Radiofrequency and Its Effect on Suture Strength
Authors: Shah Anup A. , Kang Parminder , Deutsch Allen
Published: December 2009

The use of radiofrequency-based electrocautery for hemostasis and ablation within the subacromial space and glenohumeral joint can cause damage to suture material. Prior studies have focused on the mechanical properties of sutures including their ability to withstand abrasion. The purpose of this study was to determine the effect of electrical energy on the mechanical properties of 5 different brands of #2 suture used for arthroscopic shoulder repair: FiberWire (Arthrex Inc, Naples, Florida); Orthocord (DePuy Mitek, Norwood, Massachusetts); Hi-Fi (formally Herculine; Linvatec Corp, Largo, Florida); MaxBraid (Teleflex Medical, Research Triangle Park, North Carolina); and Ethibond (Ethicon, Inc, Somerville, New Jersey). A matched pair of human deltoid muscle submerged in buffered saline solution (pH 7.4) was used as a test medium.

The suture strengths were tested in 3 different scenarios. The 3 groups were as follows: control group without electrical current, coagulation group with direct introduction of electrical current on a coagulate setting for 2 seconds, and a cutting group with direct introduction of electrical current on a cut setting for 2 seconds. Hi-Fi suture seemed to be the least susceptible to damage by direct electrocautery application. Orthocord suffered the greatest loss of strength of all materials tested. This study demonstrates that exposure to electrocautery damages and weakens suture. Great care should be taken when electrocautery is used during arthroscopic repairs to prevent suture failure and preserve repair integrity.

Authors: Rossi Mark D. , Eberle Thomas , Roche Martin , Waggoner Matthew , Blake Robert , Burwell Brooke , Baxter Amy
Published: December 2009

The goal of this study was to compare outcomes during postoperative rehabilitation between individuals who delayed surgery to those who did not delay surgery. Forty-two patients who underwent unilateral total knee replacement (TKR) were categorized into 2 groups: early surgical (n=30, surgery 324 days prior) and late surgical (n=12, surgery ⩾325 days from the initial orthopedic office visit). The KSKS, KSFS, SF-12 PC summary, and AROM for knee extension and flexion were assessed preoperatively. The WOMAC, weight bearing during a 30° (SQ30) and 60° (SQ60) squat, and the Timed Up and Go were assessed at the initial visit and discharge of rehabilitation. A Mann-Whitney was used to assess for differences between groups for the WOMAC pain and physical function dimensions at the initial visit and at discharge. A 2×2 ANOVA was used to assess for differences between groups at the initial visit and at discharge for SQ30, SQ60, and Timed Up and Go. Independent t tests were used to assess for differences between groups for clinical measures taken preoperatively. Effect sizes were calculated over postoperative rehabilitation. Regardless of time, the late surgical group placed significantly less body weight on the involved side during SQ30 and took longer to complete the Timed UP and Go. The late surgical group reported greater pain at the initial visit and greater difficulty with functional activities at the initial visit and discharge. Change scores were similar in both groups and effect sizes were moderate to high. Individuals who delayed surgery, for whatever reason, did not perform at levels of their counterparts who had shorter waiting times.
Study on the Impact of Morselized Bones on Biological Binding of HA-coated Femoral Stem in Dogs
Authors: Song Ke-guan , MA De-sheng , Cheng Cheng-Kung , Yan Jing-Long
Published: December 2009

The impact of the dog's morselized autologous bone implantation into femoral medullary cavity on binding in the hydroxyapatite-coated femoral stem prosthesis–bone interface was studied. Twenty-four adult mongrel dogs were divided into 2 groups: experimental and control. The experimental group's medullary cavity was filled with morselized autologous bone. Artificial femoral-stem replacements at the right side were then carried out. At 1, 3, and 6 months postoperatively, computed tomography (CT) values reflecting changes in bone density were measured. A histological observation to check prosthesis–bone interface contact ratios and bone growth was conducted. Analysis of radiographs of slices was made using Interactive Data Language (IDL; ITT Visual Information Solutions, Boulder, Colorado) software. Results showed that the experimental group fared better than the control group, and the difference was statistically significant (
P
<.05). Stereomicroscope-based observation showed that the number of trabecular bones in the experimental group was larger than that of the control group, and bone growth of the experimental group was also better than that of the control group. Inverted microscope observation showed that the binding degree between prosthesis and trabecular bone of the experimental group was higher than that of the control group. Comparatively, the experimental group's trabecular bone had more osteogenic cells. The binding between morselized autologous bone and hydroxyapatite-coated femoral stem prosthesis can improve direct bone-contact ratios, and the experimental group's number of newly formed trabecular bone was significantly larger than that of the control group.
Management of the Second and Third Metatarsal in Moderate and Severe Hallux Valgus
Authors: Wang Xu , Jiang Jian-Yuan , MA Xin , Huang Jia-Zhang , Gu Xiang-Jie
Published: December 2009

Hallux valgus is a common disorder of the forefoot that results from medial deviation of the first metatarsal and lateral deviation and/or rotation of the great. The management of hallux valgus is usually focused on the malalignment of the first ray, however, some patients report that pain at the plantar aspect of second and/or third metatarsal head(s) is more severe than the first metatarsophalangeal joint. In order to alleviate the metatarsalgia, we developed an oblique sliding osteotomy to manage the second metatarsal. This article reports the results of 17 feet that were treated with oblique sliding osteotomy. Average patient age was 55.3 years. The transverse arch of all patients had sagged, and all patients had painful calluses below the lesser metatarsals. Functional outcome was evaluated with the hallux valgus angle, intermetatarsal angle, proximal articular and distal articular set angles, and American Orthopaedic Foot and Ankle Society scoring system. The mean hallux valgus angle was 37.6° preoperatively and 13.2° postoperatively (mean correction, 24.4°) and the mean intermetatarsal angle was 14.6° preoperatively and 6.8° postoperatively (mean correction, 8.8°). American Orthopaedic Foot and Ankle Society scores improved from an average of 58 preoperatively to 87 postoperatively. Based on appearance and function, the outcomes of 16 feet were satisfactory. Pain of the forefoot was ameliorated and Mielke scores of 14 feet were either very good or good (82.3%) and satisfactory for 2 feet. Final follow-up was an average of 16 months and all patients were ambulating normally. We thus conclude that this surgical technique is effective in patients with moderate or severe hallux valgus.
Intrathoracic Fracture–Dislocation of the Proximal Humerus Treated With Reverse Total Shoulder Arthroplasty
Authors: Maroney Samuel S. , Devinney D. Scott
Published: December 2009

High-energy trauma to the shoulder can lead to complex fractures and dislocations that challenge even the most experienced orthopedic surgeon's reconstructive capabilities. One such injury is a fracture–dislocation of the proximal humerus, in which the humeral head becomes impaled in the thoracic cavity.

This article presents a case of a 67-year-old woman who sustained an intrathoracic fracture–dislocation of the proximal humerus after a fall down a flight of stairs. After emergent extrication of the intrathoracic humeral head and proximal medial shaft, the patient underwent delayed shoulder reconstruction with a reverse total shoulder arthroplasty and allograft augmentation. The reverse shoulder was used due to the high-energy comminution, stripping of the remaining tuberosity fragments, and extensive proximal bone loss. The patient's functional ability would therefore depend on the biomechanical design of the prosthesis and not solid healing of the severely compromised tuberosity pieces. The proximal shaft was reconstructed using a femoral strut allograft that was cabled into place. This was done to restore the medial humeral calcar that was missing due to her injury. The shoulder was then reconstructed using the Reverse Shoulder Prosthesis (Encore Medical, Austin, Texas).

This is the first description of the reverse total shoulder used for intrathoracic fracture–dislocation of the proximal humerus. The reverse total shoulder arthroplasty is a viable option to treat complicated proximal humerus trauma in the appropriately selected patient.
Unusual Radiographic Appearance of Adamantinoma
Authors: Cappuccio Michele , Montalti Maurizio , Bosco Giuseppe , Gasbarrini Alessandro , Boriani Stefano
Published: December 2009

Adamantinoma is a rare tumor with an indolent course that occurs most commonly in the tibia. It is locally aggressive, and local recurrences are described after resection. Pain is the most common symptom. Since the lesion is typically slow growing, the pain can be present for many years before the patient seeks medical attention. Microscopically, adamantinoma consists of islands of epithelial cells in a fibrous stroma. Nuclear atypia is minimal, and mitotic figures are rare. The most common radiographic appearance is that of multiple sharply demarcated radiolucent lesions surrounded by areas of dense, sclerotic bone. This tumor most often affects the tibial diaphysis and produces lytic lesions that can cause fractures.

A 31-year-old man presented with a rapidly growing lytic lesion of the distal tibia. On histological examination, many areas of epithelial cells in a fibrous stroma were identified. Diagnosis of adamantinoma was performed. The lesion was treated with en bloc resection and reconstruction with distal tibia allograft and ankle arthrodesis with retrograde nail. At 2-year follow-up, there were no clinical or radiological signs of recurrence of disease.

Published: December 2009

Peroneal nerve palsy has been reported in association with traumatic and nontraumatic causes. We encountered a 75-year-old man whose peroneal nerve palsy developed suddenly following varus deformity of the arthritic knee. A review of the literature found 1 other report describing a progressive peroneal nerve palsy associated with a varus deformity of the knee due to arthritis.

Our patient had progressive intractable knee pain; 3-compartment, severe degenerative changes in the knees; varus knee malalignment and laxity; right peroneal nerve palsy; and decreased sensation to light touch and pinprick on the dorsum of the right foot. The preoperative WOMAC score was 36. Nerve conduction studies confirmed acute peroneal neuropathy with conduction block at the fibular neck and secondary axonal degeneration. Magnetic resonance imaging of the knee showed osteophytes and cysts surrounding the fibular neck. Although their compression could be responsible for the nerve palsy, the sudden process made this less possible. Thus, the patient underwent total knee arthroplasty of both knees without exploration of the nerve. At 5-month follow-up, the WOMAC score was 78. The patient walked with a cane with no varus thrust, and his right knee had no varus laxity in full extension. The peroneal nerve did not retain its function. Sensory examination and postoperative nerve conduction studies showed no improvement.
Factors affecting shapers of organizational wikis
Authors: Yates Dave , Wagner Christian , Majchrzak Ann
Published: December 2009

New Web 2.0 technologies such as wikis permit any organizational member of a virtual community of practice (CoP) to dynamically edit, integrate, and rewrite content (what we call knowledge shaping) as well as contribute personal knowledge. Previous research on factors that motivate contribution in virtual CoPs has focused exclusively on factors explaining why people contribute their personal knowledge, with no research focused on why people make the knowledge‐shaping contributions (rewriting, integrating, and restructuring pages) which are possible with wikis. We hypothesize that factors that explain frequency of contribution will be different for those who shape from those who contribute only their personal knowledge. The results support our hypotheses. In addition, we find that shapers are not more likely to be managers or members of a community's core group who might typically serve in an administrator role, contrary to prior expectations. The implications of using Web 2.0 tools to encourage this shaping behavior are discussed.
Present and future development in plastics from biomass
Authors: Shen Li , Worrell Ernst , Patel Martin
Published: December 2009

Biobased plastics have experienced fast growth in the past decade thanks to the public concerns over the environment, climate change and the depletion of fossil fuels. This perspective provides an overview of the current global market of biobased plastics, their material properties, technical substitution potential and future market (for 2020). In addition, the technology and market development of three biobased plastics, namely polylactide (PLA), biobased polyethylene (PE) and biobased epoxy resin, are discussed in detail. The emerging biobased plastics market is still small compared to traditional biobased polymers and biomaterials. The global capacity of the emerging biobased plastics was only 0.36 million tonnes in 2007. However, the market grew strongly between 2003 and 2007 (approx. 40% per year). The technical substitution potential of biobased plastics replacing petrochemical plastics is estimated at 90%, demonstrating the enormous potential of biobased plastics. Global capacity of biobased plastics is expected to reach 3.45 million metric tonnes in 2020. Starch plastics, PLA, biobased PE, polyhydroxyalkanoates (PHA) and biobased epoxy resin are expected to be the major types of biobased plastics in the future.

The effect of isolated lignins, obtained from a range of pretreated lignocellulosic substrates, on enzymatic hydrolysis
Authors: Nakagame Seiji , Chandra Richard P. , Saddler Jack N.
Published: December 2009

The influence of the residual lignin remaining in the cellulosic rich component of pretreated lignocellulosic substrates on subsequent enzymatic hydrolysis was assessed. Twelve lignin preparations were isolated by two isolation methods (protease treated lignin (PTL) and cellulolytic enzymatic lignin (CEL)) from three types of biomass (corn stover, poplar, and lodgepole pine) that had been pretreated by two processes (steam and organosolv pretreatments). Comparative analysis of the isolated lignin showed that the CEL contained lower amounts of carbohydrates and protein than did the PTL and that the isolated lignin from corn stover contained more carbohydrates than did the lignin derived from the poplar and lodgepole pine. The lower yields of acid insoluble lignin (AIL) obtained from the corn stover when using the PTL method indicated that the lignin from the corn stover had a higher hydrophilicity than did the lignin from the poplar and lodgepole pine. The isolated lignin preparations were added to the reaction mixture containing crystalline cellulose (Avicel) and their possible effects on enzymatic hydrolysis were assessed. It was apparent that the lignin isolated from lodgepole pine and steam pretreated poplar decreased the hydrolysis yields of Avicel, whereas the other isolated lignins did not appear to decrease the hydrolysis yields significantly. The hydrolysis yields of the pretreated lignocellulose and those of Avicel containing the PTL showed good correlation, indicating that the nature of the residual lignin obtained after pretreatment significantly influenced hydrolysis.

Production of biocommodities and bioelectricity by cell‐free synthetic enzymatic pathway biotransformations: Challenges and opportunities
Authors: Zhang Y.‐H. Percival
Published: December 2009

Cell‐free synthetic (enzymatic) pathway biotransformation (SyPaB) is the assembly of a number of purified enzymes (usually more than 10) and coenzymes for the production of desired products through complicated biochemical reaction networks that a single enzyme cannot do. Cell‐free SyPaB, as compared to microbial fermentation, has several distinctive advantages, such as high product yield, great engineering flexibility, high product titer, and fast reaction rate. Biocommodities (e.g., ethanol, hydrogen, and butanol) are low‐value products where costs of feedstock carbohydrates often account for ∼30–70% of the prices of the products. Therefore, yield of biocommodities is the most important cost factor, and the lowest yields of profitable biofuels are estimated to be ca. 70% of the theoretical yields of sugar‐to‐biofuels based on sugar prices of ca. US$ 0.18 per kg. The opinion that SyPaB is too costly for producing low‐value biocommodities are mainly attributed to the lack of stable standardized building blocks (e.g., enzymes or their complexes), costly labile coenzymes, and replenishment of enzymes and coenzymes. In this perspective, I propose design principles for SyPaB, present several SyPaB examples for generating hydrogen, alcohols, and electricity, and analyze the advantages and limitations of SyPaB. The economical analyses clearly suggest that developments in stable enzymes or their complexes as standardized parts, efficient coenzyme recycling, and use of low‐cost and more stable biomimetic coenzyme analogs, would result in much lower production costs than do microbial fermentations because the stabilized enzymes have more than 3 orders of magnitude higher weight‐based total turn‐over numbers than microbial biocatalysts, although extra costs for enzyme purification and stabilization are spent.

Prolonged stimulus exposure reveals prolonged neurobehavioral response patterns

Published: December 2009

Although it has been shown repeatedly that minimum response times in sensory systems can be quite short, organisms more often continue to respond to sensory stimuli over considerably longer periods of time. The continuing response to sensory stimulation may be a more realistic assessment of natural sensory responses, so we determined for how long a stimulus would evoke a response in naïve, freely moving animals. Specifically, we determined for how long such rats responded to odorants during continuous passive exposures by monitoring their sniffing with whole‐body plethysmography. We found that naïve rats continue to sniff odorants vigorously for up to 3 minutes, much longer than what has been reported for highly trained, highly motivated rats. Patterns of 2‐deoxyglucose (2‐DG) uptake in the glomerular layer of the rat olfactory bulb also were seen after only 1–5 minutes of odorant exposure, overlapping with the period of increased respiration to odorants. Moreover, these 2‐DG uptake patterns closely resembled the patterns that emerge from prolonged odorant exposures, suggesting that activity mapping over prolonged periods can identify areas of activity that are present when rats are still attending and responding to odorant stimuli. Given these findings, it seems important to consider the possibility that prolonged exposure to other sensory stimuli will reveal more realistic neural response patterns. J. Comp.

A novel approach to user data federation in Next‐Generation Networks
Authors: Bartolomeo Giovanni , Kovacikova Tatiana , Petersen Françoise
Published: December 2009

User Profile Management (UPM) is an essential feature to support applications in Next‐Generation Network (NGN). Its actual realization depends on standardization of information and preferences and the ways in which user data are expressed and handled. To this end, an NGN may support different approaches; among them, the ‘federated approach’ seems particularly relevant, as it fits the very common scenario in which many existing services and devices already contain specific settings and preferences that are however unrelated to any other. This paper proposes a novel, totally distributed solution for data federation, where authorization, management of data localization and synchronization of federated data are thought to be part of the meta information that may be associated with each data element, rather than being external resources or built‐in functions, as in legacy solutions. First, the present paper introduces the work on personalization and UPM and the NGN architecture being done at ETSI. Then, the paper illustratesthe work on user data interoperability performed at OASIS XDI TC. Finally, based on these inputs, it explains how to combine them into a novel solution (which is not part of ETSI or OASIS specifications). Copyright © 2009 John Wiley & Sons, Ltd.
