AI Article Synopsis
- The study examined the effects of the Intramedullary Bone Endoscopy (IBE) procedure on the blood supply in the cavity of long bones using a sheep model.
- Out of 10 sheep subjected to the IBE procedure, only one showed minimal endosteum damage, which did not affect cortical blood flow.
- The findings suggest that while there is a slight risk of endosteum damage during IBE, it is limited and the procedure could be safely used for treating localized bone issues, like osteomyelitis or benign tumors.
Article Abstract
This study investigated whether the Intramedullary Bone Endoscopy (IBE) procedure within the cavity of an intact long bone will interfere with the local endosteal blood supply. In a sheep model, 10 animals underwent the IBE procedure with complete perioperative anaesthesiology monitoring. After the femora were harvested, histological analysis was performed to examine destruction of the endosteum and consecutive reduction in perfusion. Only one animal showed evidence of detachment of the endosteum with destruction of several microns of the endosteum, although this did not interfere with the cortical perfusion. None of the vessels were occluded by fat or other causes of occlusion, e.g. blood coagulation. Our findings indicate that with the IBE procedure under visual control there is a potential risk to damage the endosteum. However, the interference was limited to a small part of the endosteum and did not lead to a reduction in the cortical perfusion. Clinical use could be in localized intramedullary lesions such as osteomyelitis or benign bone tumours.
