Lost in the Shuffle: Low Health Literacy in Geriatric Fracture Patients and Families Regarding Post-Acute Care-A Prospective Study.

INTRODUCTION: This study aims to evaluate health literacy (HL) in geriatric orthopaedic trauma patients and their families as it relates to their post-acute care (PAC) in skilled nursing facilities (SNFs) and inpatient rehabilitation facilities (IRFs). METHODS: This nonrandomized controlled clinical trial included patients aged 65 years and older treated for acute fracture at a Level 1 trauma center and discharged to either IRF or SNF. First 106 patients enrolled served as the control group and received standard discharge instructions. The second 101 patients were given a set of oral and written instructions regarding PAC detailing important questions to ask upon arrival to their facility. RESULTS: The mean HL score for all patients/families was 2.4 out of 5. No significant difference was noted in HL scores (2.4 versus 2.3) or median LOS (22 versus 28 days) between the control and intervention groups. Family involvement (68%) slightly improved HL scores (2.6 versus 1.9, P < 0.001). Patients discharged to IRF had better HL scores (3.4 versus 2.3, P < 0.001), shorter LOS (median 15 vs 30 days, P < 0.001), and trended toward improved knowledge of discharge goals (48.1% versus 35.6%) than those in SNF. CONCLUSION: System-wide solutions are necessary to improve geriatric HL and optimize outcomes in orthopaedic trauma.

Outcomes After Acute Versus Staged Fixation of Complete Articular Tibial Plafond Fractures.

OBJECTIVE: To determine the outcomes after acute versus staged fixation of complete articular tibial plafond fractures. DESIGN: Retrospective cohort study. SETTING: Single Level 1 Trauma center. PARTICIPANTS: 98 skeletally mature patients with OTA/AO 43C type fractures who underwent definitive fixation with plate and screw constructs and had a minimum 6 months of follow-up. INTERVENTION: Acute open reduction internal fixation (aORIF) versus staged (sORIF) definitive fixation. MAIN OUTCOME MEASUREMENT: Rates of wound dehiscence/necrosis and deep infection. RESULTS: Acute (N = 40) versus staged (N = 58) ORIF groups had comparable rates of vascular disease, renal disease, and substance/nicotine use, but aORIF patients had higher rates of diabetes mellitus (10% vs. 0%, P < 0.001), which correlated with higher American Society of Anaesthesiologist scores (>American Society of Anaesthesiologist 3: 37.5% vs. 13.8%, P = 0.02). Both groups achieved anatomic/good reductions, as determined by postoperative CT scans, at rates greater than 90%; however, the sORIF group required modestly longer operative times to achieve this outcome (aORIF vs. sORIF: 121 vs. 146 minutes, P = 0.02). Postoperatively, both groups had similar rates of wound dehiscence (2.5% vs. 6.9%, P = 0.65), superficial infections (10% vs. 17.2%, P = 0.39), and deep infections (10% vs. 8.6%, P = 0.99). While the injury pattern itself required free flap coverage in 1 patient in each group, unplanned free flap coverage occurred in 10.0% and 10.3% of aORIF and sORIF groups, respectively. Overall, rates of unplanned reoperations, excluding ankle arthrodesis, did not differ between groups (aORIF vs. sORIF:12.5% vs. 25.9%, P = 0.13). CONCLUSIONS: In select patients managed by fellowship-trained orthopaedic traumatologists, acute definitive pilon fixation can produce acceptable outcomes. LEVEL OF EVIDENCE: Therapeutic Level III.

Immediate Weight Bearing as Tolerated Is Safe Following Intramedullary Fixation of Extra-articular Metaphyseal Proximal Tibia Fractures (OTA/AO 41-A).

OBJECTIVES: To determine whether immediate weight bearing after intramedullary fixation of extra-articular proximal tibia fractures (OTA/AO 41A) results in change of alignment before union. DESIGN: Retrospective Review. SETTING: Level I and Level II Trauma Center. PATIENTS/PARTICIPANTS: Thirty-seven patients with 37 proximal tibial fractures, all whom could bear weight as tolerated postoperatively. Eighteen fractures were OTA/AO 41-A2, and 19 were OTA/AO 41-A3. INTERVENTION: Intramedullary nailing of extra-articular proximal tibia fractures. MAIN OUTCOME MEASUREMENTS: Change in fracture alignment or loss of reduction. RESULTS: The average change in coronal alignment at the final follow-up was 1.22 ± 1.28 degrees of valgus and 1.03 ± 1.05 degrees of extension in the sagittal plane. Twenty-five patients demonstrated excellent initial alignment, 10 patients demonstrated acceptable initial alignment, and 2 patients demonstrated poor initial alignment. Five patients demonstrated a change in alignment from excellent to acceptable at the final follow-up. No patient went from excellent or acceptable initial alignment to poor final alignment. Five patients required unplanned secondary surgical procedures. Two patients required return to the operating room for soft-tissue coverage procedures, 2 patients required surgical debridement of a postoperative infection, and 1 patient underwent debridement and exchange nailing of an infected nonunion. No patient underwent revision for implant failure or loss of reduction. CONCLUSION: Immediate weight bearing after intramedullary fixation of extra-articular proximal tibia fractures (OTA/AO 41A) led to minimal change in alignment at final postoperative radiographs. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

A Prospective Randomized Controlled Trial Comparing Enoxaparin & Rivaroxaban for Venous Thromboembolism Prophylaxis in Orthopaedic Trauma.

OBJECTIVES: To determine whether there is a difference in orthopaedic trauma patient medication satisfaction and adherence using an oral versus subcutaneous injectable anticoagulant for venous thromboembolism chemoprophylaxis. DESIGN: Randomized controlled trial. SETTING: Single academic Level 1 trauma center. PARTICIPANTS: One hundred twenty adult orthopaedic trauma patients with operative pelvic or lower extremity fractures were randomized and completed the study. INTERVENTION: Three weeks of either the service standard 40 mg once daily enoxaparin versus trial medication 10 mg once daily rivaroxaban postoperatively. MAIN OUTCOME MEASURES: Patient satisfaction as measured by the Treatment Satisfaction Questionnaire for Medication (TSQM-9). Medication adherence as measured by the Morisky Medication Adherence Scale (MMAS-8). RESULTS: Medication adherence was similar in both groups. Medication satisfaction was significantly higher in the oral rivaroxaban group based on the TSQM-9 and patient-reported data. Secondary outcomes found no significant difference in the incidence of bleeding events or clinically relevant venous thromboembolism. The enoxaparin group experienced more adverse medication-related events. The rivaroxaban medication regimen costs 7.5-10× less out of pocket for uninsured patients. CONCLUSION: The results of this randomized controlled trial demonstrate that patients with surgical orthopaedic trauma prefer an oral anticoagulant for postoperative venous thromboembolism chemoprophylaxis and suggest that rivaroxaban may be a viable option. Furthermore, large-scale studies are needed to confirm safety and efficacy for rivaroxaban in this population as a potential alternative to enoxaparin and aspirin. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Outcomes of Various Antibiotic Cement-Coated Intramedullary Implants on the Treatment of Long Bone Septic Nonunion.

OBJECTIVE: To determine the effectiveness of various types of antibiotic-coated intramedullary implants in the treatment of septic long bone nonunion. DESIGN: Retrospective chart review. SETTING: Level 1 trauma center. PARTICIPANTS: Forty-one patients with septic long bone nonunion treated with an antibiotic cement-coated intramedullary implant. INTERVENTION: Surgical debridement and placement of a type of antibiotic-coated intramedullary implant. MAIN OUTCOME MEASUREMENTS: Union and need for reoperation. RESULTS: At an average 27-month follow-up (6-104), 27 patients (66%) had a modified radiographic union score of the tibia of 11.5 or greater, 12 patients (29%) a score lower than 11.5, and 2 patients (5%) underwent subsequent amputation. Six patients underwent no further surgical procedures after the index operation. Patients treated with a rigid, locked antibiotic nail achieved earlier weight-bearing (P = 0.001), less frequently required autograft (P = 0.005), and underwent fewer subsequent procedures (average 0.38 vs. 3.60, P = 0.004) than those treated with flexible core antibiotic rods. CONCLUSIONS: Antibiotic-coated intramedullary implants are successful in the treatment of septic nonunions in long bones. In our cohort, rigid, statically locked nails allowed faster rehabilitation, decreased the need for autograft, and decreased the number of additional surgical procedures. Further study is needed to confirm these findings. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Physician wellness in orthopaedic surgery : a multinational survey study.

AIMS: Physician burnout and its consequences have been recognized as increasingly prevalent and important issues for both organizations and individuals involved in healthcare delivery. The purpose of this study was to describe and compare the patterns of self-reported wellness in orthopaedic surgeons and trainees from multiple nations with varying health systems. METHODS: A cross-sectional survey of 774 orthopaedic surgeons and trainees in five countries (Australia, Canada, New Zealand, UK, and USA) was conducted in 2019. Respondents were asked to complete the Mayo Clinic Well-Being Index and the Stanford Professional Fulfillment Index in addition to 31 personal/demographic questions and 27 employment-related questions via an anonymous online survey. RESULTS: A total of 684 participants from five countries (Australia (n = 74), Canada (n = 90), New Zealand (n = 69), UK (n = 105), and USA (n = 346)) completed both of the risk assessment questionnaires (Mayo and Stanford). Of these, 42.8% (n = 293) were trainees and 57.2% (n = 391) were attending surgeons. On the Mayo Clinic Well-Being Index, 58.6% of the overall sample reported feeling burned out (n = 401). Significant differences were found between nations with regards to the proportion categorized as being at risk for poor outcomes (27.5% for New Zealand (19/69) vs 54.4% for Canada (49/90) ; p = 0.001). On the Stanford Professional Fulfillment Index, 38.9% of the respondents were classified as being burned out (266/684). Prevalence of burnout ranged from 27% for Australia (20/74 up to 47.8% for Canadian respondents (43/90; p = 0.010). Younger age groups (20 to 29: RR 2.52 (95% confidence interval (CI) 1.39 to 4.58; p = 0.002); 30 to 39: RR 2.40 (95% CI 1.36 to 4.24; p = 0.003); 40 to 49: RR 2.30 (95% CI 1.35 to 3.9; p = 0.002)) and trainee status (RR 1.53 (95% CI 1.15 to 2.03 p = 0.004)) were independently associated with increased relative risk of having a 'at-risk' or 'burnout' score. CONCLUSIONS: The rate of self-reported burnout and risk for poor outcomes among orthopaedic surgeons and trainees varies between countries but remains unacceptably high throughout. Both individual and health system characteristics contribute to physician wellness and should be considered in the development of strategies to improve surgeon wellbeing.

Patient Perception of Pain Control (Not Opiate Amount) Affects Hospital Consumer Assessment of Healthcare Providers and Systems and Press Ganey Satisfaction Scores After Orthopaedic Trauma.

INTRODUCTION: Opiate abuse is a public health issue linked to prescribing. Prescribing increased partly in response to adopting pain as the fifth vital sign. Assessing pain control on patient satisfaction surveys, including government-mandated Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) and optional private surveys (Press Ganey) administered on hospital discharge, may contribute. This study evaluates whether opiate amounts affect orthopaedic trauma patient perception of pain control and overall hospital rating on HCAHPS and Press Ganey surveys. METHODS: Consecutive adult patients >18 years surgically treated for isolated fractures (UE = upper extremity, LE = lower extremity, and PA = pelvis/acetabulum) at a level 1 trauma center between January 1, 2014, and December 31, 2016, were retrospectively analyzed. Hospital charts, HCAHPS, and Press Ganey data were reviewed; patients without survey responses were excluded. Data included comorbidities, psychiatric history, substance use, injury type, and surgery. Analysis included Spearman's rho for correlations, Wilcoxon rank-sum and Kruskal-Wallis for continuous variables, and adjusted ordinal regression to estimate association between opioid prescribing and patient ratings. RESULTS: One hundred fifty-two total patients (UE 29, LE 112, and PA 11) with mean age of 57 years and median length of stay 3 days were included. Adjusted models showed longer duration outpatient prescriptions were associated with lower rating on how often inpatient pain was controlled (P = 0.002), lower total MME inpatient was associated with higher ratings (HCAHPS P = 0.015; Press Ganey, P = 0.03), lower average daily MME inpatient was associated with lower ratings (HCAHPS P = 0.008; Press Ganey, P = 0.037), and shorter outpatient prescription duration was associated with lower ratings (P = 0.008). Patient perception of pain control was strongly associated with overall HCAHPS (P < 0.05) and Press Ganey (P < 0.001) ratings. DISCUSSION: Inpatient and outpatient opiate amounts and duration demonstrated some associations with overall scores. However, patients' pain control perception seems to have the strongest relationship with hospital rating. Counseling and multimodal pain control may lead to strong satisfaction scores without needing high opiates after orthopaedic trauma.

Cervical length change as a predictor of preterm birth in symptomatic patients.

BACKGROUND: Distinguishing between true and false preterm labor remains a challenge. The shortening in cervical length throughout a gestation has been theorized to be a possible predictor of spontaneous preterm birth. Although there are some studies evaluating cervical length shortening as a predictor of spontaneous preterm birth, it is not known whether the shortening in cervical length from an asymptomatic to symptomatic state, when a patient presents with preterm labor symptoms, is predictive of spontaneous preterm birth. OBJECTIVE: This study aimed to determine the utility of cervical length shortening from an asymptomatic time point (anatomic ultrasound) to when a patient presents with preterm labor symptoms as a predictor of spontaneous preterm birth. STUDY DESIGN: A prospective cohort study was performed to evaluate the use of transvaginal cervical length assessment in symptomatic women in predicting spontaneous preterm birth from January 2013 to March 2015. Women with singleton gestations who presented to our institution between 22 0/7 weeks and 33 6/7 weeks of gestation with preterm labor symptoms were included in the overall cohort. This was a planned secondary analysis to evaluate the shortening in cervical length from an asymptomatic state (anatomic ultrasound) to a symptomatic state as a predictor of preterm birth. For this analysis, inclusion criteria were known delivery status, cervical length screening performed at anatomic ultrasound, and a valid cervical length measurement at the time of preterm labor symptoms. Women with preterm rupture of membranes, cervical dilation of >2 cm, or moderate to severe bleeding were excluded. Cervical length shortening was defined as a decrease in cervical length of >10 mm from anatomic ultrasound to the time of presentation with preterm labor symptoms. The outcome evaluated was spontaneous preterm birth before 37 weeks of gestation. Chi-square test and receiver operating characteristic curves were used to evaluate the data. Multivariable logistic regression was used to calculate the odds. Test characteristics of cervical length shortening of >10 mm were determined. RESULTS: A total of 549 women were included in the original cohort, and 277 women were included in this secondary analysis. The overall rate of spontaneous preterm birth was 8.3%. There were 52 women (19%) with cervical length shortening of >10 mm. The rate of spontaneous preterm birth was significantly higher for those with cervical length shortening of >10 mm than those with cervical length shortening of ≤10 mm (21.2% vs 5.3%; P=.001). This higher risk of spontaneous preterm birth remained after adjusting for confounders including maternal age and previous spontaneous preterm birth (adjusted odds ratio, 4.71; 95% confidence interval, 1.84-12.09). Using cervical length shortening of >10 mm as a screening test had a sensitivity of 47.8%, a specificity of 83.9%, a positive predictive value of 21.2%, and a negative predictive value of 94.7%. CONCLUSION: In women presenting with preterm labor symptoms, a cervical length that is >10 mm shorter from anatomic ultrasound is associated with an increased risk of spontaneous preterm birth.

Symptoms and Clinical Outcomes of Coronavirus Disease 2019 in the Outpatient Setting.

Because most cases of coronavirus disease 2019 (COVID-19) are not severe, understanding the epidemiology of mild cases has important clinical implications. We aimed to describe the symptom profile and associated outcomes in a virtual outpatient COVID-19 clinic. We conducted a prospective cohort study from March through June 2020. We included 106 patients with positive results for SARS-CoV-2, followed up until they had 2 sequential negative tests. Exploratory regression analyses identified potential prognostic symptoms or risk factors associated with outcomes, including emergency department (ED) visits, hospitalizations, and time to resolution of viral shedding. The mean (range) patient age was 51 (18-86) years, 50% were men, and 36.5% had at least 1 risk factor, most commonly asthma (16%) and diabetes (10%). Most patients (98.1%) had symptoms-cough (80.4%), fatigue (67.6%), fever (66.0%), headache (49.0%), and ageusia (46.9%). Nine (8.5%) patients were admitted to the ED, 5 (4.7%) were hospitalized, and none died. Asthma (RR = 7.13, P = .001) and being immunocompromised (RR = 3.44, P = .03) were associated with higher risks of adverse outcomes. Asthma (HR = 0.56, P = .04) and early symptoms of ageusia (HR= 0.50, P = .01) or myalgia (HR = 0.63, P = .04) were associated with significantly longer duration of viral shedding. In contrast to reports about severe cases of COVID-19, we found a higher incidence of sinus symptoms, gastrointestinal symptoms, and myalgia and a lower incidence of fever, anosmia, and ageusia among our mild/moderate cases. Asthma and immunocompromised status were associated with adverse outcomes, and asthma and early symptoms of ageusia or myalgia with significantly longer duration of viral shedding.

Twenty-Year Trends in Upper-Extremity Infections at a Single Urban Institution.

Purpose: Empiric antibiotic therapy for hand and upper-extremity infections aims to cover the most common causative organisms, which may change over time. The purpose of this study was to investigate the changes in the bacterial profile of upper-extremity infections over 2 decades at our institution. Methods: We performed a retrospective chart review of patients with upper-extremity infections treated at a single level 1 trauma center between 2001 and 2019. Patients older than 18 years who underwent surgical treatment for infection with operative cultures available were included. Patient demographics, comorbidities, and culture results were reviewed. Then, the distribution of organisms was analyzed for overall prevalence, and the profile of 2001-2010 was compared with that of 2010-2019 using a chi-square test. Results: A total of 237 patients (mean age, 43 years) met the criteria and were included in the study. Over the entire study period, the most isolated organism was Staphylococcus aureus, specifically the methicillin-resistant species. Methicillin-resistant S aureus remained the most common organism in both decades but declined over time from 47% in 2001-2010 to 27% in 2010-2019 (P < .05). There was a significant increase in the proportion of Streptococcus infections (from 6% to 17%; P < .05) and in polymicrobial infections (aerobic 8% to 28%, anaerobic 0% to 14%; P < .05). Enterobacter species were not isolated in 2001-2010 but comprised 13% of infections in the second decade (P < .05). Conclusions: Methicillin-resistant S aureus remains the most common organism isolated from upper-extremity infections, though there has been a decline over the last 20 years. Conversely, Streptococcal spp., Enterobacter spp. and polymicrobial infections have increased. This study demonstrates longitudinal shifts in the distribution of bacteria responsible for upper-extremity infections at our institution, and these trends can be considered when choosing future empiric therapy. Type of study/level of evidence: Prognostic IV.

Evaluating the impact of a standardized induction protocol to reduce adverse perinatal outcomes: a prospective cohort study.

OBJECTIVE: Our objective was to evaluate the impact of a standardized induction protocol on reducing maternal and neonatal morbidity in women undergoing an induction with an unfavorable cervix. STUDY DESIGN: We performed a prospective cohort study of women undergoing an induction from May 2013 to June 2015. Women who were ≥18 years, ≥37 weeks with intact membranes and an unfavorable cervix (Bishop score of ≤6 and cervical dilation ≤2 cm) with no prior cesarean were included. We compared the following outcomes between women managed with the labor protocol versus women in an observation group, managed at the discretion of the provider: Labor length, cesarean delivery, maternal and neonatal morbidity, and neonatal intensive care unit admission for >48 hours. Multivariable models incorporated confounders specific to each outcome. RESULTS: 855 women were included (491: labor protocol group; 364: observational group). Women in the labor protocol group had a shorter time to delivery (15.7 hours vs. 18.0 hours, p < .001), a decrease in maternal morbidity (7.3% vs. 11.5%, p = .04), lower rates of NICU admission >48 hours (3.5% vs 8%, p = .005), and a lower neonatal morbidity (3.0% vs. 7.7%, p = .003) compared to women in the observational group. There was no difference in rate of cesarean between the labor protocol and observational groups (27.7% vs. 32.7%, p = .13). When adjusting for confounders, women in the labor protocol group had a 60% reduction in NICU admission >48 hours (RR: 0.41, 95% CI: 0.22-0.76) and a 70% reduction in neonatal morbidity (RR: 0.31, 95% CI: 0.13-0.70). Time to delivery and maternal morbidity were not significantly different in adjusted models. CONCLUSION: Utilization of a standardized induction protocol was associated with a significant reduction in neonatal morbidity without increasing the risk of cesarean or maternal morbidity.

"Unstable" Pediatric Femoral Shaft Fractures Treated With Flexible Elastic Nails Have Few Complications.

OBJECTIVES: To determine our complication rate in pediatric femoral shaft fractures treated with flexible elastic nailing and to determine fracture characteristics that may predict complications. DESIGN: Retrospective cohort study. SETTING: One Level 1 and One Level 2 academic trauma centers. PATIENTS/PARTICIPANTS: One hundred one pediatric femoral shaft fractures treated from 2006 to 2018. MAIN OUTCOME MEASUREMENT: Major and minor complications. RESULTS: One hundred one femurs met inclusion criteria. The average age was 7 years (range 3-12 years). The average weight was 29.0 kg (range 16-55 kg). The average follow-up was 11 months (6-36 months). Ninety-three patients underwent elective implant removal at our institution. Fifty-one of the 101 (50%) fractures were "unstable" patterns. Ninety-three percent had implants that filled >80% of the canal (69 titanium and 32 stainless steel). Seventeen percent (18) had cast immobilization. All fractures went on to union. No patient required revision surgery for malunion as follows: 6 had coronal/sagittal malalignment >10 degrees, 3 had malrotation >15 degrees, and none had a leg length inequality >1 cm. Three patients had an unplanned surgery as follows: 2 for prominent implants and 1 for refracture after a second injury. There were no patient, fracture, or treatment characteristics that were predictive of complications or unplanned surgery, including "unstable" fractures (P = 0.78). CONCLUSION: Our study demonstrates that flexible elastic nailing can be safely used in most pediatric femoral shaft fractures, including those previously described as "unstable." LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions to Authors for a complete description of levels of evidence.

Quality of Reduction of Displaced Intra-articular Calcaneal Fractures Using a Sinus Tarsi Versus Extensile Lateral Approach.

OBJECTIVE: To evaluate the difference in the quality of fracture reduction between the sinus tarsi approach (STA) and extensile lateral approach (ELA) using postoperative Computed Tomography (CT) scans in displaced intra-articular calcaneal fractures (DIACFs). DESIGN: Retrospective. SETTING: Level 1 and level 2 academic centers. PATIENTS: Consecutive patients undergoing operative fixation of DIACFs with postoperative CT scans and standard radiographs. METHODS: Patients were identified based on Current Procedural Terminology code and chart review. All operative calcaneal fractures treated between 2012 and 2018 by fellowship-trained orthopaedic trauma surgeons were evaluated. Those with both postoperative CT scans and radiographs were included. Exclusion criteria included extra-articular fractures, malunions, percutaneous fixation, ORIF and primary fusion, and those patients without a postoperative CT scan. The Sanders classification was used. Cases were divided into 2 groups based on ELA versus STA. Bohler angle and Gissane angle were evaluated on plain radiographs. CT reduction quality grading included articular step off/gap within the posterior facet, and varus angulation of the tuberosity: CT reduction grading included: excellent (E): no gap, no step, and no angulation; good (G): <1 mm step, <5 mm gap, and/or <5° of angulation, fair (F): 1-3 mm step, 5-10 mm gap, and/or 5-15° angulation; and poor (P): >3 mm step, >10 mm gap, and/or >15° angulation. RESULTS: Seventy-seven patients with 83 fractures were included. Average age was 42 years (range, 18-74 years), with 57 men. Four fractures were open. There were 37 Sanders II and 46 Sanders III fractures; 36 fractures were fixed using the STA, whereas 47 used the ELA. Average days to surgery were 5 for STA and 14 for ELA (P < 0.001). A normal Bohler angle was achieved more often with the ELA (91.5%) than with STA (77.8%) (P < 0.001). There was no difference by approach for Gissane angle (P = 0.5). ELA had better overall reduction quality (P = 0.02). For Sanders II, there was no difference in reduction quality with STA versus ELA (P = 0.51). For Sanders III, ELA trended toward better reduction quality (P = 0.06). CONCLUSIONS: The ELA had a better overall reduction of Bohler angle on plain radiographs and of the posterior facet and tuberosity on postoperative CT scans. For Sanders type II DIACFs, there was no difference between STA and ELA. Importantly, for Sanders III DIACFs, ELA trended toward better reduction quality. In addition to fracture reduction, surgeon learning curve, early wound complications, and long-term outcomes must be considered in future studies comparing the ELA and STA. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Routine Postoperative Complete Blood Counts Are Not Necessary After Most Primary Total Hip and Knee Arthroplasties.

BACKGROUND: Routine postoperative complete blood count tests are commonplace after total joint arthroplasty. The goal of this study was to identify if these result in any clinically meaningful action and if it would be safe to forego this testing in a population without known risk factors for transfusion. METHODS: A retrospective review of 1060 patients undergoing a total knee or total hip arthroplasty at a single institution was performed. Data points including patient demographics, preoperative and postoperative laboratory results, tranexamic acid use, preoperative and postoperative medication for venous thromboembolism prophylaxis and anticoagulation, as well as 90-day readmission related to anemia were collected. RESULTS: The transfusion rate for all patients was 0.66% (7/1060) and there was only one transfusion for a patient with a preoperative hemoglobin (Hb) greater than 12 g/dL (1/976; 0.1%). There was no difference in the change from preoperative to postoperative day 1 Hb levels in patients treated with aspirin compared with those on direct oral anticoagulation (P = .73). There were no 90-day readmissions related to acute blood loss anemia. CONCLUSIONS: This study demonstrates that routine postoperative complete blood count testing is not absolutely necessary and does not provide additional value in the vast majority of patients with preoperative Hb levels equal to or greater than 12 g/dL when tranexamic acid is administered. This could avoid unnecessary testing in patients and increased savings to the health care system. LEVEL OF EVIDENCE: Level 3, retrospective cohort.

ORIF of Distal Humerus Fractures with Modern Pre-contoured Implants is Still Associated with a High Rate of Complications.

BACKGROUND: The purpose of this study was to identify complications after operative treatment of distal humerus fractures with anatomic, pre-contoured, locking distal humeral plates. We hypothesized that these fractures have high complication rates despite the use of these modern implants. MATERIALS AND METHODS: Between 2010 and 2018, 43 adult patients with a distal humerus fracture underwent open reduction and internal fixation (ORIF) at a Level I trauma center. Pre-operative variables, including medical comorbidities, mechanism of injury, open or closed fracture, AO/OTA fracture classification (Type A, B, or C), and nerve palsy, were recorded. Intra-operative variables including surgical approach, ulnar nerve transposition, and plate configuration were recorded. Anatomic, pre-contoured, locking distal humeral plates were used in all patients. Various plating systems were used based on surgeon preference and fracture pattern. Post-operative complications including infection, nonunion, malunion, painful implants, nerve palsy, heterotopic ossification, stiffness, and post-traumatic arthritis were recorded. RESULTS: Most fractures were Type C (53%). The posterior olecranon osteotomy approach (51%) and parallel plate configuration (42%) were used in most cases. At a mean follow-up of 15 months, the complication rate was 61% (26/43 patients). Among all patients, 49% (21/43 patients) required a reoperation. Elbow stiffness (19%) was the most common complication followed by nerve palsy (16%). There were four fracture nonunions (9%), deep infections (9%), painful implants (9%), post-traumatic arthritis (9%), and heterotopic ossification (9%). CONCLUSIONS: Distal humerus fractures treated with ORIF utilizing anatomic, pre-contoured, locking distal humeral plates have a high complication rate, with many requiring reoperation. LEVEL OF EVIDENCE: Therapeutic Level IV.

Defining the younger patient: age as a predictive factor for outcomes in shoulder arthroplasty.

BACKGROUND: The purpose of this study was to define an age cutoff at which clinical outcomes and revision rates differ for patients undergoing primary anatomic total shoulder arthroplasty (TSA) and patients undergoing primary reverse shoulder arthroplasty (RSA). METHODS: This retrospective cohort study included 1250 primary shoulder arthroplasties (1131 patients) with minimum 2-year clinical follow-up (mean, 50 months [range, 24-146 months]). TSA (n = 518; mean age, 68.1 years [range, 28-90 years]) was performed for osteoarthritis in most cases (99%), whereas the primary diagnoses for RSA (n = 732; mean age, 70.8 years [range, 22-91 years]) included rotator cuff arthropathy (35%), massive cuff tear without osteoarthritis (29.8%), and osteoarthritis (20.5%). Outcomes included range of motion, the American Shoulder and Elbow Surgeons (ASES) score, and the revision rate. The relationship between age at the time of surgery in 5-year increments (46-50 years, 51-55 years, and so on) and the revision rate was examined to identify the age cutoff; this was then used to assess clinical outcomes. RESULTS: In patients younger than 65 years, TSA was associated with a 3.4-fold increased risk of revision (P = .01). RSA performed in patients younger than 60 years was associated with a 4.8-fold increased risk of revision (P < .001). TSA patients aged 65 years or older and RSA patients aged 60 years or older had better total ASES scores (82 vs. 77 [P = .03] and 72 vs. 62 [P = .002], respectively) and better internal rotation (interquartile range, TSA 5-6 vs. 4-5 [P = .002] and RSA 4-5 vs 3-4 [P = .04])-where 6 represents T4 to T6 and 4 represents T11 to L1-than their younger counterparts. CONCLUSION: Age at index arthroplasty affects outcomes and the risk of revision. Primary TSA patients younger than 65 years and RSA patients younger than 60 years have a significantly increased revision risk. These age cutoffs are also correlated with differences in ASES scores and internal rotation.

Does the etiology of a failed hemiarthroplasty affect outcomes when revised to a reverse shoulder arthroplasty?

BACKGROUND: The purposes of this study were to evaluate patient outcomes after revision of hemiarthroplasty to reverse shoulder arthroplasty (RSA) based on initial pathology, to determine the re-revision rate, and to identify characteristics that may predict subsequent re-revision. METHODS: A total of 207 shoulder hemiarthroplasty, bipolar prosthesis, and humeral resurfacing cases revised to RSA between January 2004 and January 2017 were reviewed. Outcome measures included shoulder motion and American Shoulder and Elbow Surgeons and Simple Shoulder Test (SST) scores. Sixteen RSAs underwent re-revision. A case-control study with each revised RSA matched to 4 controls based on age, sex, and minimum 2-year follow-up was performed to evaluate for factors predicting re-revision. RESULTS: The mean time from initial hemiarthroplasty to RSA was 3.6 years (range, 0.1-20 years). There were 114 patients with a minimum of 2 years' follow-up (mean, 57 months; range, 24-144 months). The most common initial diagnoses for hemiarthroplasty were fracture (n = 72), cuff tear arthropathy (CTA) (n = 22), and osteoarthritis (OA) (n = 20). Overall mean scores and range-of-motion values were as follows: American Shoulder and Elbow Surgeons score, 59 (95% confidence interval [CI], 54-64); SST score, 4 (95% CI, 4-5); forward flexion, 106° (95% CI, 96°-116°); and abduction, 95° (95% CI, 85°-105°). Compared with fracture cases, CTA cases had better forward flexion (P = .01) and abduction (P = .006) and OA cases had better SST scores (P = .02) and abduction (P = .04). The re-revision rate was 7.7% at a mean of 31 months (range, 0-116 months), with the most common diagnosis being fracture (10 of 16 cases). Humeral loosening (8 of 16 cases) was the most common failure mechanism, and larger glenosphere sizes were more likely to be revised. CONCLUSION: Functional outcome scores of hemiarthroplasty cases revised to RSA were better for patients with OA than for patients with CTA or fracture. Cases of hemiarthroplasty for fracture had decreased motion after revision to RSA compared with CTA and OA. Humeral loosening was the most common failure mechanism.

Persistent cardiac dysfunction on echocardiography in African American women with severe preeclampsia.

BACKGROUND: Cardiovascular disease (CVD) and preeclampsia both disproportionally affect African American women. Evidence continues to grow linking a history of preeclampsia to future CVD. Therefore, we sought to determine whether abnormalities in cardiac function, as determined by echocardiography, could be identified at the time of preeclampsia diagnosis in African American women, and if they persist into the early postpartum period. STUDY DESIGN: This prospective blinded longitudinal cohort study was performed from April 2015 to May 2017. We identified African American women diagnosed with preterm (<37 weeks) preeclampsia with severe features and compared them to control normotensive pregnant women matched on race, gestational age, maternal age, and body mass index. We obtained transthoracic echocardiograms on cases and controls at time of diagnosis and again 4-12 weeks postpartum. We quantified the systolic function with longitudinal strain, ventricular-arterial coupling parameters and diastolic function. RESULTS: There were 29 matched (case-control) pairs of African American women for a total of 58 women. At time of preeclampsia diagnosis, there was more abnormal cardiac function as evidenced by worse cardiac systolic function (longitudinal strain), increased chamber stiffness (end systolic elastance), and worse diastolic function (E/e') in preeclampsia cases compared to controls. These findings persisted 4-12 weeks postpartum. There were additional notable abnormalities in E/A, and Ea (arterial load) postpartum, indicative of potentially worse diastolic function and increased arterial stiffness in the postpartum period. CONCLUSIONS: Among African American women, we found notable cardiac function differences between women with severe preeclampsia and healthy pregnant controls that persist postpartum.

Effect of Nail Size, Insertion, and Δ Canal-Nail on the Development of a Nonunion After Intramedullary Nailing of Femoral Shaft Fractures.

OBJECTIVE: To determine whether intramedullary nail (IMN) diameter, antegrade versus retrograde insertion, or the difference between the canal and IMN diameter affect femoral shaft fracture healing. DESIGN: Retrospective analysis of a prospective database. SETTING: Level One Regional Trauma Center. PATIENTS/PARTICIPANTS: Seven hundred thirty-three femoral shaft fractures (OTA/AO 32) treated with an IMN between 1999 and 2017. After exclusion criteria, 484 fractures remained in the final analysis. INTERVENTION: Closed section, cannulated, interlocked, titanium alloy IMN using a reamed insertion technique. MAIN OUTCOME MEASUREMENTS: Nonunion, IMN size (10, 11.5, and 13 mm), antegrade versus retrograde insertion, Δ canal-nail diameter (ΔD) after reaming (<1, 1-2, or >2 mm). RESULTS: IMN diameters used were as follows: 314/10 mm (64%), 137/11.5 mm (28%), and 33/13 mm (8%). Forty-five percent were placed in antegrade versus 55% retrograde. Four hundred fifty-six fractures (94.2%) healed uneventfully. There were no IMN failures. 10/484 IMNs (2%) had broken interlocking screws; only 4 were associated with a NU. Average time to union was 23 weeks (12-119). Twenty-eight (5.8%) developed NU. There was no statistical correlation between (1) the NU rate and IMN diameter: 10 mm, 6.3%; 11.5 mm, 5.1%; 13 mm, 3% (P = 0.8, power = 0.85), (2) the NU rate and ΔD: 7.1% <1 mm, 5.6% 1-2 mm, 20% >2 mm (P = 0.36), (3) the NU rate and fracture location: Prox = 11%, Mid = 5%, Dist = 3% (P = 0.13), or (4) the NU rate and antegrade (7.2%) versus retrograde (4.2%) insertion (P = 0.24). CONCLUSION: Similar healing rates occurred regardless of IMN diameter, Δ canal-nail diameter after reaming, or insertion site. This indicates that a closed section, cannulated, interlocked, titanium alloy IMN with a diameter of 10 mm can be considered the standard diameter for the treatment of acute femoral shaft fractures, regardless of entry point. This should be associated with less reaming and therefore shorter operative times, and possibly less hospital implant inventories as well. Larger diameter IMN should be reserved for revision surgery. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Early to midterm results of "low-friction" articulating antibiotic spacers for septic total knee arthroplasty.

BACKGROUND: Infection of total knee arthroplasty is a complex problem often resulting in multiple surgeries for the patient. We examined the early to midterm results of a retained cemented "low-friction" metal-on-polyethylene articulating antibiotic spacer in total knee arthroplasty. METHODS: We retrospectively reviewed patients with a total knee cemented articulating antibiotic spacer performed for joint sepsis. Patients were allowed full weight bearing and normal activities after eradication of the infection at 6 weeks postop. Two months later, patients were given the option of conversion to a revision implant vs retention of the spacer. We examined infection cure rate, mechanical failure, Knee Society Scores, range of motion, and patient factors associated with spacer retention. RESULTS: Fifty-five knees were studied with average follow-up of 1.8 years (0.2-8.4). Among patients choosing spacer retention (40%), the average follow-up time of the spacer was 3.3 years (0.6-8.4). Five patients (9.1%) required a repeat spacer for recurrent infection. CONCLUSIONS: Usage of articulating cement antibiotic spacers with a metal-on-polyethylene bearing couple provides excellent infection eradication, while also resulting in good functional outcomes. Early evidence suggests that use of the implant can be extended beyond typical timeframes and, in certain patient populations, may be suitable for a single-stage procedure.
