#lowbackpain on TikTok: A New Frontier for Orthopaedic Medical Education.

INTRODUCTION: Low back pain has become a substantial health problem in all developed countries. Many healthcare professionals and content creators have begun sharing their treatment methods and opinions through social media, especially the video-based platform TikTok. TikTok has been downloaded more than 2.6 billion times with over a billion daily users. Its influence on public health makes it imperative that information be accurate and safe. This study aims to analyze TikTok's most popular content on lower back pain and how orthopaedic surgeons contribute on this growing platform. OBJECTIVES: To analyze TikTok's most popular content on lower back pain and how orthopaedic surgeons are and can contribute on this growing platform. METHODS: A TikTok search conducted on April 22, 2023, using the terms '#lowerbackpain'and '#lowbackpainrelief,' resulted in numerous videos, 100 of which met inclusion criteria. Videos were included if they were related to the content, had more than 1000 views, were in English, and were not duplicates. Video characteristics were recorded and evaluated for quality by two reviewers using DISCERN. A two-sample t-test was used to assess differences. RESULTS: Overall, the top videos on lower back pain had an average of 2,061,396 views, with a mean DISCERN score of 34. The mean total DISCERN score was 36 and 34 for physicians and nonphysicians, respectively, while the video by the orthopaedic surgeon (n = 1) scored 31. The most recommended treatments included at-home exercises (n = 75) and visiting a chiropractor (n = 4). CONCLUSION: We find that the information presented by nonphysicians offered quick, at-home fixes to medical problems without offering any research or proven data to support their claims. We cannot overlook Tiktok's immense influence in the realm of orthopaedic health as it has become a sphere of information dissemination and education. Thus, we suggest that there is not necessarily a need for a greater number of surgeons and/or resident physicians to involve themselves on the platform, but rather the involvement of governing bodies and spine societies to put out position statements for our patients.

Perioperative Nutritional, Functional, and Bone Health Optimization in Spine Surgery: A National Investigation of Spine Surgeons' Perceptions and Practices.

INTRODUCTION: While perioperative nutritional, functional, and bone health status optimization in spine surgery is supported with ample evidence, the implementation and surgeon perception regarding such efforts in clinical practice remain largely unexplored. This study sought to assess the current perception of spine surgeons and implementation regarding the nutritional, functional status, and bone health perioperative optimization. METHODS: An anonymous 30-question survey was distributed to orthopaedic spine fellowship and neurosurgery program directors identified through the North American Spine Society and American Association of Neurological Surgeons contact databases. RESULTS: The questionnaire was completed by 51 surgeon survey respondents. Among those, 62% reported no current formal nutritional optimization protocols with 14% not recommending an optimization plan, despite only 10% doubting benefits of nutritional optimization. While 5% of respondents perceived functional status optimization as nonbeneficial, 68% of respondents reported no protocol in place and 46% noted a functional status assessment relying on patient dependency. Among the respondents, 85% routinely ordered DEXA scan if there was suspicion of osteoporosis and 85% usually rescheduled surgery if bone health optimization goals were not achieved while 6% reported being suspicious of benefit from such interventions. CONCLUSION: While most responding spine surgeons believe in the benefit of perioperative nutritional and functional optimization, logistical and patient compliance challenges were noted as critical barriers toward optimization. Understanding surgeon perception and current practices may guide future efforts toward advancement of optimization protocols.

Efficacy and Outcome Measurement of iFactor/ABM/P-15 in Lumbar Spine Surgery: A Systematic Review.

STUDY DESIGN: Systematic Review. OBJECTIVES: To determine the efficacy and overall outcomes of iFactor/ABM/P-15 following lumbar spine surgery. METHODS: We performed a search of the Cochrane Library, Medline Ovid, PubMed, and SCOPUS databases from inception until August 2023. Eligible studies included outcomes of patients receiving iFactor following lumbar spine surgery. The primary outcomes of interest were fusion rates and iFactor efficacy after lumbar surgery in patients who received iFactor. Secondary outcomes included patient-reported outcomes and complication rates. RESULTS: A total of 766 titles were initially screened. After inclusion criteria were applied, 5 studies (388 patients) were included, which measured overall outcomes of iFactor/ABM/P-15 following lumbar spine surgery. These studies showed acceptable reliability for inclusion based on the Methodical Index for Non-Randomized studies and Critical Appraisal Skills Programme assessment tools. iFactor/ABM/P-15 facilitated significantly faster bone development in various procedures while maintaining favorable clinical outcomes compared to traditional grafts. CONCLUSIONS: This systematic review found that iFactor/ABM/P-15 use for lumbar spine surgery maintains similar managing patient-reported outcomes relative to other grafting methods. In regard to rates of fusion, iFactor/ABM/P-15 showed a significantly faster rate of fusion when compared to traditional grafts including allograft, autograft, demineralized bone matrix (DBM), and recombinant human bone morphogenetic protein-2 (rhBMP-2). Future multicenter randomized control trials with larger sample sizes are recommended to further assess iFactor/ABM/P-15 efficacy in lumbar spine surgery.

Mechanisms and timing of injury to the thoracic, lumbar and sacral spine in simulated underbody blast PMHS impact tests.

During an underbody blast (UBB) event, mounted occupants are exposed to high rate loading of the spine via the pelvis. The objective of this study was to simulate UBB loading conditions and examine mechanisms of injury in the thoracic, lumbar and sacral spine. Fourteen instrumented, whole-body, postmortem human subject (PMHS) experiments were performed using the WSU-decelerative horizontal sled system. The specimens were positioned supine on a decelerative sled, which then impacted an energy absorbing system mounted to a concrete barrier. Variables included the peak velocity and time-to-peak velocity for seat and floor, and the presence or absence of personal protective equipment (PPE) and seat padding. Post-test CT scans and autopsies were performed to identify the presence and severity of injuries. Acceleration and angular rate data collected at vertebra T1, T5, T8, T12, and S1 were used to assess injury timing and mechanisms. Additionally, joint time-frequency analysis (JTFA) of the spinal Z acceleration of the sacrum and vertebrae was developed with the aim of verifying spinal fracture timing. Injuries observed in the spine were attributed to axial compression applied through the pelvis, together with flexion moment due to the offset in the center of gravity of the torso, and are consistent with UBB-induced combat injuries reported in the literature. The injury timing estimation techniques discussed in this study provide a time interval when the fractures are predicted to have occurred. Furthermore, this approach serves as an alternative to the estimation methods using acoustic sensors, force and acceleration traces, and strain gauges.
