RESUMEN
The electrocardiogram is universally used to diagnose ST-segment elevation myocardial infarction and serves as guidance for the interventional cardiologist to identify the acute thrombotic lesion. However, this case illustrates that the electrocardiogram can also be deceiving.
RESUMEN
BACKGROUND: Dedicated prospective studies investigating high-definition intravascular ultrasound (HD-IVUS)-guided primary percutaneous coronary intervention (PCI) are lacking. The aim of this study was to qualify and quantify culprit lesion plaque characteristics and thrombus using HD-IVUS in patients presenting with ST-segment elevation myocardial infarction (STEMI). METHODS: The SPECTRUM study is a prospective, single-center, observational cohort study investigating the impact of HD-IVUS-guided primary PCI in 200 STEMI patients (NCT05007535). The first 100 study patients with a de novo culprit lesion and a per-protocol mandated preintervention pullback directly after vessel wiring were subject to a predefined imaging analysis. Culprit lesion plaque characteristics and different thrombus types were assessed. An IVUS-derived thrombus score, including a 1-point adjudication for a long total thrombus length, long occlusive thrombus length, and large maximum thrombus angle, was developed to differentiate between low (0-1 points) and high (2-3 points) thrombus burden. Optimal cut-off values were obtained using receiver operating characteristic curves. RESULTS: The mean age was 63.5 (±12.1) years and 69 (69.0%) patients were male. The median culprit lesion length was 33.5 (22.8-38.9) mm. Plaque rupture and convex calcium were appreciated in 48 (48.0%) and 10 (10.0%) patients, respectively. Thrombus was observed in 91 (91.0%) patients (acute thrombus 3.3%; subacute thrombus 100.0%; organized thrombus 22.0%). High IVUS-derived thrombus burden was present in 37/91 (40.7%) patients and was associated with higher rates of impaired final thrombolysis in myocardial infarction flow (grade 0-2) (27.0% vs. 1.9%, p < 0.001). CONCLUSIONS: HD-IVUS in patients presenting with STEMI allows detailed culprit lesion plaque characterization and thrombus grading that may guide tailored PCI.

BACKGROUND: In order to facilitate fractional flow reserve (FFR)-guided lesion assessment, several 3-dimensional (3D)-angiography-based physiological indices have been recently validated. Thus far, limited data are available on the association of these indices with conventional forms of ischemia testing. AIM: The aim of the study was to determine the association between 3D-angiography-based vessel-FFR (vFFR) and myocardial ischemia as assessed by exercise electrocardiography (ECG) testing, dobutamine stress echocardiography, single photon emission computed tomography myocardial perfusion imaging (SPECTMPI), and stress cardiovascular magnetic resonance imaging (stress CMR). METHODS: FAST ISCHEMIA is a retrospective, single-center cohort study including patients who underwent non-invasive myocardial ischemia testing and subsequent coronary angiography (≤3 months). A total of 145 patients (340 vessels) were analyzed. The overall patient-based sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+), and negative likelihood ratio (LR-) of vFFR ≤0.80 in any vessel for ischemia was 64% (95% confidence interval [CI], 53-74), 71% (95% CI, 54-84), 83% (95% CI, 72-91), 46% (95% CI, 33-60), 2.16 (95% CI, 1.25-3.74), and 0.52 (95% CI, 0.36-0.74), respectively. Multivariable logistic regression showed that vFFR ≤0.80 was significantly associated with ischemia on a patient level (odds ratio, 8.13; 95% CI, 2.51-30.06; P<.001) and on a vascular territory level (odds ratio, 2.75; 95% CI, 1.17-6.44; P<.01). CONCLUSION: Our study suggests that vFFR ≤0.80 has a modest association with non-invasive myocardial ischemia testing using either exercise ECG or stress imaging modalities. After correcting for independent confounders, vFFR was independently associated with ischemia on a non-invasive myocardial ischemia detection test.

BACKGROUND: An acute Achilles tendon rupture is one of the most common sports injuries, affecting 18 per 100,000 persons, and its operative repair has been evolving and increasing in frequency since the mid-1900s. Traditionally, open surgical repair has provided improved functional outcomes, reduced rerupture rates, and a quicker recovery and return to activities at the expense of increased wound complications such as infections and skin necrosis compared with nonoperative management. In 1977, Ma and Griffith introduced the percutaneous approach, and over the following decades, multiple improved techniques, and modifications thereof, have been described with comparable outcomes with open repair. PURPOSE: The current study aimed to provide updated level 1 evidence comparing open repair with minimally invasive surgery (MIS) through a comprehensive search of the literature published in English, Arabic, Spanish, Portuguese, and German while avoiding limitations of previous studies such as heterogeneous study designs and a small number of included trials. STUDY DESIGN: Meta-analysis; Level of evidence, 1. METHODS: Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, 2 independent team members searched several databases to identify randomized controlled trials (RCTs) comparing open repair and MIS of Achilles tendon ruptures. The primary outcomes were (1) functional outcomes, (2) reruptures, (3) sural nerve injuries, and (4) infections (deep/superficial), whereas the secondary outcomes were (1) skin complications, (2) adhesions, (3) other complications, (4) ankle range of motion, and (5) surgical time. RESULTS: There were 10 RCTs that qualified for the meta-analysis with a total of 522 patients. Overall, 260 (49.8%) patients underwent open repair, while 262 (50.2%) underwent MIS. The mean postoperative AOFAS score was 94.8 and 95.7 for open repair and MIS, respectively, with a nonsignificant difference (mean difference [MD], -0.73 [95% CI, -1.70 to 0.25]; P = .14; I2 = 0%). The pooled mean total complication rate was 15.5% (0%-36.4%) for open repair and 10.4% (0%-45.5%) for MIS, with a nonsignificant statistical difference (odds ratio [OR], 1.50 [95% CI, 0.87-2.57]; P = .14; I2 = 40%). The mean rerupture rate was 2.5% (0%-6.8%) for open repair versus 1.5% (0%-4.6%) for MIS, with a nonsignificant statistical difference (OR, 1.56 [95% CI, 0.42-5.70]; P = .50; I2 = 0%). No cases of sural nerve injuries were reported in the open repair group. The mean sural nerve injury rate was 3.4% (0%-7.3%) in the MIS group, which was statistically significant (OR, 0.16 [95% CI, 0.03-0.46]; P = .02; I2 = 0%). The mean overall superficial infection rate was 6.0% (0%-18.2%) and 0.4% (0%-4.5%) for open repair and MIS, respectively, with a statistically significant difference (OR, 5.70 [95% CI, 1.80-18.02]; P < .001; I2 = 0%). The mean overall deep infection rate reported in the open repair group was 1.4% (0%-5.0%), while no deep infection was reported in the MIS group, with no statistically significant difference (OR, 3.14 [95% CI, 0.48-20.54]; P = .23; I2 = 0%). There were no significant differences between the open repair and MIS groups in the skin necrosis and dehiscence rate, adhesion rate, or keloid scar rate. The mean surgical time was 51.0 and 29.7 minutes for open repair and MIS, respectively, with a statistically significant difference (MD, 21.13 [95% CI, 15.50-26.75]; P < .001; I2 = 15%). CONCLUSION: Open Achilles tendon repair was associated with a longer surgical time, higher risk of superficial infections, and higher risk of ankle stiffness, while MIS was associated with a greater risk of temporary sural nerve palsy. The rerupture rate and functional outcomes were mostly equivalent. We found MIS to be a safe and reliable technique. However, high-quality standardized RCTs are still needed before recommending MIS as the gold standard for managing Achilles tendon ruptures.

BACKGROUND: Women have a worse prognosis after ST-segment elevation myocardial infarction (STEMI) than men. The prognostic role of thrombus burden (TB) in influencing the sex-related differences in clinical outcomes after STEMI has not been clearly investigated. OBJECTIVES: The aim of this study was to assess the sex-related differences in TB and its clinical implications in patients with STEMI. METHODS: Individual patient data from the 3 major randomized clinical trials of manual thrombus aspiration were analyzed, encompassing a total of 19,047 patients with STEMI, of whom 13,885 (76.1%) were men and 4,371 (23.9%) were women. The primary outcome of interest was 1-year cardiovascular (CV) death. The secondary outcomes of interest were recurrent myocardial infarction, heart failure, all-cause mortality, stroke, stent thrombosis (ST), and target vessel revascularization at 1 year. RESULTS: Patients with high TB (HTB) had worse 1-year outcomes compared with those presenting with low TB (adjusted HR for CV death: 1.52; 95% CI: 1.10-2.12; P = 0.01). In unadjusted analyses, female sex was associated with an increased risk for 1-year CV death regardless of TB. After adjustment, the risk for 1-year CV death was higher only in women with HTB (HR: 1.23; 95% CI: 1.18-1.28; P < 0.001), who also had an increased risk for all-cause death and ST than men. CONCLUSIONS: In patients with STEMI, angiographic evidence of HTB negatively affected prognosis. Among patients with HTB, women had an excess risk for ST, CV, and all-cause mortality than men. Further investigations are warranted to better understand the pathophysiological mechanisms leading to excess mortality in women with STEMI and HTB.

BACKGROUND: In patients with prior coronary artery bypass graft surgery (CABG), acute coronary syndrome (ACS) is not uncommon. This study investigated treatment strategy and compared clinical outcomes for native, graft and absent culprit lesions. METHODS: Single-center retrospective cohort study. From July 2010 to July 2019, 642 consecutive ACS patients with prior CABG were screened for eligibility. The primary endpoint was major adverse cardiovascular events (MACE) at 1 year, a composite of all-cause mortality, myocardial infarction, stroke and ischemia-driven revascularization. RESULTS: A total of 549 patients were included, with 215 (39.2 %) having native culprits, 256 (46.6 %) graft culprits and 78 (14.2 %) no clear culprits. Patients with native culprits were treated with native PCI in 94.0 %, re-CABG in 0.9 % and optimal medical therapy (OMT) in 5.1 %. Patients with graft culprits were treated with native PCI in 14.1 %, graft PCI in 81.2 %, re-CABG in 0.8 % and OMT in 3.9 %. All patients without a clear culprit received OMT. The cumulative incidence of 1-year MACE was 24.7 % for native vs 26.2 % for graft vs 21.8 % for absent culprits. Kaplan-Meier curves did not differ significantly. In patients with graft culprit, no significant difference in 1-year MACE was observed between native PCI and graft PCI (30.6 % vs 25.5 %, p = 0.36). CONCLUSIONS: This retrospective study shows that in ACS patients with prior CABG, MACE occurred frequently and was comparable for native, graft and absent culprits. Native PCI as treatment strategy for patients with a graft culprit was relatively common, with no significant difference in MACE as compared to graft PCI.

Background: Total ankle arthroplasty (TAA) utilization is increasing in the United States. As the incidence of this procedure grows, it is important for providers to understand the future projections for ankle arthroplasty and more importantly revision total ankle arthroplasty (rTAA). Methods: The National Inpatient Sample (USA) was queried from 2005 to 2017 for all TAA and rTAA. Poisson and linear regression analysis was performed to project annual incidence of TAA and rTAA to 2030, with subgroup analyses on septic rTAA. Results: There were 5315 TAAs performed in 2017, a 564% (P < .001) increase when compared with the TAAs performed in 2005. From 2017 to 2030, the incidence of TAAs is projected to increase from 110% to 796% (P < .001). There were 1170 rTAAs performed in 2017, a 155% (P < .001) increase when compared with rTAAs performed in 2005. There was a 256% increase in the incidence of septic rTAAs from 2005 to 2017 with a projected increase between 22% and 120% by 2030. Conclusions: The incidence of both TAAs and rTAAs is projected to significantly increase over the next decade. Given the known risk factors of TAA and rTAA, these findings reinforce the need for thoughtful consideration when selecting patients for TAA.
RESUMEN
INTRODUCTION: Intravascular ultrasound (IVUS) improves clinical outcome in patients undergoing percutaneous coronary intervention (PCI) but dedicated prospective studies assessing the safety and efficacy of IVUS guidance during primary PCI are lacking. METHODS AND ANALYSIS: The SPECTRUM study is a prospective investigator-initiated single-centre single-arm observational cohort study aiming to enrol 200 patients presenting with ST-segment elevation myocardial infarct undergoing IVUS-guided primary PCI. IVUS will be performed at baseline, postintervention and postoptimisation (if applicable), using a 40-60 MHz high-definition (HD) system. Baseline tissue characterisation includes the morphological description of culprit lesion plaque characteristics and thrombus as assessed with HD-IVUS. The primary endpoint is target vessel failure at 12 months (defined as a composite of cardiac death, target vessel myocardial infarction and clinically driven target vessel revascularisation). The secondary outcome of interest is IVUS-guided optimisation, defined as IVUS-guided additional balloon dilatation or stent placement. Other endpoints include clinical and procedural outcomes along with post-PCI IVUS findings. ETHICS AND DISSEMINATION: The protocol of this study was approved by the Ethics Committee of the Erasmus University Medical Center, Rotterdam, the Netherlands. Written informed consent is obtained from all patients. Study findings will be submitted to international peer-reviewed journals in the field of cardiovascular imaging and interventions and will be presented at international scientific meetings. TRIAL REGISTRATION NUMBER: NCT05007535.

BACKGROUND: Newer cone-beam computed tomography (CT) technology has grown in popularity for evaluation of foot and ankle pathology in the weight-bearing (WB) position. Many studies have demonstrated its benefits within the adult population, but there is a paucity of its use within the pediatric literature. The purpose of this study was to describe the indications and clinical findings of WBCT within a pediatric population. METHODS: A retrospective cohort of 68 patients (86 extremities) who underwent WBCT for a variety of conditions were compared with 48 patients (59 extremities) who underwent traditional supine nonweight-bearing (NWB) CTs. Clinical indications, demographic data, radiation doses, and cost were obtained from the medical record. WBCTs were obtained in a private outpatient orthopaedic clinic, and the conventional NWBCTs were obtained within a hospital-based system. RESULTS: The most common indications for obtaining a WBCT and NWBCT in our study were fracture, tarsal coalition, and Lisfranc injury. The average WBCT radiation dose was 0.63 mGy for patients <100 lbs and 1.1 mGy for patients >100 lbs undergoing WBCT. For NWBCTs, the average radiation dose was 7.92 mGy for patients <100 lbs and 10.37 mGy for patients greater than 100 lbs. There was a significant reduction in radiation dose for all patients who underwent WBCT (P<0.0001 vs. 0.002). The average reimbursement for NWBCTs was $505 for unilateral studies and $1451 for bilateral studies. The average reimbursement for the WBCTs was $345 for unilateral studies and $635 for bilateral studies. CONCLUSIONS: WBCT offers a new modality for studying complex foot and ankle pathoanatomy in the pediatric population at a reduced radiation exposure and reduced cost. LEVEL OF EVIDENCE: Level III-a retrospective comparative study.

PURPOSE: This study aims to provide an updated systematic review and meta-analysis of comparative studies on the outcomes and complications of locked IMNs in comparison to ORIF using plates and screws, while avoiding limitations of similar published reviews. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, two independent team members electronically searched MEDLINE (PubMed), EMBASE, Google Scholar, SCOPUS, and Cochrane databases throughout May 2021 using the following keywords with their synonyms: "Ankle fracture fixation" AND "Open reduction and internal fixation", "locked intramedullary nail", or "complications". The primary outcomes were (1) functional outcomes, (2) complications, and (3) reoperation, while the secondary outcomes were: (1) union rate, and (2) cost. INCLUSION CRITERIA: comparative studies on outcomes and complications of plate open reduction and internal fixation (ORIF) vs. locked intramedullary nailing (IMN) of ankle fractures reporting at least one of the following parameters: functional outcomes, complications (infection, dehiscence, reoperation etc.), union, and cost. Studies reporting on non-locked intramedullary fibular nails were also excluded. RESULTS: After the removal of duplicates, a total of 1461 studies were identified. After screening those records, 63 studies remained for full-text assessment. Out of those, four comparative studies with a total of 262 ankle fractures met the inclusion criteria for this meta-analysis. The mean 12 months postoperative Olerud and Molander Ankle Scores (OMAS) were reported by two studies, with a statistically significant difference in favor of IMNs (MD= 6.72, CI: 3.77-9.67, p<0.001, I2= 94%). In the ORIF group, the overall complication rate was 39/134 (29.1%) vs. 10/128 (7.8%) in the IMN group, with a statistically significant difference in favor of the IMN group (RR=3.23, CI:1.71-6.11, p<0.001, I2=34%). In the ORIF group, the overall infection rate was 11/134 (8.2%), while there were no infections in the IMN group, with a statistically significant difference in favor of the IMN group (RR=8.05, CI:1.51-42.82, p=0.01, I2=0%). In the ORIF group, the overall reoperation rate was 10/134 (7.5%) while the overall reoperation rate was 6/128 (4.7%) in the IMN group, with no statistically significant difference between groups (RR=1.49, CI: 0.60-3.70, p = 0.39, I2=0%). CONCLUSION: Locked intramedullary nail fixation of distal fibula fractures could provide superior functional outcomes and lower complication rates in comparison to open reduction and plate fixation. Despite the high incidence of ankle fractures, the number of high-quality comparative studies remains limited in literature, especially on newer locked fibular nails, and large multicentric clinical trials are required before recommending locked IMNs as the new standard of care in distal fibula fractures.

BACKGROUND: Intravascular ultrasound (IVUS) can overcome the intrinsic limitations of coronary angiography for lesion assessment and stenting. IVUS improves outcomes of patients presenting with stable or complex coronary artery disease, but dedicated data on the impact of IVUS-guided percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) remains scarce. METHODS: We systematically searched Embase, MEDLINE, Web of Science Core Collection, Cochrane Central Register of Controlled Trials and Google Scholar for studies that compared clinical outcomes for IVUS- versus angio-guided PCI in patients with AMI. The primary endpoint was all-cause mortality and the secondary endpoint major adverse cardiovascular events (MACE). Mantel-Haenszel random-effects model was used to calculate pooled risk ratios (RR) with 95% confidence intervals (CI). RESULTS: Nine studies (8 observational, 1 RCT) with a total of 838.902 patients (796.953 angio-guided PCI, 41.949 IVUS-guided PCI) were included. In patients with AMI, IVUS-guided PCI was associated with a significantly lower risk of all-cause mortality (pooled RR: 0.70; 95% CI, 0.59-0.82; p < 0.01), MACE (pooled RR: 0.86; 95% CI, 0.74-0.99; p = 0.04) and target vessel revascularization (TVR) (pooled RR: 0.83; 95% CI, 0.73-0.95; p < 0.01). In the subset of patients presenting with ST-segment elevation, IVUS-guided PCI remained associated with a reduced risk for both all-cause mortality (pooled RR: 0.79; 95% CI, 0.66-0.95, p = 0.01) and MACE (pooled RR: 0.86; 95% CI, 0.74-0.99, p = 0.04). CONCLUSIONS: This is the first systematic review and meta-analysis comparing IVUS- versus angio-guided PCI in patients with AMI, showing a beneficial effect of IVUS-guided PCI on all-cause mortality, MACE and TVR. Results of ongoing dedicated prospective studies are needed to confirm these findings.

PURPOSE: This study aims to report on the safety and donor site morbidity of the distal lower extremity (calcaneal, proximal, and distal tibial) cancellous bone autografts. We summarized the findings in a comprehensive infographic illustration. We are unaware of any similar meta-analyses to date. METHODS: Following the PRISMA guidelines, two independent investigators searched MEDLINE (PubMed), EMBASE, SCOPUS, Google Scholar, and Cochrane databases in December 2020 using the following keywords and their synonyms: ("bone graft", "donor site morbidity", "calcaneal graft", "proximal tibia graft", and "distal tibia graft"). Besides, the reference lists from previous review articles were searched manually for eligible studies. The primary outcomes of interest were (1) chronic pain, (2) fracture, and (3) infection, whereas the secondary outcomes were (1) neurological complications, (2) sensory disturbance and hypertrophic scars, (3) other complications such as shoe-wear difficulties and gait disturbance. Inclusion criteria were: studies on complications and adverse events of lower extremity bone autografts (calcaneal, proximal tibial, and distal tibial bone autografts) reporting at least one of the desired outcomes. Studies not reporting any of the outcomes of interest or if the full text is not available in English were excluded. Studies reporting on bone marrow aspirate or autografts for non-orthopedic indications were also excluded. RESULTS: After the removal of duplicates, a total of 5981 studies were identified. After screening those records, 85 studies remained for full-text assessment. Out of those, 15 studies qualified for the meta-analysis with a total of 2296 bone grafts. Out of those grafts, 1557(67.8%) were calcaneal grafts, 625 (27.2%) were proximal tibial grafts, and 114 (5%) were distal tibial grafts. In calcaneal bone grafts, there were 28 cases of chronic pain [1.97%, CI:1.10-2.50%, I2 = 66%], 5 fractures [0.32%, CI: 0.10-0.60%,I2 = 0%], 20 sural neuritis [1.28%, CI:0.70-1.80%, I2 = 0%), and no wound infections. In proximal tibial grafts there were 13 cases of chronic pain [2.08%, CI: 1.01-3.2%, I2 = 34.5%], 1 fracture [0.16%, CI:0.10-0.50%, I2 = 0%], and 3 superficial wound infections [0.48%, CI: 0.10-1.01, I2 = 0%]. In the distal tibial grafts there were no cases of chronic pain or wound infections, 1 fracture [0.90%, CI: 0.80-2.6%, I2 = 0%], and 5 saphenous neuritis [4.5%, CI: 0.70-8.40%, I2 = 65%]. CONCLUSION: Calcaneal, distal tibial, and proximal tibial bone autografts are safe with a low rate of overall and major complications. We report an overall complication rate of 6.8%, which is less than half of that previously reported for iliac crest grafts. The authors recommend using distal lower extremity grafts for foot and ankle primary surgeries instead of iliac crest grafts when indicated. Clinical trials with a large sample size are required.

Background: The results supporting Cartiva, a synthetic cartilage implant (Wright Medical) in hallux rigidus have come from limited institutions creating observational bias. Complications experienced in community centers are not routinely included in the published literature. To look at a broader range of potential complications, we reviewed the United States Food and Drug Administration's (FDA) voluntary device database and compared that data with published literature. Methods: The Manufacturer and User Facility Device Experience (MAUDE) database of the FDA was retrospectively reviewed between July 2016 and October 2019 using the product code: PNW, assigned for Cartiva. Results: A total of 49 events have been reported and implant subsidence was the most common with 16 reports. Others include fragmentation (9), infection (4), bone erosion (3), foreign body reaction (1) and unspecified (16). Thirty-five events mentioned further surgeries at a mean interval of 4.75 months. Conclusions: The analysis of the MAUDE database disclosed certain device-related dysfunctions that have been underreported in the published literature. Because of the voluntary nature of reporting, the true incidence of each complication is unknown with this data representing a baseline. The MAUDE database could be further strengthened by a more robust reporting mechanism or mandatory reporting of device-related complications.Levels of Evidence: Level IV: Case series from large database analysis.

INTRODUCTION: There is paucity of data on the outcomes of hospitalization for bicuspid aortic valve (BAV)-related aortopathies. METHODS: We queried the NIS database (2012-2016) for hospitalizations for elective thoracic aortic repair or acute aortic syndrome (AAS) among those with BAV versus trileaflet aortic valve (TAV). RESULTS: Our analysis yielded 38,010 hospitalizations for elective aortic repair, of whom 34.4% had BAV, as well as 81,875 hospitalizations for thoracic AAS, of whom 1.1% had BAV. Hospitalizations for BAV were younger and had fewer comorbidities compared with their TAV counterparts. The number of hospitalizations for BAV during the observational period was unchanged. After propensity matching, elective aortic repair for BAV was associated with lower mortality (0.5% versus 1.7%, odds ratio = 0.28; 95% CI 1.5-0.50, p < 0.001), use of mechanical circulatory support, acute stroke, and shorter length of hospital stay compared with TAV. After propensity matching, AAS among those with BAV had a greater incidence of bleeding events, blood transfusion, cardiac tamponade, ventricular arrhythmias, and a longer length of hospital stay compared with TAV. Among those with BAV, predictors of lower mortality if undergoing elective aortic repair included larger hospitals and teaching hospitals. Predictors of higher mortality in patients with AAS included heart failure, chronic kidney disease, and coronary artery disease. CONCLUSION: Data from a national database showed no change in the number of hospitalizations for BAV-related aortopathy, with relatively lower incidence of AAS. Compared with TAV, elective aortic repair for BAV is associated with lower mortality, while BAV-related AAS is associated with higher in-hospital complications.
RESUMEN
BACKGROUND: Nearly 20% of acute ankle sprains progress to chronic lateral ankle instability that requires surgical intervention. In recent years, there has been a growing interest in arthroscopic Broström techniques as an alternative to open surgery. PURPOSE: To review the most up-to-date evidence comparing the outcomes of open and arthroscopic Broström procedures for chronic lateral ankle instability. STUDY DESIGN: Systematic review; Level of evidence, 3. METHODS: This review was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Relevant comparative studies in English up to May 2020 were identified. The primary outcomes were (1) functional scores (Karlsson Ankle Function Score and American Orthopaedic Foot & Ankle Society [AOFAS] score) and (2) the 10-point visual analog scale (VAS) score for pain. The secondary outcomes were differences in (1) postoperative anterior drawer and talar tilt, (2) surgical time and complication rate, and (3) time to return to sports and weightbearing. RESULTS: A total of 408 patients in 8 studies met the inclusion criteria. Of these, 193 (47.3%) patients underwent open surgery, while 215 (52.7%) patients underwent arthroscopic surgery. There were significant differences between the open and arthroscopic repair groups in mean 6-month AOFAS scores (82.4 vs 92.25, respectively; mean difference [MD], 11.36; 95% CI, 0.14-2.56; I 2 = 90%; P = .03), 1-year AOFAS scores (80.05 vs 88.6; MD, -11.96; 95% CI, -21.26 to -2.76; I 2 = 82%; P = .01), 6-month VAS scores (1.7 vs 1.4; MD, -0.38; 95% CI, -0.54 to -0.21; I 2 = 78%; P < .001), and 1-year VAS scores (2.05 vs 1.45; MD, 0.31; 95% CI, 0.09-0.54; I 2 = 0%; P < .001). The mean time to weightbearing was 14.25 and 9.0 weeks in the open and arthroscopic repair groups, respectively (MD, 1.89; 95% CI, 1.24-2.54; I 2 = 99%; P < .001). There were no statistically significant differences in the remaining outcomes evaluated. CONCLUSION: While technically more demanding, arthroscopic Broström was superior to open Broström-Gould surgery in postoperative AOFAS scores, VAS pain scores, and time to return to weightbearing. The operative time, complication rate, talar tilt, and anterior drawer tests were excellent and statistically comparable. Long-term clinical trials are required before recommending arthroscopic Broström as the new gold standard.
RESUMEN
PURPOSE: This meta-analysis aims to provide updated evidence on the success rate, return to play (RTP) rate, time to RTP, and complications of operatively and conservatively managed navicular stress fractures (NSFs) as well as delays in diagnosis while avoiding limitations of previous similar studies. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, two independent team members electronically searched MEDLINE (PubMed), EMBASE, Google Scholar, SCOPUS, and Cochrane databases throughout February 2021 using the following keywords with their synonyms: "Navicular stress fracture," "return to play," and "athletes." The primary outcomes were (1) management success rate, (2) RTP rate, and (3) time to RTP. The secondary outcomes were (1) non-union, (2) time to diagnosis, (3) refracture, and (4) other complications. Inclusion criteria were clinical studies on NSFs reporting at least one of the desirable outcomes. Studies not reporting any of the outcomes of interest or the full text was not available in English, German, French, or Arabic were excluded. Case reports, case series with less than ten cases, and studies reporting exclusively on navicular non-union management were also excluded. The Newcastle-Ottawa scale was used for quality assessment while Review Manager (RevMan) Version 5.4 was used for the risk of bias assessment. Data were presented by type of treatment (surgical or conservative). If enough studies were present that were clinically and statistically homogeneous and data on them adequately reported, a meta-analysis was performed using a fixed-effects model. In case of statistical heterogeneity, a random-effects model was used. If meta-analysis was not possible, results were reported in a descriptive fashion. The need to explore for statistical heterogeneity was determined by an I2 greater than 40%. RESULTS: Eleven studies met the inclusion criteria with a total of 315 NSF. Out of those, 307 (97.46%) NSFs were in athletes. One hundred eight (34.29%) NSFs were managed operatively, while 207 (65.71%) NSFs were managed conservatively. Successful outcomes were reported in 104/108 (96.30%) NSF treated operatively with a mean success rate of 97.9% (CI: 95.4-100%, I2 = 0%). Successful outcomes were reported in 149/207 (71.98%) NSF treated conservatively, with a mean success rate of 78.1% (CI: 66.6-89.6%, I2 = 84.93%). Successful outcome differences were found to be significant in favor of operative management (OR = 5.52, CI: 1.74-17.48, p = 0.004, I2 = 4.6%). RTP was noted in 97/98 (98.98%) NSF treated operatively and in 152/207 (73.43%) NSF treated conservatively, with no significant difference between operative and conservative management (OR = 2.789, CI: 0.80-9.67, p = 0.142, I2 = 0%). The pooled mean time to RTP in NSF treated operatively was 4.17 months (CI: 3.06-5.28, I2 = 92.88%), while NSF treated conservatively returned to play at 4.67 months (CI: 0.97-8.37, I2 = 99.46%) postoperatively, with no significant difference between operative and conservative management (SMD = - 0.397, CI: - 1.869-1.075, p = 0.60, I2 = 92.24). The pooled mean duration of symptoms before diagnosis was 9.862 (3.3-123.6) months (CI: 6.45-13.28, I2 = 94.92%), reported in ten studies. Twenty (23.53%) refractures were reported after conservative management of 85 NSFs, while one (1.28%) refracture was reported after operative management of 78 NSFs, with a significant difference in favor of operative management (OR = 0.083, CI: 0.007-0.973, p = 0.047, I2 = 38.78%). CONCLUSION: Operative management of NSF provides a higher success rate, a lower refracture rate, and a lower non-union rate as compared to other non-operative management options. While not significant, there is a notable trend towards superior RTP rates and time to RTP following operative management. Therefore, we recommend operative fixation for all NSFs type I through III in athletes. Athletes continue to exhibit an alarmingly long duration of symptoms before diagnosis is made; a high index of suspicion must be maintained, therefore, and adjunct CT imaging is strongly recommended in the case of any work-up. Unfortunately, the published literature on NSFs remains of lower level of evidence and high-quality studies are needed.

Hallux rigidus is the most common arthritic pathology of the foot. This review article discusses the pathophysiology and common clinical presentation of hallux rigidus. Furthermore, we discuss multiple classification systems that categorize the arthritic process and guide management. Surgical interventions include cheilectomy, Moberg osteotomy, synthetic cartilage implants, interpositional arthroplasty, and arthrodesis. The common complications are reviewed, and the rates of these complications highlighted. Surgical options for hallux rigidus globally have successful outcomes with low rates of complications when done on appropriate patients.

BACKGROUND: Although studies are available on high-energy Lisfranc injuries, the evidence for increasingly reported low-energy Lisfranc injuries in active individuals, including athletes and military personnel, remains scarce and mostly retrospective. PURPOSE: This meta-analysis aimed to review the return-to-play (RTP) and return-to-duty (RTD) rates with regard to the anatomic type and the management of low-energy Lisfranc injuries in a high-demand, active population. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched the MEDLINE (PubMed), EMBASE, Google Scholar, and Cochrane databases through June 2019 to identify studies on low-energy Lisfranc injuries in athletes and military personnel. The primary outcomes were RTP/RTD rates and time to RTP/RTD, and the secondary outcomes were time missed from practice, games missed, time to full recovery, midfoot arthritis rate, and reoperation rate. RESULTS: Overall, 15 studies (N = 441 patients) were included in the meta-analysis. Of these, 6 studies were of level 3 evidence, 8 studies were level 4 (case series), and 1 study was level 5. Of the 441 subjects, 380 (86.17%) were able to RTP and RTD. There was no statistically significant difference in RTP rates for operative versus nonoperative treatment, ORIF versus PA, or bony versus ligamentous injuries. The mean time missed from practice/duty for operative versus nonoperative treatment was 58.02 days (95% CI, 13.6-102.4 days; I 2 = 98.03%) and 116.4 days (95% CI, 62.4-170.4 days; I 2 = 99.45%), respectively. The mean time missed from practice/duty for bony versus ligamentous injury was 98.9 days (95% CI, 6.1-191.7 days; I 2 = 99.82%) and 76.5 days (95% CI, 37.9-115.02 days; I 2 = 99.83%), respectively, with no statistically significant differences (standardized mean difference = 3.62 days [95% CI: -5.7 to 13 days]; I 2 = 83.17%). CONCLUSION: This review indicated an overall excellent RTP/RTD rate for low-energy Lisfranc injuries in high-demand individuals. The time missed from athletic participation/military duty was not affected by injury treatment type, the bony versus ligamentous nature of the injury, or athlete player position. However, the low evidence levels and significant heterogeneity of the included studies precludes making conclusions regarding length of time missed or optimal management. Higher-quality studies on low-energy Lisfranc injuries are needed.
