A modified drill guide for the anterior cervical fusion (Cloward) procedure. Technical note

Area of Science:

• Orthopedic Surgery
• Surgical Instrumentation

Background:

• Anterior cervical fusion requires precise drilling for optimal outcomes.
• Existing drill guides may lack real-time visual feedback and adaptable fixation.

Purpose of the Study:

• To introduce a modified drill guide designed to enhance the drilling phase of anterior cervical fusion.
• To improve procedural control and safety through enhanced visualization and mechanical features.

Main Methods:

• Development of a novel drill guide incorporating an inspection port for interbody hole visualization.
• Integration of adjustable fixation points and variable diameter locking rings.
• Surgical simulation or cadaveric study to evaluate the modified drill guide's performance.

Main Results:

• The modified drill guide allows direct inspection of the interbody hole during drilling.
• Enhanced mechanical features provide improved fixation stability and adaptability.
• The device facilitates simplified and more controlled execution of the drilling component.

Conclusions:

• The modified drill guide represents a significant advancement in anterior cervical fusion instrumentation.
• This improved device has the potential to enhance surgical efficiency and patient safety.
• Further clinical studies are warranted to confirm the benefits in practice.
