Perioperative visual loss (POVL) is a rare but devastating complication that may follow spinal surgeries. The incidence of POVL after spinal fusion is not well characterized during the past decade. ⋯ Our findings demonstrated an overall POVL incidence of 1.9 events per 10,000 spinal fusions. Patients undergoing thoracic fusion for deformity correction accounted for the majority of cases of POVL. Despite being a rare complication after spinal fusion, POVL is an adverse event that may not be entirely preventable. Patients undergoing long-segment fusions for deformity and those with certain risk factors should be counseled regarding the risks of POVL.

Traditionally, the "dynamic" and "static" types of spondylolisthesis have been lumped into a single group in the literature. The goal of this study was to define the radiographic characteristics of "dynamic" and "static" spondylolisthesis with the use of magnetic resonance imaging (MRI) and flexion/extension radiographs. ⋯ The presence of FF and/or ISF is associated with instability greater than 3 mm in flexion/extension radiographs.

Minimally invasive transforaminal lumbar fusion (MIS-TLIF) has demonstrated efficacy in the treatment of lumbar degenerative diseases. The reported incidence of perioperative complications associated with MIS-TLIF surgery is highly variable. Studies concerning perioperative complications in broad patient populations are quite rare. This study analyzes a retrospectively collected database of patients who underwent an MIS-TLIF surgery at a single center. ⋯ Minimally invasive transforaminal lumbar fusion has gained popularity as a procedure for the treatment of lumbar instability or spondylolisthesis, with similar complications as in the open surgery. Transient sensory disturbance was the most common complication in this series.

Surgical treatment of degenerative disc disease remains a controversial subject. Lumbar fusion has been associated with a potential risk of segmental junctional disease and sagittal balance misalignment. Motion preservation devices have been developed as an alternative to fusion. The LP-ESP disc is a one-piece deformable device achieving 6 df, including shock absorption and elastic return. This is the first clinical report on its use. ⋯ Results from the 2-year follow-up indicate that LP-ESP prosthesis recreates lumbar spine function similar to that of the healthy disc in terms of ROM, quality of movement, effect on sagittal balance, and absence of modification in the kinematics of the upper adjacent level.

Little is known about the psychological status in patients with ankylosing spondylitis (AS) before and after correction of fixed sagittal imbalance. ⋯ The scores of disease status, general health, and psychological status were improved significantly after correction of kyphotic deformity. And the correction of sagittal imbalance was correlated significantly with anxiety and depression.
