text: The control of pain after Keller's operation by the instillation of local anaesthetic before closure. A prospective controlled trial.
  With the aim of controlling pain after Keller's operation, a solution of a long-acting local anaesthetic was instilled into the field before closure in a series of thirty patients. In a controlled prospective trial this simple technique by itself proved to be significantly better than either foot block at the ankle or the usual analgesics and was free from local or systemic complications.
