Abstract:  Objective    To investigate the clinical efficacy of scaphoid nonunion with autogenous bone graft fixed by multiple Kirschner Wires through small radial incision of carpal.    Methods    From January 2008 to January 2018, 19 cases of scaphoid nonunion were treated with multiple Kirschner wires fixation and autologous bone grafting through small radial incision centered on the radial styloid process, including 15 males and 4 females. The age ranged from 25 to 54 years, with an average of 37.6 years. The treatment time of patients after injury ranged from 3 to 32 months, with an average of 15.1 months. After the operation, the thumb and forearm were immobilized with a tube cast for 12-16 weeks.   Results   All the incisions were healed in one stage. Fracture union occurred in 17 cases and non-union in 2 cases,  union rate was 89.5%. Clinical healing time ranged from 12 to 16 weeks, with an average of 14.5 weeks. Postoperative modified Mayo wrist score (76.3±8.7) was significantly improved compared with preoperative score (54.1±9.6), χ2= -6.780, P=0.000, with significant difference.    Conclusions   Multiple Kirschner wires fixation and autologous bone grafting through small radial incision of carpal is an effective method with less injury, full exposure and high fracture healing rate.
