An error appeared in the Proceedings in the summary of the paper presented by Dr. Gerald G. Gill, Dr. John G. Manning, and Dr. Hugh L. White, entitled Surgical Treatment of Spondylolisthesis without Spinal Fusion (Excision of the Loose Lamina with Decompression of the Nerve Roots) as published in the June issue of The Journal.
On page 684, paragraph 3, line 4, the phrase "and, where indicated, a superior facetectomy", and on the same page, paragraph 6, line 2, the phrase "with superior facetectomy, occasionally" should have been omitted.
It is suggested that a line be drawn through these phrases by the reader in his June issue.
