Cervical CT-guided, selective nerve root blocks: improved safety by dorsal approach

Area of Science:

• Pain Management
• Interventional Radiology
• Neurosurgery

Background:

• Cervical radicular pain is commonly treated with cervical transforaminal blocks.
• Current techniques primarily utilize fluoroscopic guidance, with CT-guided approaches also described.
• Optimizing needle placement for enhanced selectivity and efficacy is an ongoing area of research.

Purpose of the Study:

• To describe a modified technique for cervical nerve root blockade.
• To achieve an extraforaminal needle placement.
• To ensure selective nerve root block comparable to transforaminal approaches.

Main Methods:

• Description of a modified cervical nerve block technique.
• Guidance method (fluoroscopy or CT) not specified for the modified technique.
• Focus on achieving extraforaminal needle positioning relative to the neural foramen.

Main Results:

• The described modification results in an extraforaminal needle position.
• The technique provides an equally selective nerve root block.
• Comparison of the modified extraforaminal approach to the traditional transforaminal approach.

Conclusions:

• A modified extraforaminal approach can achieve selective cervical nerve root blockade.
• This technique offers an alternative to standard transforaminal blocks.
• Further studies may be warranted to compare clinical outcomes and safety profiles.
