Neck Geometry Options


CORAIL Standard Stem KS and High Offset KHO stem options enable femoral offset restoration and soft-tissue tensioning.


High Offset KHO collarless option adds 7 mm of direct lateralisation to restore hip biomechanics in a wider range of patients.


COXA VARA High Offset Stem KLA collared neck option offers an increased offset and varus neck angle for femoral restoration and proper soft-tissue tensioning of varus angles patients.


Short Neck options, designed for smaller patient anatomy, reduce leg length by 5 mm compared to standard neck.


Additionally the 135° Short Neck reduces offset by 5mm allowing the restoration of hip biomechanics in a wider range of patients.

Collared stems are available in all neck options to assist controlling subsidence and add rotational stability in patients with osteopenic bone.
