ReSolve Halo - Open Back Halo Ring, Model Number: 505400D The ReSolve Halo Ring is a fixation device used to immobilize a patient with a cervical spine injury.

Ossur initiated the recall after their investigation of some complaints found that in some instances the ceramic pins are difficult to screw through the halo ring.

Ossur contacted direct consignees and sub-accounts beginning on November 10 , 2008 via a phone call informing them of the recall, and the reason as stated in the public reason for recall. Consignees were asked to check their inventory for any of the identified products and contact them with this information. The firm developed a telephone script for the customer service representatives to use. Ossur then forwarded a notification letter to the affected customers beginning on November 12, 2008 via US Postal Service. In the event that any of these parts have already been applied to a patient, Ossur advised customers to follow their normal follow-up protocols, ensuring that the ceramic pins are properly fixed in the skull. At the time of the phone calls Ossur did not have sterilized open back replacement rings available; however, they offered their ReSolve Closed Back Halo ring as an alternative. The firm estimated that the normal product offering should be available once again in approximately four to six weeks from the date of the phone call.
