Technical report. ⋯ VATS technique should be considered for a safe, efficacious, and durable CSF leak repair and as an alternative to open thoracotomy in the pediatric age group.

A study was performed using an axial loading device in healthy young subjects. ⋯ The compression device simulates the lumbar segmental alignment change from supine to standing posture in L1/2, L2/3, L3/4, and L4/5. However, in L5/S, axial loading using the DynaWell altered lumbar segmental alignment with a kyphotic change, while no significant difference was observed in this level between standing and supine positions. Awareness of these phenomena are essential for accurate interpretation of imaging results.

Prospective longitudinal study. ⋯ Our findings indicate that factors that allow us to identify patients at risk for poor recovery are age, dizziness, and initial evaluation of neck pain with VAS and cervical column functionality with NPH.

A human cadaveric biomechanical study comparing craniocervical fixation techniques. ⋯ Craniocervical stabilization using occipital condyle screws as the sole cephalad fixation point is biomechanically equivalent with regard to the modes tested (ROM and stiffness) to the standard occipital plate construct.

A case report and review of previous literature are presented. ⋯ We reported a rare characteristic anomaly of the laminae of the axis with hypoplasia of the posterior arch of atlas. A multiplane reconstruction of the computed tomography images was very necessary for treatment of this case. Possible causes of this anomaly may be the failure of ossification or fusion of the embryological term, whereas invagination of the osteophyte may be associated with the traction of the dense fibrous band during growth and development. Surgical removal of the laminae could result in a satisfactory outcome.
