[Ankle arthrodesis with an posterolateral approach using a polyaxial angle stable Talarlock® plate].

Safe arthrodesis of the ankle as well as load carrying capacity free of pain.Painful arthritis of the ankle joint occurring idiopathic or posttraumatic, resulting from rheumatoid arthritis or neuromuscular diseases. Extensive bony defects in varus or valgus ankle deformities and after failed prosthesis. Complex hindfoot deformities in neurological disease, paralysis and instabilities. Joint destruction after infection.Active osteitis, extensive skin ulcers in the approach area, periphery artery occlusive disease.Posterolateral skin incision. Sparing cartilage resection. Penetrating sclerosis zones. Reorientating anatomic positioning of the talus thereby correcting axis deformities. Talarlock(®) plate positioning and tibiotalar arthrodesis.Full weight bearing in an arthodesis boot for 6 weeks. After bone grafting partial weight bearing (20 kg) in an arthrodesis boot for 8 weeks. Full weight bearing after 10weeks.Ten patients were operated on using this procedure. The follow-up time was 1 year. There were no complications requiring further surgical procedures. Ankle fusion and a good clinical outcome could be achieved in all cases.
