To investigate the factors associated with the occurrence of Baastrup's disease (BA) in patients with lumbar degenerative diseases (LDDs). ⋯ BA is relatively common in patients with LDDs, and advanced age, severe intervertebral disc degeneration, and facet joint degeneration are its independent risk factors.

The brachial plexus is a network of nerves located between the neck and axilla, which receives input from C5-T1. Distally, the nerves and blood vessels that supply the arm and forearm form a medial neurovascular bundle. The purpose of this study was to illustrate that a peripheral nerve dissection via a 2 × 2 inch window would allow for identification and isolation of the major nerves and blood vessels that supply the arm and forearm. ⋯ Our study demonstrates that the majority of the neurovascular supply in the arm and forearm can be accessed through a 2 × 2 inch area in the medial arm. Although this "key window" may not be entirely utilized in the operative setting, our comprehensive didactic description of peripheral nerve dissection in the cadaver laboratory can help in safer identification of complex anatomy encountered during surgical procedures.

This study aimed to quantify the change in pressure on the cage during compression manipulation in lumbar interbody fusion. While the procedure involves applying compression between pedicle screws to press the cage against the endplate, the exact compression force remains elusive. We hypothesize that an intact facet joint might serve as a fulcrum, potentially reducing cage pressure. ⋯ Both normal and parallel compression maneuvers effectively increased the pressure on the cage, irrespective of the facet joint resection status. Compression manipulation consistently enhanced compressive force on the cage. However, when baseline pressure is low, the manipulation might not yield significant increases in compression force. This underlines the essential role of meticulous precompression preparation in enhancing surgical outcomes.

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. ⋯ Collaborative interventions are needed to address gaps in Nigeria's neurosurgical capacity. Investments in training, infrastructure, and funding are necessary for sustainable development and optimized outcomes.

Factors affecting outcomes of poor-grade subarachnoid hemorrhage.
Poor-grade subarachnoid hemorrhage (SAH) accounts for 20% of all SAH and is associated with poor outcomes. The first step in improving outcomes is to analyze the factors that contribute to poor outcomes. ⋯ Nonelderly patients who are not in grade V and Fisher group 4 should undergo aneurysm treatment as soon as possible because they are more likely to have a good outcome, whereas elderly patients in grade V and Fisher group 4 are unlikely to benefit from aneurysm treatment at present. The development of a treatment for early brain injury may be important to improve the outcomes of patients with poor-grade SAH.
