| Scientific title | The Delphi Trial I(RCT)2 international randomised clinical trial of rheumatoid craniocervical treatment: an intervention-prognostic trial comparing 'early' surgery with natural history |
| Study acronym | The Delphi I(RCT)2 |
| Study objectives | There is no difference between early surgery and prolonged conservative treatment. The prevalence of rheumatoid arthritis is 0.8 - 1%. The upper cervical spine shows signs of damage in 17 - 86% of patients with rheumatoid arthritis (RA). Once neurological deficits develop prognosis is poor. Surgery is advocated by most international centres in an early stage to prevent neurological deterioration and radiological progression of abnormalities. |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Rheumatoid arthritis |
| Intervention | Early surgery versus prolonged conservative treatment: 1. Surgical treatment (A) Operation technique: C1C2 screw fixation according to Magerl or Harms with or without wiring techniques 2. Prolonged conservative treatment (B): The treatment of rheumatoid arthritis patients is aimed primarily at rapid reduction of disease activity by disease-modifying anti-rheumatic drugs, thus preventing (progression of) damage, including subluxation, and maintenance/restoration of physical (including neurological) function |
