Summary
This review compares vertebral body replacement implants used in spinal surgery, detailing the evolution from bone grafts to modern PMMA and titanium devices. It evaluates current expandable and non-expandable options, highlighting their pros and cons.
Area of Science:
- Spinal Surgery
- Biomedical Engineering
- Orthopedic Implants
Background:
- Vertebral body replacement (VBR) has evolved significantly over 50 years.
- Initially relying on bone grafts, VBR now utilizes advanced prosthetic materials.
- Corpectomy with VBR is a standard spinal reconstructive procedure.
Purpose of the Study:
- To review and compare available vertebral body replacement implant systems.
- To analyze the advantages and disadvantages of various VBR implant types.
- To provide an overview of current VBR methods in spinal surgery.
Main Methods:
- Literature review of vertebral body replacement techniques and implants.
- Comparative analysis of different implant materials and designs (e.g., PMMA, titanium).
- Evaluation of expandable versus non-expandable implant systems.
Main Results:
- Evolution from bone grafts to PMMA and titanium implants.
- Availability of diverse expandable and non-expandable VBR options.
- Continued justification for numerous implant designs in clinical practice.
Conclusions:
- A wide array of VBR implants are currently available and clinically relevant.
- Understanding the specific advantages and disadvantages of each implant type is crucial.
- The selection of VBR implants depends on surgical goals and patient factors.
