Pineal lesions are common causes of dorsal midbrain syndrome and typically require surgical intervention in symptomatic patients. We describe a unique case of spontaneous resolution of dorsal midbrain syndrome resulting from a pineal gland cyst. ⋯ Dorsal midbrain syndrome resulting from a pineal cyst may spontaneously improve even without a significant change in lesion size. This suggests that observation may be an appropriate initial management strategy.

Enthusiasm for research and teaching are often the main reasons neurosurgical residents choose academic careers, and subspecialty choice usually stems from an interest in that particular field. However, recent salary data bring to light a work relative value unit-related trend in American academic neurosurgeon salaries, one that is similar to private practice, where compensation is strongly correlated with clinical productivity. ⋯ For example, functional and pediatric specialists earn significantly lower salaries on average compared with their spine and endovascular colleagues. These trends have important implications both for neurosurgical trainees and for institutions in the United States.

The aim of this study was to evaluate regional variations in the management, complications, and total cost of admission for adolescent idiopathic scoliosis (AIS) treated by elective posterior spinal surgery (PSF, ≥4 levels). ⋯ Our study suggests that there may be regional variations in health care resource utilization in AIS patients undergoing multilevel posterior spinal fusions. Further study is warranted to determine the specific factors contributing to disparities in regional outcomes.

Heterotopic ossification (HO) and anterior bone loss (ABL) are 2 complications in cervical disc replacement (CDR), which have impacts on the clinical outcomes. Physiologically, bone formation (HO) and bone loss are 2 sides of bone remodeling. However, clinically, some patients experienced anterior HO (AHO) after CDR, whereas other patients experienced ABL. Is there any factor in determining the fate of the vertebral bone in the anterior region? Is ABL the opposite of AHO? This study aims to answer these questions. ⋯ The differences in the disc angle showed the role of mechanical load in the anterior bone remodeling. Combined the results with the basic concepts of bone remodeling, ABL may be the opposite of AHO.

To assess the role of the difference between the proximal junctional angle (PJA) and rod contouring angle (RCA) (PJA-RCA) in the development of postoperative proximal junctional angle (PJK) in Lenke I and II adolescent idiopathic scoliosis (AIS) patients. ⋯ Large postoperative PJA-RCA and decreased TK are risk factors for PJK in Lenke I and II AIS patients, especially those with PJA-RCA greater than 5°, and the occurrence of PJK should be highly considered.
