A retrospective comparative study. ⋯ Old age, osteopenia, preoperative comorbidities, and severe global sagittal imbalance were found to be frequent in patients with proximal junctional fracture. In addition, marked correction of sagittal malalignment might be considered as a risk factor of upper instrumented vertebra collapse followed by adjacent vertebral subluxation, which occurred in the first 6 months after corrective surgery with the potential for causing severe neurologic deficit because of the severe local kyphotic deformity.
-
Retrospective matched cohort analysis. ⋯ Post-only adult scoliosis surgery achieved similar correction to A/P surgery while decreasing blood loss, operative time, length of stay, and avoiding additional anesthesia. Complications, radiographic, and clinical outcomes were similar at over 2-year follow-up.
-
Retrospective case-control study. ⋯ Cell saver use decreased allogeneic transfusion, particularly in surgeries >6 hours with estimated blood loss >30% of total blood volume. This study confirms the utility of routine cell saver use during PSF with segmental spinal instrumentation for idiopathic scoliosis.

Case Reports
Anteroposterior spondyloschisis of atlas with incurving of the posterior arch causing compressive myelopathy.
A case report of a patient with a combined anterior and posterior arch anomaly of atlas leading to compressive myelopathy. ⋯ We describe the association between compressive myelopathy and combined anteroposterior spondyloschisis of an atlas with incurving of the arch at defect site. Both computed tomography and magnetic resonance image were required to demonstrate the bony configuration and cord compression. And decompressive laminectomy of atlas was effective as a treatment for this compressive myelopathy caused by midline defect in the posterior atlantal arch with bony incurving.

Retrospective study. ⋯ Repeat surgical intervention following definitive spinal instrumented fusion for primary adult deformity performed at a single institution demonstrated a relatively low rate of 9.0%. The most common reasons for revision were predictable and included pseudarthrosis, proximal or distal curve progression, and infection.
