Take advantage of patented Auto-Compression™
Hallux valgus with arthritis and hallux rigidus are two of the most common conditions that require MTP-1 arthrodesis. Arthrodesis with two crossing interfragmentary screws is a common surgical method.
With the partially threaded ActivaScrew™ Cannulated LAG, you get an excellent compression supported by patented Auto-Compression™ with the advantages of the bone replacing the implant after healing.

The fixation of MTP-1 arthrodesis should be reproducible, lead to a high rate of fusion and have a low incidence of complications. MTP-1 arthrodesis with two ActivaScrew™ Cannulated bioabsorbable screws create extra compression force to the fixation by the patented Auto-Compression™. The extra compression supports the fixation for at least 8 weeks. After the healing, bone naturally regains its strength without stress shielding.

Why this technique?
The patient avoids long-term complications and hardware removal.
After the healing, bone replaces the implant. This is done without stress-shielding, a loss of bone strength which is a characteristic of metal implants.
You can achieve good compression to the fixation area, as the implant offers added compression by shortening lengthwise 1-2 % in human body conditions.
