[Expert consensus on the clinical diagnosis and management of Talocalcaneal coalition (2025 Edition)].

Talocalcaneal coalition is one of the most common tarsal coalitions caused by bone, cartilage or fibrous connection between the talus and calcaneus due to congenital factors. Many patients have no obvious symptoms, and the onset is mostly manifested by bony protrusions of the medial malleolus, pain when walking, and impaired mobility of the subtalar joint. Missed diagnosis and inappropriate treatment often occurred for its low incidence and insidious onset. Therefore, the Foot and Ankle Group of Orthopedics Branch of Chinese Medical Association, Professional Committee for Foot and Ankle Surgery of the Orthopedics Branch of Chinese Medical Doctor Association, Clinical Genetics Group of the Medical Geneticist Branch of Chinese Medical Doctor Association, Group of Genetic Disease Prevention and Control of Birth Defect Prevention and Control Committee of Chinese Society of Preventive Medicine have formulated a consensus on the diagnosis, classification and clinical treatment of calcaneal talus bridge based on research home and abroad, and experience on its clinical diagnosis and treatment of well-known experts, with an aim to provide a reference for clinical practice.
