A retrospective review of 10 consecutive patients with a noninflammatory retro-odontoid pseudotumor. ⋯ Retro-odontoid pseudotumors were not always associated with radiographic atlantoaxial instability. Our data indicate that extensive OALL and ankylosis of the adjacent segments are risk factors for the formation of the pseudotumor. Retro-odontoid pseudotumors may develop as an "adjacent segment disease" after altered biomechanics of the cervical spine, especially those in the adjacent segments. Posterior fusion was effective even in cases without radiographic atlantoaxial instability.

Comparative Study
A segmental partial laminectomy for cervical spondylotic myelopathy: anatomical basis and clinical outcome in comparison with expansive open-door laminoplasty.
A comparative study regarding the clinical outcome of the 2-different surgical procedures for patients with cervical spondylotic myelopathy (CSM). ⋯ A SPL, may therefore, be a useful and effective surgical procedure for cervical spondylotic myelopathy.

Case Reports
Favorable response to intrathecal, but not oral, baclofen of priapism in a patient with spinal cord injury.
Case report. ⋯ In the present case report, reduction of supraspinal control on the spinal cord may have induced an up-regulation of GABAB receptors, which are involved in penile tumescence. The trauma induced also liberation of penile reflexes with episodes of priapism. Normal full blood count and color duplex ultrasonography of the penis excluded a vascular genesis of priapism. This is the first report about the utility of intrathecal baclofen for the successful control of otherwise untreatable priapism in a patient with severe spinal spasticity. Hence, evaluation of intrathecal baclofen should be considered in patients suffering from severe and/or frequent priapism when oral baclofen and/or hormonal therapy are ineffective. The beneficial effect of intrathecal, but not oral baclofen, in our patient suggests a dose-dependent effect.
