We performed ninety-six internal-fixation procedures for @entity174 or non-union of the humeral shaft in eighty-four @entity1 , with a mean follow-up of 32.6 months (range, three months to fourteen years). The primary indications for operative intervention included humeral shaft @entity174 in a @entity1 with @entity1230 , non-union, inadequate reduction of a humeral shaft @entity174 by closed methods, pathological humeral-shaft @entity174 , and progressive @entity4542 . Methods of internal fixation included compression plates and screws and intramedullary K  ntscher nails or Rush rods. The use of an AO/ASIF compression plate or interfragmentary lag screws with an AO/ASIF neutralization plate in twenty-seven multiply-injured @entity1 resulted in a union rate of 100 per cent and generally good motion of the shoulder and elbow. Five multiply-injured @entity1 also obtained good results through fixation by a modified Hackethal technique using two Rush rods. The use of intramedullary K  ntscher nails resulted in a rate of union of 91 per cent in eleven multiply injured @entity1 . Ten @entity1 with non-union of a humeral shaft @entity174 had an 80 per cent rate of union with the use of an AO/ASIF compression plate. The use of a K  ntscher nail in eleven @entity1 with non-union resulted in a rate of union of only 73 per cent and frequently caused @entity5818 . @entity174 of the humeral shaft that had had an inadequate reduction by closed means or were associated with progressive @entity4542 were best managed by a compression plate or the modified Hackethal technique.(ABSTRACT TRUNCATED AT 250 WORDS)
