Selective dorsal rhizotomy (SDR) has been a well-established neurosurgical treatment option for ambulatory children with spastic diplegic cerebral palsy to reduce spasticity. Outcomes for SDR for spastic lower extremity hemiparesis has been less well described. In our experience, hemi-SDR has been an excellent intervention for children with suboptimal spasticity control despite maximizing pharmacologic and chemodenervation treatments. ⋯ He also demonstrated a step length ratio closer to 1 (0.89) showing a more equal step length bilaterally and improved weight acceptance on the affected side. There were no changes observed on the left upper extremity. This positive outcome on spasticity control and function supports the need for further prospective studies for hemi-SDR as a treatment option for children with spastic hemiparesis.

Predatory journals (PJs) publish research with little to no rigorous peer review in exchange for money. It is unclear what proportion of researchers is vulnerable to PJs and which factors are associated with vulnerability. The aim of this study was to evaluate the vulnerability of African neurosurgery researchers to PJs and identify their correlates. ⋯ Young African neurosurgery researchers are vulnerable to PJs primarily because they are not familiar with the concept of PJs or how to identify them.

Studies investigating seasonality as a risk factor for surgical site infections (SSIs) after spine surgery show mixed results. This study used national data to analyze seasonal effects on spine surgery SSIs. ⋯ PCF, PLF, and lumbar laminectomy performed during the warm season had significantly higher odds of SSI, especially postdischarge SSIs. Reoperation rates for wound management were significantly increased during the warm season for PLFs. Identifying seasonal causes merits further investigation and may influence surgeon scheduling and expectations.

Primary central nervous system lymphoma is a rare form of extranodal non-Hodgkin lymphoma. Few cases of primary central nervous system lymphoma involving bone and subcutaneous tissue invasion have been reported. ⋯ Craniotomy and tumor removal were performed. Operative findings showed a posterior occipital soft tumor whose cells had invaded the skull and subcutaneous tissue.

A 32-year-old woman presented with chronically progressive spastic quadriparesis. Detailed clinicoradiological evaluation led to the diagnosis of irreducible atlantoaxial dislocation and basilar invagination, with associated "kissing" carotids and an anomalous right vertebral artery (VA). Both internal carotid arteries had an abnormally tortuous course, "kissing" retropharyngeally at the level of C1-C2. ⋯ Despite the deformed joints and the possibility of injuring the anomalous right VA during C2-C3 instrumentation, a tailored posterior-only approach was used to circumvent the arterial fence created by both vascular anomalies. The patient underwent bilateral C1-C2 joint opening and left C1-C2 joint spacer placement, followed by bilateral occipito-C3-C4 fixation. This is possibly the first reported case of a complex craniovertebral junction anomaly associated with both kissing carotids and a C3 segmental VA.
