COMPRESSION NEUROPATHY

ABOUT COMPRESSION NEUROPATHY

Compression neuropathy is a focal peripheral nerve disorder caused by mechanical pressure or constriction on a single nerve or nerve trunk, most commonly at anatomical “tight” sites such as the carpal tunnel, cubital tunnel, or tarsal tunnel. It typically presents with localized pain, tingling, numbness, and sometimes weakness in the nerve’s distribution, often worsened by certain postures or repetitive activities; in more severe or chronic cases, it can lead to muscle atrophy, loss of fine motor control, and increased fall risk.

The underlying pathophysiology involves mechanical deformation of the nerve sheath and axons, which disrupts microvascular blood flow, alters ion‑channel function, and triggers local inflammation, with secondary contributions from mitochondrial dysfunction and oxidative stress as impaired axonal transport and energy metabolism promote axonal degeneration and abnormal nerve signaling.

Compression neuropathies are among the most common peripheral nerve disorders in the United States, affecting millions of people annually - especially those with repetitive occupational tasks, obesity, diabetes, or anatomical predispositions - and while conservative measures (splinting, activity modification) and surgical decompression can relieve symptoms and prevent progression in many cases, there are currently no approved disease‑modifying pharmacologic therapies that specifically regenerate or repair the underlying nerve damage once established.[1][2][3][4][5][6][7]
