Study Design: Prospective cohort study.
Objectives: To determine the extent of functional recovery between 6 and 12 months following a traumatic spinal cord injury (TSCI) and to identify individuals achieving a small clinical functional improvement during this period.
Setting: A single level-1 trauma center specialized in SCI care.
Methods: A cohort of 125 patients sustaining TSCI was studied. The Spinal Cord Independence Measure (SCIM) version III at 6 and 12 months post injury was used as the main outcome measure.
Results: The observed functional improvement for the final cohort did not reach a clinically significant level between 6 and 12 months post injury. However, 30.4% of individuals achieved this level (≥4 points in the SCIM-III total score). This group showed a higher proportion of motor-complete TSCI (AIS grade A or B) and showed a tendency toward older age and higher trauma severity. Longer duration of intensive functional rehabilitation was the single factor associated with reaching a small clinically important improvement in the SCIM-III total score.
Conclusions: Functional status between 6 and 12 months following a TSCI may be considered clinically similar, regardless of the level of injury. However, 30% may reach a small clinical functional improvement in the subacute to chronic phase following TSCI, particularly individuals sustaining severe deficits and older age, which may highlight the importance of functional compensation during this period for these patients.

Is it possible to return to skiing following long-construct spinal deformity surgery?
Spine Deform

Department of Orthopaedic Surgery, Columbia University Irving Medical Center, NewYork-Presbyterian Och Spine Hospital, New York, NY, 10032, USA.
Background: Alpine skiing requires flexibility, endurance, strength and rotational ability, which may be lost after long fusions to the pelvis for adult spinal deformity (ASD). ASD patients may worry about their ability to return to skiing (RTS) postoperatively. There is currently insufficient data for spine surgeons to adequately address questions about when, or if, their patients might RTS.

Neuropathic pain (NP) imposes a significant burden on individuals, manifesting as nociceptive anaphylaxis, hypersensitivity, and spontaneous pain. Previous studies have shown that traumatic stress in the nervous system can lead to excessive production of hydrogen sulfide (HS) in the gut. As a toxic gas, it can damage the nervous system through the gut-brain axis.

Objectives: This study aims to review the societal, economic, and racial factors that impact the usage of spinal cord stimulation for chronic pain. Our working hypothesis is that patients of ethnic minority groups or of lower socioeconomic status (SES) status may have lower implantation rates and usage of spinal cord stimulation (SCS).
Materials And Methods: Our study sourced publications from PubMed, Embase, and Cochrane Library on December 21st, 2023 for SCS for the purposes of pain management.
Differential Neuronal Activation of Nociceptive Pathways in Neuropathic Pain After Spinal Cord Injury.

Neuropathic pain, a prevalent complication following spinal cord injury (SCI), severely impairs the life quality of patients. No ideal treatment exists due to incomplete knowledge on underlying neural processes. To explore the SCI-induced effect on nociceptive circuits, the protein expression of c-Fos was analyzed as an indicator of neuronal activation in a rat contusion model exhibiting below-level pain.

The Canadian Association of Radiologists (CAR) Central Nervous System Expert Panel is made up of physicians from the disciplines of radiology, emergency medicine, neurosurgery, and neurology, a patient advisor, and an epidemiologist/guideline methodologist. After developing a list of 24 clinical/diagnostic scenarios, a rapid scoping review was undertaken to identify systematically produced referral guidelines that provide recommendations for one or more of these clinical/diagnostic scenarios. Recommendations from 55 guidelines and contextualization criteria in the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) for guidelines framework were used to develop 51 recommendation statements across the 24 scenarios.
