Otto Bock 17B105 Instructions For Use Manual page 8

INFORMATION
These Titanium System Knee Joints are designed to be used together with
free-motion or dorsiflexion assist ankle joints. Please note: combining this
product with ankle joints having a dorsiflexion stop increases stresses on the
entire orthosis and results in increased wear and tear on the components.
The remote cable-release should only be used in combination with the
integral Cable Housing (as delivered.) Refer to 5. Maintenance.
2 Indications for use
Partial paralysis or complete paralysis of the lower limb musculature. Spe-
cific indications must be determined by the physician.
