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.

Surgical treatment for spinal metastasis is still controversial. However, with the improvements in treatment for primary tumors, the survival rate of patients with spinal metastasis is enhanced. At the same time, surgical technique for spinal metastasis has also improved. ⋯ During the last decade, surgical treatment for spinal metastasis has increased in the United States. The overall in-hospital complication rate and hospital charges increased, whereas the in-hospital mortality rate and length of hospital stay remained stable.

Collagen hemostats have different characteristics depending on their properties and configuration. In vivo serial evaluation of local reactions because of placement of hemostats in the epidural space has not been reported. ⋯ Resorption of both hemostats was similar. In the MCH group, there was intense tissue inflammation around the hemostatic material, and MR images showed high signal intensity because of exudate accumulation in the epidural space. This indicated a strong foreign-body reaction to the MCH, thus demonstrating a difference in biocompatibility with the CCH.
