• PROTEOR activité

  • Appropriate for trans-tibial amputees with short stumps
  • Its J-shape design reduces strains in the socket
  • Optimum possibility of accommodating various situations

Dyna J is a foot made in composite material with a long J-shaped shank.

Dyna J provides a smooth step completion, which reduces patient's fatigue in everyday life and leisure sport activities, even at a high level. As energy is stored when warping of the shank and keel at heel strike, it is smoothly released at toe off.

• Thanks to its J shape and its upper connectors close to its distal part, Dyna J ensures an optimal distribution of the weight and reduces the strains in the socket.

• Lateral stability due to the large bearing surface at the fore-foot : 48 mm width close to that of a sound foot.
• Dynamic effect increased by the long plantar keel. The effective foot length of the Dyna J foot amountsto 80% of its total length, versus 83% for a sound foot.

• The split plantar keel provides inversion/ eversion that accommodates uneven grounds more easily.

• Delivered in kit with its cosmetic shell, a protective sock, a malleolar clip, adhesive, a bushing and screws. The foot
can accurately suit the patient's needs through optimization of height and alignment.
