ActivL and M6L difference
 

Hey ADR Peeps, what is the difference between the ActL device and the M6L device? Can anybody comment with what they know please.

Main difference is constrained device(ActivL) versus non-constrained or semi-constrained(M6). Also, alloy materials. CoCroMo (Activ) versus titanium(M6).

Movement is different also on axis of rotation.

Drewrad,
Thx for you posted response.

So if I understand your post it would mean constrained motion within the degrees of motion of the disk?

Maczoid

M6 constrains on axial rotation and has translation on forward flexion as well as extension and is not 'locked into' a path of travel.

Activ L has an insert which allows for translation but is locked into a path of travel.
