Two different types of self-tapping and self-drilling screws are available:

• a “3A” screw with differential pitch that is self-tapping, self-drilling and self-compressing,
• a “percutaneous” screw with continuous thread that is self-tapping and self-drilling but does not provide compression.

The same screws are used to fix metatarsal and phalangeal osteotomies.

• Treatment of hallux valgus of the 1^st ray (big toe) with compressive fixation, following distal and proximal metatarsal and phalangeal osteotomies
• Compressive fixation of multiple forefoot fractures.

• Made of biocompatible titanium alloy (TA6V4),
• Screws are supplied in sterile individual packs,
• Available in two diameters: Ø2.5 mm (pink anodizing) and Ø3 mm (blue anodizing).
