Hindfoot Deformity Corrected With Double Versus Triple Arthrodesis: Radiographic Comparison.

Abstract
Hindfoot fusion is capable of correcting hindfoot deformities. Typically, this has been done through triple arthrodesis. Recently, there has been some discussion of a double arthrodesis, sparing the calcaneocuboid joint. We compared the radiographic corrective ability of these 2 fusion techniques. A retrospective radiographic review was performed of 20 consecutive triple arthrodeses (triple) and 20 consecutive talonavicular and subtalar arthrodesis with calcaneocuboid preservation (double). Additional midfoot arthrodesis or osteotomy was performed as needed in each group. The preoperative measurements were compared to those from standing weightbearing films after fusion postoperatively. The angular measurements included the anteroposterior and lateral talar–first metatarsal line (Meary's and Simmons) and the anteroposterior and lateral talocalcaneal angle. Both groups demonstrated a statistically significant reduction in deformity and a return to more normal radiographic findings after arthrodesis (p < .05). The 2 groups did not differ statistically in preoperative deformity or correction obtained (p > .05). Traditionally, triple arthrodesis has been advocated for significant hindfoot deformity that is irreducible. Recent studies have questioned the need for inclusion of the calcaneocuboid joint in the arthrodesis, in particular, in a pronated, valgus-type foot. In addition, others have advocated a strictly medial approach to hindfoot fusion, necessarily avoiding the calcaneocuboid joint. Our findings agree with the assertion that hindfoot deformity can be adequately and reliably corrected through hindfoot arthrodesis whether or not the calcaneocuboid joint is included.
