Abstract
A method of performing trigger finger release surgery. A flexor tendon (T) passes through the palm (P) of a person's hand (H) to a finger (F) or thumb (B) . For a person suffering from trigger finger, the path (1) of the impaired tendon is first identified. Constriction of a protective sheath (E) around the flexor tendon causes the trigger finger condition. A puncture site is identified for insertion of one end of a hollow surgical instrument (1) into the palm. The surgical instrument is pushed through the palm of the hand so that a first puncture hole (U) is made where the instrument enters into the palm, and a second puncture hold (U') where the instrument exits from the palm. The instrument is routed through the palm such that the path (8) of the instrument passes through the sheath. The surgical instrument is left in place and an arthroscope (9) and a surgical knife (11) are inserted into respective ends of the instrument. The surgeon views the surgical site through a monitor (10) while cutting the sheath with the knife. The arthroscope, knife, and surgical instrument are then withdrawn. The size of the surgical instrument is such that after its withdrawal, the puncture holes made in the hand do not require stitches to close them. As the wounds heal, no scars are formed.
