The Nancy and ECMES Nails Philosophy
Elastic Stable Intramedullary Nailing (ESIN) is an established philosophy for treatment of long bone
fractures in children. Pioneered at the Hopital des Enfants in Nancy, France, ESIN relies on the
flexibility of Titanium to provide a stable reduction and dynamisation of long bone fractures in
children. ESIN uses Two Small Diameter Titanium Nails which are pre-bent and inserted in
either a retrograde or antegrade fashion into the fractured bone.
M/L Stability (Figure 1)
The Bend in the nails causes the nails to act as springs which
stabilise the two bone fragments in the medio-lateral plane.
Axial and Rotational Stability (Figure 2)
Figure 1
The Sharp Flattened Extremities penetrate the distal or proximal
cancellous bone to provide both axial and rotational stability to the
bone fragments.
Figure 2
Minimally Invasive Approach (Figure 3)
The Small Diameter of the nails (maximum 4 mm) allows for a
minimally invasive approach (2 cm incision).
Figure 3
Continuous Dynamisation (Figure 4)
Titanium provides flexibility to the nails, thus allowing continuous
dynamic loading of the fracture site.
The Results
These design and biomechanical factors combine to benefit the
child by enabling:
• Early Weight Bearing
• Rapid Return to Normal Activities
