A methodological systematic review. ⋯ Given the plethora of previously hypothesized confounding risk factors for a spinal SSI, conduct of nonrandomized comparative therapeutic studies is strongly discouraged. On the other hand, methodological safeguards, including use of standardized definitions of putative confounders and outcomes, should be considered in more detail during the design phase of a randomized trial.

A single-center prospective case series. ⋯ Our analysis suggests that there are 2 distinct regions (lateral and medial) of shoulder height asymmetry. Medial differences reflected in trapezial prominence relate to deformity created by upward tilted proximal ribs and T1 tilt. Lateral differences in shoulder symmetry as reflected in the clavicle angle correlate weakly with radiographical measures. This suggests that correction of trapezial prominence may be more predictable compared with clavicle angulation after scoliosis surgery.

Computer modeling and simulations to analyze correction forces at the bone-screw interface in scoliosis instrumentation. ⋯ Bone-screw forces to achieve desired corrections can be minimized. However, EF are inevitable to secure the locking of all screws. Higher EF were associated with pedicle screws, with less degrees of freedom for connecting screw body to rod, that is, monoaxial followed by polyaxial and then by dorsoaxial screws.

A single-center retrospective study. ⋯ Patients undergoing 1 level MIS TLIF for degenerative conditions can overall expect a short LOS postoperatively. Multiple preoperative, intraoperative, and immediate postoperative factors can prolong the LOS in this group. This information should help the surgical team in optimizing their intraoperative patient management.

We describe an unusual cause of myelopathy with a discussion of similar cases previously reported in the literature. ⋯ Spinal gout should be considered in all patients presenting myelopathy and history of gout. When progressive neurological symptoms develop, surgical decompression can provide a satisfactory outcome.
