Microsurgical Resection of a Pineal Cyst via a Paramedian Supracerebellar Infratentorial Approach.
Pineal cysts are typically detected in around 1.3% to 4.3% of patients during routine magnetic resonance imaging (MRI) scans.1,2 The vast majority of pineal cysts are benign, asymptomatic, and typically do not necessitate surgical intervention. Large pineal cysts are known to cause hydrocephalus with its associated symptoms and thus can require in rare cases surgical resection. Even in the absence of hydrocephalus, selected patients with large pineal cysts causing headaches and visual disturbances can find relief after surgical resection.3,4 The supracerebellar infratentorial (SCIT) approach is widely used and represents an extraparenchymatous approach through a natural corridor to the pineal region.5 Performing this approach in a semisitting position allows for an optimal retraction of the cerebellum by gravity. ⋯ A subsequent MRI revealed enlargement of the pineal cyst, leading to the indication for surgical resection. The surgery was performed mainly under the operating microscope with endoscopic visualization in suitable situations as our small approach restricts bimanual dissection with an endoscope. In our experience, this approach provides a versatile and minimally invasive access to the pineal region, making it optimally suitable for pineal cysts requiring surgical resection.

Although dual-energy X-ray absorptiometry is still the gold standard for diagnosing osteoporosis, it can lead to inaccurate bone mineral density measurements due to lumbar degeneration and scoliosis. Many researchers have investigated diagnostic methods for osteoporosis in patients with degenerative lumbar scoliosis (DLS). This study aimed to investigate the differences between conventional vertebral bone quality (VBQ) scores and modified VBQ scores in patients with DLS and the influence of lumbar scoliosis on VBQ scores. ⋯ Different modified VBQ scores can be used as supplementary methods for diagnosing osteoporosis in patients with DLS. Lumbar scoliosis may not significantly affect the VBQ score.

This was a single-institutional retrospective cohort study. ⋯ The online wound-related risk calculator was found to accurately predict wound infections but not wound reoperations within our metastatic spine surgery cohort. We suggest that the model may be clinically useful despite underlying population differences, but further work must be done to generate and validate accurate prediction tools.

Cervical spine procedures represent a major proportion of all spine surgery. Mitigating the revision rate following cervical procedures requires careful patient selection. While complication risk has successfully been predicted, revision risk has proven more challenging. This is likely due to the absence of granular variables in claims databases. The objective of this study was to develop a state-of-the-art model of revision prediction of cervical spine surgery using laboratory and operative variables. ⋯ Our deep learning approach successfully predicted 3-month revision outcomes from demographic variables, standard laboratory values, and operative variables in a cervical spine surgery cohort. This work used standard laboratory values and operative codes as meaningful predictive variables for revision outcome prediction. The increased performance on certain procedures evidences the need for careful development and validation of one-size-fits-all risk scores for spine procedures.

The aging global population presents an increasing challenge for spine surgeons. Advancements in spine surgery, including minimally invasive techniques, have broadened treatment options, potentially benefiting older patients. This study aims to explore the clinical outcomes of spine surgery in septuagenarians and octogenarians. ⋯ This case series demonstrates that septuagenarians and octogenarians can achieve favorable clinical outcomes with elective spine surgery. Spine surgeons should be well-versed in the clinical and surgical care of older adults, providing optimal management that considers their increased comorbidity burden and heightened fragility.
