Arthrodesen am sprunggelenk und rückfuß

Abstract

Indications for arthrodesis of the ankle include post-traumatic sequelae, rheumatoid arthritis, joint infection, diabetic osteoarthropathy, failed arthroplasty, idiopathic arthritis and neuromuscular misalignment. Distinction is made between arthrodesis of the upper ankle (tibiotalar), the lower ankle (talocalcaneal) and the entire hindfoot (tibiotalocalcaneal). Patient history and clinical examination form the basis of diagnosis and may be complemented by imaging techniques. The main principle of ankle arthrodesis is prompt establishment of the indication. Preparing the joint surface can be performed either by conventional open procedure or arthroscopically, whereby the former is considered the standard procedure. Osteosynthesis techniques include external fixation as well as screw, plate and nail techniques. Correct alignment of the hindfoot is essential for a functional outcome. © Springer-Verlag 2010.
