Insights
Natural coral effectively substitutes bone grafts for spinal fusion in children, reducing bleeding and the need for blood transfusions. This innovative approach shows promising results, similar to traditional bone grafts.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Pediatric Spine Surgery
Context:
- Posterior vertebral fusion is a common procedure in pediatric spine surgery.
- Bone grafts are traditionally used for vertebral fusion, but carry risks such as donor site morbidity and the need for blood transfusions.
- Minimizing peroperative bleeding and allogeneic blood transfusions are key goals in pediatric spinal surgery.
Purpose:
- To evaluate the efficacy and safety of using natural coral as a bone graft substitute in pediatric posterior vertebral fusion.
- To assess the potential of natural coral to reduce peroperative bleeding and the need for homotransfusion.
- To describe the surgical technique and outcomes associated with using natural coral grafts in instrumented spinal fusion.
Summary:
- This study investigated the use of natural coral as a bone graft substitute in 49 children undergoing posterior vertebral fusion with the Cotrel-Dubousset device.
- Results, assessed via X-ray, scintigraphy, and biopsy, demonstrated that natural coral behaves similarly to conventional bone grafts.
- The protocol aimed to decrease peroperative bleeding and avoid blood transfusions, with encouraging outcomes observed.
Impact:
- Natural coral presents a viable alternative to traditional bone grafts in pediatric spinal fusion.
- The use of coral grafts may lead to reduced surgical complications, including blood loss and transfusion requirements.
- This biomaterial holds potential for wider application in various forms for spinal reconstruction.
Abstract:
The authors used natural coral as a substitutive element to bone supply in children in need of posterior vertebral graft. The use of natural coral was part of a protocol aiming at diminishing peroperative bleeding, and as far as possible, at doing away with resorting to homotransfusion. After reviewing the biological, experimental and clinical bases, the authors studied 49 cases of posterior vertebral fusion instrumented with the Cotrel-Dubousset device and with natural coral grafts. Results were appraised with X-ray in all cases, 5 times with scintigraphies and 7 times with biopsies and were encouraging: coral behaves quite similarly to the usual bone graft. From their experience the authors describe how coral is to be used and consider that the use of this substitutive element should spread in the future under various forms.
