OBJECTIVE Chondrodysplasia punctata (CDP), a rare skeletal dysplasia, can lead to cervical spine instability and deformity. However, an optimal neurosurgical intervention has yet to be established. Thus, a retrospective study was conducted to assess the efficacy of various surgical interventions for children with CDP. METHODS The authors retrospectively reviewed 9 cases of CDP in which cervical decompression with or without posterior fusion was performed between April 2007 and May 2016. Patient demographics, preoperative clinical conditions, radiographic findings, surgical procedures, and the postoperative course were analyzed in detail...

The craniovertebral junction (CVJ) has attracted more attention in pediatric medicine in recent years due to the progress in surgical technologies allowing a direct approach to the CVJ in children. The CVJ is the site of numerous pathologies, most originating in bone anomalies resulting from abnormal CVJ development. Before discussing the surgical approaches to CVJ, three points should be borne in mind: first, that developmental anatomy demonstrates age-dependent mechanisms and the pathophysiology of pediatric CVJ anomalies; second, that CT-based dynamic simulations have improved our knowledge of functional anatomy, enabling us to locate CVJ lesions with greater certainty; and third, understanding the complex structure of the pediatric CVJ also clarifies the surgical anatomy...

Prostate carcinoma presenting as symptomatic metastases to atlantoaxial spine is extremely rare. Spastic quadriparesis due to pathological fracture of odontoid as the only initial manifestation without symptoms of primary malignancy is rarer still. We report a 64-year-old male who presented with progressive spastic quadriparesis along with urinary retention of 3 weeks duration. Computed tomography and magnetic resonance imaging cervical spine and craniovertebral junction showed type III pathological fracture of odontoid with anterior translation of C1 with spinal cord compression...

REVIEW
A A Zuev, G V Kostenko
Syringomyelia (SM) develops due to the disturbance of cerebrospinal fluid dynamics, spinal fixation or a spinal tumor. The disturbance of cerebrospinal fluid dynamics in the area of the foramen magnum leads to the progression of SM in Chiari 1 malformation (CM1). CM1 is the most prevalent pathology of craniovertebral junction associated with SM. The prevalence of CM1 varies from 3 to 8 per 100 000 population but SM is diagnosed in 65% of patients with CM1. Clinical symptoms of CM1 and SM include pain in the occipital area, gait disturbances due to sensitive ataxia, dissociated sensory disorders, dysphagia, paresis of the extremities...
