Bipolar hip arthroplasty using conjoined tendon preserving posterior lateral approach in treatment of displaced femoral neck fractures.

Background: Hip fractures account for 23.8% of all fractures in patients over the age of 75 years. More than half of these patients are older than 80 years.

Ankle Arthrodesis Combined With Mosaic Bone Autograft Transplantation for End-Stage Ankle Osteoarthritis With Large Cysts of Talar Dome.

End-stage ankle osteoarthritis with large cysts of talar dome can be challenging to treat. Twenty patients diagnosed as end-stage ankle arthritis with large talar cysts between 04/2010 and 02/2016 were randomly divided into experimental group (10 cases) and conventional group (10 cases) by random number method. Patients in the experimental group were treated with ankle arthrodesis combined with a concomitant procedure of mosaic bone autograft transplantation, the conventional group under the ankle arthrodesis.

Amyloid and tau positive mild cognitive impairment: clinical and biomarker characteristics of dementia progression.

Background: According to the amyloid, tau, neurodegeneration research framework classification, amyloid and tau positive (A+T+) mild cognitive impairment (MCI) individuals are defined as prodromal Alzheimer disease. This study was designed to compare the clinical and biomarker features between A+T+MCI individuals who progressed to progressive MCI (pMCI) and those who remained stable MCI (sMCI), and to identify relevant baseline clinical biomarker and features that could be used to predict progression to dementia within 2 years.

Methods: We stratified 197 A+T+MCI individuals into pMCI (n = 64) and sMCI (n = 133) over 2 years.

Comparison of new-generation drug-eluting stents versus drug-coated balloon for in-stent restenosis: a meta-analysis of randomised controlled trials.

Objective: The study sought to compare angiographic and clinical outcomes of new-generation drug-eluting stents (DES) versus drug-coated balloon (DCB) in patients with coronary in-stent restenosis (ISR).

Design: Meta-analysis using data from randomised trial found by searches on PubMed, the Cochrane Library, ClinicalTrials.gov and websites of major cardiovascular congresses.

Comparative Efficacy of Antihypertensive Agents in Salt-Sensitive Hypertensive Patients: A Network Meta-Analysis.

Background: Salt-sensitive hypertension (SSH) is an intermediate inherited phenotype of essential hypertension as well as being an independent risk factor for cardiovascular disease. However, effective medications for the treatment of SSH have not been clarified. This study was to compare the efficacious of different classes of antihypertensive agents combined with salt intake on the reduction of blood pressure (BP) in patients with SSH.

Mid term results of total hip arthroplasty using polyethylene-ceramic composite (Sandwich) liner.

Background: Ceramic-on-ceramic (COC) couplings are an attractive alternative bearing surfaces that have been reported to eliminate or reduce problems related to polyethylene wear debris. However, the material in total hip arthroplasty (THA) remains one of the major concern regarding the risk of fracture. The present study aims at reporting the fracture rate of bearings in a series of COC THAs with the use of a sandwich liner and attempt to detect the relative risk factors, the possible cause and assess the clinical results.

Comparison of intravascular ultrasound guided versus angiography guided drug eluting stent implantation: a systematic review and meta-analysis.

Background: Intravascular ultrasound (IVUS) can be a useful tool during drug-eluting stents (DES) implantation as it allows accurate assessment of lesion severity and optimal treatment planning. However, numerous reports have shown that IVUS guided percutaneous coronary intervention is not associated with improved clinical outcomes, especially in non-complex patients and lesions.

Methods: We searched the literature in Medline, the Cochrane Library, and other internet sources to identify studies that compare clinical outcomes between IVUS-guided and angiography-guided DES implantation.

A novel fixation system for acetabular quadrilateral plate fracture: a comparative biomechanical study.

This study aims to assess the biomechanical properties of a novel fixation system (named AFRIF) and to compare it with other five different fixation techniques for quadrilateral plate fractures. This in vitro biomechanical experiment has shown that the multidirectional titanium fixation (MTF) and pelvic brim long screws fixation (PBSF) provided the strongest fixation for quadrilateral plate fracture; the better biomechanical performance of the AFRIF compared with the T-shaped plate fixation (TPF), L-shaped plate fixation (LPF), and H-shaped plate fixation (HPF); AFRIF gives reasonable stability of treatment for quadrilateral plate fracture and may offer a better solution for comminuted quadrilateral plate fractures or free floating medial wall fracture and be reliable in preventing protrusion of femoral head.

Impact of everolimus versus other rapamycin derivative-eluting stents on clinical outcomes in patients with coronary artery disease: a meta-analysis of 16 randomized trials.

Background: Everolimus-eluting stent (EES) are considered to have better clinical outcomes than other rapamycin derivative-eluting stents; however, the individual trials may not have sufficient power to prove it. This meta-analysis aimed to compare clinical outcomes of EES against other rapamycin derivative-eluting stents.

Methods: We searched Medline, the Cochrane Library, and other internet sources, without language or date restrictions for articles comparing clinical outcomes between EES and other rapamycin derivative-eluting stents.

Less anterior knee pain with a routine lateral release in total knee arthroplasty without patellar resurfacing: a prospective, randomized study.

Purpose: Anterior knee pain is a major cause of complaint in total knee arthroplasty (TKA) without patellar resurfacing. The concept of improved patellar tracking and decreased retropatellar contact pressure for lateral retinacular release theoretically suggests that patients with lateral retinacular release in TKA would achieve a lower incidence of anterior knee pain when compared without lateral retinacular release. We sought to determine (1) whether those patients who received a routine lateral retinacular release in TKA would attain lower incidence of anterior knee pain as compared to patients who received TKA without lateral retinacular release and (2) whether lateral retinacular release would increase the lateral retinacular release-related complications.

Adhesion of osteoblast-like cell on silicon-doped TiO2 film prepared by cathodic arc deposition.

Silicon-doped TiO2 (Si-TiO2) and pure TiO2 films were deposited on titanium substrates by cathodic arc deposition technique. The surface characteristics of the films, such as surface topography, elemental composition and wettability, were studied. About 4.

Predictors of clinical outcomes after surgical treatment of displaced acetabular fractures in the elderly.

Outcomes following the open reduction and internal fixation (ORIF) of displaced acetabular fractures in the elderly have been inconsistent. Several factors associated with significant poor clinical outcomes have been reported; however, the factor that contributes independently to the outcomes remains unknown. This study aims to identify independent prognostic factors for the outcomes of surgically treated displaced acetabular fractures in the elderly.
