Calcanail for calcaneal fracture and subtalar arthrodesis

Minimally invasive approach at the posterior calcaneal tuberosity avoids complications associated with the standard lateral approach.

Locking nail holds the posterior talar articular surface in the proper position after intrafocal reduction.

Option to convert from fracture fixation procedure to subtalar arthrodesis.


A through-the-heel approach is to be used, using a hollow reamer to tunnel into the calcaneus. When used with a subtalar distractor, this method provides direct intrafocal access to the joint fragments.

This technique makes it possible to correct tuberosity displacements and to obtain good joint reduction in large intra-articular fractures with large fragments or to perform arthrodesis straightaway in cases of more complex intra-articular fractures.

The reduced joint and calcaneus are held in place by percutaneous fixation nail, the CALCAnail®.


– Minimally invasive technique: closed reconstruction of foot anatomy with a nail and cannulated screws
– Innovative reduction technique that reduces surgical trauma and the risk of complications
– Large bone plug removed when work chamber is created can be used as autograft
– Intrafocal reduction of displaced intra-articular fragments is easier when using a Caspar-type subtalar distractor
– Placement of locking nail under joint surface is held at the correct height
– Placement of bone graft into implant windows helps with bone union

Option to perform subtalar arthrodesis using same approach and instrumentation (12 mm nail instead of 10 mm)

Material: titanium


– Displaced intra-articular fractures of the calcaneus

– Subtalar arthrodesis following comminuted fractures of the calcaneus, posttraumatic osteoarthritis and/or poor function resulting from calcaneal fracture sequelae, osteoarthritis of the subtalar joint, or valgus flatfoot deformities


Fracture nail:
Ø 10 mm / length 45 mm, 50 mm and 55 mm

Arthrodesis nail:
Ø 12mm / length 65 mm, 75 mm, 85 mm
