Small joint fusion of the hand--a technique using Coughlin cup and cone reamers

We describe a method of cup and cone arthrodesis using Coughlin concave and convex reamers, which we have used in a series of 22 hand joints in 19 patients. These reamers, originally designed for use in the foot, can be used in the hand to give very accurate preparation of bone surfaces. This results in maximum bone contact and the ability to fuse the joint in any desired position. The procedure is simple, rapid and forgiving. Union was achieved in all 22 cases, usually within 3 months.
