Abstract
STUDY DESIGN Preclinical animal study. OBJECTIVE Evaluate the osteoinductivity and bone regenerative capacity of BioRestore bioactive glass. SUMMARY OF BACKGROUND DATA BioRestore is a Food and Drug Administration (FDA)-approved bone void filler that has not yet been evaluated as a bone graft extender or substitute for spine fusion. METHODS In vitro and in vivo methods were used to compare BioRestore with other biomaterials for the capacity to promote osteodifferentiation and spinal fusion. The materials evaluated (1) absorbable collagen sponge (ACS), (2) allograft, (3) BioRestore, (4) Human Demineralized Bone Matrix (DBM), and (5) MasterGraft. For in vitro studies, rat bone marrow-derived stem cells (BMSC) were cultured on the materials in either standard or osteogenic media (SM, OM), followed by quantification of osteogenic marker genes (Runx2, Osx, Alpl, Bglap, Spp1) and alkaline phosphatase (ALP) activity. Sixty female Fischer rats underwent L4-5 posterolateral fusion (PLF) with placement of 1 of 5 implants: (1) ICBG from syngeneic rats; (2) ICBG+BioRestore; (3) BioRestore alone; (4) ICBG+Allograft; or (5) ICBG+MasterGraft. Spines were harvested 8 weeks postoperatively and evaluated for bone formation and fusion via radiography, blinded manual palpation, microCT, and histology. RESULTS After culture for 1 week, BioRestore promoted similar expression levels of Runx2 and Osx to cells grown on DBM. At the 2-week timepoint, the relative ALP activity for BioRestore-OM was significantly higher (P<0.001) than that of ACS-OM and DBM-OM (P<0.01) and statistically equivalent to cells grown on allograft-OM. In vivo, radiographic and microCT evaluation showed some degree of bridging bone formation in all groups tested, with the exception of BioRestore alone, which did not produce successful fusions. CONCLUSIONS This study demonstrates the capacity of BioRestore to promote osteoinductivity in vitro. In vivo, BioRestore performed similarly to commercially available bone graft extender materials but was incapable of producing fusion as a bone graft substitute. LEVEL OF EVIDENCE Level V.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE The aim of this study was to determine the incidence of and risk factors for persistent opioid use after elective cervical and lumbar spine procedures and to quantify postoperative healthcare utilization in this patient population. METHODS Patients were retrospectively identified who underwent elective spine surgery for either cervical or lumbar degenerative pathology between November 1, 2013, and September 30, 2018, at a single academic center. Patients were split into 2 cohorts, including patients with and without opioid use at 180-days postoperatively. Baseline patient demographics, underlying comorbidities, surgical variables, and preoperative/postoperative opioid use were assessed. Health resource utilization metrics within 1 year postoperatively (ie, imaging studies, emergency and urgent care visits, hospital readmissions, opioid prescriptions, etc.) were compared between these 2 groups. RESULTS 583 patients met inclusion criteria, of which 16.6% had opioid persistence after surgery. Opioid persistence was associated with ASA score ≥3 (P = .004), diabetes (P = .019), class I obesity (P = .012), and an opioid prescription in the 60 days prior to surgery (P = .006). Independent risk factors for opioid persistence assessed via multivariate regression included multi-level lumbar fusion (RR = 2.957), cervical central stenosis (RR = 2.761), and pre-operative opioid use (RR = 2.668). Opioid persistence was associated with higher rates of health care utilization, including more radiographs (P < .001), computed tomography (CT) scans (.007), magnetic resonance imaging (MRI) studies (P = .014), emergency department (ED) visits (.009), pain medicine referrals (P < .001), and spinal injections (P = .003). CONCLUSIONS Opioid persistence is associated with higher rates of health care utilization within 1 year after elective spine surgery.

Abstract
The widespread success of cervical disc arthroplasty (CDA) has led to an interest in expanding indications beyond those outlined in the initial Food and Drug Administration investigational device exemption studies. Some of these off-label indications currently include 3-level and 4-level CDA, hybrid constructs with adjacent segment anterior cervical discectomy and fusion or corpectomy constructs, pre-existing kyphosis, revision of a failed anterior cervical discectomy and fusion to a CDA, CDA in the setting of significant degenerative disc disease and/or facet joint arthropathy, CDA for congenital cervical stenosis, and CDA in the presence of ossification of the posterior longitudinal ligament. This review article will summarize the current literature pertaining to the aforementioned indications.

Abstract
Background Trends between the sexes have been reported regarding prevalence, patient-reported outcomes (PROs), and complications of hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS), yet current results lack consensus. Purpose To evaluate sex-based differences after HA for FAIS in (1) prevalence of cam and pincer morphology in FAIS and (2) PROs, pain scores, and postoperative complication rates. Study Design Systematic review; Level of evidence, 4. Methods The EMBASE, PubMed, and Ovid (MEDLINE) databases were searched from establishment to February 28, 2022, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Included studies had sex-based data on prevalence, outcomes, and complications of HA for FAIS. Reviews and commentaries were excluded. Data were combined, and between-sex differences were analyzed. Meta-analyses using random-effects models were performed when possible. Pooled risk ratios (RRs) and standardized mean differences were calculated. Results A total of 74 studies were included (213,059 patients; 132,973 female hips [62.4%] and 80,086 male hips [37.6%]). The mean age was 30.7 ± 7.7 years among male patients and 31.1 ± 7.8 years among female patients. Male patients experienced mixed-type impingement significantly more often (39.4% vs 27.2% for female patients; RR = 0.69 [95% confidence interval [CI], 0.58-0.81]; P < .001), whereas female patients experienced pincer-type impingement more often (50.6% vs 30.8% for male patients; RR = 2.35 [95% CI, 1.14-4.86]; P = .02). Male patients had higher likelihoods of undergoing femoroplasty (89.8% vs 77.4% for female patients; RR = 0.90 [95% CI, 0.83-0.97]; P = .006), acetabuloplasty (67.1% vs 59.3% for female patients; RR = 0.87 [95% CI, 0.79-0.97]; P = .01), or combined femoroplasty/acetabuloplasty (29.2% vs 14.5% for female patients; RR = 0.63 [95% CI, 0.44-0.90]; P = .01). Although female patients showed greater improvements in Hip Outcome Score-Sport-Specific subscale (P = .005), modified Harris Hip Score (P = .006), and visual analog scale pain (P < .001), both sexes surpassed the minimal clinically important difference at 1, 2, and 5 years postoperatively. Female patients had higher complication rates (P = .003), although no sex-based differences were found in total hip arthroplasty conversion rates (P = .21). Conclusion Male patients undergoing HA for FAIS had a higher prevalence of mixed-type FAIS while female patients had more pincer-type FAIS. Female patients gained greater improvements in PROs, although both sexes exceeded the minimal clinically important difference, suggesting that both male and female patients can benefit from HA.

Abstract
Many orthopedic and surgical oncologists use a multidisciplinary approach to soft tissue sarcoma (STS) resection. This study assesses the role of immediate plastic surgeon involvement during index soft tissue sarcoma resection. Methods Adult patients who underwent index STS resection between 2005 and 2018 were queried from an institutional database. Main outcomes analyzed were 90-day same-site reoperation, any-cause readmission, and wound healing complications. Univariate and multivariate logistic regression were used to identify risk factors. Additional evaluation was then performed for the following two cohorts: patients with and without plastic surgeon involvement. Results In total, 228 cases were analyzed. Multivariate regression demonstrated the following predictors for 90-day wound-healing complications: plastic surgery intervention [OR = 0.321 (0.141-0.728), P = 0.007], operative time [OR = 1.003 (1.000-1.006), P = 0.039], and hospital length of stay [OR = 1.195 (1.004-1.367), P = 0.010]. For 90-day readmission, operative time [OR = 1.004 (1.001-1.007), P = 0.023] and tumor stage [OR = 1.966 (1.140-3.389), P = 0.015] emerged as multivariate predictors. Patients whose resection included a plastic surgeon experienced similar primary outcomes despite these patients having expectedly longer operative times (220 ± 182 versus 108 ± 67 minutes, P < 0.001) and hospital length of stay (3.99 ± 3.69 versus 1.36 ± 1.97 days, P < 0.001). Conclusions Plastic surgeon involvement emerged as a significant protector against 90-day wound healing complications. Cases that included plastic surgeons achieved similar complication rates in all categories relative to cases without plastic surgery intervention, despite greater operative time, hospital length of stay, and medical complications.

Abstract
Introduction The management of degenerative spine pathology continues to be a significant source of costs to the US healthcare system. Besides surgery, utilization of healthcare resources after spine surgery drives costs. The responsibility of managing costs is gradually shifting to patients and providers. Patient-centered predictors of healthcare utilization after elective spine surgery may identify targets for cost reduction and value creation. Therefore, our study aims to quantify patterns of healthcare utilization and identify risk factors that predict high healthcare utilization after elective spine surgery. Methods A total of 623 patients who underwent elective spine surgery at a tertiary academic medical center by one of three fellowship-trained orthopedic spine surgeons between 2013 and 2018 were identified in this retrospective cohort study. Healthcare utilization was quantified including advanced spine imaging, emergency and urgent care visits, hospital readmission, reoperation, PT/OT referrals, opioid prescriptions, epidural steroid injections, and pain management referrals. Patient variables, namely, the Charlson comorbidity index (CCI) and the American Society of Anesthesiologists (ASA) classification system, were assessed as potential predictors for healthcare utilization. Results Among all patients, a wide range of health utilization was identified. Age, body mass index, Charlson Comorbidity Index, and American Society of Anesthesiology class were identified as positive predictors of postoperative healthcare utilization including emergency department visits, spine imaging studies, opioid and nerve blocker prescriptions, inpatient rehabilitation, any referrals, and pain management referrals. Conclusions Markers of patient health-such as CCI and ASA class-may be used to predict healthcare utilization following elective spine surgery. Identifying at-risk patients and addressing these challenges prior to surgery is an important step to deliver efficient postoperative care. Level of Evidence 3.

Abstract
PURPOSE Although there has been substantial improvement in ACL reconstructive surgery, graft failure remains a devastating complication for some patients. Revision procedures are inherently more complex and technically challenging. The purpose of this study is to determine the incidence of short-term complications after these procedures and to compare trends in operative length, relative valuation, and reimbursement after primary versus revision ACL reconstruction. METHODS Primary and revision arthroscopic ACL reconstruction cases were identified on the American College of Surgeons' NSQIP database using Current Procedural Terminology (CPT) and International Classification of Diseases (ICD) codes between January 1, 2012 and December 31, 2017. Demographics, patient variables, and surgical variables were compared between primary and revision groups using Chi-squared tests. Logistic regression was used to identify independent risk factors for revision ACL reconstruction. Various 30-day outcome measures were compared between the primary and revision ACL reconstruction groups. Various measures of valuation-including total relative value units (RVU) and reimbursement per minute-were calculated and compared between the two groups. RESULTS A total of 8292 patients-8135 primary and 157 revision procedures-were included in the final cohort. Higher ASA scores were associated with revision ACL reconstructions. Patients undergoing revision procedures were less likely to have an ASA score of 1 (p < 0.001) and more likely to have an ASA score of 2 (p = 0.004) or 3 (p = 0.020). Revision ACL reconstruction was associated with higher rates of poor 30-day outcome measures, including unplanned readmission (p = 0.029), reoperation (p = 0.012), return to the OR (p = 0.012), and surgical complications (p = 0.021). The total RVUs and reimbursement for revision procedures were significantly greater than those for primary procedures (p < 0.001). However, when accounting for operative time, the RVU/minute and reimbursement/minute were similar between the two groups (n.s.). CONCLUSIONS Relative to primary ACL reconstruction, revision ACL procedures are associated with worse short-term outcomes-including unplanned readmission, reoperation, return to the OR, and surgical complications. A greater ASA score was independently predictive of revision ACL surgery. The current RVU system undervalues revision ACL procedures, considering the increased operative time and complexity of such procedures. LEVEL OF EVIDENCE Level III.

Abstract
Objective The importance of online information in the form of residency program websites has been well documented. With the rise of popularity of social media, another potential vital source of online information distribution exists. We aimed to examine the changes in orthopaedic surgery residency program websites and determine the use of social media by these programs. Methods A list of orthopaedic residency programs was obtained. Websites were then assessed for presence of numerous criteria. The presence of a social media account on Instagram, Twitter, and Facebook platforms was then determined. Results One hundred ninety-five websites out of 197 programs were identified. The most commonly present criterion was resident rotation schedule with 187 (96%) listings. Meanwhile, information on virtual sessions for prospective applicants was the least present at 26 (13%). Out of the 33 criteria assessed, websites contained an average of 20.4 criteria. Approximately half of the programs were noted to have a social media presence. Conclusion Website utilization and accessibility have improved over time as the importance of online information has continued to grow in the orthopaedic surgery residency application process. In order to increase their online presence, numerous programs have recently created or enhanced the profiles on social media platforms which may reach more users than websites alone.

Abstract
INTRODUCTION Radial head arthroplasty and open reduction internal fixation are two commonly utilized treatment options for radial head fractures. The purpose of this study is to assess the incidence of and risk factors for short-term complications following radial head arthroplasty and open reduction internal fixation of radial head fractures. METHODS The American College of Surgeons National Surgical Quality Improvement Program was queried to identify patients that underwent radial head arthroplasty or open reduction internal fixation for radial head fractures between January 1st, 2015 and December 31st, 2017. The incidence of various 30-day complications, including unplanned readmission, reoperation, non-home discharge, mortality, surgical/medical complications, and extended length-of-stay were compared between the two propensity matched groups. Multivariate logistic regression was used to identify independent risk factors for various short-term complications. RESULTS After propensity matching, a total of 435 patients were included in our analysis. 250 patients underwent radial head arthroplasty, and 185 patients underwent open reduction internal fixation. Arthroplasty treated patients had a significantly longer mean total operative time (p = .031) and length-of-stay (p = .003). No significant 30-day complications differences were found for unplanned readmission, reoperation, non-home discharge, mortality, surgical complications or medical complications. Independent risk factors for any complications of both procedures included a history of chronic obstructive pulmonary disease and American Society of Anesthesiologists class III. Significant risk factors for length-of-stay greater than two days included a history of bleeding disorder and American Society of Anesthesiologists class III. CONCLUSION Our study revealed there were no significant differences in 30-day perioperative surgical or medical complications from either surgical treatment of radial head fractures; however, radial head arthroplasty treated patients were met with a significantly longer length-of-stay and longer duration of operating time. We also identified risk factors that were independently associated with higher rates of complications regardless of treatment type.

Abstract
Background Distal biceps rupture is a relatively uncommon injury that can significantly affect quality of life. Early complications following biceps tendon repair are not well described in the literature. This study utilizes a national surgical database to determine the incidence of and predictors for short-term complications following distal biceps tendon repair. Methods The American College of Surgeons’ National Surgical Quality Improvement Program database was used to identify patients undergoing distal biceps repair between January 1, 2011, and December 31, 2017. Patient demographic variables of sex, age, body mass index, American Society of Anesthesiologists class, functional status, and several comorbidities were collected for each patient, along with 30-day postoperative complications. Binary logistic regression was used to calculate risk ratios for these complications using patient predictor variables. Results Early postoperative surgical complications (0.5%)—which were mostly infections (0.4%)—and medical complications (0.3%) were rare. A readmission risk factor was diabetes (risk ratio [RR], 4.238; 95% confidence interval [CI], 1.180–15.218). Non-home discharge risk factors were smoking (RR, 3.006; 95% CI, 1.123–8.044) and ≥60 years of age (RR, 4.150; 95% CI, 1.611– 10.686). Maleness was protective for medical complications (RR, 0.024; 95% CI, 0.005–0.126). Surgical complication risk factors were obese class II (RR, 4.120; 95% CI, 1.123–15.120), chronic obstructive pulmonary disease (COPD; RR, 21.981; 95% CI, 3.719–129.924), and inpatient surgery (RR, 8.606; 95% CI, 2.266–32.689). Conclusions Complication rates after distal biceps repair are low. Various patient demographics, medical comorbidities, and surgical factors were all predictive of short-term complications.

Abstract
Objective To summarize the main findings from research on measuring the value in spine surgery. Summary of Background Data Determining the value of surgical interventions, which is defined by the quality and efficacy of care received divided by the cost to deliver healthcare, is inherently complex. The two most fundamental components of value-quality and total cost-are multifactorial and difficult to quantify. Methods A narrative review of all the relevant papers known to the author was conducted. Results It is straightforward to calculate the aggregate hospital cost following a surgical procedure, but it is not simple to estimate the total cost of a procedure-including the direct and indirect costs. These individual metrics can help providers make more educated decisions with regards to improving patient quality of life and minimizing unnecessary costs. A consensus of the appropriate cost-per-quality-adjusted life-year threshold of different spine surgeries needs to be established. As these metrics become more commonplace in spine surgery, the potential for personalized health care will continue to be developed. Conclusions As the healthcare system shifts toward value-based care, there is a substantial need for research assessing the value as defined by the quality and efficacy of care received divided by the cost to deliver healthcare of specific spine surgery procedures. Studies on different predictors-both patient-specific and surgical-that may influence outcomes, cost, and value are required.

Abstract
INTRODUCTION Local steroid administration during anterior cervical spine surgery has been shown to improve postoperative dysphagia. However, concerns over potential complications remain. This study aims to evaluate the effect of local steroid administration on bone regeneration and spine fusion in a preclinical model, as well as the impact on osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hBM-MSCs) in a 3D culture system. MATERIALS AND METHODS Forty-five rats underwent bilateral L4-L5 posterolateral lumbar fusion (PLF) utilizing local delivery of low-dose recombinant human bone morphogenetic protein-2 (rhBMP-2; 0.5 μg/implant). Rats were divided into three groups: no steroid (control), low dose (0.5 mg/kg), and high dose (2.5 mg/kg) of triamcinolone. Bone growth and fusion were assessed using radiography, blinded manual palpation, and micro-CT analysis and were visualized by histology. The impact of triamcinolone exposure on osteogenic differentiation of hBM-MSCs was evaluated by gene expression analysis, alkaline phosphatase activity assay, and alizarin red staining. RESULTS No significant differences in fusion scores or rates were seen in the low- or high-dose steroid treatment groups relative to untreated controls. Quantification of new bone formation via micro-CT imaging revealed no significant between-group differences in the volume of newly regenerated bone. Triamcinolone also had no negative impact on pro-osteogenic gene transcript levels, and ALP activity was enhanced in the presence of triamcinolone. Mineral deposition appeared comparable in cultures grown with and without triamcinolone. CONCLUSIONS Local steroid application does not seem to inhibit rhBMP-2-mediated spine fusion in rats, though our study may not be adequately powered to detect differences in fusion as measured by manual palpation or bone volume as measured by micro-CT. These findings suggest that local triamcinolone may not increase pseudarthrosis in spine fusion procedures. Further large animal and clinical studies to verify its safety and efficacy are warranted.

Abstract
The purpose of this study was to examine current literature regarding the efficacy of total knee arthroplasty for patients with rheumatoid arthritis. Studies that assessed total knee arthroplasty outcomes in patients with rheumatoid arthritis were identified on MEDLINE from January 2009 to November 2018. All 4 studies that assessed knee pain and 9 of 11 studies that assessed knee function noted significant improvement in average knee score. However, between 10% and 47% of patients had significant knee pain at final follow-up. Total knee arthroplasty provides significant improvement in knee pain and function for patients with rheumatoid arthritis. However, the rates of postoperative pain vary widely.

Abstract
BACKGROUND CONTEXT The North American Spine Society (NASS) spine fellowship directory is an established resource that provides applicants with access to important information about different fellowship programs. Additionally, some programs have created websites to provide information about their fellowship program. There has been limited research on the amount and breadth of information provided by these different resources. PURPOSE To assess and compare the scope of information provided by the North American Spine Society (NASS) fellowship directory and individual fellowship program websites. STUDY DESIGN/SETTING Web Content Accessibility Study. PATIENT SAMPLE There were no patient data used in this study. All reported data were accessed from public websites and the NASS fellowship directory (August 2022 fellowships). OUTCOME MEASURES Outcome measures were reported as the presence or lack thereof of 22 topics pertaining to the specifics of each individual spine fellowship program on both the NASS fellowship directory and individual fellowship program websites. METHODS The NASS fellowship directory (August 2022 fellowships) and individual program websites were evaluated by two independent reviewers. Program websites were identified via Google search with a systematic protocol. Within each platform, the availability of various data were recorded. Twenty-four different data points were assessed for each program and were categorized into four main categories-general program information, fellow profiles, clinical roles, and nonclinical roles of the fellow. Chi-squared tests were used to compare differences in the availability of specific data provided by the NASS fellowship directory and individual program websites. RESULTS Seventy-four fellowship programs were identified. The NASS fellowship directory was more likely to provide information about the application process, a description of the program, fellow salary, faculty members, case descriptions, and research requirements (p<.05). The program websites were more likely to provide information about current and previous fellows-including a list of current fellow(s), their education/training, and a list of the previous fellows and their job choice (p<.05). Program websites were also more likely to discuss rotation schedules, clinic expectations, research opportunities, journal club, institutional meetings, sponsored national meetings, and current/previous research (p<.05). However, certain information, including specific clinical responsibilities (eg, rotation schedule, call expectations, clinic expectations) and the profiles of current and previous fellows, were not well represented on either platform. CONCLUSIONS There were significant differences in the type of information provided by the NASS fellowship directory and program websites. Furthermore, there were key pieces of information that were not well represented on either platform.

Abstract
Introduction Studies have shown that the use of total shoulder arthroplasty is increasing every year in the United Stated at a rate higher than that of total hip or total knee arthroplasty. As the population of the United States continues to age, it is becoming more important for surgeons to understand the true impact of age on outcomes and complications following procedures such a total shoulder arthroplasty. The purpose of this study was to determine if octogenarians have poorer outcomes after total shoulder arthroplasty compared to a younger, matched control group. Methods Data was obtained through the American College of Surgeons National Surgical Quality Improvement Program database (ACS NSQIP). Patients who had undergone total shoulder arthroplasty were identified by Current Procedural Terminology code (23472). Indication for arthroplasty was determined by ICD9/10 code (osteoarthritis, fracture, other). Each octogenarian was matched 1:1 to a non-octogenarian based on sex, BMI, ASA class, medical comorbidities, functional status, and surgical indication for arthroplasty by propensity scoring. A subgroup analysis was performed to compare outcomes between only those patients who underwent TSA for osteoarthritis.Outcomes of interest were assessed between the two groups for statistical significance using a chi-squared test or fisher exact test for expected values of less than 5. Statistical significance was set at p<0.05. Results After matching, octogenarians were found to be at higher risk of readmission (4.7% vs. 3.3%, p=0.046), non-home discharge (27.1% vs. 9.4%, p<0.001), and overall surgical (4.4% vs. 2.5%, p=0.006) and medical complications (3.7% vs. 2.4%, p=0.039). In the setting of TSA for osteoarthritis only, however, octogenarians were only at higher risk for non-home discharge (22.4% vs. 7.5%, p<0.001). Conclusions Octogenarians are at higher risk of some complications following total shoulder arthroplasty but fewer than has been previously reported, particularly in the setting of arthroplasty for the treatment of arthritis.

Abstract
We recently developed a recombinant growth factor-free bone regenerative scaffold composed of stoichiometric hydroxyapatite (HA) ceramic particles and human demineralized bone matrix (DBM) particles (HA-DBM). Here, we performed the first pre-clinical comparative evaluation of HA-DBM relative to the industry standard and established positive control, recombinant human bone morphogenetic protein-2 (rhBMP-2), using a rat posterolateral spinal fusion model (PLF). Female Sprague-Dawley rats underwent bilateral L4-L5 PLF with implantation of the HA-DBM scaffold or rhBMP-2. Fusion was evaluated using radiography and blinded manual palpation, while biomechanical testing quantified the segmental flexion-extension range-of-motion (ROM) and stiffness of the fused segments at 8-weeks postoperatively. For mechanistic studies, pro-osteogenic gene and protein expression at 2-days and 1-, 2-, and 8-weeks postoperatively was assessed with another cohort. Unilateral fusion rates did not differ between the HA-DBM (93%) and rhBMP-2 (100%) groups; however, fusion scores were higher with rhBMP-2 (p = 0.008). Both treatments resulted in significantly reduced segmental ROM (p < 0.001) and greater stiffness (p = 0.009) when compared with non-operated controls; however, the degree of stabilization was significantly higher with rhBMP-2 treatment relative to the HA-DBM scaffold. In the mechanistic studies, PLGA and HA scaffolds were used as negative controls. Both rhBMP-2 and HA-DBM treatments resulted in significant elevations of several osteogenesis-associated genes, including Runx2, Osx, and Alp. The rhBMP-2 treatment led to significantly greater early, mid, and late osteogenic markers, which may be the mechanism in which early clinical complications are seen. The HA-DBM scaffold also induced osteogenic gene expression, but primarily at the 2-week postoperative timepoint. Overall, our findings show promise for this 3D-printed composite as a recombinant growth factor-free bone graft substitute for spinal fusion. STATEMENT OF SIGNIFICANCE: Despite current developments in bone graft technology, there remains a significant void in adequate materials for bone regeneration in clinical applications. Two of the most efficacious bone graft options are the gold-standard iliac crest bone graft and recombinant human-derived bone morphogenetic protein-2 (rhBMP-2), available commercially as Infuse™. Although efficacious, autologous graft is associated with donor-site morbidity, and Infuse™ has known side effects related to its substantial host inflammatory response, possibly associated with a immediate, robust osteoinductive response. Hence, there is a need for a bone graft substitute that provides adequate osteogenesis without associated adverse events. This study represents a significant step in the design of off-the-shelf growth factor-free devices for spine fusion.

Abstract
Historically, iliac crest bone autograft has been considered the gold standard bone graft substitute for spinal fusion. However, the significant morbidity associated with harvesting procedures has influenced decision-making and practice patterns. To minimize these side effects, many clinicians have pursued the use of bone graft extenders to minimize the amount of autograft required for fusion in certain applications. Synthetic materials, including a variety of ceramic compounds, are a class that has been studied extensively as bone graft extenders. These have been used in combination with a wide array of other biomaterials and investigated in a variety of different spine fusion procedures. This review will summarize the current evidence of different synthetic materials in various spinal fusion procedures and discuss the future of novel synthetics.

Abstract
This review article addresses the various aspects of nano-biomaterials used in or being pursued for the purpose of promoting bone regeneration. In the last decade, significant growth in the fields of polymer sciences, nanotechnology, and biotechnology has resulted in the development of new nano-biomaterials. These are extensively explored as drug delivery carriers and as implantable devices. At the interface of nanomaterials and biological systems, the organic and synthetic worlds have merged over the past two decades, forming a new scientific field incorporating nano-material design for biological applications. For this field to evolve, there is a need to understand the dynamic forces and molecular components that shape these interactions and influence function, while also considering safety. While there is still much to learn about the bio-physicochemical interactions at the interface, we are at a point where pockets of accumulated knowledge can provide a conceptual framework to guide further exploration and inform future product development. This review is intended as a resource for academics, scientists, and physicians working in the field of orthopedics and bone repair.

Abstract
Background Given the trend toward value-based care, there has been increased interest in minimizing hospital length of stay (LOS) after orthopedic procedures. Outpatient total ankle arthroplasty (TAA) has become more popular in recent years; however, research on surgical outcomes of this procedure has been limited. This study sought to employ large sample, propensity score-matched analyses to assess the safety of outpatient and short-stay discharge pathways following TAA. Methods The ACS NSQIP database was used to identify 1141 patients who underwent primary and revision TAA between 2007 and 2017. Propensity score matching was used to match patients based on several factors, including age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, and several comorbidities. The incidence of various 30-day complications was compared between the short and standard LOS groups to assess for any differences in short-term outcomes. Results A total of 892 patients were included in the final propensity score-matched analysis, with 446 patients in each group. The short LOS group had a significantly lower rate of medical complications (0.2% vs. 2.5%, p = 0.006) and non-home discharge (1.3% vs. 12.1%, p < 0.001). There was no significant difference in operative complications (0.4% vs. 1.8%, p = 0.107), unplanned readmission (0.4% vs. 1.1%, p = 0.451), reoperation (0.2% vs. 0.4%, p > 0.999), return to the OR (0.2% vs. 0.9%, p = 0.374), or mortality (0.7% vs. 0.0%, p > 0.249) between the short and standard LOS groups. Conclusions Outpatient and short-stay hospitalization had comparable safety to standard inpatient hospitalization after TAA. Outpatient or short-stay TAA should be considered for patients with low risk of short-term complications.

Abstract
PURPOSE OF REVIEW Biologic bone graft materials continue to be an important component of various spinal fusion procedures. Given the known risks and morbidity of harvesting iliac crest bone graft, the historical gold standard for spinal fusion, these biologic materials serve the purpose of improving both the efficacy and safety of spinal fusion procedures. Recent advances in biomedical and materials sciences have enabled the design of many novel materials that have shown promise as effective bone graft materials. This review will discuss current research pertaining to several of these materials, including functionalized peptide amphiphiles and other nanocomposites, novel demineralized bone matrix applications, 3D-printed materials, and Hyperelastic Bone®, among others. RECENT FINDINGS Recent investigation has demonstrated that novel technologies, including nanotechnology and 3D printing, can be used to produce biomaterials with significant osteogenic potential. Notably, peptide amphiphile nanomaterials functionalized to bind BMP-2 have demonstrated significant bone regenerative capacity in a pre-clinical rodent posterolateral lumbar fusion (PLF) model. Additionally, 3D-printed Hyperelastic Bone® has demonstrated promising bone regenerative capacity in several in vivo animal models. Composite materials such as TrioMatrix® (demineralized bone matrix, hydroxyapatite, and nanofiber-based collagen scaffold) have also demonstrated significant osteogenic potential in both in vitro and in vivo settings. Advances in materials science and engineering have allowed for the design and implementation of several novel biologic materials, including nanocomposites, 3D-printed materials, and various biologic composites. These materials provide significant bone regenerative capacity and have the potential to be alternatives to other bone graft materials, such as autograft and BMP-2, which have known complications.
