Postherpetic neuralgia (PHN) is neuropathic pain that occurs due to damage to a peripheral nerve caused by the reactivation of the varicella zoster virus (herpes zoster, also known as shingles). Typically, the nerve pain (neuralgia) is confined to an area of skin innervated by a single sensory nerve, which is known as a dermatome. PHN is ...
Tarsal tunnel syndrome (TTS) is a nerve compression syndrome or nerve entrapment syndrome causing a painful foot condition in which the tibial nerve is entrapped as it travels through the tarsal tunnel. [1] [2] The tarsal tunnel is found along the inner leg behind the medial malleolus (bump on the inside of the ankle). The posterior tibial ...
In people with diabetic peripheral neuropathy, two reviews make a case for nerve decompression surgery as an effective means of pain relief and support claims for protection from foot ulceration. [114] [115] There is less evidence for efficacy of surgery for non-diabetic peripheral neuropathy of the legs and feet. One uncontrolled study that ...
Lower limb. Foot. Cutaneous innervation of the lower limbs is the nerve supply to areas of the skin of the lower limbs (including the feet ) which are supplied by specific cutaneous nerves . Modern texts are in agreement about which areas of the skin are served by which nerves , but there are minor variations in some of the details.
Tabes dorsalis is a late consequence of neurosyphilis, characterized by the slow degeneration (specifically, demyelination) of the neural tracts primarily in the dorsal root ganglia of the spinal cord (nerve root). These patients have lancinating nerve root pain which is aggravated by coughing, and features of sensory ataxia with ocular ...
Nerve conduction studies and electromyography are commonly used to evaluate large myelinated sensory and motor nerve fibers, but are ineffective in diagnosing small fiber neuropathies. [14] Quantitative sensory testing (QST) assesses small fiber function by measuring temperature and vibratory sensation. Abnormal QST results can be attributed to ...
a lateral branch which passes anteriorly superficial to the second intermetatarsal space to give rise to the give rise to the lateral digital dorsal nerve of the second toe, and the medial digital dorsal nerve of the third toe. [1] It also supplies the integument of the medial side of the foot and ankle. [citation needed] [verification needed]
Peroneal nerve paralysis is a paralysis on common fibular nerve that affects patient’s ability to lift the foot at the ankle. The condition was named after Friedrich Albert von Zenker . Peroneal nerve paralysis usually leads to neuromuscular disorder, peroneal nerve injury, or foot drop which can be symptoms of more serious disorders such as ...
