Etiopathogenesis of diabetic foot include the following except
**Core Concept**
Diabetic foot is a common complication of diabetes mellitus, resulting from a combination of peripheral neuropathy, peripheral artery disease, and foot deformities. The etiopathogenesis of diabetic foot involves a complex interplay of factors, including impaired glucose metabolism, oxidative stress, and inflammation.
**Why the Correct Answer is Right**
Diabetic foot is primarily caused by peripheral neuropathy, which leads to loss of sensation and proprioception in the feet, making it difficult for patients to detect and respond to injuries or pressure sores. This is often accompanied by peripheral artery disease, which reduces blood flow to the feet, impairing wound healing and increasing the risk of infection. Additionally, foot deformities such as Charcot foot or hammertoes can also contribute to the development of diabetic foot.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because peripheral neuropathy is a key factor in the development of diabetic foot.
**Option B:** This option is incorrect because peripheral artery disease is also a crucial component of diabetic foot etiopathogenesis.
**Option C:** This option is incorrect because foot deformities such as Charcot foot or hammertoes are common in diabetic patients and can contribute to the development of diabetic foot.
**Clinical Pearl / High-Yield Fact**
A mnemonic to remember the common causes of diabetic foot is "NEPAS": Neuropathy, Edema, Pressure, Abscess, and Skin breakdown. This will help you to recall the key factors involved in the etiopathogenesis of diabetic foot.
**Correct Answer: A.**
