Abstract

The "anchovy" interpositional arthroplasty technique can be used as a salvage option for failed hallux rigidus procedures. The operative technique utilized by the senior author is described. Careful soft-tissue handling, meticulous joint space and graft preparation, and interposition graft stabilization using a bone tunnel and suture anchors are unique aspects of this technique, which in the authors' experience have contributed to improved outcomes. Current literature regarding indications and outcomes is limited and controversial. The proposed benefits of soft-tissue interposition arthroplasty of the hallux metatarsophalangeal joint for patients with prior failed implant arthroplasty are improved pain scores and preservation of range of motion. Level of Evidence: Level V, technique guide.
