Context: Chordomas are rare primary tumors of bone characterized by local aggressiveness and poor prognosis. The surgical exeresis plays a critical role for their management. Objective: The aim was to provide an overview of the surgical management of chordomas of the mobile spine and sacrum, describing the most common surgical approaches, the role of surgical margins, the difficulties of en block resection, the outcomes of surgery, the recurrence rate and the use of associated therapies. ⋯ Although radical surgery must still be considered the gold standard for the management of chordomas, a multidisciplinary approach is required to improve the local control of the disease in patients who undergo both radical and non-radical surgery. Adjuvant radiation therapy increases the continuous disease-free survival and the local recurrence-free survival. Level of evidence: Systematic review; level III.

Context/objective: To determine current barriers for clinical implementation of epidural stimulation for functional improvement after spinal cord injury and highlight applicable ethical constructs to approach future research. Design: Survey of spinal cord injury medicine physicians, January 2019. Setting: Spinal cord injury model systems hospital sites across the United States. ⋯ Numerous current barriers to clinical implementation were identified, including need for additional efficacy studies (92.9%), lack of clear guidelines on stimulation parameters (83.3%), and inability to identify which patients will benefit (76.2%). Conclusions: With multiple barriers to clinical implementation currently identified, evaluating this research with an eye toward the ethical construct of equipoise is increasingly relevant. Addressing these barriers may require modifications in both physician expectations and how researchers approach this work.

Study Design: Scoping review Objective: To study the design, clinical setting and outcome measures used in spinal cord injury rehabilitation publications. Methods: A literature search on PubMed and Medline was conducted focusing on articles published between 1990-2016 and using "traumatic SCI", "functional outcomes", "rehabilitation", "work" and "return to work" as outcomes. Studies were categorized based on design (intervention, including RCTs vs. non-intervention studies), settings (inpatient vs. outpatient vs. transition), and outcome measures used (impairment vs. function vs. participation/integration vs. quality of life vs. symptoms). ⋯ This is particularly true for tetraplegia. While standard measures of function were frequently used, providing valuable data, there is no consensus about what exact outcome measure to use. Using newer measurement techniques, for instance based on the application of item response theory, should be considered to enhance uniformity.

Objective: Persons with spinal cord injuries (SCI) experience rapid sublesional bone loss following injury (1, 3). Evidence on preventing/managing osteoporosis in SCI is lacking. This project examined how providers manage bone loss in SCI. ⋯ Providers indicated that patients often experienced psychological stress, anxiety and depression following fractures. Conclusion: Providers described a lack of evidence for screening and management of patients with SCI and osteoporosis. Future efforts should include developing evidence-informed guidelines to aid providers in osteoporosis management.

Start-up propulsion biomechanics changes with fatiguing activity in persons with spinal cord injury.
Objective: Shoulder pathology is a common condition in wheelchair users that can considerably impact quality of life. Shoulder muscles are prone to fatigue, but it is unclear how fatigue affects start-up propulsion biomechanics. This study determines acute changes in start-up wheelchair propulsion biomechanics at the end of a fatiguing propulsion protocol. ⋯ Conclusion: There are clear changes in overground propulsion biomechanics at the end of a fatiguing propulsion protocol. While reduced forces could protect the shoulder, these reduced forces come with shorter contact times and lower velocity. Investigating changes in start-up propulsion biomechanics with fatigue could provide insight into injury risk.
