[Intramedullary nailing in tibiotalocalcaneal arthrodesis]

Tibiotalcalcaneal arthrodesis is still the treatment of choice for disabling arthrosis of the upper and lower ankle joint, although replacement of the upper ankle joint is widely accepted. Numerous techniques have been described, with increasing use of internal fixation and compression. In 20 patients tibiotalocalcaneal arthrodesis was performed using a retrograde femur nail inserted through the heel, whereas in 20 patients combined arthrodesis of the upper and lower ankle joint was performed using a distal tibia nail through an anterograde approach. Patients were evaluated in a standardized examination using criteria of SF 36 focussing on approach, osseous consolidation, and quality of life.Both techniques demonstrated good results: bony consolidation was achieved after follow-up time of 19 months in 85% of the anterograde group and 95% of the retrograde group. In 78% pain was reduced effectively using the intramedullary nail arthrodesis and quality of life improved drastically. In four cases pseudarthrosis occurred, two implant failures were reported, and there were two infections. Using the anterograde as well as the plantar approach, tibiotalocalcaneal intramedullary nail arthrodesis is an appropriate technique. In this study both groups demonstrated good results regarding bony consolidation, reduction of pain, and improved quality of life. Advantage of the retrograde technique is the noninvasiveness of the proximal tibia. Heel pain or plantar infections were not observed. We see limits of the presented technique in severe malalignment and septic history of the patient.
