Zusammenfassung
Die posttraumatische tibio-fibulare Synostose (PTFS) ist eine seltene Komplikation nach Schienbein- und Knöchelfrakturen. Distal werden Synostosen am häufigsten beobachtet, sie kommen aber auch im mittleren und poximalen Drittel vor. Die proximal gelegenen Synostosen sind auf Nativröntgenbildern schwierig, im CT jedoch leicht zu entdecken. Fünfzehn Patienten (5 Frauen, 10 Männer) mit PTFS wurden nachuntersucht. Ihr Alter beim initialen Trauma lag zwischen 18 und 57 Jahren, im Mittel bei 35,9 Jahren. Der Nachuntersuchungszeitpunkt lag zwischen 2 und 22 Jahren, im Mittel 5,2 Jahre nach Trauma. Die meisten Patienten beklagten Schmerzen und/oder Bewegungseinschränkung im oberen Sprunggelenk. Die milde Beschwerdesymptomatik und leichte bis moderate Bewegungseinschränkung rechtfertigten eine Resektion der Knochenbrücke nicht. Arthrosezeichen wurden auf den aktuellen Röntgenbildern nicht gefunden. Schlussfolgerung: Auch symptomatische Patienten mit PTFS sollten konservativ behandelt werden.
Abstract
Background: Post-traumatic tibio-fibular synostosis is a rare complication of tibial and ankle fractures. Distal tibio-fibular synostosis is the most common, but midshaft, or proximal tibio-fibular synostosis are also found. Proximal tibio-fibular synostosis is difficult to detect on routine X-rays, but is clearly discernible on computed tomography scans. Methods: Fifteen patients (5 females and 10 males) suffering from post-traumatic tibio-fibular synostosis were followed up. Age at time of initial trauma ranged from 18 to 57 years (mean, 35.9 years). Follow-up time from initial trauma ranged from 2 to 22 years (mean, 5.2 years). Results: Most of the patients suffered from pain and/or limitation of ankle movement. The mild symptoms and mild-to-moderate decrease in ankle motion did not justify surgical excision of the bony bridge. No signs of osteoarthrosis were detected in any of the recent radiographs. Conclusion: Even symptomatic patients should be treated by conservative methods.
