Aseptic Pseudoarthrosis of the Humeral Diaphysis. Epidemiological Features—Therapeutic Assessment

Objective: The aim of this work was to assess the epidemiological factors of the pseudoarthroses of diaphyseal humeral fractures in order to prevent them and also to assess the results of their treatment by screwed plate associated with an auto-graft. Material and method: This was a retrospective series of 36 aseptic pseudoarthroses of the humeral diaphysis treated by screwed plate, associated or not with a bone autograft between January 1997 and December 2016 at the Treichville University Hospital. The criteria of inclusion refer to the existence of an aseptic pseudoarthrosis of the humeral diaphysis treated by screwed plate. The approach was antero-external. Two thirds of pseudoarthroses were between the middle 1/3. 23 atrophic pseudoarthroses (65%) and 13 hypertrophic pseudoarthroses. Functional results were assessed using the Steward and Hundley criteria. Results: Mortality was zero, and postoperative complications were dominated by 4 hematomas and 2 transient iatrogenic paresthesias of the radial nerve. The sequelae were minor and the consolidation was acquired in 97.25% of patients. Conclusion: The treatment of aseptic pseudoarthroses of the humerus by screwed plate associated with an auto-graft is a reliable technique, inexpensive with a satisfactory functional outcome.
