Bone plate () with a lower surface (), an upper surface (), a maximum thickness measured between the lower and upper surfaces a left lateral surface (), a right lateral surface (), a longitudinal axis () and a plurality of plate holes () miming from the lower surface to the upper surface, the bone plate further having a slot () in the lower surface extending from the left lateral surface to the right lateral surface having a width measured in a plane parallel to the longitudinal axis and a central plane () between the lateral surfaces, wherein (i) the hollow space defined by the slot extends in the form of a straight cylinder from the left lateral surface to the right lateral surface and (ii) the slot comprises an undercut feature () limiting the opening of the slot when the bone plate is bent longitudinally in a direction aimed at widening the slot.

Biphasic bone plate

The bone plate () has a lower surface (), an upper surface (), a thickness T measured between the lower and upper surfaces (), a longitudinal axis () and a plurality of plate holes () running from the lower surface () to the upper surface (). The bone plate () further has a slot () extending from the lower surface () towards the upper surface () and having a width W measured at the lower surface () and parallel to the longitudinal axis (). The slot () extends to a maximum distance D measured from the lower surface () towards the upper surface () of 0.4-0.9 times the thickness T of the bone plate (). The slot () has a width measured parallel to the longitudinal axis () which at its maximum extension E is at least 0.8 mm, preferably of at least 3 mm. The slot () allows the plate () to bend longitudinally&#x2014;additionally to the intrinsic bendability of the unslotted plate ()&#x2014;at most to the amount of 20&#xb0;, preferably at most to the amount of 10&#xb0;. Due to the bi-phasic properties of the bone plate () optimal bending properties and adaptability to anatomical surfaces are achieved.
