INTRAVERTEBRAL EXPANDABLE IMPLANTS IN THORACOLUMBAR VERTEBRAL COMPRESSION FRACTURES

Area of Science:

• Orthopedics
• Spinal Surgery
• Biomechanics

Background:

• Anatomic restoration of vertebral compression fractures is crucial for optimal spinal biomechanics and function.
• Current methods may not fully achieve anatomic reduction, potentially leading to adjacent segment issues.

Purpose of the Study:

• To highlight the role of intravertebral expandable implants in achieving complete anatomic reduction of vertebral compression fractures.
• To review the biomechanics, characteristics, and indications of these implants.
• To propose an updated surgical treatment algorithm for vertebral compression fractures.

Main Methods:

• Review of biomechanical principles and implant characteristics.
• Discussion of direct and indirect fracture reduction concepts.
• Presentation of a revised surgical algorithm incorporating intravertebral expandable implants.

Main Results:

• Intravertebral expandable implants can restore vertebral endplate morphology and enable adequate disc healing.
• This technique helps prevent disc degeneration and osteodegenerative changes at adjacent levels.
• Implants facilitate fracture reduction and height maintenance, minimizing adjacent vertebral overload and fracture risk.

Conclusions:

• Intravertebral expandable implants are a highly effective option for treating vertebral compression fractures.
• Their application can significantly improve long-term spinal health and reduce secondary complications.
• An updated surgical algorithm incorporating these implants is proposed for enhanced patient care.
