Background. A study was designed to compare the efficacy of anesthesia between transthecal digit block (TDB) and single injection volar subcutaneous block. ⋯ These results confirm the efficacy of the transthecal block and the single injection volar subcutaneous digit block for achieving anesthesia of the finger, but the author prefers single injection volar digit block since it causes less pain during injection and the anesthesia lasts longer. .
