The Hindfoot Arthrodesis Nail EXPERT System permits a proper hindfoot alignment due to a unique lateral bend of the nail along with an optimal stability provided through various locking options.

Key Features & Benefits

The lateral bend of the nail was designed to do the following:

• Restore 3 to 5 degrees of valgus positioning to improve patient’s gait
• Avoid damage to the lateral plantar artery and nerve. 

Various Locking options are available within the nail:

• Distally, the Spiral Blade increases surface area and optimizes load distribution in the calcaneus for additional stability in osteoporotic bone.
• The 6.0mm locking screws allow a posterior to anterior fixation for greater purchase in the calcaneus as well as a calcaneocuboid fusion option.   
• The appropriate endcap provides a fixed angle construct with the spiral blade and/or the 6.0mm locking screw.
• The angulated 5.0mm locking screw through the talus facilitates the subtalar fusion by additional fixation and provides an optional talar / navicular fusion. 
• Proximally, the placement of the two 5.0mm locking screws are targeted through the aiming arm, regardless of the nails length.
• The system allows different locking orientations:
  • Medial to lateral or
  • Lateral to medial
• The dynamization slot allows optional post operative compression.
