We report the successful use of tekmiron thread instead of wire for atlanto-axial subluxation in two cases. The atlanto-axial instability was caused by rheumatoid arthritis in one, and by an old dens fracture in the other. Bony union was acquired within four months after surgery, and the atlanto-axial subluxation disappeared radiographically in both cases. We recommend the use of tekmiron thread for atlanto-axial fixation.
