Charcot joint
/dʒɔɪnt/
1. [noun] charcot joint , also known as a neuropathic joint or Charcot (neuro/osteo)arthropathy , refers to a progressive degenerative/destructive joint disorder in patients with abnormal pain sensation and proprioception. In modern Western societies by far the most common cause of Charcot joints is diabetes mellitus, and therefore, the demographics of patients matches those of older diabetics. Prevalence differs depending on the severity of diabetes mellitus. See: https://radiopaedia.org/articles/charcot-joint ; Accessed May 3 2019
Frequently Asked Questions
How does a neuropathic joint differ from typical joint wear you might experience during everyday walking?
In everyday activities like walking, a normal foot sends pain signals when stressed. In a neuropathic joint, diminished sensation means these signals are absent, allowing repeated stress to gradually compromise joint structure.
How do diminished sensory signals in the foot lead to progressive joint damage over time?
When the foot loses its ability to sense pain and position, everyday movements place unrecognized stress on joints. This continual stress without corrective feedback can lead to abnormal joint mechanics and gradual joint breakdown.
How does the etymology of 'neuro/osteoarthropathy' help in remembering the nature of this joint condition?
The term combines 'osteo' (bone) and 'arthro' (joint) with 'neuro' (nerve), emphasizing that abnormal nerve function in the foot contributes to destructive processes affecting both bones and joints, a helpful cue for remembering its degenerative character.
