5-Factor Modified Frailty Index as a Predictor of Outcomes After Hemiarthroplasty or Total Hip Arthroplasty for Femoral Neck Fracture.

INTRODUCTION: Although the 5-factor modified frailty index (mFI-5) has been shown to be an independent predictor of complications after primary total hip arthroplasty (THA), its predictive value has not been evaluated in the setting of hip fracture. We therefore assessed the utility of mFI-5 score as an independent predictor of morbidity and mortality in patients who underwent THA or hemiarthroplasty for femoral neck fracture. METHODS: The American College of Surgeons National Surgical Quality Improvement database was queried for all patients with femoral neck fractures treated with THA or hemiarthroplasty between 2006 and 2020. A multivariate logistic regression analysis was done using mFI-5 as a predictor while controlling for baseline demographic and clinical variables. RESULTS: In total, 45,185 patients (hemiarthroplasty: 37,645; THA: 7,540) were identified. For hemiarthroplasty patients, the mFI-5 strongly predicted risk of any complication (OR, 1.1; 95% CI, 1.1 to 1.2; P < 0.001), bleeding (OR, 1.2; 95% CI, 1.1 to 1.3; P < 0.001), and readmission (OR, 1.2; 95% CI, 1.1 to 1.3; P < 0.001). For THA patients, the mFI-5 was a strong predictor of any complication (OR, 1.2; 95% CI, 1.0 to 1.3; P = 0.023), pneumonia (OR, 1.4; 95% CI, 1.0 to 2.0; P = 0.047), and readmission (OR, 1.3; 95% CI, 1.1 to 1.6; P = 0.004). DISCUSSION: The mFI-5 is an independent predictor of morbidity and complications after hemiarthroplasty and THA for femoral neck fracture. Importantly, readmission risk was predicted by the mFI-5. The mFI-5 may present a valuable clinical tool for assessment of high-risk patients who might require additional resources and specialized care after femoral neck fracture.

24-Year-Old Patient with Klippel-Trenaunay Syndrome Underwent Cementless Robotic Cruciate-Retaining TKA: A Case Report.

CASE: A 24-year-old man with Klippel-Trenaunay syndrome (KTS) presented with severe knee osteoarthritis unresponsive to conservative measures. Owing to end-stage, debilitating arthritic symptoms, surgery was pursued. Careful preoperative, multidisciplinary planning/treatment included magnetic resonance imaging to characterize the venous malformations throughout the right lower extremity, preoperative sclerotherapy, sirolimus, and robotic-assisted cementless total knee arthroplasty (TKA). CONCLUSION: Cementless robotic-assisted TKA with selective patellar resurfacing can be a viable option for young KTS patients with severe osteoarthritis when a meticulous multidisciplinary approach, including sclerotherapy and advanced imaging, is undertaken to analyze vascular abnormalities, minimize surgical risks, preserve bone stock, and optimize outcomes.

Impact of Treatment Modalities on Discharge Disposition in Blunt Splenic Injuries.

BACKGROUND: Management of blunt splenic trauma has evolved over several decades, trending towards nonoperative management and splenic artery embolization. Extensive research has been conducted regarding the management of blunt splenic injuries, but there is little data on the association of treatment modality with discharge disposition. METHODS: This is an observational retrospective study conducted at a level-one trauma center with blunt splenic trauma patients of age ≥18 years between January 2010 and December 2021. The primary outcome of unfavorable discharge was defined as discharge to an acute care facility, intermediate care facility, long-term care facility, rehabilitation (inpatient) facility, or skilled nursing facility. RESULTS: Five hundred seventy-nine patients were included in the analysis, with 108 (18.7%) in the unfavorable group and 471 (81.3%) in the favorable group. Most patients were managed nonoperatively (69.3%), followed by splenectomy (25.0%) and embolization (5.7%). Due to the low number of embolizations performed during the study period, treatment modalities were grouped into two broad categories: intervention (embolization and splenectomies) and nonintervention. The treatment modality was found to have no significant impact on unfavorable discharge. Independent risk factors for unfavorable discharge included age >55 years, injury severity score (ISS) >15, hospital-acquired pneumonia, and in-hospital complications of sepsis. CONCLUSIONS: This study provides an understanding of specific demographic and clinical factors that may predispose blunt splenic injury trauma patients to an unfavorable discharge. Providers may apply these data to identify at-risk patients and subsequently adapt the care they provide in an effort to prevent the development of in-hospital pneumonia and sepsis.

Rates of progression of carotid in-stent stenosis and clinical outcomes.

BACKGROUND: We previously reported the incidence of ≥50% and ≥80% carotid in-stent stenosis. In the present study, we analyzed the rate of progression of in-stent stenosis and clinical outcomes with longer follow-up. METHODS: We performed a retrospective analysis of prospectively collected data for 450 patients who had undergone transfemoral carotid artery stenting with longer follow-up (mean, 70 months). The progression of in-stent stenosis was defined as stenosis advancing to a higher severity of disease (ie, from <50% to ≥50% and from ≥50% to ≥80%). Kaplan-Meier analysis was used to estimate the rate of progression from <50% to ≥50% and ≥50% to ≥80%, the overall rates of ≥50% and ≥80% in-stent stenosis, and survival at 1, 3, 5, and 10 years. RESULTS: At a mean follow-up of 70.3 months (range, 1-222 months), 121 of 446 patients (27%) had had progression to ≥50% and 39 (8.7%) to ≥80% in-stent stenosis. Of the 406 patients whose first duplex ultrasound findings were normal or showed in-stent stenosis of <50%, 82 had had progression from normal or <50% to ≥50% in-stent stenosis at a mean of 51.7 months (range, 1-213 months). Of the 121 patients with ≥50% stenosis, 14 (11.6%) had experienced progression to ≥80% at a mean of 33.6 months (range, 6-89 months). Of the 82 patients with progression from <50 to ≥50%, 10 (12%) had experienced a neurologic event (eight transient ischemic attacks [TIAs] and two strokes). Of the 14 with progression from ≥50% to ≥80%, 2 (14.3%) had experienced a TIA, and the remaining patients were asymptomatic. Of the 39 patients with ≥80% in-stent stenosis, 9 (23%) had experienced a neurologic event (eight TIAs and one contralateral stroke). Overall, 13 of the 121 patients with late ≥50% restenosis (10.7%) had experienced a neurologic event (10 ipsilateral TIA, 2 ipsilateral stroke, and 1 contralateral stroke. Thus, 12 of 446 patients (2.7%) had experienced an ipsilateral TIA or stroke at a mean follow-up of 70 months. The rates of freedom from <50% to ≥50% in-stent stenosis progression were 93%, 85%, 78%, and 66% at 1, 3, 5, and 10 years. The rates of freedom from progression from ≥50% to ≥80% in-stent stenosis were 89%, 81%, and 77% at 1, 3, and 5 years, respectively. The overall rates of freedom from ≥50% in-stent stenosis and ≥80% in-stent stenosis were 86%, 77%, 71%, and 59% and 96%, 93%, 91%, and 84% at 1, 3, 5, and 10 years, respectively. Finally, the stroke survival rates were 95%, 80%, 63%, and 31% at 1, 3, 5, and 10 years, respectively. CONCLUSIONS: The rate of progression of carotid in-stent stenosis was modest, with a low incidence of stroke events. Therefore, the use of duplex ultrasound surveillance after carotid artery stenting should be selective and its benefits and utility perhaps reevaluated.

Aortobifemoral bypass for occlusive aortic disease in a patient with a duplicate inferior vena cava.

We present the case of a 66-year-old woman with severe aortoiliac occlusive disease (TASC-D) and an incidental finding of a left sided inferior vena cava, discovered on the preoperative computed tomography scan. This uncommon congenital finding can create intraoperative challenges to the vascular surgeon. In this case report, we have described this anatomic variant and elaborated on our surgical technique to suggest a few tips and tricks for addressing these cases.
