Comparative StudyComparison of disc and vertebral wedging between patients with adolescent idiopathic scoliosis and Chiari malformation-associated scoliosis.
A comparative study. ⋯ The relative wedging of intervertebral disc and vertebrae with AIS patients is similar to that of scoliosis with known cause (CMS). The wedging of discs and vertebrae in AIS patients may be an adaptive change secondary to some extravertebral factors.

Feasibility of C2 translaminar screw as an alternative or salvage of C2 pedicle screws in atlantoaxial instability.
A retrospective outcome study. ⋯ C2 translaminar screws provide surgeons with an expanded option for posterior fusion in high cervical lesions. This technique is safe and easy to adopt with a favorable rate of successful fusion. We believe that preoperative planning using computed tomographic scan is mandatory and use of an additional connector may reduce the stress and strain of the screws.
