Isolated talocalcaneal interposition fusion: a prospective follow-up study.
This is a prospective clinical and radiological study of the treatment of talocalcaneal deformity or degeneration by a modified technique of isolated talocalcaneal fusion. Thirty-six patients were evaluated with clinical examination, plain dorsoplantar and oblique radiographs, and computed tomography scanning or magnetic resonance imaging in a follow-up of 32.5 months (range, 20-62 months). Indications for arthrodesis were posterior tibial tendon rupture with secondary osteoarthritis (12 cases) and secondary posttraumatic osteoarthritis (24 cases). On a visual analog pain scale, the patients graded their pain at 4.4 before surgery and at 1.1 after surgery. The subjective results were 33% complete satisfaction, 28% satisfaction with minor reservation, 31% satisfaction with major reservation, and 9% dissatisfaction. The overall objective results were excellent in 47%, good in 31%, fair in 17%, and poor in 6% of cases. A further advantage of this type of talocalcaneal fusion is a large remaining range of motion in the neighboring joints, at the ankle (in 76% the same or better ROM than before surgery), and at Chopart's joint (in 69% the same or better ROM than before surgery). The fusion rate was high (95%).
