INSTRUCTIONS TO AUTHORS<br />
THE JOURNAL OF BONE & JOINT SURGERY · JBJS.ORG VOLUME 89-A · NUMBER 9 · SEPTEMBER 2007<br />
Authorship<br />
<strong>The</strong> order <strong>of</strong> names reflects only the preference<br />
<strong>of</strong> the authors. Each author must have<br />
contributed significantly to one or more<br />
aspects <strong>of</strong> the study: its design, data acquisition,<br />
analysis and interpretation <strong>of</strong> data,<br />
drafting <strong>of</strong> the manuscript, critical revision<br />
<strong>of</strong> the manuscript, statistical analysis, and/<br />
or study supervision. Each author should<br />
be able to defend and assume full responsibility<br />
for the content <strong>of</strong> the manuscript, regardless<br />
<strong>of</strong> the specific contributions. No<br />
more than six authors should be listed; individuals<br />
who have contributed to only one<br />
segment <strong>of</strong> the manuscript or have contributed<br />
only cases should be credited in an acknowledgment<br />
footnote. If there are more<br />
than six authors, an accompanying letter <strong>of</strong><br />
transmittal must detail why the authors<br />
have taken exception to these recommendations<br />
and should state how each author<br />
has contributed to the manuscript, with<br />
use <strong>of</strong> the criteria listed above.<br />
If a research group is designated as the<br />
author <strong>of</strong> an article, one or more group<br />
members who fully meet the above criteria<br />
for authorship should be listed in the article’s<br />
byline, followed by “on behalf <strong>of</strong> the<br />
[name <strong>of</strong> group].” <strong>The</strong> other group members<br />
should be listed in an acknowledgment<br />
section at the end <strong>of</strong> the article.<br />
Alternatively, the byline can include only<br />
the name <strong>of</strong> the group, followed by an asterisk<br />
corresponding to a list that specifies<br />
the authors who fully meet the above criteria<br />
for authorship and that also mentions<br />
the other group members.<br />

<strong>The</strong> <strong>Journal</strong> welcomes readers’ comments on<br />

Review <strong>of</strong> Manuscripts<br />

staff <strong>of</strong> <strong>The</strong> <strong>Journal</strong> and are sent to outside<br />

submitted manuscript and the decision<br />
regarding its publication has averaged six<br />
weeks, but it can be longer.<br />
