title: A method for evaluating carpal alignment on lateral radiographs.
abstract: An alternate method of diagnosing carpal instability has been presented. The apparatus is easy to construct and is inexpensive. If the apparatus is used properly, it will enable the technician to obtain consistent and comparable radiograph projections. The use of a clear plastic rule with concentric circles is optional but may assist in a more accurate centering of the capitate and lunate circles.
