Ray amputation of the long or ring fingers may be required for trauma, infection, tumor, or congenital conditions. This may leave a gap between adjacent fingers that impairs overall hand function and through which small objects may drop. The patient may have significant difficulty handling small objects, such as coins, keys, nails, screws, nuts, or bolts. One method of managing such a problem is to transpose the index finger ray to the long finger stump or the small finger ray to the ring finger stump.
