endplate sclerosis
Increased bone density and hardening of vertebral endplates seen on imaging studies.
Full Definition
Endplate sclerosis refers to the pathological thickening and increased density of the superior or inferior vertebral endplates, typically visible on radiographs and MRI as areas of increased signal on T1-weighted images. This condition often develops as a response to degenerative disc disease, mechanical stress, or previous infection. Sclerotic endplates can complicate spinal fusion procedures by impeding bone graft incorporation and may require specialized preparation techniques during surgery to achieve successful arthrodesis.
Usage
Usage note: Specify endplate location (superior/inferior) when documenting.
