Zusammenfassung
In den letzten Jahren wurden vermehrt arthroskopische Techniken bei der Versorgung von Glenoidfrakturen beschrieben und deren funktionelle und radiologische Ergebnisse veröffentlicht. Spricht man von Glenoidfrakturen, müssen grundsätzlich knöcherne Bankart- von Impressionsfrakturen unterschieden werden. Zur Versorgung knöcherner Bankart-Frakturen können Fadenanker verwendet werden, mit denen Fragment und Kapsel-Labrum-Komplex refixiert werden. Bei größeren Fragmenten, die 20% des Glenoidlängsdurchmessers überschreiten, ist die arthroskopische Schraubenosteosynthese Technik der Wahl. Durch Wiederherstellung der anatomischen Verhältnisse am Glenohumeralgelenk können Komplikationen wie Schulterinstabilität, persisitierende Schmerzen, Gelenkinkongruenz und das Auftreten einer frühzeitigen posttraumatischen Omarthrose verhindert werden. Die radiologischen und funktionellen Ergebnisse nach arthroskopischer Versorgung von Glenoidfrakturen sind mit niedriger Komplikationsrate und hoher Patientenzufriedenheit überzeugend.
Abstract
In recent years an increasing number of arthroscopic techniques for treatment of glenoid fractures have been described and functional and radiological results have been reported. Regarding glenoid fractures, two types of pathologies have to be distinguished: bony Bankart lesions and impression fractures. For the arthroscopic treatment of bony Bankart lesions anchors can be used to fix the fragment and labrum capsule complex. In cases with a fragment sizes exceeding 20% of the glenoid length, arthroscopic screw fixation is the technique of choice. With the aim to restore gleno-humeral joint anatomy, complications such as shoulder instability, persistent pain, joint incongruity and development of early posttraumatic osteoarthritis can successfully be prevented. The radiological and functional results after arthroscopic treatment of glenoid fractures are convincing and associated with a low rate of complications and high patient satisfaction.
