Unusual Arteriovenous Malformation in Total Hip Arthroplasty: Case Report of a Complicated Perioperative Course.

It is not common to encounter arteriovenous malformations (AVMs) during total hip arthroplasty (THA). We report the present case to draw attention to the possibility of an AVM during the direct anterior approach (DAA) for THA, which, if not borne in mind, may lead to the myriad of complications related to excessive bleeding. An 81-year-old female presented to the emergency department with a left femoral neck fracture. She elected to undergo a THA via the DAA. Abnormal appearing blood vessels were present near the ascending circumflex branches, which provided difficulty in achieving hemostasis. Excessive blood loss was noted, and the patient received one unit of packed red blood cells during the operation. Hemoglobin and hematocrit dropped in the days following surgery, requiring several additional transfusions of blood products. When the patient complained of progressive left leg swelling on postoperative day 3, a computed tomography revealed large hematomas within the left adductors and the left iliopsoas muscle. Active extravasation was identified arising from a branch of the left profunda femoral artery, as well as an arteriovenous fistula (AVF) in this area. Bleeding was controlled by selective endovascular coil embolization. As of current knowledge, this is the first reported intraoperative discovery of congenital arteriovenous malformation (AVM) with subsequent development of postoperative arteriovenous fistula and associated symptomatic hematomas in the setting of THA using the DAA. Early recognition and intervention of vascular malformations is essential in preventing potential limb- or life-threatening surgical complication.

Resumo Não é comum encontrar malformações arteriovenosas (MAV) durante a artroplastia total do quadril (ATQ). Relatamos o presente caso para chamar a atenção para a possibilidade de uma MAV durante a abordagem anterior direta (AAD) para ATQ, que se não for considerada, pode levar a uma miríade de complicações relacionadas ao sangramento excessivo. Uma mulher de 81 anos foi apresentada ao pronto-socorro com fratura no pescoço do fêmur esquerdo. Ela optou por se submeter a uma artroplastia total do quadril (ATQ) através da AAD. Vasos sanguíneos aparentemente anormais estavam presentes perto dos ramos circunflexos ascendentes, proporcionando dificuldade em alcançar hemostasia. A perda excessiva de sangue foi notada e a paciente recebeu uma unidade de glóbulos vermelhos embalados durante a operação. Hemoglobina e hematócrito caíram nos dias seguintes à cirurgia, exigindo várias transfusões adicionais de produtos sanguíneos. Quando a paciente reclamou de inchaço progressivo na perna esquerda no terceiro dia pós-operatório, a tomografia computadorizada revelou hematomas grandes dentro dos adutores esquerdos e do músculo iliopsoas esquerdo. A extravasão ativa foi identificada a partir de um ramo da artéria femoral esquerda, bem como de uma fístula arteriovenosa (FAV) nesta área. O sangramento foi controlado por embolização seletiva da bobina endovascular. A partir do conhecimento atual, esta é a primeira descoberta intraoperatória relatada de MAC congênita com desenvolvimento subsequente de FAV pós-operatória e hematomas sintomáticos associados no cenário de ATQ utilizando a AAD. O reconhecimento precoce e a intervenção de malformações vasculares são essenciais para prevenir possíveis complicações cirúrgicas de membros ou de risco de vida.

The Mechanism of Anterior Cruciate Ligament Injuries in the National Football League: A Systematic Video Review.

Introduction Anterior cruciate ligament (ACL) injuries are common among American football athletes, although few studies have performed video analyses of ACL injuries to better understand the injury mechanism. This work aims to characterize the mechanism of ACL injury during professional football competitions using video analysis. We hypothesize that football-specific injury trends will emerge, including high rates of contact injuries and associations with shallow knee and hip flexion angles (0°-30°). Methods Videos of professional football players suffering ACL injuries from 2007 to 2016 were analyzed. Injured players were identified using the injured reserve (IR) lists of the National Football League (NFL), and videos were discovered via a systematic Google search. Descriptive statistics and frequency analyses were performed on all variables using the Statistical Package for the Social Sciences (SPSS) version 23.0 (IBM SPSS Statistics, Armonk, NY, USA). Results Of the 429 ACL injuries identified, 53 (12%) videos were available. Deceleration was the most common injury maneuver, present in 32 (60%) athletes. Thirty-one (58%) players suffered contact injuries. Twenty-eight (53%) injuries demonstrated valgus collapse of the knee, and 26 (49%) had neutral knee rotation. Defensive backs (26%) and wide receivers (23%) were the most frequently injured positions. Conclusion Overall, we found that most ACL injuries had preceding contact, deceleration, shallow hip and knee flexion, and heel strike, and subsequent valgus collapse and neutral knee rotation. This understanding of American football-specific ACL tear mechanisms could help direct the focus of future injury prevention training modalities.

Radial nerve transection after ballistic humeral shaft fractures: A retrospective cohort study.

INTRODUCTION: Radial nerve palsy following fracture of the humeral shaft is common. However, the incidence of nerve transection in the setting of ballistic trauma is unknown. The purpose of this study was to estimate the incidence of radial nerve transection after ballistic fracture of the humerus. METHODS: Patients presenting to an urban, level-1 trauma center with a ballistic fracture of the humeral shaft were retrospectively reviewed. Patient demographics, clinical exam on presentation, and operative data were reviewed to determine the incidence of radial nerve palsy on initial examination, the incidence of operative treatment, the incidence of how frequently the nerve was directly visualized, and the incidence of radial nerve transection. RESULTS: One-hundred and thirteen ballistic humeral shaft fractures were identified. Of these, 30 (26.5%) patients had a complete radial nerve palsy on exam. Of patients with a radial nerve palsy, on exam 20 were taken to the operating room and the nerve was visualized in 17 of those cases. There 2 were partially lacerated nerves and 12 nerves were completely transected. Thus, in patients with a complete nerve deficit on examination who underwent operative treatment with nerve exploration, the rate of nerve transection was 70.6%. The lower bound rate of nerve transection for all patients with radial nerve palsy (assuming all unexplored nerves were intact) was 40.0%. CONCLUSION: The rate of nerve transection in patients with humerus shaft fractures with associated radial nerve palsies is likely higher than the rate of nerve transection in similar injuries caused by blunt mechanisms. The authors recommend early exploration and fixation of these injuries.

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.

Does Surgeon Compensation Differ by Implant Choice for the Treatment of Femoral Neck Fractures?

The objective of this study was to determine if physicians are compensated equally for the treatment of femoral neck fractures based on fixation method in a propensity score matched cohort of patients. The American College of Surgeons' National Surgical Quality Improvement Project (ACS NSQIP) database was queried for patients undergoing open reduction internal fixation (ORIF), hemiarthroplasty (HA), and total hip arthroplasty (THA) for femoral neck fractures. Exact matching was used to account for differences in patient-specific variables and underlying medical comorbidities. Total relative value units (RVU), operative time, RVU/minute, and reimbursement/minute were compared between the three procedures after exact matching to assess relative valuation. Propensity score matching resulted in a total of 4,581 patients eligible for final data analysis (1,527 patients in each treatment group). The groups were very well matched for age, sex, BMI, comorbidities, and American Society of Anesthesiologists (ASA) class (p > 0.99 for all). When dividing compensation by case duration, ORIF generated the most RVUs per minute (0.31 ± 0.19 or $11.01 ± 7.02) followed by THA (0.27 ± 0.14 or $9.86 ± 5.15) and HA (0.25 ± 0.1 or $8.99 ± 3.75; p<0.001 for all). This study shows that orthopaedic surgeons are compensated the most for ORIF followed by THA and HA for fixation of femoral neck fractures.

Outcomes of Iliac Wing Fractures: A Systematic Review of the Literature.

To review the literature on iliac wing fractures to assess outcomes of operative and nonoperative treatment. A search of PubMed, MEDLINE, and Cochrane Database of Systematic Reviews was performed. Articles reporting on iliac wing fractures without pelvic ring destabilization or intraarticular extension were included. Study information and patient data were collected, and a Methodological Index for Non-randomized Studies (MINORS) score was assigned to each article. In total, 19,363 articles were identified with 32 qualifying for inclusion. The articles included 131 patients with 133 fractures. The mean age was 43.6, and mean follow-up time was 41.9 months. Forty-eight (36%) fractures were treated operatively, and 85 (64%) were treated nonoperatively. Associated injuries included bowel injuries, other pelvic fractures, gunshot wounds, and arterial injuries. There is an absence of comparative studies between operative and nonoperative management of iliac wing fractures. Indications for operative management appear to depend on comminution, open fractures, and associated injuries. (Journal of Surgical Orthopaedic Advances 32(3):139-147, 2023).

A Review on Management of Insufficiency Fractures of the Pelvis and Acetabulum.

"Insufficiency fractures of the pelvis and acetabulum are occurring at increasing rates. Osteoporosis is the most prevalent risk fracture. Diagnosis begins with plain radiographs followed by advanced imaging with computed tomography and/or MRI. Pelvic ring fragility injuries are classified by the Fragility fractures of the pelvis system. Elderly acetabular fractures may be classified by the Letournel system. Management of these injuries is primarily nonoperative with early immobilization when allowed by fracture characteristics. When warranted, percutaneous fixation and open reduction internal fixation are options for both. Both acute and delayed total hip arthroplasty are options for acetabular fractures."

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.

Highly Cited Articles in Periacetabular Osteotomy Research.

Purpose: The aim of this study is to identify highly cited articles and examine trends and characteristics in research on periacetabular osteotomy. Materials and Methods: The 50 most highly cited articles on periacetabular osteotomy research were identified using Scopus. Data regarding article demographics and publication were collected from each article and an analysis was performed. Results: The mean citation count was 125±37. The article with the highest total citation count (796), five-year citation count (327), and five-year citation density (65/year) was reported by Reinhold Ganz. The five-year citation density showed strong correlation with total citation density (r=0.930, P<0.001). Reinhold Ganz, the most productive author, was listed on 13 articles in the cohort with 455 weighted citation points. Conclusion: This study provides a collection of articles examining periacetabular osteotomies and demonstrates that citation count can be regarded as an acceptable measure of the contemporary academic influence of an article.

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.

Characteristics and Trends of Highly Cited Articles in Calcaneus Fracture Research.

Background: Despite significant effort expended toward exploring fracture patterns, surgical timing, surgical approaches, and possible implants within the calcaneus fracture literature, treatment is still fraught with complications and controversy. This study aims to conduct a citation analysis of the most cited articles related to calcaneus fractures to highlight the most historically influential articles, as well as the more recent breakthrough articles that are leading change within the field. Methods: A literature search was performed via Scopus on September 20, 2021 using the terms "(calcaneus OR calcaneal OR hindfoot) AND (fracture OR injury)" to search "article title, abstract, and keywords" of all primary and review articles. Search results were rigorously reviewed to ensure appropriateness for this study. The 50 highest total cited included articles were analyzed. Title, authors, journal, country of origin, institution, year of publication, citation variables (total citation count, total citation density, citation count from the last 5 years, and 5-year citation density), and level of evidence were collected for each article. One-way analysis of variance with post hoc testing was used to identify differences in citation variables and level of evidence. Pearson correlation was used to directly compare different citation variables. Results: The total citation count average was 178±33, with a total citation density average of 9±2. The year of publication for the 50 articles ranged from 1948 to 2014, with a median year of 1999. Roy W. Sanders was the most productive author in the field, authoring 6 articles and lead authoring 3. The most frequent level of evidence was IV with 19 articles. There was a strong correlation between total citation density and 5-year citation density. The article level of evidence showed no impact on the included measures of an article's influence. Conclusion: This study successfully analyzes and presents the characteristics among the highest cited articles related to calcaneus fractures. The provided characterization of influential works and authors highlights trends, impactful findings, and future areas of focus within calcaneus fracture literature.Level of Evidence: Review Article.

30-Day outcomes analysis of surgical management of radial head fractures comparing radial head arthroplasty to open reduction internal fixation.

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

Algorithm Improves Acetabular Fracture Radiograph Interpretation Among Inexperienced Practitioners.

Acetabular fractures are often first evaluated in the emergency department, where physicians with little experience reading pelvic radiographs may be required to make an accurate diagnosis and early management decisions. In this study, medical students classified radiographs of 20 acetabular fractures and repeated the exercise three weeks later with the aid of a previously described algorithm; half the students were given a lesson prior to using the algorithm. The pre-algorithm accuracy was 4/20 and the post-algorithm accuracy was 8.3/20 (p<0.01). The lesson provided no difference (p=0.5). This algorithm is therefore a useful reference to help classify and triage acetabular fractures.

Determining the incidence and risk factors for short-term complications following distal biceps tendon repair.

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

Revision ACL reconstruction has higher incidence of 30-day hospital readmission, reoperation, and surgical complications relative to primary procedures.

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

Short-Term Outcomes After Total Shoulder Arthroplasty in Octogenarians: A Matched Analysis.

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

Epidemiology and risk factors for loss to follow-up following operatively treated femur ballistic fractures.

INTRODUCTION: Evidence regarding recommendations for treatment of ballistic fractures remains limited. This paucity of literature has largely been attributed to gunshot wound victims being a difficult population to study secondary to loss to follow-up. The purpose of this study was to examine the epidemiology of operatively treated ballistic femur fractures at our institution, the frequency of outpatient follow-up and risk factors for loss to follow-up. METHODS: Inpatient consults from 2013-2018 were queried for femoral gunshot wounds treated operatively. Cases without internal or external fixation were excluded from the study. Postoperative visits where a patient was hospitalized or had expired were excluded from the analysis. Demographic information, length of hospital stay, and operative characteristics were compared for different fixation methods and examined as risk factors for loss to follow-up. RESULTS: A total of 194 patients met inclusion criteria. The average age was 27 years old and 94% of the patients were male. Patient's stayed a median of 5 days post-operatively with patients treated with external fixation staying longer than internal fixation (14 days vs 5 days p=0.01). 9.3% of ballistic fractures had a concomitant vascular injury necessitating repair. 70.4% of patients attended their 2-week postoperative visit, 55.7% of patients attended their 6 week follow-up visit and 31.3% attended their 3 month follow-up visit. Risk factors for loss to follow-up at 3 month visit included younger age (p=0.028), decreased hospital length of stay (p=0.025) and intramedullary fixation (p=0.00015). DISCUSSION AND CONCLUSION: This study reinforces the difficulty of studying ballistic fractures secondary to loss to follow-up. Younger age, shorter hospital stays and intramedullary fixation increased the risk for loss to follow-up at 3 months.
