Practice consolidation in healthcare has widespread consequences for providers and patients. Although many studies describe this phenomenon in various medical specialties, no such analysis has been performed in neurosurgery specifically. The goal of this study was to assess the trends in the size of U.S. neurosurgery practices over a 5-year period. ⋯ This study shows that over the past 5 years, a substantial trend toward increasing practice sizes has evolved. The effect of the differences in practice size should be examined to determine the large-scale impacts on patient care, payment models, and healthcare access, in addition to neurosurgeon compensation, and satisfaction.

The preoperative assessment of C2 morphology is important for safe instrumentation. Sclerotic changes are often seen in C2 pedicles. Evaluating the diameter measurements solely might not accurately assess the safety of screw insertion. We have proposed a novel grading system of the C2 pedicle that includes sclerosis and evaluated the predictive value of this grading system with the surgeon's safety evaluation. ⋯ We have introduced a novel tool to evaluate the safety of C2 pedicle screw placement. Our results suggest that our pedicle width-sclerosis grading system is reproducible and predicts the surgeon's assessment of safe screw placement better than C2 pedicle diametrical measurements alone.

A mainstay of treatment for symptomatic adjacent segment disease (ASD) has consisted of revision with posterior decompression and fusion. This carries significant morbidity and can be technically difficult. An alternative is stand-alone lateral lumbar interbody fusion (LLIF), which may avoid complications associated with revision surgery. We describe the largest cohort of patients treated with LLIF for ASD to our knowledge. ⋯ To our knowledge, this is the largest cohort study of patients to date evaluating stand-alone LLIF for ASD. Our patient outcomes show it is safe and effective with low risk of morbidity.

Collision of craniopharyngioma and pituitary adenoma: comprehensive review of an extremely rare sellar condition.
The collision of pituitary adenoma and craniopharyngioma is extremely rare and thus there remains a paucity of data. ⋯ Most craniopharyngiomas were adamantinomatous. There are 2 types of collisions: separated and admixed. Tumor control, overall survival, and endocrinologic remission are more challenging to achieve than for solitary tumors, but gross total resection of both tumors is important for satisfactory tumor control.

A novel anterior cervical X-shape-corpectomy and fusion for cervical spinal stenosis at C4-6 level: a technical note.
Anterior cervical corpectomy and fusion (ACCF) is employed in patients with localized cervical spinal stenosis (CSS). However, there are some disadvantages such as subsidence of the titanium mesh cage, slow fusion rates, breakage of the plate and screws, and donor-site complications. For patients with small posterior osteophytes, ossified or hypertrophy of the posterior longitudinal ligaments or ligamentum flavum, the range of decompression from the classic anterior cervical discectomy and fusion (ACDF) cannot meet the clinical requirements. However, employing ACCF is controversial. Therefore, it is necessary to seek a novel, safe and effective surgery that can combine the strengths of ACDF and ACCF. Our objective was to describe a novel anterior approach cervical surgery and investigate its clinical outcomes on segmental CSS at the C4-C6 levels 6 months postoperatively. ⋯ ACXF may be a safe and effective procedure for segmental CSS and an alternative for ACCF, as it has a wide operative field of view, sufficient decompression range, excellent transverse vertebral bony fusion, less internal fixation-related complications, and graft subsidence and no donor-site complications.
