Summary
Threaded cortical bone dowels offer an osteoconductive solution for lumbar fusion stabilization. This review details their history, preparation, and clinical safety and efficacy in spinal fusion surgery.
Area of Science:
- Spinal Surgery
- Biomaterials
- Orthopedics
Background:
- Lumbar fusion is a prevalent spinal procedure requiring segment stabilization.
- Threaded cortical bone dowels are advanced bone allografts designed for this purpose.
- These dowels possess osteoconductive properties and can be augmented with bone grafts or growth factors.
Purpose of the Study:
- To provide a comprehensive review of threaded cortical bone dowels.
- To cover their history, preparation, and applications in spinal fusion.
- To evaluate their safety and efficacy in lumbosacral interbody fusion.
Main Methods:
- Literature review of existing studies and clinical data.
- Analysis of the preparation and material properties of threaded cortical bone dowels.
- Examination of clinical outcomes, including safety and efficacy data.
Main Results:
- Threaded cortical bone dowels have been clinically utilized for over five years.
- The review synthesizes information on their development and application.
- Data on their safety and efficacy in lumbosacral fusion is presented.
Conclusions:
- Threaded cortical bone dowels represent a significant development in spinal fusion devices.
- Their osteoconductive nature and potential for augmentation enhance fusion outcomes.
- This review establishes a foundation for understanding their role in lumbosacral interbody fusion.
