Titanium Cage？
There are several types of expandable titanium cages used in spinal surgery, and the specific types may vary depending on the manufacturer. However, here are some common types:
Expandable TLIF Cage:
This type of cage is used in transforaminal lumbar interbody fusion (TLIF) procedures, which involve removing the intervertebral disc and inserting a cage to stabilize the spine. The expandable TLIF cage can be adjusted to fit the specific anatomy of the patient and provide optimal support.
Expandable PLIF Cage:
Similar to the TLIF cage, the expandable PLIF cage is used in posterior lumbar interbody fusion (PLIF) procedures. This type of cage can be expanded in height, width, and lordosis to provide a customized fit and better fusion outcomes.
Expandable Cervical Cage:
This type of cage is used in anterior cervical discectomy and fusion (ACDF) procedures, which involve removing a damaged disc and replacing it with a bone graft and cage. The expandable cervical cage can be expanded in both height and lordosis to provide a better fit and support for the cervical spine.
Expandable Corpectomy Cage:
This type of cage is used in corpectomy procedures, which involve removing a vertebral body and replacing it with a cage. The expandable corpectomy cage can be adjusted to fit the specific anatomy of the patient and provide better support for the spine.
Clinical Role of Expandable Titanium Cage After Corpectomy
After partial or total corpectomy, the expandable titanium cage serves as a load-bearing implant that restores vertebral height, maintains spinal alignment, and provides a stable environment for bone fusion. It plays a critical role in anterior column reconstruction.
Indications and Surgical Applications of Expandable Titanium Cage
Expandable titanium cages are indicated for spinal reconstruction in thoracic, lumbar, and selected cervical cases. Common indications include spinal trauma, tumor resection, vertebral infection, and severe degenerative conditions requiring vertebral body replacement.
Design Features of Expandable Titanium Cage System
The expandable titanium cage system features a controlled expansion mechanism that allows precise intraoperative height adjustment. A large central graft window facilitates bone graft packing, promoting osseointegration and long-term fusion stability.
Material Advantages of Titanium Alloy Expandable Cage
Manufactured from medical-grade titanium alloy, the expandable titanium cage offers high mechanical strength, excellent biocompatibility, and compatibility with CT and MRI imaging. The surface characteristics support bone ongrowth and biological fixation.
Surgical Benefits of Expandable Titanium Cage vs Static Cage
Compared with static cages, expandable titanium cages reduce the risk of over-distraction and endplate collapse. The gradual expansion process improves sagittal alignment restoration and enhances overall construct stability.
Compatibility with Posterior Fixation Systems
Expandable titanium cages are designed for use in combination with posterior pedicle screw and rod fixation systems. They are suitable for anterior, posterior, or combined surgical approaches, offering flexibility for complex spinal reconstructions.
