OBJECTIVE: After stroke, the less affected upper-limb shows slight but substantial and longterm motor deficits [1]. Kinematically, this is reflected by an increased segmentation of movements. Here, we aim to define how these changes in behavior are accompanied by changes in brain activation. MATERIAL/PATIENTS AND METHODS: Twenty-one sub-acute post-stroke patients with a first-ever unilateral ischemic stroke of the middle cerebral artery participated in this study twice: within the first 6 weeks post-stroke and after 6 weeks of rehabilitation...

Mesenchymal stem cells (MSCs), which are physiologically maintained in vascular endothelial cell (VEC)-based niches, play a critical role in tissue regeneration. Our previous studies demonstrated that sympathetic denervation could promote MSC mobilization, thereby enhancing bone formation in distraction osteogenesis (DO), a self-tissue engineering for craniofacial and orthopeadic surgeries. However, the mechanisms on how sympathetic neurotransmitter norepinephrine (NE) regulates MSC migration are not well understood...

In recent decades, there has been a call for change among all stakeholders involved in scoliosis management. Parents of children with scoliosis have complained about the so-called "wait and see" approach that far too many doctors use when evaluating children's scoliosis curves between 10° and 25°. Observation, Physiotherapy Scoliosis Specific Exercises (PSSE) and bracing for idiopathic scoliosis during growth are all therapeutic interventions accepted by the 2011 International Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT)...

Ultra-high molecular weight polyethylene (UHMWPE) loaded with alendronate sodium (ALN) has tremendous potential as an orthopeadic biomaterial for joint replacements. However, poor mechanical and tribological properties of UHMWPE-ALN are still obstacle for further application. The purpose of this study was to investigate the effect and mechanism of mechanical activation on mechanical and tribological properties of 1wt% ALN-loaded UHMWPE (UHMWPE-ALN-ma). In this study, tensile test, small punch test and reciprocating sliding wear test were applied to characterize the mechanical and tribological properties of UHMWPE-ALN-ma...

Stem cells are classified by their tissue source. Embryonic stem cells that derived from inner cell mass of blastocyst stage embryos are highly proliferative in their undifferentiated state. A multipotent type of mesenchymal stem cells isolated from different type of tissues such as bone marrow, fat tissue etc. The dynamics of embryonic and adult stem cell cycles are profoundly dissimilar than the culture of stem cells. After improving the culture conditions and differentiation potentials, differentiated stem cells are the first cells to be preferred in modern regenerative medicine and tissue engineering...

BACKGROUND: Bone metastases frequently cause skeletal events in patients with metastatic castration-resistant prostate cancer. Radium-223 dichloride (radium-223) selectively targets bone metastases with high-energy, short-range α-particles. We assessed the effect of radium-223 compared with placebo in patients with castration-resistant prostate cancer and bone metastases. METHODS: In this phase 3, double-blind, randomised ALSYMPCA trial, we enrolled patients who had symptomatic castration-resistant prostate cancer with two or more bone metastases and no known visceral metastases, who were receiving best standard of care, and had previously either received or were unsuitable for docetaxel...

BACKGROUND: Cleft lip and/or palate is the most frequent congenital abnormality occurring in the craniofacial region and is often associated with numerous dental defects such as tooth agenesis, supernumerary teeth, microdontia, taurodontism, crown malformations, or delay in eruption. The prevalence of hypodontia in cleft-affected patients is much higher in comparison with a healthy population. The aim of this study was to evaluate the prevalence of second premolar hypodontia in patients with cleft lip and/or palate...

Both surface chemistry and topography have significant influence on good and fast osseointegration of biomedical implants; the main goals in orthopeadic, dental and maxillofacial surgeries. A surface modification strategy encompassing the use of bioactive trace elements together with surface micron/nano-topographical modifications was employed in this study in an attempt to enhance the osseointegration of Ti alloy (Ti-6Al-4V), a commonly used implant. Briefly, we developed strontium-substituted hardystonite (Sr-HT) ceramic coating with a hierarchical topography where the nanosized grains were superimposed in the micron-rough coating structure...

REVIEW
E Fernandez, P Gastaldi
The hip and its disorders represent a clinical, diagnostic and therapeutic challenge greater than any other joints. Clinical symptoms are usually non specific and provocative maneuvers are sometimes unreliable, pain might be referred even from other joints and many times accurate assessment need imaging techniques. New surgical options, especially the latest development of hip arthroscopy has open horizons for treating intraarticular disorders. In this review article we will review basic clinical assessment and what we need as orthopeadic surgeons from radiology...

The purpose of this study was to investigate the influence of sport, age and different orthopeadical diseases on the variability of gait. 45 healthy, young subjects, 11 professional hand ball players, 24 patients after medial meniscectomy, 20 elderly, healthy subjects, and 20 patients with hip osteoarthritis were examined. The average, the standard deviation and the normalized deviation of spatial and temporal parameters were calculated for each person examined and in each group. Our data suggested that the normalized deviation of parameters enables the modelling of dynamic perception, because it is independent of parameter values due to normalization...

AIM: Training in surgical skills is not at its best in German hospitals in comparison to other countries. There is no detailed curriculum describing which operations a resident has to learn at which stage of his training as in Switzerland or Denmark. We aimed to find out how many typical operations are performed by trainees/residents in orthopaedic surgery. METHOD: We performed a survey at Orthopeadic and Trauma Departments in Germany to measure the percentage of operations (knee arthroscopies, shoulder arthroscopies and knee arthroplasties) which are performed by trainees and residents...

Ability to maintain either static or dynamic balance has been found to be influenced by many factors such as height and weight in the elderly. The relationship between other anthropometric variables and balance performance among elderly Nigerians has not been widely studied. The aim of this study was to investigate the relationship between these other anthropometric variables and balance performance among old individuals aged >60 years in Ibadan, Nigeria. The study used the ex-post facto design and involved two hundred and three apparently healthy (103 males and 100 females) elderly participants with ages between 60 years and 74 years, selected using multiple step-wise sampling techniques from churches, mosques and market place within Ibadan...
