Carpal Tunnel Syndrome Surgery Indications
Open carpal tunnel release is indicated in patients with carpal tunnel syndrome who meet one or more of the following criteria:
Failure of conservative treatment
β Persistent symptoms (pain, numbness, paresthesia) despite β₯6β12 weeks of non-surgical management (splinting, NSAIDs, steroid injections).
Severe clinical signs
β Thenar muscle atrophy
β Weakness in thumb abduction or opposition
β Persistent or worsening sensory loss
Electrodiagnostic confirmation of severe median neuropathy
β Markedly slowed nerve conduction across the carpal tunnel
β Evidence of axonal loss (reduced CMAPs/SNAPs)
Acute carpal tunnel syndrome (e.g., post-traumatic, hematoma, infection)
β Requires urgent decompression, usually via an open approach
Recurrent or persistent CTS after endoscopic release
β Open revision provides better visualization of residual compression
Surgeon or anatomical preference
β Open approach may be favored in cases with:
β Anomalous anatomy
β Space-occupying lesions (e.g., lipoma, ganglion)
β Prior wrist surgery or scar tissue
