The Allen® Intraoperative Arm Positioner™ is a small, lightweight arm positioner for any shoulder procedure in the Beach Chair position. It 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 provides an unprecedented level of access to the surgical site. The device also has the capability of achieving a semi-locked state, allowing the surgeon to simply move the arm where he wants it without having to adjust the tension.
