A simple method for making a hollow cylindrical polymethylmethacrylate strut for cervical spinal reconstruction

Area of Science:

• Biomaterials Science
• Spinal Surgery
• Medical Device Innovation

Background:

• Anterior spinal reconstruction often requires specialized implants.
• Existing methods can be costly and may involve risks associated with human grafts.
• There is a need for accessible and affordable alternatives for spinal support.

Purpose of the Study:

• To introduce a novel, straightforward method for fabricating hollow cylindrical polymethylmethacrylate (PMMA) struts.
• To provide a cost-effective solution for perioperative anterior spinal reconstruction.
• To offer an alternative to expensive implants and human grafts.

Main Methods:

• Utilized 10-ml and 3-ml disposable plastic syringes filled with PMMA and 10% BaSO(4).
• Fabricated hollow cylindrical PMMA struts suitable for anterior cervical discectomy or corpectomy.
• Developed a process completable within 30 minutes.

Main Results:

• Successfully created PMMA struts (approx. 50 mm length, 14 mm outer diameter, 10 mm inner diameter).
• Struts are easily customizable in length and shape using basic surgical tools.
• Demonstrated significant cost reduction (at least $1000 US for a 1-level discectomy).

Conclusions:

• The described method offers a simple and rapid way to produce hollow PMMA spinal struts.
• These struts provide adequate support for anterior spinal reconstruction at a reduced cost.
• Presents a viable alternative for patients seeking affordable and safe spinal reconstructive options.
