Abstract
The results of 20 established nonunions of the scaphoid treated with resection of the pseudoarthrosis, anterior cortic-cancellous iliac bone grafting, and conventional lag screw fixation with the ASIF 2.7 mm cortical screw are presented. Union rate was 95% and the average time off work was 8.9 weeks. Review of the relevant literature uniformly shows that the most common reasons for failure are improper internal fixation techniques and/or the absence of bone grafting. Successful treatment of scaphoid nonunions with screw fixation and cast-free after-treatment does not depend on the implant used but rather on careful case selection and precise surgical technique.
