    Description of Event or Problem · 1

    IT WAS REPORTED IN A LITERATURE PUBLICATION THAT BETWEEN APRIL 2003 AND AUGUST 2008, A SINGLE SURGEON PERFORMED CDA ON A TOTAL OF 55 PATIENTS. THE PATIENTS HAD CERVICAL RADICULOPATHY, CERVICAL MYELOPATHY, OR BOTH, CAUSED BY DEGENERATIVE DISC DISEASE THAT HAD NOT RESPONDED TO NON-OPERATIVE MANAGEMENT. FOR THE PURPOSES OF REPORTING, THE THREE PATIENTS WHO HAD RADICULOPATHY AS WELL AS MYELOPATHY WERE GROUPED WITH THOSE WHO HAD MYELOPATHY, ON THE GROUNDS THAT MYELOPATHY WAS THE MORE SERIOUS CONDITION. THE RADICULOPATHY GROUP CONSISTED OF 23 MALES AND 14 FEMALES WITH AN AVERAGE AGE OF 48, THE MYELOPATHY GROUP 12 MALES AND 6 FEMALES WITH AN AVERAGE AGE OF 42. SEVERAL CDA DEVICES WERE USED AT THE DISCRETION OF THE SURGEON OUTCOME DATA WERE NOT AVAILABLE FOR FOUR OF THE 55 PATIENTS, WHO WERE LOST TO FOLLOW-UP. OF THE REMAINING 51 PATIENTS, FIVE SUFFERED TECHNICAL OR PATHOLOGIC FAILURES AFTER INITIAL TREATMENT, AND HAD TO UNDERGO RESCUE TREATMENT. THEIR EVENTUAL TREATMENT INVOLVED MORE THAN CDA. THEREFORE, BECAUSE THEIR CLINICAL OUTCOMES COULD NOT BE ATTRIBUTED SOLELY TO USING CDA, THESE PATIENTS WERE NOT INCLUDED IN THE GROUP OUTCOME DATA. HOWEVER, THEY WERE INCLUDED IN THE ESTIMATIONS OF SUCCESS RATES FOR CDA, IN WHICH REGARD THEY WERE CLASSIFIED AS HAVING NOT HAD A SUCCESSFUL OUTCOME. THE REMAINING 46 PATIENTS PROVIDED OUTCOME DATA REFLECTIVE OF THE USE OF CDA ALONE. THREE OF THE FIVE FAILURES HAD SIGNIFICANT ADJACENT SEGMENT DISEASE AT THE TIME OF THE CDA, WHICH SUBSEQUENTLY BECAME SYMPTOMATIC. TWO DEVELOPED SYMPTOMS AT THE INDEX LEVEL ¿ INADEQUATE DECOMPRESSION MAY HAVE PLAYED A ROLE. THERE WERE NO DEVICE FAILURES. PATIENT 5 UNDERWENT AN INITIAL PROCEDURE FOR CERVICAL ARTHROPLASTY WITH IMPLANT OF AN ARTIFICIAL CERVICAL DISC AT C5-C6. POST-OP THE PATIENT HAD SYMPTOMS OF WORSENING MYELOPATHY FROM POSTERIOR DISC/OSTEOPHYTE COMPLEX AT C4-C5. PATIENT UNDERWENT A SECONDARY OPERATION FOR ACDF AT C4-C5.
