Patients with brachial plexus birth injuries (BPBIs) are at risk for limitations in shoulder external rotation. The role of lower trapezius tendon transfer to restore shoulder external rotation in this population has not been well characterized. This study aimed to evaluate the utility of lower trapezius tendon transfer for restoration of external rotation in a subset of pediatric patients. ⋯ Lower trapezius tendon transfer for BPBI showed a statistically significant but unlikely clinically meaningful improvement in external rotation with a high rate of reoperation.

The aim of this study was to assess the diagnostic yield of follow-up investigations in aneurysm-negative subarachnoid hemorrhage (SAH) patients. ⋯ The results of this study support the use of repeat DSA in patients with NPM-SAH; however, routine repeat DSA may not be indicated in PM-SAH patients. The routine use of MRI remains controversial.

In the Brazilian public national healthcare system, botulinum toxin type A has traditionally been the sole treatment option for patients with dystonia. However, as of October 2022, deep brain stimulation (DBS) garnered positive recommendations for the condition. This study aims to assess the cost-effectiveness of DBS in treating adults with generalized and cervical dystonia within the Brazilian healthcare context, considering its recent inclusion. ⋯ From the perspective of the Brazilian public health system, the combination of DBS and BCP appears to be cost-effective for the treatment of both generalized and cervical dystonia when compared to BCP alone.

Over the past 15 years, WORLD NEUROSURGERY (WN) has emerged as a pivotal source in the neurosurgery field, reflecting remarkable growth and development. Originally published as Surgical Neurology from 1973 to 2009, the journal transitioned to its current title in 2010, significantly expanding its reach and influence. ⋯ This study underscores WN's significant role in advancing neurosurgical research over the past 5 null decades. The findings highlight the journal's evolution, its expanding global influence, and the key contributors to its success.

Although pedicle screw and rod instrumentation remains the gold standard method of posterior rod fixation, it is associated with complications, including pedicle breach and facet joint violation. There is current interest in facet joint stabilization with the potential to create a less invasive, natural arch of fixation that may avoid the complications associated with pedicle screw and rod instrumentation. This study examined the stabilizing potential of a novel facet joint fixation device for single-level (L4-L5) fixation in a human cadaveric model. ⋯ Bilateral lumbar facet fixation with and without supplemental transfacet screw fixation provided significant stability. Cranial and caudal adjacent-level ROM was not influenced by facet fixation except for a slight increase in cranial segment motion during extension. Facet fixation did not alter the lordotic intervertebral disc angle at the instrumented level.
