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]
