Speed-brakes are not always attached to the fuselage - they can be found pretty much anywhere. On the STS they're in the tail-fin (split-rudder), on the Avro Vulcan they extend vertically up through the top of the wing. The YF-23 uses the flaps and ailerons in opposition. and the A-10 has split ailerons - the top half deflects up and the lower half down.
