Advanced solutions
Distal and Talar Locking Options Screw orientation options: – Calcaneus into the cuboid – Talus into the navicular

Spiral Blade – Increased surface area optimizes load distribution in the calcaneus – Lengths: 45 mm – 100 mm (5 mm increments) – Cannulated for insertionover a 3.2 mm guide wire – 12.5 mm blade diameter – Front cutting end – Implants common with the Expert Retrograde/Antegrade Femoral Nail System – Titanium alloy *

Improved stability
End Caps – Securely lock spiral blade or the most distal locking screw – Prevent ingrowth of soft tissue and facilitate nail extraction – Sit flush with end of nail – Self-retaining, T25 recess for easy pickup andinsertion of end cap – Titanium alloy *

Nail Design – The lateral bend allows an entry site in the center of the lateral column of the calcaneus – Permits proper hindfoot alignment and restores 3°–5° valgus positioning for a better gait –Cannulated for use over all Synthes 2.5 mm or 3.0 mm ball-tipped reaming rods. Reaming rods may be removed through the nail and the insertion handle assembly (no exchange tube required) – Titanium alloy* The nail design and aiming arm enable targeted medial-to-lateral or lateral-to-medial proximal locking.

Standard Locking Screws – Double-lead threads for ease of insertion – Thread closer to screwhead for better bone purchase in the near cortex – Self-tapping blunt tip – Self-retaining, T25 Stardrive recess, improved torque transmission, increased resistance to stripping relative to a hex recess and secure locking screw pickup – 6.0 mm for distal locking options – 5.0 mm for talar and proximal locking options – Titanium alloy *

AO Principles

In 1958, the AO formulated four basic principles, which have become the guidelines for internal fixation in general 1, and intramedullary nailing in particular. The Expert Hindfoot Arthrodesis Nail enables an intramedullary approach for the fixation and the fusion of the ankle and of the subtalar joints. The system consists of a series of cannulated nails, cannulatedspiral blades, cannulated end caps and locking screws. All the implants are made of titanium alloy. Anatomic reduction Fracture reduction and fixation to restore anatomical relationships. The Expert Hindfoot Arthrodesis Nail is designed to fit anatomically in the calcaneus and distal tibial canal allowing anatomic fusion of the ankle. Stable fixation Stability by fixation or splintage, as thepersonality of the fracture and the injury requires. The Expert Hindfoot Arthrodesis Nail provides secure fixation for ankle fusions. The use of the spiral blade with end cap or the distal locking screw with end cap provides a fixed-angle construct ideal for patients with poor bone quality. Preservation of blood supply Preservation of the blood supply to soft tissue and bone by careful handling. The...
