An assembly for reducing a fracture between an epiphysis and a diaphysis of a bone has a bone plate having a fan-shaped outer end formed with a plurality of outer holes and a bar-shaped inner end extending along a longitudinal axis from the outer end and formed with a plurality of inner holes. The plate further is formed on the bar-shaped inner end with a longitudinally extending through going guide slot and between the guide slot and the outer holes with an aperture. A slide has a longitudinally extending leg with an inner end formed with a guide formation engaged into and longitudinally slidable along the guide slot and a crosspiece overlying the aperture and engaging the bone plate to both transverse sides of the aperture. The crosspiece is formed with a transversely elongated slide slot, and a slide screw engaged through the slide.

Radius plate assembly

A bone plate for a fracture between an epiphysis and a diaphysis has an outer part unitarily formed with a fan-shaped outer end having a plurality of outer holes and an inner end extending from the outer end. A bar-shaped inner part has an outer end juxtaposed with the inner end of the outer part and formed inward of its outer end with a plurality of inner holes. A pivot is provided between the inner end of the outer part and the outer end of the inner part. Formations juxtaposed with the pivot on the inner end of the outer part and on the outer end of the inner part are lockable together in each of a plurality of angularly offset fixed positions of the inner and outer parts. When the formations are pressed together the inner and outer parts are locked angularly relative to each other.
