We report 58 cases of humeral shaft non union following 28 times an orthopaedic treatment where persisted a space between the two fragments and 30 times an osteosynthesis but only 6 where satisfying. The sery contains 2 infected non union, dried in several months and 3 pseudarthrosis we did not operate because they were not inconvenienced. Among the 53 aseptic pseudoarthrosis the union has been to obtained after one operation for 42, two operations for 6 and three operations for 5. We analyse the consecutive mistakes having brought to the failures. We confirm that only an osteosynthesis not sufficient and that an associate graft is necessary. It could be an osteoperiosteum decortication, a spongious graft or a tibial graft (this last one is more safe but reserved to the iterative cases of the one with a big defect). The long evolution (more than a year for half at the cases) explains the fragment repercussions on shoulder or elbow.
