Abstract

This level IV case series study prospectively evaluated patients with atrophic proximal humerus nonunions stabilised with a locking 90° blade plate. All patients were women with an average age of 69 years (range 56–78). Time from trauma to nonunion treatment averaged 23 months. Five patients had had previous surgical treatments. Two patients had a history of infection and one patient with active infection was reconstructed in two stages. Follow-up averaged 22 months (range 18–36); union was achieved in all seven cases after an average of 5.85 months. The DASH score at the last follow-up averaged 25 points and Constant score averaged 72.7 points. No patient required additional procedures. At the last follow-up all patients were free of infection, and there were no cases of avascular necrosis. The results with locked 90° blade plates in atrophic nonunions of the proximal humerus in adults were favourable in this series.

Résumé

L'objectif de cette étude est de réaliser une évaluation prospective des pseudarthroses arthrophiques de l'extrémité supérieure de l'humérus stabilisées par une lame plaque verrouillée à 90°. tous les patients étaient des sujets féminins avec un âge moyen de 69 ans (56 à 78). La période entre le traumatisme et la pseudarthrose était en moyenne de 23 mois. 5 patients n'avaient pas eu de traitement avant la survenue de la pseudarthrose. Deux patients avaient une histoire d'infection et 1 patient une infection évolutive avec une reconstruction en deux temps. le suivi moyen a été de 22 mois (18 à 36). Une consolidation a été obtenue dans tous les cas après 5,85 mois en moyenne. Le score DASH au dernier suivi était de 25 points et le score de Constant de 72,7 points. Aucun patient n'a nécessité un geste chirurgical additionnel. Au dernier suivi aucun patient ne présentait d'infections, il n'y avait pas de nécrose vasculaire. le résultat du traitement d'une pseudarthrose arthrophique de l'extrémité proximale de l'humérus avec une lame plaque de 90° chez l'adulte est extrêmement favorable.
