Intraoperative computed tomography and navigation (iCT-Nav) is increasingly used to aid spinal instrumentation. We aimed to document the accuracy and revision rate of pedicle screw placement across many screws placed using iCT-Nav. We also assess patient-level factors predictive of high-grade pedicle breach. ⋯ iCT-Nav with postinstrumentation intraoperative imaging is associated with a reduced need for costly postoperative return to the operating room for screw revision. In comparison with studies of navigation without iCT where 1.5%-1.7% of patients returned for a second surgery, we report 0 revision surgeries due to screw malpositioning.

Intraoperative navigation during spine surgery improves pedicle screw placement accuracy. However, limited studies have correlated the use of navigation with clinical factors, including operative time and safety. In the present study, we compared the complications and reoperations between surgeries with and without navigation. ⋯ Navigated surgery patients experienced longer operations owing to a combination of the time required for navigation, more multilevel procedures, and a larger comorbidity burden, without differences in the incidence of infection. Fewer complications and wound washouts were required for navigated lumbar surgery owing to a greater proportion percentage of minimally invasive cases. The combined use of navigation and minimally invasive surgery might benefit patients with the proper indications.

Adjuvant radiotherapy (RT) can help achieve local control (LC) and reduce hormonal overexpression for pituitary adenomas (PAs). Prior reports involved Gamma Knife or older linear accelerator (LINAC) techniques. The aim of this study was to report long-term outcomes for modern LINAC RT. ⋯ Modern LINAC RT for patients with PAs was safe and effective for hormonal control and LC. No difference in LC was noted for functional versus nonfunctional tumors, possibly owing to higher total dose and daily image guidance.

To explore the feasibility of using a modified power-on programming method in deep brain stimulation (DBS) for Parkinson disease (PD). ⋯ The modified power-on programming method can achieve a similar clinical effect to the traditional method, with the advantage of more efficiency.

We compared the patient-reported outcomes (PROs), minimal clinically important difference (MCID) achievement, and perceived postoperative satisfaction after minimally invasive lumbar decompression of patients stratified by self-identified gender. ⋯ Despite the similar preoperative baseline values, postoperative improvement, and clinical outcomes, our results suggest that the self-identified male patients will have poorer short-term satisfaction for disability, leg pain, back pain, and lifting versus patients in the self-identified female group. Self-identified gender might influence patient satisfaction and could be attributed to differing preoperative expectations at baseline for short-term recovery.
