JOA score RR after CCF and its outcome.
| Operative Procedures | Improved | Pre-Op. JOACMEQ Score | Post-Op. JOACMQ Score | JOA Score RR (%) | Bony Fusion of Joints | Stabilization of Joints |
|---|---|---|---|---|---|---|
| Neurological Symptoms/Signs | (Mean with ± One SD) | (Mean with ± One SD) | ||||
| CCF: 30 cases | 27/30 (90.0%) | 4–15 (9.7 ± 2.48) | 10–17 (15.5 ± 2.51) | 69.7% | 21/30 (70.0%) | 25/30 (83.3%) |
| C1/2 FIX 16 cases | 15/16 (93.8%) | 4–12 (9.0 ± 2.55) * | 14–17 (15.4 ± 2.58) | 78.7% * | 12/16 (75.0%) * | 15/16 (93.8%) * |
| OCF 14 cases | 12/14 (85.7%) | 3–12 (6.4 ± 2.43) ** | 10–17 (15.7 ± 2.48) | 63.5% ** | 9/14 (64.3%) ** | 10/14 (71.4%) ** |
*: significantly higher than OCF (p < 0.01). **: signify lower than C1/2 FIX (p < 0.01). Abbreviations: JOACMQ = the recovery rate of Japanese Orthopaedic Association Cervical Questionare, JOA score RR= recovery rate of JOACMQ, SD = standard deviatein, CCF = craniocervocal fixateon, C1/2 FIX = atlanto-axial posterior lateral fixateon, OCF = occipito-cervical fixateon.
