Abstract: Objective To investigate the clinical effect of soft tissue reconstruction in the treatment of crab-claw finger deformity in children．Methods From January 2019 to December 2022,soft tissue reconstruction was performed in 25 patients with crab-claw finger deformity or “Z-shaped” deformity after surgery,and Tada score and complications were observed one year after surgery．Results One year after surgery,16 of 25 children had excellent Tada scores（64%）,8 of 25 had good scores（32%）,and 1 had poor score（4%）．The Peds QL score 1 year after operation（92.74±9.52）was significantly higher than that before operation（79.25±7.43）,and the difference was statistically significant（P<0.001）．Dysextension of interphalangeal joint and delayed fracture healing occurred in 1 case,the total complication rate was 8%．Conclusions In the treatment of crab-claw finger deformity and soft tissue reconstruction,children do not need to undergo one-stage resection of the repetitive thumb,second-stage osteotomy and orthopedic surgery or multiple operations to remove extra fingers,and just only one operation is needed to complete the osteotomy and orthopedic surgery of crab-claw finger,which has the advantages of short treatment cycle,less pain for children and low economic cost for families．It significantly improves the quality of life of children and has satisfactory clinical effects．
