摘要：

Magnetic resonance images of 276 TM joints in 138 symptomatic patients were analyzed in a retrospective study to determine the condylar shape and size and to correlate it with internal derangement. Internal derangement by MRI was noted in 66% of the TM joints. Our study demonstrates that the regressive condylar changes in TM joints with internal derangement were more common (61%) than proliferative bony changes (39%). On the converse, none of the TM joints with regressive condyles revealed normal disc. The altered bony morphology also correlated with the severity of internal derangement, i.e. bony changes in TM joints with anterior closed lock were noted in 64% compared to 45% with reducible disc. The cause and effect relationship of the regressive condylar remodeling and disc abnormality is not clear and needs further study. © 1990.
