A Cranial Internal Fixation System is a medical device system used for the stabilization and fixation of cranial bones, typically after trauma, surgery, or congenital deformities. These systems help in securely holding bone fragments or repositioned skull segments in place to facilitate proper healing.
Key Components:
1⃣ Plates – Small, thin titanium or bioresorbable plates that are contoured to fit the cranial anatomy.
2⃣ Screws – Titanium or bioresorbable screws used to secure plates to the skull bones.
3⃣ Mesh – Thin, flexible titanium or polymer meshes used in cases of larger skull defects.
4⃣ Burr Hole Covers – Circular covers designed to protect burr holes made during neurosurgical procedures.
5⃣ Instruments – Specialized tools like screwdrivers, drill guides, and forceps for precise implantation.
Common Applications:
1⃣ Cranial Trauma: Fixation of fractured skull bones.
2⃣ Neurosurgical Procedures: Post-craniotomy bone flap fixation.
3⃣ Tumor Resection Defects: Reconstruction after skull tumor removal.
4⃣ Congenital Skull Defects: Correcting conditions like craniosynostosis.
Material Considerations:
1⃣ Titanium Alloy (Ti-6Al-4V, Ti-Pure): High biocompatibility, corrosion resistance, and mechanical strength.
2⃣ Bioresorbable Polymers (PLGA, PLLA): Absorbed over time, reducing the need for removal surgery, often used in pediatric cases.
