Abstract

Abstract Background: Scaphoid nonunion result in a predictable pattern of wrist arthrosis. To minimize the incidence of arthrosis, the goal of treatment should be consolidation of the fracture of the scaphoid in anatomic alignment. Aim of Study: To evaluate different means of treatment of scaphoid nonunion and evaluate its clinical results. Patients and Methods: This study was conducted at EL-Helmya Military Hospital and Kasr El-Ainy Hospital during the period from 2011 to 2016 on fifty patients diagnosed as non-united fracture scaphoid and operated upon by fixation and graft if needed, then followed-up for a period of at least 18 months. Patients were 49 male and one female with an average age of 23 years. All operative management and follow-up. Results: This study proved that operative treatment of scaphoid nonunion can be summarized as follows: Grade I,II,III according to Slade and Geissler`s classification can be treated by percutaneous or open fixation by Herbert screw even if the nonunion in prox. Pole. Grade IV/V/VI we have to open volarly for waist or dorsally for prox. Pole and fixation with bone graft from iliac crest or distal radius. Conclusion: This study proves that the goal of treatment of scaphoid nonunion should be consolidation of the fracture in anatomic alignment. scaphoidnonunions with severe collapse and humpback deformity must be approached volarly with interposition of an intercalary bone graft and internal fixation. A dorsal approach to proximal scaphoid nonunions allows immediate access for removing the necrotic bone from small proximal pole nonunions and internal fixation.
