What is the Trend in Representation of Women and Under-represented Minorities in Orthopaedic Surgery Residency?

BACKGROUND: Orthopaedic surgery training programs have lagged behind other surgical specialties in increasing their representation of women and people from under-represented minority (URM) groups. Comparative data between orthopaedic surgery and other specialties are needed to help identify solutions to closing the diversity gap. QUESTIONS/PURPOSES: (1) Which surgical specialties have the greatest representation of women residents and residents from URM groups? (2) How have the proportions of women residents and residents from URM groups changed across the surgical specialties during the past decade? METHODS: This was a retrospective evaluation of a large, longitudinally maintained survey database. Resident data by gender and ethnicity were retrieved from the Accreditation Council for Graduate Medical Education Data Resource Books for the 2011 to 2012 through 2019 to 2020 academic years. The Accreditation Council for Graduate Medical Education database is updated annually; thus, it is the most up-to-date and complete database available for gender and ethnicity data for all surgical residents. Data were obtained and analyzed for seven different surgical specialties: orthopaedic surgery, neurosurgery, ophthalmology, otolaryngology, plastic surgery, general surgery, and urology. No sampling was necessary, and thus descriptive statistics of the data were completed. Because the entire population of residents was included for the period of time in question, no statistical comparisons were made, and the reported differences represent absolute differences between the groups for these periods. Linear regression analyses were performed to estimate the annual growth rates of women residents and residents from URM groups in each specialty. RESULTS: Among the seven surgical specialties, representation of women residents increased from 28% (4640 of 16,854) of residents in 2012 to 33% (6879 of 20,788) in 2020. Orthopaedic surgery had the lowest representation of women residents every year, with women residents comprising 16% of residents (700 of 4342) in 2020. Among the seven surgical specialties, representation of residents from URM groups increased from 8.1% (1362 of 16,854) in 2012 to 9.7% (2013 of 20,788) in 2020. In 2020, the representation of residents from URM groups in orthopaedic surgery was 7.7% (333 of 4342). In 2020, general surgery had the highest representation of women residents (42%; 3696 of 8809) as well as residents from URM groups (12%; 1065 of 8809). Plastic surgery (1.46% per year) and general surgery (0.95% per year) had larger annual growth rates of women residents than the other specialties did. In each surgical specialty, the annual growth rate of residents from URM groups was insignificant. CONCLUSION: During the past decade, there was only a small increase in the representation of women in orthopaedic surgery, while the representation of people from URM groups did not change. In contrast, by 2020, general surgery had become the most diverse among the seven surgical specialties. To increase diversity in our field, we need to evaluate and implement some of the effective interventions that have helped general surgery become the diverse surgical specialty that it is today. CLINICAL RELEVANCE: General surgery has substantially reduced gender and ethnic disparities that existed in the past, while those in orthopaedic surgery still persist. General surgery residencies have implemented a holistic review of resident applications and longitudinal mentoring programs to successfully address these disparities. Orthopaedic surgery programs should consider placing less emphasis on United States Medical Licensing Examination score thresholds and more weight on applicants' non-academic attributes, and put more efforts into targeted longitudinal mentorship programs, some of which should be led by non-minority faculty.

A retrospective review comparing two-year patient-reported outcomes, costs, and healthcare resource utilization for TLIF vs. PLF for single-level degenerative spondylolisthesis.

PURPOSE: The purpose of this study was to compare patient-reported outcomes (PROs), morbidity, and costs of TLIF vs PLF to determine whether one treatment was superior in the setting of single-level degenerative spondylolisthesis. METHODS: Patients undergoing TLIF or PLF for single-level spondylolisthesis were included for retrospective analysis. EQ-5D, ODI, SF-12 MCS/PCS, NRS-BP/LP scores were collected at baseline and 24 months after surgery. 90-day post-operative complications, revision surgery rates, and satisfaction scores were also collected. Two-year resource use was multiplied by unit costs based on Medicare payment amounts (direct cost). Patient and caregiver workday losses were multiplied by the self-reported gross-of-tax wage rate (indirect cost). Total cost was used to assess mean total 2-year cost per QALYs gained after surgery. RESULTS: 62 and 37 patients underwent TLIF and PLF, respectively. Patients in the PLF group were older (p < 0.01). No significant differences were seen in baseline or 24-month PROs between the two groups. There was a significant improvement in all PROs from baseline to 24 months after surgery (p < 0.001). Both groups had similar rates of 90-day complications, revision surgery, satisfaction, and similar gain in QALYs and cost per QALYs gained. There was no significant difference in 24-month direct, indirect, and total cost. CONCLUSIONS: Overall costs and health care utilization were similar in both the groups. Both TLIF and PLF for single-level degenerative spondylolisthesis provide improvement in disability, pain, quality of life, and general health.

Impact of old age on patient-report outcomes and cost utility for anterior cervical discectomy and fusion surgery for degenerative spine disease.

PURPOSE: With growing older population and increasing rates of cervical spinal surgery, it is vital to understand the value of cervical surgery in this population. We set forth to determine the cost utility following anterior cervical decompression and fusion (ACDF) for degenerative disease in older patients. METHODS: Patients undergoing ACDF for degenerative diseases were enrolled into prospective longitudinal registry. Patient-reported outcomes (PROs) were recorded at baseline, 1-year, and 2-year postoperatively. Two-year medical resource utilization, missed work, and health-state values [quality-adjusted life years (QALYs)] were assessed to compute cost per QALY gained. Patients were dichotomized based on age: <65 years (younger) and ≥65 years (older) to compare the cost utility in these age groups. RESULTS: Total 218 (87%) younger patients and 33 (13%) older patients who underwent ACDF were analyzed. Both the groups demonstrated a significant improvement in PROs 2-year following surgery. The older patients had a lower mean cumulative gain in QALYs compared to younger patients at 1 year (0.141 vs. 0.28, P = 0.05) and 2 years (0.211 vs. 0.424, P = 0.04). There was no significant difference in the mean total 2-year cost between older [$21,041 (95% CI $18,466-$23,616)] and younger [$22,669 (95% CI $$21,259-$24,079)] patients (P = 0.27). Two-year cost per QALY gained in older vs. younger patients was ($99,720/QALYs gained vs. ($53,464/QALYs gained, P = 0.68). CONCLUSION: ACDF surgery provided a significant gain in health-state utility in older patients with degenerative cervical pathology, with a mean cumulative 2-year cost per QALY gained of $99,720/QALY. While older patients have a slightly higher cost utility compared to their younger counterparts, surgery in the older cohort does provide a significant improvement in pain, disability, and quality-of-life outcomes.

Preoperative and surgical factors associated with postoperative intensive care unit admission following operative treatment for degenerative lumbar spine disease.

PURPOSE: Evaluate the factors associated with postoperative ICU admission in patients undergoing surgical management of degenerative lumbar spine disease. METHODS: Patients undergoing surgery for degenerative lumbar spine disease were enrolled into a prospective registry over a 2-year period. Preoperative variables (age, gender, ASA grade, ODI%, CAD, HTN, MI, CHF, DM, BMI, depression, anxiety) and surgical variables (instrumentation, arthrodesis, estimated blood loss, length of surgery) were collected prospectively. Postoperative ICU admission details were retrospectively determined from the electronic medical record. Student's t test (continuous variables) and Chi-square test (categorical variables) were used to determine the association of each preoperative and surgical variable with ICU admission. RESULTS: 808 Patients (273 laminectomy, 535 laminectomy and fusion) were evaluated. Forty-one (5.1%) patients were found to have postoperative ICU admissions. Reasons for admission included blood loss (12.2%), cardiac (29.3%), respiratory (19.5%), neurologic (31.7%), and other (7.3%). For preoperative variables, female gender (P < 0.001), history of CAD (P = 0.003), history of MI (P = 0.008), history of CHF (P = 0.001), age (P = 0.025), and ASA grade (P = 0.008) were significantly associated with ICU admission. For surgical variables, estimated blood loss (P < 0.001) and length of surgery (P < 0.001) were significantly associated with ICU admission. CONCLUSIONS: Age, female gender, ASA grade, cardiac comorbidities, intraoperative blood loss, and length of surgery were associated with increased risk of postoperative ICU admission. Knowledge of these factors can aid surgeons in patient selection and preoperative discussion with patients about potential need for unexpected admission to the ICU.

Is obesity associated with worse patient-reported outcomes following lumbar surgery for degenerative conditions?

PURPOSE: To investigate whether obesity is associated with worse patient-reported outcomes following surgery for degenerative lumbar conditions. METHODS: We evaluated consecutive patients undergoing elective lumbar laminectomy or laminectomy with fusion for degenerative lumbar conditions. The Oswestry Disability Index (ODI), EuroQol-5D (EQ-5D), Short-Form 12 (SF-12), and NASS patient satisfaction were utilized. Chi-square tests and student t test assessed the association of obesity with PROs. Multivariate regression controlled for age, sex, smoking status, anxiety, depression, revision, preoperative narcotic use, payer status, and diabetes. RESULTS: A total of 602 patients were included. All PROs improved significantly in both groups. BMI ≥35 was associated with increased ODI at baseline (50.6 vs. 47.2 %, p = 0.012) and 12 months (30.5 vs. 25.7 %, p = 0.005). There was no difference in ODI change scores (21.2 vs. 19.4 %, p = 0.32). With multivariate analysis, BMI ≥35 was not predictive of worse ODI at 12 months (correlation coefficient 1.23, 95 % CI -0.225 to 2.676.) There was no significant difference between groups in percentage of patients achieving the minimum clinically important difference for ODI (59.6 vs. 64 %, p = 0.46) or patient satisfaction (80.5 vs. 78.9 %, p = 0.63). CONCLUSIONS: Body mass index ≥35 is associated with worse baseline and 12-month PROs, however, there was no difference in change scores across BMI groups. Controlling for important co-variables, BMI greater than 35 was not an independent predictor of worse PROs at 12 months.

Trends in the Main Residency Match From 2007 to 2020.

Background The United States Medical Licensing Exam (USMLE) Step 1 was recently changed from a numerically scored grading system to a pass/fail grading system. Until late 2024, there will be no formal studies about the impact that the grading change will have on the match process. To thoroughly assess the impact that this change will have on the overall match process, it is important to look at what the trends in applicants' objective measures have been in the years before the change. We aim to systematically evaluate the rates of change and mean trend of objective metrics found in residency applications in the main residency match.  Methods Objective medical student data of matched and unmatched applicants were queried from the National Matching Program's Charting Outcomes in the Match Reports for the 2007 to 2020 application cycles. Data were used to create linear regression analyses and statistical tests were performed to evaluate trends over time. Results For matched applicants, there were statistically significant positive trends for the mean number of contiguous ranks (m=0.33, p<0.01), having another non-doctoral graduate degree (m=0.67, p<0.01), membership to Alpha Omega Alpha (AOA) honor society (m=0.22, p<0.01), mean USMLE Step 1 score (m=1.01, p<0.01), mean USMLE Step 2 score (m=1.68, p<0.01), mean number of research experiences (m=0.12, p<0.01), and mean number of abstracts, presentations, and publications (m=0.34, p<0.01). Additionally, there was a statistically significant negative trend for the percentage who graduated from a top 40 National Institutes of Health-funded medical school (m=-0.41, p<0.01). For unmatched applicants, there were statistically significant positive trends for having another non-doctoral graduate degree (m=0.83, p<0.01), mean USMLE Step 1 score (m=1.26, p<0.01), mean USMLE Step 2 score (m=2.27, p<0.01), mean number of research experiences (m=0.13, p<0.01), and mean number of abstracts, presentations, and publications (m=0.33, p<0.01). Conclusion Our study shows that there have been statistically significant increases in almost all objective measures in the residency application. Recent changes to the abstracts, presentations, and publications on the Step 1 scoring system will force almost all residency programs to overhaul their application process and potentially increase reliance on Step 2, research, and other nonobjective factors. For students early in their medical education, emphasis on Step 2 and research will yield increased chances of matching into residency in the future.

Factors Associated With Total Discharge Opioid Prescription Morphine Milligram Equivalent Amounts Following Primary Anterior Cervical Spine Surgery.

BACKGROUND: Opioid overuse is a substantial cause of morbidity and mortality in the United States, and orthopaedic surgeons are the third highest prescribers of opioids. Postoperative prescribing patterns vary widely, and there is a paucity of data evaluating patient and surgical factors associated with discharge opioid prescribing patterns after elective anterior cervical surgery (ACS). The purpose of this study was to evaluate the volume of postoperative opioids prescribed and factors associated with discharge opioid prescription volumes after elective ACS. METHODS: We retrospectively identified patients aged 18 years and older who underwent elective primary anterior cervical diskectomy and fusion (ACDF), cervical disk arthroplasty (CDA), or hybrid procedure (ACDF and CDA at separate levels) at a single institution between 2015 and 2021. Demographic, surgical, and opioid prescription data were obtained from patients' electronic medical records. Univariate and multivariate analyses were conducted to assess for independent associations with discharge opioid volumes. RESULTS: A total of 313 patients met inclusion criteria, including 226 (72.2%) ACDF, 69 (22.0%) CDA, and 18 (5.8%) hybrid procedure patients. Indications included radiculopathy in 63.6%, myelopathy in 19.2%, and myeloradiculopathy in 16.3%. The average age was 57.2 years, and 50.2% of patients were male. Of these, 88 (28.1%) underwent one-level, 137 (43.8%) underwent two-level, 83 (26.5%) underwent three-level, and 5 (1.6%) underwent four-level surgery. Younger age (P = 0.010), preoperative radiculopathy (P = 0.029), procedure type (ACDF, P < 0.001), preoperative opioid use (P = 0.012), and discharge prescription written by a midlevel provider (P = 0.010) were independently associated with greater discharge opioid prescription volumes. CONCLUSION: We identified wide variability in prescription opioid discharge volumes after ACS and patient, procedure, and perioperative factors associated with greater discharge opioid volumes. These factors should be considered when designing protocols and interventions to reduce and optimize postoperative opioid use after ACS.

Sociodemographic Characteristics of Patients Undergoing Surgery for Metastatic Disease of the Spine.

INTRODUCTION: Some patients, particularly those who are socioeconomically deprived, are diagnosed with primary and/or metastatic cancer only after presenting to the emergency department. Our objective was to determine sociodemographic characteristics of patients undergoing surgery for metastatic spine disease at our institution. METHODS: This retrospective case series included patients 18 years and older who presented to the emergency department with metastatic spine disease requiring surgery. Demographics and survival data were collected. Sociodemographic characteristics were estimated using the Social Deprivation Index (SDI) and Area Deprivation Index (ADI) for the state of California. Univariate log-rank tests and Kaplan-Meier curves were used to assess differences in survival for predictors of interest. RESULTS: Between 2015 and 2021, 64 patients underwent surgery for metastatic disease of the spine. The mean age was 61.0 ± 12.5 years, with 60.9% being male (n = 39). In this cohort, 89.1% of patients were non-Hispanic (n = 57), 71.9% were White (n = 46), and 62.5% were insured by Medicare/Medicaid (n = 40). The mean SDI and ADI were 61.5 ± 28.0 and 7.7 ± 2.2, respectively. 28.1% of patients (n = 18) were diagnosed with primary cancer for the first time while 39.1% of patients (n = 25) were diagnosed with metastatic cancer for the first time. During index hospitalization, 37.5% of patients (n = 24) received palliative care consult. The 3-month, 6-month, and all-time mortality rates were 26.7% (n = 17), 39.5% (n = 23), and 50% (n = 32), respectively, with 10.9% of patients (n = 7) dying during their admission. Payor plan was significant at 3 months ( P = 0.02), and palliative consultation was significant at 3 months ( P = 0.007) and 6 months ( P = 0.03). No notable association was observed with SDI and ADI in quantiles or as continuous variables. DISCUSSION: In this study, 28.1% of patients were diagnosed with cancer for the first time. Three-month and 6-month mortality rates for patients undergoing surgery were 26.7% and 39.5%, respectively. Furthermore, mortality was markedly associated with palliative care consultation and insurance status, but not with SDI and ADI. LEVEL OF EVIDENCE: Retrospective case series, Level III evidence.

A Comparison of Prognostic Models to Facilitate Surgical Decision-Making for Patients With Spinal Metastatic Disease.

STUDY DESIGN: Retrospective cohort. OBJECTIVE: Compare the performance of and provide cutoff values for commonly used prognostic models for spinal metastases, including Revised Tokuhashi, Tomita, Modified Bauer, New England Spinal Metastases Score (NESMS), and Skeletal Oncology Research Group model, at three- and six-month postoperative time points. SUMMARY OF BACKGROUND DATA: Surgery may be recommended for patients with spinal metastases causing fracture, instability, pain, and/or neurological compromise. However, patients with less than three to six months of projected survival are less likely to benefit from surgery. Prognostic models have been developed to help determine prognosis and surgical candidacy. Yet, there is a lack of data directly comparing the performance of these models at clinically relevant time points or providing clinically applicable cutoff values for the models. MATERIALS AND METHODS: Sixty-four patients undergoing surgery from 2015 to 2022 for spinal metastatic disease were identified. Revised Tokuhashi, Tomita, Modified Bauer, NESMS, and Skeletal Oncology Research Group were calculated for each patient. Model calibration and discrimination for predicting survival at three months, six months, and final follow-up were evaluated using the Brier score and Uno's C, respectively. Hazard ratios for survival were calculated for the models. The Contral and O'Quigley method was utilized to identify cutoff values for the models discriminating between survival and nonsurvival at three months, six months, and final follow-up. RESULTS: Each of the models demonstrated similar performance in predicting survival at three months, six months, and final follow-up. Cutoff scores that best differentiated patients likely to survive beyond three months included the Revised Tokuhashi score=10, Tomita score=four, Modified Bauer score=three, and NESMS=one. CONCLUSION: We found comparable efficacy among the models in predicting survival at clinically relevant time points. Cutoff values provided herein may assist surgeons and patients when deciding whether to pursue surgery for spinal metastatic disease. LEVEL OF EVIDENCE: 4.

The ISSG-AO Complication Intervention Score, but Not Major/Minor Designation, is Correlated With Length of Stay Following Adult Spinal Deformity Surgery.

STUDY DESIGN: Retrospective review. OBJECTIVES: The International Spine Study Group-AO (ISSG-AO) Adult Spinal Deformity (ASD) Complication Classification System was developed to improve classification, reporting, and study of complications among patients undergoing ASD surgery. The ISSG-AO system classifies interventions to address complications by level of invasiveness: grade zero (none); grade 1, mild (e.g., medication change); grade 2, moderate (e.g., ICU admission); grade 3, severe (e.g., reoperation related to surgery of interest). To evaluate the efficacy of the ISSG-AO ASD Complication Classification System, we aimed to compare correlations between postoperative length of stay (LOS) and complication severity as classified by the ISSG-AO ASD and traditional major/minor complication classification systems. METHODS: Patients age ≥18 in a multicenter ASD database who sustained in-hospital complications were identified. Complications were classified with the major/minor and ISSG-AO systems and correlated with LOS using an ensemble-based machine learning algorithm (conditional random forest) and a generalized linear mixed model. RESULTS: 490 patients at 19 sites were included. 64.9% of complications were major, and 35.1% were minor. By ISSG-AO classification, 20.4%, 66.1%, 6.7%, and 6.7% were grades 0-3, respectively. ISSG-AO complication grading demonstrated significant correlation with LOS, whereas major/minor complication classification demonstrated inverse correlation with LOS. In conditional random forest analysis, ISSG-AO classification had the greatest relative importance when assessing correlations across multiple variables with LOS. CONCLUSIONS: The ISSG-AO system may help identify specific complications associated with prolonged LOS. Targeted interventions to avoid or reduce these complications may improve ASD surgical quality and resource utilization.

Ossification of the Posterior Longitudinal Ligament: Pathophysiology, Diagnosis, and Management.

Ossification of the posterior longitudinal ligament (OPLL) occurs as heterotopic bone forms in the posterior longitudinal ligament, resulting in neural compression, myelopathy, and radiculopathy. OPLL is most commonly observed in East Asian populations, with prevalence rates of 1.9% to 4.3% reported in Japan. OPLL rates are lower in North American and European patients, with reported prevalence of 0.1% to 1.7%. Patients typically develop symptoms due to OPLL in their cervical spines. The etiology of OPLL is multifactorial, including genetic, metabolic, and anatomic factors. Asymptomatic or symptomatic patients with OPLL can be managed nonsurgically, whereas patients with neurologic symptoms may require surgical decompression from an anterior, posterior, or combined approach. Surgical treatment can provide notable improvement in neurologic function. Surgical decision making accounts for multiple factors, including patient comorbidities, neurologic status, disease morphology, radiographic findings, and procedure complication profiles. In this study, we review OPLL epidemiology and pathophysiology, clinical features, radiographic evaluation, management, and complications.

Sarcopenia Is an Independent Risk Factor for Proximal Junctional Disease Following Adult Spinal Deformity Surgery.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: Sarcopenia is a risk factor for medical complications following spine surgery. However, the role of sarcopenia as a risk factor for proximal junctional disease (PJD) remains undefined. This study evaluates whether sarcopenia is an independent predictor of proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) following adult spinal deformity (ASD) surgery. METHODS: ASD patients who underwent thoracic spine to pelvis fusion with 2-year clinical and radiographic follow-up were reviewed for development of PJK and PJD. Average psoas cross-sectional area on preoperative axial computed tomography or magnetic resonance imaging at L4 was recorded. Previously described PJD risk factors were assessed for each patient, and multivariate linear regression was performed to identify independent risk factors for PJK and PJF. Disease-specific thresholds were calculated for sarcopenia based on psoas cross-sectional area. RESULTS: Of 32 patients, PJK and PJF occurred in 20 (62.5%) and 12 (37.5%), respectively. Multivariate analysis demonstrated psoas cross-sectional area to be the most powerful independent predictor of PJK (P = .02) and PJF (P = .009). Setting ASD disease-specific psoas cross-sectional area thresholds of <12 cm2 in men and <8 cm2 in women resulted in a PJF rate of 69.2% for patients below these thresholds, relative to 15.8% for those above the thresholds. CONCLUSIONS: Sarcopenia is an independent, modifiable predictor of PJK and PJF, and is easily assessed on standard preoperative computed tomography or magnetic resonance imaging. Surgeons should include sarcopenia in preoperative risk assessment and consider added measures to avoid PJF in sarcopenic patients.

Gender, Racial, and Ethnic Differences in the Utilization of Cervical Disk Replacement for Cervical Radiculopathy.

INTRODUCTION: Cervical radiculopathy (CR) is commonly treated by spine surgeons, with surgical options including anterior cervical diskectomy and fusion (ACDF) and cervical disk replacement (CDR). CDR is a motion-sparing alternative to ACDF and was approved by the US FDA in 2007. CDR utilization has increased because evidence has emerged demonstrating its long-term efficacy. Despite CDR's efficacy, studies have suggested that socioeconomic factors may influence which patients undergo CDR versus ACDF. Our objective was to determine whether gender, racial, and ethnic disparities exist in the utilization of CDR versus ACDF for CR. METHODS: Patients age ≥18 years undergoing elective CDR or ACDF for CR between 2017 and 2020 were identified in the Vizient Clinical Database. Proportions of patients undergoing CDR and ACDF, as well as their comorbidities, complications, and outcomes, were compared by sex, race, and ethnicity. Bonferroni correction was done for multiple comparisons. RESULTS: A total of 7,384 patients, including 1,427 undergoing CDR and 5,957 undergoing ACDF, were reviewed. Black patients undergoing surgical treatment of CR were less likely to undergo CDR than ACDF, had a longer length of stay, and had higher readmission rates, while Hispanic patients had higher complication rates than non-Hispanic patients. DISCUSSION: Important racial and ethnic disparities exist in CR treatment. Interventions are necessary to ensure equal access to spine care by reducing barriers, such as underinsurance and implicit bias. LEVEL OF EVIDENCE: IV (Case Series).

Patient Characteristics, Injury Types, and Costs Associated with Secondary Over-Triage of Isolated Cervical Spine Fractures.

STUDY DESIGN: Retrospective cohort. OBJECTIVE: To aim of this study was to identify patient variables, injury characteristics, and costs associated with operative and non-operative treatment following inter-facility transfer of patients with isolated cervical spine fractures. SUMMARY OF BACKGROUND DATA: Patients with isolated cervical spine fractures are subject to inter-facility transfer for surgical assessment, yet are often treated nonoperatively. The American College of Surgeons' benchmark rate of "secondary over-triage" is <50%. Identifying patient and injury characteristics as well as costs associated with treatment following transfer of patients with isolated cervical spine fractures may help reduce rates of secondary over-triage and healthcare expenditures. METHODS: Patients transferred to a Level-1 trauma center with isolated cervical spine fractures between January 2015 and September 2020 were identified. Patient demographics, comorbidities, insurance data, injury characteristics, imaging workup, treatment, and financial data were collected for all patients. Multivariable logistic regression models were constructed to identify patient and injury characteristics associated with surgical treatment. RESULTS: Nearly 75% of patients were treated non-operatively. Over 97% of transfers were accepted by the general surgery trauma service. Multivariable modeling found that higher BMI, presence of any neurologic deficit including spinal cord or isolated spinal nerve root injuries, present smoking status, or cervical spine magnetic resonance imaging obtained post-transfer, were associated with surgical treatment for isolated cervical spine fractures. Among patients with type II dens fractures, increased fracture displacement was associated with surgical treatment. Median charges to patients treated operatively and nonoperatively were $380,890 and $90,734, respectively. Median hospital expenditures for patients treated operatively and nonoperatively were $55,115 and $12,131, respectively. CONCLUSION: A large proportion of patients with isolated cervical spine fractures are subject to over-triage. Injury characteristics are important for determining need for surgical treatment, and therefore interfacility transfer. Improving communication with spine surgeons when deciding to transfer patients may significantly reduce health care costs and resource use.Level of Evidence: 4.

Association of findings on preoperative extension lateral cervical radiography with osteotomy type, approach, and postoperative cervical alignment after cervical deformity surgery.

OBJECTIVE: The authors' objective was to determine whether preoperative lateral extension cervical spine radiography can be used to predict osteotomy type and postoperative alignment parameters after cervical spine deformity surgery. METHODS: A total of 106 patients with cervical spine deformity were reviewed. Radiographic parameters on preoperative cervical neutral and extension lateral radiography were compared with 3-month postoperative radiographic alignment parameters. The parameters included T1 slope, C2 slope, C2-7 cervical lordosis, cervical sagittal vertical axis, and T1 slope minus cervical lordosis. Associations of radiographic parameters with osteotomy type and surgical approach were also assessed. RESULTS: On extension lateral radiography, patients who underwent lower grade osteotomy had significantly lower T1 slope, T1 slope minus cervical lordosis, cervical sagittal vertical axis, and C2 slope. Patients who achieved more normal parameters on extension lateral radiography were more likely to undergo surgery via an anterior approach. Although baseline parameters were significantly different between neutral lateral and extension lateral radiographs, 3-month postoperative lateral and preoperative extension lateral radiographs were statistically similar for T1 slope minus cervical lordosis and C2 slope. CONCLUSIONS: Radiographic parameters on preoperative extension lateral radiography were significantly associated with surgical approach and osteotomy grade and were similar to those on 3-month postoperative lateral radiography. These results demonstrated that extension lateral radiography is useful for preoperative planning and predicting postoperative alignment.

Establishing an Ehlers-Danlos Syndrome Clinic: Lessons Learned.

In a large academic medical center, patient requests from the community and internal referrals for evaluation of suspected hypermobility conditions were being denied consultation because services specific to this condition were not available. We identified this gap and developed a comprehensive evaluation for this unique patient population. The objective of this paper is to demonstrate a solution for improving outcomes in a neglected patient population by establishing an innovative outpatient clinic specifically tailored for patients with EDS. We describe the lessons learned on establishing a specialty clinic for treating patients with hypermobility syndromes including hypermobile Ehlers-Danlos syndrome (hEDS) and hypermobile syndrome disorder (HSD). Findings were collected from a patient focus group that was instrumental in understanding common care gaps. We document the firsthand perspective of three patients presenting with hypermobility accompanied by joint pain and denote the complicated state of healthcare in recognizing and treating this condition. A summary of patient demographics and characteristics was collected from patients seen in the clinic from November 14, 2019 to April 13, 2021. The firsthand accounts illustrate the challenges faced in treating this condition and the need for, and success of, this clinic using a coordinated care model. Demographics reveal a primarily white female population under the age of 50 with many comorbidities. Genetic testing was largely negative, with more patients diagnosed with HSD than hEDS. Our shared experience of launching a successful EDS clinic may assist other clinicians in establishing similar care models.

Surgical Factors and Treatment Severity for Perioperative Complications Predict Hospital Length of Stay in Adult Spinal Deformity Surgery.

STUDY DESIGN: Retrospective review of prospectively collected multicenter registry data. OBJECTIVE: The aim of this study was to determine whether surgical variables and complications as graded by treatment severity impact postoperative hospital length of stay (LOS). SUMMARY OF BACKGROUND DATA: Surgical treatment can substantially improve quality of life for patients with adult spinal deformity (ASD). However, surgical treatment is associated with high complication rates, which may impact hospital LOS. Classifying complications by severity of subsequent treatment may allow surgeons to better understand complications and predict their impact on important outcome metrics, including LOS. METHODS: Patients enrolled in a multicenter, prospectively enrolled database for ASD were assessed for study inclusion. Complications were graded based on intervention severity. Associations between LOS, complication intervention severity, and surgical variables (fusion length, use of interbody fusion, use of major osteotomy, primary versus revision surgery, same day vs. staged surgery, and surgical approach), were assessed. Two multivariate regression models were constructed to assess for independent associations with LOS. RESULTS: Of 1183 patients meeting inclusion criteria, 708 did not and 475 did experience a perioperative complication during their index hospitalization, with 660 and 436 included in the final cohorts, respectively. Among those with complications, intervention severities included 14.9% with no intervention, 68.6% with minor, 8.9% with moderate, and 7.6% with severe interventions. Multivariate regression modeling demonstrated that length of posterior fusion, use of major osteotomy, staged surgery, and severity of intervention for complications were significantly associated with LOS. CONCLUSION: Careful selection of surgical factors may help reduce hospital LOS following surgery for ASD. Classification of complications by treatment severity can help surgeons better understand and predict the implications of complications, in turn assisting with surgical planning and patient counseling.Level of Evidence: 4.

Assessment of Adult Spinal Deformity Complication Timing and Impact on 2-Year Outcomes Using a Comprehensive Adult Spinal Deformity Classification System.

STUDY DESIGN: Retrospective review of prospectively collected multicenter registry data. OBJECTIVE: To identify rates and timing of postoperative complications in adult spinal deformity (ASD) patients, the impact of complication type and timing on health related quality of life (HRQoL) outcomes, and the impact of complication timing on readmission and reoperation rates. Better understanding of complication timing and impact on HRQoL may improve patient selection, preoperative counseling, and postoperative complication surveillance. SUMMARY OF BACKGROUND DATA: ASD is common and associated with significant disability. Surgical correction is often pursued, but is associated with high complication rates. The International Spine Study Group, AO Spinal Deformity Forum, and European Spine Study Group have developed a new complication classification system for ASD (ISSG-AO spine complications classification system). METHODS: The ISSG-AO spine complications classification system was utilized to assess complications occurring over the 2-year postoperative time period amongst a multicenter, prospectively enrolled cohort of patients who underwent surgery for ASD. Kaplan-Meier survival curves were established for each complication type. Propensity score matching was performed to adjust for baseline disability and comorbidities. Associations between each complication type and HRQoL, and reoperation/readmission and complication timing, were assessed. RESULTS: Of 584 patients meeting inclusion criteria, cardiopulmonary, gastrointestinal, infection, early adverse events, and operative complications contributed to a rapid initial decrease in complication-free survival. Implant-related, radiographic, and neurologic complications substantially decreased long-term complication-free survival. Only radiographic and implant-related complications were significantly associated with worse 2-year HRQoL outcomes. Need for readmission and/or reoperation was most frequent among those experiencing complications after postoperative day 90. CONCLUSION: Surgeons should recognize that long-term complications have a substantial negative impact on HRQoL, and should carefully monitor for implant-related and radiographic complications over long-term follow-up.Level of Evidence: 4.

Orthopaedic In-Training Examination: History, Perspective, and Tips for Residents.

Introduced in 1963, the orthopaedic in-training examination (OITE) is a standardized, national test administered annually to orthopaedic residents by the American Academy of Orthopaedic Surgeons. The examination consists of 275 multiple-choice questions that cover 11 domains of orthopaedic knowledge, including basic science, foot and ankle, hand, hip and knee, oncology, pediatrics, shoulder and elbow, spine, sports medicine, trauma, and practice management. The OITE has been validated and is considered predictive of success in both orthopaedic surgery residency and on the American Board of Orthopaedic Surgery part I examination. This article provides a historical overview of the OITE, details its current structure and scoring system, and reviews currently available study materials. For examination preparation, the residents are encouraged to (1) start the examination preparation early, (2) practice on old OITE or self-assessment examination questions, (3) focus on the questions answered incorrectly, (4) focus on comprehension over memorization, and (5) recognize and avoid burnout. Finally, the residents should have a systemic way of approaching each multiple-choice question, both during practice and on the actual examination.
