<p>Study Design. A retrospective follow-up study of conservatively treated patients with mild cervical myelopathy caused by cervical soft disc herniation. Objective. To investigate the outcome of conservative treatment for patients with mild myelopathy caused by cervical soft disc herniation and to evaluate usefulness of magnetic resonance findings in the prediction of the outcomes. Summary of Background Data. Recent studies on conservative treatment of cervical soft disc herniation have focused mainly on radiculopathy, and not on myelopathy. Methods. Twenty-seven patients with mild cervical myelopathy secondary to cervical soft disc herniation were treated conservatively for more than 6 months by cervical bracing and restriction of daily activities. Of the 27 patients, 17 patients (Group A) underwent conservative treatment only and it was associated with improvement in their neurologic deficits, while the other 10 patients (Group B) ultimately underwent decompression surgery because of neurologic deterioration. Comparisons between the two groups were made in regard to JOA score, patient satisfaction, and magnetic resonance findings, including location of the disc herniation (focal or diffuse in the sagittal plane, median or paramedian in the axial plane). Results. The JOA scores were 13.6 ± 1.6 in Group A and 14.1 ± 1.6 in Group B before treatment, 14.9 ± 1.0 and 12.9 ± 2.1, respectively, at 3 months, and 16.2 ± 0.8 and 16.0 ± 1.2, respectively, at the final follow-up. The JOA scores at 3 months were significantly lower in Group B than in Group A. Satisfaction with the results of treatment at the final follow-up was reported by 77% of the patients in Group A and 90% in Group B. Focal-type herniation was present in 47% of the patients in Group A and 70% in Group B, while median-type herniation was diagnosed in 77% in Group A and 30% in Group B. Follow-up magnetic resonance imaging of the patients in Group A showed spontaneous regression of a herniated mass in 10 patients (59%), Diffuse-type herniations were more likely to regress spontaneously than focal-type herniation (78% vs. 37%). Conclusions. Conservative treatment is an effective treatment option for mild cervical myelopathy caused by cervical soft disc herniation. A good outcome can be expected in patients with a median-type and/or diffuse-type herniation on magnetic resonance imaging.</p>

Traumatic subluxation of the axis after hyperflexion injury of the cervical spine in children

　View Summary

<p>Six cases of children (four boys and two girls, mean age 11 years) who had traumatic subluxation of the axis (C2) were reviewed retrospectively. Initial radiographs demonstrated no detectable vertebral fracture in any of the children. However, a slight anterior subluxation of C2 was observed in three of the patients. Radiographs, taken at 1 month after injury in all but one patient, revealed a progression of the subluxation and a local kyphosis in all of the patients. Four of the children were treated conservatively with a cervical brace, and an improvement of both the kyphosis and the anterior slippage of C2 was obtained accompanied by an anteroposterior growth of the C3 vertebral body. The kyphosis of two of the patients became severe and, ultimately, these patients underwent fusion surgery. At the follow-up, none of the patients presented with any significant symptom. For the correct diagnosis of traumatic subluxation of C2, sequential radiographs to confirm the progression of subluxation and local kyphosis are mandatory. Conservative treatment rather than early surgical treatment may be chosen for this injury, because mild and moderate kyphosis can be corrected spontaneously by remodeling of the cervical spine.</p>
