Abstract
Between 1974 and 1999, we treated operatively 28 patients with a symptomatic mid-shaft clavicular non-union using AO osteosynthesis, including bone grafting. Nine patients had a wave-plate osteosynthesis and 19 a standard AO/ASIF osteosynthesis. The mean follow-up was 10 (2–25) years. All but one non-union showed full bony consolidation. Pre-operatively, brachialgia was present in 12 patients. Of these patients, six were treated using standard osteosynthesis technique and six by wave-plate osteosynthesis. Post-operatively, patients treated by wave-plate osteosynthesis had no brachialgia and also had a higher Constant score than those patients treated using standard AO/ASIF techniques.
Résumé
Entre 1974 et 1999, nous avons opérés 28 malades avec une pseudarthrose symptomatique de la clavicule en utilisant une ostéosynthèse AO avec greffe osseuse. Neuf malades avaient une ostéosynthèse par plaque incurvée et 19 une ostéosynthèse AO/ASIF standard. Le suivi moyen était de 10 (2–25) années. Toute les pseudarthroses, sauf une, ont consolidé. Avant l'opération 12 malades présentaient des brachialgies. De ces malades, six ont été traités par ostéosynthèse standard et six par ostéosynthèse par plaque incurvée. Les malades traités par plaque incurvée n'avaient plus, après l'opération, de brachialgie et avaient un plus haut score de Constant que ceux traités par la technique AO/ASIF standard.
