To the Editor: There is a technical error concerning thermography in the editorial (1) published in the 1 December 1989 issue. The fourth sentence of the second paragraph on page 867 should have read: "The observation that sciatic nerve irritation may result in lower surface skin temperatures has resulted in the use of liquid crystal and computed thermography of the lower extremities."
