To determine the effect of planned two-stage surgery using lateral lumbar interbody fusion (LLIF) on the perioperative complication rate following corrective fusion surgery in patients with kyphoscoliosis. ⋯ The complication rate for planned two-stage surgery was similar to that of previous posterior-only single-stage surgery. However, early reoperation was less common, and the degree of spinal correction and clinical results were significantly better after two-stage surgery.

Meeting the information needs of patients adequately is of high importance in informed consent consultations in surgery. However, information needs often remain unmet in the informed consent consultation. The aim of this study was to assess anxiety and pain in relation to the patients' information needs fulfillment perioperatively. ⋯ Patients' anxiety was associated with (un)fulfilled information needs. Meeting information needs should be optimized in the process of surgeon-patient communication. Adapting the information to the patients' anxiety levels seem to be an effective way to reduce anxiety.

Ossification of the posterior longitudinal ligament (OPLL) causes serious problems, such as myelopathy and acute spinal cord injury. The early and accurate diagnosis of OPLL would hence prevent the miserable prognoses. Plain lateral radiography is an essential method for the evaluation of OPLL. ⋯ An algorithm trained by an RNN could make binary classification of OPLL on cervical lateral X-ray images. RNN may hence be useful as a screening tool to assist physicians in identifying patients with OPLL in future setting. To achieve accurate identification of OPLL patients clinically, RNN has to be trained with other cause of myelopathy.

This study's objective was to assess biomechanical parameters across fused and contralateral sacroiliac joints (SIJs) and implants during all spinal motions for both sexes. Various SIJ implant devices on the market are used in minimally invasive surgeries. These implants are placed across the joint using different surgical approaches. The biomechanical effects of fusion surgical techniques in males and females have not been studied. ⋯ Implants exhibited higher stresses in the female model compared to the male model. However, chances of SIJ implant failure in the female patients are still minimal, based on the calculated factor of safety which is still very high. Both lateral and posterior surgical approaches were effective in both sexes; however, the lateral approach may provide a better biomechanical response, especially for females. Moreover, implant design characteristics did not make a difference in the implants' biomechanical performance. SIJ stabilization was primarily provided by the implants which were the farthest from the sacrum rotation center.

Review Meta Analysis
Lack of association between TNF polymorphism and ankylosing spondylitis susceptibility in HLA-B27-positive population: a meta-analysis.
Human leukocyte antigen (HLA)-B27 plays a crucial role in the pathogenesis of AS. TNF polymorphisms have been reported to be associated with AS susceptibility, but the results of these previous studies have been inconsistent. The aim of this study was to explore whether TNF polymorphism is associated with AS susceptibility in HLA-27-positive population. ⋯ There was no association of the TNF polymorphisms with AS in the HLA-B27-positive AS group and HLA-B27-positive control group. Polymorphisms of TNF-238, -308, -857, -1031, -863 were associated with AS susceptibility in the HLA-B27-positive AS patients and random control population. Other gene SNPs except TNF may play an important role in AS susceptibility in HLA-B27-positive population.
