A Retrospective Analysis of Subaxial Subluxation Following Atlanto-axial Arthrodesis in Patients with Rheumatoid Arthritis Based on Annual Radiographs Obtained for Five Years.
Retrospective study. ⋯ Although SAA was maintained following atlanto-axial arthrodesis in RA-AAS patients, 12 of 25 patients (48%) with AAS developed SAS following atlanto-axial fusion. Further surgery was not needed for SAS up to five years after the initial surgery. We did not find any relationships between the occurrence of SAS and the AAA and SAA before and after surgery. Therefore, our findings suggest that proper reduction of AAA in patients with atlanto-axial arthrodesis does not affect the occurrence of SAS at five years after surgery.

Relation Between Severity of Injury and Neurological Deficit in Thoracolumbar Burst Fracture.
A prospective, consecutive case series. ⋯ NISS have a closer correlation with neurological deficit in thoracolumbar burst fractures; thus, we can put forward a hypothesis that perhaps NISS is able to reflect the dynamic fracture process.
