Objective To establish a comprehensive perioperative rehabilitation system for congenital polydactyly based on evidence-based medicine and multidisciplinary expert consensus， aiming to improve the standardization and precision of rehabilitation interventions. Methods A systematic literature search was conducted in accordance with PRISMA guidelines. The quality of evidence was evaluated using the GRADE approach， and three rounds of expert consultation were performed using a modified Delphi method to formulate recommendations. Results A total of relevant studies were included， and eight recommendations were developed， covering key aspects such as classification and diagnosis of polydactyly， preoperative preparation， postoperative rehabilitation， orthotic intervention， prevention of secondary deformities， and long-term follow up. Conclusion This consensus establishes a function-oriented， precise perioperative rehabilitation pathway， which contributes to improving structural and functional reconstruction of the hand， enhancing patients′ quality of life， and providing a standardized reference for clinical practice.
