RESUMO
PURPOSE: Predict nonhome discharge (NHD) following elective anterior cervical discectomy and fusion (ACDF) using an explainable machine learning model. METHODS: 2227 patients undergoing elective ACDF from 2008 to 2019 were identified from a single institutional database. A machine learning model was trained on preoperative variables, including demographics, comorbidity indices, and levels fused. The validation technique was repeated stratified K-Fold cross validation with the area under the receiver operating curve (AUROC) statistic as the performance metric. Shapley Additive Explanation (SHAP) values were calculated to provide further explainability regarding the model's decision making. RESULTS: The preoperative model performed with an AUROC of 0.83 ± 0.05. SHAP scores revealed the most pertinent risk factors to be age, medicare insurance, and American Society of Anesthesiology (ASA) score. Interaction analysis demonstrated that female patients over 65 with greater fusion levels were more likely to undergo NHD. Likewise, ASA demonstrated positive interaction effects with female sex, levels fused and BMI. CONCLUSION: We validated an explainable machine learning model for the prediction of NHD using common preoperative variables. Adding transparency is a key step towards clinical application because it demonstrates that our model's "thinking" aligns with clinical reasoning. Interactive analysis demonstrated that those of age over 65, female sex, higher ASA score, and greater fusion levels were more predisposed to NHD. Age and ASA score were similar in their predictive ability. Machine learning may be used to predict NHD, and can assist surgeons with patient counseling or early discharge planning.

BACKGROUND AND AIMS: The incidence and prevalence of eosinophilic esophagitis (EoE) and inflammatory bowel disease (IBD) are rising with similar patterns. Co-occurrence of both diseases in the same patient has been increasingly reported. We sought to examine the pediatric population with both EoE and IBD to better understand the epidemiology and clinical implications of this overlap. METHODS: We conducted a retrospective case-control study at 2 tertiary care children's hospitals. Subjects with both EoE and IBD were identified and compared with randomly selected controls with EoE and IBD alone in terms of: demographics, atopic conditions, IBD classification, location and phenotype of Crohn disease (CD), IBD medications, endoscopic findings, and histopathology. Descriptive statistics summarized the data. RESULTS: Sixty-seven subjects with dual-diagnosis were identified across both institutions. The prevalence of IBD in the EoE population was 2.2% and EoE in IBD was 1.5%. Subjects with both diseases were more likely to have IgE-mediated food allergy compared with IBD alone (36% vs 7%, Pâ<â0.001). Subjects with CD-EoE were less likely to have perianal disease than CD alone (2% vs 20%, Pâ=â0.004). There was no difference in fibrostenotic EoE between the dual-diagnosis group and EoE alone. Treatment with a TNF-alpha inhibitor (anti-TNF) for management of preexisting IBD was protective against development of EoE with a relative risk of 0.314 [95% confidence interval [CI] 0.159-0.619]. CONCLUSIONS: This is a unique population in whom the underlying pathway leading to dual-diagnosis is unclear. Concomitant atopic conditions, especially IgE-mediated food allergy, and medication exposures, particularly anti-TNFs, may help predict likelihood of developing dual-diagnosis.

OBJECTIVES: No formal comparative effectiveness studies have been conducted to evaluate the effect of eosinophilic esophagitis (EoE) treatment choice on long-term growth in pediatric patients. Long-term studies of inhaled corticoid steroids in asthma, however, suggest possible effects on linear growth. The aim of this study was to compare longitudinal, anthropometric growth in children with EoE according to treatment approach. METHODS: We conducted a retrospective, multicenter cohort study of anthropometric growth (height and body mass index [BMI] z scores) in pediatric (<18 years of age) patients newly diagnosed with EoE across 5 clinical sites between 2005 and 2014. We compared differences in growth according to treatment approach over a 12-month period. Modification by sex and age was examined and sensitivity analyses were conducted to assess robustness of results given study assumptions. RESULTS: In the 409 patients identified, the mean age and proportion male differed by treatment (Pâ=ââ<â0.01 and Pâ=â0.04, respectively). Baseline growth measures were associated with slight impairment of height at diagnosis (median baseline height z score of -0.1 [interquartile range -0.9, 0.8]). In general, treatment approach was not associated with any significant increase or decrease in expected growth over a 12-month period. Subtle decrease in linear growth was observed with treatment using a combined elemental and topical steroid (Δ height z score [adjusted]: -0.04; 95% confidence interval [CI]: -0.08, -0.01). Differences in linear growth differed by sex (P for interaction <0.01). For elemental formula in combination with topical steroids, only girls exhibited a significant decline in linear growth (Δ height z score [adjusted]: -0.24; 95% CI: -0.32, -0.17). A slight reduction in BMI was observed for patients treated with a combination of elemental diet and dietary elimination (Δ BMI z score [adjusted]: -0.07; 95% CI: -0.13, -0.01). CONCLUSIONS: Treatment of EoE, in general, is not associated with major anthropometric growth changes in most pediatric patients. Slight linear growth impairment was observed for topical steroid treatment, and sex differences in growth by treatment approach were observed. Future prospective studies should evaluate the effect of treatment on optimal growth and development and over a longer period of follow-up.

BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic disease characterized by infiltration of eosinophils in the esophageal epithelium. There are limited treatment options for EoE. The rationale of the study was to evaluate the long-term safety and efficacy of reslizumab (RSZ) in pediatric patients who received RSZ in a randomized controlled trial (RCT) and expanded access program. METHODS: Records of patients who received RSZ in our center were reviewed. Patients received RSZ 2âmg/kg (or placebo) every 4 weeks as part of the RCT, open-label extension (OLE), and compassionate use (CU). Data were analyzed as of their most recent evaluation in August 2017. Labwork, history, and examinations were conducted every 12 weeks. Biopsy results were compared from baseline (before RCT) and at the most recent evaluation. Adverse events (AE) were recorded. RESULTS: Twelve patients entered the RCT at our center; 6 patients completed the OLE and 4 received RSZ through CU. Between the RCT, OLE, and CU periods, patients received 549 doses of RSZ (median 37, range 2-116). No serious AE were attributed to RSZ. Symptoms improved on treatment: dysphagia (42% vs 0%), abdominal pain (58% vs 0%), heartburn (18% vs 0%), vomiting (67% vs. 17%), reflux (58% vs. 0%). Median esophageal eosinophil count improved (35âeosinophils per high-power field vs 3, Pâ<â0.001). Patients receiving RSZ maintain a relatively unrestricted diet. CONCLUSIONS: RSZ appears to be safe in children with EoE over 9 years of treatment experience. Symptoms and eosinophil count improved considerably during treatment with RSZ despite a relatively unrestricted diet.

BACKGROUND: Mobile applications and interactive websites are an increasingly used method of telemedicine, but their use lacks evidence in digestive diseases. AIM: This study aims to explore digestive disease studies that use telemedicine to effectively manage disease activity, help monitor symptoms, improve compliance to the treatment protocol, increase patient satisfaction, and enhance the patient-to-provider communication. METHODS: EBSCO, PubMed, and Web of Science databases were searched using Medical Subject Headings and other keywords to identify studies that utilized telemedicine in patients with digestive disease. The PRISMA guidelines were used to identify 20 research articles that had data aligning with 4 common overlapping themes including, patient compliance (n = 13), patient satisfaction (n = 11), disease activity (n = 15), and quality of life (n = 13). The studies focused on digestive diseases including inflammatory bowel disease (n = 7), ulcerative colitis (n = 4), Crohn's Disease (n = 1), irritable bowel syndrome (n = 6), and colorectal cancer (n = 2). RESULTS: From the studies included in this systematic review, patient compliance and patient satisfaction ranged between 25.7-100% and 74-100%, respectively. Disease activity, measured by symptom severity scales and physiological biomarkers, showed improvements following telemedicine interventions in several, but not all, studies. Similar to disease activity, general and disease-specific quality of life showed improvements following telemedicine interventions in as little as 12 weeks in some studies. CONCLUSION: Telemedicine and mobile health technology may be effective in managing disease activity and improving quality of life in digestive diseases. Future studies should explore both gastrointestinal and gastroesophageal diseases using these types of interventions.

OBJECTIVES: Differences in the initial management of pediatric eosinophilic esophagitis (EoE) by practice setting have not been well characterized. We aimed to characterize these differences for sites in the Carolinas EoE Collaborative (CEoEC), a multicenter network of academic and community practices. METHODS: We performed a retrospective cohort study of pediatric EoE patients at five CEoEC sites: University of North Carolina (UNC) Hospital, Charlotte Asthma and Allergy Specialists, Greenville Health Systems, Wake Forest Baptist Medical Center, and the Medical University of South Carolina Hospital. Cases of EoE were defined by consensus guidelines. Data were extracted from electronic medical records. We tested for differences among sites and used a multinomial model (polytomous regression) to assess associations between treatment and site, adjusting on patient factors. RESULTS: We identified 464 children with EoE across the CEoEC sites. The median age was highest at Wake Forest (11.4 years), the median eosinophil count was highest at UNC (69 eos/hpf), and UNC had the most male patients (82%). UNC used topical steroids for initial treatment in 86% of cases, compared with <1% in Greenville (P < 0.01). Greenville used dietary elimination more frequently than UNC (81% vs 2%, P < 0.01). Differences in treatment approach held after adjusting for potential baseline confounders. There was no significant association between patient factors and initial treatment approach. CONCLUSIONS: Significant differences in EoE patient factors and treatment approaches were identified across CEoEC sites and were not explained by patient or practice factors. This suggests that institutional or provider preferences drive initial treatment approaches, and that more data are needed to drive best practice decisions.

OBJECTIVE: To understand parent and child perception of spaces experienced during outpatient procedures and to measure their anxiety in these spaces. BACKGROUND: Same-day procedures are becoming prevalent among children in the United States. While studies conducted in different types of healthcare settings show that the physical environment influences healthcare experiences of patients, there is a lack of research on patient and family perceptions of the physical environment of the outpatient centers where such procedures are conducted. METHODS: This study used ecological momentary assessment to collect patient experience and anxiety data at different points during the patient's journey through an ambulatory surgical center where pediatric gastrointestinal (GI) procedures were performed. Objective and subjective measures of anxiety were collected. A Qualtrics survey asked participants' perceptions about four spaces-waiting, preprocedure, procedure, and recovery. RESULTS: Child participants reported liking murals, double chairs, patient beds, wall color, and access to a television. They disliked medical equipment and lack of child-friendly furniture. Most parents liked the murals, access to a television, and nature photos, while disliking the lack of privacy, lack of toys in waiting areas, and lack of child-friendly furniture. On average, both children and parents experienced the highest anxiety levels before and during the procedure and the lowest during recovery. Between the four spaces, no significant differences were observed in the heart rate variability and skin conductance responses for both groups. CONCLUSIONS: Despite the outpatient nature of the procedures, participants experienced anxiety before the GI procedure. Comfortable design features that provide distractions are preferred by children and their parents.

AIM: The study aims to evaluate the impact of exposure to a highly realistic virtual facility tour prior to the on-site visit on patients and their parent/care partner's self-reported anxiety and physiological measures on the day of the procedure. BACKGROUND: Preoperative anxiety impacts pediatric surgical outcomes; therefore, it is important for healthcare providers to address and manage preoperative anxiety in pediatric patients to promote better outcomes and overall wellbeing. Providing patients with a preview of the care setting before the actual procedure can be highly beneficial in mitigating preoperative anxiety. METHODOLOGY: In this pilot randomized experimental study, sixteen patient-care partner dyads scheduled to undergo a gastrointestinal procedure either received a virtual tour identical to the places experienced on the day of the procedure (experimental group) or received no virtual tour (control group). Self-reported measures of anxiety were collected from participants before and on the day of the procedure. Physiological measures of heart rate variability and skin conductance were collected on the day of the procedure from both groups. RESULTS: There were no significant differences between the self-reported and physiological measures of anxiety between the child groups. However, parents in the control group reported lower levels of anxiety and demonstrated lower levels of stress based on their physiological measures. CONCLUSION: Exposure to virtual facility tours days before the surgery was not helpful in positively impacting the psychological measures related to preoperative anxiety levels for the participants.

STUDY DESIGN: Comparative analysis. OBJECTIVE: To evaluate Chat Generative Pre-trained Transformer (ChatGPT's) ability to predict appropriate clinical recommendations based on the most recent clinical guidelines for the diagnosis and treatment of low back pain. BACKGROUND: Low back pain is a very common and often debilitating condition that affects many people globally. ChatGPT is an artificial intelligence model that may be able to generate recommendations for low back pain. MATERIALS AND METHODS: Using the North American Spine Society Evidence-Based Clinical Guidelines as the gold standard, 82 clinical questions relating to low back pain were entered into ChatGPT (GPT-3.5) independently. For each question, we recorded ChatGPT's answer, then used a point-answer system-the point being the guideline recommendation and the answer being ChatGPT's response-and asked ChatGPT if the point was mentioned in the answer to assess for accuracy. This response accuracy was repeated with one caveat-a prior prompt is given in ChatGPT to answer as an experienced orthopedic surgeon-for each question by guideline category. A two-sample proportion z test was used to assess any differences between the preprompt and postprompt scenarios with alpha=0.05. RESULTS: ChatGPT's response was accurate 65% (72% postprompt, P =0.41) for guidelines with clinical recommendations, 46% (58% postprompt, P =0.11) for guidelines with insufficient or conflicting data, and 49% (16% postprompt, P =0.003*) for guidelines with no adequate study to address the clinical question. For guidelines with insufficient or conflicting data, 44% (25% postprompt, P =0.01*) of ChatGPT responses wrongly suggested that sufficient evidence existed. CONCLUSION: ChatGPT was able to produce a sufficient clinical guideline recommendation for low back pain, with overall improvements if initially prompted. However, it tended to wrongly suggest evidence and often failed to mention, especially postprompt, when there is not enough evidence to adequately give an accurate recommendation.

BACKGROUND: Eosinophilic esophagitis is a chronic allergic disease with insufficient treatment options. Results from animal studies suggest that IL-5 induces eosinophil trafficking in the esophagus. OBJECTIVE: We sought to evaluate the effect of reslizumab, a neutralizing antibody against IL-5, in children and adolescents with eosinophilic esophagitis. METHODS: Patients with symptom severity scores of moderate or worse and an esophageal biopsy specimen with 24 or more intraepithelial eosinophils per high-power field were randomly assigned to receive infusions of 1, 2, or 3 mg/kg reslizumab or placebo at weeks 0, 4, 8, and 12. The coprimary efficacy measures were changes in peak esophageal eosinophil count and the physician's global assessment score at week 15 (end of therapy). RESULTS: Two-hundred twenty-six patients received study medication. Median reductions from baseline to the end of therapy in peak esophageal eosinophil counts were 59%, 67%, 64%, and 24% in the 1, 2, and 3 mg/kg reslizumab (all P < .001) and placebo groups, respectively. All treatment groups, including the placebo group, showed improvements in physician's global assessment scores; the differences between the reslizumab and placebo groups were not statistically significant. The most common adverse events in the reslizumab groups were headache, cough, nasal congestion, and upper respiratory tract infection. One patient in each reslizumab group and 2 in the placebo group had serious adverse events; none were considered related to the study medication. CONCLUSION: Reslizumab significantly reduced intraepithelial esophageal eosinophil counts in children and adolescents with eosinophilic esophagitis. However, improvements in symptoms were observed in all treatment groups and were not associated with changes in esophageal eosinophil counts.

BACKGROUND: Anterior vertebral body tethering (AVBT) has been approved for skeletally immature (IM) adolescent idiopathic scoliosis patients, but the role of AVBT in patients with minimal remaining skeletal growth is controversial. The purpose of this study was to compare minimum 2-year (YR2) outcomes in skeletally IM patients vs those with minimal remaining skeletal growth. METHODS: Patients with single thoracic AVBT were grouped by their preoperative (PR) skeletal maturity: IM (n = 16, Risser 0-2) vs mature (M, n = 19, Risser 3-5). Outcomes were assessed at PR, first erect (FE), and YR2. Median (range) was compared with nonparametric tests (P < 0.05). RESULTS: The PR age was 12.5 (9-16) vs 15 (12-18) years with major Cobb 51° (36°-69°) and 49° (40°-69°) for IM and M, respectively. At FE, there was no difference in correction; however, at YR2, the IM group yielded a lower residual curve (15° [-16° to 38°] vs 29° [12°-42°], P = 0.008). Thoracolumbar/lumbar curves were corrected without group differences. Clinically successful correction (<35°) (15 [94%] vs 15 [79%]) and suspected cord breakages (2 [13%] vs 2 [12%]) were similar at YR2. Two overcorrections occurred, both in IM patients. Scoliosis Research Society-22 outcomes at final follow-up were similar between groups. No revision reoperations or conversions to spinal fusion were needed. CONCLUSIONS: Skeletally IM patients benefit from greater growth-modulated curve correction than M patients, however, at the increased risk of overcorrection. M patients maintained clinically significant correction at latest follow-up. Longer-term follow-up is required to determine durability of outcomes for patients undergoing AVBT who have minimal remaining growth at the time of index surgery. CLINICAL RELEVANCE: This study is relevant to spine surgeons, spine physiotherapists, and patients with idiopathic scoliosis. It offers evidence of clinical correction of scoliosis in mature patients.
RESUMO
OBJECTIVE: The "weekend effect" occurs when patients cared for during weekends versus weekdays experience worse outcomes. But reasons for this effect are unclear, especially amongst patients undergoing elective cervical spinal fusion (ECSF). Our aim was to analyze whether index weekend admission affects 30- and 90-day readmission rates post-ECSF. METHODS: All ECSF patients > 18 years were retrospectively identified from the 2016-2018 Healthcare Cost and Utilization Project Nationwide Readmissions Database (NRD), using unique patient linkage codes and International Classification of Diseases, Tenth Revision codes. Patient demographics, comorbidities, and outcomes were analyzed. Univariate logistic regression analyzed primary outcomes of 30- and 90-day readmission rates in weekday or weekend groups. Multivariate regression determined the impact of complications on readmission rates. RESULTS: Compared to the weekday group (n = 125,590), the weekend group (n = 1,026) held a higher percentage of Medicare/Medicaid insurance, incurred higher costs, had longer length of stay, and fewer routine home discharge (all p < 0.001). There was no difference in comorbidity burden between weekend versus weekday admissions, as measured by the Elixhauser Comorbidity Index (p = 0.527). Weekend admissions had higher 30-day (4.30% vs. 7.60%, p < 0.001) and 90-day (7.80% vs. 16.10%, p < 0.001) readmission rates, even after adjusting for sex, age, insurance status, and comorbidities. All-cause complication rates were higher for weekend admissions (8.62% vs. 12.7%, p < 0.001), specifically deep vein thrombosis, infection, neurological conditions, and pulmonary embolism. CONCLUSION: Index weekend admission increases 30- and 90-day readmission rates after ECSF. In patients undergoing ECSF on weekends, postoperative care for patients at risk for specific complications will allow for improved outcomes and health care utilization.
RESUMO
Objective: Investigate the patient opinion on the use of Artificial Intelligence (AI) in Orthopaedics. Methods: 397 orthopaedic patients from a large urban academic center and a rural health system completed a 37-component survey querying patient demographics and perspectives on clinical scenarios involving AI. An average comfort score was calculated from thirteen Likert-scale questions (1, not comfortable; 10, very comfortable). Secondary outcomes requested a binary opinion on whether it is acceptable for patient healthcare data to be used to create AI (yes/no) and the impact of AI on: orthopaedic care (positive/negative); healthcare cost (increase/decrease); and their decision to refuse healthcare if cost increased (yes/no). Bivariate and multivariable analyses were employed to identify characteristics that impacted patient perspectives. Results: The average comfort score across the population was 6.4, with significant bivariate differences between age (p = 0.0086), gender (p = 0.0001), education (p = 0.0029), experience with AI/ML (p < 0.0001), survey format (p < 0.0001), and four binary outcomes (p < 0.05). When controlling for age and education, multivariable regression identified significant relationships between comfort score and experience with AI/ML (p = 0.0018) and each of the four binary outcomes (p < 0.05). In the final multivariable model gender, survey format, perceived impact of AI on orthopaedic care, and the decision to refuse care if it were to increase cost remained significantly associated with the average AI comfort score (p < 0.05). Additionally, patients were not comfortable undergoing surgery entirely by a robot with distant physician supervision compared to close supervision. Conclusion: The orthopaedic patient appears comfortable with AI joining the care team.
RESUMO
STUDY DESIGN: A retrospective database study of patients at an urban academic medical center undergoing an Anterior Cervical Discectomy and Fusion (ACDF) surgery between 2008 and 2019. OBJECTIVE: ACDF is one of the most common spinal procedures. Old age has been found to be a common risk factor for postoperative complications across a plethora of spine procedures. Little is known about how this risk changes among elderly cohorts such as the difference between elderly (60+) and octogenarian (80+) patients. This study seeks to analyze the disparate rates of complications following elective ACDF between patients aged 60-69 or 70-79 and 80+ at an urban academic medical center. METHODS: We identified patients who had undergone ACDF procedures using CPT codes 22,551, 22,552, and 22,554. Emergent procedures were excluded, and patients were subdivided on the basis of age. Then each cohort was propensity matched for univariate and univariate logistic regression analysis. RESULTS: The propensity matching resulted in 25 pairs in both the 70-79 and 80+ y.o. cohort comparison and 60-69 and 80+ y.o. cohort comparison. None of the cohorts differed significantly in demographic variables. Differences between elderly cohorts were less pronounced: the 80+ y.o. cohort experienced only significantly higher total direct cost (P = .03) compared to the 70-79 y.o. cohort and significantly longer operative time (P = .04) compared to the 60-69 y.o. cohort. CONCLUSIONS: Octogenarian patients do not face much riskier outcomes following elective ACDF procedures than do younger elderly patients. Age alone should not be used to screen patients for ACDF.
RESUMO
Eosinophilic esophagitis (EoE) is a clinicopathologic condition of increasing recognition and prevalence. In 2007, a consensus recommendation provided clinical and histopathologic guidance for the diagnosis and treatment of EoE; however, only a minority of physicians use the 2007 guidelines, which require fulfillment of both histologic and clinical features. Since 2007, the number of EoE publications has doubled, providing new disease insight. Accordingly, a panel of 33 physicians with expertise in pediatric and adult allergy/immunology, gastroenterology, and pathology conducted a systematic review of the EoE literature (since September 2006) using electronic databases. Based on the literature review and expertise of the panel, information and recommendations were provided in each of the following areas of EoE: diagnostics, genetics, allergy testing, therapeutics, and disease complications. Because accumulating animal and human data have provided evidence that EoE appears to be an antigen-driven immunologic process that involves multiple pathogenic pathways, a new conceptual definition is proposed highlighting that EoE represents a chronic, immune/antigen-mediated disease characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominant inflammation. The diagnostic guidelines continue to define EoE as an isolated chronic disorder of the esophagus diagnosed by the need of both clinical and pathologic features. Patients commonly have high rates of concurrent allergic diatheses, especially food sensitization, compared with the general population. Proved therapeutic options include chronic dietary elimination, topical corticosteroids, and esophageal dilation. Important additions since 2007 include genetic underpinnings that implicate EoE susceptibility caused by polymorphisms in the thymic stromal lymphopoietin protein gene and the description of a new potential disease phenotype, proton pump inhibitor-responsive esophageal eosinophila. Further advances and controversies regarding diagnostic methods, surrogate disease markers, allergy testing, and treatment approaches are discussed.

BACKGROUND: Hallux valgus is a common cause of pain and dysfunction of the foot, sometimes requiring surgical correction when conservative measures fail. Although there are many methods of correction, one of the newer techniques is minimally invasive chevron-Akin (MICA). The aim of the current study is to evaluate clinical and radiographic effectiveness of MICA and narcotic use in a large patient cohort. METHODS: All patients in this retrospective study were treated by a single fellowship-trained foot and ankle orthopaedic surgeon. Patient demographics were collected for all cases. Preoperative and postoperative intermetatarsal angle (IMA) and hallux valgus angle (HVA) were measured in all patients on weightbearing 3-views radiographs. The Foot Function Index (FFI) was obtained pre- and postoperatively at each visit. All patients were prescribed regular use of ibuprofen for 3 days with acetaminophen and oxycodone reserved for breakthrough pain. Use of narcotic pain medication was recorded. RESULTS: A total of 274 feet in 248 patients were included in the study. Overall, 87.9% were female and 12.1% were male. The mean preoperative IMA and HVA were 13.4 and 29.1 degrees, respectively. The postoperative IMA and HVA were 4.9 and 8.9 degrees, respectively. The mean FFI score part A was 92 preoperatively and 43 postoperatively. Patient satisfaction was 91.6%. The mean postoperative 5 mg oxycodone pill consumption was 2.2. CONCLUSION: MICA is good method to correct hallux valgus deformity with low postoperative narcotic use. LEVEL OF EVIDENCE: Level III, restrospective cohort study of a single surgeon practice.

OBJECTIVE: Subsidence following anterior cervical discectomy and fusion (ACDF) may lead to disruptions of cervical alignment and lordosis. The purpose of this study was to evaluate the effect of subsidence on segmental, regional, and global lordosis. METHODS: This was a retrospective cohort study performed between 2016-2021 at a single institution. All measurements were performed using lateral cervical radiographs at the immediate postoperative period and at final follow-up greater than 6 months after surgery. Associations between subsidence and segmental lordosis, total fused lordosis, C2-7 lordosis, and cervical sagittal vertical alignment change were determined using Pearson correlation and multivariate logistic regression analyses. RESULTS: One hundred thirty-one patients and 244 levels were included in the study. There were 41 one-level fusions, 67 two-level fusions, and 23 three-level fusions. The median follow-up time was 366 days (interquartile range, 239-566 days). Segmental subsidence was significantly negatively associated with segmental lordosis change in the Pearson (r = -0.154, p = 0.016) and multivariate analyses (beta = -3.78; 95% confidence interval, -7.15 to -0.42; p = 0.028) but no associations between segmental or total fused subsidence and any other measures of cervical alignment were observed. CONCLUSION: We found that subsidence is associated with segmental lordosis loss 6 months following ACDF. Surgeons should minimize subsidence to prevent long-term clinical symptoms associated with poor cervical alignment.
