[Results of the surgical treatment of bridge callus through silastic membrane interposition]

A report on 5 cases with successful treatment of a posttraumatic synostosis of radius and ulna by resection and interposition of a silastic-membrane is presented. This membrane has to ensheath one of the forearm bones for at least half of its circumference and it is fixed partially with Dexon sutures. During operation it is necessary to confirm this fixation of the membrane, which must be unchanged after rotation of the forearm. The range of movement reached 4 years after operation was about 120 degrees (100-130 degrees) on an average. A better result can only be expected by an osteotomy of the radius and correction of its position.
