The Allen® Intraoperative Arm Positioner is a small, lightweight arm positioner that attaches over the drape and provides positioning of the arm intra-operatively. The positioner delivers arm positioning for shoulder surgery in the Beach Chair position, as well as elbow and clavicle procedures. By indexing at the elbow, the device is able to gain complete positioning control of the shoulder joint. The product's design allows the entire device to be steam sterilized and provide greater access to the surgical site. The device also has the capability of achieving a semi-locked state, allowing the surgeon to move the arm without having to adjust the tension.
