Titanium Polyaxial Lumbar Pedical Screw for M5 Spinal Fusion Surgery Screws
Pedical screws are made from titanium alloy material and harden grade TC 4 , normally , titanium pedical screw hardness is HRC 30 or so , but it will up to HRC 45 after hardening or higher compared to unhardening . it is very strong than other common materials . this is why titanium pedical screws can be used for bodies that have to bear heavy duty in medical surgery like lumbar or feet etc . Besides , titanium pedical screws are resistant corrosion well .
Pedical screws have a polyaxial head design that is quite easy to be moved or rotated in bone joints . tapping threads with sharp point can drill into bone to support head moving and rotating under polyaxial design .
