[Arthrodesis of the foot and ankle].

Performing an arthrodesis is a common technique to treat multiple different foot deformities. Primary osteoarthritis and post-traumatic conditions are the most frequent indications. Various complications and reasons for failure can occur like non-union, nerve damage, wound healing disorders or adjacent joint degeneration. The highest fusion rates can be achieved by compression of the joint space using modern osteosynthesis material. Postoperative care needs to be adapted to intraoperative stability, quantity and location of the fused joints and the compliance of the patient. Nerve damage and wound healing problems can be avoided by subtle soft tissue preparation and intraoperative hemostasis. Degeneration of the adjacent joints is inherent to method but can be minimized by selective arthrodesis of only the affected joints.
