Cadaveric descriptions of the deep layer of the lumbar ligamentum flavum (LF), extending between contiguous borders of adjacent laminae and into the lateral spinal canal region are limited. ⋯ We describe our observations of the deep LF in the human lumbar spine. These observations have clinical relevance for the interpretation of radiologic imaging and the performance of adequate decompression in the setting of spinal stenosis.

There are often multiple surgical treatment options for a spinal pathology. In addition, there is a lack of data that define differences in surgical treatment among surgeons in the United States. ⋯ Significant differences exist among US spine surgeons in the surgical treatment of recurrent lumbar disc herniations. It will become increasingly important to understand the underlying reasons for these differences and to define the most cost-effective surgical strategies for these common lumbar pathologies as the United States moves closer to a value-based health-care system.

Epidural steroid injections (ESIs) have been used for a number of years in the treatment of radicular pain caused by nerve root impingement or stenosis after failed conservative treatments with oral medications, physical therapy, and lifestyle modifications. ⋯ Predictive tools for ESI outcomes, such as nerve root compression grading and inflammatory markers, particularly, elevated IFN-γ from epidural lavage fluid, seem promising in the future. At this time, future research is needed with a larger sample size, broader spectrum of patients, and a more defined system of outcome measurements at standardized follow-up periods before practice recommendations can be made.

The incidence and relevant risk of ischemic stroke after cervical spine trauma remain unknown. ⋯ This analysis revealed that ischemic stroke after cervical spine injury was not uncommon and was associated with increased mortality and morbidity. Occurrence of ischemic stroke was significantly associated with age, comorbidities such as diabetes, and consciousness level at admission, but not with the type of spine injury.

Magnetically-controlled growing rod (MCGR) technology has been reported for the treatment of early-onset scoliosis (EOS). Such technology allows for regular and frequent outpatient rod distractions without the need for additional surgery. However, pre- and postdistraction spine radiographs are required to verify the amount of lengthening. This increased exposure to ionizing radiation in developing children significantly increases their risk profile for radiation-induced cancer and noncancerous morbidity. ⋯ This is the first study to report the use of a novel technique using noninvasive, nonionizing ultrasound to reliably document rod distractions in EOS patients. A high level of inter- and intrarater reliabilities were noted. More importantly, the use of ultrasonography may result in fewer whole spine radiographs from being taken in patients who have had MCGRs implanted for EOS; thereby decreasing their exposure to ionizing radiation and the potential risk of future radiation-induced diseases.
