BACKGROUND Conventional stemmed anatomical shoulder prostheses are widely used in the treatment of glenohumeral osteoarthritis. The stemless shoulder prosthesis, in contrast, is a new concept, and fewer outcome studies are available. Therefore, the purpose of the study was to investigate the early functional outcome and postoperative proprioception of a stemless prosthesis in comparison with a ...

INTRODUCTION Short-stemmed hip implants have been introduced in order to conserve proximal bone mass and could facilitate the use of minimally invasive surgery (MIS), in which smaller incisions limit access to the hip joint. MIS techniques have been associated with faster rehabilitation, reduced peri-operative blood loss and less post-operative pain [1]. The limited access during MIS may increa...

Fifty-three failed knee replacements were revised using minimally constrained implants with smooth uncemented intramedullary stems and metal-backed tibial components. Polymethylmethacrylate was used only to replace lost bone near the surface of the implant. Excluding four knees which had serious postoperative complications, 91% had successful relief of pain, 84% had over 90 degrees of movement ...

background: a qualitative study was carried out on 200 pregnant women attending obstetric offices and imam ali women's clinic in zahedan, iran during january 2010 to august 2011. twenty-nine focus group discussions (fgds) with 5-8 participants in each group were formed. the study included women in the third trimester of pregnancy with the intention or decision to undergo elective cesarean secti...

The wheat stem sawfly (WSS) is an economically important pest of wheat in the Northern Great Plains. The primary means of WSS control is resistance associated with the single quantitative trait locus (QTL) , which controls most stem solidness variation. The goal of this study was to identify stem solidness candidate genes via RNA-seq. This study made use of 28 single nucleotide polymorphism (SN...

Sentiment analysis using stemmed Twitter data from various languages is an emerging research topic. In this paper, we address three augmentation techniques namely Shift, Shuffle, and Hybrid to increase the size of training data; then use key types deep learning (DL) models recurrent neural network (RNN), convolution (CNN), hierarchical attention (HAN) classify Turkish for sentiment analysis. Th...

OBJECTIVE To present the results of total knee replacement at the King Abdul-Aziz University Hospital in Jeddah, Kingdom of Saudi Arabia (KSA). METHODS The medical records of 205 patients who received 309 prostheses was reviewed. The study took place at King Abdul-Aziz University Hospital, Jeddah, KSA between May 1989 and August 2005, where patients were either examined in the outpatient clin...

Bone remodeling of a metaphyseal fixed femoral stem, Mayo Conservative Hip (Zimmer International, Warsaw, Ind), was characterized by the dual-energy x-ray absorptiometry and a mathematical remodeling model. The mean age of the patient was 50.8 years, and the mean follow-up was 5.7 years. As anticipated, bony structure underwent significant remodeling after the short-stemmed femoral arthroplasty...
