Charnley clamps

Charnley clamps
an apparatus used to encourage arthrodesis between the ends of two bones on either side of a joint. Parallel pins driven through the bone ends are connected on each side of the joint by bolts bearing wing nuts; tightening of the screw arrangements forces the surfaces of the bones together. When the two bones have joined, by growth and reshaping, the clamps can be removed.
Sir J. Charnley (1911-82), British orthopaedic surgeon
