AAOS approves two technology overviews

Two new technology overviews—one focusing on synthetic bone void fillers and the other covering cervical disk arthroplasty—were presented to the AAOS Board of Directors during its meeting on March 9. Kristy L. Weber, MD, chair of the Council on Research, Quality Assessment, and Technology, presented the documents, which were developed by physician workgroups under the direction of the Guidelines and Technology Oversight Committee.

The technology overview of cervical disk arthroplasty looked at the procedure in comparison to anterior cervical diskectomy and fusion, examining the literature for patient characteristics, clinical outcomes, revision and complication rates, and cost-effectiveness. The work group, chaired by Michael R. Zindrick MD, included Mitchel B. Harris, MD; Steven Craig Humphreys, MD; Patrick T. O’Leary, MD; and Gary A. Schneiderman, MD.

The overview on synthetic bone fillers examined the issue of clinical outcomes when bone void fillers are used in posterolateral spine fusion, metaphyseal defects, contained defects from tumor (or other benign bone cysts), and contained defects from periprosthetic bone loss. Work group members included John S. Kirkpatrick, MD, chair; Charles N. Cornell, MD; Bang H. Hoang, MD; Wellington Hsu, MD; and J. Tracy Watson, MD.

Technology overviews do not make recommendations for or against the use of a particular technology; rather, they are considered educational tools that encourage readers to consider the information presented and reach their own conclusions. Details will be published in next month’s issue of AAOS Now.

Editor’s note: The list of work group members who developed the Clinical Practice Guideline for the Diagnosis and Treatment of Acute Achilles Tendon Ruptures, published in the March issue of AAOS Now, inadvertently omitted the name of Eric Michael Bluman, MD, PhD. AAOS Now regrets the omission.
