What is the size range for a shoulder spica bandage?

The size range for a shoulder spica bandage being 4 inches to 5 inches is appropriate due to the specific anatomical requirements of effectively securing the shoulder and providing adequate support to the surrounding structures. A bandage within this size range is large enough to cover the shoulder joint adequately and allow for adjustment around the torso and upper arm, ensuring stability during movement or rehabilitation.

Smaller widths would not provide the necessary coverage and support, making them insufficient for this particular application. Likewise, larger widths might be unwieldy and difficult to manage, potentially leading to discomfort or ineffective immobilization. Thus, the 4 inch to 5 inch range is best suited for achieving both effective support and patient comfort.
