1. A bone plate for reducing a fracture between an epiphysis and a diaphysis of a bone, the plate comprising: an outer part unitarily formed with a fan-shaped outer end formed with a plurality of outer holes and an inner end extending along a longitudinal axis from the outer end, the outer part being adapted to be screwed through the outer holes to the epiphysis; a bar-shaped inner part having an outer end juxtaposed with the inner end of the outer part and a plurality of inner holes formed inwardly of the outer end thereof, the inner part being adapted to be screwed through the inner holes to the diaphysis, the outer end of the inner part having a throughgoing slot positioned over an extension of the inner end of the outer part, the throughgoing slot having a longest dimension in a direction transverse to the longitudinal axis, the extension projecting under the outer end of the inner part and including a circular screw seat on an end thereof; a pivot between the inner end of the outer part and the outer end of the inner part and defining a pivot axis; formations juxtaposed with the pivot and lockable together in each of a plurality of angularly offset fixed positions of the inner and outer parts; means for pressing the formations together and thereby locking the inner and outer parts at various angles relative to each other in each of the positions; and a screw having a shaft seated in the screw seat and a head engaging the outer end of the inner part, the screw shaft and the screw seat being dimensioned for engagement with each other around entire circumferences thereof; wherein the throughgoing slot is sized to permit engagement of the screw with the outer part through the throughgoing slot during relative pivoting of the outer and inner parts.
