Transforaminal lumbar interbody fusion (TLIF) is an effective treatment of upper lumbar intervertebral disk herniation. However, its clinical efficacy for adjacent segment disk degeneration (ASDD) remains undefined. Therefore, the biomechanical evaluation of ASDD caused by TLIF after pedicle screw fixation (PSF) was explored via a 3-dimensional (3D) finite element analysis. ⋯ This study provides evidence that TLIF may aggravate ASDD after PSF. Furthermore, the findings provided in this report represent the theoretic basis for the clinical analysis of ASDD caused by TLIF after PSF.

Transverse process fractures in trauma patients frequently are diagnosed using computed tomography and result in severe pain and limitation of motion. However, there is no accepted standard of care. Thus, these fractures can be treated with excessive measures or inadequately treated. In this study, diagnosis and treatment of transverse process fractures are examined. ⋯ Transverse process fractures can be treated quickly and effectively with the recommended protocol after excluding any accompanying organ injuries or other spinal injuries. Transverse process fractures most often occur during backward falls or blows to the back, commonly low-energy injuries. This trauma mechanism can be described as a "coronal injury of the spine."

The factors associated with initial and delayed remission after growth hormone (GH)-secreting pituitary adenoma excision have not been completely elucidated. ⋯ A lower Knosp grade of 0-2 and lower postoperative day 1 GH level were independent predictors of surgical remission. The baseline IGF-1 and PO3M IGF-1 indexes might predict for initial and delayed remission, respectively.

This study aimed to analyze the efficacy of oblique lumbar interbody fusion (OLIF) in the treatment of degenerative lumbar disease. ⋯ OLIF is a safe and effective minimally invasive procedure for the treatment of degenerative lumbar disease.

This study aimed to evaluate the efficacy and safety of stereotactic aspiration of necrotic brain tissue for treating malignant middle cerebral artery infarction (MMI) in patients older than 60 years of age. ⋯ Our results suggest the stereotactic aspiration of necrotic brain tissue is an effective and safe method in patients with MMI who are over 60 years of age.
