Abstract
The purpose of this systematic review was to identify outdoor environmental risk factors associated with falls and/or fear of falling among older adults. PubMed, EMBASE, and CINAHL were searched through February 19, 2021. Studies were included if they measured outdoor environment, falls or fear of falling as an outcome, and included adults aged ≥ 45 years. Excluded studies were not published in English and/or did not include original results. Two study-team members completed abstract screening. For full text reviews, a third reviewer resolved conflicts. A total of 5,727 abstracts were screened and 462 full texts were reviewed. After full-text review, approximately 25 studies will be assessed for risk of bias and data extracted by two independent reviewers. Based on the initial review, uneven outdoor surfaces, busy traffic areas, and neighborhood disorder were associated with falls/fear of falling among older adults. Modifiable outdoor environmental factors may be targets for fall prevention.

Abstract
Phanor Leonidas Perot Jr., MD, PhD (1928-2011), was a gifted educator and pioneer of academic neurosurgery in South Carolina. As neurosurgical resident and then as a junior faculty member at the Montreal Neurological Institute, he advanced understandings of both epilepsy and spinal cord injury under Wilder Penfield, William Cone, and Theodore Rasmussen. In 1968, he moved to Charleston to lead neurosurgery. From his time spent with master physicians such as Isidor Ravdin and Wilder Penfield, Perot himself became "the ultimate teacher." His research spanned the fields of epilepsy to torticollis to spinal trauma, focusing the most on the basic pathophysiology of spinal cord damage elucidated through somatosensory evoked potentials. His research was distinguished by generous grant funding. By the time he stepped down as chairman in 1997, the division of neurosurgery had become a department and he had served as president of the American Academy of Neurological Surgery and the Society of Neurological Surgeons. Perot taught prolifically at the bedside, and considered the residency program at the Medical University of South Carolina his greatest achievement. Although Dr. Perot never fully retired, he also enjoyed active hobbies of fly-fishing, traveling, and hunting, until his death on February 2, 2011. He influenced many and earned his role in history as the father of academic neurosurgery in South Carolina.

Abstract
IMPORTANCE There is substantial controversy with regards to the adequacy and use of noncontrast head computed tomography (NCCT) for late-window acute ischemic stroke in selecting candidates for mechanical thrombectomy. OBJECTIVE To assess clinical outcomes of patients with acute ischemic stroke presenting in the late window who underwent mechanical thrombectomy stratified by NCCT admission in comparison with selection by CT perfusion (CTP) and diffusion-weighted imaging (DWI). DESIGN, SETTING, AND PARTICIPANTS In this multicenter retrospective cohort study, prospectively maintained Stroke Thrombectomy and Aneurysm (STAR) database was used by selecting patients within the late window of acute ischemic stroke and emergent large vessel occlusion from 2013 to 2021. Patients were selected by NCCT, CTP, and DWI. Admission Alberta Stroke Program Early CT Score (ASPECTS) as well as confounding variables were adjusted. Follow-up duration was 90 days. Data were analyzed from November 2021 to March 2022. EXPOSURES Selection by NCCT, CTP, or DWI. MAIN OUTCOMES AND MEASURES Primary outcome was functional independence (modified Rankin scale 0-2) at 90 days. RESULTS Among 3356 patients, 733 underwent late-window mechanical thrombectomy. The median (IQR) age was 69 (58-80) years, 392 (53.5%) were female, and 449 (65.1%) were White. A total of 419 were selected with NCCT, 280 with CTP, and 34 with DWI. Mean (IQR) admission ASPECTS were comparable among groups (NCCT, 8 [7-9]; CTP, 8 [7-9]; DWI 8, [7-9]; P = .37). There was no difference in the 90-day rate of functional independence (aOR, 1.00; 95% CI, 0.59-1.71; P = .99) after adjusting for confounders. Symptomatic intracerebral hemorrhage (NCCT, 34 [8.6%]; CTP, 37 [13.5%]; DWI, 3 [9.1%]; P = .12) and mortality (NCCT, 78 [27.4%]; CTP, 38 [21.1%]; DWI, 7 [29.2%]; P = .29) were similar among groups. CONCLUSIONS AND RELEVANCE In this cohort study, comparable outcomes were observed in patients in the late window irrespective of neuroimaging selection criteria. Admission NCCT scan may triage emergent large vessel occlusion in the late window.

Abstract
IMPORTANCE Limited data are available about the outcomes of mechanical thrombectomy (MT) for real-world patients with stroke presenting with a large core infarct. OBJECTIVE To investigate the safety and effectiveness of MT for patients with large vessel occlusion and an Alberta Stroke Program Early Computed Tomography Score (ASPECTS) of 2 to 5. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study used data from the Stroke Thrombectomy and Aneurysm Registry (STAR), which combines the prospectively maintained databases of 28 thrombectomy-capable stroke centers in the US, Europe, and Asia. The study included 2345 patients presenting with an occlusion in the internal carotid artery or M1 segment of the middle cerebral artery from January 1, 2016, to December 31, 2020. Patients were followed up for 90 days after intervention. The ASPECTS is a 10-point scoring system based on the extent of early ischemic changes on the baseline noncontrasted computed tomography scan, with a score of 10 indicating normal and a score of 0 indicating ischemic changes in all of the regions included in the score. EXPOSURE All patients underwent MT in one of the included centers. MAIN OUTCOMES AND MEASURES A multivariable regression model was used to assess factors associated with a favorable 90-day outcome (modified Rankin Scale score of 0-2), including interaction terms between an ASPECTS of 2 to 5 and receiving MT in the extended window (6-24 hours from symptom onset). RESULTS A total of 2345 patients who underwent MT were included (1175 women [50.1%]; median age, 72 years [IQR, 60-80 years]; 2132 patients [90.9%] had an ASPECTS of ≥6, and 213 patients [9.1%] had an ASPECTS of 2-5). At 90 days, 47 of the 213 patients (22.1%) with an ASPECTS of 2 to 5 had a modified Rankin Scale score of 0 to 2 (25.6% [45 of 176] of patients who underwent successful recanalization [modified Thrombolysis in Cerebral Ischemia score ≥2B] vs 5.4% [2 of 37] of patients who underwent unsuccessful recanalization; P = .007). Having a low ASPECTS (odds ratio, 0.60; 95% CI, 0.38-0.85; P = .002) and presenting in the extended window (odds ratio, 0.69; 95% CI, 0.55-0.88; P = .001) were associated with worse 90-day outcome after controlling for potential confounders, without significant interaction between these 2 factors (P = .64). CONCLUSIONS AND RELEVANCE In this cohort study, more than 1 in 5 patients presenting with an ASPECTS of 2 to 5 achieved 90-day functional independence after MT. A favorable outcome was nearly 5 times more likely for patients with low ASPECTS who had successful recanalization. The association of a low ASPECTS with 90-day outcomes did not differ for patients presenting in the early vs extended MT window.

Abstract
Introduction:
Recent trials have proven safety and efficacy of mechanical thrombectomy for patients presenting with emergent large vessel occlusion beyond 6 hours of symptom onset. While evidence supports using baseline CT scan to evaluate the candidacy for mechanical thrombectomy for patients presenting in the early window, late window trials have used advanced imaging such as CT and MR perfusion. We aim to assess outcomes of MT stratified by admission Alberta Stroke Program Early CT Score (ASPECTS).
Methods:
We used data from the prospectively maintained registries of 28 stroke centers in the Stroke Thrombectomy and Aneurysm (STAR) collaboration. Demographics, comorbidities, LVO site, ASPECTS, MT technique, radiographic and clinical outcome data were collected. Patients with M1 or ICA occlusion were included in these analyses. Multivariable analysis was performed using a generalized linear model with logit link to assess for variables associated with favorable outcomes.
Results:
3356 patients in the STAR database were reviewed and 347 (10.3%) of those underwent MT in the late window (table). Median age was 69, 189 (54.5%) were female, and 181 (52.2%) were white. 295 patients ASPECTS ≥6. In this group, 200 (68.8%) had M1 occlusion, and the remaining had ICA occlusion. Aspiration thrombectomy was used in 139 (47.1%) of patients. Successful reperfusion was achieved (mTICI≥2b) in 264 (76.1%). sICH was observed in 15 (5.1%). Excellent functional outcome (mRS 0-2) was observed in 124 (42%) patients. ASPECTS score was independently associated with favorable outcomes (aOR 1.2, 95% CI 1.1-1.4, P=0.006).
Conclusion:
Excellent outcomes are observed in patients with good ASPECT score presenting in the late window irrespective of perfusion criteria. Admission CT scan could be used to triage patients presenting with emergent large vessel occlusion beyond 6 hours of symptom onset.

Abstract
Introduction:
Patients with poor baseline images were excluded from most clinical trials so the data about whether these patients could benefit from MT remains unknown. In this study, we aim to investigate the safety and efficacy of MT in patients with large vessel occlusion (LVO) and large core infarct (LCI).
Methods:
The Stroke Thrombectomy and Aneurysm Registry (STAR) was interrogated. We included thrombectomy patients presenting with LVO within 24 hours and with a LCI as defined by Alberta Stroke Program Early CT Score (ASPECTS) < 6. Patients presenting within 6 hours of last known normal (LKN) were considered in the early window and patients presenting after 6 hours were considered in the late window. 90-day outcomes were assessed. We used a logistic regression model to assess the factors associated with good 90-day outcome in patients in the early and late windows.
Results:
144 patients were included in this study (table). Median age was 69 and 92 (64%) patients were treated in the early MT window. ICA was the most common site of occlusion (48.6%) and ADAPT was used in 34.7%. Admission NIHSS was 17.5. Successful recanalization (TICI>2b) was achieved in 84.7% and median procedure time was 54 minutes. sICH hemorrhage was observed in 22 (15.3%). Median mRS was 4 at 90 days. Favorable outcome was observed in 41 patients (28.5%) and mortality occurred in in 59 (41%). There was no difference in 90-day functional outcome between patients in early and late windows. In patients presenting in the early window, age (aOR=0.905, p=0.0002) and baseline NIHSS (aOR=0.909, p=0.0423) were independently associated with 90-day outcome. In patients presenting in the late window, only age (aOR=0.934, p=0.0069) was independently associated with good outcome.
Conclusion:
More than one in four patients presenting with ASPECTS<6 may achieve functional independence at 90-day following MT. Patient age remains the main predictor of 90-day outcome in patients with low ASPECTS in both late and early windows.

Abstract
As an increasing number of states begin to legalize marijuana for either medical or recreational use, it is important to determine its effects on joint arthroplasty. The purpose of this study is to determine the impact of cannabis use on total knee arthroplasty (TKA) revision incidence, revision causes, and time to revision by analyzing the Medicare database between 2005 and 2014. A retrospective review of the Medicare database for TKA, revision TKA, and causes was performed utilizing Current Procedural Terminology (CPT) and International Classification of Disease ninth revision codes (ICD-9). Patients who underwent TKA were cross-referenced for a history of cannabis use by querying ICD-9 codes 304.30-32 and 305.20-22. The resulting group was then longitudinally tracked postoperatively for revision TKA. Cause for revision, time to revision, and gender were also investigated. Our analysis returned 2,718,023 TKAs and 247,112 (9.1%) revisions between 2005 and 2014. Cannabis use was prevalent in 18,875 (0.7%) of TKA patients with 2,419 (12.8%) revisions within the cannabis cohort. Revision incidence was significantly greater in patients who use cannabis (p < 0.001). Time to revision was also significantly decreased in patients who used cannabis, with increased 30- and 90-day revision incidence compared to the noncannabis group (P < 0.001). Infection was the most common cause of revision in both groups (33.5% nonusers versus 36.6% cannabis users).Cannabis use may result in decreasing implant survivorship and increasing the risk for revision within the 90-day global period compared to noncannabis users following primary TKA.

Recanalization of bilateral ICA with thrombolysis in cerebral infarction (TICI) grade 0 to left TICI 2b flow with distal left A1 occlusion and right TICI 3 flow was achieved in 32 min with the use of simultaneous catheterization and aspiration thrombectomies.
CONCLUSION
The described technique offers an efficient and feasible means to reduce time to recanalization and radiation in cases of bilateral LVO.

Abstract
Background High failure rates and unacceptable patient outcomes have kept total ankle arthroplasty (TAA) from becoming a favorable treatment option. Modern prosthetic designs and techniques have improved outcomes and decreased revision rates. Current literature has not adequately investigated the recent trends in TAA utilization and revision rate. The purpose of this study was to determine the trends in TAA utilization and the rate of revision TAA by analyzing a comprehensive Medicare database for procedures performed between 2005 and 2012. Methods A retrospective review of a comprehensive Medicare database within the PearlDiver Supercomputer application (Warsaw, IN) of the index procedures TAA and revision TAA was conducted. Patients who underwent TAA and revision TAA were identified by Current Procedural Terminology (CPT)-27702, 27703, and International Classification of Disease ninth revision (ICD) codes 81.56, 81.59 respectively. The primary outcomes of this study were annual revision incidence and TAA annual utilization. Demographic data such as age, gender, and geographical location of patients were also examined. Results Within our study period of 2005-2012 there was a reported total of 7,181 TAAs and 1,431 revision TAAs which is a revision incidence of 19.928% amongst the Medicare population. The compound annual growth rate (CAGR) was 16.37% for TAA, 7.74% for revision TAA, and a mean 7.41% annual revision incidence. Amongst females there were 3,568 TAA and 731 revision TAA compared with 3,336 TAA and 613 revision TAA amongst males. The greatest amount of TAA and revision TAA were found in the 65-69 age group followed by the 70-74 age group. Regionally, the highest number of TAA and revision TAA were found in the South and the lowest in the Northeast. Conclusions Our analysis of the Medicare database shows that there is a high rate of annual growth in TAA utilization (16.37%) and revision TAA (7.74%) indicating that there is an increased demand for TAA in the Unites States. However, failed TAA can have serious consequence and revision TAA remains to have suboptimal results. This study highlights the recent trends in ankle arthroplasty and serves to increase awareness of this increasingly popular procedure.

Abstract
INTRODUCTION The purpose of this study was to: 1) determine the incidence of revision total knee arthroplasty (TKA); 2) correlate the percent of glycated hemoglobin with incidence of revision; and 3) determine the cause of revision in diabetic patients stratified by a glycated hemoglobin level. MATERIALS AND METHODS We analyzed 424,107 patients from a national private payer database from 2007 to 2015 to determine who had diabetes and underwent TKA. We determined the incidence of revision TKA in the overall cohort and stratified it by glycated hemoglobin levels. Correlation analysis between the levels of glycated hemoglobin and the incidence of revision TKA was performed. We performed descriptive statistics of the underlying cause of revision TKA in both the overall and stratified cohorts. RESULTS There was a 3.2% incidence of revision in the overall cohort. When stratified by glycated hemoglobin levels, the cohort in the 6.6 to 7.0% category had the lowest incidence of revision (2.9%). The cohorts in the 8.6 to 9% glycated hemoglobin category had the highest revision rate (4.7%). There was a significantly positive correlation between rate of revision and ascending glycated hemoglobin levels, and a significantly negative correlation between descending glycated hemoglobin levels and revision incidence. The most common cause of revision was infection in the overall and stratified groups. CONCLUSION Sub-optimal glycated hemoglobin levels in diabetic patients correlated with increased revision rates in those who underwent TKA. Management of diabetics should be optimized before undergoing TKA to minimize revision surgery risk.

Abstract
OBJECT
A systematic review of the available evidence on the prophylactic and therapeutic use of flaps for the coverage of complex spinal soft-tissue defects was performed to determine if the use of flaps reduces postoperative complications and improves patient outcomes.
METHODS
A PubMed database search was performed to identify English-language articles published between 1990 and 2014 that contained the following phrases to describe postoperative wounds (“wound,” “complex back wound,” “postoperative wound,” “spine surgery”) and intervention (“flap closure,” “flap coverage,” “soft tissue reconstruction,” “muscle flap”).
RESULTS
In total, 532 articles were reviewed with 17 articles meeting the inclusion criteria of this study. The risk factors from the pooled analysis of 262 patients for the development of postoperative complex back wounds that necessitated muscle flap coverage included the involvement of instrumentation (77.6%), a previous history of radiotherapy (33.2%), smoking (20.6%), and diabetes mellitus (17.2%). In patients with instrumentation, prophylactic coverage of the wound with a well-vascularized flap was shown to result in a lower incidence of wound complications. One study showed a statistically significant decrease in complications compared with patients where prophylactic coverage was not performed (20% vs 45%). The indications for flap coverage after onset of wound complications included hardware exposure, wound infection, dehiscence, seroma, and hematoma. Flap coverage was shown to decrease the number of surgical debridements needed and also salvage hardware, with the rate of hardware removal after flap coverage ranging from 0% to 41.9% in 4 studies.
CONCLUSIONS
Prophylactic coverage with flaps in high-risk patients undergoing spine surgery reduces complications, while therapeutic coverage following wound complications allows the salvage of hardware in the majority of patients.
