Increased Duration and Frequency of Lateral C-Arm Draping Does Not Increase Contamination Rates.

This study sought to quantify the rate of culture-positive drape contamination with varying degrees of drape manipulation for intra-operative fluoroscopic imaging. In this prospective cohort study, 30 patients with operatively closed lower extremity fractures were evaluated. The clip-drape technique was employed to cover the emitter. Swab samples were collected for bacterial growth. A t-test was applied for statistical comparison. Three of 30 cases (10% of operations) showed evidence of contamination. There was no statistically significant difference between duration of drape use or the amount of drape manipulations. None of the 30 patients in this study developed surgical site infection 90-days post-surgery. The clip drape technique for lateral fluoroscopy appears to be effective in maintaining surgical field sterility. Moreover, the number of drape manipulations and length of time the drape was in use was not related to drape contamination. Level of Evidence: Therapeutic Level II.

Racial and Sex Disparities in Resident Attrition in Orthopaedic Surgery.

Studies have suggested that female individuals and individuals from backgrounds under-represented in medicine (URiM) are at increased risk of attrition during residency. This likely exacerbates the lack of diversity in our field. The aims of this study were to (1) characterize demographic composition in orthopaedic residency from 2001 to 2018 and (2) determine the race/ethnicity and identify any disparities. Methods: Demographic and attrition data from 2001 to 2018 were obtained from the Association of American Medical Colleges. Attrition data comprised the following categories: withdrawals, dismissals, and transfers to another specialty. Analysis compared demographic composition and determined attrition rates with subgroup analysis by race/ethnicity and sex. Results: From 2001 to 2018, female orthopaedic residents increased from 8.77% to 15.54% and URiM residents from 9.49% to 11.32%. The overall and unintended attrition rates in orthopaedic surgery were 3.20% and 1.15%, respectively. Among female residents, the overall and unintended attrition rates were 5.96% and 2.09% compared with 2.79% and 1.01%, respectively, in male residents. URiM residents had overall and unintended attrition rates of 6.16% and 3.11% compared with 2.71% and 0.83%, respectively, for their White counterparts. Black/African American residents had an attrition rate of nearly 10%. Female residents averaged 12.9% of all residents but 24% of those leaving orthopaedics. URiM residents were 10.14% of all residents but 19.51% of those experiencing attrition. In logistic regression models, female residents had a relative risk (RR) of 2.20 (p < 0.001) for experiencing all-cause attrition and 2.09 (p < 0.001) for unintended attrition compared with male residents. Compared with their White male counterparts, URiM residents had a RR for overall and unintended attrition of 2.36 and 3.84 (p < 0.001), respectively; Black/African American residents had a RR for the same of 3.80 and 7.20 (p < 0.001), respectively. Conclusion: Although female resident percentage has increased, orthopaedics continues to train fewer female surgeons than all other fields. Female and URiM residents in orthopaedic surgery are disproportionately affected by attrition. While recruitment has been the primary focus of diversity, equity, and inclusion efforts, this study suggests that resident retention through appropriately supporting residents during training is equally critical.

Racial and Sex Disparities in Resident Attrition Among Surgical Subspecialties.

Importance: Racial and sex disparities are prevalent in surgical trainees. Although retrospective studies on resident attrition have been conducted for individual specialties, this study analyzes racial and sex differences in resident attrition among all surgical subspecialties over an 18-year period. Objective: To evaluate the racial and sex differences in resident attrition among surgical specialties over an 18-year period. Design, Setting, and Participants: This was a large, cross-sectional, database study that analyzed program-reported resident censuses (program information, resident demographics, and attrition status) obtained by the Association of American Medical Colleges from 2001 to 2018 for trainees in surgical residency programs. Data were analyzed from March 20, 2021, to June 8, 2022. Main Outcomes and Measures: Demographic trends (including race and ethnicity and sex) for all surgical subspecialty training programs over an 18-year period. Resident attrition includes all-cause withdrawals, dismissals, and transfers to another specialty. Unintended attrition encompasses all withdrawals, dismissals, and transfers except for changing career plans. Results: This study included 407 461 program-reported resident years collected from 112 205 individual surgical residents (67 351 male individuals [60.0%]). The mean percentage of female trainees was 40.0% (44 835) and increased over the study period. Sex disparity remained greatest in orthopedic surgery. Residents who were underrepresented in medicine (URiM) comprised 14.9% (16 695) of all surgical trainees but demonstrated a 2.1% decrease over the study period. Overall attrition rate among all specialties was 6.9% (7759), with an unintended attrition rate of 2.3% (2556). Female residents had a significantly higher relative risk (RR) of attrition (RR, 1.16; 95% CI, 1.11-1.22; P < .001) and unintended attrition (RR, 1.17; 95% CI, 1.08-1.26; P < .001) compared with their male counterparts. URiM residents were at significantly higher RR for attrition (RR, 1.40; 95% CI, 1.32-1.48; P < .001) and unintended attrition (RR, 1.92; 95% CI, 1.75-2.11; P < .001) compared with non-URiM residents. The highest attrition (10.6% [746 of 7043]) and unintended attrition (5.2% [367 of 7043]) rates were in Black/African American residents. The lowest attrition and unintended attrition rates were seen in White residents at 6.2% (4300 of 69 323) and 1.8% (1234 of 69 323), respectively. Black/African American residents were at disproportionate risk for attrition (RR, 1.66; 95% CI, 1.53-1.80; P < .001) and unintended attrition (RR, 2.59; 95% CI, 2.31-2.90; P < .001) compared with all other residents. Orthopedic surgery had the highest attrition (RR, 3.80; 95% CI, 2.84-5.09; P < .001) and unintended attrition (RR, 7.20; 95% CI, 4.84-10.71; P < .001) for Black/African American residents. Conclusions and Relevance: Results of this cross-sectional study suggest that the percentage of female residents in surgical specialties has improved over the last 18 years, and the percentage of URiM residents has remained relatively unchanged. Risk for attrition and unintended attrition was significantly elevated for female and URiM residents, specifically Black/African Americans. These results highlight current racial and sex disparities in resident attrition and demonstrate the importance of developing strategies to recruit, retain, and support residents.

COVID-19 Shelter-In-Place Orders Associated With Delayed Presentation and Deep Venous Thrombosis in Geriatric Hip Fractures.

Geriatric hip fractures benefit from timely surgery. At the onset of the corona-virus disease 2019 (COVID-19) pandemic, shelter-in-place (SIP) orders were mandated in high-risk cities. The authors hypothesized that geriatric patients with hip fractures were more likely to present to the hospital greater than 24 hours after injury during SIP orders. They retrospectively reviewed patients 65 years or older who presented with hip fractures between March 20, 2020, and May 24, 2020 (SIP group), and between March 20, 2019, and May 24, 2019 (historical group). Primary outcomes were incidence of presentation greater than 24 hours after injury and mean number of days between injury and presentation. Secondary outcomes were incidence of preoperative deep venous thrombosis (DVT) and 30- and 90-day mortality rates. Thirty-three patients comprised the SIP group, and 50 patients comprised the historical group. There were no significant differences in their demographics or medical comorbidities. The SIP group was more likely to present greater than 24 hours after injury (P=.05) and presented a greater number of days after injury (P=.02). There was a significant difference in the incidence of preoperative DVT (P=.03). There were no significant differences in 30- and 90-day mortality rates. Geriatric patients who sustained hip fractures during SIP restrictions for COVID-19 were more likely to present greater than 24 hours after injury, have a greater number of days between injury and presentation, and be diagnosed with a preoperative DVT.

Low Adherence to Recommended Guidelines for Open Fracture Antibiotic Prophylaxis.

BACKGROUND: Prompt administration of antibiotics is a critical component of open fracture treatment. Traditional antibiotic recommendations have been a first-generation cephalosporin for Gustilo Type-I and Type-II open fractures, with the addition of an aminoglycoside for Type-III fractures and penicillin for soil contamination. However, concerns over changing bacterial patterns and the side effects of aminoglycosides have led to interest in other regimens. The purpose of the present study was to describe the adherence to current prophylactic antibiotic guidelines. METHODS: We evaluated the antibiotic-prescribing practices of 24 centers in the U.S. and Canada that were participating in 2 randomized controlled trials of skin-preparation solutions for open fractures. A total of 1,234 patients were evaluated. RESULTS: All patients received antibiotics on the day of admission. The most commonly prescribed antibiotic regimen was cefazolin monotherapy (53.6%). Among patients with Type-I and Type-II fractures, there was 61.1% compliance with cefazolin monotherapy. In contrast, only 17.2% of patients with Type-III fractures received the recommended cefazolin and aminoglycoside therapy, with an additional 6.7% receiving piperacillin/tazobactam. CONCLUSIONS: There is moderate adherence to the traditional antibiotic treatment guidelines for Gustilo Type-I and Type-II fractures and low adherence for Type-III fractures. Given the divergence between current practice patterns and prior recommendations, high-quality studies are needed to determine the most appropriate prophylactic protocol.

Fascia Iliaca Regional Anesthesia in Hip Fracture Patients Revisited: Which Fractures and Surgical Procedures Benefit Most?

OBJECTIVES: Perioperative fascia iliaca regional anesthesia (FIRA) decreases pain in hip fracture patients. The purpose of this study is to determine which hip fracture types and surgical procedures benefit most. DESIGN: Prospective observational study compared with a retrospective historical control. PATIENTS/PARTICIPANTS: Patients older than 60 years who received perioperative FIRA were compared with a historical cohort not receiving FIRA. SETTING: This study was conducted at a Level 1 trauma center. MAIN OUTCOME MEASUREMENTS: The primary outcome was morphine milliequivalents (MME) consumed during the index hospitalization. Fracture pattern-specific preoperative and postoperative MME consumption and surgical procedure-specific postoperative MME consumption was compared between the FIRA and non-FIRA groups. RESULTS: A total of 949 patients were included in this study, with 194 (20.4%) patients in the prospective protocol group. There were no baseline differences between cohorts. Preoperatively, only femoral neck fracture patients receiving FIRA used fewer MME (P < 0.001). Postoperatively, femoral neck fracture patients receiving FIRA used fewer MME on postoperative day (POD) 1 (P = 0.027) and intertrochanteric fracture patients used fewer MME on POD1 and POD2 (P = 0.013; P = 0.002). Cephalomedullary nail patients receiving FIRA used fewer MME on POD1 and POD2 (P = 0.004; P = 0.003). Hip arthroplasty patients receiving FIRA used fewer MME on POD1 (P = 0.037). Percutaneous pinning and sliding hip screw patients had no significant MME reduction from FIRA. CONCLUSIONS: Preoperatively, patients with femoral neck fractures benefit most from FIRA. Postoperatively, both patients with femoral neck fractures and intertrochanteric fractures benefit from FIRA. Patients undergoing cephalomedullary nail fixation or hip arthroplasty benefit most from FIRA postoperatively. LEVEL OF EVIDENCE: Therapeutic Level III.

How Are Orthopaedic Surgery Residencies Responding to the COVID-19 Pandemic? An Assessment of Resident Experiences in Cities of Major Virus Outbreak.

BACKGROUND: In response to COVID-19, American medical centers have enacted elective case restrictions, markedly affecting the training of orthopaedic residents. Residencies must develop new strategies to provide patient care while ensuring the health and continued education of trainees. We aimed to describe the evolving impact of COVID-19 on orthopaedic surgery residents. METHODS: We surveyed five Accreditation Council for Graduate Medical Education-accredited orthopaedic residency programs within cities highly affected by the COVID-19 pandemic about clinical and curricular changes. An online questionnaire surveyed individual resident experiences related to COVID-19. RESULTS: One hundred twenty-one resident survey responses were collected. Sixty-five percent of the respondents have cared for a COVID-19-positive patient. One in three reported being unable to obtain institutionally recommended personal protective equipment during routine clinical work. All programs have discontinued elective orthopaedic cases and restructured resident rotations. Most have shifted schedules to periods of active clinical duty followed by periods of remote work and self-isolation. Didactic education has continued via videoconferencing. DISCUSSION: COVID-19 has caused unprecedented changes to orthopaedic training; however, residents remain on the front lines of inpatient care. Exposures to COVID-19 are prevalent and residents have fallen ill. Programs currently use a variety of strategies to provide essential orthopaedic care. We recommend continued prioritization of resident safety and necessary training accommodations.

Metabolic factors and post-traumatic arthritis may influence the increased rate of surgical site infection in patients with human immunodeficiency virus following total hip arthroplasty.

BACKGROUND: The impact of CD4+ T-cell count and highly active antiretroviral therapy (HAART) on the rate of surgical site infection (SSI) in patients with human immunodeficiency virus (HIV) undergoing total hip arthroplasty is still unclear. The goals of this study were to assess the rate of perioperative infection at a large tertiary care referral center and to identify risk factors in HIV+ patients undergoing total hip arthroplasty (THA). METHODS: This study was a prospective, observational study at a single medical center from 2000-2017. Patients who were HIV+ and underwent THA were followed from the preoperative assessment period, through surgery and for a 2-year follow-up period. RESULTS: Sixteen of 144 HIV+ patients (11%) undergoing THA developed perioperative surgical site infections. Fourteen patients (10%) required revision THA within a range of 12 to 97 days after the initial surgery. The patients' mean age was 49.6 ± 4.5 years, and the most common diagnosis prompting THA was osteonecrosis (96%). Patients who developed SSI had a lower waist-hip ratio (0.86 vs. 0.93, p = 0.047), lower high density lipoprotein cholesterol (45.8 vs. 52.5, p = 0.015) and were more likely to have post-traumatic arthritis (12.5% vs. 0%, p = 0.008). Logistic regression analysis demonstrated that current alcohol use and higher waist-hip ratio were significant protectors against infection (p < 0.05). No other demographic, medical, immunologic parameters, or specific HAART regimens were associated with perioperative infection. CONCLUSIONS: Immunologic status as measured by CD4+ cell count, HIV viral load, and medical therapy do not appear to influence the development of SSI in HIV+ patients undergoing THA. Metabolic factors and post-traumatic arthritis may influence the increased rate of infection in HIV+ patients following THA.

The Drape Tower: A "Hands-Free" Draping Technique for Intraoperative Lateral Fluoroscopy Views.

SUMMARY: Maintaining surgical field sterility during fracture surgery is critical for reducing the likelihood of postoperative infection. Lateral fluoroscopic views are frequently obtained by rotating the emitter under the bed and up immediately adjacent to the sterile field on the side of the injured limb. Contamination can be prevented by sterilely covering the emitter with each rotation from the upright to the lateral positions. Here, we describe a novel draping setup, which maintains fluoroscopic coverage in a "hands-free" manner. The technique uses widely available materials and allows the surgeon to proceed with surgery without the need for additional hands to manage the drape.

Pain Management with Early Regional Anesthesia in Geriatric Hip Fracture Patients.

BACKGROUND: Geriatric hip fracture patients are susceptible to the adverse effects of opioid-induced analgesia. Fascia iliaca blocks (FIBs) have emerged as an analgesic technique for this population. There are limited data on a preoperative FIB's effect on perioperative opioid intake. We hypothesized that preoperative FIB would reduce perioperative opioid consumption, measured in morphine milliequivalents (MMEs). DESIGN: This is a prospective observational study. SETTING: A level 1 trauma center in California. PARTICIPANTS: From March 2017 to December 2017, patients 65 years and older presenting with a hip fracture received a preoperative FIB and were prospectively observed. This cohort was compared with a historical control. INTERVENTION: All prospectively enrolled patients were given FIBs. For a single-shot FIB, a 30- to 40-mL bolus of 0.25% bupivacaine with 1:200,000 epinephrine was injected. For a continuous FIB, a bolus of 10 to 20 mL of 0.2% bupivacaine was injected, followed by a continuous infusion of 0.2% bupivacaine at 6 mL/h ending on the morning of postoperative Day 1. RESULTS: A total of 725 patients were included in this study, with 92 in the prospectively collected cohort. The mean age of this cohort was 84.2 (standard deviation = 8.4) years, and 69.2% were female. Patients who received a preoperative FIB consumed less MME preoperatively, 18.0 (interquartile range = 6.0-44.5) versus 29.5 (interquartile range = 6.0-56.5) (P = .007), with no change in pain scores. No differences were found in postoperative opioid consumption between groups. There was no difference in MME or pain score in patients with dementia. Subgroup analysis based on fracture pattern (femoral neck and intertrochanteric) demonstrated a significant decrease in preoperative MME consumption in femoral neck fractures only, 12.0 (interquartile range = 5.0-24.0) versus 29.0 (interquartile range = 12.0-59.0) (P < .001). CONCLUSION: FIBs reduce preoperative opioid intake and have low rates of opioid-related adverse events in geriatric hip fracture patients. LEVEL OF EVIDENCE: The level of evidence was II.

A Comparison in Outcomes of Preoperative Single-shot versus Continuous Catheter Fascia Iliaca Regional Anesthesia in Geriatric Hip Fracture Patients.

BACKGROUND: Fascia iliaca nerve blocks relieve pain in geriatric hip fracture patients and can be administered via a single-shot or continuous catheter. We compared perioperative opioid consumption and pain scores between these two blocks. METHODS: We performed a prospective, observational cohort study, including geriatric hip fracture patients who received a preoperative block. We compared morphine milligram equivalent (MME) consumption and visual analog scale (VAS) pain scores between single-shot and continuous fascia iliaca blocks at multiple time points: preoperative and on postoperative (POD) day 0, 1, and 2. We compared the change in preoperative total and hourly opioid consumption before and after block placement within and between groups. Secondary outcomes included opioid related adverse events, length of stay, and readmission rates. RESULTS: 107 patients were analyzed, 66 received a single-shot and 41 a continuous block. No significant differences were found between both blocks at any time point for median MME consumption or pain scores. MME [IQR]: preoperative 20.5 [6.0,48.8] vs. 24.0 [8.8,48.0], p=0.95; POD0 6.0 [0.0,18.6] vs. 10.0 [0.0,14.0], p=0.52; POD1 12.0 [0.0,30.0] vs. 18.0 [5.0,24.0], p=0.69; POD2 6.0 [0.0,21.2] vs. 12.0 [0.0,24.0], p=0.54. VAS [IQR]: preoperative 4.0 [2.2,5.3] vs. 4.6 [3.2,5.3], p=0.34; POD0 1.3 [0.0,3.7] vs. 2.5 [0.0,3.6], p=0.73; POD1 2.9 [1.7,4.4] vs. 3.7 [1.5,4.7], p=0.59; POD2 2.4 [1.0,4.4] vs. 3.3 [1.9,4.2], p=0.18. Preoperative MME/hr significantly decreased after the block for both groups: 1.05 [0.0,2.2] to 0.0 [0.0,0.0], p < 0.001; 1.4 [0.6,3.1] to 0.0 [0.0,0.1], p < 0.001. The reduction in MME/hr between groups was not significantly different: 0.9 [0.0,1.9] vs. 1.4 [0.6,3.1], p = 0.067. We found no significant differences in secondary outcomes between groups. CONCLUSIONS: We report no differences in opioid use and pain scores between single-shot and continuous catheter fascia iliaca nerve blocks. Both blocks similarly reduce preoperative opioid consumption.

Time to Block: Early Regional Anesthesia Improves Pain Control in Geriatric Hip Fractures.

BACKGROUND: Fascia iliaca nerve blocks (FIBs) anesthetize the thigh and provide opioid-sparing analgesia for geriatric patients with hip fracture awaiting a surgical procedure. FIBs are recommended for preoperative pain management; yet, block administration is often delayed for hours after admission, and delays in pain management lead to worse outcomes. Our objective was to determine whether opioid consumption and pain following a hip fracture are affected by the time to block (TTB). We also examined length of stay and opioid-related adverse events. METHODS: This prospective cohort study included patients who were ≥60 years of age, presented with a hip fracture, and received a preoperative FIB from March 2017 to December 2017. Individualized care timelines, including the date and time of admission, block placement, and surgical procedure, were created to evaluate the effect that TTB and time to surgery (TTS) had on outcomes. Patterns among TTB, TTS, and morphine milligram equivalents (MME) were investigated using the Spearman rho correlation. For descriptive purposes, we divided patients into 2 groups based on the median TTB. Multivariable regression for preoperative MME and length of stay was performed to assess the effect of TTB. RESULTS: There were 107 patients, with a mean age of 83.3 years, who received a preoperative FIB. The median TTB was 8.5 hours. Seventy-two percent of preoperative MME consumption occurred before block placement (pre-block MME). A longer TTB was most strongly correlated with pre-block MME (rho = 0.54; p < 0.001), and TTS was not correlated. Patients with a faster TTB consumed fewer opioids preoperatively (12.0 compared with 33.1 MME; p = 0.015), had lower visual analog scale scores for pain on postoperative day 1 (2.8 compared with 3.5 points; p = 0.046), and were discharged earlier (4.0 compared with 5.5 days; p = 0.039). There were no differences in preoperative pain scores, postoperative opioid consumption, delirium, or opioid-related adverse events. Multivariate regression showed that every hour of delay in TTB was associated with a 2.8% increase in preoperative MME and a 1.0% increase in the length of stay. CONCLUSIONS: Faster TTB in geriatric patients with hip fracture may reduce opioid use, pain, and length of stay. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Acute total hip arthroplasty versus open reduction internal fixation for posterior wall acetabular fractures in middle-aged patients.

INTRODUCTION: Open reduction internal fixation (ORIF) is the standard of care for displaced acetabular fractures, but the inability to achieve anatomic reduction, involvement of the posterior wall, articular impaction, and femoral head cartilaginous injury are known to lead to poorer outcomes. Acute total hip arthroplasty (THA) is a reasonable treatment option for older patients with an acetabular fracture and risk factors for a poor outcome, but it is only described in case series. The purpose of this study is to compare outcomes of ORIF and acute THA in middle-aged patients with an acetabular fracture from a single center. METHODS: Retrospective case-controlled study of patients aged 45 to 65 years old with acetabular fractures involving the posterior wall treated with acute THA or ORIF at a level 1 trauma center between 1996 and 2011. Patients were matched by fracture pattern and age at a 2 (ORIF):1 (acute THA) ratio. Functional outcome, complications, and reoperation rates of acute THA and ORIF were compared. RESULTS: Sixteen acute THA patients (average age 56.4 years) and 32 ORIF patients (average age 54.3 years) were evaluated at an average follow-up of 6.2 years (range 1-15.2). The average Oxford Hip Score in the acute THA group was 44 compared to 40 in the ORIF group (P = .075). Complication rates were similar between both the groups. Twelve hips (37%) in the ORIF group had undergone THA or been referred for THA, and 2 revisions (13%) had occurred in the acute THA group. A Kaplan-Meier survival analysis showed that those undergoing acute THA had significantly better survival of their index procedure (P = .031). CONCLUSIONS: Both ORIF and acute THA for high-energy acetabular fractures involving the posterior wall in middle-aged patients can provide excellent results, with acute THA patients achieving improved survival of the index procedure and improved functional scores.

Nationwide Analysis of Femoral Neck Fractures in Elderly Patients: A Receding Tide.

BACKGROUND: Geriatric femoral neck fractures are associated with substantial morbidity and medical cost. We evaluated the incidence and management trends of femoral neck fractures in recent years in the U.S. METHODS: Patient data from 2003 through 2013 were obtained from the Nationwide Inpatient Sample database. Femoral neck fractures in patients ≥65 years old were identified and grouped using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedure codes for internal fixation, hemiarthroplasty, or total hip arthroplasty (THA). The nationwide incidence of femoral neck fractures was calculated and presented as an age-adjusted population rate. Univariable methods were used for trend analysis and comparisons between groups. Logistic regression modeling was used to analyze complications. RESULTS: From 2003 to 2013, we identified 808,940 femoral neck fractures in patients ≥65 years old. The national age-adjusted incidence of femoral neck fractures decreased from 242 per 100,000 U.S. adults in 2003 to 146 in 2013. The proportion of fractures managed operatively with THA increased over time (5.9% in 2003 versus 7.4% in 2013; p < 0.001). Concurrently, the use of hemiarthroplasty declined (65.1% versus 63.6%; p < 0.001). In 2013, the median age of the patients treated with THA was significantly younger (77.3 years) compared with that in the hemiarthroplasty and internal fixation groups (83.2 and 82.0 years). The THA group had significantly higher median initial hospital costs ($17,097) compared with the hemiarthroplasty and internal fixation groups ($14,776 and $10,462). CONCLUSIONS: In the last decade, the total number and population rate of femoral neck fractures in the elderly declined significantly. There was a modest but significant increase in the utilization of THA. CLINICAL RELEVANCE: This report identifies the changing trends in clinical practice in the treatment of geriatric femoral neck fractures in the U.S. Treating physicians should be aware of these trends, which include a decreasing national incidence of geriatric femoral neck fractures as well as an increase in the use of THA.

Increasing Use of Reverse Total Shoulder Arthroplasty for Proximal Humerus Fractures in Elderly Patients.

This study described surgical treatment patterns for proximal humerus fractures among elderly patients, focusing on reverse total shoulder arthroplasty (TSA), and evaluated how the type of fixation affects inpatient factors (cost, length of stay), transfusion rates, and patient disposition (home vs skilled nursing facility). With Nationwide Inpatient Sample data from 2011 to 2013, the authors identified patients 65 years and older who had proximal humerus fractures and divided them into 3 groups: (1) open reduction and internal fixation (ORIF); (2) hemiarthroplasty; and (3) reverse TSA. From 2011 to 2013, 38,729 surgically treated proximal humerus fractures were identified. The rate of reverse TSA increased 1.8-fold during this time, from 13% of operative cases in 2011 to 24% of operative cases in 2013 (P<.001). At the same time, the rates of hemiarthroplasty and ORIF decreased (hemiarthroplasty, from 28% to 21%; ORIF, from 59% to 55%). Although reverse TSA accounted for 32.2% of arthroplasty procedures for proximal humerus fractures in 2011, this value was 53.3% in 2013 (P<.001). In 2013, mean total hospital cost for reverse TSA was $24,154, which was significantly higher than that for ORIF ($16,269) or hemiarthroplasty ($19,175) (P<.001). In a multivariable model, patients undergoing reverse TSA were less likely than those undergoing hemiarthroplasty to be discharged to a skilled nursing facility (odds ratio, 0.75; P=.027). The national rate of reverse TSA nearly doubled from 2011 to 2013. As of 2013, reverse TSA replaced hemiarthroplasty as the most commonly performed arthroplasty procedure for proximal humerus fractures for patients 65 years and older. Patients undergoing reverse TSA were more likely than those undergoing hemiarthroplasty to be discharged home. [Orthopedics. 2017; 40(6):e982-e989.].

Primary total elbow arthroplasty for distal humeral fractures in elderly patients: a nationwide analysis.

BACKGROUND: Displaced intra-articular distal humeral fractures are a challenging injury in elderly patients. High rates of complications have led to the increasing use of total elbow arthroplasty (TEA) for primary treatment. This study presents US nationwide trends in primary TEA for distal humeral fractures in elderly patients (65 years and older) from 2002 to 2012. We hypothesized that there was an increase in the rate of TEA utilization. METHODS: Data were obtained from the Nationwide Inpatient Sample for the years 2002 to 2012. All inpatients 65 years and older with distal humeral fractures were identified and were divided into 2 subgroups based on the operation they received: (1) TEA and (2) open reduction-internal fixation (ORIF). RESULTS: Between 2002 and 2012, the annual frequency of TEA for elderly patients with distal humeral fractures increased 2.6-fold, with 147 patients in 2002 and 385 in 2012. In 2012, TEA was performed in 13% of operatively treated distal humeral fractures compared with only 5.1% in 2002 (P < .05). Mean hospital charges increased significantly for both the ORIF and TEA groups from 2002 to 2012. The average hospital charge for TEA in 2012 was $85,365, which was $16,358 higher than that for patients who underwent ORIF (P < .05). CONCLUSION: The national rate of primary TEA for the acute management of distal humeral fractures in elderly patients has increased significantly over the past 10 years. Given the significant complexity, long-term restrictions, and risks associated with TEA, this increasing trend should be analyzed closely.

Reaming Does Not Affect Functional Outcomes After Open and Closed Tibial Shaft Fractures: The Results of a Randomized Controlled Trial.

OBJECTIVES: We sought to determine the effect of reaming on 1-year 36-item short-form general health survey (SF-36) and short musculoskeletal function assessment (SMFA) scores from the Study to Prospectively Evaluate Reamed Intramedullary Nails in patients with Tibial Fractures. DESIGN: Prospective randomized controlled trial.1319 patients were randomized to reamed or unreamed nails. Fractures were categorized as open or closed. SETTING: Twenty-nine academic and community health centers across the US, Canada, and the Netherlands. PATIENTS/PARTICIPANTS: One thousand three hundred and nineteen skeletally mature patients with closed and open diaphyseal tibia fractures. INTERVENTION: Reamed versus unreamed tibial nails. MAIN OUTCOME MEASUREMENTS: SF-36 and the SMFA. Outcomes were obtained during the initial hospitalization to reflect preinjury status, and again at the 2-week, 3-month, 6-month, and 1-year follow-up. Repeated measures analyses were performed with P < 0.05 considered significant. RESULTS: There were no differences between the reamed and unreamed groups at 12 months for either the SF-36 physical component score [42.9 vs. 43.4, P = 0.54, 95% Confidence Interval for the difference (CI) -2.1 to 1.1] or the SMFA dysfunction index (18.0 vs. 17.6, P = 0.79. 95% CI, -2.2 to 2.9). At one year, functional outcomes were significantly below baseline for the SF-36 physical componentf score, SMFA dysfunction index, and SMFA bothersome index (P < 0.001). Time and fracture type were significantly associated with functional outcome. CONCLUSIONS: Reaming does not affect functional outcomes after intramedullary nailing for tibial shaft fractures. Patients with open fractures have worse functional outcomes than those with a closed injury. Patients do not reach their baseline function by 1 year after surgery.

Temporising external fixation of calcaneus fractures prior to definitive plate fixation: a case series.

INTRODUCTION: Surgical management of calcaneus fractures is technically demanding and has a high risk of wound complications. These fractures are traditionally managed with splinting until swelling has subsided, which can take weeks and leaves the fracture fragments displaced. We describe a novel protocol for the management of displaced intraarticular calcaneus fractures that utilises a temporising external fixator and staged conversion to plate fixation through a sinus tarsi approach. The goal of this technique was to enable earlier treatment with open reduction and internal fixation, minimise the amount of manipulation required at the time of definitive fixation and reduce the wound complication rate seen with the traditional extensile approach. METHODS: The records of patients with displaced calcaneus fractures from 2010-2014 were reviewed retrospectively. A total of nine patients with 10 calcaneus fractures were treated using this protocol. All patients underwent ankle-spanning medial external fixation within 48 hours after injury. Patients underwent conversion to open plate fixation through a sinus tarsi approach when skin turgor had returned to normal. Time to surgery, infection rate, wound complications, radiographic alignment, and time to radiographic union were recorded. RESULTS: The average Bohler's angle improved from 13.2 (range -2 to 34) degrees preoperatively to 34.3 (range 26 to 42) degrees postoperatively. The average time from external fixation to conversion to internal fixation was 4.8 (range 3 to 7) days. There were no immediate post-surgical complications. The average time to weight-bearing was 8.5 weeks. The average time to radiographic union was 9.5 (range 8 to 12) weeks. There were no infections or wound complications at the time of last follow-up. CONCLUSION: Early temporising external fixation for the acute management of displaced calcaneus fractures is a safe and effective method to reduce and stabilise the foot and may decrease the time to definitive fixation. There were no complications related to the use of the external fixator in this series.

Mid-term outcomes in HIV-positive patients after primary total hip or knee arthroplasty.

We hypothesized that infection rates following total joint arthroplasty (TJA) in those with the human immunodeficiency virus (HIV) without hemophilia or drug use would be similar to rates in HIV-negative patients. Records at an urban HIV referral hospital were searched for patients who underwent primary total hip and knee arthroplasty from 2003 to 2010. The primary outcome was revision for infection. 372 HIV-negative and 22 HIV-positive TJA patients met inclusion criteria. The HIV-positive group had more deep infections than the HIV-negative group (9.1% v 2.2%, P=0.102). There were no infections in those with AIDS-defining CD4 counts. Those with HIV may have a higher risk of developing a deep infection. A low CD4 count is not an absolute contraindication to TJA in HIV positive patients.

Comorbidities and perioperative complications in HIV-positive patients undergoing primary total hip and knee arthroplasty.

BACKGROUND: Highly active antiretroviral therapy has prolonged the lifespan of individuals infected with human immunodeficiency virus (HIV). We hypothesized that the number of primary total joint arthroplasties performed in this population has been increasing and that HIV infection is not an independent risk factor for postoperative complications. METHODS: The Nationwide Inpatient Sample for the years 2000 through 2008 was queried to identify patients who underwent primary total joint arthroplasty. HIV, comorbidities, and complications were identified with use of ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification) codes. Data were analyzed with use of multivariate logistic regression, the Pearson chi-square test, and the Mann-Kendall trend test. RESULTS: Of the estimated 5,681,024 admissions for primary total hip and knee arthroplasty in the United States during this period, 8229 (0.14%) were in patients who had HIV. Compared with HIV-negative patients (controls), infected patients were more likely to be younger, be male, and have a history of osteonecrosis, liver disease, drug use, and coagulopathy. The number of total hip and total knee arthroplasties in HIV-positive patients increased from 2000 to 2008 (p < 0.05). Seventy-nine percent (6499) of the total joint arthroplasties in the HIV-positive patients involved the hip. Compared with HIV-negative patients undergoing total hip arthroplasty, HIV-positive patients were more likely to develop acute renal failure (1.3% compared with 0.8%, p = 0.04), develop a wound infection (0.6% compared with 0.3%, p = 0.02), and undergo postoperative irrigation and debridement (0.2% compared with 0.1%, p = 0.01). They were less likely to have a myocardial infarction (0.4% compared with 0.9%, p = 0.04). There was no difference in total complications (8.3% compared with 7.8%, p = 0.52). Similarly, there was no difference in total complications in patients undergoing total knee arthroplasty (7.8% compared with 8.0%, p = 0.76). HIV was not an independent risk factor for complications in total hip arthroplasty (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.95 to 1.47) or total knee arthroplasty (OR, 0.78; 95% CI, 0.49 to 1.25). CONCLUSIONS: The incidence of primary total joint arthroplasty in HIV-positive patients has been increasing. These patients were at slightly higher risk of certain immediate postoperative complications because of a higher rate of medical comorbidities. HIV infection was not an independent risk factor for the total rate of perioperative complications. LEVEL OF EVIDENCE: Prognostic Level II.
