Therapeutic attitudes when faced with ruptures of the Achilles tendon usually oscillate between two well-known principles:

   - Non-operative orthopaedic treatment,
   - Surgical treatment.

Situated midway between these two solutions, percutaneous tenosynthesis of the Achilles tendon seems to enable the deficiencies and risks caused by the two solutions mentioned above to be avoided.
When developing this technique, the aim was to simplify the operation and provide minimum aggression.

The equipment comprises the following elements:

A polyester reinforcement thread 1.4mm in diameter and with a useful length of 80cm with specially designed needles crimped to each end.
Please note: the needle/thread crimping force is more than 8kgf (Standards: 4 kgf)
High mechanical resistance thread:

   - Rupture point under traction between the jaws: 63 daN
   - Extension to rupture: 22 %

A straight needle that, because of its length of 15cm, enables an incision to be made in an area far enough away from the rupture.
The needle’s point is triangular, with a 20° curve and ground as a trocar. There is a flat spot on the needle’s shank to give the needle carrier a better grip.
The needle can be shaped according to the curvature encountered.

A 3/8^e curved needle with an atraumatic trapezoidal section. The needles point is ground for two faces.

A high-density polyethylene pad providing excellent pressure distribution because of its convex supporting surface during final tying.
Use of this is particularly indicated if ablation of the LIGADON is envisaged.
