An instrument used during orthopaedic surgery to perform traction on the cervical spine by applying an upward force to the skull that causes hyperextension of the head and neck. It is typically a two-arm pivoted instrument that is attached to the skull using pins (either partially implanted or not); the proximal end includes a mechanism (e.g., an adjustable threaded bolt and nut) responsible for the application of the traction force. This device is typically used during procedures to treat a fractured spine. This is a single-use device.
