Zusammenfassung

Die operative und konservative Behandlung der akuten AC-Gelenksprengung wurden anhand einer retrospektiven Langzeitstudie verglichen. 46 Patienten wurden konservativ behandelt, bei 51 Patienten wurde eine korakoklavikuläre und akromioklavikuläre Bandnaht mit Stabilisierung des AC-Gelenks durch eine resorbierbare PDS-Cerclage durchgeführt. Nach durchschnittlich 6,3±2,5 Jahren wurden 38 konservativ behandelte und 42 operierte Patienten klinisch und radiologisch nachuntersucht. In beiden Gruppen wurden anhand des UCLA- und des Constant-Murley-Scores sowie hinsichtlich Schmerz, Funktion und Kraft gleichwertige Ergebnisse erzielt.

Die Inzidenz an posttraumatischen AC-Gelenkarthrosen war in beiden Gruppen vergleichbar, wobei die Arthrosen vorwiegend bei verbleibender Subluxation des AC-Gelenks auftraten. Die nach konservativer Behandlung zu erwartende persistierende Fehlstellung führte weder zu Schmerzen noch zu einem Kraftverlust, sodass die überwiegende Mehrheit der Patienten mit akuter, kompletter AC-Gelenksprengung erfolgreich konservativ behandelt werden kann.

Abstract

42 patients with complete acromioclavicular dislocation treated operatively and 38 patients managed non-operatively were examined retrospectively with a mean follow-up of 6.3±2.5 years. The dislocations in both groups included type III and type V injuries according to the Rockwood-classification. The operative technique was suturing of the torn ligaments and stabilization of the acromioclavicular joint using resorbable coracoclavicular PDS-banding. In non-operative treatment, early physiotherapy accepting the deformity was performed in most of the patients. The clinical results using the UCLA-and the Constant-Murley score as well as evaluation of pain, function and strength were similar in both groups. Those patients suffering from a more severe dislocation type Rockwood V who were treated non-operatively had as good results as those patients with grade III dislocation.

Posttraumatic osteoarthritis developed mainly in those patients whose acromioclavicular joint healed in partial dislocation. Non-operative treatment was equal even in less severe dislocations in the subgroup of type Rockwood V injuries. The persisting deformity which must be expected in non-operative treatment did not affect the patient's outcome regarding pain, function and strength of the shoulder.
