Release of the fibro-osseous tunnels is performed for entrapment neuropathy and stenosing tenosynovitis which occur as a result of increase in the volume/pressure within these tunnels. The common surgical principle in all these pathologies is releasing the pressure by transecting the fascial covering. Primarily these pathologies are treated with open surgery but are potentially amenable to curative percutaneous ultrasound (US) guided release procedures. US is the preferable guiding modality due to its high resolution and real-time demonstration of the anatomy and needle positioning. The advantages of these minimally invasive techniques are lower risk of wound breakdown, quicker healing, reduced post-procedural pain, reduced complications, and a quicker return to normal activity. The release of the tunnel may be achieved by sectioning the thickened pulley or retinaculum with the aid of the needle bevel or surgical-grade thread which are universally available, economical, and equally effective.
