Tenolig

Tenolig is a percutaneous implant for acute Achilles tendon tears.

Concept

Three main techniques are used to repair ruptured Achilles tendons.

PERCUTANEOUS

This technique consists of passing two sutures with preloaded needles into which small harpoons are embedded. The entry points are about 6 cm proximal to the tear on the posterolateral side of the tendon. The exit points are on the posterolateral side of the tendon over the retromalleolar space, 4 to 5 cm below the tear.

The surgeon passes the two needles percutaneously proximal to distal, through the ruptured tendon.

The harpoons attach themselves into the upper portion of the tendon. The sutures are pulled downwards to bring the two ruptured tendon ends together, and then locked with polyethylene discs against the skin. The sutures can be removed by the surgeon after about 6 weeks.

The percutaneous technique is based on four principles.

  1. Bringing the two ruptured Achilles tendon ends together for 6 weeks without using a surgical incision. During this time, the entire tendon can be mobilised through flexion/extension movements of the foot.
  2. Not devascularising the tendon by unnecessarily opening its sheath.
  3. Preserving the post-rupture haematoma to ensure good, fast healing.
  4. Allowing early mobilisation to guide the alignment of collagen fibres and hasten their transformation into efficient elastic tendon fibres.

Successful Tenolig use requires that the surgical technique be followed and that the patient complies fully with the postoperative protocol.

CONSERVATIVE

This technique consists of using two consecutive knee-to-ankle casts:

the first with the ankle in full plantarflexion so that the two tendon ends are as close together as possible, and the second with the ankle at 90°.

STANDARD SURGERY

In this technique, the two tendon ends are sutured together through a 10 to 15 cm skin incision.

Indications

Surgical repair of an acute Achilles tendon tear using a percutaneous approach.

For the best results, this procedure should be performed within 8 days of the tear.

Features

The full kit consists of:
– a 0.85 mm diameter suture, 36 cm useful length, with a harpoon; it is preloaded with a 1.5 mm diameter, 15 cm long slightly curved cutting needle that can be reshaped intra-operatively to best match the type of tear
– a perforated metal stopper that is used to tighten the suture
– a polyethylene (UHMWPE) disc that has a flat side and a convex side that is not easily compressible by the skin

The box contains two full Tenolig kits needed for a standard percutaneous repair.
