Although chronic subdural hematoma (CSDH) is generally benign, long-term survival (LTS) after CSDH is poor in a significant subgroup. This dichotomy has been compared to fractured neck of femur. However, although early postoperative mortality (within 30 days of CSDH) is well recorded with CSDH and similar to fractured neck of femur (4%-8%), scant accurate data exist regarding early postoperative morbidity (POMB). POMB, which prolongs length of stay (LOS) after major nonneurosurgery, is associated with decreased LTS. One recent CSDH study suggested a POMB standard of 10% i.e., notably less than with fractured neck of femur (45%). ⋯ POMB was frequently disabling, mostly neurologic, and as frequent and diverse as with fractured neck of femur. POMB was significantly correlated with LOS and discharge modified Rankin Scale score. Surprisingly, POSSUM, ACS-NSQIP, and ASA grades were not predictive and would not aid consent. Simple parameters (age, Glasgow Coma Scale, Markwalder grade, hypertension, and/or ≥1 other comorbidity) were instead predictive. Longitudinal follow-up will determine whether POMB affects LTS. CSDH, like fractured neck of femur, is distinct.

We report a patient with primary central nervous system mixed malignant germ cell tumor (GCT) who presented with recurrent malignant germinomatous infiltration of the retina. ⋯ Loco-regional extension of suprasellar GCT to the optic nerve is not uncommon; however, to the best of our knowledge, infiltration of the tumor into the retina is not reported in the literature. Early detection of optic pathway involvement and proper delineation of the irradiation field may prevent GCT infiltration of the retina with subsequent vision loss.

To assess the relationship between the ratio of C2-C7 Cobb angle to T1 slope (CL/T1S) and cervical alignment changes after laminoplasty. ⋯ The cervical alignment was kept well in the mid-range CL/T1S ratio group after laminoplasty. Patients with a high CL/T1S ratio were more likely to present with kyphotic alignment changes. Patients with a low CL/T1S ratio were more likely to have postoperative kyphosis.

To report our experience of the management of 60 patients with craniopharyngioma with endoscopic endonasal surgery (EES) and evaluate the feasibility and safety of EES for craniopharyngiomas. ⋯ EES can provide surgeons with excellent exposure and can achieve a high extent of removal of most craniopharyngiomas, even those with intraventricular extensions, In our view, vascularized pedicled septal flaps and in situ bony flaps were used in skull base reconstruction.

To compare the impact of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) with open posterior lumbar interbody fusion (PLIF) on sagittal lumbar-pelvic radiographic parameters for degenerative spondylolisthesis (DS). ⋯ For low-grade DS, open PLIF has a higher rate of slip reduction compared to MIS-TLIF, and significantly reduces LASD, therefore, it is more conducive to improving lumbar sagittal balance.
