RESUMO
Tibiotalocalcaneal arthrodesis is still considered the reference standard therapy for salvage of severe osteoarthritic deformities of the ankle and hindfoot. Because of the unique anatomy and biomechanics of the ankle, even minor injuries can progress to end-stage osteoarthritis over time. This can be debilitating to patients' general health and physiologic ambulation. Arthrodesis aims to correct the misalignment and should comply with Glissan's principles (i.e., maintenance of permanent stability and sound compression between the fused elements). Several different surgical techniques have been described in the international medical literature. Intramedullary nails can create and maintain a stable condition but lack the necessary compression. Screw fixation can generate compression but might not yield enough stability until sound union has been achieved. In the present study, we report the early results of an innovative posterolateral polyaxial angle-stable plate that combines the features that address all the principles of arthrodesis in 1 device.
