Nonunion of fractures of forearm bone occurs frequently. These patients usually suffer from pain and functional disturbance of the hand and forearm. With the introduction of compression plate for the treatment of nonunion at the Campbell Clinic in 1959, a modification of the Nicoll graft was advised. The authors analysed 23 cases of the nonunion of forearm bone, in which military injured patients were admitted and treated by bone graft with internal fixation using various devices in Department of Orthopaedic Surgery of Korea Veterans Hospital from Sep. 1983 to Aug. 1988.
