Intervertebral disc degeneration is a significant contributor to back pain and a leading cause of disability worldwide. Numerous animal models of intervertebral disc degeneration exist. We demonstrate an ovine model of intervertebral disc degeneration, utilizing a drill bit, which achieves a consistent disc injury and reproducible level of disc degeneration.

Typically, CVADs terminate in the superior vena cava, just outside of the right atrium of the heart, but they may also terminate in any one of the great veins (i.e., aorta, inferior vena cava, brachiocephalic...

FAQs
The route approaches target structures from behind the peritoneal lining rather than crossing the abdominal cavity. This can reduce the need to manipulate organs within that cavity while preserving a direct path toward retroperitoneal anatomy. The distinction matters when planning minimally invasive procedures because the chosen corridor determines both the structures encountered and the available working space.
Insufflation helps establish room within the developed retroperitoneal space for visualization and instrument movement. Because this compartment is confined, creating a controlled working area is central to maintaining a usable operative field. The relationship between insufflation, spatial limits, and visualization therefore influences how effectively surgeons can reach and work around retroperitoneal structures.
Planning must account for the flank or posterior abdominal wall entry route and the position of the intended target. The retroperitoneum contains structures with different surgical roles, including kidneys, adrenal glands, ureters, the aorta, and the spine. Mapping the pathway helps align the access point with the procedure while respecting the region’s confined anatomy.
The key distinction is the compartment used to reach the target. Retroperitoneal access develops a pathway behind the peritoneal lining, whereas an abdominal-cavity approach enters the intraperitoneal compartment. This difference can limit manipulation of intraperitoneal organs and may provide more direct access to selected posterior abdominal, vascular, urinary, adrenal, or spinal structures.
A typical sequence begins with creating an entry through the flank or posterior abdominal wall, followed by development of the retroperitoneal space. Insufflation then helps create room for instruments and visualization. The procedure depends on maintaining a controlled pathway in a confined region, so access planning and careful spatial orientation are integral to the workflow.
Its applications include selected nephrectomy, adrenalectomy, vascular repair, and spinal interventions. The approach is relevant when the operative target lies behind the peritoneal lining and a posterior corridor may be useful. Choice of route remains procedure-specific because the anatomy, limited working space, and need for precise technique affect how safely and effectively the target can be reached.
