Prospective study with 12-month follow-up. ⋯ Overall, greater back pain relative to LP at baseline was associated with a significantly worse outcome after decompression. This finding seems intuitive, but has rarely been quantified in the many predictor studies conducted to date. Consideration of relative LBP and LP scores may assist in clinical decision-making and in establishing realistic patient expectations.

A case report about transoral osteosynthesis C1 as a function-preserving option in the treatment of bipartite atlas deformity. ⋯ We described a rare association of an anterior arch midline defect, posterior arch midline aplasia. The natural history of patients with bipartite atlas deformity suggests that these people have a potentially precarious existence. Transoral osteosynthesis of the anterior ring and the lateral masses of C1 is a new technique that allows maintenance of rotatory mobility in the C1-C2 joint and restoration of congruency in the atlanto-occipital and atlantoaxial joints.

It is a retrospective study of 52 neuromuscular scoliosis patients with cerebral palsy (CP). ⋯ We reported satisfactory coronal and sagittal correction with posterior-only pedicle screw fixation without higher complication rate in CP patients. Further long-term study is recommended to evaluate the success of pedicle screw in this population.

An anatomic study of lumbar facet anatomy for transfacet fixation. ⋯ Ipsilateral transfacet fixation can be successfully performed in the L3-S1 segments by using the inferior end plate and medial pedicle wall of the superiorly instrumented level as anatomic landmarks in conjunction with axial and sagittal angles of insertion.
