Promoting minorities within medical specialties has been postulated to be crucial to patient care and recruitment of diverse candidates. This concept has been suspected but not formally studied in the minority of women faculty and trainees in neurosurgery. We aimed to quantitatively investigate the postulated correlation relative to female representation in neurosurgery. ⋯ This study of current female representation in neurosurgery revealed a previously undocumented positive correlation between percentages of female faculty and female trainees. These data suggest a modifiable barrier to female entry into neurosurgical residency programs.

Screw loosening is a common complication of pedicle screw internal fixation surgery. This study aimed to investigate whether the application of a porous scaffold structure can increase the contact area between screws and bone tissue by comparing the bone ingrowth and screw-bone interface of porous scaffold core pedicle screws (PSCPSs) and hollow lateral hole pedicle screws (HLHPSs) in the lumbar spine of Bama pigs. ⋯ Compared with HLHPSs, PSCPSs possessing a porous scaffold core could promote bone ingrowth and osseointegration, resulting in an effective enhancement of the combined area of the screw-bone interface.

Traumatic brain injury (TBI) significantly contributes to morbidity rates. While computed tomography (CT) scoring systems have been recognized as predictive factors for TBI outcomes, their association with shunt dependency in patients undergoing decompressive craniectomy (DC) has not been investigated. This study aimed to evaluate the predictive utility of CT scoring systems concerning shunt-dependent hydrocephalus in patients post-DC for TBI. ⋯ The CT scoring systems proved insufficient for predicting shunt-dependent hydrocephalus following DC for TBI. However, our observations underscore a significant correlation between post-traumatic shunt dependency after DC and an increased incidence of unfavorable outcomes during long-term follow-up.

Pineal tumors are rare, and the pineal region is a challenging surgical location for neurosurgeons. The present study aimed to investigate the effects of microsurgical management in patients with pineal region tumors and explore probable factors associated with preoperative hydrocephalus, postoperative hydrocephalus remission, and prolonged hospital length of stay (LoS). ⋯ Microsurgical resection of pineal tumors yielded favorable long-term outcomes. Patients with a lower KPS score, younger age, and larger maximum tumor diameters were more vulnerable to preoperative hydrocephalus and prolonged LoS. Patients with a lower KPS score or larger tumor diameter were likely to achieve significant remission of hydrocephalus after tumor resection.
