Calcanail for calcaneal fracture and subtalar arthrodesis

A through-the-heel approach should 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 with the CALCANAIL® nail.

– 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
– Subtalar arthrodesis following intra-articular calcaneal fracture (subtalar osteoarthritis and malunion)
– Degeneration of the subtalar joint or pes planus

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

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