What are the recommended entry angles for harvesting from the ASIS using the OsteoAuger Bone Graft Harvesting System?

The recommended entry angle for harvesting from the Anterior Superior Iliac Spine (ASIS) using the OsteoAuger Bone Graft Harvesting System is 25 degrees medial to the parasaggital line. This specific angle is significant because it optimizes the trajectory for bone graft harvesting, ensuring adequate access to healthy bone material while minimizing the risk of damaging surrounding structures and vessels.

Choosing the appropriate angle is critical in achieving a successful harvest, as it allows for efficient penetration into the cancellous bone and enhances the possibility of retrieving high-quality graft material. The 25-degree angle strikes a balance by providing sufficient depth and stability during the procedure.

In contrast, other angles proposed might lead to complications, such as undue stress on surrounding tissues or insufficient graft quality. Ensuring the use of the correct angle is essential for the effectiveness and safety of the harvesting process, making the choice of 25 degrees the best practice in this scenario.
