Zusammenfassung
Einleitung: Läsionen des Nervus femoralis oder Nervus ischiadicus sind eine typische Komplikation
nach Totalendoprothesenimplantation des Hüftgelenkes. Verzö gerte Läsionen des Nervus
ischiadicus bzw. des Nervus femoralis stellen hingegen eine Rarität dar.
Falldarstellung und Verlauf: Wir berichten über eine verzögerte Funktionsstörung des Nervus ischiadicus nach Totalendoprothesenimplantation
des Hüftgelenkes mit Rekonstruktion des Acetabulums mit Stützringosteosynthese. Nach
elektrophysiologischer Untersuchung erfolgte die Revision des Nervus ischiadicus.
Intraoperativ zeigte sich, dass der Nerv am Hinterrand des Stützringes eingeengt und
dorsal durch eine Narbe bedrängt war. Ventral lag der Nerv unmittelbar dem Rand des
Stützringes an. Nach Revision des Nerven und lösen von Narben wurde ein gestielter
Fettlappen zwischen Stützring und Nervus ischiadicus interponiert. Die Patientin war
unmittelbar nach Operation schmerzfrei, litt jedoch noch unter Empfindungsstörungen
im Bereich der rechten Großzehe.
Schlussfolgerung: Bei der Verwendung von Stützringen muss auf den korrekten Sitz des Implantates geachtet
werden, ein Überragen der Hinterkante kann bei engen anatomischen Lagebeziehungen
zu einer Irritation des Nervus ischiadicus führen.
Abstract
Aim: Lesions of the sciatic or femoral nerve after THR are typical complications. Delayed
neuropathies of the sciatic or femoral nerve are rare conditions.
Case report: We report the case of a delayed neuropathy of the sciatic nerve after THR with reconstruction
of the acetabulum with an acetabular reinforcement ring. After electrophysiologic
evaluation we performed a revision of the sciatic nerve. Intraoperatively we found
an impingement of the sciatic nerve between the dorsal aspect of the acetabular reinforcement
ring and scar tissue. After revision of the nerve, resection of the scar tissue and
interposition of a fat pad the patient was out of any complaints but reported some
sensory deficits of the first toe.
Conclusion: Using acetabular reinforcement rings for reconstruction of acetabular defects care
has to be taken of the correct position. In anatomically cramped positions a protruding
of the dorsal edge of the ring may cause a lesion of the sciatic nerve.
