A modular intervertebral implant or a modular intervertebral disk prosthesis has a middle piece or central section equipped with elements for detachable fixation to one or two apposition plates designed to rest against the base plate or cover plate of an intervertebral body. The DMT system provides a robust and fast protocol for completing this seamless rate adaptation. To reduce interference, the wireless interface may provide services to a first wireless communication device using a pilot signal emitted from the base station at a reduced power level. The inlet channels twist together from the dovetail, through the platform, and into the airfoil behind the leading edge in transverse adjacent alignment across the sidewalls.
