Tantalum Spacer Augmentation of Large Bony Defects in Hindfoot Arthrodesis

Video Transcription

Video Summary

In this video, Connor Delman, an orthopedic surgery resident at UC Davis, presents on tantalum spacer augmentation and hindfoot orthodesis of large bony defects. The study aimed to assess the efficacy, radiographic outcomes, and complications associated with tantalum spacer use in hindfoot orthodesis. The retrospective review included patients with large hindfoot osseous defects treated with subtalar or tibiotelocalcanearthrodesis. The surgical technique involved fibular osteotomy or distraction subtalar orthodesis with the tantalum central core filled with autograft and orthobiologic proteins. Out of 12 patients, 10 achieved successful orthodesis with an 83% union rate at 6 months. This study suggests that porous tantalum spacers provide a reliable structural graft option in patients with large hindfoot defects.
