What is the primary purpose of intra-operative fluoroscopy during total shoulder arthroplasty (TSA)?

The primary purpose of intra-operative fluoroscopy during total shoulder arthroplasty (TSA) is to verify the placement of components during surgery. This imaging technique provides real-time visualization, allowing the surgeon to confirm that the implants are correctly positioned before finalizing their placement. Accurate positioning of the humeral head and glenoid components is crucial for the long-term success of the surgery, as it can directly impact the joint's function and stability.

The use of fluoroscopy allows for immediate feedback, which helps the surgical team make any necessary adjustments before concluding the procedure. This real-time imaging is particularly beneficial in complex cases or in conditions where conventional visibility may be compromised. Other options, while relevant to the surgical process, do not align with the specific function of intra-operative fluoroscopy, which focuses on imaging component placement rather than enhancing visibility, monitoring vital signs, or assisting in anesthesia.
