The Anatomical Basis of Nonuniform Settlement of the <scp>C2</scp> Lateral Mass and Its Association With Atlantoaxial Osteoarthritis
The macroscopic measurement of the axis specimens provided objective anatomic evidence for C2LM-NUS. Micro-CT showed that C2LM-NUS was associated with asymmetrical alterations of the trabecular microstructure of the lateral masses, suggesting that it is a pathological change rather than a normal phenomenon. The clinical study indicated that C2LM-NUS is an independent risk factor for AAOA. Stress concentration in unilateral alar ligaments and articular cartilage is a biomechanical contributor to AAOA.
