A New Postoperative Stability Score to Predict Loss of Reduction in Intertrochanteric Fractures in Elderly Patients.

The study aimed to validate a newly developed postoperative stability score for evaluating clinical follow-up in elderly patients with low-energy hip fractures. From 1 January 2020 to 31 December 2021, we enrolled patients aged over 65 who underwent cephalomedullary nail fixation using proximal femoral nail antirotation II (PFNAII) and had at least 6 months of follow-up; excluding multiple fractures, pathological fractures, and periprosthetic fractures. We collected general patient data.

Comparison of primary total hip arthroplasty with limited open reduction and internal fixation vs open reduction and internal fixation for geriatric acetabular fractures: a systematic review and meta-analysis.

Purpose: Comminuted fractures with poor bone quality in the elderly are associated with poor outcomes. An alternative to open reduction and internal fixation (ORIF) alone, primary or acute total hip arthroplasty (aTHA), allows early mobilization with full weight bearing. In this study, we aim to analyze whether treatment of aTHA with/withtout ORIF (limited ORIF) vs ORIF alone yields better intra-operative results, functional outcomes, and less complications.

Quantification of the Safe Zone of the First to Third Sacral Segments for Transiliac-Transsacral Screw Fixation in Normal and Dysmorphic Sacra.

Transiliac-transsacral screw fixation is widely used to stabilize unstable posterior pelvic ring injuries. Preoperative radiographic assessment of the safe osseous corridor is necessary because the safe space of sacrum is narrower for transiliac-transsacral screw placement than for traditional iliosacral screw placement. However, the radiographic assessment has rarely been studied in the Taiwanese population.

"Fragment Width Ratio" as a Predictor of Nonunion for Femoral Shaft Fracture With Third Fragments.

Previous studies have reported that large fracture fragment with displacement might cause nonunion of femoral shaft fractures. We therefore intended to delineate significant risk factors for developing a nonunion predisposed by a major fracture fragment. We analyzed 61 patients who were operated on using interlocking nails for femoral shaft fractures from 2009 to 2018.

Using Trident distal radial locking plate to fix the fracture of distal radius volar rim.

Background: The volar locking plates have been widely used in a variety of distal radius fractures, but they still have several limitations when dealing with small fragments located around the watershed line with widely reported complications. The volar rim fragments play a critical role in radiocarpal joint stability and failing to secure the volar rim fragment usually results in carpal instability, subluxation, or even dislocation. This study investigates clinical outcomes in the use of a novel implant, the Trident distal radial (TDR) locking plate to treat distal radius fracture with the intermedium column edge (lunate fossa volar rim) fragment involvement.

Leveraging single-cell Raman spectroscopy and single-cell sorting for the detection and identification of yeast infections.

Invasive fungal infection serves as a great threat to human health. Discrimination between fungal and bacterial infections at the earliest stage is vital for effective clinic practice; however, traditional culture-dependent microscopic diagnosis of fungal infection usually requires several days, meanwhile, culture-independent immunological and molecular methods are limited by the detectable type of pathogens and the issues with high false-positive rates. In this study, we proposed a novel culture-independent phenotyping method based on single-cell Raman spectroscopy for the rapid discrimination between fungal and bacterial infections.

Stain-free Gram staining classification of pathogens single-cell Raman spectroscopy combined with machine learning.

Gram staining (GS) is one of the routine microbiological operations to classify bacteria based on the cell wall structure. Accurate GS classification of pathogens is of great significance since it helps correct administration of antimicrobial treatment. The laborious procedure and low sensitivity results related to conventional GS have resulted in reluctance among clinicians.

Design, Synthesis, and Application of Carbon Dots With Synergistic Antibacterial Activity.

The diversity of bacteria and their ability to acquire drug resistance lead to many challenges in traditional antibacterial methods. Photothermal therapies that convert light energy into localized physical heat to kill target microorganisms do not induce resistance and provide an alternative for antibacterial treatment. However, many photothermal materials cannot specifically target bacteria, which can lead to thermal damage to normal tissues, thus seriously affecting their biological applications.

Combining a transosseous cerclage wire after patellar tendon reattachment to treat patella distal pole fracture did not improve functional outcome.

This study aims to investigate whether an augmented wire in the treatment of patella distal pole fracture could improve knee range of motion (ROM) and radiographic features. Thirty-five consecutive patients with patellar distal pole fracture were analyzed from January 2014 to July 2019. The treatment is divided into two groups according to the presence or absence of augmented wire.

Single Cell Raman Spectroscopy Deuterium Isotope Probing for Rapid Antimicrobial Susceptibility Test of spp.

Nosocomial infection by multi-drug resistance spp. is an emerging concern with severe clinical consequences, particularly in immunocompromised individuals and infants. Efficient control of this infection requires quick and reliable methods to determine the appropriate drugs for treatment.

[Analysis of the Effects of Femoral Nerve Block on Pain Level and Knee Mobility in Patients With Total Knee Replacement].

Background: Osteoarthritis is a common cause of inactivity and reduced quality of life in the elderly. Total knee replacement (TKR) surgery, a last-stage treatment option for osteoarthritis, often results in postoperative pain that influences knee flexion and the ability to perform prescribed rehabilitation exercises.

Purpose: This study was designed to examine the effectiveness of single femoral nerve block (FNB) on pain level and knee mobility in patients with TKR.

The radiographic outcome after plating for pubic symphysis diastasis: does it matter clinically?

Introduction: Open reduction and internal fixation with plates is the most widespread surgery in traumatic pubic symphysis diastasis. However, implant failure or recurrent diastasis was commonly observed during follow-up. The aim of our study was to evaluate the radiologic findings and clinical outcomes.

Functional outcomes following fixation of a marginal distal radius fracture with two commonly used volar locking plates: a retrospective cohort study.

Introduction: The volar locking plate has been widely used for unstable distal radius fractures to provide early recovery of wrist function. Volar plate prominence to the watershed line has been reported to be related to flexor tendon irritation, and avoid implant prominence in this area was suggested. On the other hand, marginal distal radius fracture patterns required the plate to cross the watershed line, making conflict over plate positioning on marginal distal radius fractures.

Immediate application of negative pressure wound therapy following lower extremity flap reconstruction in sixteen patients.

Negative pressure wound therapy (NPWT) is usually applied in wound management and soft-tissue salvage after the development of complications. However, immediate postoperative application of NPWT over the flap coverage is seldom reported. We evaluate the effectiveness of immediate postoperative application of NPWT following fasciocutaneous or muscle flap coverage for lower leg reconstruction.

Single pulley double-strand anchor suture fixation of the coronoid process in terrible triad of the elbow injury.

Background: Terrible triad of the elbow injury is difficult to manage, and the role of the coronoid process in instability is very important. We describe a simple, modified suture technique to fix a coronoid process fragment using suture anchor fixation.

Methods: Eight patients (three female and five male) with coronoid process injuries with the fragment involving <50% of the total height (Regan-Morrey type I/II) in terrible triad of elbow injury were included.

Concomitant Acromioclavicular and Coracoclavicular Ligament Reconstruction with a Duo-Figure-8 Autogenic Graft Wrapping Technique for Treating Chronic Acromioclavicular Separation.

Backgroud: Coracoacromial ligament transfer is the traditional procedure for treating chronic acromioclavicular separation, but it is significantly inferior to ligament reconstruction according to biomechanical and clinical studies. However, ligament reconstruction carries the risk of complications of graft loosening and peri-tunnel fractures. Currently, there is no ligament reconstruction procedure optimal for preventing such complications.

In Vitro Anticancer Drug Sensitivity Sensing through Single-Cell Raman Spectroscopy.

Traditional in vitro anticancer drug sensitivity testing at the population level suffers from lengthy procedures and high false positive rates. To overcome these defects, we built a confocal Raman microscopy sensing system and proposed a single-cell approach via Raman-deuterium isotope probing (Raman-DIP) as a rapid and reliable in vitro drug efficacy evaluation method. Raman-DIP detected the incorporation of deuterium into the cell, which correlated with the metabolic activity of the cell.

The elastic stable intramedullary nails as an alternative treatment for adult humeral shaft fractures.

Background: Plate and locked intramedullary nailing for humeral fractures are golden standard procedure, but the humerus is a nonweight-bearing bone and can tolerate a larger range of acceptable alignment. We believe the elastic stable intramedullary nails (ESINs) can provide enough relative stability for humeral shaft fractures in certain adult patients.

Methods: There are four new indications for using ESINs: (1) patient could not tolerate a sugar-tong splint but was a high risk for general anesthesia, (2) intramedullary canal narrowing (<7 mm), (3) long spiral or oblique fracture over the metadiaphyseal junction, and (4) obesity.

Development of a Fast Raman-Assisted Antibiotic Susceptibility Test (FRAST) for the Antibiotic Resistance Analysis of Clinical Urine and Blood Samples.

Human health is at great risk due to the spreading of antimicrobial resistance (AMR). The lengthy procedure of conventional antimicrobial susceptibility testing (AST) usually requires a few days. We developed a fast Raman-assisted antibiotic susceptibility test (FRAST), which detects single bacterial metabolic activity in the presence of antibiotics, using Raman single-cell spectroscopy.

A novel low-profile external skeletal fixator for type IIIB open tibial fractures: A biomechanical and clinical pilot study.

Background: Although external fixator is standard for managing staged treatment of open tibial fracture, the main disadvantage of this device is too bulky to be tolerated by most patients for longtime use. The purposes of this pilot study were to compare the biomechanical properties of a novel low-profile external fixator (LP-ESF) with a traditional ESF and also to evaluate its performance in patients with Gustilo type IIIb tibial open fractures.

Methods: A prospective clinical pilot study started from January 2015 to December 2017, and 18 patients with Gustilo type IIIb open tibial fractures underwent the fixation with a novel LP-ESF system.

Peri-implant Fractures Following Hook Plate Fixation for Unstable Distal Clavicle Fractures.

Clavicle hook plate is a common implant for treating distal clavicle fracture. Although high bone union rate and good functional outcome have been reported, so have several complications, such as osteolysis and fracture of the acromion, loss reduction, hook impingement, and rotator cuff tear. Peri-implant fracture over the medial side of the hook plate is a rare complication.

[Conducting clinical studies during the epidemics of communicable diseases: perspectives of methodology and health economics].

In the setting of epidemics of communicable diseases, early initiation of epidemiological and clinical data collection and analysis and conducting relevant researches are essential to the success of epidemic containment. The coronavirus disease 2019 (COVID-19), starting initially as an epidemic in China in late 2019 and now becoming a pandemic globally, poses grave challenges to the global health care systems while also provides an opportunity for studying infectious diseases in the perspective of methodology. The authors propose the evaluation methods for case reports, randomized controlled trials (RCTs), real-world evidence studies and health economics researches during an epidemic.
