Objective To investigate the clinical effect of closed reduction and anterograde double Kirschner wire intramedullary fixation on the fifth metacarpal shaft type A2 and B2 fractures in adolescents.Methods From July 2020 to June 2022,we treated 14 adolescent patients with the fifth metacarpal shaft fracture using closed reduction anterograde double needle intramedullary fixation,All patients were treated with closed reduction combined with C-arm fluoroscopy,and two Kirschner wires were inserted anteriorly on both sides of the proximal back of the fifth metacarpal bone.The tail of the Kirschner wire was buried subcutaneously,and a polymer splint was used to fix the fracture for 2 weeks postoperatively.Early functional exercise was performed.Postoperative follow-up:Outpatient clinic to observe the healing of the fracture end and the function of clenching and extending the little finger.Results All patients were followed up for 6～12 months,with an average of 9 months.All fractures healed,no infection was found in the buried incision at the tail of Kirschner wire,and the function of pinky finger clenching and extending recovered well after operation.Conclusion Closed reduction and antegrade double Kirschner wire intramedullary fixation for the treatment of the fifth metacarpal shaft fractures in adolescents has the advantaged of less trauma and reliable fixation.It is conducive to early functional exercise,reduce tendon scar adhesion and joint stiffness,and obtains satisfactory functional recovery effect of flextion and extension of the little finger in the later stage,it is a better method to treat the fifth metacarpal shaft fracture in adolescents.
