MC-Subtalar™ II
To correct calcaneus valgus
The MC-Subtalar™ II screw system is for the correction of flexible flat feet in children (6 to < 12 years of age) and adolescents (12 to < 13 years of age) through a subtalar extra-articular screw arthroereisis. It is intended to block medial and plantar pronation of the talus with a cancellous bone screw.
Technical Specifications
- Lengths: 25 mm, 30 mm, 35 mm; head diameters of 6 mm, 8 mm and 10 mm
- Material: Stainless steel (X2CrNiMo)
- Screw inserted with a Torx (T20 star drive with), self-locking feature. Facilitated insertion through a self-drilling and self-tapping screw tip. Pilot drill usage optional
- Cannulated for guided insertion using a 1.6 mm diameter K-wire
- Screws are self-tapping/self-drilling
FEATURES
- Hexagon shaft for intraoperative correction of valgus/varus (over or under corrections) after the screw head is interlocked underneath the Processus lateralis
- Adjustment of anatomical angles with optimal ease-of-use
- Joint surfaces remain unaffected
- No post-operative rest period necessary. Partial weight-bearing without pain after a few days
- Different screw head sizes
- Reduced implant-associated complication rates such as dislocation, migration and failure compared to sinus-tarsi implants
Indications
- Flexible flat feet in children and adolescence
- Progressive medial talus protrusion
- Loss of longitudinal arch
- Pain along the Tibialis posterior
- Age > 6 years, after conservative treatment did not result in flat foot correction
- Age < 13 years, while the deformity may be corrected manually
