The Allen flex frame is a surgical extension for operating room (OR) tables that provides the positioning capabilities of a dedicated spine table, allowing for a variety of spine, cranial, and other surgical procedures. It supports the patient’s head, chest, abdomen, and hips for prone, lateral, and supine positioning, offers excellent C-arm access, and utilizes the OR table’s power for intraoperative flex. The system is known for its precise control over head and cervical spine adjustments and its compact storage design.
