Prevalence of and factors associated with stenotic thoracic ligamentum flavum hypertrophy.
Stenotic thoracic ligamentum flavum hypertrophy can cause leg and/or low back pain similar to that caused by lumbar spinal stenosis. However, the thoracic spine may occasionally be overlooked in patients with leg and/or low back pain. An accurate understanding of the prevalence of stenotic thoracic ligamentum flavum hypertrophy and its associated factors is necessary. ⋯ Given the possibility for missed stenotic thoracic ligamentum flavum hypertrophy to potentially result in neurological complications, extending lumbar spine MRI covering the lower thoracic region may be considered for patients over 50 years of age with suspected severe lumbar disc degeneration.

Optimal techniques of ultrasound-guided superficial and deep parasternal intercostal plane blocks: a cadaveric study.
The optimal techniques of a parasternal intercostal plane (PIP) block to cover the T2-T6 intercostal nerves have not been elucidated. This pilot cadaveric study aims to determine the optimal injection techniques that achieve a consistent dye spread over the second to sixth intercostal spaces after both ultrasound-guided superficial and deep PIP blocks. We also investigated the presence of the transversus thoracis muscle at the first to sixth intercostal spaces and its sonographic identification agreement, as well as the location of the internal thoracic artery in relation to the lateral border of the sternum. ⋯ Triple injections at the second, fourth, and fifth intercostal spaces for the superficial approach and double injections at the third and fifth intercostal spaces for the deep approach were optimal techniques of the PIP blocks.

Observational StudyRadiographic lead migration in percutaneous spinal cord stimulator trials.
Lead migration during spinal cord stimulator (SCS) trials is relatively neglected in the literature and presents a different set of challenges compared with fully implanted leads. There is no consensus on what constitutes a clinically significant amount of radiographic lead migration during SCS trials. We wished to evaluate the incidence and extent of radiographic lead migration during percutaneous SCS trials, to investigate the risk factors for lead migration and whether this has impacted on trial success. ⋯ Radiographic lead migration of approximately half of a vertebral level in a caudal direction can be expected during percutaneous SCS trials and this can be anticipated by siting leads half of a vertebral level higher to accommodate for this. Additional factors should be considered in the setting of radiographic lead migration to determine whether this can be considered clinically significant.

Oral opioid prescribing to active duty US military personnel: a cross-sectional population.
While civilian opioid prescriptions have seen a dramatic decline in recent years, there are few studies investigating trends in opioid prescription in the active duty military population. We evaluated oral opioid prescribing patterns to active duty military personnel in the Military Health System (MHS) from 2017 to 2020 to determine the incidence of opioid prescriptions as well as demographic and military-specific risk factors for receiving an oral opioid prescription. ⋯ The substantial decrease in oral opioid prescriptions to active duty military personnel mirrors data published in the civilian community. The identified risk factors for receiving an opioid prescription may be potential targets for future interventions to further decrease prescribing.

The clavipectoral fascia plane block (CPB) is a novel anesthetic management strategy proposed by Valdes-Vilches for clavicle fractures. This study aimed to investigate the distribution of the injected solution around the clavicle and the surrounding tissues. ⋯ The CPB effectively distributes the administered solution in the anterosuperior region of the clavicular periosteum, superficial muscular plane, and supraclavicular nerves. However, it does not affect the posteroinferior region of the clavicular periosteum or the deep muscular plane, including the CPF.
