1. A measuring adapter for a measuring instrument for use in connection with hip prosthesis surgery, wherein the measuring adapter comprises:
a measuring head comprising a front end, a rear end and an upper surface; the measuring head being divided into at least two separate sections; and
a connector; the connector being hollow and slotted at one end in an axial direction of the measuring head into a number of legs, the number of legs corresponding to the number of the at least two separate sections of the measuring head; wherein each leg of the connector is connected to one of the at least two separate sections of the measuring head on the rear end of the measuring head;
wherein at least a part of the upper surface of the measuring head is adapted to be moved from a relaxed state to an expanded state,
wherein in the expanded state the at least a part of upper surface of the measuring head defines an expanded-state perimeter and the at least a part of the upper surface of the measuring head adopts the shape of
a spherical cap; or
a convex shape comprising at least a spherical segment, and
wherein, in the relaxed state, the at least a part of the upper surface of the measuring head is within the expanded-state perimeter.
