Summary
A case of an anomalous ossicle in a lumbar facet joint is reported and the operative findings presented. The nature of the anomaly is not fully understood but is thought to be the result of non-fusion between a normal appearing ossification center and the adjacent articular process. The patient's symptoms — severe chronic low back pain — subsided completely after surgery. It is concluded that the presence of such ossicles in facet joints in some cases may lead to severe symptoms and that surgical treatment in such cases should be considered.
Zusammenfassung
Es wird über einen Fall mit einem anomalen Ossikel eines lumbalen Wirbelgelenkes berichtet und der operative Befund präsentiert. Die Natur dieser Anomalie ist nicht geklärt, aber es wird vermutet, daß dies das Resultat einer nicht stattgefundenen Fusion zwischen einem normalen Ossifikationszentrum und dem benachbarten Gelenkfortsatz darstellt. Die Symptome, starke chronische Rückenschmerzen, verschwanden nach der Operation vollständig. Daraus wird geschlossen, daß ein solches Ossikel in einem Fazettengelenk in manchen Fällen eine schwere Symptomatik hervorrufen kann und daß man dann eine operative Behandlung ins Auge fassen sollte.
