Short-Term Morbidity and Mortality after Distal Femur Open Reduction Internal Fixation in the Geriatric Population.

OBJECTIVE: Distal femur fractures remain a significant cause of morbidity and mortality for elderly patients. There is a lack of large population studies investigating short-term outcomes after distal femur c in elderly patients. The purpose of this study is to assess the incidence of and risk factors for various short-term outcomes after distal femur open reduction internal fixation (ORIF) in the geriatric population. METHODS: The American College of Surgeons' National Surgical Quality Improvement Program (NSQIP) database was used to identify all primary distal femur ORIF cases in patients 60+ years old between January 1, 2015 and December 31, 2020 using Current Procedural Terminology (CPT) codes 27511, 27513, and 27514. Demographic, medical, and surgical variables were extracted for all patients. Propensity score matching was used to match cases in the two age groups based on various demographic and medical comorbidity variables. Several 30-day outcome measures were compared between the 60-79-year-old and 80+-year-old groups both before and after matching. Subsequent multivariate logistic regression was used to identify independent risk factors for 30-day outcome measures in the matched cohort. RESULTS: A total of 2913 patients were included in the final cohort: 1711 patients in the 60-79-year-old group and 1202 patients in the 80+-year-old group. Most patients were female (n = 2385; 81.9%). Prior to matching, the older group had a higher incidence of 30-day mortality (1.9% vs. 6.2%), readmission (3.7% vs. 9.7%, p = 0.024), and non-home discharge (74.3% vs. 89.5%, p < 0.001). Additionally, the older group had a higher rate of blood loss requiring transfusion (30.9% vs. 42.3%, p < 0.001) and medical complications (10.4% vs. 16.4%, p < 0.001), including myocardial infarction (0.7% vs. 2.7%, p < 0.001), pneumonia (2.7% vs. 4.6%, p = 0.008), and urinary tract infection (4.1% vs. 6.1%, p = 0.0188). After matching, the older group consistently had a higher incidence of mortality, non-home-discharge, blood loss requiring transfusion, and myocardial infarction. Various independent risk factors were identified for 30-day morbidity and mortality, including American Society of Anesthesiologists (ASA) classification, body mass index (BMI) status, operative duration, and certain medical comorbidities. CONCLUSION: Geriatric patients undergoing distal femur ORIF are at significant risk for 30-day morbidity and mortality. After matching, octogenarians and older patients specifically are at increased risk for mortality, non-home discharge, and surgical complications compared to patients aged 60-79 years old. Multiple factors, such as BMI status, ASA classification, operative time, and certain medical comorbidities, are independently associated with poor 30-day outcomes.

Does Fracture Pattern Really Predict Displacement of LC1 Sacral Fractures?

BACKGROUND: Operative management of minimally displaced lateral compression type-1 (LC1) pelvic ring injuries remains controversial. We aimed to assess the proportion of LC1 pelvic fractures that displaced following nonoperative management as a function of specific ring fracture patterns, and we quantified the magnitude of this displacement. METHODS: A retrospective review of the billing registry of a level-I trauma center was performed. Two hundred and seventy-three patients with a high-energy LC1 pelvic ring fracture and <5 mm of sacral displacement were included. The fracture pattern was characterized with use of computed tomography (CT) scans and radiographs. Absolute and interval pelvic ring displacement were quantified with use of previously described methodology. RESULTS: Thirty-five pelvic ring injuries (13%) were displaced. The rate of displacement was 31% (15 of 49) for LC1 injuries involving a complete sacral fracture and bilateral ramus fractures, 12% (7 of 58) for injuries involving a complete sacral fracture and a unilateral ramus fracture, and 10% (5 of 52) for injuries involving an incomplete sacral fracture and bilateral ramus fractures. In displaced injuries, the average interval displacement was 4.2 mm (95% confidence interval [CI], 1.8 to 6.8) and the final displacement was 9.9 mm ± 4.2 mm. CONCLUSIONS: Our study suggests that fracture characteristics can be used to predict the likelihood of displacement of LC1 fractures that are treated without surgery. To our knowledge, the present study is the first to describe the magnitude of displacement that may occur in association with LC1 pelvic ring injuries that are treated nonoperatively; however, further studies are needed to determine the clinical impact of this displacement.

Effects of Delayed Hip Fracture Surgery on Severely Ill Patients: Defining the Time to Medical Optimization.

BACKGROUND: Patients with multiple comorbidities often have delayed hip fracture surgery due to medical optimization. The goal of this study is to identify the allowable time for medical optimization in severely ill hip fracture patients. METHODS: The 2016-2019 NSQIP database was used to identify patients over age 60 with ASA classification scores 3 and 4 for severe and life-threatening systemic diseases. Patients were divided into immediate (<24 hours), early (24-48 hours), or late (>48 hours) groups based on time to surgery (TTS). Risk-adjusted multivariable logistic regressions were conducted to compare relationships between 30-day postoperative outcomes and TTS. RESULTS: 43,071 hip fracture cases were analyzed for the purposes of this study. Compared to patients who underwent surgery immediately, patients who had surgeries between 24 and 48 hours were associated with higher rates of pneumonia (OR 1.357, CI 1.194-1.542), UTIs (OR 1.155, CI 1.000-1.224), readmission (OR 1.136, CI 1.041-1.240), postoperative LOS beyond 6 days (OR 1.249, CI 1.165-1.340), and mortality (OR 1.205, CI 1.084-1.338). Patients with surgeries delayed beyond 48 hours were associated with higher rates of CVA (OR 1.542, CI 1.048-2.269), pneumonia (OR 1.886, CI 1.611-2.209), UTIs (OR 1.546, CI 1.283-1.861), readmission (OR 1.212, CI 1.074-1.366), postoperative LOS beyond 6 days (OR 1.829, CI 1.670-2.003), and mortality (OR 1.475, CI 1.286-1.693) compared to patients with immediate surgery. DISCUSSION: Severely ill patients with the hip fracture may have a 24-hour window for medical optimization. Hip fracture surgery performed beyond 48 hours is associated with higher complication rates and mortality among those who are severely ill. Further prospective studies are warranted to examine the effects of early surgical intervention among severely ill patients.

Heterotopic Ossification Prophylaxis in Acetabular Fracture Surgery: A Systematic Review.

Heterotopic ossification (HO) following acetabular fracture surgery is relatively common. The purpose of this study was to perform a systematic review of the literature regarding HO rates following acetabular surgery and the effectiveness of the various prophylactic measures taken to prevent its occurrence. A search of PubMed, MEDLINE, and Cochrane Database of Systematic Reviews was performed using the search terms ("Acetabular" OR "Acetabulum") AND ("Heterotopic Ossification" OR "HO" OR "Ectopic Ossification"). Inclusion criteria included articles published in English reporting on HO in acetabular fracture surgery. Descriptive statistics were calculated with categorical data presented as frequency with percentages and continuous data as means. Standard weighted means were calculated for all parameters. Sixty-six articles were included in this study with a total of 5,028 patients. HO was identified in 1,511 (30%) of fractures. Indomethacin (27%) and radiation therapy (24%) demonstrated decreased rates of HO formation versus no prophylaxis (36%). In particular, rates of severe HO formation were substantially decreased with radiation therapy (3%) and indomethacin (7%) compared to no prophylaxis (18%). Indomethacin and radiation therapy both appear to decrease HO formation and severity without substantially increasing surgical morbidity.

Risk factors for loss to follow up of pelvis and acetabular fractures.

INTRODUCTION: Pelvic and acetabular fracture incidence is increasing worldwide for more than four decades. There is currently no evidence examining risk factors for loss to follow up in patients with these injuries. METHODS: Patients presenting with pelvic and/or acetabular fractures at our institution between 2015 and 2020 were included. Demographic, injury, treatment, and follow up information was included. Excluded patients were those who sustained a pathologic fracture, has a course of treatment prior to transfer to our centre, or expired prior to discharge. RESULTS: 446 patients, 263 with a pelvic ring injury, 172 with an acetabular fracture, and 11 with combined injuries were identified. 271 (61%) of patients in our cohort followed up in Orthopaedic clinic (p = 0.016). With an odds ratio of 2.134, gunshot wound mechanism of injury was the largest risk factor for loss to follow up (p = 0.031) followed by male sex (OR= 1.859) and surgery with general trauma surgery (OR=1.841). The most protective risk factors for follow up with Orthopaedic surgery were operatively treated pelvic and acetabular fractures (OR=0.239) and Orthopaedic Surgery as the discharging service (OR=0.372). DISCUSSION: Numerous risk factors exist for loss to follow up including male sex, ballistic mechanism, and discharging service. Investigation into interventions to improve follow up in these patients are warranted.

Orthopaedic Surgery Residency Program Websites: A Five-Year Update and the Rise of Social Media.

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

Arthroscopic Case Volumes Among Orthopaedic Surgery Residents and Orthopaedic Sports Medicine Fellows: An Analysis of ACGME Case Log Data.

Arthroscopic procedures are used to treat a multitude of disorders, but they can be technically demanding. These procedures are a fundamental aspect of orthopaedic surgery residency and surgical sports medicine fellowship. The goal of this study was to analyze the variability in arthroscopic case experience to better understand the disparities between various training programs and the opportunity for increased surgical case volume of an orthopaedic sports medicine fellowship. Resident and fellow case log reports were gathered from the Accreditation Council for Graduate Medical Education. Fellows reported 286% more arthroscopic cases in one year of fellowship than residents reported in five years of residency (554 cases vs. 193 cases, p < 0.0001). Fellows also performed 770% more arthroscopic hip procedures than residents (57 cases vs. 7 cases, p < 0.0001). There is a significant difference in arthroscopic case volume between residents and fellows. An orthopaedic sports medicine fellowship dramatically increases the arthroscopic experience of trainees.

Determining the Impact of the COVID-19 Pandemic on Hand Surgery Fellowship Education.

The purpose of this study is to report the impact of COVID-19 on hand surgery fellow learning and preparedness for practice. A multi-dimensional questionnaire was distributed to current hand fellows and fellowship directors across the United States. Survey questions included fellowship location, institutional response, impact on practice, education and job search. Thirty-two hand surgery fellows and 14 fellowship directors completed the survey. Of fellows, 59% reported a greater than 75% decrease in case volume. Mean hours worked per week per fellow decreased by 52%. All fellowship directors and 94% of fellows did not expect COVID-19 to impact their ability to graduate, and nearly all fellows felt prepared to start practice after fellowship training. However, many fellows expressed concern about job opportunities. The work hours and exposure of hand surgery fellows to elective surgical cases have been adversely impacted by COVID-19. Nevertheless, current hand fellows feel prepared to enter practice. (Journal of Surgical Orthopaedic Advances 31(1):048-052, 2022).

Incidence, risk factors and clinical implications of postoperative urinary tract infection in geriatric hip fractures.

INTRODUCTION: Postoperative urinary tract infection (UTI) is common in geriatric patients; however, little is known about the impact of UTI in orthopedic trauma. The present study was designed to determine the risk factors and clinical impact of postoperative urinary tract infection (UTI) in acute geriatric hip fractures. PATIENTS AND METHODS: Geriatric patients (≥65 years of age) undergoing hip fracture surgery were identified within the American College of Surgeons National Surgical Quality Improvement Program between 2016 and 2019. Patients presenting with UTI at the time of surgery were excluded. Baseline characteristics and outcomes were compared between patients with and without postoperative UTI. Multivariate logistic regression was performed, controlling for potential confounders. RESULTS: A total of 46,263 patients included in the study. Overall, 1,397 (3.02%) patients had postoperative UTI. Patients who developed postoperative UTI had higher rates of pneumonia (6.44% vs. 3.76%, p < 0.001), DVT (2.22% vs. 1.04%, p < 0.001), sepsis (7.73% vs. 0.62%, p < 0.001), and more frequently experienced postoperative hospital lengths of stay exceeding 6 days (37.94% vs. 20.33%, p < 0.001). Hospital readmission occurred more frequently in patients with postoperative UTI (24.55% vs. 7.85%, p < 0.001), but surprisingly, these patients had a lower mortality rate (1.36% vs. 2.2%, p < 0.001). Adjusted analysis demonstrated the following variables associated with postoperative UTI: age ≥ 85 (OR = 1.37, 95%CI = 1.08 - 1.73), ASA class ≥ 3 (OR = 1.59, 95%CI = 1.21 - 2.08,), chronic steroid use (OR = 1.451, 95%CI = 1.05 - 1.89), blood transfusion (OR = 1.24, 95%CI = 1.05 - 1.48), and >2 days delay from admission to operation (OR = 1.37, 95%CI = 1.05 - 1.79). Postoperative UTI was significantly associated with sepsis (OR = 7.65, 95%CI = 5.72 - 10.21), postoperative length of stay >2 days (OR = 1.83, 95%CI = 1.07 - 3.13), and readmission (OR = 3, 95%CI = 2.54 - 3.55). CONCLUSIONS: In our study, postoperative UTI was found in 3% of geriatric hip fracture patients. Predictors of postoperative UTI were age ≥ 85, ASA class ≥ 3, chronic steroid use, blood transfusion, and time to operation > 2 days from admission. Results showed that postoperative UTI is independently associated with sepsis, postoperative length of stay beyond 2 days, and hospital readmission. To diminish the risk of UTI and its consequences, we recommend operating geriatric hip fractures in 24-48 hours after admission.

Comparison of Extramedullary and Intramedullary Implants for Stable Intertrochanteric Fractures: Have We Swung the Pendulum Too Far the Other Way?

INTRODUCTION: Although intramedullary implants are commonly used to treat stable intertrochanteric (IT) fractures, there is a lack of evidence to demonstrate their superiority over extramedullary implants in treating these fractures. The purpose of this study was to compare short-term outcomes (<30 days) between intramedullary and extramedullary implants in patients with closed nondisplaced stable IT fractures. METHODS: Patients with closed nondisplaced stable IT fractures were identified from the American College of Surgeons National Surgical Quality Improvement Program database between 2016 and 2019. Patients who either underwent extramedullary implant or intramedullary implant fixation were selected for this analysis. Postoperative outcomes included transfusion, surgical complications (stroke, myocardial infarction, venous thromboembolism, pneumonia, renal failure/insufficiency, surgical site infection, urinary tract infections, and sepsis), weight-bearing on postoperative day 1, discharge destination, place of residence at 30 days after the operation, days from operation to discharge, readmission related to the index procedure, any readmission, revision surgery, and mortality. RESULTS: Of the 3,244 cases identified for the study, 2,521 (77.7%) underwent intramedullary nailing (IMN). Based on adjusted multivariable analysis, surgical complications between the two intervention groups were not statistically significantly (odds ratio [OR] 1.142; confidence interval [CI], 0.838 to 1.558; P = 0.4). However, patients who underwent IMN were associated with higher rates of blood transfusions (OR, 1.35, CI, 1.042 to 1.748, P = 0.023), more likely discharged to a place other than home (OR, 1.372, CI, 1.106 to 1.700, P = 0.004), and more likely to get readmitted (OR, 1.783, CI, 1.157 to 2.75, P = 0.009). Patients treated with IMN were associated with lower postoperative length of stay (OR 0.982, CI 0.967 to 0.998, P = 0.030). DISCUSSION: Our study found that extramedullary implants were associated with lower transfusions rates, lower readmissions, and better patient disposition. We recommend surgeons to consider extramedullary implants when treating stable IT fractures, especially if the patient is anemic or at high risk for hospital readmission. LEVEL OF EVIDENCE: Level III. Retrospective cohort study.

Clinical Outcomes and Surgical Complications Among Patients with Bleeding Disorders After Acute Hip Fracture Surgery.

OBJECTIVE: To compare short-term (≤30 days) outcomes of hip fracture between patients with and without bleeding disorders. DESIGN: Retrospective database review. SETTING: The study setting included hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program database. PATIENTS: Patients with acute hip fractures were identified from the National Surgical Quality Improvement Program database between 2016 and 2019. INTERVENTION: Open reduction internal fixation or hemiarthroplasty. MAIN OUTCOME MEASUREMENTS: Mortality, readmission, reoperation, length of stay, and complication were main outcome measurements. RESULTS: There were 63,718 patients undergoing hip surgery, and 16.0% had a bleeding disorder. After adjusting for confounders, multivariable regression models showed that cases with bleeding disorders were associated with higher rates of transfusion [odds ratio (OR) 1.404; confidence interval (CI), 1.335-1.479], myocardial infarction (OR 1.367; CI, 1.190-1.572), pneumonia (OR 1.193; CI, 1.078-1.321), renal failure (OR 1.843; CI, 1.363-2.491), surgical site infections (OR 1.429; CI, 1.185-1.175), sepsis (OR 1.25; CI, 1.034-1.511), and readmission (OR 1.314; CI, 1.224-1.408). However, bleeding disorders were not associated with mortality (OR 0.947; CI, 0.866-1.036) or reoperation (OR 1.061; CI, 0.925-1.220). CONCLUSIONS: Hip fracture surgery in patients with bleeding disorders is not associated with higher risks of short-term mortality or reoperation. However, special consideration should be taken when calculating preoperative risks of complications among bleeding disorder patients. LEVEL OF EVIDENCE: Prognostic Level III.

The Geriatric Nutritional Risk Index Is an Independent Predictor of Adverse Outcomes for Total Joint Arthroplasty Patients.

BACKGROUND: Malnutrition affects patient outcomes after total joint arthroplasty (TJA). Although hypoalbuminemia has been used as a surrogate, there is no unanimous method for screening and assessing malnutrition. This study aimed to determine if malnutrition, as defined by the Geriatric Nutritional Risk Index (GNRI), is independently correlated with short-term (<30 days) postoperative complications and prognosis in patients undergoing TJA. METHODS: The 2016-2019 American College of Surgeons National Surgical Quality Improvement Program was queried for all patients aged >65 years who underwent TJA. Based on GNRI value, patients were divided into 3 groups: normal nutrition (GNRI >98), moderate malnutrition (GNRI 92-98), and severe malnutrition (GNRI <92). After adjusting for potential confounders, multivariable regression models were used to analyze the association between GNRI and patient outcomes. RESULTS: A total of 191,087 patients were included in the study. Prevalence of malnutrition based on body mass index (<18.5 kg/m2), albumin (<3.5 mg/dL), and GNRI (≤98) was 0.41% (784), 4.17% (7975), and 15.83% (30,258). Adjusted analysis showed that compared with normal nutrition, moderate and severe malnutrition status were associated with a higher rate of transfusion, readmission, and postoperative length of stay over 8 days (P < .05). Severe malnutrition was also associated with pneumonia, surgical site infection, urinary tract infection, sepsis, and revision surgery (P < .05). CONCLUSION: Malnutrition, as defined by GNRI, is an independent predictor of adverse outcomes after TJA, including 30-day readmission, revision surgery, and increased length of stay. GNRI can be used to routinely screen and assess patient nutritional status before TJA and counsel patients and families appropriately. LEVEL OF EVIDENCE: Level 3: Retrospective Cohort Study.

Accuracy of Radiographic Displacement Measurement in a Pelvic Ring Injury Model.

BACKGROUND: Pelvic ring injury outcome studies rely on radiographic assessment. To date, no study investigates the accuracy of radiographic measurement. The aim of this study was to assess the accuracy and interobserver reliability of pelvic ring displacement measurement in an injury model. We hypothesize that current radiographic measurement methods do not accurately quantify the three-dimensional pelvic ring displacement. METHODS: Ten orthopaedic traumatologists evaluated 12 pelvic ring injury model displacements using AP, inlet, and outlet radiographs and axial CT images. Observers completed a survey of demographic and treatment approach strategies. Radiographic displacement measurements in axial, coronal, and sagittal planes were analyzed for accuracy using. Absolute displacement measurements were categorized with Matta and Tornetta grading system for Fleiss Kappa inter-reliability correlation evaluation. RESULTS: The mean age of orthopaedic traumatologists was 47.5 years (range 36 to 59) with a mean 15.3 years (range 4 to 27) of pelvic fracture surgery experience. Radiographic measurement of isolated uniplanar of pelvic displacement in axial, sagittal, or coronal plane alone was more accurate than multiplanar pelvic displacements with more than one plane of displacement, 6.6 ± 5.7 mm error compared with 9.6 ± 6.3 mm error, respectively (P = 0.0035). Measurement accuracy was greater with isolated coronal plane (4 ± 3.5 mm error) compared with isolated axial plane (9.9 ± 7.1 mm error) or isolated sagittal plane displacement (6.7 ± 4 mm error). Interrater reliability for the radiographic displacement measurement by observers showed an overall poor agreement with 0.24. CONCLUSION: Radiographic displacement measurement in these modeled pelvic ring injuries has notable inaccuracy among various measurement methods. Coronal and sagittal plane radiographic displacement measurements are more accurate compared with axial plane measurement. The reporting of radiographic displacement measurement outcomes in clinical research studies should be critically evaluated, and standardization of pelvic ring injury displacement may not be achievable with radiography. LEVEL OF EVIDENCE: Level V.

Fixed angle device comparison in young femoral neck fractures: Dynamic hip screw vs dynamic helical hip system.

INTRODUCTION: Femoral neck fractures in the young patient present a unique challenge. Most surgeons managing these injuries prefer a fixed angle implant, however these devices are fraught with problems. A dynamic hip screw (DHS) is one such fixed angle device that risks malreduction through rotational torque during screw insertion. To avoid this risk some surgeons utilize a dynamic helical hip system (DHHS), however little is known about the complication profile of this device. We hypothesized that the complication rate between these two devices would be similar. PATIENTS AND METHODS: All patients presenting to a single tertiary referral center with a femoral neck fracture were identified from a prospectively collected trauma database over an 11-year period. Patients were included if they were less than 60 years of age, treated with a DHS or DHHS, and had at least 6 months of follow-up. Demographic data, injury characteristics, and post-operative complications were obtained through chart review. Standard statistical comparisons were made between groups. A total of 77 patients met inclusion criteria. RESULTS: Average age of patients was 38 years (range: 18-59) and 56 (73%) were male. The DHS was used in 37 (48%) patients and the DHHS was used in 40 (52%) patients. Demographic data including average age, gender, body mass index, and smoking status did not differ between the groups. There were 29 (39%) total complications of interest (femoral neck shortening >5 mm, non-union requiring osteotomy, conversion to THA, and osteonecrosis. There were 19 (51%) complications in the DHS group and 10 (25%) in the DHHS group (p = 0.01, risk difference 25%, 95% CI 7-43). Comparisons of the individual complications about the DHS and DHHS cohort did not reach statistical significance for non-union (8% vs 3%) or THA (16% vs 13%) (p = 0.33, p = 0.64, respectively) but a difference was detected in the rate of shortening (27% vs 10%; p = 0.05). CONCLUSION: This study demonstrates a high risk of complication when managing young femoral neck fractures in line with prior literature. The major complication rate of non-union requiring osteotomy or fixation failure resulting in THA was no different between the two groups, but the rate of shortening was greater the DHS group. This data suggests the DHHS may be a suitable device to manage the young femoral neck fracture and without increased risk of complication.

Techniques for predicting and avoiding unintentional biplanar movements during iliosacral screw placement.

The technique for placing iliosacral screws typically involves the surgeon using an inlet and outlet view as the primary means for assessing the anteroposterior and craniocaudal position of the guidewire, respectively. However, because these views are rarely, if ever, orthogonal to one another, this technique will inevitably lead to unintentional biplanar movements. These unintentional movements, in turn, require correction, which can increase operating room and fluoroscopic time. Here we calculate the degree and magnitude of these unintentional movements. Additionally, we provide a simple technique for minimizing or eliminating them altogether.

A Current Update on Pelvifemoral Conditions That Should be in the Differential Diagnosis for Patients With Lower Extremity Radiculopathy.

Patients presenting to an outpatient spine clinic frequently report symptoms of low back pain with associated buttock, groin, and lower extremity pain. While many of these individuals suffer from lumbar spine radiculopathy, a number of different orthopedic pathologies can mimic these symptoms. Management depends substantially on a detailed history and physical examination, in addition to working from a broad list of differential diagnoses when evaluating these patients. It is imperative that spine practitioners have a comprehensive understanding of the differential diagnoses that may mimic those originating from the lumbar spine, especially when a patient's symptoms are atypical from classic radicular pain. Misdiagnosis can lead to unnecessary testing and treatment, while delaying an accurate clinical assessment and treatment plan. This review highlights common orthopedic diagnoses that may present similar to lumbar spine pathologies and the evidence-based evaluation of these conditions.

Evaluating the Early Impact of the COVID-19 Pandemic on Sports Surgery Fellowship Education.

Purpose The COVID-19 pandemic forced many hospitals to cancel elective surgeries to minimize the risk of viral transmission and ensure the availability of vital health resources. The unintended consequences of this action on the education and training of orthopaedic sports surgeons are unknown. The purpose of this study is to measure the impact of COVID-19 on orthopaedic sports surgery fellows, their education and training, and their readiness for practice. Methods A comprehensive survey was created and distributed to all U.S. fellows and fellowship directors registered with the American Orthopaedic Society for Sports Medicine. Responses were collected between April 22, 2020, and May 5, 2020. Results Fifty-one sports fellows and twenty-nine sports fellowship directors completed the survey. Over 80.4% of fellows reported a greater than 50% decrease in the case volume since the cessation of elective cases. Average hours worked per week decreased by 58.2% during the pandemic. Fellows reported completing an average of 324.6 ± 97.4 cases prior to the COVID-19 crisis and 86.0% expected to complete at least 11% to 25% fewer cases by graduation compared to previous fellows. 87.5% of fellows were not concerned about their ability to complete their fellowship training but more than one-third of fellows voiced concerns to their fellowship directors regarding their readiness for independent practice. Fellowship directors were generally not concerned that COVID-19 would prevent their fellows from completing the fellowship. At least 54.2% are somewhat concerned about the impact of COVID-19 on their future job opportunities. Conclusions The COVID-19 pandemic has universally affected work hours and case volume of sports fellows. Nevertheless, most sports fellows feel prepared to enter practice and are generally supported by the confidence of their fellowship directors. The results of this survey emphasize the importance of the fellowship year in sports training and highlight the future of online education and simulation as useful adjuncts.

The Quadrilateral Plate in Acetabular Fracture Surgery: What Is It and When Should It Be Addressed?

The quadrilateral plate (QP) is the relatively flat surface of bone in the true pelvis lying directly medial to the acetabulum. This surface is frequently involved in acetabular fractures. Elderly individuals, in particular, commonly sustain anterior column fractures with incomplete or complete posterior hemitransverse fracture lines with associated QP comminution. If QP fracture lines propagate through the superior weight-bearing surface of the acetabulum, the femoral head may displace medially, leading to poor outcomes if not addressed. Fortunately, the collective work of many orthopaedic surgeons has resulted in numerous effective methods for approaching, reducing, and stabilizing the QP and the diverse family of fractures which affect it. A thorough understanding of the QP, its anatomy, radiology, and techniques for fixation, is required to optimize patient outcomes.

Assessing the Early Impact of the COVID-19 Pandemic on Spine Surgery Fellowship Education.

STUDY DESIGN: This was a cross-sectional study. OBJECTIVE: The objective of this study is to report the impact of COVID-19 on spine surgery fellow education and readiness for practice. SUMMARY OF BACKGROUND DATA: COVID-19 has emerged as one of the most devastating global health crises of our time. To minimize transmission risk and to ensure availability of health resources, many hospitals have cancelled elective surgeries. There may be unintended consequences of this decision on the education and preparedness of current surgical trainees. MATERIALS AND METHODS: A multidimensional survey was created and distributed to all current AO Spine fellows and fellowship directors across the United States and Canada. RESULTS: Forty-five spine surgery fellows and 25 fellowship directors completed the survey. 62.2% of fellows reported >50% decrease in overall case volume since cancellation of elective surgeries. Mean hours worked per week decreased by 56.2%. Fellows reported completing a mean of 188.4±64.8 cases before the COVID-19 crisis and 84.1% expect at least an 11%-25% reduction in case volume compared with previous spine fellows. In all, 95.5% of fellows did not expect COVID-19 to impact their ability to complete fellowship. Only 2 directors were concerned about their fellows successfully completing fellowship; however, 32% of directors reported hearing concerns regarding preparedness from their fellows and 25% of fellows were concerned about job opportunities. CONCLUSIONS: COVID-19 has universally impacted work hours and case volume for spine surgery fellows set to complete fellowship in the middle of 2020. Nevertheless, spine surgery fellows generally feel ready to enter practice and are supported by the confidence of their fellowship directors. The survey highlights a number of opportunities for improvement and innovation in the future training of spine surgeons. LEVEL OF EVIDENCE: Level III.

The role of arthroscopy in bullet removal: A systematic review of the literature.

PURPOSE: The purpose of this study was to systematically review the literature to gain a greater understanding of the role and usage of arthroscopy in removal of retained bullet fragments. Secondarily, we intend to examine the level of evidence and methodologic quality of studies reporting on this topic. METHODS: A search of PubMed, MEDLINE, and Cochrane Database of Systematic Reviews was performed using the search terms ("Arthroscopic" OR "Arthroscopy") AND ("Bullet" OR "Gunshot" OR "Ballistic" OR "Removal"). Inclusion criteria included articles published in English reporting on arthroscopic or arthroscopically-assisted bullet removal. Studies lacking sufficient data to separate arthroscopic and open procedures were excluded. Level of evidence, study information (i.e., country, journal, etc.), and patient data was collected from each eligible article. The methodological index for non-randomized studies (MINORS) score were assigned to each article. RESULTS: A total of 2676 studies were identified in the initial search with 31 studies meeting criteria for inclusion in the study. Twenty-eight of the 31 studies were case reports. The MINORS score averaged 8.8 ± 1.5 (range 5-10) for included studies. Sixty-two patients were identified, the majority (94%) of whom were male with an average age of 36.2 ± 12.3 years. All 62 patients underwent successful arthroscopic bullet removal. One patient was reported to have a complication (compartment syndrome). Outcome measures were underreported in the majority of studies. CONCLUSIONS: Our study found that very little literature exists on the role of arthroscopy in bullet removal. Of this literature, no high-quality studies exist. Based on the limited existing literature, arthroscopy appears to be a safe, reliable alternative to open surgery for bullet removal. Potential benefits of arthroscopic bullet removal exist and warrant further investigation to further define the role of arthroscopy. LEVEL OF EVIDENCE: Level V.
