Zusammenfassung
Hintergrund
Die knöcherne Läsion des Glenoids nach vorderer Schulterluxation ist eine häufige Begleitpathologie. Eine Inzidenz von 41 % nach Erstluxation bis 90 % bei rezidivierender Luxation wurde beschrieben. Untersuchungen der Ursache unzufriedenstellender Ergebnisse nach Bankart-Operationen mit alleiniger Weichteilstabilisierung haben gezeigt, dass in den meisten Fällen eine relevante knöcherne Läsion außer Acht gelassen wurde.
Diagnostik
Das konventionelle Röntgen hat weiterhin seinen diagnostischen Stellenwert im Rahmen der Behandlung von Schulterluxationen. Gerade die Beurteilung der knöchernen Integrität des Glenoids kann jedoch selbst auf Zielaufnahmen schwierig sein. Daher ist die Durchführung einer Computertomographie (CT) auch schon nach Erstluxation empfehlenswert.
Therapie
Wird eine knöcherne Läsion des Glenoids rechtzeitig erkannt, so ist je nach Fragmentgröße dessen Refixation durch Fadenanker oder Schraubenosteosynthese indiziert, wodurch eine anatomische Rekonstruktion und damit ein stabiles Schultergelenk erreicht werden kann. Bei chronischer Defektsituation mit teilweise resorbiertem Fragment ist eine knöcherne Augmentation des Glenoids entweder durch Korakoidtransfer oder Beckenkammspan erforderlich, um eine andauernde Stabilität zu erreichen.
Schlussfolgerung
Nach Luxation des Schultergelenks muss vor weiterer Therapieplanung die Beschaffenheit des Glenoids exakt beurteilt werden. Hierzu ist ein CT auch schon nach Erstluxation empfehlenswert. So kann ggf. frühzeitig eine Osteosynthese durchgeführt und eine spätere autologe Knochentransplantation zur Rekonstruktion eines chronischen Defekts durch Korakoidtransfer oder Beckenkammspan vermieden werden.
Abstract
Background
Osseous lesions of the glenoid cavity after anterior dislocation of the shoulder joint are a common accompanying pathology. The incidence ranges from 41 % after first time dislocations to 90 % with recurrent dislocations. Investigations searching for possible reasons for unsatisfactory results of Bankart operations with soft tissue stabilization alone have shown that in most cases such osseous lesions had not been taken into account when planning the individual surgical procedures.
Diagnosis
Conventional x-ray imaging remains the main diagnostic tool for treatment of shoulder dislocations; however, assessment of the osseous integrity of the glenoid cavity can be problematic even with additional images. Therefore, a computed tomography (CT) scan of the shoulder joint is recommended even after first time dislocations.
Therapy
If an osseous lesion of the glenoid cavity is diagnosed in time, refixation either by suture anchors or screws is indicated depending on the fragment size. This allows anatomical reconstruction of the glenoid cavity and most likely results in a stable shoulder joint. With chronic defects of the glenoid cavity and partially resorbed osseous fragments, bony augmentation either by coracoid transfer or a transplant from the iliac crest is required to achieve permanent stability.
Conclusion
Exact assessment of the osseous condition of the glenoid cavity is crucial for planning further therapeutic steps. In this respect a CT scan is recommended even after first time dislocation. Thus, early refixation of such fragments can avoid the possible necessity of autologous bone augmentation either by coracoid transfer or iliac crest graft.
