Peripheral neuropathy is the loss of sensation in the feet, and to a lessor degree in the hands. The cause of peripheral neuropathy can be from a number of different factors. In foot care, I look at peripheral neuropathy (PN) as a metabolic, physical or toxic issue.
The most common metabolic condition that contributes to PN is diabetes. But PN can also be the result of impingement of the nerve secondary to problems such as lumbar radiculopathy or focal nerve entrapments. And finally, PN can be secondary to toxic exposure such as alcohol abuse or exposure to toxic chemicals such as chemotherapy agents.
Idiopathic peripheral neuropathy is also found. The term idiopathic referres to a condition for which we cannot find a reason or etiology.
This discussion is interesting in that peripheral neuropathy contributed to joint instability and resulted in a subtalar joint dislocation. A subtalar joint dislocation is a rare injury that, in this case, was likely brought on by the lack of sensation surrounding the subtalar joint.
