Use of Permanently Placed Metal Expandable Cages for Vertebral Body Reconstruction in the Surgical Treatment of Spondylodiscitis
Authors: Calvert Graham , May Larry A. , Theiss Steven
Published: June 2014

This is a retrospective study of 15 patients treated for spondylodiscitis with implanted metal cages. The purpose of this study is to investigate the outcomes of patients treated with permanently placed metal hardware in vertebral body reconstruction for spondylodiscitis. The use of metal implants in the face of infection has classically been discouraged in orthopedic literature because of the ability of bacteria to form biofilms on metal surfaces. Traditional treatment of spondylodiscitis has been aggressive debridement followed by reconstruction with bone grafts. Expandable metallic cages made reconstruction of these defects significantly easier. However, concern exists that metallic implants affect the resolution of infection. A search of the authors’ patient database from 2005 to 2009 revealed 21 patients with spondylodiscitis treated with anterior debridement and reconstruction with an expandable metallic cage. Fourteen patients (15 cases) had sufficient documented clinical follow-up and were available for review. Resolution of infection was determined by evaluating symptoms, laboratory data, and final radiographic result. Of the 15 cases, all had clinical resolution of infection with an average follow-up time of 25 months. An average loss of 1.9° of correction was observed when comparing final follow-up radiographs with initial postoperative radiographs. Radiograph review revealed no extensive osteolysis around the hardware or progressive collapse. These results suggest that the use of expandable metal cages maintains alignment while not perpetuating infection. The spine appears to provide a unique environment that permits the use of metal implants in the setting of infection.
Effect of Intra-articular Injection of Tranexamic Acid on Postoperative Hemoglobin in Total Hip Arthroplasty
Authors: Bagsby Deren T. , Hur John
Published: June 2014

Postoperative anemia is a significant risk factor in total hip arthroplasty, leading to increased length of hospital stay and delayed mobility and rehabilitation, and is poorly tolerated by patients with peripheral vascular and cardiovascular disease. Intravenous tranexamic acid, an antifibrinolytic drug, has been shown to reduce postoperative anemia in total joint replacement. Intra-articular administration eliminates the risk of systemic effects, the most concerning of which is thrombosis. Although this method of administering tranexamic acid has been studied in total knee replacement, currently no literature has been published on its efficacy in primary total hip replacement. The purpose of this study was to examine postoperative hemoglobin decrease and the transfusion rate following intra-articular tranexamic acid administration in primary total hip arthroplasty. The authors conducted a retrospective review of 181 consecutive total hip replacements, 91 of which received tranexamic acid. No statistical significance was found between these groups in any of the demographic variables. Postoperative hemoglobin decrease in the control group was 4.4±1.0 g/dL compared with a decrease of 3.6±1.1 g/dL in the tranexamic group, demonstrating an 18% reduction in blood loss (
P
<.001). No significant difference was found between the number of patients transfused (
P
=.777) or the number of units used (
P
=.993). No clotting events were seen in either group. Overall, the study demonstrates that intra-articular tranexamic acid in primary total hip arthroplasty is associated with a significant improvement in postoperative hemoglobin decrease without systemic hypercoagulability.

Published: June 2014

Level I trauma centers frequently see trauma at or below the ankle, which requires consultation with the orthopedic surgery department. However, as podiatry programs begin to firmly establish themselves in more Level I trauma centers, their consultations increase, ultimately taking those once seen by orthopedic surgery. A review of the literature demonstrates that this paradigm shift has yet to be discussed. The purpose of this study was to determine how many, if any, lower extremity fracture consultations a newly developed podiatry program would take from the orthopedic surgery department. A retrospective review was performed of emergency department records from January 2007 to December 2011. Seventeen different emergency department diagnoses were used to search the database. Ultimately, each patient’s emergency department course was researched. Several trends were noted. First, if trauma surgery was involved, only the orthopedic surgery department was consulted for any injuries at or below the ankle. Second, the emergency department tended to consult the podiatry program only between the hours of 8
am
and 6
pm
. Third, as the podiatry program became more established, their number of consultations increased yearly, and, coincidentally, the orthopedic surgery department’s consultations decreased. Finally, high-energy traumas involved only the orthopedic surgery department. Whether the orthopedic surgery department or podiatry program is consulted regarding trauma surgery is likely hospital dependent.

Published: June 2014

Led by the federal government, the payers of health care are enacting policies designed to base provider reimbursement on the quality of care they render. This study evaluated and compared patient experiences and satisfaction with nasal decolonization with either nasal povidone-iodine (PI) or nasal mupirocin ointment (MO). A total of 1903 patients were randomized to undergo preoperative nasal decolonization with either nasal MO or PI solution. All randomized patients were also given 2% chlorhexidine gluconate topical wipes. Patients were interviewed prior to discharge to assess adverse events and patient experience with their assigned preoperative antiseptic protocol. Of the 1903 randomized patients, 1679 (88.1%) were interviewed prior to discharge. Of patients receiving PI, 3.4% reported an unpleasant or very unpleasant experience, compared with 38.8% of those using nasal MO (
P
<.0001). Sixty-seven percent of patients using nasal MO believed it to be somewhat or very helpful in reducing surgical site infections, compared with 71% of patients receiving PI (
P
>.05). Being recruited as an active participant in surgical site infection prevention was a positive experience for 87.2% of MO patients and 86.3% of PI patients (
P=
.652). Those assigned to receive PI solution preoperatively reported significantly fewer adverse events than the nasal MO group (
P
<.01). Preoperative nasal decolonization with either nasal PI or MO was considered somewhat or very helpful by more than two-thirds of patients.

Published: June 2014

A subset of patients undergoing primary total shoulder arthroplasty (TSA) have a medialized joint line secondary to glenoid wear. In some cases, the central pegs or peripheral pegs of a peg design glenoid component may violate the medial cortex of the glenoid vault. It is unknown whether this leads to early failure. The objectives of this study were to determine (1) whether glenoid components with uncontained pegs would be associated with a high rate of failure and (2) whether peg perforation would be associated with inferior clinical outcomes. The authors performed a case-control retrospective review comparing 25 TSAs in which one or multiple pegs perforated the medial glenoid vault (uncontained group) with 25 TSAs without peg perforation (contained group). Implant survival was calculated with revision for glenoid component loosening as the primary outcome variable. Clinical outcomes were determined using American Shoulder and Elbow Surgeons (ASES) and Penn Shoulder Scores. Average follow-up was more than 5 years. No patient in either group had symptomatic glenoid loosening. Two (8%) patients in the uncontained group required revision for rotator cuff tears. Penn and ASES scores were significantly lower in the uncontained group (Penn,
P
=.002; ASES,
P
=.004). Pain and satisfaction subscores were similar between the groups, but function subscores were significantly lower in the uncontained group (Penn,
P
=.002; ASES,
P
=.005). Uncontained pegs of an anchor peg glenoid component are not associated with early glenoid loosening. Similar pain relief is obtained when compared with contained glenoid components, but shoulder function is significantly lower in patients with uncontained pegs.
Spontaneous Modular Femoral Head Dissociation Complicating Total Hip Arthroplasty
Authors: Talmo Carl T. , Sharp Kinzie G. , Malinowska Magdalena , Bono James V. , Ward Daniel M. , Lareau Justin
Published: June 2014

Modular femoral heads have been used successfully for many years in total hip arthroplasty. Few complications have been reported for the modular Morse taper connection between the femoral head and trunnion of the stem in metal-on-polyethylene bearings. Although there has always been some concern over the potential for fretting, corrosion, and generation of particulate debris at the modular junction, this was not considered a significant clinical problem. More recently, concern has increased because fretting and corrosive debris have resulted in rare cases of pain, adverse local tissue reaction, pseudotumor, and osteolysis. Larger femoral heads, which have gained popularity in total hip arthroplasty, are suspected to increase the potential for local and systemic complications of fretting, corrosion, and generation of metal ions because of greater torque at the modular junction. A less common complication is dissociation of the modular femoral heads. Morse taper dissociation has been reported in the literature, mainly in association with a traumatic event, such as closed reduction of a dislocation or fatigue fracture of the femoral neck of a prosthesis. This report describes 3 cases of spontaneous dissociation of the modular prosthetic femoral head from the trunnion of the same tapered titanium stem because of fretting and wear of the Morse taper in a metal-on-polyethylene bearing. Continued clinical and scientific research on Morse taper junctions is warranted to identify and prioritize implant and surgical factors that lead to this and other types of trunnion failure to minimize complications associated with Morse taper junctions as hip implants and surgical techniques continue to evolve.

Cluster and Time-Series Analyses of Computer-Assisted Pronunciation Training Users
Authors: Nix John-Michael L.
Published: June 2014

The present study utilized hierarchical agglomerative cluster (HAC) analysis to categorize users of a popular, web-based computer-assisted pronunciation training (CAPT) program into user types using activity log data. Results indicate an optimal grouping of four types: Reluctant, Point-focused, Optimal, and Engaged. Clustering was determined by aggregate data on seven indicator variables of mixed types (e.g., ratio, continuous, and categorical). It was found that measurements of effort: lines recorded and episodic effort served best to distinguish the user types. Subsequent time-series analysis of cluster members showed that groupings exhibited distinct trends in learning behavior which explain performance outcomes. Four waves of data were collected during one semester of EFL instruction wherein CAPT usage partially fulfilled course requirements. This study follows an exploratory, data-driven approach. In addition to the findings above, suggestions for future research into interactions between individual differences variables and CALL platforms are made.

Published: June 2014

Social networks are one of the more notable sociological phenomena of the last years. Moreover, its apparition and acceptance by majority of the citizens also suppose an important challenge for the firms. Social networks are a new and relevant channel of communication and interaction with their consumers. For this, firms have to create his own place in the social network and manage of active form the content that shares and the dialogue that is supported by their followers. In the first part of this paper we explain the creation of an index to evaluate the presence of the companies in the social network more used to international level, Facebook. The Facebook Assessment Index (FAI) is formed by several indicators grouped in three dimensions: popularity, interactivity and content. The weights for each category were obtained as recommended by a Delphi study conducted with 10 independent experts (community managers and internet marketing experts). In the second part, we applied this index to the 150 largest firms according to Fortune 2011 ranking. At present, only 44% of these firms tested had an international official Facebook page. The results showed that the larger firms are those that in general terms best manage their presence on Facebook, have the greatest number of followers and a higher degree of interactivity with them. However, the most interesting contribution of this work lies not in identifying firms that achieve higher scores on the FAI, but in comparing the pages with each other and making suggestions of ideas and practices that may improve a firm's Facebook presence as a marketing tool.

Authors: Han Kyung Jung , Cho Chang-Hoan
Published: June 2014

The purpose of this study is to examine how corporations communicate with consumers in social media. For this, Twitter activities of Fortune 500 companies were content-analyzed, focusing on four factors: shared information, the method of communication, tweet contents, and tactics. The findings indicate that corporations tend to disclose their basic information mostly on their Twitter pages and mainly post organic tweets (65.9%) and corporate news (48.7%). In terms of tweeting tactics, corporations apply the “link” function to connect to their websites, blogs, or Facebook pages. Additionally, among three indexes (Fortune 500 rankings, the corporate activity score, and product group categorization) for evaluating the corporate use patterns in Twitter, the product groups categorized by the Foote, Cone, and Belding (FCB) grid model (high/low involvement and thinking/feeling) proved that the model can be applied to examine the different Twitter activities of organizations. The results of this study can help with the development of a tailored measurement tool for managing consumers, depending on the different categories of organizations and designing future plans within a social networking site (SNS).

Authors: Hu Chao Bei , Guo Bao Feng , Zhang Yong Tao , Jin Miao , Yang Guan Qiang , Ma Ming Fang
Published: June 2014

Calculation of the critical condition for the initiation of DRX is of considerable interest for the modeling of industrial processes but it strongly depends on the chemical composition of the material, the grain size prior to deformation, and the deformation conditions ( T and ε ). This paper was therefore to show an approach that allows for accurate but convenient identification of the occurrence of DRX. For a Fe-Cr-Ni super stainless steel, the results show that there is a linear relationship between σc and lnZ ( σc=457.26-12.52lnZ). In addition, within the entire range of temperature and strain rate studied, it can be found that the values of both σc and σp or εc and εp keep similar variation trends, respectively. Finally, it was found that the critical ratios of both σc/σp and εc/εp remain fairly constant (≈0.92 and ≈0.47, respectively).

Published: June 2014

In this study, the effect of scrap ratio on the mechanical and corrosion properties of Zr-1Nb-0.7Sn-0.1Fe alloy was studied. Oxygen content in the ingot cake increased rapidly with increasing fraction of scrap, which can be attributed to the surface oxide of scrap cake made of small pieces of turning, chips, etc. Iron content was not changed much, suggesting scrap materials was well reserved in the iron-free container. As-cast structure of Zr-1Nb-0.7Sn-0.1Fe alloy with the scrap:sponge ratio displayed basket-weave α phase and no appreciable change of the cast structure was observed with change of scrap fraction. The strength increases with increasing fraction of scrap, which can be attributed to the increase of oxygen content. The ductility decreased slightly with increase of scrap fraction. The increase of oxidation resistance with increasing fraction of scrap also can be linked to the increase of oxygen content.
