Hindfoot deformity is not a rare condition in rheumatoid arthritis. Severe deformity causes pain which is a result of abnormal weighing, so it is necessary to correct the deformity in such cases. But sufficient correction cannot be obtained with the conventional method, triple arthrodesis. Therefore, we have developed a new surgical technique for correcting severe hindfoot deformity in rheumatoid arthritis. It consists of the following procedures: (1) removal of the navicular bone; (2) resection of the articular cartilages; (3) reduction of the deformity; (4) return of the navicular bone; and (5) fixation with k-wires.
The improvements of the calcaneal pitch of the feet treated with conventional triple arthrodesis and with the new technique were -1°±3° and + 6°+4°, respectively. The good correction with the new technique was certified not only by plain X-ray pictures but also by frontal tomograms and footprints.
