We sought to identify predictors of failed triceps motor branch transfer to the anterior division of the axillary nerve (AN) for shoulder abduction reconstruction after a brachial plexus injury (BPI). ⋯ Use of triceps motor branch associated with fibrillations or weakness resulted in statistically poorer outcomes compared to the use of a normal triceps motor branch in the restoration of anterior AN function after nerve transfer.

This study aims to compare the clinical efficacy of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral asymmetric compression fracture (OVACF). ⋯ In our study, PVP and PKP are both effective in the treatment of OVACF, but PKP surgery had better long-term clinical efficacy.

Microsurgical techniques are increasingly being recommended for the treatment of symptomatic Tarlov cysts (TCs) due to improved long-term outcomes compared to those of other strategies. However, these techniques are associated with a high risk of cyst recurrence and cerebrospinal fluid (CSF) leakage, resulting in the surgical strategy of TCs remaining controversial. We hypothesize that incomplete closure of the ostium between the cyst and the subarachnoid space is the probable cause of surgical failure. Accordingly, we present a novel method of cyst separation and ostium closure that aims to block the ostium more firmly and reliably. ⋯ The microscopic fenestration of cysts and modified ostium obstruction described herein is a safe and effective strategy for management of patients with symptomatic TCs and is associated with a low incidence of cyst recurrence and CSF leakage since it achieves complete closure of cyst ostium.

Traditionally, C1 fractures have been designated as stable or unstable based on the inherent integrity of the transverse altantal ligament. The purpose of our study was to identify adult trauma patients with C1 fractures on cervical computed tomography and evaluate whether C1-C2 alignment differed in patients with and without an associated transverse atlantal ligament injury on follow-up cervical magnetic resonance imaging. ⋯ Lateral ADI asymmetry (using a cutoff of >3 mm), combined C1 lateral mass offset, and anterior ADI demonstrate robust specificity to "rule in" transverse atlantal ligament injury. Atlantoaxial alignment was overall relatively insensitive as a screening test although sensitivity can be improved using a cutoff of >2 mm for lateral ADI asymmetry. Our findings reinforce the role of cervical magnetic resonance imaging in the diagnostic workup and clinical management of trauma patients with an acute burst fracture of the C1 vertebra.

Hospital length of stay (HLOS) after traumatic brain injury (TBI) is an important metric of injury severity, resource utilization, and access to post-acute care services. Risk factors for protracted HLOS after TBI require further characterization. ⋯ XHLOS patients were more likely to have severe injuries, low SES, and Medicaid. XHLOS is associated with in-hospital mortality and need for post-acute placement. XHLOS patients often demonstrated medical stability long before placement, underscoring complex relationships between SES, health insurance, and outcome. These findings have important implications for quality improvement and resource utilization at acute care hospitals and await validation from larger trials.
