Occipital calvarial bone graft in posterior occipitocervical fusion.

摘要: Study Design. Dorsal occipitocervical fusion is associated with a high rate of failure and requires an additional surgical site for donor bone graft harvesting. in this series, autologous occipital calvarial obtained from the same incision contoured metal loops was used 25 adults to achieve craniovertebral stabilization fusion. Objectives. To study use grafts Background Data. Cranial have been successfully craniofacial reconstruction good long-term results. In plastic surgery literature, there are claims that membranous superior endochondral fusions because decreased resorption. recent studies, results haves shown successful fusing upper cervical spine children. The posterior avoids many problems traditional sites provides sufficient quantity quality This especially true fragile rheumatoid arthritis patient cranial instability. Method. Split-thickness, loop cable instrumentation were mused patients, most whom had arthritis. harvested skull, using microair impactor, secured next construct. After surgery, all patients immobilized external orthoses. Results. None the, hardware or complications graft- procurement. 22 alignment, stability, bony on radiographs. Conclusions. Occipital appears work as well other corticocancellous routinely fusions.
