In Vitro Biomechanical and Fluoroscopic Study of a Continuously Expandable Interbody Spacer Concerning Its Role in Insertion Force and Segmental Kinematics.
CONCLUSIONS: Results from the three study arms reveal the potential use of expandable spacers. During implant insertion, CESs provided similar stability, required less insertion force, and significantly reduced over-distraction of the annulus compared with SS.

Evaluating Pedicle-Screw Instrumentation Using Decision-Tree Analysis Based on Pullout Strength.
CONCLUSIONS: The random forest regression model was used to build a pullout-strength predictor and decision tree. The model was able to predict the holding power of a pedicle screw for any combination of density, insertion depth, and insertion angle for the chosen range. The decision-tree model can be applied in patient-specific surgical planning and a decision-support system for spine-fusion surgery. PMID: 30060368 [PubMed] (Source: Asian Spine Journal)

Effect of Different Types of Upper Instrumented Vertebrae Instruments on Proximal Junctional Kyphosis Following Adult Spinal Deformity Surgery: Pedicle Screw versus Transverse Process Hook.
CONCLUSIONS: Our results show that using TPH as a UIV implant may not prevent PJK; however, using TPH as the UIV anchor may prevent vertebral collapse if cases of UIV fracture. The increased risk of UIV fracture collapse in the PS group may be a result of a higher mechanical load on UIV when using PS. PMID: 30060369 [PubMed] (Source: Asian Spine Journal)

Intraoperative Halo-Femoral Traction in Surgical Treatment of Adolescent Idiopathic Scoliosis Curves between 70 ° and 90°: Is It Effective?
CONCLUSIONS: Intraoperative HFT is an effective and reliable method for the management of scoliosis curves between 70° and 90°. The most significant advantages of the method are avoidance of the morbidities related to anterior surgery, osteotomy, or vertebral column resection; its contribution in helping achieve adequate reduction and optimum balance by the gradually increased corrective force, lack of any need for extreme correction force during instrumentation; and the high correction rates achieved.

Role of Whole-Spine Screening Magnetic Resonance Imaging Using Short Tau Inversion Recovery or Fat-Suppressed T2 Fast Spin Echo Sequences for Detecting Noncontiguous Multiple-Level Spinal Tuberculosis.
CONCLUSIONS: Tubercular spondylitis may affect the spine at multiple noncontiguous sites with the majority of additional affected sites remaining asymptomatic. Routine whole-spine MRI using all recommended sequences is not cost-effective and hence not feasible. Therefore, we recommend whole-spine screening using STIR or fat-suppressed T2W FSE sequences in all patients with suspected spinal TB. This screening is cost-effective compared with full-protocol MRI and detects additional cases of NMLST over conventional practice. PMID: 30060377 [PubMed] (Source: Asian Spine Journal)

Comparison of Three Different Options for C7 Posterior Vertebral Anchor in the Indian Population-Lateral Mass, Pedicle, and Lamina: A Computed Tomography-Based Morphometric Analysis.
CONCLUSIONS: Based on our CT-guided morphometric analysis, 92% and 48% of Indian patients could accommodate at least 10- and 12-mm long lateral mass screws, and 58% of pedicles and 37% of laminae could accommodate 3.5-mm screws. Thus, lateral mass screws (between 10- and 12-mm long) seem to be the safest feasible option for C7 fixation. In case of the need for an alternative mode of stabilization (pedicle or intralaminar screw), particularly in female patients, careful preoperative planning with a CT scan is of utmost importance.

While surgical decompression remains the standard of care, choosing an optimal management strategy is usually guided by a set of clinical, radiological, and measurement indices. However, to date, there is a major uncertainty and discrepancy regarding the methodology used. There is also inconsistent adoption of outcome measures across studies, which may result in huge limitations i...

CONCLUSIONS: The presence of LSTV was associated with an increased prevalence of LBP. This association was probably due to the confounding effect of OSD. The level of occupational physical activity was not associated with LSTV-related LBP. We speculate that advanced age and female sex caused the spurious association of LSTV with LBP in our study, rendering LSTV-related LBP controversial in published literature.
