High Strength Cannulated Titanium Bar for Trauma Surgery

Trauma surgery deals with broken bones. High energy injuries. Car crashes. Falls. The bone is fractured. Needs hardware to hold it.

High strength cannulated titanium bar for trauma surgery is the starting stock for that hardware. Hollow bar, not solid. Goes over a guide wire. The wire goes first. X-ray confirms position. Then the implant follows.

Cannulated hip screws. Cannulated IM nails. Trauma screws for wrist and ankle. Any trauma implant that needs high strength and guide wire placement.

Trauma surgery is often minimally invasive now. Small incision. The surgeon can't see the bone directly. X-ray guides the way.

Guide wire goes in first. X-ray from two angles. Position looks good. Then the cannulated implant slides over the wire. No guessing. No malalignment.

For high strength cannulated titanium bar for trauma surgery, the inner hole makes this possible. The outer wall provides the strength to hold bone.

Trauma implants take high loads. The patient may bear weight early. The bone is broken. The implant carries the load.

Grade 23 ELI is the standard for trauma. ASTM F136 medical grade. High strength allows thinner wall. Smaller outer diameter. Less implant in the bone.

For high strength cannulated titanium bar for trauma surgery, Grade 23 ELI is the only choice.

Chemical limits

No nickel. Medical implant grade.

Wall thickness from 1.0mm for screws to 3.5mm for large nails.

• Cannulated hip screw. Femoral neck fracture. Most common trauma implant. Guide wire through the femoral neck into the head. Cannulated screw slides over. Compresses the fracture. Patient bears weight in weeks.

• Cannulated IM nail. Femur. Tibia. Humerus. Long bone fractures. Guide wire down the medullary canal. Cannulated nail follows. Locking screws at both ends.

• Cannulated trauma screws. Wrist. Ankle. Smaller fractures. 4.0mm to 5.0mm outer diameter. Thin wall. High strength.

For high strength cannulated titanium bar for trauma surgery, each implant sees high cyclic loads. Walking. Stairs. The bar must have good fatigue life.

Trauma implants use thicker guide wires. 2.5mm to 3.5mm.

Clearance must be enough for smooth sliding. Not too much wobble.

Trauma implants are often long. A femoral nail is 400mm. Straightness is critical. Bent nail won't pass.

Thinner wall means smaller outer diameter for the same inner diameter. Less bone removed. Better bone preservation.

But wall must be thick enough for the load.

Grade 23 ELI's high strength allows these thin walls. Grade 4 pure titanium would need thicker wall. Bigger implant.

Trauma implants cycle. Patient walks. Bone heals slowly. The implant sees millions of cycles before full healing.

Grade 23 ELI fatigue limit: 500-600 MPa at 10^7 cycles. Our cannulated bar maintains this. No reduction from drilling.

For high strength cannulated titanium bar for trauma surgery, fatigue life is as important as static strength.

Solid Grade 23 ELI rod. Deep hole drilling. Long drill bits. High pressure coolant. Flushes chips out of the deep hole.

Multiple passes. Rough drill. Ream. Hone. Each pass improves concentricity and surface finish.

Centerless grinding. Outer diameter ground to tolerance. Uses inner bore as reference. Concentricity maintained.

Straightening. Slow pressure. No damage to inner bore.

Final inspection. Camera down every bar. Check for burrs. Check for steps. Check for smoothness.

For high strength cannulated titanium bar for trauma surgery, the process is specialized for long, small-diameter tubes.

Trauma implants contact bone and soft tissue. Smooth surface reduces friction during insertion.

Polished outer surface. Ra ≤ 0.2μm.

Inner bore also polished. Ra ≤ 0.2μm. Guide wire slides smoothly.

IM nails need holes for locking screws. Drilled after cannulation.

Cross holes. The cannulation must not deform during drilling. Our hollow bar maintains roundness. No oval shape. No wall collapse.

Trauma implants are Class III medical devices. Full traceability required.

Every high strength cannulated titanium bar for trauma surgery comes with:

Heat number. Mill test report. ASTM F136 cert. Chemical analysis. Mechanical test results. Concentricity report. Inner diameter cert.

EN 10204 3.1 standard. 3.2 available with third-party witness.

Trauma surgery needs strong implants that go over guide wires. Accurate placement. Minimally invasive.

High strength cannulated titanium bar for trauma surgery gives you that.

Grade 23 ELI. ASTM F136. 860 MPa tensile. Good fatigue life.

4.0mm to 15.0mm outer. 2.0mm to 8.0mm inner. Concentric. Straight. Polished.

For hip screws. For IM nails. For trauma screws. For long bone fractures.

Strong enough for body weight. Hollow enough for guide wires. Reliable for trauma.
