PURPOSE Use of tranexamic acid (TXA) in the setting of arthroplasty of the lower extremity has been previously described. The aim of this study was to evaluate the benefit of a single dose of TXA (500 mg vial) administered intravenously just prior to RTSA in an Asian population. METHODS The records of 48 patients (no TXA, n = 24, versus TXA, n = 24) that underwent RTSA for cuff tear arthropat...

INTRODUCTION Patients may experience a loss of internal rotation (IR) and external rotation (ER) after reverse total shoulder arthroplasty (RTSA). We hypothesized that alterations in the glenosphere position will affect the amount of impingement-free IR and ER. MATERIALS AND METHODS Computed tomography (CT) scans of the scapula and humerus were obtained from 7 cadaveric specimens, and 3-dimen...

Objective. To conduct a comparative retrospective analysis of the anatomical and functional results surgical treatment proximal humerus fractures AO/OTA 11-B, 11-C using different methods in patients over 50 years old with osteoporosis to justify differential approach. Methods. The study included 102 aged older 11-C. were divided into three groups: I — (16 men, 34 women) whom performed open red...

Abstract Introduction Proximal humeral fractures (PHF) are one of the most challenging injuries to treat and recover from. Humeral fracture stems have become popular among individuals undergoing arthroplasty because their superior ability reduce repair tuberosities. This study aims determine better clinical, functional, radiology outcomes cost-effectiveness surgical management PHF Comparison th...

BACKGROUND The purpose of this study was to investigate the results and complications during the learning curve of reverse total shoulder arthroplasty (RTSA) for rotator cuff deficiency. METHODS We retrospectively reviewed the first 40 cases of RTSA performed by a single surgeon. The mean age of patients was 72.7 years (range, 63 to 81 years) and mean follow-up period was 26.7 months (range, ...

BACKGROUND Reverse shoulder prostheses are increasingly used in recent years for treatment of glenohumeral arthropathy with deficient rotator cuff. Bone preservation is becoming a major goal in shoulder replacement surgery. Metaphyseal humeral components without a stem were developed to minimize bone resection and preserve bone. This study evaluated the clinical and radiologic outcomes at 2 to ...

Upon contact with intestinal epithelial cells, Salmonella enterica serovar Typhimurium injects a set of effector proteins into the host cell cytoplasm via the Salmonella pathogenicity island 1 (SPI1) type III secretion system (T3SS) to induce inflammatory diarrhea and bacterial uptake. The master SPI1 regulatory gene hilA is controlled directly by three AraC-like regulators: HilD, HilC, and Rts...

abstract: â in this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13x zeolite in a fixed-bed adsorption tower which is used to capture co2 from both humid and dry nitrogen stream under industrial conditions. the results show that the performance of amine-grafted adsorbent and 13x zeolite is almost the same in the dry ...

Objectives: Rotator cuff tears cause pain, muscle weakness, and difficulty with overhead activity. While smaller are easier to repair, large-to-massive (>3 cm in size) considered irreparable. For patients tears, surgical options include maximal superior capsular reconstruction, bridging tendon transfers reverse total shoulder arthroplasty (rTSA). Bridging reconstruction was developed improve...
