Streamlining Iliac Bone Harvest for Maxillary Reconstruction With Novel Use of Arthrex Osteochondral Autograft Transfer System.

ABSTRACT

This study introduces a novel application of the Osteochondral Autograft Transfer System (OATS) for autologous bone grafting during alveolar cleft repair. Approximately 75% of patients with cleft lip and palate have an alveolar cleft, which often necessitates secondary bone grafting from common donor sites such as the iliac crest. Traditional harvesting techniques, although effective, can be labor-intensive and increase the risk of donor site injury. Here the authors describe the use of OATS, which has primarily been used in orthopedic procedures like anterior cruciate ligament reconstruction, for the first time in alveolar cleft repair. It involves a minimally invasive, single-use transfer system for harvesting osteochondral autografts from the anterior iliac crest, and thereby reduces harvest time compared with traditional open approaches. The procedure is detailed from pre-operative evaluation through long-term follow-up and highlights the technique's benefits related to surgical time, ease of use, and maintenance of sizable autograft volumes. Similarly, the authors discuss other advantages of OATS, including its single-use and cordless nature, which is believed to contribute to a lower contamination risk and better intraoperative ergonomics.
