Does developmental canal stenosis influence surgical results of bilateral open-door laminoplasty for cervical spondylotic myelopathy?

Object: The purpose of this study was to investigate the prevalence of developmental canal stenosis in patients with cervical spondylotic myelopathy (CSM), and the correlation between surgical results and degree of developmental canal stenosis.

Methods: A total of 112 patients who eventually had surgical treatment for CSM were evaluated. Male patients whose sagittal spinal diameter was < 14 mm and females whose sagittal diameter was < 13 mm even at one level were classified as having developmental canal stenosis.

Cervical laminoplasty combined with muscle release in patients with athetoid cerebral palsy.

Study Design: A retrospective study comparing cervical laminoplasty with or without muscle release for the treatment of cervical myelopathy resulting from athetoid cerebral palsy.

Objective: To assess the effectiveness of muscle release in the treatment of athetoid cerebral palsy.

Summary Of Background Data: While anterior and/or posterior spinal fusion has been generally accepted as necessary in surgical treatment for cervical myelopathy due to athetoid cerebral palsy, several studies have shown relatively favorable results following laminoplasty.

Upper thoracic spinal cord injury without vertebral bony lesion: a report of two cases.

Study Design: Case report.

Objectives: To describe a rarely reported type of upper thoracic spinal cord injury without vertebral bony lesion in two cases with multiple trauma.

Summary Of Background Data: Because it is supported by the stiffness of the rib cage, the upper thoracic spine has greater stability than the cervical and lumbar regions, and thus its fracture or fracture dislocation is less frequent.
