Internal Fixation Compression Arthrodesis of the Ankle

Talocrural arthrodesis with absorbable screws

“…In our technique the absorbable screws were inserted obliquely from the tibia and fibula to the talus directing the stress to the uniting joint, and full weight bearing was allowed immediately. The high union rate (11 out of 12) achieved in our study was favorable when compared with the results achieved earlier (Marcus et al 1983, Breitfuss et al 1989, Dennis et al 1990, Holt et al 1991, Mann et al 1991. The only nonunion in our…”

“…Metallic screws have been used with various techniques in the fixation of an ankle arthrodesis (Marcus et al 1983, Breitfuss et al 1989, Dennis et al 1990, Holt et al 1991, Mann et al 1991. The stiffness of metallic screws may lead to nonunion if the screws are inserted in a way that prevents stress transfer to the uniting bone surfaces.…”

Die Arthrodese des oberen Sprunggelenks über den sog. transfibularen Zugang

“…Nachteilig sind die aufwendige Pflege der Eintrittsstellen der Fixateurschrauben, die Behinderung der Mobilisation durch das Gestänge sowie die häufigen Infekte und Lockerungen der Schanz-Schrauben (18-80%, zitiert in [4]). In neueren Arbeiten ergibt die Schraubenfixation eine gute Heilungsrate und eine geringe Anzahl von Komplikationen [9,14,[20][21][22]. Neue arthroskopisch assistierte Techniken können mit noch weniger Komplikationen und einer guten Konsolidierungsrate gefallen [27], bedingen aber die Auswahl von Patienten ohne Fehlstellung.…”

“…The disadvantage is the time-consuming care of the entry points of the fixation screws, the interference of the rods with the gait, as well as the frequent infections and loosening of the Schanz screws (18-80%, cited by [4]). More recent studies using screw fixation reported an encouraging rate of consolidation as well as a low number of complications [9,14,[20][21][22]. With arthroscopically assisted techniques a further reduction in complications and improvement of the rate of consolidation can be expected [27].…”

Die „Beckenkammspan-Interpositionsarthrodese“ des oberen Sprunggelenks

“…Various techniques have been described [1,2,7,8,10,12,13,15,19,20]. Biomechanical investigations have shown a greater stability of internal fixation with screws than with external fixation [6,14,18].…”
