In order to avoid pedicle screw misplacement in posterior spinal deformity surgery, patient specific 3D‑printed guides can be used. An accuracy assessment of pedicle screw insertion can be obtained by superimposing CT-scan images from a preoperative plan over those of the postoperative result. The aim of this study is to report on the accuracy of drill guide assisted pedicle screw placement in thoracolumbar spinal deformity surgery by means of a superimpose CT-analysis. ⋯ The evaluated patient specific 3D-printed guide technology was demonstrated to constitute a safe and accurate tool for precise pedicle screw insertion in spinal deformity surgeries. Superimpose CT-analysis showed a 100% accuracy of pedicle screw placement without any violation of the pedicle wall or other relevant structures. We recommend a superimpose CT-analysis for the first consecutive patients when introducing new technologies into daily clinical practice, such as intraoperative imaging, navigation or robotics.

Review Meta Analysis
How helpful is the halo-gravity traction in severe spinal deformity patients?: A systematic review and meta-analysis.
This study sought to evaluate the complications and clinic outcome in radiographic parameters, pulmonary function, and nutritional status of halo-gravity traction (HGT) in treating severe spinal deformity. ⋯ Partial correction can be achieved by preoperative HGT, thereby reducing the difficulty of the operation and the risk of neurologic injury caused by excessive correction. Moreover, preoperative HGT can improve pulmonary function and nutritional status and, thus, increase patients' tolerance to surgery.

Review Case Reports Meta Analysis
Prognostic indicators of surgical outcome in painful foot drop: a systematic review and meta-analysis.
Foot drop is a relatively uncommon presentation of lumbar degenerative disease and there is currently a paucity of evidence on management and outcomes which is reflective of the lack of standardised treatment provided to patients. The purpose of this systematic review and meta-analysis is to determine the effectiveness of surgical management and the factors that predict surgical outcome. ⋯ This is the first systematic review and meta-analysis to explore the outcome and prognostic indicators of lumbar decompression for foot drop. Findings indicate that age, duration of foot drop weakness and MRC grade of foot drop prior to intervention were strong predictors of surgical outcome.
