RESUMO
INTRODUCTION: The opioid epidemic in the United States has contributed to a notable economic burden and increased mortality. Total shoulder arthroplasty (TSA) has become more prevalent, and opioids are commonly used for postoperative pain management. Prolonged opioid use has been associated with adverse outcomes, but the role of surgeons in this context remains unclear. This study aims to investigate the incidence and risk factors of prolonged opioid utilization after primary TSA. METHODS: After obtaining institutional review board approval, a retrospective review of 4,488 primary total shoulder arthroplasties from 2014 to 2022 at a single academic institution was conducted. Patients were stratified by preoperative and postoperative opioid use, and demographic, clinical, and prescription data were collected. Prescriptions filled beyond 30 days after the index operation were considered prolonged use. Multivariate analysis was conducted to determine the independent risk factors associated with prolonged opioid utilization. RESULTS: Among 4,488 patients undergoing primary TSA, 22% of patients developed prolonged opioid use with 70% of prolonged users being opioid-exposed preoperatively. Independent risk factors of prolonged use include patient age younger than 65 years (Odds Ratio (OR) 1.02, P < 0.001), female sex (OR 1.41, P < 0.001), race other than Caucasian (OR 1.36, P = 0.003), undergoing reverse TSA (OR 1.28, P = 0.010), residing in an urban community (OR 1.33, P = 0.039), preoperative opioid utilization (OR 6.41, P < 0.001), preoperative benzodiazepine utilization (OR 1.93, P < 0.001), and increased postoperative day 1-30 milligram morphine equivalent (OR 1.003, P < 0.001). DISCUSSION: Nearly 22% of patients experienced prolonged opioid use, with preoperative opioid exposure being the most notable risk factor in addition to postoperative prescribing patterns and benzodiazepine utilization. Surgeons play a crucial role in opioid management, and understanding the risk factors can help optimize benefits while minimizing the associated risks of prolonged opioid use. Additional research is needed to establish standardized definitions and strategies for safe opioid use in orthopaedic surgery.
RESUMO
Background: Implant removal due to infection is one of the major causes failure following open reduction and internal fixation (ORIF). The aim of this study was to determine trends and predictors of infection-related implant removal following ORIF of extremities using a nationally representative database. Methods: Nationwide Inpatient Sample data from 2006 to 2017 was used to identify cases of ORIF following upper and lower extremity fractures, as well as cases that underwent infection-related implant removal following ORIF. Multivariate analysis was performed to identify independent predictors of infection-related implant removal, controlling for patient demographics and comorbidities, hospital characteristics, site of fracture, and year. Results: For all ORIF procedures, the highest rate of implant removal due to infection was the phalanges/hand (5.61%), phalanges/foot (5.08%), and the radius/ulna (4.85%). Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Tarsal/metatarsal fractures (odds ratio (OR)=1.45, 95% confidence interval (CI): 1.02-2.05), and tibial fractures (OR=1.82, 95% CI: 1.45-2.28) were identified as independent predictors of infection-related implant removal. Male gender (OR=1.67, 95% CI: 1.49-1.87), Obesity (OR=1.85, 95% CI: 1.34-2.54), diabetes mellitus with chronic complications (OR=1.69, 95% CI: 1.13-2.54, P<0.05), deficiency anemia (OR=1.59, 95% CI: 1.14-2.22) were patient factors that were associated with increased infection-related removals. Removal of implant due to infection had a higher total charge associated with the episode of care (mean: $166,041) than non-infection related implant removal (mean: $133,110). Conclusion: Implant removal rates due to infection decreased in all fractures except radial/ulnar fractures. Diabetes, liver disease, and rheumatoid arthritis were important predictors of infection-related implant removal. The study identified some risk factors for implant related infection following ORIF, such as diabetes, obesity, and anemia, that should be studied further to implement strategies to reduce rate of infection following ORIF.
RESUMO
Tumor size and growth are important parameters when evaluating bone and soft tissue neoplasms. There are no reports comparing the intra- and interobserver reliability among physicians in their evaluation of musculoskeletal (MSK) tumor imaging. This study investigates the accuracy and precision of measurements made by orthopedic and radiology physicians in different stages of training. Blinded magnetic resonance imaging (MRI) scans from six patients, three soft tissue, and three bone tumors were selected: each case included an "old" and "new" scan that was performed at least 3 months apart. Fourteen participants were selected, representing varying levels of education and experience, including two of each of the following: medical students, orthopedic and radiology residents, oncology and nononcologic orthopedic attendings, and MSK and non-MSK radiology attendings. Participants compared the old and new studies, recording tumor size in the transverse, cranial-caudal, and anterior-posterior dimensions, and determined if the tumor was stable or unstable. The MRI's official report served as the "gold standard." Average intraobserver variability (|Trial 1 - Trial 2|/[(Trial 1 + Trial 2)/2])) in size measurements was 11.08% (0.00%-68.62%). The lowest variability was recorded by the MSK radiologist 1 (6.16%), and the greatest variability by Orthopedic Surgery Resident 1 (16.70%). Participants correctly determined stability 82% of the time (71%-100%). Only MSK radiologists correctly determined stability in over 90% of cases. There is considerable variability and inaccuracy in MRI-based measurements of MSK tumors. These findings motivate opportunities for improving MSK imaging education of radiology and orthopedic residents. Physicians ordering MRI scans should evaluate them themselves, instead of relying on the radiology report alone, to inform clinical decision-making.

CASE: Medial collateral ligament (MCL) injuries after total knee arthroplasty (TKA) are a rare occurrence. Traditional treatment options include repair and revision to a constrained prosthesis. We present a case of an 80-year-old man who opted for MCL reconstruction in the setting of previous TKA due to late MCL injury from a skiing accident. The presentation, operative techniques, and outcomes of this treatment option are presented. CONCLUSIONS: MCL reconstruction in the setting of TKA can lead to a successful and satisfactory outcome without the need for revision TKA.

In this paper we present the findings of a literature review covering articles published in the last three decades describing the application of telemedicine in orthopaedics. A review of the PubMed Central and Medline provided 75 articles studying the role of telemedicine, the majority directly examining the application of telemedicine in orthopaedic patients. We report the summarized findings of these studies, the financial and HIPAA considerations of using telemedicine, and provide an example of our single urban level-1 trauma center's strategy for incorporating telemedicine into the clinical practice of orthopaedic surgeons during the COVID-19 pandemic.
RESUMO
As a part of the American healthcare system's response to the Coronavirus Disease 2019 (COVID-19) global pandemic, the Association of American Medical Colleges recommended that medical schools temporarily remove students from clinical settings and transition to an entirely online learning environment. This posed an unprecedented challenge to students in the clinical years of their medical education. To address this unexpected shift, we modified an in-person workshop to teach orthopaedic trauma basics to 5-week virtual course for third year medical students from several schools in New Jersey and Pennsylvania. We focused on moving students toward the Level-1 milestones for basic fracture care with a combination of weekly lectures and virtual interactive small group sessions, all conducted via WebEx and proctored by an orthopaedic attending or resident. The course was well received by students. Participation in the course was completely voluntary and did not count for credit at any institution. The course was valuable to students because the students who registered chose to fully complete the 5-week course and no student missed more than one small group session. On a postcourse survey, 100% of students said they would be highly likely to recommend the course to a future student, and the average rating for educational value of the course was 4.98 of 5. Given the current limitations in clinical education because of the COVID-19 pandemic, our course provides a reasonable alternative to clinical experience and prepares students with the knowledge and many of the skills that are required to succeed as orthopaedic interns. Furthermore, the success of our course this year suggests that similar programing may be a useful adjunct to clinical experiences even when it is safe to return to more traditional medical school scheduling.
RESUMO
INTRODUCTION: Chondroblastomas are benign, locally aggressive bone tumors that occur in the epiphysis of young patients, requiring surgical excision. The anatomic locations of these lesions pose technical challenges to the surgeon; their proximity to the articular surface and the physis make surgical approach and visualization difficult. This case series describes the use of intramedullary arthroscopic assistance during excisional curettage of three distal femoral chondroblastomas. CASE REPORT: Three patients with distal femoral chondroblastomas underwent excisional curettage with intraosseous "dry" arthroscopic assistance. We describe a two-tunnel technique, using medial and lateral windows so the arthroscope and working instruments could be within the lesion simultaneously; as well as two variations of a single-tunnel technique. CONCLUSION: Achieving adequate ex---posure and visualization, while protecting the articular surface and physis, during excision of chondroblastomas, is essential for avoiding local recurrence and complications. "Dry" arthroscopic assistance provides the surgeon with an enhanced view of the tumor and tumor cavity, minimizes invasiveness, and has the potential to reduce complications without compromising the completeness of the excision.
RESUMO
CASE: A 24-year-old woman with chondrosarcoma of the superior pubic ramus underwent a Type III pelvic resection through an ilioinguinal approach, modified with anterior superior iliac spine (ASIS) osteotomy. The osteotomy mobilized the ASIS and sartorious distally, exposing the anterior wall and superior ramus. A custom cutting guide was placed on the anterior acetabular wall for en bloc superior ramus resection with hip-sparing osteotomy and negative margins. CONCLUSION: ASIS osteotomy for sartorius mobilization improves visualization of the anterior column of the acetabulum and heals more reliably than sartorius tenotomy, therefore should be considered during tumor resection involving the anterior column, superior ramus, or acetabular wall.

Endoprosthetic reconstructions of the hip and knee are currently reimbursed as primary hip and knee arthroplasty according to Current Procedural Terminology (CPT) coding guidelines. The purpose of this study was to compare hospital resources consumed by patients undergoing endoprosthetic reconstruction with those consumed by patients undergoing primary arthroplasty. The authors' hypothesis was that the former group carries more comorbidities, experiences longer length of stay (LOS), and has greater resource consumption. A retrospective review was performed of 61 patients undergoing endoprosthetic reconstruction and 745 patients undergoing primary hip or knee arthroplasty between 2015 and 2018 at a single institution. Demographic, clinical, and financial data were compared. The Charlson Comorbidity Index (CCI) was used to measure patients' health status and identify comorbidities associated with prolonged LOS through linear regression analysis. Patients who underwent endoprosthetic reconstruction had a greater than 3.5 times average LOS compared with primary arthroplasty patients: 10.81 days vs 2.94 days (P<.01). They demonstrated a higher mean CCI, higher rates of malignancy and pulmonary disease, and a wider age range. Their mean cost of care totaled $73,730.29, compared with $24,940.84 imposed by primary arthroplasty patients (P<.01). Significant predictors of LOS were malignancy status (metastatic or localized) and age younger than 50 years, with increased LOS being associated with increased cost. Patients undergoing endoprosthetic reconstruction of the hip and knee represent a fundamentally different patient population than primary arthroplasty patients based on comorbidities, variability in health status, and surgical indications. They have higher comorbidity scores and longer hospitalizations and consume more financial resources than primary arthroplasty patients. [Orthopedics. 2021;44(1):e73-e79.].

BACKGROUND: Duodenal adenocarcinoma treatment consists of either simple or radical surgical resection. Existing evidence suggests similar survival outcomes between the two but is limited by small numbers and single-institution analysis. We aim to compare survival after partial versus radical resection for duodenal adenocarcinoma using the National Cancer Database (NCDB). METHODS: Using NCDB results from 2004 to 2014, we compared patients with duodenal adenocarcinoma undergoing partial resection (n = 1247) and radical resection (n = 1240) by age, sex, facility type, facility location, cancer stage, cancer grade, lymph node sampling, node status, tumor size, margin status, neoadjuvant therapy, and adjuvant therapy using chi-square analysis. Survival was compared using propensity matching. RESULTS: Patients undergoing partial resection had overall earlier cancer stage, more favorable tumor grade, and were less likely to undergo lymph node sampling and neoadjuvant therapy. When overall survival was compared between the 2 propensity-matched groups, the median survival was 46.7 months after partial resection and 43.2 months after radical resection (P = .329), and overall survival was similar between the 2 groups (P = .894). The use of adjuvant therapy demonstrated improved survival over either surgery alone (P < .0001, P = .0037). CONCLUSION: Partial resection did not demonstrate worse survival outcomes than radical resection for duodenal adenocarcinoma. The use of adjuvant therapy in addition to surgery demonstrated improved survival regardless of surgery type and played a larger role in survival than the type of surgery. Our findings provide evidence to support the continued use of both partial and radical surgical resections to treat duodenal malignancy.

Numerous cell lines for human alveolar rhabdomyosarcoma (ARMS) have been developed and are widely used to study biological processes of this myogenic cancer. The present study investigated the resemblance of commonly used ARMS cell lines to primary tumors in regards to gene expression. RNA-sequencing data was retrieved from published datasets for 4 commonly used ARMS cell lines and 35 ARMS primary tumors. The genes with most variable expression across primary tumors were used to calculate rank-based Spearman's correlation. The observed median correlations ranged from 0.36 to 0.61. RH-41 showed the highest median correlation while KYM-1 was the least correlated cell line. A significant number of genes dysregulated between tumors and non-tumors also exhibited similar expression patterns between tumors and cell lines, including The findings suggest that ARMS cell lines exhibit changes in gene expression compared to primary tumors and may not be completely representative of the disease process.

Introduction Patellofemoral pain syndrome (PFPS) is one of the leading causes of anterior knee pain treated by orthopedists and physical therapists. This syndrome predominantly affects young, active individuals, and remains a challenging syndrome to manage due to the lack of quantitative diagnostic criteria to monitor during treatment. The etiology of this syndrome is believed to be multifactorial, with the gait and movement patterns of a patient potentially contributing to pain due to increased stress on the knee. In this study, we investigated the gait of participants with PFPS using the GaitRite system (CIR Systems Inc., Clifton, NJ) before and after the application of Kinesio Tape in order to assess the impact of Kinesio Tape on cadence, stance time, and pain. Methods A convenience sample of 10 participants were recruited for this study, with five participants without PFPS serving as controls, and five with PFPS in the Kinesio Tape group. Participants in the Kinesio Tape groups served as their own internal control, ambulating both before and after taping. All participants ambulated across the GaitRite carpet three times and completed a visual analogue scale pain score for each trip. Results The results of our study found there to be no significant difference in the cadence for gait between the participants without PFPS and participants with PFPS (105.2 seconds vs. 105.1 seconds, p = 0.272), or in the stance time between the control and PFPS group (1.43 seconds vs. 1.44, p = 0.907). Similarly, no significant difference was found in participants with PFPS before and after Kinesio Taping in the cadence and stance times (105.1 seconds vs. 107.4 seconds, p =0.288, and 1.44 vs. 1.40, p = 0.272). There was a significant difference in pain in PFPS participants before and after taping, with a 112.5% reduction in pain reported after taping (3.4 vs. 1.6, p < 0.05). Discussion and conclusion This study is one of the first studies to utilize the GaitRite system in order to analyze the impact of Kinesio Tape on gait in participants with PFPS. While our study failed to demonstrate a significant difference in the gait of participants with PFPS in comparison to those without PFPS, we did demonstrate a significant reduction in pain after the application of Kinesio Tape. These results suggest other variables addressed by the Kinesio Tape may be causing the pain associated with PFPS.
RESUMO
Pulmonary hypertension (PH) can occur in patients with undiagnosed congenital heart disease, like atrial septal defects (ASDs), causing chronic left-to-right shunting. This may ultimately result in Eisenmenger physiology or syndrome (ES), a reversal of left-to-right shunting, resulting in a right-to-left shunt, thereby causing deoxygenated blood to enter systemic circulation as it bypasses the lungs. Development of PH due to an ASD is uncommon, and the occurrence of ES is <1% as most ASDs are corrected early in life. We present a 28-year-old female presenting with new-onset dyspnea found to have an undiagnosed ASD with ES. A 28-year-old female without past medical history presented to the emergency department after a chest x-ray performed by her primary care physician (PCP) showed dilation of the pulmonary artery concerning PH. The patient reported a three-month history of progressively worsening intermittent palpitations and dyspnea, now unable to walk more than one block without becoming dyspneic. Further imaging studies revealed a 1.4 centimeters (cm) secundum ASD, 4.4 cm dilatation of the PA, a mean pulmonary artery pressure (PAPm) of 132 millimeters (mm) mercury (Hg), and Eisenmenger physiology. She was placed on pulmonary vasodilators and iron supplementation to address an underlying iron-deficiency anemia. The patient is stable on her current regimen and is undergoing evaluation for possible heart-lung transplantation at an outside hospital. Dyspnea is one of the top 10 most common indications for emergency room visits annually. The differential diagnosis for dyspnea is vast, with ES, affecting only 0.8 in 1 million, far down on the list of possibilities, thus requiring high clinical suspicion to prompt further evaluation. Ultimately, the condition is preventable with early identification of underlying structural abnormalities for which definitive treatment options exist and are readily available, dramatically improving the prognosis if implemented before ES develops.
RESUMO
BACKGROUND: Anal SCC is a rare disease mainly treated with chemoradiation. Abdominoperineal resection (APR), once the mainstay of treatment for anal cancer, now serves a role as salvage therapy for persistent or recurrent disease after chemoradiation. In addition, clinically positive nodes are currently treated by extending the radiation field to the groin. The role of inguinal lymph node dissection in recurrent or persistent anal SCC is unclear. The aim of the study is to determine the role of inguinal lymph node dissection in the management of inguinal lymph node metastasis for anal squamous cell carcinoma (SCC). METHODS: Retrospective analysis of patients with anal SCC in the National Cancer Database with positive inguinal nodes undergoing salvage APR between 2004 and 2014 was performed. A comparison of overall survival between patients who underwent APR with lymph node dissection versus APR only was analyzed using Kaplan-Meier plot. RESULTS: A total of 3424 patients underwent salvage APR, with 274 (8%) having clinically positive nodes. Within the subgroup that had clinically positive nodes, 195 (71%) underwent APR, whereas 79 (29%) underwent both APR and node dissection. Kaplan-Meier analysis demonstrates no difference in overall survival in the two groups (P = 0.99). Five-year survival for both groups was similar (36% versus 42%; P = 0.987). No significant difference was found when adjusted for age, gender, and Tumor Node Metastasis staging. CONCLUSIONS: Inguinal lymph node dissection does not appear to improve overall survival in patients with advanced-stage anal cancer requiring salvage APR. Proper patient selection for node dissection is essential to spare patients from additional morbid procedures.
