#1
Harini Pattabhiraman, Marjolein Dijkstra
Using Monte Carlo simulations and free-energy calculations, we study the phase behaviour of a two-dimensional system of particles interacting with a hard core of diameter σHD and a repulsive square shoulder potential. The interest in this system lies in the formation of quasicrystals of different symmetries at specific square-shoulder widths δ as previously reported by Dotera et al. [Nature 506, 208 (2014)]. However, an insight into other possible periodic phases formed in these systems and the thermodynamic stability of both the periodic and quasicrystal phases is yet to be addressed...

The development of clinical implant dentistry was intensively affected by dental implant design improvement and innovation, which brought about new concept, even milestone-like changes of clinical protocol. The current improvements of dental implant design and their clinical importance could be highlighted as followings: 1) The implant apical design influences the implant preliminary stability in immediate implant. The apical 3-5 mm design of implant makes implant stable in immediate implant, because this part would be screwed into alveolar bone through fresh socket, the other part of implant could not be tightly screwed in the socket because of smaller implant diameter...

We investigated whether and how the movement initiation condition (IC) encountered during the early movements performed following focal muscle fatigue affects the postural control of discrete ballistic movements. For this purpose, subjects performed shoulder flexions in a standing posture at maximal velocity under two movement IC, i.e., in self-paced conditions and submitted to a Stroop-like task in which participants had to trigger fast shoulder flexions at the presentation of incongruent colors. Shoulder flexion kinematics, surface muscle activity of focal and postural muscles as well as center-of-pressure kinematics were recorded...

INTRODUCTION: Controversy exists on optimal operative treatment of vertically unstable Neer IIB lateral clavicle fractures. Aim of this study was to analyse and compare clinical and radiological results and complications of locking plate osteosynthesis (LPO) versus hook plate osteosynthesis (HPO) with acromioclavicular joint (ACJ) stabilization. The hypothesis was, that HPO would recreate coracoclavicular stability more effectively and potentially lead to a superior outcome. METHODS: This retrospective, observational cohort study included 32 patients (19 HPO, 13 LPO) with a mean age of 44...

BACKGROUND: Postural development progresses through a series of stages (growth spurts, development of balance and coordination, postural stability) which occur when children are at school age. The reduction in the level of physical activity, increased body weight, overloaded school bags, asymmetry of the backpack straps, the method of putting on and taking off the backpacks and increased usage of electronic devices have negative side effects such as bad body posture habits. METHODS: A prospective cohort study in the group of 155 pupils at early school age 7-9 years old has been conducted...

Cervical vertebrae are rare in the early hominin fossil record, presenting a challenge for understanding the evolution of the neck and head carriage in hominin evolution. Here, we examine the cervical vertebrae of Australopithecus sediba, which unlike other South African taxa is known from associated cervical vertebrae. The A. sediba cervical vertebrae exhibit human-like values for wedging, pedicle cross-sectional areas, and articular facet heights, indicating reduced ventral loading relative to African apes...

Open reduction and internal fixation of complex proximal humeral fracture represents a surgical challenge. The main objective of this procedure is to anatomically reduce the tuberosities. We propose a standardized and reproducible technique that we apply to all complex displaced 3- and 4-part fractures of patients under 50 years. We use an antero-lateral trans-deltoid approach; the humeral head and the tuberosities are reduced under fluoroscopic control. The tuberosities are stabilized with an inter-tuberosity osteosuture, and we then introduce a thin and straight intra-medullary nail (Telegraph IV FH Orthopedics) at the hinge point of the humeral head...

PURPOSE: To analyze and compare patient expectations of primary and revision shoulder stabilization and to assess the factors associated with patients' expectations. METHODS: Pre-operative patient expectations after shoulder instability repair were prospectively assessed using a self-designed questionnaire. The survey included questions on the expected level and type of return to sports, instability, pain, risk of osteoarthritis, and overall shoulder condition. RESULTS: One-hundred and forty-five patients (99 primary; 46 revision repair) were included...

Recurve archery is an Olympic sport that requires extreme precision, upper body strength and endurance. The purpose of this research was to quantify how postural stability variables both pre- and post-arrow release, draw force, flight time, arrow length and clicker reaction time, collectively, impacted on the performance or scoring outcomes in elite recurve archery athletes. Thirty-nine elite-level recurve archers (23 male and 16 female; mean age = 24.7 ± 7.3 years) from four different countries volunteered to participate in this study prior to competing at a World Cup event...

PURPOSE: Arthroscopic Bankart repair (ABR) provides satisfactory results for recurrent anterior shoulder instability, but the high recurrence rate post-ABR remain a concern. One of the adjunct procedures proposed to improve ABR results is arthroscopic rotator interval closure (ARIC). This study prospectively evaluated the outcomes of ABRs alone compared to combined ABR + ARIC and identified risk factors related to failure of each procedure. METHODS: Thirty-nine consecutive patients (mean age 23...

Proximal humerus fractures are characterized by their frequency, the difficulties and the absence of treatment of reference. New means of osteosynthesis appeared since the years 2000, as well as the preferential recourse to the reversed prostheses of shoulder. A chapter is dedicated to classifications, as a whole not very reproducible. The new treatments are represented by the nails, such as Telegraph(®), and the plates with blocked screws. It appeared a real progress in the osteosyntheses and became infinitely more solid with the stability of the screws in the bone...

Shoulder range of motion (ROM) in throwing athletes relies on a balance of mobility and stability in order to maintain proper function and health. Prior research has reported that deficits in internal rotation greater than 20 degrees, decreases in total arc of motion greater than 5 degrees when compared to the contralateral side, and decreases in horizontal adduction greater than 16 degrees have all been identified as factors that could lead to throwing related injuries.(1) Due to the increased risk of injury associated with ROM deficits, it is important for clinicians to be cognizant of how to most effectively treat these issues...

STUDY DESIGN: Repeated cross-sectional study. INTRODUCTION: Multiple studies have evaluated the psychometric properties of the Simple Shoulder Test (SST) through traditional methods supporting it as valid and reliable. Since the evidentiary pool supporting the use of the SST has only partially addressed key measurement properties and the development of SST pre-dates the common use of Rasch model, validation of SST has become a necessity to establish as a reliable and valid PRO for shoulder conditions...

BACKGROUND: The humerus shaft is one of the sites with the largest probability of developing pseudoarthrosis after fracture. We present the results of nine patients with atrophic pseudoarthrosis of humeral shaft treated with angular stability plate associated with allograft and platelet-rich plasma (PRP), after a first treatment with intramedullary nail to correct the fracture. MATERIAL AND METHODS: From January 2012 to December 2014, nine patients were treated for atrophic pseudoarthrosis (PSA) of humeral shaft treated previously using intramedullary nail; seven humeral diaphysis fractures were located in the middle-proximal third and two in the middle third...

Bipolar bone loss in patients with anterior glenohumeral instability is challenging to treat. The goal of the treatment is to restore stability by ensuring that the humeral head remains within the glenoid vault. This can be achieved either with the combination of an arthroscopic Bankart procedure and remplissage (glenoid bone loss <25%), or with a Latarjet procedure (glenoid bone loss >25%). In cases with more severe bipolar bone loss of both the glenoid and the humeral head, the conventional approach has been to lengthen the articular arc of the glenoid and to ignore the Hill-Sachs lesion...

PURPOSE: the past decade has seen a considerable increase in the use of research models to study reverse total shoulder arthroplasty (RTSA). Nevertheless, none of these models has been shown to completely reflect real in vivo conditions. METHODS: we performed a systematic review of the literature matching the following key words: "reverse total shoulder arthroplasty" or "reverse total shoulder replacement" or "reverse total shoulder prosthesis" and "research models" or "biomechanical models" or "physical simulators" or "virtual simulators"...

BACKGROUND AND PURPOSE: Shoulder instability, a common issue among athletes who engage in contact sports, may lead to recurrent subluxations, or partial dislocations of the shoulder. Young athletic patients generally respond poorly to the nonsurgical treatments for shoulder instability that are commonly utilized. The purpose of this case report is to describe the effects of the treatment guided by the Mulligan Concept (MC) coupled with reflex neuromuscular stabilization (RNS) also known as reactive neuromuscular training (RNT), on an adolescent football player with glenohumeral joint (GHJ) instability who sustained a traumatic anterior subluxation...
