Allen Medical Systems Advanced Arm Support | Model A-70615-US | Specialized Spine and Neurology Surgical Positioner | Complete Upper Extremity Deck with Pressure-Redistribution Foam Pad | Used Condition

The Allen Medical Systems Advanced Arm Support (Model A-70615-US) is a professional-grade surgical table accessory expertly engineered to support and protect the patient's upper extremities during complex spine, orthopedic, and neurological procedures. Specifically optimized for prone and lateral positioning workflows, this system mounts directly to surgical table rails via an integrated clamp block. The positioner features a fully adjustable, low-profile body with an expandable arm platform to easily customize length based on patient anatomy. Accompanied by a multi-layer, contoured pressure-redistribution foam pad, it is designed to mitigate sheer pressures and prevent localized peripheral nerve compression during extended intraoperative intervals.
