Blatchford · Hydraulic ankle feet · PR-007
The Blatchford AvalonK2 hydraulic ankle prosthetic foot brings hydraulic ankle motion to limited community walkers. The ankle allows 6 degrees of plantarflexion and 6 degrees of dorsiflexion, and the keel is shaped for the slower walking pace typical at activity level 2. It carries users up to 330 lb and can be submerged to 1 m.
For lower-activity K2 walkers who move around the home and local area and would like the foot to settle on ramps and uneven surfaces. A prosthetist assesses suitability, fits and aligns it.
This kind of device is prescribed and fitted by a clinician. An enquiry starts that conversation. It is not a purchase.
