Purpose: The percutaneous treatment of bunionette deformity has been demonstrated as a reliable and satisfying technique with low risk of complications. However, there are some obvious variations in the surgical technique and perioperative protocol. The purpose of this study is to analyze the currently used techniques and to look for some agreements.
Hypothesis: There are some points of agreement in surgical technique and perioperative protocol when using a percutaneous technique to treat bunionette deformity.
Methods: A survey was sent to 50 orthopedic surgeons with specific experience in percutaneous techniques. The questions were related to different aspects of the surgical bunionette procedure and the perioperative protocol.
Results: A response rate of 92.0% was obtained. Several points of agreement were found. A condylectomy is rarely used while an osteotomy is performed in almost all procedures. This osteotomy is single (95.7%), complete (66.2-72.7%) and performed with a Shannon long burr (73.9%). The location of the osteotomy depends of the deformity (63.0%).
Discussion: This study demonstrates some consensus in the use of the surgical technique and the perioperative protocol. The percutaneous oblique osteotomy is the preferred technique while a condylectomy is only rarely used.
Level of evidence: V, Survey study.
