Distal Lateral Femur Plate - Pangea

Distal Medial Femur Plate - Pangea

Distal Medial Femur Plate

Longest Pangea distal femur plates you offer is?

20 Hole

What are the lengths of the Pangea medial femur plates?

4-14 is 5.0 drill bit is 3.2 for Cortical, 4.3 for Locking

2,3,4,6 - for 3.5 drill bit is 2.5mm

Cemented hip stems, risk for peripro femur fractures higher or lower than Press Fit?

Press Fit are a higher risk for periprosthetic fractures

Fracture gaps and how that plays a role on the stress on a plate

As fracture gap increases, stress on plate increases.

Pangea overall, what drill bits go with it, small frag and large frag?

Small Frag: 2.5 for locking and non locking

Large Frag: 3.2 for cortical, 4.3 for locking

3.2 for 4.0 locking

Risk factors for non union:

Obesity

Open Fracture

Comminution

Infection

How far up should you go up the stem for a plate?

half way up the stem, you do not need to go all the way up the greater trochanter

Two cortical widths up

Locking mechanism in Pangea, and how it works?

Cobalt Chrome screws, create their own threads into the plate which is TI6Al4V

How many times you can go in and out with locking screws? 

3 times

Variable angle of Pangea locking screws?

30 Degrees

How to make an exfix more stable?

More pins —More Stable, adding additional pins to the existing frame

Adding more planes increase stiffness

Moving the rod closer to the bone

Addition additional rods (double stacking)

What is elastic deformation and what does it relate to?

Elastic deformation is how far something can go with still being able to go back to original form, this is yield strength,

What is plastic deformation and what does it relate to?

when something is stressed so far it leads to permanent deformation, this is ultimate strength
