RESUMEN
BACKGROUND: Vertebral fractures are associated with enduring back pain, diminished quality of life, as well as increased morbidity and mortality. Existing epidemiological data for cervical and thoracic vertebral fractures are limited by insufficiently powered studies and a failure to evaluate the mechanism of injury. QUESTION/PURPOSE: What are the temporal trends in incidence, patient characteristics, and injury mechanisms of cervical and thoracic vertebral fractures in the United States from 2003 to 2021? METHODS: The United States National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP) database collects data on all nonfatal injuries treated in US hospital emergency departments and is well suited to capture epidemiological trends in vertebral fractures. As such, the NEISS-AIP was queried from 2003 to 2021 for cervical and thoracic fractures. The initial search by upper trunk fractures yielded 156,669 injuries; 6% (9900) of injuries, with a weighted frequency of 638,999 patients, met the inclusion criteria. The mean age was 62 ± 25 years and 52% (334,746 of 638,999) of patients were females. Descriptive statistics were obtained. Segmented regression analysis, accounting for the year before or after 2019 when the NEISS sampling methodology was changed, was performed to assess yearly injury trends. Multivariable logistic regression models with age and sex as covariates were performed to predict injury location, mechanism, and disposition. RESULTS: The incidence of cervical and thoracic fractures increased from 2.0 (95% CI 1.4 to 2.7) and 3.6 (95% CI 2.4 to 4.7) per 10,000 person-years in 2003 to 14.5 (95% CI 10.9 to 18.2) and 19.9 (95% CI 14.5 to 25.3) in 2021, respectively. Incidence rates of cervical and thoracic fractures increased for all age groups from 2003 to 2021, with peak incidence and the highest rate of change in individuals 80 years or older. Most injuries occurred at home (median 69%), which were more likely to impact older individuals (median [range] age 75 [2 to 106] years) and females (median 61% of home injuries); injuries at recreation/sports facilities impacted younger individuals (median 32 [3 to 96] years) and male patients (median 76% of sports facility injuries). Falls were the most common injury mechanism across all years, with females more likely to be impacted than males. The proportion of admissions increased from 33% in 2003 to 50% in 2021, while the proportion of treated and released patients decreased from 53% to 35% in the same period. CONCLUSION: This epidemiological study identified a disproportionate increase in cervical and thoracic fracture incidence rates in patients older than 50 years from 2003 to 2021. Furthermore, high hospital admission rates were also noted resulting from these fractures. These findings indicate that current osteoporosis screening guidelines may be insufficient to capture the true population at risk of osteoporotic fractures, and they highlight the need to initiate screening at an earlier age. LEVEL OF EVIDENCE: Level III, prognostic study.
RESUMEN
PURPOSE: The number of patients with asymptomatic human immunodeficiency virus (AHIV) is increasing as the efficacy of antiretroviral therapy improves. While there is research on operative risks associated with having HIV, there is a lack of literature describing the impact of well-controlled HIV on postoperative complications. This study seeks to elucidate the impact of AHIV on postoperative outcomes after total hip (THA) and knee (TKA) arthroplasty. METHODS: The Nationwide Inpatient Sample was retrospectively reviewed for patients undergoing TKA and THA from 2005 to 2013. Subjects were subdivided into those with AHIV and those without HIV (non-HIV). Patient demographics, hospital-related parameters, and postoperative complications were all collected. One-to-one propensity score-matching, Chi-square analysis, and multivariate logistical regressions were performed to compare both cohorts. RESULTS: There were no significant differences between AHIV and non-HIV patients undergoing TKA or THA in terms of sex, age, insurance status, or total costs (all, p ≥ 0.081). AHIV patients had longer lengths of stay (4.0 days) than non-HIV patients after both TKA (3.3 days) and THA (3.1 days) (p ≤ 0.011). Both TKA groups had similar postoperative complication rates (p > 0.081). AHIV patients undergoing THA exhibited an increased rate of overall surgical complications compared non-HIV patients (0 vs. 4.5%, p = 0.043). AHIV was not associated with increased complications following both procedures. CONCLUSION: Despite lengthier hospital stays among AHIV patients, baseline AHIV was not associated with adverse outcomes following TKA and THA. This adds to the literature and warrants further research into the impact of asymptomatic, well-controlled HIV infection on postoperative outcomes following total joint arthroplasty.

STUDY DESIGN: Retrospective cohort study utilizing the New York statewide planning and research cooperative system. STUDY OBJECTIVE: To investigate postoperative complications of patients with metabolic bone disorders (MBDs) who undergo 2-3 levels of anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND DATA: MBDs and cervical degenerative pathologies, including cervical radiculopathy (CR) and cervical myelopathy (CM), are prevalent in the aging population. Complications with ACDF procedures can lead to increased hospitalization times, more expensive overhead, and worse patient outcomes. METHOD: Patients with CM/CR who underwent an ACDF of 2-3 vertebrae from 2009 to 2011 with a minimum 2-year follow-up were identified. Patients diagnosed with 1 or more MBD at baseline were compared with a control cohort without any MBD diagnosis. Cohorts were compared for demographics, hospital-related parameters, and 2-year medical, surgical, and overall complications. Binary multivariate logistic regression was used to identify independent predictors. RESULTS: A total of 22,276 patients were identified (MBD: 214; no-MBD: 22,062). Among MBD patients, the majority had vitamin D deficiency (n = 194, 90.7%). MBD patients were older (53.0 vs 49.7 y, P < 0.001), and with higher Deyo index (1.0 vs 0.5, P < 0.001). MBD patients had higher rates of medical complications, including anemia (6.1% vs 2.3%), pneumonia (4.7% vs 2.1%), hematoma (3.3% vs 0.7%), infection (2.8% vs 0.9%), and sepsis (3.7% vs 0.9%), as well as overall medical complications (23.8% vs 9.6%) (all, P ≤0.033). MBD patients also experienced higher surgical complications, including implant-related (5.7% vs 1.9%), wound infection (4.2% vs 1.2%), and wound disruption (0.9% vs 0.2%), and overall surgical complications (9.8% vs 3.2%) (all, P ≤0.039). Regression analysis revealed that a baseline diagnosis of MBD was independently associated with an increased risk of 2-year surgical complications (odds ratio = 2.10, P < 0.001) and medical complications (odds ratio = 1.84, P = 0.001). CONCLUSIONS: MBD as a comorbidity was associated with an increased risk of 2-year postoperative complications after 2-3 level ACDF for CR or CM.

Understanding global body balance can optimize the postoperative course for patients undergoing spinal or lower limb surgical realignment. This observational cohort study aimed to characterize patients with reported imbalance and identify predictors. The CDC establishes a representative sample annually via the NHANES. All participants who said "yes" (Imbalanced) or "no" (Balanced) to the following question were identified from 1999-2004: "During the past 12 months, have you had dizziness, difficulty with balance or difficulty with falling?" Univariate analyses compared Imbalanced versus Balanced subjects and binary logistic regression modeling predicted for Imbalance. Of 9964 patients, imbalanced (26.5%) were older (65.4 vs. 60.6 years), with more females (60% vs. 48%). Imbalanced subjects reported higher rates of comorbidities, including osteoporosis (14.4% vs. 6.6%), arthritis (51.6% vs. 31.9%), and low back pain (54.4% vs 32.7%). Imbalanced patients had more difficulty with activities, including climbing 10 steps (43.8% vs. 21%) and stooping/crouching/kneeling (74.3% vs. 44.7%), and they needed greater time to walk 20 feet (9.5 vs. 7.1 s). Imbalanced subjects had significantly lower caloric and dietary intake. Regression revealed that difficulties using fingers to grasp small objects (OR: 1.73), female gender (OR: 1.43), difficulties with prolonged standing (OR: 1.29), difficulties stooping/crouching/kneeling (OR: 1.28), and increased time to walk 20 feet (OR: 1.06) were independent predictors of Imbalance (all p < 0.05). Imbalanced patients were found to have identifiable comorbidities and were detectable using simple functional assessments. Structured tests that assess dynamic functional status may be useful for preoperative optimization and risk-stratification for patients undergoing spinal or lower limb surgical realignment.
RESUMEN
PURPOSE: While bone health is instrumental in orthopedic surgery, few studies have described the long-term outcomes of osteoporosis (OP) in patients undergoing total hip (THA) or knee (TKA) arthroplasties. METHODS: Using the New York State statewide planning and research cooperative system database, all patients who underwent primary TKA or THA for osteoarthritis from 2009 to 2011 with minimum 2-year follow-up were identified. They were divided based on their OP status (OP and non-OP) and 1:1 propensity score matched for age, sex, race, and Charlson/Deyo index. Cohorts were compared for demographics, hospital-related parameters, and 2-year postoperative complications and reoperations. Multivariate binary logistic regression was utilized to identify significant independent associations with 2-year medical and surgical complications and revisions. RESULTS: A total of 11,288 TKA and 8248 THA patients were identified. OP and non-OP TKA patients incurred comparable overall hospital charges for their surgical visit and hospital length of stay (LOS) (both, p ≥ 0.125). Though OP and non-OP THA patients incurred similar mean hospital charges for their surgical visit, they experienced longer hospital LOS (4.3 vs. 4.1 days, p = 0.035). For both TKA and THA, OP patients had higher rates of overall and individual medical and surgical complications (all, p < 0.05). OP was independently associated with the 2-year occurrence of any overall, surgical, and medical complications, and any revision in TKA and THA patients (all, OR ≥ 1.42, p < 0.001). CONCLUSION: Our study found OP was associated with a greater risk of 2-year adverse outcomes following TKA or THA, including medical, surgical, and overall complications as well as revision operations compared to non-OP patients.

In the United States, nearly 1.2 million people > 12 years old have human immunodeficiency virus (HIV), which is associated with postoperative complications following orthopedic procedures. Little is known about how asymptomatic HIV (AHIV) patients fare postoperatively. This study compares complications after common spine surgeries between patients with and without AHIV. The Nationwide Inpatient Sample (NIS) was retrospectively reviewed from 2005-2013, identifying patients aged > 18 years who underwent 2-3-level anterior cervical discectomy and fusion (ACDF), ≥4-level thoracolumbar fusion (TLF), or 2-3-level lumbar fusion (LF). Patients with AHIV and without HIV were 1:1 propensity score-matched. Univariate analysis and multivariable binary logistic regression were performed to assess associations between HIV status and outcomes by cohort. 2-3-level ACDF (n = 594 total patients) and ≥4-level TLF (n = 86 total patients) cohorts demonstrated comparable length of stay (LOS), rates of wound-related, implant-related, medical, surgical, and overall complications between AHIV and controls. 2-3-level LF (n = 570 total patients) cohorts had comparable LOS, implant-related, medical, surgical, and overall complications. AHIV patients experienced higher postoperative respiratory complications (4.3% vs. 0.4%,). AHIV was not associated with higher risks of medical, surgical, or overall inpatient postoperative complications following most spine surgical procedures. The results suggest the postoperative course may be improved in patients with baseline control of HIV infection.
RESUMEN
Background: Upper extremity (UE) microsurgical reconstruction relies upon proper wound healing for optimal outcomes. Cigarette smoking is associated with wound healing complications, yet conclusions vary regarding impact on microsurgical outcomes (replantation, revascularization, and free tissue transfer). We investigated how smoking impacted 30-day standardized postoperative outcomes following UE microsurgical reconstruction. Methods: Utilizing the National Surgical Quality Improvement Program, all patients who underwent (1) UE free flap transfer (n = 70) and (2) replantation/revascularization (n = 270) were identified. For each procedure, patients were stratified by recent smoking history (current smoker ≤1-year preoperatively). Baseline demographics and standardized 30-day complications, reoperations, and readmissions were compared between smokers and nonsmokers. Results: Replantation/revascularization patients had no differences in sex, race, or body mass index between smokers (n = 77) and nonsmokers. Smokers had a higher prevalence of congestive heart failure (5.2% vs 1.0%, P = .036) and nonsmokers were more often on hemodialysis (15.6% vs 10.4%, P = .030). Free flap transfer patients had no differences in age, sex, or race between smokers (n = 14) and nonsmokers. Smokers had a longer length of stay (6.6 vs 4.2 days, P = .001) and a greater prevalence of chronic obstructive pulmonary disorder (COPD; 7.1% vs 0%, P = .044). Recent smoking was not associated with increased odds of any 30-day minor and major standardized surgical complications, readmissions, or reoperations following UE microsurgical reconstruction via free flap transfer or replantation/revascularization. Baseline diagnosis of COPD was also not a predictor of adverse 30-day outcomes following free flap transfer. Conclusion: Recent smoking history was not associated with any 30-day adverse outcomes following UE microsurgical reconstruction via replantation/revascularization or free flap transfer. In light of these findings, further investigation is warranted, with particular focus on adverse events specific to free flaps and replantation/revascularization.
Contexte: La reconstruction microchirurgicale du membre supérieur repose sur la bonne guérison de la plaie pour des résultats optimaux. Le tabagisme est associé à des complications pour la guérison des plaies; toutefois, les conclusions concernant ses répercussions sur les résultats microchirurgicaux (réimplantation, revascularisation et transfert de tissu libre) sont variables. Nous avons cherché à savoir quelles étaient les répercussions du tabagisme sur les résultats postopératoires standardisés à 30 jours après reconstruction microchirurgicale du membre supérieur. Méthodes: Utilisant le Programme national d'amélioration de la qualité de la chirurgie, tous les patients ayant subi (1) un transfert de lambeau libre du membre supérieur (n = 70) et (2) une réimplantation/revascularisation (n = 270) ont été identifiés. Pour chaque procédure, les patients ont été classés en fonction de leurs antécédents de tabagisme récent (fumeur actuel ≤ 1 an préopératoire). Les données démographiques initiales et les complications standardisées à 30 jours, les réinterventions et les réhospitalisations ont été comparées entre fumeurs et non-fumeurs. Résultats: Concernant les réimplantations/revascularisations, il n'y a pas eu de différences en termes de sexe, race ou IMC entre les fumeurs (n = 77) et les non-fumeurs. Les fumeurs avaient une plus grande prévalence d'insuffisance cardiaque congestive (5,2 % contre 1,0 %, P = 0,036) et les non-fumeurs étaient plus souvent sous hémodialyse (15,6 % contre 10,4 %, P = 0,030). Concernant les patients ayant eu un transfert de lambeau libre, il n'y a pas eu de différences en termes d'âge, de sexe ou de race entre les fumeurs (n = 14) et les non-fumeurs. La durée d'hospitalisation des fumeurs a été plus longue (6,6 jours contre 4,2 jours, P =0,001) avec une prévalence plus élevée de MPOC (7,1 % contre 0 %, P = 0,044). Le tabagisme récent n'a pas été associé à une augmentation de la probabilité de complications chirurgicales standardisées, majeures ou mineures, à 30 jours, de réhospitalisation ou reprises chirurgicales après reconstruction microchirurgicale du membre supérieur par transfert de lambeau libre ou réimplantation/revascularisation. Le diagnostic de MPOC à l'inclusion dans l'étude n'était pas non plus un facteur prédictif d'événements indésirables à 30 Jours après transfert de lambeau libre. Conclusion: Un antécédent de tabagisme récent n'a pas été associé à des résultats indésirables à 30 jours après reconstruction microchirurgicale du membre supérieur via réimplantation/revascularisation ou transfert de lambeau libre. À la lumière de ces constatations, des études supplémentaires portant particulièrement sur les événements indésirables propres aux procédures de lambeaux libres et de réimplantation/revascularisation sont justifiées.
RESUMEN
Prematurity is associated with surgical complications. This study sought to determine the risk of prematurity on 30-day complications, reoperations, and readmissions following ≥7-level PSF for AIS which has not been established. Utilizing the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP)-Pediatric dataset, all AIS patients undergoing ≥7-level PSF from 2012-2016 were identified. Cases were 1:1 propensity score-matched to controls by age, sex, and number of spinal levels fused. Prematurity sub-classifications were also evaluated: extremely (<28 weeks), very (28-31 weeks), and moderate-to-late (32-36 weeks) premature. Univariate analysis with post hoc Bonferroni compared demographics, hospital parameters, and 30-day outcomes. Multivariate logistic regression identified independent predictors of adverse 30-day outcomes. 5531 patients (term = 5099; moderate-to-late premature = 250; very premature = 101; extremely premature = 81) were included. Premature patients had higher baseline rates of multiple individual comorbidities, longer mean length of stay, and higher 30-day readmissions and infections than the term cohort. Thirty-day readmissions increased with increasing prematurity. Very premature birth predicted UTIs, superficial SSI/wound dehiscence, and any infection, and moderate-to-late premature birth predicted renal insufficiency, deep space infections, and any infection. Prematurity of AIS patients differentially impacted rates of 30-day adverse outcomes following ≥7-level PSF. These results can guide preoperative optimization and postoperative expectations.
RESUMEN
Background: The 5-factor modified frailty index (mFI-5) has been shown to be a concise and effective tool for predicting adverse events following various spine procedures. However, there have been no studies assessing its utility in patients undergoing anterior lumbar interbody fusion (ALIF). Therefore, the aim of this study was to analyze the predictive capabilities of the mFI-5 for 30-day postoperative adverse events following elective ALIF. Methods: The National Surgical Quality Improvement Program (NSQIP) database was queried from 2010 through 2019 to identify patients who underwent elective ALIF using Current Procedural Terminology (CPT) codes in patients over the age of 50. The mFI-5 score was calculated using variables for hypertension, congestive heart failure, comorbid diabetes, chronic obstructive pulmonary disease, and partially or fully dependent functional status which were each assigned 1 point. Univariate analysis and multivariate logistic regression models were utilized to identify the associations between mFI-5 scores, and 30-day rates of overall complications, readmissions, reoperations, and mortality. Results: 11,711 patients were included (mFI-5=0: 4,026 patients, mFI-5=1: 5,392, mFI-5=2: 2,102, mFI-5=3+: 187. Multivariate logistic regression revealed that mFI-5 scores of 1 (OR: 2.2, CI: 1.2-4.2, p=0.02), 2 (OR: 3.6, CI: 1.8-7.3, p<0.001), and 3+ (OR: 7.0, CI: 2.5-19.3, p<0.001) versus a score of 0 were significant predictors of pneumonia. An mFI-5 score of 2 (OR: 1.3; CI: 1.01-1.6, p=0.04), and 3+ (OR: 1.9; CI: 1.1-3.1; p=0.01) were both independent predictors of related readmissions. An mFI score of 3+ was an independent predictor of any complication (OR: 1.5, CI: 1.01-2.2, p=0.004), UTI (OR: 2.4, CI: 1.1-5.2, p=0.02), and unplanned intubation (OR: 4.5, CI: 1.3-16.1, p=0.02). Conclusions: The mFI-5 is an independent predictor for 30-day postoperative complications, readmissions, UTI, pneumonia, and unplanned intubations following elective ALIF surgery in adults over the age of 50.
RESUMEN
INTRODUCTION: Osteoporosis affects nearly 200 million individuals worldwide. Given this notable disease burden, there have been increased efforts to investigate complications in patients with osteoporosis undergoing cervical fusion (CF). However, there are limited data regarding long-term outcomes in osteoporotic patients in the setting of ≥4-level cervical fusion. METHODS: The New York State Statewide Planning and Research Cooperative System database was used to identify patients who underwent posterior or combined anterior-posterior ≥4-level CF for cervical radiculopathy or myelopathy from 2009 to 2011, with a minimum follow-up surveillance of 2 years. The following were compared between patients with and without osteoporosis: demographics, hospital-related parameters, medical/surgical complications, readmissions, and revisions. Binary multivariate stepwise logistic regression was used to identify independent predictors of outcomes. RESULTS: A total of 2,604 patients were included (osteoporosis: n = 136 (5.2%); nonosteoporosis: n = 2,468). Patients with osteoporosis were older (66.9 ± 11.2 vs. 60.0 ± 11.4 years, P < 0.001), more often female (75.7% vs. 36.2%, P < 0.001), and White (80.0% vs. 65.3%, P = 0.007). Both cohorts had comparable comorbidity burdens (Charlson/Deyo: 1.1 ± 1.2 vs. 1.0 ± 1.3, P = 0.262), total hospital charges ($100,953 ± 94,933 vs. $91,618 ± 78,327, P = 0.181), and length of stay (9.7 ± 10.4 vs. 8.4 ± 9.6 days, P = 0.109). Patients with osteoporosis incurred higher rates of overall medical complication rates (41.9% vs. 29.4%, P = 0.002) and individual surgical complications, such as nonunion (2.9% vs. 0.7%, P = 0.006). Osteoporosis was associated with medical complications (OR = 1.57, P = 0.021), surgical complications (OR = 1.52, P = 0.030), and readmissions (OR = 1.86, P = 0.003) at 2 years. DISCUSSION: Among patients who underwent multilevel cervical fusion, those with osteoporosis had higher risk of adverse postoperative outcomes at two years. These data indicate that preoperative screening and management of osteoporosis may be important for optimizing long-term outcomes in patients who require multilevel CF.

PURPOSE: Concerns persist that trainee participation in surgical procedures may compromise patient care and potentiate adverse events and costs. We aimed to analyse the potential impact and consequences of surgical trainee involvement in total hip arthroplasty (THA) procedures in terms of surgical efficacy, patient safety, and functional outcomes. METHODS: We systematically reviewed Medline/PubMed, EMBASE, the Cochrane library, and Scopus databases in October 2021. Eligible studies reported a direct comparison between THA cases performed with and without trainee involvement. RESULTS: Eighteen publications met our eligibility criteria and were included in our study. The included studies reported on 142,450 THAs completed on 142,417 patients. Specifically, 48,155 and 94,295 surgeries were completed with and without trainee involvement, respectively. The mean operative times for procedures with (n = 5,662) and without (n = 14,763) trainee involvement were 106.20 and 91.41 min, respectively. Mean overall complication rates were 6.43% and 5.93% for THAs performed with (n = 4842) and without (n = 12,731) trainees. Lastly, the mean Harris Hip Scores (HHS) for THAs performed with (n = 442) and without (n = 750) trainee participation were 89.61 and 86.97, respectively. CONCLUSION: Our systematic review confirmed previous studies' reports of increased operative time for THA cases with trainee involvement. However, based on the overall similar complication rates and functional hip scores obtained, patients should be reassured concerning the relative safety of trainee involvement in THA. Future prospective studies with higher levels of evidence are still needed to reinforce the existing evidence.

PURPOSE: Trainee involvement in patient care has raised concerns about the potential risk of adverse outcomes and harming patients. We sought to analyze the impact and potential consequence of surgical trainee involvement in total knee arthroplasty (TKA) procedures in terms of surgical efficacy, patient safety, and functional outcomes. METHODS: We systematically reviewed Medline/PubMed, EMBASE, the Cochrane library, and Scopus databases in April 2021. Eligible studies reported on the impact of trainee participation in TKA procedures performed with and without such involvement. RESULTS: Twenty-three publications met our eligibility criteria and were included in our study. These studies reported on 132,624 surgeries completed on 132,416 patients. Specifically, 23,988 and 108,636 TKAs were performed with and without trainee involvement, respectively. The mean operative times for procedures with (n = 19,573) and without (n = 94,581) trainee involvement were 99.77 and 85.05 min, respectively. Both studies that reported data on cost of TKAs indicated a significant increase (p < 0.001) associated with procedures completed by teaching hospitals compared to private practices. Mean overall complication rates were 7.20% and 7.36% for TKAs performed with (n = 9,386) and without (n = 31,406) trainees. Lastly, the mean Knee Society Scale (KSS) knee scores for TKAs with (n = 478) and without (n = 806) trainee involvement were similar; 82.81 and 82.71, respectively. CONCLUSION: Our systematic review concurred with previous studies that reported trainee involvement during TKAs increases the mean operative time. However, the overall complication rates and functional outcomes were similar. Larger studies with a better methodology and higher level of evidence are still needed for a resolute conclusion.

Background: Cannabis is the most commonly used recreational drug in the USA. Studies evaluating cannabis use and its impact on outcomes following cervical spinal fusion (CF) are limited. This study sought to assess the impact of isolated (exclusive) cannabis use on postoperative outcomes following CF by analyzing outcomes like complications, readmissions, and revisions. Methods: The New York Statewide Planning and Research Cooperative System (SPARCS) was queried for patients who underwent CF between January 2009 and September 2013. Inclusion criteria were age ≥18 years and either a minimum 90-day (for complications and readmissions) or 2-year (for revisions) follow-up surveillance. Patients with systemic disease, osteomyelitis, cancer, trauma, and concomitant substance or polysubstance abuse/dependence were excluded. Patients with a preoperative International Classification of Diseases, 9th Edition, Clinical Modification (ICD-9-CM) diagnosis of isolated cannabis abuse (Cannabis) or dependence were identified. The primary outcome measures were 90-day complications, 90-day readmissions, and two-year revisions following CF. Cannabis patients were 1:1 propensity score-matched by age, gender, race, Deyo score, surgical approach, and tobacco use to non-cannabis users and compared for outcomes. Multivariate binary stepwise logistic regression models identified independent predictors of outcomes. Results: 432 patients (n=216 each) with comparable age, sex, Deyo scores, tobacco use, and distribution of anterior or posterior surgical approaches were identified (all p>0.05). Cannabis patients were predominantly Black (27.8% vs. 12.0%), primarily utilized Medicaid (29.6% vs. 12.5%), and had longer LOS (3.0 vs. 1.9 days), all p≤0.001. Both cohorts experienced comparable rates of 90-day medical and surgical, as well as overall complications (5.6% vs. 3.7%) and two-year revisions (4.2% vs. 2.8%, p=0.430), but isolated cannabis patients had higher 90-day readmission rates (11.6% vs. 6.0%, p=0.042). Isolated cannabis use independently predicted 90-day readmission (Odds Ratio=2.0), but did not predict any 90-day complications or two year revisions (all p>0.05). Conclusion: Isolated baseline cannabis dependence/abuse was associated with increased risk of 90-day readmission following CF. Further investigation of the physiologic impact of cannabis on musculoskeletal patients may elucidate significant contributory factors. Level of Evidence: III.

Introduction We evaluated the demographics, flap types, and 30-day complication, readmission, and reoperation rates for upper extremity free flap transfers within the National Surgical Quality Improvement Program (NSQIP) database. Materials and Methods Upper extremity free flap transfer patients in the NSQIP from 2008 to 2016 were identified. Complications, reoperations, and readmissions were queried. Chi-squared tests evaluated differences in sex, race, and insurance. The types of procedures performed, complication frequencies, reoperation rates, and readmission rates were analyzed. Results One-hundred-eleven patients were selected (mean: 36.8 years). Most common upper extremity free flaps were muscle/myocutaneous (45.9%) and other vascularized bone grafts with microanastomosis (27.9%). Thirty-day complications among all patients included superficial site infections (2.7%), intraoperative transfusions (7.2%), pneumonia (0.9%), and deep venous thrombosis (0.9%). Thirty-day reoperation and readmission rates were 4.5% and 3.6%, respectively. The mean time from discharge to readmission was 12.5 days. Conclusion Upper extremity free flap transfers could be performed with a low rate of 30-day complications, reoperations, and readmissions.
RESUMEN
BACKGROUND: There is limited research regarding the association between the mFI-5 and postoperative complications among adult spinal deformity (ASD) patients. METHODS: Using the National Surgical Quality Improvement Project (NSQIP) database, patients with Current Procedural Terminology (CPT) codes for > 7-level fusion or < 7-level fusion with International Classification of Diseases, Ninth Revision (ICD-9) codes for ASD were identified between 2008 and 2016. Univariate analyses with post-hoc Bonferroni correction for demographics and preoperative factors were performed. Logistic regression assessed associations between mFI-5 scores and 30-day post-operative outcomes. RESULTS: 2,120 patients met criteria. Patients with an mFI-5 score of 4 or 5 were excluded, given there were<20 patients with those scores. Patients with mFI-5 scores of 1 and 2 had increased 30-day rates of pneumonia (3.5 % and 4.3 % vs 1.6 %), unplanned postoperative ventilation for > 48 h (3.1 % and 4.3 % vs 0.9 %), and UTIs (4.4 % and 7.4 % vs 2.0 %) than patients with a score of 0 (all, p < 0.05). Logistic regression revealed that compared to an mFI-5 of 0, a score of 1 was an independent predictor of 30-day reoperations (OR = 1.4; 95 % CI 1.1-18). A score of 2 was an independent predictor of overall (OR = 2.4; 95 % CI 1.4-4.1) and related (OR = 2.2; 95 % CI 1.2-4.1) 30-day readmissions. A score of 3 was not predictive of any adverse outcome. CONCLUSION: The mFI-5 score predicted complications and postoperative events in the ASD population. The mFI-5 may effectively predict 30-day readmissions. Further research is needed to identify the benefits and predictive value of mFI-5 as a risk assessment tool.

Background: Although several studies have indirectly compared teaching and nonteaching hospitals, results are conflicting, and evaluation of the direct impact of trainee involvement is lacking. We investigated the direct impact of resident participation in primary total knee arthroplasties (TKAs). Material and methods: Fifty patients undergoing single-staged sequential bilateral primary TKAs were evaluated. The more symptomatic side was performed by the attending surgeon first, followed by the contralateral side performed by a chief resident under direct supervision and assistance of the same attending surgeon. Surgery was subdivided into 8 critical steps on both sides. The overall time and critical stepwise surgical time and short-term clinical outcomes were then compared between the 2 sides. Results: The attending surgeon completed the surgery (skin incision to dressing) significantly faster than the resident (70.2 vs 96.9 minutes) by a mean of 26.7 minutes (P < .05) and was also faster in all steps. The most significant differences in time were in "exposure" (9.5 vs 16.5 minutes) and "closure" steps (13.2 vs 24.9 minites), all P < .001. Adverse events occurred in 7 patients; 5 of these resolved uneventfully. There were no significant differences in surgical complications, objective outcome scores, or patient satisfaction scores between both sides. Conclusion: Resident participation in TKA increased operative time without jeopardizing short-term patient clinical outcomes, satisfaction, and complications. This may alleviate concerns from patients and policymakers about TKA in an academic setting. Surgical "exposure" and "closure" were the most prolonged steps for the residents, and they may benefit with more focus and/or simulation studies during training.
RESUMEN
Background: There is limited literature evaluating the impact of isolated cannabis use on outcomes for patients following spinal surgery. This study sought to compare 90-day complication, 90-day readmission, as well as 2-year revision rates between baseline cannabis users and non-users following thoracolumbar spinal fusion (TLF) for adult spinal deformity (ASD). Methods: The New York Statewide Planning and Research Cooperative System (SPARCS) database was queried between January 2009 and September 2013 to identify all patients who underwent TLF for ASD. Inclusion criteria were age ≥18 years and either minimum 90-day (for complications and readmissions) or 2-year (for revisions) follow-up surveillance. Cohorts were created and propensity score-matched based on presence or absence of isolated baseline cannabis use. Baseline demographics, hospital-related parameters, 90-day complications and readmissions, and two-year revisions were retrieved. Multivariate binary stepwise logistic regression identified independent outcome predictors. Results: 704 patients were identified (n=352 each), with comparable age, sex, race, primary insurance, Charlson/Deyo scores, surgical approach, and levels fused between cohorts (all, p>0.05). Cannabis users (versus non-users) incurred lower 90-day overall and medical complication rates (2.4% vs. 4.8%, p=0.013; 2.0% vs. 4.1%, p=0.018). Cohorts had otherwise comparable complication, revision, and readmission rates (p>0.05). Baseline cannabis use was associated with a lower risk of 90-day medical complications (OR=0.47, p=0.005). Isolated baseline cannabis use was not associated with 90-day surgical complications and readmissions, or two-year revisions. Conclusion: Isolated baseline cannabis use, in the absence of any other diagnosed substance abuse disorders, was not associated with increased odds of 90-day surgical complications or readmissions or two-year revisions, though its use was associated with reduced odds of 90-day medical complications when compared to non-users undergoing TLF for ASD. Further investigations are warranted to identify the physiologic mechanisms underlying these findings. Level of Evidence: III.

PURPOSE: Elbow flexion is one of the most important functions to restore following brachial plexus damage. The authors sought to systematically review available evidence to summarize outcomes of free gracilis and non-free muscle transfers in restoring elbow flexion. METHODS: MEDLINE, EMBASE, and Cochrane were searched to identify articles reporting on elbow flexion reanimation in terms of transfer failure rates, strengths, range of motion (ROM), and/or Disabilities of the Arm, Shoulder and Hand (DASH) scores. A systematic review was chosen to select studies and reported according to PRISMA guidelines. RESULTS: Forty-six studies met the inclusion criteria for this study. A total of 432 cases were gracilis free-flap muscle transfers (FFMT), and 982 cases were non-free muscle transfers. FFMT were shown to have higher Medical Research Council (MRC) strength scores than non-free muscle transfer groups. However, 42 studies, totaling 1,266 cases, were useful in evaluating graft failure, showing failure (MRC<3) in 77/419 (â¼18.4%) of gracilis free-flap transfers and 215/847 (â¼25.4%) of non-free muscle transfers. Sixteen articles, 285 cases, were useful to evaluate ROMs (total range: 0-140°), and eight articles, 215 cases, provided DASH scores (total range: 8-90.8). CONCLUSIONS: Of patients who underwent gracilis FFMT procedures, higher mean strength scores and lower failure rates were observed when compared with non-free muscle transfers. Articles reporting non-free muscle transfer procedures (pectoralis, pedicled, Steindler, vascularized ulnar nerve grafts, Oberlin, single/double nerve transfers) provided comprehensive insight into outcomes and indicated that they may result in pooerer poorer DASH scores and ROM.

INTRODUCTION: Osteoporosis affects nearly 200 million individuals worldwide. There are little available data regarding outcomes in patients with osteoporosis who undergo short-segment lumbar fusion for degenerative disk disease (DDD). We sought to identify a relationship between osteoporosis and risk of adverse outcomes in patients with DDD undergoing short-segment lumbar fusion. METHODS: Using the New York State Statewide Planning and Research Cooperative System, all patients with DDD who underwent 2- to 3-level lumbar fusion from 2009 through 2011 were identified. Patients with bone mineralization disorders and other systemic and endocrine disorders and surgical indications of trauma, systemic disease(s), and infection were excluded. Patients were stratified by the presence or absence of osteoporosis and compared for demographics, hospital-related parameters, and 2-year complications and revision surgeries. Multivariate binary logistic regression models were used to identify notable predictors of complications. RESULTS: A total of 29,028 patients (osteoporosis = 1,353 [4.7%], nonosteoporosis = 27,675 [95.3%]) were included. Patients with osteoporosis were older (66.9 vs 52.6 years), more often female (85.1% vs 48.4%), and White (82.8% vs 73.5%) (all P < 0.001). The Charlson/Deyo comorbidity index did not significantly differ between groups. Hospital lengths of stay and total charges were higher for patients with osteoporosis (4.9 vs 4.1 days; $74,484 vs $73,724; both P < 0.001). Medical complication rates were higher in patients with osteoporosis, including acute renal failure and deep-vein thrombosis (both P < 0.01). This cohort also had higher rates of implant-related (3.4% vs 1.9%) and wound (9.8% vs 5.9%) complications (both P < 0.01). Preoperative osteoporosis was strongly associated with 2-year medical and surgical complications (odds ratios, 1.6 and 1.7) as well as greater odds of revision surgeries (odds ratio, 1.3) (all P < 0.001). CONCLUSION: Patients with osteoporosis undergoing 2- to 3-level lumbar fusion for DDD were at higher risk of 2-year medical and surgical complications, especially implant-related and wound complications. These findings highlight the importance of rigorous preoperative metabolic workup and patients' optimization before spinal surgery.

INTRODUCTION: Approximately 300 000 hip fractures occur annually in the USA in patients >65 years old. Early intervention is key in reducing morbidity and mortality. Our institution implemented a collaborative hip fracture protocol, streamlining existing processes to reduce time to OR (TTO) and hospital length of stay (LOS). Our aim was to determine if this protocol improved these outcomes. STUDY DESIGN: We conducted a retrospective cohort study using our level-1 trauma center's trauma registry, comparing outcomes for patients >60 years old with isolated hip fractures pre-and post-hip protocol implementation in May 2018. Our primary outcomes were TTO and in-hospital mortality. Secondary outcomes included LOS and postoperative complications. Univariate analysis was done using chi-square and T-test. RESULTS: We identified 176 patients with isolated hip fractures: 69 post- and 107 pre-protocol. Comparing post- to pre-protocol, TTO decreased by 18hrs (39 vs 57h; P = .013) and patients had fewer postoperative complications (9 vs 23%; P = .016) despite post-protocol patients being more likely to have diabetes (42 vs 27%, P < .05), elevated BMI (22 vs 25; P < .001), and to be current smokers (9 vs 2%; P < .05). LOS and in-hospital mortality also decreased (11 vs 20d; P = .312, 4.3 vs 7.5%; P = .402). Post-protocol patients were more likely to go to the OR within 24hrs of presentation (39 vs 16%; P < .001) and to go straight from ED to OR (32 vs 4%; P < .001). CONCLUSION: TTO, LOS, and postoperative complications for isolated hip fracture patients were lower post-protocol. Though not all statistically significant, this trend indicates that the protocol was helpful in improving hip fracture outcomes but may require further improvement and institution-wide education.
