ABSTRACT
OBJECTIVE: The objective was to describe the indications, technique, and initial outcomes of autologous rib graft with recombinant human bone morphogenetic protein (rhBMP) in pediatric patients undergoing posterior cervical fusion.
METHODS: A retrospective study was performed of all pediatric patients who underwent autologous rib grafting with extra-small rhBMP-2 for posterior craniocervical or cervical arthrodesis at a single institution between May 2020 and July 2023. Patients with less than 3 months of postoperative follow-up and no postoperative CT data were excluded. Primary outcomes included presence of fusion on CT, 30-day perioperative complications, and rib harvest complications.
RESULTS: Twenty-eight sequential patients met inclusion criteria. Thirteen were male, 15 were female, and the average age was 9 years. There were no surgical site infections or instances of postoperative seroma or unplanned return to the operating room. All patients had solid fusion on postoperative CT at 3 months. The average follow-up was 14.5 months, with a range of 4 months to 3 years. There were no complications associated with the rib harvest, including no instances of harvest site pain, and all patient incisions healed well.
CONCLUSIONS: The authors’ preliminary results demonstrate that autologous rib graft with extra-small rhBMP-2 is an effective strategy to achieve a high rate of fusion in pediatric patients undergoing posterior instrumented craniocervical or cervical fusion. In this series, the authors found an acceptable safety profile, without seroma, surgical site infection, unplanned return to the operating room, or rib harvest complications.
