Lumbar Pedicle Dimensions Using CT Scan in Adults of South-Eastern Nigeria as Related to Transpedicular Fixation.

Background: Transpedicular fixation depends on accuracy of the entry points, angle of insertion and pedicular isthmus width for adequate screw insertion. Preoperative measurements of pedicle dimensions reduce the chances of failure during insertion. These pedicle dimensions (transverse diameter, longitudinal diameter, and maximum length of purchase [MLP]) vary with sex and race.

Assessment of childhood intracranial pressure: a comparative study of transcranial Doppler ultrasound indices and findings at ventriculoperitoneal shunt.

Purpose: This study compares transcranial Doppler (TCD) Pulsatility Index (PI) and Resistivity Index (RI) with intra-operative CSF opening pressure measured by manometric technique during ventriculoperitoneal (V-P) shunt in children with hydrocephalus.

Methods: It was a prospective, hospital-based study performed among patients diagnosed with hydrocephalus. Patients had TCD ultrasonography before V-P shunt.

A Geospatial Analysis of the Availability, Distribution, and Accessibility of Neurosurgical Facilities, Workforce, and Infrastructure in Nigeria; and Projection Towards 2050.

Objective: There has been a modest but progressive increase in the neurosurgical workforce, training, and service delivery in Nigeria in the last 2 decades. However, these resources are unevenly distributed. This study aimed to quantitatively assess the availability and distribution of neurosurgical resources in Nigeria while projecting the needed workforce capacity up to 2050.

Correlation of the transorbital ultrasonographic optic nerve sheath diameter with intracranial pressure measured intraoperatively in infants with hydrocephalus.

Objective: Hydrocephalus is a highly significant global public health concern. In infants, it may be associated with a potentially deleterious increase in intracranial pressure (ICP). Currently, the gold standard for accurate monitoring of ICP is an intraventricular ICP monitor, but this method is invasive and expensive.

The Status of Specialist Neurosurgical Training in Nigeria: A Survey of Practitioners, Trainers, and Trainees.

Objective: Despite the well-known neurosurgical workforce deficit in Sub-Saharan Africa, there remains a low number of neurosurgical training programs in Nigeria. This study sought to reassess the current status of specialist neurosurgical training in the country.

Methods: An electronic survey was distributed to all consultant neurosurgeons and neurosurgery residents in Nigeria.
