Abstract:
Carpal tunnel syndrome is the most common nerve entrapment in the upper limb and carpal tunnel release (CTR) provides the most predictable outcome and relief of symptoms. Incomplete carpal tunnel releases are uncommon, however, in the event of incomplete surgical releases, symptoms following such incomplete releases tend to be more severe than the symptoms presented at the initial complaint. We present our experience in utilizing high definition ultrasound to reliably and accurately localize the anatomical cause to aid focused revision CTR.
