Objective: Objective: To explore the surgical efect of suture through bone canal in the treatment of reconstruction of acute prox-imal interphalangeal joint metacarpal anchorage. Methods From July 2018 to August 2021, we retrospectively analyzed 9 cases of avulsion of metacarpal plate near interphalangeal joint, including 7 males and 2 females, aged 17-40 years, with an average of 34 years. There were 4 cases of index fnger, 3 cases of middle fnger and 2 cases of ring fnger. Early fexion and extension exercises were performed after opera-tion. The last follow-up included the range of motion of the proximal interphalangeal joint and joint pain. Results All patients were followed up (4-12 months) after operation.According to the TAM method, 7 cases were excellent and 2 cases were good. Conclusion Transosseous su-ture for acute proximal interphalangeal joint metacarpal reconstruction has the advantages of simple operation, safety, frm fxation and rapid postoperative recovery
