Primary versus conversion reverse total shoulder arthroplasty for complex proximal humeral fractures in elderly patients: a retrospective comparative study.

BACKGROUND: The purpose of this study was to compare clinical, implant-related, and patient-reported outcomes of shoulders undergoing conversion to reverse total shoulder arthroplasty (rTSA) following previous open reduction-internal fixation vs. shoulders undergoing rTSA as a primary treatment modality for acute proximal humeral fractures (PHFs) in patients aged ≥65 years. METHODS: We performed a retrospective analysis of a prospectively collected cohort of patients who underwent primary rTSA for PHFs vs. a cohort who underwent conversion arthroplasty with rTSA following fracture repair between 2009 and 2020. Outcomes were assessed preoperatively and at latest follow-up. Demographic characteristics and outcomes were analyzed between cohorts using conventional statistics, as well as stratification by minimal clinically important difference and substantial clinical benefit thresholds where applicable. RESULTS: In total, 406 patients met the study criteria, of whom 322 underwent primary rTSA for PHF and 84 underwent conversion rTSA after failed PHF open reduction-internal fixation. The conversion rTSA cohort was, on average, 7 years younger than the primary rTSA cohort (65 ± 10 years vs. 72 ± 9 years, P < .001). The follow-up periods were similar between the cohorts, with an average of 47.1 months (range, 24-138 months). The percentages of Neer 3-part (41.9% vs. 45.2%) and 4-part (49.1% vs. 46.4%) PHFs were similar (P > .99). The primary rTSA cohort achieved higher forward elevation, external rotation, and patient-reported outcome measurements including Simple Shoulder Test, American Shoulder and Elbow Surgeons, University of California-Los Angeles, Constant, Shoulder Arthroplasty Smart, and Shoulder Pain and Disability Index scores at a minimum of 24 months postoperatively (P < .05 for all). Patient satisfaction was higher in the primary rTSA group than in the conversion rTSA cohort (P = .002). Patient-reported outcome measures uniformly favored the primary rTSA cohort, rising to the level of statistical significance for forward elevation, American Shoulder and Elbow Surgeons score, and Shoulder Pain and Disability Index score (P < .05) relative to substantial clinical benefit. The adverse event rate and revision rate in the conversion rTSA cohort were higher than those in the primary rTSA cohort (26.2% vs. 2.5% [P < .001] and 8.3% vs. 1.6% [P = .001], respectively). At 10 years postoperatively, the revision-free implant survival rate was significantly lower in the conversion cohort compared with the primary cohort (66% vs. 94%, P = .012). Finally, the hazard ratio of revision was 3.69 in the conversion rTSA cohort compared with only 1.0 in the primary rTSA cohort. CONCLUSION: This study demonstrates that elderly patients who undergo rTSA as a conversion procedure following previous osteosynthesis do not fare as well as those treated with rTSA for acute displaced PHFs. Conversion rTSA patients report lower patient satisfaction and have significantly restricted range of shoulder motion, a higher risk of complications, a higher risk of revision, poorer patient-reported outcomes, and a shorter implant survival rate at 10 years compared with patients undergoing acute rTSA.

Successful tricuspid valve repair and right atrial mass excision for calcified thrombus causing severe tricuspid regurgitation and near-occlusion of inferior vena cava.

BACKGROUND: Calcified right atrial thrombus is rare and commonly occurs secondary to atrial fibrillation and long-term central venous catheterization which present risk for embolization. Treatment typically involves anticoagulation and antiplatelet therapy but rarely surgical excision can be performed, especially in patients with venous obstruction or concomitant valvular dysfunction. CASE PRESENTATION: We present the case of a 69 year old symptomatic female with a history of atrial fibrillation and long-term venous catheterization found to have a large calcified right atrial thrombus causing inferior vena cava obstruction and severe tricuspid regurgitation. Patient underwent full median sternotomy with ascending arterial cannulation with superior vena cava and femoral venous cannulation. Intraoperatively, extensive right atrial calcified thrombus was found extending into the inferior vena cava and involving the septal portion of the tricuspid valve annulus causing regurgitation. The calcified thrombus was removed which resolved the inferior vena cava obstruction and the tricuspid valve was repaired by transecting septal leaflet chordae, commissuroplasty, and ring annuloplasty. Postoperative course was uncomplicated and pathology confirmed a calcified right atrial thrombus. At 6 month follow up, the patient was asymptomatic with echocardiogram showing no inferior vena cava stenosis and trivial tricuspid regurgitation. CONCLUSIONS: Surgical excision of calcified right atrial thrombus is rare and is often indicated for symptomatic patients with extensive involvement causing venous inflow obstruction or valvular dysfunction. Sufficient preoperative imaging and a multi-disciplinary approach are essential for accurate diagnosis to guide targeted treatment. When the tricuspid valve is involved, repair is preferred over replacement in this patient population given their propensity for calcification and thrombus formation which may result in an increased risk of early bioprosthetic valve degeneration or mechanical valve thrombosis.

Effects of Sociodemographic Factors on Access to and Outcomes in Congenital Heart Disease in the United States.

Congenital heart defects (CHDs) are complex conditions affecting the heart and/or great vessels that are present at birth. These defects occur in approximately 9 in every 1000 live births. From diagnosis to intervention, care has dramatically improved over the last several decades. Patients with CHDs are now living well into adulthood. However, there are factors that have been associated with poor outcomes across the lifespan of these patients. These factors include sociodemographic and socioeconomic positions. This commentary examined the disparities and solutions within the evolution of CHD care in the United States.

Frequent Sural Nerve Injury with Posterior Approach for Ankle Fracture Fixation.

INTRODUCTION: The purpose of this study was to report the incidence of iatrogenic sural nerve injury in a large, consecutive sample of surgically managed ankle fractures and to identify factors associated with sural nerve injury and subsequent recovery. We hypothesize that a direct posterior approach may be associated with higher risk of iatrogenic sural nerve injury. METHODS: A retrospective cohort study of 265 skeletally mature patients who sustained ankle fractures over a 2-year period was done. All were treated with open reduction and internal fixation of fractured malleoli. Patient, injury, and treatment features were documented. The presence (n = 26, 9.8%) of sural nerve injury and recovery of sural nerve function were noted. RESULTS: All 26 sural nerve injuries were iatrogenic, occurring postoperatively after open reduction and internal fixation. Patients who sustained sural nerve injuries had more ankle fractures secondary to motor vehicle collisions (23.1% versus 9.2%), more associated trimalleolar fractures (69.2% versus 33.9%), and more Orthopaedic Trauma Association/AO 44B3 fractures (57.7% versus 25.1%), all P < 0.05. A posterior approach to the posterior malleolus through the prone position was used in 20.4% of patients. All 26 of the sural nerve injuries (100%) occurred when the patient was placed prone for a posterior approach, P < 0.001. Therefore, 26 of the 54 patients (48%) treated with a posterior approach sustained an iatrogenic sural nerve injury. 62% of patients had full recovery of sural nerve function with no residual numbness, and patients with nerve recovery had fewer associated fracture-dislocations (23.1% versus 100%, P = 0.003). CONCLUSIONS: A posterior approach for posterior malleolus fixation was associated with a 48% iatrogenic sural nerve injury rate, with 62% recovering full function within 6 months of injury. Morbidity of this approach should be considered, and surgeons should be cautious with nerve handling. LEVEL OF EVIDENCE: Level III, Therapeutic.

Predictors and outcomes of discharge to long-term acute care facilities after cardiac surgery.

OBJECTIVE: An increasing number of patients with significant comorbidities present for complex cardiac surgery, with a subgroup requiring discharge to long-term acute care facilities. We aim to examine predictors and mortality after discharge to a long-term acute care facility. METHODS: From January 1, 2015, to April 30, 2021, all adult cardiac surgeries were queried and patients discharged to long-term acute care facilities were identified. Baseline characteristics, procedures, and in-hospital complications were compared between long-term acute care facility and non-long-term acute care facility discharges. Random forest analysis was conducted to establish predictors of discharge to long-term acute care facilities. Kaplan-Meier survival analysis was used to determine probability of survival over 7 years. Multivariate regression modeling was used to establish predictors of death after long-term acute care facility discharge. RESULTS: Of 29,884 patients undergoing cardiac surgery, 324 (1.1%) were discharged to a long-term acute care facility. The long-term acute care facility group had higher rates of urgent/emergency operation (54% vs 23%; 10% vs 3%, P < .001) and longer mean cardiopulmonary bypass (167 vs 110 minutes, P < .001). By random forest analysis, emergency/urgent status, longer cardiopulmonary bypass duration, redo surgery, endocarditis, and history of dialysis were the most predictive of discharge to a long-term acute care facility. Although the non-long-term acute care facility group demonstrated greater than 95% survival at 6 months, Kaplan-Meier survival analysis showed 28% 6-month mortality in the long-term acute care facility cohort. Random forest analysis demonstrated that chronic lung disease and postoperative respiratory complications were significant predictors of death at 6 months after discharge to a long-term acute care facility. CONCLUSIONS: Patients with chronic lung and kidney disease undergoing prolonged procedures are at higher risk to be discharged to long-term acute care facilities after surgery with worse survival. Efforts to minimize postoperative respiratory complications may reduce mortality after discharge to long-term acute care facilities.

Comparing Outcomes After Referral to Physical Therapy for Patients With Glenohumeral Osteoarthritis Based on the Radiographic Osteoarthritis Severity: A Retrospective Analysis.

Introduction Glenohumeral osteoarthritis (GHOA) is a common cause of musculoskeletal pain (MSP) that can frequently lead to pain and functional disability in patients throughout the world. GHOA can be managed with conservative or surgical interventions, although conservative interventions, such as physical therapy (PT), are generally first-line interventions depending on the severity of GHOA. The purpose of this retrospective analysis was to examine how conventional PT impacts outcomes for patients with GHOA based on the severity of radiographic GHOA findings. Methods This study is a retrospective chart review of patients who were referred to PT for MSP and received PT in the outpatient setting between 2016 and 2022. Inclusion criteria were patients who received PT in the outpatient setting, received PT for MSP, had shoulder radiograph imaging within two years of initial PT evaluation, had more than one PT visit (i.e. attended a follow-up session after initial evaluation), and did not have a history of shoulder surgery. Primary outcome measures were pain, abduction active range-of-motion (AROM), and disability via the quick disabilities of the arm, shoulder, and hand (DASH). Patients were divided into the No GHOA group (n=104), Mild GHOA group (n=61), and Moderate/Severe GHOA group (n=55) based on the radiographic GHOA severity. Results All included patients (n=220) had a mean age of 62.2 ± 12.4 years old with a mean number of PT visits of 7.8 ± 4.5 visits. There was initially a significant difference in the magnitude of pain improvement between the three groups based on radiographic severity of GHOA (Kruskal-Wallis H=6.038; p=0.049); however, post hoc testing revealed no significant difference between any of the three groups for pain improvement (p=0.061 to p=1.000). There was also no significant difference in the magnitude of abduction AROM improvement between the three groups based on the radiographic severity of GHOA (Kruskal-Wallis H=2.887; p=0.236). Finally, there was no significant difference in the magnitude of disability improvement via the Quick DASH between the three groups based on the radiographic severity of GHOA (Kruskal-Wallis H=0.156; p=0.925). Conclusion Patients with GHOA referred to PT experience small but statistically significant short-term improvements in pain, abduction AROM, and disability regardless of GHOA radiographic severity. There is no significant association between the magnitude of clinical improvement and the severity of radiographic GHOA. However, despite statistically significant improvements in pain, only patients with mild GHOA experienced clinically significant improvements in pain. Patients with GHOA, regardless of severity, may or may not experience clinically significant improvements in disability after PT.

Clinical Outcomes Associated With the Addition of a Physical Therapist Assistant to a Rehabilitation Team When Treating Musculoskeletal Shoulder Pain in the Outpatient Setting: A Retrospective Cohort Study.

Introduction Musculoskeletal shoulder pain (MSP) is a common condition frequently treated in an outpatient setting by a physical therapy rehabilitation team. Treatment teams can consist of physical therapists (PTs) with or without physical therapist assistants (PTAs). It is currently unknown how different physical therapy team compositions can impact patient outcomes in the outpatient setting. The purpose of this study is to examine how the addition of PTAs to a physical therapy treatment team would impact clinical outcomes when treating patients with MSP in the outpatient setting. Methods This study is a retrospective cohort analysis comparing clinical outcomes for pain, active range of motion (AROM), and disability for patients with MSP when treated by physical therapy treatment teams with or without the presence of PTAs. Inclusion criteria were patients treated for MSP in an outpatient physical therapy clinic without a history of shoulder surgery. Depending on the rehabilitation team composition, patients were divided into a PT-only group or a PTA group. Results Total patients (n = 238) had a mean age of 62.6 ± 12.6 years (median: 64 years) with a mean total number of physical therapy visits of 7.8 ± 4.9 visits (median: 7.0 visits). Of the entire cohort, the PT-only group had 100 patients and the PTA group had 138 patients. There was no significant difference in the magnitude of pain improvement (mean: 1.5 versus 1.9 points, p = 0.177), the magnitude of abduction AROM improvement (mean: 17.6 versus 13.9 degrees, p = 0.173), and the magnitude of disability improvement (mean: 18.9 versus 13.4 percentage points, p = 0.221) between the PT-only group and the PTA group. However, the PT-only group had significantly fewer total visits as compared to the PTA group (6.7 versus 8.6 visits, p < 0.001). Conclusion The addition of PTAs to a rehabilitation team when treating patients with MSP in the outpatient setting does not appear to adversely impact pain, AROM, or disability outcomes. However, patients treated only by PTs had significantly less visits with similar outcomes. More research is needed to determine the interplay between cost, healthcare utilization, and patient outcomes to maximize quality care.

Parsonage Turner syndrome after cervical trauma and COVID-19 infection: a case report and review of the literature.

Background: Parsonage Turner syndrome is an uncommon condition characterized by acute onset shoulder pain, followed by neurologic deficits such as weakness and paresthesia. It is a condition that is thought to be immune-mediated, and triggered by several recognized factors such as trauma, surgery, infections, and immunizations. Upper extremity Parsonage Turner syndrome may affect any distribution of the brachial plexus and most commonly presents unilaterally. Clinical history and examination are the basis of diagnosis, although electrodiagnostic studies may be important for confirmation. Magnetic resonance and ultrasonographic studies have also been effectively used in the diagnosis of Parsonage Turner syndrome. The case herein presents a patient with multiple possible triggers of Parsonage Turner syndrome. Case Description: We present a case of 62-year-old Caucasian male with bilateral radicular pain and weakness in the upper extremities after cervical spine surgery for a fracture in a patient that was infected with COVID-19. The patient underwent electrodiagnostic testing, as well as ultrasonographic studies that demonstrated Parsonage Turner syndrome. A literature review on Parsonage Turner syndrome associated with trauma, surgery and COVID-19 was also performed. Conclusions: Most cases of Parsonage Turner syndrome have a known associated risk factor. The patient in this report is unique in that they had several known risk factors for Parsonage Turner syndrome simultaneously. For timely and accurate diagnosis, it is important to consider the potential triggers of Parsonage Turner syndrome including trauma, surgery and viral illnesses such as COVID-19.

Association of Chronic Kidney Disease and Complications Following Acute Torsional Ankle Fracture.

BACKGROUND: Although chronic kidney disease (CKD) has been associated with poor outcomes following traumatic fractures, there is a scarcity of literature describing the effect on outcomes of ankle fractures. We will examine the impact of CKD on clinical outcomes following torsional ankle fracture, including complications and unplanned surgical procedures. METHODS: A retrospective review of 1981 adult patients with torsional ankle fractures treated at a level 1 trauma center was performed to identify patients with CKD based on glomerular filtration rate. Demographic, injury, and treatment-related characteristics were collected. Outcomes included any unplanned procedure: implant removal, debridement, revision, arthrodesis, and amputation; in addition to complications of superficial infection, deep infection, and implant irritation. Patients with CKD were matched with patients without CKD by propensity score matching. Univariate comparisons between groups were conducted using chi-square and Mann-Whitney U tests. RESULTS: 136 patients (68 with CKD and 68 without CKD) were analyzed. Of the 68 patients with CKD, the mean stage of disease was 3.7 with 24% on dialysis for a mean length of 4.1 years. Patients without CKD were more likely to undergo primary ORIF (100% vs 54%, P < .001). Thirty-five percent of patients with CKD had surgical complications vs 19% in the cohort without (P = .07). Patients with open fractures, dislocation, and chronic kidney disease were, respectively, 5.19, 3.77, and 3.91 times more likely to have any complication (P = .02, P = .05, P = .05). Patients with CKD were more likely to undergo unplanned arthrodesis (P = .01). Only dislocation was an independent predictor for unplanned procedure (odds ratio = 5.08, P = .026). CONCLUSION: Following torsional ankle fracture, CKD is associated with increased likelihood of having a complication or an unplanned arthrodesis. Open fractures and dislocation at time of injury are also associated with complications. Our findings encourage caution about surgical treatment of ankle fractures in patients with CKD. LEVEL OF EVIDENCE: Level III, retrospective, comparative, prognostic.

Outcomes in surgical treatment for tandem spinal stenosis: systematic literature review.

BACKGROUND CONTEXT: Tandem spinal stenosis (TSS) refers to a narrowing of the spinal canal in distinct, noncontiguous regions. TSS most commonly occurs in the cervical and lumbar regions. Decompressive surgery is indicated for those with cervical myelopathy or persistent symptoms from lumbar stenosis despite conservative management. Surgical management typically involves staged procedures, with cervical decompression taking precedence in most cases, followed by lumbar decompression at a later time. However, several studies have shown favorable outcomes in simultaneous decompression. PURPOSE: The aim of this study is to provide a literature review and compare surgical outcomes in patients undergoing staged vs simultaneous surgery for TSS. STUDY DESIGN/SETTING: Systematic literature review. METHODS: A systematic review using PRISMA guidelines to identify original research articles for tandem spinal stenosis. PubMed, Cochrane, Ovid, Scopus, and Web of Science were used for electronic literature search. Original articles from 2005 to 2021 with more than eight adult patients treated surgically for cervical and lumbar TSS in staged or simultaneous procedures were included. Articles including pediatric patients, primarily thoracic stenosis, stenosis secondary to neoplasm or infectious disease, minimally invasive surgery, and non-English language were excluded. Demographic, perioperative, complications, functional outcome, and neurologic outcome data including mJOA (modified Japanese Orthopaedic Association), Nurick grade (NG), and ODI (Oswestry disability index), were extracted and summarized. RESULTS: A total of 667 articles were initially identified. After preliminary screening, 21 articles underwent full-text screening. Ten articles met our inclusion criteria. A total of 831 patients were included, 571 (68%) of them underwent staged procedures, and 260 (32%) underwent simultaneous procedures for TSS. Mean follow-ups ranged from 12 to 85 months. There was no difference in estimated blood loss (EBL) between staged and simultaneous groups (p=.639). Simultaneous surgeries had shorter surgical time than staged surgeries (p<.001). Mean changes in mJOA, NG, and ODI was comparable between staged and simultaneous groups. Complications were similar between the groups. There were more major complications reported in simultaneous operations, although this was not statistically significant (p=.301). CONCLUSION: Staged and simultaneous surgery for TSS have comparable perioperative, functional, and neurologic outcomes, as well as complication rates. Careful selection of candidates for simultaneous surgery may reduce the length of stay and consolidate rehabilitation, thereby reducing hospital-associated costs.
