The control of pain after Keller's procedure--a controlled double blind prospective trial with local anaesthetic and placebo.

In patients undergoing bilateral Keller's arthroplasty the effect of injecting a long acting local anaesthetic into the pseudoarthrosis immediately after skin closure was compared to placebo into the other side in twenty patients. In a controlled double blind prospective trial, local anaesthetic proved to provide significantly better analgesia than the placebo and gave a lasting pain free interval. This procedure was simple, safe, inexpensive and free from complications.
