Handedness is perhaps the most studied human asymmetry. Laterality is the preference shown for one side and it has been studied in many aspects of medicine. Studies have shown that some orthopaedic procedures had poorer outcomes and identified laterality as a contributing factor. We developed a questionnaire to assess laterality in orthopaedic surgery and compared this to an established scoring system. Sixty-two orthopaedic surgeons surveyed with the validated Waterloo Handedness Questionnaire (WHQ) were compared with the self developed Orthopaedic Handedness Questionnaire (OHQ). Fifty-eight were found to be right hand dominant (RHD) and 4 left hand dominant (LHD). In RHD surgeons, the average WHQ score was 44.9% and OHQ 15%. For LHD surgeons the WHQ score was 30.2% and OHQ 9.4%. This represents a significant amount of time using the non dominant hand but does not necessarily determine satisfactory or successful dexterity transferable to the operating room. Training may be required for the non dominant side.

Burnout is a syndrome marked by emotional exhaustion, depersonalization, and low job satisfaction. Rates of burnout in orthopaedic surgeons are higher than those in the general population and many other medical subspecialties. Half of all orthopaedic surgeons show symptoms of burnout, with the highest rates reported in residents and orthopaedic department chairpersons. This syndrome is associated with poor outcomes for surgeons, institutions, and patients. Validated instruments exist to objectively diagnose burnout, although family members and colleagues should be aware of early warning signs and risk factors, such as irritability, withdrawal, and failing relationships at work and home. Emerging evidence indicates that mindfulness-based interventions or educational programs combined with meditation may be effective treatment options. Orthopaedic residency programs, departments, and practices should focus on identifying the signs of burnout and implementing prevention and treatment programs that have been shown to mitigate symptoms.

Plastering is one of the most ancient of the building handicrafts. Plaster is the common name for calcium sulphate hemi hydrate made by heating the mineral gypsum, the common name for sulphate of lime. In the tenth century the Arabs used liquid plaster in orthopaedic treatment. At the beginning of the nineteenth century, patients with fractures of the lower extremities-and often of the upper extremities as well-were treated in bed with restriction of all activity for many weeks until the fractures united. It was the practice of surgeons to dress wounds and fractures at frequent intervals. The bandages, pads, and splints were removed, the fractures manipulated, and the dressings reapplied. The search for simpler, less cumbersome methods of treatment led to the development of occlusive dressings, stiffened at first with starch and later with plaster of Paris. The ambulatory treatment of fractures was the direct result of these innovations. Two military surgeons, Antonius Mathijsen of the Netherlands, and Nikolai Ivanovitch Pirogov of Russia, were responsible for the introduction of the new plaster bandage technique. At the beginning of the twentieth century the technique was improved by Jean-François Calot, a French surgeon, who invented the hand manufacture of plaster bandage as a roll. During the twentieth century, walking cast and ambulation for fresh fractures were developed with plaster and pin incorporated in plaster; the open fracture care concept was introduced with plaster of Paris by Trueta before the external fixation.

Full Text Available Abstract Background The ongoing process of population aging is associated with an increase in prevalence of musculoskeletal conditions with a concomitant increase in the demand of orthopaedic services. Shortages of orthopaedic services have been documented in Canada and elsewhere. This population-based study describes the number of patients seen by orthopaedic surgeons in office and hospital settings to set the scene for the development of strategies that could maximize the availability of orthopaedic resources. Methods Administrative data from the Ontario Health Insurance Plan and Canadian Institute for Health Information hospital separation databases for the 2005/06 fiscal year were used to identify individuals accessing orthopaedic services in Ontario, Canada. The number of patients with encounters with orthopaedic surgeons, the number of encounters and the number of surgeries carried out by orthopaedic surgeons were estimated according to condition groups, service location, patient's age and sex. Results In 2005/06, over 520,000 Ontarians (41 per 1,000 population had over 1.3 million encounters with orthopaedic surgeons. Of those 86% were ambulatory encounters and 14% were in hospital encounters. The majority of ambulatory encounters were for an injury or related condition (44% followed by arthritis and related conditions (37%. Osteoarthritis accounted for 16% of all ambulatory encounters. Orthopaedic surgeons carried out over 140,000 surgeries in 2005/06: joint replacement accounted for 25% of all orthopaedic surgeries, whereas closed repair accounted for 16% and reductions accounted for 21%. Half of the orthopaedic surgeries were for arthritis and related conditions. Conclusion The large volume of ambulatory care points to the significant contribution of orthopaedic surgeons to the medical management of chronic musculoskeletal conditions including arthritis and injuries. The findings highlight that surgery is only one component of the work
We monitored the amount of radiation received by surgeons and assistants during surgery carried out with fluoroscopic assistance. The radiation was monitored with the use of MYDOSE MINIX PDM107 made by Aloka Co. Over a one year period from Aug 20, 1992 to Aug 19, 1993, a study was undertaken to evaluate exposure of the groin level to radiation with or without use of the lead apron during 106 operation (Group-1). In another group, radiation was monitored at the breast and groin level outside of the lead apron during 39 operations (Group-2). In Group-1, the average exposure per person during one year was 46.0 μSV and the average exposure for each procedure was 1.68 μSV. The use of the lead apron affirmed its protective value; the average radiation dose at the groin level out-side of the apron was 9.11 μSV, the measured dose beneath the apron 0.61 μSV. The average dose of exposure to the head, breast at groin level outside of the lead apron, were 7.68 μSV, 16.24 μSV, 32.04 μSV respectively. This study and review of the literature indicate that the total amount of radiation exposure during surgery done with fluoroscopic control remains well within maximum exposure limits. (author)

Full Text Available Abstract Background There is increasing interest by chiropractors in North America regarding integration into mainstream healthcare; however, there is limited information about attitudes towards the profession among conventional healthcare providers, including orthopaedic surgeons. Methods We administered a 43-item cross-sectional survey to 1000 Canadian and American orthopaedic surgeons that inquired about demographic variables and their attitudes towards chiropractic. Our survey included an option for respondants to include written comments, and our present analysis is restricted to these comments. Two reviewers, independantly and in duplicate, coded all written comments using thematic analysis. Results 487 surgeons completed the survey (response rate 49%, and 174 provided written comments. Our analysis revealed 8 themes and 24 sub-themes represented in surgeons' comments. Reported themes were: variability amongst chiropractors (n = 55; concerns with chiropractic treatment (n = 54; areas where chiropractic is perceived as effective (n = 43; unethical behavior (n = 43; patient interaction (n = 36; the scientific basis of chiropractic (n = 26; personal experiences with chiropractic (n = 21; and chiropractic training (n = 18. Common sub-themes endorsed by surgeon's were diversity within the chiropractic profession as a barrier to increased interprofessional collaboration, endorsement for chiropractic treatment of musculoskeletal complaints, criticism for treatment of non-musculoskeletal complaints, and concern over whether chiropractic care was evidence-based. Conclusions Our analysis identified a number of issues that will have to be considered by the chiropractic profession as part of its efforts to further integrate chiropractic into mainstream healthcare.

PURPOSE. To investigate consultant surgeons' knowledge about the costs of implants for various joint surgeries. METHODS. Questionnaires were distributed to consultant orthopaedic surgeons at 2 hospitals. Respondents were asked to estimate the implant costs of any brand for low-demand and high-demand total hip replacement (THR), total knee replacement (TKR), uni-compartmental knee replacement, arthroscopy shaver blade, total anterior cruciate ligament (ACL) fixation, and meniscal repair. The actual cost of each implant was obtained from the manufacturer. RESULTS. 16 consultant surgeons completed the questionnaires. The respective mean estimated and actual costs for a low-demand THR implant were £1714 (range, £600-3000) and £1448 (range, £985- 2335), with an overestimation of 18.4%. The respective costs for a high-demand THR implant were £2172 (range, £600-6000) and £1737 (range, £1192-2335), with an overestimation of 25%. The respective costs for a TKR implant were £1550 (range, £600-6000) and £1316 (range, £995-1535), with an overestimation of 17.8%. The respective costs for a uni-compartmental knee replacement implant were £1040 (range, £600-2000) and £1296 (range, £698-1470), with an underestimation of 19.7%. The respective costs for an arthroscopy shaver blade were £110 (range, £75-150) and £94 (range, £80-100), with an overestimation of 16.6%. The respective costs for a total ACL fixation implant were £246 (range, £80-500) and £306 (range, £272-335), with an underestimation of 19.4%. The respective costs for a meniscal repair implant were £153 (range, £50-250) and £242 (range, £170-260), with an underestimation of 37%. CONCLUSION. The knowledge among consultant orthopaedic surgeons about implant costs was poor. To reduce implant costs, cooperation between surgeons and hospital managers and measures to increase surgeons' awareness about cost-reduction programmes are needed. PMID:25163960

We as plastic surgeons are engrossed and consumed by our quest to optimize patient care. In so doing, we are often distracted by that aspect of our practice which has direct bearing on patient care yet for which we are the least prepared--the business aspect. The entire population of Canadian plastic surgeons was surveyed in an effort to establish real and perceived needs of this group with respect to the business management of their practices. The survey elicited demographic information, information on business educational background, interest, and current commitment in acquiring business knowledge, and a final category of questions dealing with how well these surgeons function as business managers. Of the 315 plastic surgeons surveyed, 122 (39 percent) responded, which, in and of itself, indicates an interest in this aspect of their practices. Twelve respondents were excluded from the study for various reasons. Eighty of the 110 remaining respondents (72 percent) used a hospital-integrated facility for both emergency and elective outpatient procedures. Eighty-four of the 110 respondents (76 percent) indicated that 10 percent of their hours per week of inpatient booked operating time was canceled. Ninety-three percent of respondents felt that a business course to familiarize surgeons with common business situations and areas of personal finance would be beneficial. Few were previously educated in business, and similarly, few had great ongoing interest in business, although the majority of respondents used publications specifically dealing with financial matters (provided by the Canadian Medical Association). Twenty-three percent of respondents saw themselves in a growing role as businesspeople; 24 percent felt this dual role was enjoyable, while 29 percent felt this role was forced on them. A total of 21 percent of respondents did not see themselves as businesspeople at all. The six basic functions of a manager (planning, acquiring, organizing, actuating
In Japan, the treatment of soft tissue sarcomas (STS) has been performed mainly by orthopaedic surgeons. The standard therapy for all cases of STS is surgical resection of the tumor. The prognosis of patients with unresectable tumors or distant metastases is poor despite treatment with intensive chemotherapy. Adjuvant chemotherapy is indicated for patients with resectable tumors. Round-cell STS, including extraskeletal Ewing sarcoma and rhabdomyosarcoma, have high sensitivity to chemotherapy. The standard treatment for round-cell STS is multimodal therapy with surgery and chemotherapy, with or without radiotherapy. On the other hand, non-round cell STS, including leiomyosarcoma, synovial sarcoma, and liposarcoma, have low sensitivity to chemotherapy. Thus, the standard treatment for non-round cell STS is essentially, surgery. Large and high-grade non-round cell STS are also treated using adjuvant chemotherapy along with surgery. In this review, the standard therapies for STS and the future perspective in Japan are discussed. PMID:26809525

The aim of the present study was to assess the radiation dose to the eye lens of orthopaedic surgeons during various orthopaedic procedures and to make efforts to ensure that radiation protection is optimised. The study was performed for Fractura femoris and Fractura cruris procedures performed in orthopaedic operating theatres, as well as for fractures of wrist, ankle and hand/shoulder performed in the emergency trauma room. The highest mean value of the eye lens dose of 47.2 μSv and higher mean fluoroscopy time of 3 min, as well as the corresponding highest maximum values of 77.1 μSv and 5.0 min were observed for the Fractura femoris procedure performed with the Biplanar 500e fluoroscopy systems. At a normal workload, the estimated mean annual dose values do not exceed the annual occupational dose limit for the lens of eye, but at a heavy workload in the department, this dose limit could be achieved or exceeded. The use of protective lead glasses is recommended as they could reduce the radiation exposure of the lens of the eye. The phantom measurements demonstrated that the use of half-dose mode could additionally reduce dose to the operator's eye lens. PMID:25944961

Richard von Volkman was one of the most famous and important surgeons in the 19th century. He pioneered antiseptic procedures and was especially known for his achivements in orthopedic surgery. Von Volkmann was born in Leipzig, Germany and attended medical schools in Giessen, Halle, and Berlin. Starting in 1867, he worked as a professor of surgery at the University of Halle, also leading its surgical clinic. He was active as a surgeon during Seven Weeks' War with Austria in 1866 and the Franco-Prussian war 1870/1871, in the latter as consulting Generalarzt. He was important in the introduction of antiseptic wound treatment in Germany, and through it to the United States of America. Two observations in orthopaedic surgery bear his name to these days: Volkmans contracture and Heuter-Volkmans low. Volkmann also wrote poetry under the name Richard Leander and his book entitled "Dreams by French Firesides" which still has a place in literature. He died of paralysis due to a chronic spinal disease, following a prolonged illness, in the Binswanger institution in Jena in 1889, at the top of his careere. PMID:20954309

Background Manufacturers of implants and materials in the field of orthopaedics use significant amounts of funding to produce informational material to influence the decision-making process of orthopaedic surgeons with regards to choice between novel implants and techniques. It remains unclear how far orthopaedic surgeons are really influenced by the materials supplied by companies or whether other, evidence-based publications have a higher impact on their decision-making. The objective was to evaluate the subjective usefulness and usage of different sources of information upon which orthopaedic surgeons base their decisions when acquiring new implants or techniques. Methods We undertook an online survey of 1174 orthopaedic surgeons worldwide (of whom n = 305 were head of their department). The questionnaire included 34 items. Sequences were randomized to reduce possible bias. Questions were closed or semi-open with single or multiple answers. The usage and relevance of different sources of information when learning about and selecting orthopaedic treatments were evaluated. Orthopaedic surgeons and trainees were targeted, and were only allowed to respond once over a period of two weeks. Baseline information included country of workplace, level of experience and orthopaedic subspecialisation. The results were statistically evaluated. Results Independent scientific proof had the highest influence on decisions for treatment while OEM (Original Equipment Manufacturer) driven activities like newsletters, white papers or workshops had the least impact. Comparison of answers from the three best-represented countries in this study (Germany, UK and USA) showed some significant differences: Scientific literature and congresses are significantly more important in the US than in the UK or Germany, although they are very important in all countries. Conclusions Independent and peer-reviewed sources of information are preferred by surgeons when choosing between methods and

The financial realities of providing trauma care to injured patients can make it difficult to produce an accurate assessment of the cumulative value orthopaedic trauma surgeons provide to healthcare and university institutions. As with many political battles in the field of medicine, physicians who have been diligently focused on providing patient care were completely unaware of the impending upheaval around them. Whether orthopaedic trauma surgeons are employed or in some type of partnership with hospitals, too often surgeons find the relationship one-sided. In order to effectively negotiate with hospitals, surgeons must demonstrate the comprehensive value they provide to their respective healthcare institutions and universities. Orthopaedic trauma surgeons make direct and indirect financial contributions to the hospital in addition to educational and community services. The sum total of these valued contributions helps fund non-revenue generating programs, provides marketing opportunities, and improves the regional and national reputation of the healthcare institution. This paper provides a comprehensive review of the value contributed to healthcare institutions by orthopaedic trauma surgeons and will serve as a blueprint for all surgeons to accurately account for and demonstrate their value to hospitals while providing efficient and compassionate care to our patients.

Barriers to successful innovation can be identified and potentially addressed by exploring the perspectives of key stakeholders in the innovation process. Cardiac surgeons in Canada were surveyed for personal perspectives on biomedical innovation. Quantitative data was obtained by questionnaire and qualitative data via interviews with selected survey participants. Surgeons were asked to self-identify into 1 of 3 categories: "innovator," "early adopter," or "late adopter," and data were compared between groups. Most surgeons viewed innovation favourably and this effect was consistent irrespective of perceived level of innovativeness. Key barriers to the innovation pathway were identified: (1) support from colleagues and institutions; (2) Canada's health system; (3) sufficient investment capital; and (4) the culture of innovation within the local environment. Knowledge of the innovation process was perceived differently based on self-reported innovativeness. The majority of surgeons did not perceive themselves as having the necessary knowledge and skills to effectively translate innovative ideas to clinical practice. In general, responses indicate support for implementation of leadership and training programs focusing on the innovation process in an effort to prepare surgeons and enhance their ability to successfully innovate and translate new therapies. The perspectives of cardiac surgeons provide an intriguing portal into the challenges and opportunities for healthcare innovation in Canada. PMID:22902159

Fragility fractures are the most prevalent trauma condition that orthopaedic surgeons face today. Osteoporosis and susceptibility to falls are the key predisposing factors. Despite evidence supporting the impact of treating osteoporosis on reducing the incidence of fragility fractures, it is often left untreated. Orthopaedic surgeons are often the first physicians to assess and treat the patient after a fragility fracture. Their role therefore does not end in the skillful fixation of the fractures, but they have a unique opportunity to ensure that preventive measures are implemented. This includes falls prevention, investigation of possible causes underlying osteoporosis, attention to diet, exercise, calcium, and vitamin D supplementation as well as prescription of anti-resorptive and anabolic medication. The need for a dedicated multidisciplinary team needs to be emphasized and therefore effective communication between the different parties is of paramount importance. PMID:21566474

Objective The orthopedic community is in a unique position to initiate and provide osteoporosis care in fragility fracture patients to prevent future hip fractures in a high-risk population. The attitudes and intentions of Canadian orthopedic surgeons in the domain of osteoporosis care are unknown. Our objective was to identify current attitudes and osteoporosis management practices and to determine their overall willingness to participate in osteoporosis care for fragility fracture patients. Methods A real-time interactive polling session was conducted at the 58th Annual Meeting of the Canadian Orthopaedic Association. Results Of the orthopedic surgeons who responded, 90.4% agreed that the current emphasis on osteoporosis in orthopedic practice is appropriate; 85.2% of surgeons indicated that they currently refer or personally investigate for osteoporosis, or both, in fragility fracture patients. Conclusion Most of the Canadian orthopedic surgeons sampled consider themselves to be currently engaged or ready to engage in osteoporosis care for fragility fracture patients. Focus should now shift from education and persuasion to program support through provision of resources and system modification that will enable Canadian orthopedic surgeons to effectively manage osteoporosis in their fracture patients.

Full Text Available BACKGROUND: This population-based cohort study has the objective to understand the sociodemographic characteristics and health conditions of patients who do not receive surgery within 18 months following an ambulatory visit to an orthopaedic surgeon. METHODS: Administrative healthcare databases in Ontario, Canada were linked to identify all patients making an initial ambulatory visit to orthopaedic surgeons between October 1(st, 2004 and September 30(th, 2005. Logistic regression was used to examine predictors of not receiving surgery within 18 months. RESULTS: Of the 477,945 patients in the cohort 49% visited orthopaedic surgeons for injury, and 24% for arthritis. Overall, 79.3% did not receive surgery within 18 months of the initial visit, which varied somewhat by diagnosis at first visit (84.5% for injury and 73.0% for arthritis with highest proportions in the 0-24 and 25-44 age groups. The distribution by income quintile of patients visiting was skewed towards higher incomes. Regression analysis for each diagnostic group showed that younger patients were significantly more likely to be non-surgical than those aged 65+ years (age 0-24: OR 3.45 95%CI 3.33-3.57; age 25-44: OR 1.30 95%CI 1.27-1.33. The odds of not getting surgery were significantly higher for women than men for injury and other conditions; the opposite was true for arthritis and bone conditions. CONCLUSION: A substantial proportion of referrals were for expert diagnosis or advice on management and treatment. The findings also suggest socioeconomic inequalities in access to orthopaedic care. Further research is needed to investigate whether the high caseload of non-surgical cases affects waiting times to see a surgeon. This paper contributes to the development of evidence-based strategies to streamline access to surgery, and to develop models of care for non-surgical patients to optimize the use of scarce orthopaedic surgeon resources and to enhance the management of
In this study, a mathematical method was used to estimate the entrance surface dose (ESD) to the patient and the scattered dose (Ds) to the operating surgeon during various fluoroscopically guided surgical orthopaedic procedures. For 204 patients, the procedure type, the fluoroscopy time and the highest tube potential and current values observed during fluoroscopy were recorded. For the most often performed procedures (intramedullary nailing of peritrochanteric fractures, open reduction and internal fixation of malleolar fractures and intramedullary nailing of diaphyseal fractures of the femur), the respective mean fluoroscopy times were 3.2, 1.5 and 6.3 min while the estimated mean ESDs were 183, 21 and 331 mGy, respectively. The estimated Ds rates for the hands, chest, thyroid, eyes, gonads and legs of the operating surgeon were on average to 0.103, 0.023, 0.013, 0.012, 0.066 and 0.045 mGy min-1, respectively, and compare well with the literature. The mathematical estimation of doses cannot replace actual measurements; however, it can be used for a preliminary assessment of the radiation dose levels during various surgical procedures, so that the operator, the surgeon and the rest of the medical staff involved could be aware of the associated radiation risk and the radiation protection measures required.

This article outlines some of the key concepts in leadership (both styles and theories) to provide a platform for further learning and to help the modern day orthopaedic surgeons to apply these concepts to their current practice. It is focused on two major aspects: management of medical organizations and effective twenty-first century care by surgeons through proper leadership guide and aimed in improving patient care outcomes. Practicing proper leadership skills based on evidence resulted in effective management of organization. Thus achieving patient's satisfaction. PMID:26208560
In this study, radiation exposure to the surgeon and supporting staff from a mini C-arm unit during fluoroscopically guided orthopaedic surgeries was studied. A Diadose dosemeter and Gamma-Scout meter were used for air-kerma measurements for primary and scattered radiations. The entrance dose of hands, eyes and thyroid of the surgeon was measured during direct observation. Scattered air-kerma rate was measured to quantify the received entrance dose of the supporting staff. During direct observation, the skin-entrance exposure rates of the surgeon's hand, eye and thyroid gland were 8036, 0.85 and 0.9 μGy min-1, respectively. The scattered exposure rate was precipitously dropped beyond the path of the primary radiation beam, and reached 0.51 μGy min-1 at a distance of 40 cm from the beam's central axis. This study showed that the surgeon's hand was the most dose-limiting organ for fluoroscopically guided orthopaedic surgery procedures when it was exposed to primary radiation. The exposure of supporting staff at a working distance of >20 cm from the beam was minimal during fluoroscopy by mini C-arm unit. (authors)

The purpose of our study was to summarize all the knowledge concerning the innovative pioneer in the field of orthopaedic surgery, Nicholas J. Giannestras (1908-1978). A thorough study of texts, medical books and reports, in the field of history of medicine, together with a review of the available literature in PubMed, was undertaken. Giannestras left his mark in the history of orthopaedics with his clinical work and his publications, mainly his treatise "Foot Disorders: Medical and Surgical Management" (1973), while his name lingers in Greece with the introduction of spine fusion with the use of metallic implants. He was an eminent university clinical professor of orthopaedics who had harmonically combined academic writing, teaching and clinical research in every field of orthopaedic surgery. PMID:26255057

Full Text Available Abstract Background Induction programme for trainee doctors in the UK generally do not focus on the surgical aspects of their jobs. In this context we decided to conduct a telephonic survey among the hospitals belonging to three orthopaedic training regions in the UK from the point of view of the diversity of instrumentations and implants used for index procedures. Results We chose four index trauma & orthopaedic procedures (Total hip replacement, total knee replacement, intramedullary nailing and external fixator systems for long bone fractures. A telephonic survey was done in six NHS trust hospitals which were part of an orthopaedic training rotation (2 from England, 2 from Wales and 2 from Scotland. In total there were 39 different instrumentation systems for these 4 index procedures in the 6 trusts (see table 1. These comprise 12 Total hip replacement (THR systems, 14 total knee replacement (TKR systems, 9 intra-medullary nailing systems, and 4 external fixator systems. The number of different systems for each trust ranged from 7 to 19. There is a vast array of implants and instrumentation systems in each trust, as highlighted by our survey. The surgical tools are not the same in each hospitals. This situation is more complicated when trainees move to new hospitals as part of training rotations.

There have been many advances in the resuscitation and early management of patients with severe injuries during the last decade. These have come about as a result of the reorganisation of civilian trauma services in countries such as Germany, Australia and the United States, where the development of trauma systems has allowed a concentration of expertise and research. The continuing conflicts in the Middle East have also generated a significant increase in expertise in the management of severe injuries, and soldiers now survive injuries that would have been fatal in previous wars. This military experience is being translated into civilian practice. The aim of this paper is to give orthopaedic surgeons a practical, evidence-based guide to the current management of patients with severe, multiple injuries. It must be emphasised that this depends upon the expertise, experience and facilities available within the local health-care system, and that the proposed guidelines will inevitably have to be adapted to suit the local resources.

Full Text Available Abstract Background Variations in corticosteroid/anesthetic doses for injecting shoulder conditions were examined among orthopaedic surgeons, rheumatologists, and primary-care sports medicine (PCSMs and physical medicine and rehabilitation (PMRs physicians to provide data needed for documenting inter-group differences for establishing uniform injection guidelines. Methods 264 surveys, sent to these physicians in our tri-state area of the western United States, addressed corticosteroid/anesthetic doses and types used for subacromial impingement, degenerative glenohumeral and acromioclavicular arthritis, biceps tendinitis, and peri-scapular trigger points. They were asked about preferences regarding: 1 fluorinated vs. non-fluorinated corticosteroids, 2 acetate vs. phosphate types, 3 patient age, and 4 adjustments for special considerations including young athletes and diabetics. Results 169 (64% response rate, RR surveys were returned: 105/163 orthopaedic surgeons (64%RR, 44/77 PCSMs/PMRs (57%RR, 20/24 rheumatologists (83%RR. Although corticosteroid doses do not differ significantly between specialties (p > 0.3, anesthetic volumes show broad variations, with surgeons using larger volumes. Although 29% of PCSMs/PMRs, 44% rheumatologists, and 41% surgeons exceed "recommended" doses for the acromioclavicular joint, >98% were within recommendations for the subacromial bursa and glenohumeral joint. Depo-Medrol® (methylprednisolone acetate and Kenalog® (triamcinolone acetonide are most commonly used. More rheumatologists (80% were aware that there are acetate and phosphate types of corticosteroids as compared to PCSMs/PMRs (76% and orthopaedists (60%. However, relatively fewer rheumatologists (25% than PCSMs/PMRs (32% or orthopaedists (32% knew that phosphate types are more soluble. Fluorinated corticosteroids, which can be deleterious to soft tissues, were used with these frequencies for the biceps sheath: 17% rheumatologists, 8% PCSMs/PMRs, 37

Full Text Available BACKGROUND: In February 2007, a general surgeon in Charlottetown, Prince Edward Island, tested positive for hepatitis C virus (HCV. The surgeon’s infection onset date could not be determined; however, episodic hepatic enzyme elevations were first detected in November 2004 and again in February 2007. HCV transmission during surgery, alhough rare, has been documented. A phased look-back HCV screening program was conducted to detect HCV transmission from this surgeon to patients who underwent the highest-risk procedures in the three years before his positive test.
Do geography and resources influence the need for colostomy in Hirschsprung′s disease and anorectal malformations? A Canadian association of paediatric surgeons: Association of paediatric surgeons of Nigeria survey
Lukman O. Abdur-Rahman
Full Text Available Background: This survey compared surgical management of Hirschsprung′s disease (HD and anorectal malformations (ARM in high and low resource settings. Materials and Methods: An online survey was sent to 208 members of the Canadian Association of Paediatric Surgeons (CAPS and the Association of Paediatric Surgeons of Nigeria (APSON. Results: The response rate was 76.8% with 127 complete surveys (APSON 34, CAPS 97. Only 29.5% of APSON surgeons had frozen section available for diagnosis of HD. They were more likely to choose full thickness rectal biopsy (APSON 70.6% vs. CAPS 9.4%, P < 0.05 and do an initial colostomy for HD (APSON 23.5% vs. CAPS 0%, P < 0.05. Experience with trans-anal pull-through for HD was similar in both groups (APSON 76.5%, CAPS 66.7%. CAPS members practising in the United States were more likely to perform a one-stage pull-through for HD during the initial hospitalization (USA 65.4% vs. Canada 28.3%, P < 0.05. The frequency of colostomy in females with vestibular fistula varied widely independent of geography. APSON surgeons were less likely to have enterostomal therapists and patient education resources. Conclusions: Local resources which vary by geographic location affect the management of HD and ARM including colostomy. Collaboration between CAPS and APSON members could address resource and educational needs to improve patient care.

It is becoming widely accepted that research which considers only the outcome and not the costs associated with new technologies in health care, is of limited value in making decisions about the use of scarce resources. Economic evaluation is becoming a standard feature of clinical research but many published economic evaluations fall short of best practice in their methodology. We have described the essential features of economic evaluation, using published studies in orthopaedics, in order to try to improve the ability of orthopaedic surgeons to read, understand and appraise such studies critically, and to encourage them to consider including economic evaluation in future investigations.

Stereoscopy was used in medicine as long ago as 1898, but has not gained widespread acceptance except for a peak in the 1930's. It retains a use in orthopaedics in the form of Radiostereogrammetrical Analysis (RSA), though this is now done by computer software without using stereopsis. Combining computer assisted stereoscopic displays with both conventional plain films and reconstructed volumetric axial data, we are reassessing the use of stereoscopy in orthopaedics. Applications include use in developing nations or rural settings, erect patients where axial imaging cannot be used, and complex deformity and trauma reconstruction. Extension into orthopaedic endoscopic systems and teaching aids (e.g. operative videos) are further possibilities. The benefits of stereoscopic vision in increased perceived resolution and depth perception can help orthopaedic surgeons achieve more accurate diagnosis and better pre-operative planning. Limitations to currently available stereoscopic displays which need to be addressed prior to widespread acceptance are: availability of hardware and software, loss of resolution, use of glasses, and image "ghosting". Journal publication, the traditional mode of information dissemination in orthopaedics, is also viewed as a hindrance to the acceptance of stereoscopy - it does not deliver the full impact of stereoscopy and "hands-on" demonstrations are needed.

Since 2005, Barwon Health has successfully reformed its orthopaedic outpatient service to address the following issues: increasing number of referrals, inefficient referral management and triage, long waiting times for non-urgent appointments, high 'Did Not Attend' (DNA) rates and poor utilisation of conservative therapies before referral to surgeon. Numerous strategies have been implemented including: waiting list audits, triage guidelines, physiotherapy-led clinics, a DNA policy, an orthopaedic lead nurse role and a patient-focussed booking system. There has been a 66% reduction in the number of patients waiting for their first appointment; an 87% reduction in the waiting time from referral to first appointment; a 10% reduction in new patient DNAs; and more efficient referral management and communication processes. Patients are now seen in clinically appropriate time frames and offered earlier access to a wider range of conservative treatments. PMID:22624648

Spasticity is a common manifestation of many neurological conditions including multiple sclerosis, stroke, cerebral palsy, traumatic brain injury, and spinal cord injuries. Management of spasticity seeks to reduce its burden on patients and to limit secondary complications. Non-operative interventions including stretching/splinting, postural management, physical therapy/strengthening, anti-spasticity medications, and botulinum toxin injections may help patients with spasticity. Surgical management of these conditions, however, is often necessary to improve quality of life and prevent complications. Orthopaedic surgeons manage numerous sequelae of spasticity, including joint contractures, hip dislocations, scoliosis, and deformed extremities. When combined with the efforts of rehabilitation specialists, neurologists, and physical/occupational therapists, the orthopaedic management of spasticity can help patients maintain and regain function and independence as well as reduce the risk of long-tem complications.

Members of orthopaedic industry commit a significant amount of funds each year to support research and education programs that are directly related to their product(s). In addition, industry supports organizations such as the Orthopaedic Research and Education Foundation. The relationship between the Orthopaedic Research and Education Foundation and industry began in the early 1980s. The support to the Orthopaedic Research and Education Foundation from industry primarily has come in the form of unrestricted grants. These grants best can be looked at as an investment rather than a contribution. This form of giving, once called corporate philanthropy is more accurately referred to as strategic philanthropy. Members of industry make these investments to enhance their reputations, build brand awareness, market their products and services, improve employee morale, increase customer loyalty, and establish strategic alliances. The specialty of orthopaedics is among the leaders in medicine in the amount of funding raised within the specialty for research and education programs. This is because of the amount of support from members of industry and the surgeons. During the past 15 years, 40% of the annual support to the Orthopaedic Research and Education Foundation has come from industry and the balance has come from surgeons and members of lay public. Future industry support of the Orthopaedic Research and Education Foundation and other organizations within the specialty of orthopaedics will be dependent on the continued demonstration of tangible returns in areas described.

Leadership and business challenges have become increasingly present in the practice of medicine. Orthopaedic residency programs are at the forefront of educating and preparing orthopaedic surgeons. This study attempts to quantify the number of orthopaedic residency programs in the United States that include leadership or business topics in resident education program and to determine which topics are being taught and rate the importance of various leadership characteristics and business topics. A survey was sent to all orthopaedic department chairpersons and residency program directors in the United States via e-mail. The survey responses were collected using a survey collection website. The respondents rated the importance of leadership training for residents as somewhat important. The quality of character, integrity, and honesty received the highest average rating among 19 different qualities of good leaders in orthopaedics. The inclusion of business training in resident education was also rated as somewhat important. The topic of billing and coding received the highest average rating among 14 different orthopaedically relevant business topics. A variety of topics beyond the scope of clinical practice must be included in orthopaedic residency educational curricula. The decreased participation of newly trained orthopaedic surgeons in leadership positions and national and state orthopaedic organizations is concerning for the future of orthopaedic surgery. Increased inclusion of leadership and business training in resident education is important to better prepare trainees for the future. PMID:21838073

Understanding the relevant legal context is critical to the safe and successful practice of orthopaedic surgery. Specifically, three areas of liability are relevant to most physicians: medical malpractice, products liability, and the liability of health care organizations. Medical malpractice encompasses the professional physician-patient relationship with its implied contract, consent, fiduciary responsibilities, and duty to provide the standard of care, as well as certain common-law duties pertinent in special circumstances. Orthopaedic surgeons who design implants or who have a relationship with a device manufacturer are at risk for liability for a failed product. In general, the hospital entity is responsible for the actions of its physician-employees. Still unclear is the degree to which a physician is obligated to appeal to a third-party payer on behalf of a patient. Physicians should remember that, above all else, common sense with regard to the treatment, informed consent, and advocacy of patients is essential to avoiding many medical-legal pitfalls.

Objective: To assess the capability of operating abdominal and orthopaedic surgeons to analyze a set of standardized ECG. Methods: Twenty operating abdominal and orthopaedic surgeons at a university hospital were included. Each participant analyzed a set of five standardized ECG with an answering scheme for eight different items, giving a maximum score of 40. The answers were matched according to specialty and experience of the doctors of less than 5 years, between 5 and 10 years or more than 10 years. The reference standard was set by two independent consultants in cardiology. Results: The mean overall score was 25.25 (63.13%±4.78%) varying between 38 (95%) and 20(50%). Abdominal surgeons performed a mean score of 27.625 (69.06%±9.53%), and orthopaedic surgeons 23.67 points (59.17%±3.69%). The difference between the performance of abdominal and orthopaedic surgeons was not significant (P=0.09). 20/20 surgeons identified ST-elevation and no surgeon accepted the ECG showing acute ST-elevation myocardial infarction as normal. Conclusions: Abdominal and orthopaedic surgeons provided an answering scheme are able to interprete the ECG and identify both the normal and the ECG showing life-threatening pathology. The hypothesis that surgeons were unable to interprete the ECG must be rejected.

Stress, emotional exhaustion, and burnout are widespread in the medical profession in general and in orthopaedic surgery in particular. We attempted to identify variables associated with burnout as assessed by validated instruments. Surveys were sent to 282 leaders from orthopaedic surgery academic departments in the United States by e-mail and mail. Responses were received from 195 leaders for a response rate of 69%. The average surgeon worked 68.3 hours per week and more than ½ of this time...
The paradigm of coping with sometimes gross pathology, while having some small and at first sight insignificant lesions demands for accurate radiological detection and orthopaedic treatment makes it interesting and challenging to be involved in the treatment of professional athletes. In the diagnostic process we differentiate between acute, posttraumatic and overuse injuries. We must realize the importance of reproducible routine X-rays as a first step in the diagnostic process. In case of additional diagnostics, appropriate consultation between the orthopaedic surgeon and the radiologist is essential in order to determine the best strategy

The lack of clinical residents especially in the surgical domains, including orthopaedics and trauma surgery, is not only omnipresent but also a topic of lively discussions. This lack originates from sociopolitical and healthcare policy issues as well as from a loss of attractiveness of all surgical disciplines. The loss is caused by the high workload and disadvantageous working hours especially in those disciplines with a high rate of emergencies, e.g. trauma surgery. Moreover, it is caused by the poorly structured and unpredictable period of residency. In order to anticipate the bottleneck in supply due to the lack of trainees, a number of structural and contextual measures have to be taken to improve both undergraduate und postgraduate surgical training. Due to the numerous facets of the topic the first part of this analysis refers to the period until the trainee decides on the field of training.A basic insight into the field of orthopaedics and trauma surgery can already be offered far before the period of medical studies itself. During undergraduate medical education the existing structures should be modified, the characteristics of the discipline should be emphasized and the charm of combining theory and practical skills should be highlighted in order to enhance student's perception of the discipline. This might begin during preclinical training and should be continued throughout clinical training and elective courses (basic wound care, TEAM approach, AO course for students and seminars for M.D. candidates). Contextual and structural improvements of the practical year are indispensable to arouse students' interest in our discipline. These options conjoined with the actual offers for students provided by our scientific society, such as guided tours during the annual congress, travelling grants and the recently inaugurated summer school, might provide the basis for clearly structured information and offer a distinct stimulus to apply for residency in our field

Paralytic ileus is marked by the cessation of bowel motility. This condition is a major clinical concern that may lead to severe patient morbidity in orthopaedic surgery and trauma patients. Ileus most commonly occurs following spinal surgery, traumatic injury, or lower extremity joint reconstruction, but it may also occur following minor orthopaedic procedures. Possible consequences of ileus include abdominal pain, malnutrition, prolonged hospital stay, hospital readmission, bowel perforation, and death. Therapies used in the treatment of ileus include minimization of opioids, early patient mobilization, pharmacologic intervention, and multidisciplinary care. Orthopaedic surgeons should be aware of the clinical signs and symptoms of paralytic ileus and should understand treatment principles of this relatively common adverse event. PMID:25917235

For 30 years, the orthopaedic faculty at Case Western Reserve University worked as an independent private corporation within University Hospitals Case Medical Center (Hospital). However, by 2002, it became progressively obvious to our orthopaedic practice that we needed to modify our business model to better manage the healthcare regulatory changes and decreased reimbursement if we were to continue to attract and retain the best and brightest orthopaedic surgeons to our practice. In 2002, our...

Over the past half-century, biomaterials have been used in orthopaedic surgery world widely, but orthopaedic implant-associated infections (OIAIs) are still a puzzle for orthopaedic surgeons, which may result in prolonged hospitalisation, poor functional status and high costs. The presence of implants increases the risk of microbial infection; moreover, the formation of bacterial biofilm leads to a higher resistance to antibiotics and local immune response. In such cases, conventional systemi...

Full Text Available Introduction. The Royal College of Surgeons in England published guidelines in 2008 outlining the information that should be documented at each surgery. St. James’s Hospital uses a standard operation sheet for all surgical procedures and these were examined to assess documentation standards. Objectives. To retrospectively audit the hand written orthopaedic operative notes according to established guidelines. Methods. A total of 63 operation notes over seven months were audited in terms of date and time of surgery, surgeon, procedure, elective or emergency indication, operative diagnosis, incision details, signature, closure details, tourniquet time, postop instructions, complications, prosthesis, and serial numbers. Results. A consultant performed 71.4% of procedures; however, 85.7% of the operative notes were written by the registrar. The date and time of surgery, name of surgeon, procedure name, and signature were documented in all cases. The operative diagnosis and postoperative instructions were frequently not documented in the designated location. Incision details were included in 81.7% and prosthesis details in only 30% while the tourniquet time was not documented in any. Conclusion. Completion and documentation of operative procedures were excellent in some areas; improvement is needed in documenting tourniquet time, prosthesis and incision details, and the location of operative diagnosis and postoperative instructions.

Operative surgery exposes the surgeon to possible blood-borne infections. Risks include pen-etrating injuries and conjunctival contact with infected blood. Visor masks worn during orthopaedic trauma procedures were assessed for blood contamination using computer analysis. This was found to be present on 86% of masks, of which only 15% was recognized by the surgeon intraoperatively. Of the blood splashes 80% were less than 0.6mm in diameter. We conclude that power instrumentation produces a blood particulate mist causing considerable microscopic, facial contamination which is a significant risk to the surgeon.

Objectives Despite the fact that research fraud and misconduct are under scrutiny in the field of orthopaedic research, little systematic work has been done to uncover and characterise the underlying reasons for academic retractions in this field. The purpose of this study was to determine the rate of retractions and identify the reasons for retracted publications in the orthopaedic literature. Methods Two reviewers independently searched MEDLINE, EMBASE, and the Cochrane Library (1995 to current) using MeSH keyword headings and the ‘retracted’ filter. We also searched an independent website that reports and archives retracted scientific publications (www.retractionwatch.com). Two reviewers independently extracted data including reason for retraction, study type, journal impact factor, and country of origin. Results One hundred and ten retracted studies were included for data extraction. The retracted studies were published in journals with impact factors ranging from 0.000 (discontinued journals) to 13.262. In the 20-year search window, only 25 papers were retracted in the first ten years, with the remaining 85 papers retracted in the most recent decade. The most common reasons for retraction were fraudulent data (29), plagiarism (25) and duplicate publication (20). Retracted articles have been cited up to 165 times (median 6; interquartile range 2 to 19). Conclusion The rate of retractions in the orthopaedic literature is increasing, with the majority of retractions attributed to academic misconduct and fraud. Orthopaedic retractions originate from numerous journals and countries, indicating that misconduct issues are widespread. The results of this study highlight the need to address academic integrity when training the next generation of orthopaedic investigators. Cite this article: J. Yan, A. MacDonald, L-P. Baisi, N.

Full Text Available International evidence-based guidelines for the management of patients with hip and knee osteoarthritis (OA recommend to start with (a combination of non-surgical treatments, and using surgical intervention only if a patient does not respond sufficiently to non-surgical treatment options. Despite these recommendations, there are strong indications that non-surgical treatments are not optimally used in orthopaedic practice. To improve the adoption of non-surgical treatments, more insight is needed into barriers and facilitators of these treatments. Therefore, this study assessed which barriers and facilitators are associated with the use and prescription of different non-surgical treatments before hip and knee OA in orthopaedic practice among patients and orthopaedic surgeons in the Netherlands.We performed two internet-based surveys among 172 orthopaedic surgeons and 174 OA patients. Univariate association and multivariable regression techniques are used to identify barriers and facilitators associated with the use of non-surgical treatments.Most barriers and facilitators among patients were associated with the use of physical therapy, lifestyle advice and dietary therapy. Among orthopaedic surgeons, most were associated with prescription of acetaminophen, dietary therapy and physical therapy. Examples of barriers and facilitators among patients included "People in my environment had positive experiences with a surgery" (facilitator for education about OA, and "Advice of people in my environment to keep on moving" (facilitator for lifestyle and dietary advice. For orthopaedic surgeons, examples were "Lack of knowledge about guideline" (barrier for lifestyle advice, "Agreements/ deliberations with primary care" and "Easy communication with a dietician" (facilitators for dietary therapy. Also the belief in the efficacy of these treatments was associated with increased prescription.Strategies to improve non-surgical treatment use in orthopaedic
Background Globally, injuries cause approximately as many deaths per year as HIV/AIDS, tuberculosis and malaria combined, and 90% of injury deaths occur in low- and middle- income countries. Given not all injuries kill, the disability burden, particularly from orthopaedic injuries, is much higher but is poorly measured at present. The orthopaedic services and orthopaedic medical devices needed to manage the injury burden are frequently unavailable in these countries. Corruption is known to be a major barrier to access of health care, but its effects on access to orthopaedic services is still unknown. Methods A qualitative case study of 45 open-ended interviews was conducted to investigate the access to orthopaedic health services and orthopaedic medical devices in Uganda. Participants included orthopaedic surgeons, related healthcare professionals, industry and government representatives, and patients. Participants’ experiences in accessing orthopaedic medical devices were explored. Thematic analysis was used to analyze and code the transcripts. Results Analysis of the interview data identified poor leadership in government and corruption as major barriers to access of orthopaedic care and orthopaedic medical devices. Corruption was perceived to occur at the worker, hospital and government levels in the forms of misappropriation of funds, theft of equipment, resale of drugs and medical devices, fraud and absenteeism. Other barriers elicited included insufficient health infrastructure and human resources, and high costs of orthopaedic equipment and poverty. Conclusions This study identified perceived corruption as a significant barrier to access of orthopaedic care and orthopaedic medical devices in Uganda. As the burden of injury continues to grow, the need to combat corruption and ensure access to orthopaedic services is imperative. Anti-corruption strategies such as transparency and accountability measures, codes of conduct, whistleblower protection, and higher

Over years of practice, many beliefs and practices become entrenched as tried and tested, and we subconsciously believe they are based on scientific evidence. We identified nine such beliefs by interviewing orthopaedic surgeons in which studies (or lack thereof) apparently do not support such practices. These are: changing the scalpel blade after the skin incision to limit contamination; bending the patient’s knee when applying a thigh tourniquet; bed rest for treatment of deep vein thrombosi...

Thromboembolic events are a post-operative complication of arthroplasty surgery for up to 3 months. The incidence however, is not fully known. Some form of prophylaxis should be provided to all arthroplasty patients. Clinicians are wary of side effects, compliance profile and the associated cost. The objective of this study is to investigate practice patterns and their relevance to 3 risk groups. Ninety questionnaires were sent to orthopaedic surgeons with 3 hypothetical clinical scenarios and 10 prophylaxis regimes for thromboembolism across different risk groups. The response rate was 81\\/90 (90%). The most popular options in all 3 cases were early mobilisation, thrombo-embolism deterrant (TED) stockings and low molecular weight heparin (LMWH) (51\\/81, 62% of all cases). An inconsistent relationship exists between preferred practice and relevant guidelines. Preferred practice does not correlate with each level of risk.

➤Advances in combined antiretroviral therapy (cART) in recent years have transformed HIV infection into a chronic disease when treatment is available, increasing a patient's life expectancy and the chances that orthopaedic surgeons will encounter such patients in their clinical practice.➤Musculoskeletal manifestations in patients with HIV infection are common and sometimes are the initial presentation of the disease. Knowledge about neoplasms and associated conditions affecting muscle, bones, and joints is essential for successful management.➤Since the advent of cART, total joint arthroplasty has been shown to be a safe procedure; however, perioperative infection is still a small risk in patients with uncontrolled viral loads or CD4 counts of nutritional status, cART therapy, viral load count, and other comorbidities (hemophilia, infection among intravenous drug users, etc.) should be considered when treating these patients in order to optimize their clinical outcomes.

This article establishes the biography of a little known physician of the 19th century., whose commitment with orthopaedics and formulation of medical gymnastics was important: the surgeon-orthopaedist Sauveur-Henri-Victor Bouvier. Several constitutive processes of the medical field of the 19th century are analysed: specialization (around orthopaedics), professionalization and development of various therapeutic and hygienic methods (among them medical gymnastics). Bouvier's biography is particularly instructive and sheds new light on these different processes, as well as on the institutionalization of orthopaedics from the 1820's up to the 1870's, at the intersection between medical and educative fields, between hospital, medical faculty and teaching of gymnastics.

Every year, hundreds of new surgeons graduate from residency programs across Canada. Much time and effort is spent on preparing these surgeons for independent practice, but there is little literature about the career trajectories of surgeons after they finish training and enter practice. We surveyed all surgeons graduating from the residency programs of a single Canadian medical school over 25 years (1985–2010). Most respondents rated their job satisfaction as high/very high and indicated the...

Military surgeons are a special group of doctors. They are both medical workers and soldiers.Their mission is to serve the wounded on the battlefield.And there is no doubt that military surgeons will save our comrades in the army. However,should a military surgeon save the wounded enemy? It is indeed a dilemma.Some may save the wounded enemy because military surgeons are doctors after all and they can't possibly abandon anybody to his fate,but some refuse to do so because military surgeons are soldiers.Therefore,some situations on the battlefield are discussed and advice is suggested for military surgeons,with heartfelt anticipation for there being less casualties on the battlefield as well as alleviating human suffering caused by war.
In orthopaedic and trauma surgery, the rapid evolution of biomedical research has fundamentally changed the perception of the musculoskeletal system. Here, the rigor of basic science and the art of musculoskeletal surgery have come together to create a new discipline -experimental orthopaedics- that holds great promise for the causative cure of many orthopaedic conditions. The Journal of Experimental Orthopaedics intends to bridge the gap between orthopaedic basic science and clinical relevan...

Over years of practice, many beliefs and practices become entrenched as tried and tested, and we subconsciously believe they are based on scientific evidence. We identified nine such beliefs by interviewing orthopaedic surgeons in which studies (or lack thereof) apparently do not support such practices. These are: changing the scalpel blade after the skin incision to limit contamination; bending the patient's knee when applying a thigh tourniquet; bed rest for treatment of deep vein thrombosis; antibiotics in irrigation solution; routine use of hip precautions; routine use of antibiotics for the duration of wound drains; routine removal of hardware in children; correlation between operative time and infection; and not changing dressings on the floor before scrubbing. A survey of 186 practicing orthopaedic surgeons in academic and community settings was performed to assess their routine practice patterns. We present the results of the survey along with an in-depth literature review of these topics. Most surgeon practices are based on a combination of knowledge gained during training, reading the literature, and personal experience. The results of this survey hopefully will raise the awareness of the selected literature for common practices. PMID:18726654
Abstract Background Despite having access to medically necessary care available through publicly funded provincial health care systems, some Canadians travel for treatment provided at international medical facilities as well as for-profit clinics found in several Canadian provinces. Canadians travel abroad for orthopaedic surgery, bariatric surgery, ophthalmologic surgery, stem cell injections, “Liberation therapy” for multiple sclerosis, and additional interventions. Both responding to publi...

Currently, general surgeons provide about 50% of endoscopy services across Canada and an even greater proportion outside large urban centres. It is essential that endoscopy remain a core component of general surgery practice and a core competency of general surgery residency training. The Canadian Association of General Surgeons Residents Committee supports the position that quality endoscopy training for all Canadian general surgery residents is in the best interest of the Canadian public.

The burden of musculoskeletal conditions, especially injuries, is increasing in low-income and middle-income countries. Road traffic injuries have become epidemic. There are multiple barriers to accessing surgical services at both the individual (utilization) and the health system (availability) levels, and deficiencies in education and training of health providers. Specialty societies such as the Pediatric Orthopaedic Society of North America (POSNA) have an opportunity to play an important role through teaching and training. The POSNA Children's Orthopedics in Underserved Regions (COUR) committee has supported the Visiting Scholars Program, which invites surgeons from the developing world to attend a scientific meeting and facilitates the scholar's visit to North American pediatric orthopaedic centers. POSNA members have held global educational courses that support an educational exchange between lecturers and attendees. The COUR web site allows for submission of trip reports that document successes and obstacles experienced by members performing overseas clinical care and teaching. The web site also provides educational resources relevant to providing care in these environments. POSNA collaborates with other societies, such as the American Academy of Orthopaedic Surgeons and the Society of Military Orthopaedic Surgeons, to provide education in disaster management. In addition to increasing member involvement, specialty societies have the opportunity for continued data collection from overseas care, application of US registry data to disease processes in the developing world, and further collaboration with one another.

Full Text Available Road traffic accidents are increasing at an alarming rate and have become a major public health concern in India. In addition, there is a lack of trauma research output and reliable data from India. There are several issues and challenges that have presented an opportunity for researchers and surgeons in India to develop a collaborative aimed at improving the quality and productivity of orthopaedic trauma research. Establishing a network of surgical researchers across India is a necessary first step towards global leadership in orthopaedic surgery trials.

INTRODUCTION Clinical audit plays an important role in the drive to improve the quality of patient care and thus forms a cornerstone of clinical governance. Assurance that the quality of patient care has improved requires completion of the audit cycle. A considerable sum of money and time has been spent establishing audit activity in the UK. Failure to close the loop undermines the effectiveness of the audit process and wastes resources. PATIENTS AND METHODS We analysed the effectiveness of audit in trauma and orthopaedics at a local hospital by comparing audit projects completed over a 6-year period to criteria set out in the NHS National Audit and Governance report. RESULTS Of the 25 audits performed since 1999, half were presented to the relevant parties and only 20% completed the audit cycle. Only two of these were audits against national standards and 28% were not based on any standards at all. Only a third of the audits led by junior doctors resulted in implementation of their action plan compared to 75% implementation for consultant-led and 67% for nurse-led audits. CONCLUSIONS A remarkably large proportion of audits included in this analysis failed to meet accepted criteria for effective audit. Audits completed by junior doctors were found to be the least likely to complete the cycle. This may relate to the lack of continuity in modern medical training and little incentive to complete the cycle. Supervision by permanent medical staff, principally consultants, and involvement of the audit department may play the biggest role in improving implementation of change. PMID:18828963

Changing patterns of health care delivery and the rapid evolution of orthopaedic surgical techniques have made it increasingly difficult for trainees to develop expertise in their craft. Working hour restrictions and a drive towards senior led care demands that proficiency be gained in a shorter period of time whilst requiring a greater skill set than that in the past. The resulting conflict between service provision and training has necessitated the development of alternative methods in order to compensate for the reduction in 'hands-on' experience. Simulation training provides the opportunity to develop surgical skills in a controlled environment whilst minimising risks to patient safety, operating theatre usage and financial expenditure. Many options for simulation exist within orthopaedics from cadaveric or prosthetic models, to arthroscopic simulators, to advanced virtual reality and three-dimensional software tools. There are limitations to this form of training, but it has significant potential for trainees to achieve competence in procedures prior to real-life practice. The evidence for its direct transferability to operating theatre performance is limited but there are clear benefits such as increasing trainee confidence and familiarity with equipment. With progressively improving methods of simulation available, it is likely to become more important in the ongoing and future training and assessment of orthopaedic surgeons. PMID:25523023

Thioureas, often contained within neoprene to provide water resistance, are an important cause of allergic contact dermatitis (ACD) in those who use neoprene products. We wish to present three cases of thiourea-induced ACD from three different orthopaedic supports containing neoprene. The first case was a 67-year-old woman who developed an itchy rash on her heel three weeks after using a neoprene insole for plantar fasciitis. The second case was a 47-year-old man who developed an itchy rash on his wrist after wearing neoprene wrist splints for psoriatic arthropathy. The third case was a 77-year-old woman who experienced a severe erythematous rash with blistering from a neoprene elbow brace she received following a humeral fracture. All patients were patch tested to the British Society of Cutaneous Allergy Standard and rubber series and a cut piece from all the relevant supports. At 96 hours, all patients had a + reaction to mixed dialkylthiourea, diethylthiourea, and the supports' material. No other positive patch test reactions were identified. As neoprene is fast becoming one of the most popular materials used for orthopaedic supports, awareness of this reaction and close liaison between dermatologists and orthopaedic surgeons are therefore essential to allow for early recognition of this complication.

Background: Despite the common nature of orthopaedic injuries in equestrian sports, there is no published review to specifically characterize orthopaedic injuries in equestrian athletes. Purpose: To characterize orthopaedic injury patterns in equine sports–related injuries and their treatment. Study Design: Systematic review; Level of evidence, 4. Methods: This review was performed through a PubMed, EMBASE, and Scopus query (from 1978 to June 2014) in the English literature using search terms “(equine-related OR equestrian-related OR horse-related OR equestrian OR equestrians) AND (injury OR injuries).” Only full-text studies reporting on orthopaedic injury patterns pertinent to equestrian sports in the United States (US) and the United Kingdom (UK) were included. Orthopaedic injuries were defined as those resulting in a fracture or dislocation. In all, 182 studies were excluded, leaving a total of 27 studies for evaluation. The studies included were analyzed for demographic and epidemiological data for orthopaedic injuries, including fractures and dislocations. Cranial and facial injuries were excluded from analysis. Results: The majority of those injured in the US were female (64.5%). The leading cause of injury in the US was falling from a horse. The use of protective equipment seemed to vary widely, with helmet use ranging from less than 6% up to 66.7%. In the UK, fractures were found to account for 17.4% of reported injures, compared with 33.6% of injuries in the US. The majority of fractures in US riders occurred in the upper extremities (50.7%). Conclusion: This review helps characterize the epidemiology of equestrian injuries based on currently available data. PMID:26535400

General Surgery is a broad surgical specialty that focuses on diseases related to abdominal organs, skins and hernias, both in elective and emergency settings. With the prevalent trend for increasing subspecialisation in today's surgical practice, general surgery has lost some of its former glory and scope. This has led to suffering of the image of the general surgeons (GS) in the eyes of trainees, peers, the public and even GS themselves. A comprehensive review of literature is presented to address the controversy surrounding the role and future of general and specialist surgeons in the current perspectives. PMID:20795470
Surgeons and clinical staff, theatre circulation and scrub personnel, and anaesthetists, as well as the estates and facilities team at Kent's Maidstone Hospital, have worked with specialist supplier of integrated audio, video, and instrumentation systems for the operating room, Olympus Medical, to develop what is claimed is among the UK's most advanced operating theatres yet built for laparoscopic and endoscopic surgery. HEJ editor Jonathan Baillie discussed the project with Amir Nisar, the surgeon who championed efforts to get the facility built, and Olympus Medical national sales manager, systems integration, James Watts.

The First World War (1914-1918) was the first truly industrial conflict in human history. Never before had rifle fire and artillery barrage been employed on a global scale. It was a conflict that over 4 years would leave over 750,000 British troops dead with a further 1.6 million injured, the majority with orthopaedic injuries. Against this backdrop, the skills of the orthopaedic surgeon were brought to the fore. Many of those techniques and systems form the foundation of modern orthopaedic trauma management. On the centenary of 'the War to end all Wars', we review the significant advances in wound management, fracture treatment, nerve injury and rehabilitation that were developed during that conflict.

Nanotechnology is the application of science and engineering at the nanoscale. A diverse range of applications are beginning to emerge in all areas of medicine. We performed a survey from November 2005 to March 2006 using the Internet search engines PubMed, ScienceDirect, ISI Web of Knowledge, and Google Scholar. We report on the role of nanotechnology in orthopaedics, exploring current and potential applications. Nanostructured materials have been proposed as the next generation of orthopaedic implant properties by creating a surface environment more conducive for osteoblast function. Bone substitute materials, whose nanoscale composition emulates the hierarchic organization of natural bone, shows initiation of the desirable formation of an apatite layer. Nanotechnology also has been harnessed to improve the cutting performance and quality of surgical blades. Postoperative infection rates may be reduced by using nanofibrous membrane wound dressings containing antibacterial properties. The most notable application of nanotechnology in orthopaedics may be drug delivery, including nanotherapeutics for treating bone cancer and arthritis. Nanotechnology is being used in orthopaedics, and likely will play a valuable role in future developments. PMID:17224843

Full Text Available Abstract Background Various procedures, especially minimal invasive techniques using fluoroscopy, pose a risk of radiation exposure to orthopaedic staff. Anatomical sites such as the eyes, thyroid glands and hands are more vulnerable to radiation considering the limited use of personal protective devices in the workplace. The objective of the study is to assess the annual mean cumulative and per procedure radiation dose received at anatomical locations like eyes, thyroid glands and hands in orthopaedic staff using systematic review. Methods The review of literature was conducted using systematic search of the database sources like PUBMED and EMBASE using appropriate keywords. The eligibility criteria and the data extraction of literature were based on study design (cohort or cross-sectional study, study population (orthopaedic surgeons or their assistants, exposure (doses of workplace radiation exposure at hands/fingers, eye/forehead, neck/thyroid, language (German and English. The literature search was conducted using a PRISMA checklist and flow chart. Results Forty-two articles were found eligible and included for the review. The results show that radiation doses for the anatomical locations of eye, thyroid gland and hands were lower than the dose levels recommended. But there is a considerable variation of radiation dose received at all three anatomical locations mainly due to different situations including procedures (open and minimally invasive, work experience (junior and senior surgeons,distance from the primary and secondary radiation, and use of personal protective equipments (PPEs. The surgeons receive higher radiation dose during minimally invasive procedures compared to open procedures. Junior surgeons are at higher risk of radiation exposure compared to seniors. PPEs play a significant role in reduction of radiation dose. Conclusions Although the current radiation precautions appear to be adequate based on the low dose radiation

The Accreditation Council of Graduate Medical Education requires that residency programs teach and assess trainees in six core competencies. Assessments are imperative to determine trainee competence and to ensure that excellent care is provided to all patients. A structured, direct observation program is feasible for assessing nontechnical core competencies and providing trainees with immediate constructive feedback. Direct observation of residents in the outpatient setting by trained faculty allows assessment of each core competency. Checklists are used to document residents' basic communication skills, clinical reasoning, physical examination methods, and medical record keeping. Faculty concerns regarding residents' professionalism, medical knowledge, fatigue, or ability to self-assess are tracked. Serial observations allow for the reinforcement and/or monitoring of skills and attitudes identified as needing improvement. Residents who require additional coaching are identified early in training. Progress in educational milestones is recorded, allowing an individualized educational program that ensures that future orthopaedic surgeons excel across all domains of medical and surgical competence.

Full Text Available In October 2013, the International Combined Orthopaedic Research Societies (ICORS; http://i-cors.org was founded with inaugural member organisations from the previous Combined Orthopaedic Research Society, which had sponsored combined meetings for more than 2 decades. The ICORS is dedicated to the stimulation of orthopaedic and musculoskeletal research in fields such as biomedical engineering, biology, chemistry, and veterinary and human clinical research. The ICORS seeks to facilitate communication with member organisations to enhance international research collaborations and to promote the development of new international orthopaedic and musculoskeletal research organisations. Through new categories of membership, the ICORS represents the broadest coalition of orthopaedic research organisations globally.
OBJECTIVE: To report on the perceptions of a group of orthopaedic trainees and trainers on perceived effects of the proposed introduction of European Working Time Directive (EWTD) restrictions into Ireland and on the use of simulators in training orthopaedic skills. METHODS: A structured questionnaire was developed to evaluate the opinions of a group of orthopaedic surgeons and trainees at the annual national orthopaedic conference. RESULTS: There were 44 participants [12 consultants, 32 trainees (15 specialist registrars, 8 registrars, 9 senior house officers)]. Seventy-five percent of participants felt that both the quality of patient care and training would be negatively affected. A higher proportion of consultants than trainees felt that quality of life would be affected. A high proportion of participants (81.8%) had used a simulator or model to learn a surgical skill and 100% would consider using them again. CONCLUSIONS: While we wait for the full introduction of the EWTD hours the perception is that both quality of patient care and training will be affected. Models and simulators are well perceived as a method of training.

Objectives To investigate whether a surgeon can drill accurately a specified angle and whether surgeon experience, task repetition, drill bit size and perceived difficulty influence drilling angle accuracy. Methods The sample population consisted of final-year students (n=25), non-specialist veterinarians (n=22) and board-certified orthopaedic surgeons (n=8). Each participant drilled a hole twice in a horizontal oak plank at 30°, 45°, 60°, 80°, 85° and 90° angles with either a 2.5 or a 3.5 mm drill bit. Participants then rated the perceived difficulty to drill each angle. The true angle of each hole was measured using a digital goniometer. Results Greater drilling accuracy was achieved at angles closer to 90°. An error of ≤±4° was achieved by 84.5 per cent of participants drilling a 90° angle compared with approximately 20 per cent of participants drilling a 30–45° angle. There was no effect of surgeon experience, task repetition or drill bit size on the mean error for intended versus achieved angle. Increased perception of difficulty was associated with the more acute angles and decreased accuracy, but not experience level. Clinical significance This study shows that surgeon ability to drill accurately (within ±4° error) is limited, particularly at angles ≤60°. In situations where drill angle is critical, use of computer-assisted navigation or custom-made drill guides may be preferable. PMID:27547423

Hip surgeries count to the most frequent orthopaedic operations in older patients. Nonelective surgeries for hip fractures cause substantial economic burden because of high costs of medical treatment and high associated mortality. Surgery for hip fracture in the elderly comorbid patient still presents a challenge to orthopaedic surgeons. It is recommended that this surgery is performed within 48 hours after sustaining the hip fracture to decrease mortality. Yet the recommended early surgery (i.e. 48 hours after the incident) is not always feasible due to the frequent overall frailty of the patients or conditions of concomitant disease. The care of patients unfit for early surgery has been not adequately addressed in the literature. We have previously introduced an algorithm based on ASA-PS and P-POSSUM scores to stratify elderly comorbid patients for early vs delayed hip surgery, and used principles of Damage Control Orthopaedics to minimized negative sequelae of surgery delay (Dong C et al., PLoS One 2016). In this paper, we elaborate on Damage Control Orthopaedics and the proposed approach in the context of frequent comorbidities in the elderly orthopaedic patients. Further studies on this subject are urgently needed to establish international consensus on hip fracture surgery delayed due to overall patient frailty or extensive comorbidities. PMID:27383299

Objectives The aim of our study was to determine the association between admitting service, medicine or orthopaedics, and length of stay (LOS) for a geriatric hip fracture patient. Design Retrospective. Setting Urban level 1 trauma center. Patients/Participants Six hundred fourteen geriatric hip fracture patients from 2000 to 2009. Interventions Orthopaedic surgery for geriatric hip fracture. Main Outcome Measurements Patient demographics, medical comorbidities, hospitalization length, and admitting service. Negative binomial regression used to determine association between LOS and admitting service. Results Six hundred fourteen geriatric hip fracture patients were included in the analysis, of whom 49.2% of patients (n = 302) were admitted to the orthopaedic service and 50.8% (3 = 312) to the medicine service. The median LOS for patients admitted to orthopaedics was 4.5 days compared with 7 days for patients admitted to medicine (P medicine (n = 92, 29.8%) than for those admitted to orthopaedics (n = 70, 23.1%). After controlling for important patient factors, it was determined that medicine patients are expected to stay about 1.5 times (incidence rate ratio: 1.48, P medicine service compared with the orthopaedic service increases a geriatric hip fractures patient’s expected LOS. Since LOS is a major driver of cost as well as a measure of quality care, it is important to understand the factors that lead to a longer hospital stay to better allocate hospital resources. Based on the results from our institution, orthopaedic surgeons should be aware that admission to medicine might increase a patient’s expected LOS. PMID:26371621

The preparticipation evaluation (PPE) is a widely used tool for detecting health conditions that may delay or disqualify athletic participation. The medical interview is the most valuable tool for identifying athletes who may be at increased risk for injury. Physical examination is tailored to identifying cardiac abnormalities or factors that may place an athlete at increased risk for injury. Although practiced in Europe, universal cardiac screening with electrocardiography is not currently recommended in the United States largely due to the high rate of false-positive results. Neuropsychological testing for management of concussion and laboratory testing for sickle cell trait may be indicated in select groups of athletes. Health care providers should view the PPE as a chance for anticipatory guidance and athlete-directed health counseling. Despite widespread acceptance of the PPE, the quality of such examinations varies significantly, which is an area for possible improvement and further research. PMID:26330569

Abstract Background :Accidental needle-stick injuries (NSIs) are a hazard for health-care workers and general public health. Orthopaedic surgeons may be more prone to NSIs due to the prevalence of bone spikes in the operative field and the use of sharp orthopaedic instruments such as drills, saws and wires. A hospital-based cross sectional study was conducted in the orthopedic wards of Melaka General Hospital. The prevalence of NSIs was 32 (20.9%) and majority of it occurred during assisting ...

This study surveyed plastic surgeons for the purpose of identifying gender-related differences within the specialty. A confidential 108-item questionnaire was mailed to all female members and candidates of the American Society of Plastic and Reconstructive Surgeons (ASPRS) and to an equal number of male colleagues. The survey was conducted between September of 1992 and October of 1993 using a modified Dillman five-step computerized method. The response rate was 73 percent for women (157 of 216) and 57 percent for men (124 of 216). Of those who responded, 65 percent of women and 89 percent of men were married (p delaying childbearing until they had begun full-time practice of plastic surgery (p < 0.001). No significant gender-related differences were noted with respect to medical school rank, training history, advanced degrees, subspecialty practiced, hospital affiliation, or hours worked. Women surgeons in academic practice held lower rank than men and were less likely to be tenured (p < 0.04). Gross annual income was lower for women (p < 0.001). In contrast to men (27 percent), most women (89 percent) perceived sexual discrimination and harassment (p < 0.001). The majority of plastic surgeons were satisfied with their financial situation (80 percent), work (94 percent), and family life (76 percent). Over 90 percent of both women and men were happy with their career choice and would encourage medical students to become surgeons. Plastic surgeons do not differ in training or professional practice characteristics. Discrimination and harassment and unequal promotion and remuneration of women in the university environment are problems that need to be eliminated. PMID:9030134
Fluoroscopy is frequently used in orthopaedic surgery, particularly in a trauma setting. Exposure of patients and staff to ionising radiation has been studied extensively; however, little work has been done to evaluate current knowledge and practices among orthopaedic trainees.

While the quality and efficiency of out-patient orthopaedic referrals are well documented in the literature, there is little on the standard and appropriateness of inpatient orthopaedic consultations.
Full Text Available Over the past half-century, biomaterials have been used in orthopaedic surgery world widely, but orthopaedic implant-associated infections (OIAIs are still a puzzle for orthopaedic surgeons, which may result in prolonged hospitalisation, poor functional status and high costs. The presence of implants increases the risk of microbial infection; moreover, the formation of bacterial biofilm leads to a higher resistance to antibiotics and local immune response. In such cases, conventional systemic delivery of drugs seems to be fairly inefficient and out-dated. Owing to this, debridement and/or removing the implant always become the only solution. Hence, it needs a simple, minimally invasive and effective therapy to eradicate the problem. There are abundant evidences showing that extracorporeal shock wave therapy (ESWT has favourable effects on stimulating callus formation, inducing angiogenesis, promoting osteogenesis and relieving pain. Studies also indicated that ESWs have a significant bactericidal effect on bacterial strains of bone- and implant-associated infections. Therefore, a hypothesis proposed herein is that ESWT may well be an effective adjuvant treatment for OIAI by controlling infection, inducing bone regeneration and promoting re-osseointegration.

A mentor serves as role model, counselor, and advocate for an understudy or protégé. The art and science of mentoring have been investigated most thoroughly in the educational literature, yet there are unique situational and individual considerations in the surgical arena that may warrant special consideration. The general attributes of successful mentors are not foreign to academic surgeons but may require deliberate cultivation to optimize mentorship in the context of academic medicine. Moreover, the stages of productive mentoring may be counter to the learned adaptive behaviors and instinctive personality traits of some accomplished surgeon educators. Indeed, examples of failed mentorship are common in our medical centers and, specifically, in surgical training programs. The behavioral adaptation that supports surgical decision-making under conditions of incomplete data and unusual stress often devalues succession planning and derivation of satisfaction from the success of other members of the team. Accordingly, fostering effective mentoring relationships in academic surgery will require a concerted effort to develop appropriate behaviors conducive to the mentoring process. The personal and professional growth of our students as well as the succession planning for our specialty are dependent upon the successful creation of an environment conducive to mentoring in academic orthopaedics.

British Trainees have gradually had their working week curtained over the last 8 years. The Republic of Ireland Trainees have not been subjected to the European Working Time Directive prior to 2009 and have therefore worked on average, more hours than their British counterparts. We wanted to see if the differing schemes had an impact on recruiting and training orthopaedic surgeons. We surveyed Republic of Ireland orthopaedic specialist registrars (SpRs) and North West (NW) British SpRs\\/specialist trainees (ST3 and above) to see if there were any discernable differences in working patterns and subsequent training exposure. A standard proforma was given to Irish Trainees and to NW SpRs\\/STs at their National or regional teaching (January\\/February 2009). 62% of Irish and 47% of British NW Trainees responded. Irish trainees were more likely to have obtained a post-graduate degree (p = 0.03). The Irish worked more hours per week (p < 0.001) doing more trauma operative lists (p = 0.003) and more total cases per 6 months than the NW British (p = 0.003). This study suggests that more hours worked, equals more operative exposure, without detriment to the academic side of training. Obviously it is not possible to say whether fewer operations make for a poorer surgeon, but the evidence suggests that it may be true.

Every year, hundreds of new surgeons graduate from residency programs across Canada. Much time and effort is spent on preparing these surgeons for independent practice, but there is little literature about the career trajectories of surgeons after they finish training and enter practice. We surveyed all surgeons graduating from the residency programs of a single Canadian medical school over 25 years (1985–2010). Most respondents rated their job satisfaction as high/very high and indicated they would still pursue a residency in surgery and/or their specialty if they had it to do over again. This commentary discusses important information about where our graduates go and what their careers are like, challenging existing stereotypes about careers in surgery. Our survey findings should be communicated to students interested in careers in surgery. PMID:26384145

Subtalar dislocations were first described in 1811 as the simultaneous dislocation of the talo-calcaneal and talo-navicular joints without any tibio-talar or talar neck associated fractures. They were classified in 1853 as: medial, lateral, posterior and anterior based on the displacement of the foot in relationship to the talus. These are uncommon injuries, representing approximately 1 % of all traumatic injuries of the foot and 1-2 % of all dislocations, being associated with high energy trauma.Closed reduction of these dislocations should be performed as early as possible to avoid further damage to the skin and neurovascular structures. If this is not possible, then open reduction without further delay is recommended. Irreducible injuries have been reported in 0 to 47 % of cases. Open dislocations represent between 46 and 83 % of all cases, and have been associated with poor prognosis. Associated fractures have a high incidence, the most frequent ones are the posterior process of the talus, talar head, external malleolus, medial malleolus and the tubercle of the fifth metatarsal.These types of injuries are not faced by orthopaedic surgeons on a daily basis and having a source of information on how to manage and what to expect is important. We present an up-to-date literature review on the epidemiology, clinical presentation, radiologic assessment, treatment options and prognostic factors of these uncommon injuries. PMID:26208589

Osteogenesis imperfecta is a heritable group of collagen-related disorders that affects up to 50,000 people in the United States. Although the disease is most symptomatic in childhood, adults with osteogenesis imperfecta also are affected by the sequelae of the disease. Orthopaedic manifestations include posttraumatic and accelerated degenerative joint disease, kyphoscoliosis, and spondylolisthesis. Other manifestations of abnormal collagen include brittle dentition, hearing loss, cardiac valve abnormalities, and basilar invagination. In general, nonsurgical treatment is preferred for management of acute fractures. High rates of malunion, nonunion, and subsequent deformity have been reported with both closed and open treatment. When surgery is necessary, surgeons should opt for load-sharing intramedullary devices that span the entire length of the bone; locking plates and excessively rigid fixation generally should be avoided. Arthroplasty may be considered for active patients, but the procedure frequently is associated with complications in this patient population. Underlying deformities, such as malunion, bowing, rotational malalignment, coxa vara, and acetabular protrusio, pose specific surgical challenges and underscore the importance of preoperative planning.

Benchmark trials in orthopaedics are designed to address a question of substantial interest to clinicians and patients. They are also designed to have prospective data collection, an adequate sample size, an appropriate duration of follow-up based on the injury or treatment under study, blinded adjudication of the outcome variables, appropriate statistical analyses, and widespread and effective dissemination of the information learned in the trial. There are multiple lessons to be gleaned from these trials: (1) Identifying an engaging and relevant clinical question will make it easier to identify centers that are willing to participate. (2) Individual site leadership, both of the overall project and at the individual site, is critical to the success of any trial. (3) Not every trial needs to have a randomized design; observational trials can provide data that will impact clinical care. (4) Patients should understand the long-term goals of the project when they are enrolled so that they have a sense of the importance of their role in the study. (5) Follow-up rates that are >90% are possible for orthopaedic trials, but effort and money are required to achieve this. (6) Patients who do not agree to be randomized should be enrolled as subjects in a parallel observational design if it is available. (7) Blinded adjudication of the outcome variables is recommended whenever feasible. (8) Partnership with the academic community is mandatory for the success of industry-funded, phase-3 United States Food and Drug Administration trials. (9) Intention-to-treat analysis and as-treated analysis should be reported. Benchmark orthopaedic trials can and will change clinical practice, but detailed planning must occur to ensure that the results are believable and relevant to the orthopaedic community. These trials are time-consuming and expensive, but with the use of careful initial planning and continued oversight during the trial, Level-I evidence will be obtained and will be useful

Many orthopaedic implants are composed of alloys containing chromium. Of particular relevance is the increasing number of Cobalt Chromium bearing arthroplasies being inserted into young patients with osteoarthritis. Such implants will release chromium ions. These patients will be exposed to the released chromium for over 50 years in some cases. The subsequent chromium ion metabolism and redistribution in fluid and tissue compartments is complex. In addition, the potential biological effects o...

Academic surgeons should be aware of the tremendous potential that exists to partner with private companies on projects relating either to basic or clinical research. This is particularly timely now because many of these companies are experiencing unprecedented growth and market valuation. The development of these relationships requires knowing who to deal with as well as how to negotiate. Most academic medical centers have individuals who have expertise in developing sponsored research agreements, and young investigators should take advantage of this expertise. PMID:10727959

We describe the implementation process of hip prostheses selection in the Netherlands. The recent problems with large head metal-on-metal hip prostheses resulted in substantial damage to the surgeons' credibility and reputation in the media. This led to a true sense of urgency among orthopaedic surgeons to increase their activities to secure patient safety. The board of the Dutch Orthopaedic Association (NOV) in the Netherlands established a Dutch Hip Task Force (DHTF) with the explicit assignment of formulating criteria to classify the quality of total hip implants on the Dutch market based on survivorship. The aim was to offer unequivocal information enabling a balanced choice of total hip prosthesis. The ultimate goal of the NOV is that all implanted total hip prostheses implanted in the Netherlands are based on reliable clinical evidence. The DHTF decided to adapt the principles of the National Institute for Health and Care Excellence (NICE, UK) (www.nice.org.uk). The taskforce uses data from the registries as well as the Orthopaedic Data Evaluation Panel (ODEP). If the ODEP guidelines had been chosen as standard alone, one quarter of our listed hip components would not have been included. In our view this underlines the strength in the Dutch approach where high quality registry data and ODEP ratings are complementary and result in a list of reliable hip prostheses. Most importantly we offer patients insights into the known quality of the implants by sharing the results of our implant review. This will facilitate shared decision making by empowering patients in their knowledge on available hip arthroplasties. PMID:25633758
@@ With the development of medical science,orthopaedic traumatology, which derives from orthopaedics, becomes an important sub-discipline.Orthopedic traumatology includes: (1) fracture of limbs and spine; (2) injury to blood vessels, nerves, muscles and tendons; (3) traumatic skin defects of the limbs; (4)the limb injury and spinal cord injury, etc. Since the end of the 20th century, the orthopaedic tranmatology field has been developing rapidly, and is becoming one of the four major sub-groups of orthopaedics along with musculoskeletal and tumor surgery, spinal surgery, and joint surgery. 1-4

Full Text Available Abstract Background Orthopaedic injury is the most common reason for lameness and wastage in sport and leisure horses. Studies on racehorses have shown differences in injury risk between trainers and training strategies. The aim was to study between riding school variation in orthopaedic health status by clinical examination and horses age, and control for change of examiner, in schools with previous high (n = 4 and low (n = 4 insurance utilisation. Methods Horses (n = 99 at 8 riding schools were examined for conformation, movement in all gaits, standing flexion tests and palpation by two veterinary surgeons (in some schools only one. Indexes of findings were created for total health, movements, limbs, conformation and back palpation. Results Logistic regression analyses showed that findings increased with age (walk, trot, canter, conformation left hind limb, palpation fore limbs, hooves and flexion tests or decreased with age (conformation right fore limb. Significant differences in findings were found between riding schools and examiner for seven and eight criteria each (partly overlapping. Increasing indexes were significantly associated with one examiner (total health, movements, back palpation, increasing age (total health, movements or more time at the school (limbs. The back palpation index was highest at 5 Conclusion The age distribution differed markedly between riding schools and age affected several types of findings. This, combined with the two opposite groups of insurance use, shows that schools with low insurance utilisation had previously been able to "avoid" using the insurance, maybe even on similar types of cases if these were more promptly/differently handled indicating differential coverage of disease data in the insurance database. The examiner effect was clearly demonstrated. For some findings, the amount of clinical observations differed by school, even when examiner and age was adjusted for. Most findings were of minor
Full Text Available As the cost of healthcare continue to rise, orthopaedic surgeons are being pressured to practice cost-effective healthcare. Consequently, economic evaluation of treatment options are being reported more commonly in medical and surgical literature. As new orthopaedic procedures and treatments may improve patient outcome and function over traditional treatment options, the effect of the potentially higher costs of new treatments should be formally evaluated. Unfortunately, the resources available for healthcare spending are typically limited. Therefore, cost-effectiveness analyses have become an important and useful tool in informing which procedure or treatment to implement into practice. Cost-effectiveness analysis is a type of economic analysis that compares both the clinical outcomes and the costs of new treatment options to current treatment options or standards of care. For a clinician to be able to apply the results of a cost-effectiveness analysis to their practice, they must be able to critically review the available literature. Conducting an economic analysis is a challenging process, which has resulted in a number of published economic analyses that are of lower quality and may be fraught with bias. It is important that the reader of an economic analysis or cost-effectiveness analysis have the skills required to properly evaluate and critically appraise the methodology used before applying the recommendations to their practice. Using the principles of evidence-based medicine and the questions outlined in the Journal of the American Medical Association′s Users′ Guide to the Medical Literature, this article attempts to illustrate how to critically appraise a cost-effectiveness analysis in the orthopaedic surgery literature.

Antiplatelet agents are widely prescribed for the primary and secondary prevention of cardiovascular events. A common clinical problem facing orthopaedic and trauma surgeons is how to manage patients receiving these agents who require surgery, either electively or following trauma. The dilemma is to balance the risk of increased blood loss if the antiplatelet agents are continued peri-operatively against the risk of coronary artery\\/stent thrombosis and\\/or other vascular event if the drugs are stopped. The traditional approach of stopping these medications up to two weeks before surgery appears to pose significant danger to patients and may require review. This paper covers the important aspects regarding the two most commonly prescribed antiplatelet agents, aspirin and clopidogrel.

Glove perforation during surgery has always been a matter of concern as it increases the infection rate and the risk of transmission of blood borne diseases. To determine the common causes, the site and the awareness of glove perforations in orthopaedic surgery, a prospective study was conducted to assess the rate of glove perforation during 130 consecutive orthopaedic operations. All gloves worn by the surgical team were assessed after the surgery using the water-loading test. A total of 1452 gloves were tested, and the rate of perforation was 3.58%. Most of these perforations (61.5%) were unnoticed. The main surgeons had the most perforations (76.9%), followed by first assistants (13.5%) and second assistants (9.6%). Most perforations occurred at the non-dominant hand. The commonest site of perforation was the index finger followed by the thumb. Shearing force with instruments accounted for 45% of the noticed perforations. Majority of these occurred during nailing procedures (33%) and internal fixation without the use of wires (19%). Our rate of glove perforation is similar to other series. Most of them went unnoticed and were mainly due to shearing injuries rather than perforation by sharps. Therefore, there is an increased risk of contamination and break in asepsis during surgery. PMID:17605178

Increasing attention has been placed on providing higher quality and safer patient care. This requires the development of a new set of competencies to better understand and navigate the system and lead the orthopaedic team. While still trying to learn and develop these competencies, the academic orthopaedist is also expected to model and teach them.The orthopaedic surgeon must understand what is being measured and why, both for purposes of providing better care and to eliminate unnecessary expense in the system. Metrics currently include hospital-acquired conditions, "never events," and thirty-day readmission rates. More will undoubtedly follow.Although commitment and excellence at the individual level are essential, the orthopaedist must think at the systems level to provide the highest value of care. A work culture characterized by respect and trust is essential to improved communication, teamwork, and confidential peer review. An increasing number of resources, both in print and electronic format, are available for us to understand what we can do now to improve quality and safety.Resident education in quality and safety is a fundamental component of the systems-based practice competency, the Next Accreditation System, and the Clinical Learning Environment Review. This needs to be longitudinally integrated into the curriculum and applied parallel to the development of resident knowledge and skill, and will be best learned if resident learning is experiential and taught within a genuine culture of quality and safety.

Full Text Available Bone drilling is a common procedure to prepare an implant site during orthopaedic surgery. An increase in temperature during such a procedure can result in thermal ostenecrosis which may delay healing or reduce the stability of the fixation. Therefore it is important to minimize the thermal invasion of bone during drilling. The Taguchi method has been applied to investigate the optimal combination of drill diameter, feed rate and spindle speed in dry drilling of Polymethylmethacrylate (PMMA for minimizing the temperature produced.

Introduction Patients receiving musculoskeletal allografts may be at risk of postoperative infection. The General Medical Council guidelines on consent highlight the importance of providing patients with the information they want or need on any proposed investigation or treatment, including any potential adverse outcomes. With the increased cost of defending medicolegal claims, it is paramount that adequate, clear informed patient consent be documented. Methods We retrospectively examined the patterns of informed consent for allograft bone use during elective orthopaedic procedures in a large unit with an onsite bone bank. The initial audit included patients operated over the course of 1 year. Following a feedback session, a re-audit was performed to identify improvements in practice. Results The case mix of both studies was very similar. Revision hip arthroplasty surgery constituted the major subgroup requiring allograft (48%), followed by foot and ankle surgery (16.3%) and revision knee arthroplasty surgery (11.4%) .On the initial audit, 17/45 cases (38%) had either adequate preoperative documentation of the outpatient discussion or an appropriately completed consent form on the planned use of allograft. On the re-audit, 44/78 cases (56%) had adequate pre-operative documentation. There was little correlation between how frequently a surgeon used allograft and the adequacy of consent (Correlation coefficient -0.12). Conclusions Although the risk of disease transmission with allograft may be variable, informed consent for allograft should be a routine part of preoperative discussions in elective orthopaedic surgery. Regular audit and feedback sessions may further improve consent documentation, alongside the targeting of high volume/low compliance surgeons. PMID:26924483

Full Text Available An epidemiological study was undertaken to study the incidence and distribution of orthopaedic manifestations of filariasis in an endemic area. A total of 207 cases were clinically examined and investigated. Patients were divided into three groups , viz., Group A: Orthopaedic manifestations with no history of filariasis . Group B: Orthopaedic manifestations with history of filariasis such as microfilaraemia or filarial fevers etc., Group C: Orthopaedic manifestations with chronic manifestations such as elephantiasis, hydrocele etc. To confirm filarial etiology, all the cases were examined for the presence of filarial antibody by indirect ELISA using wuchereda bancrofti microfilarial excretory- secretary antigen (wd Mf ESAg . A total of 61 of 102 patients of Group A, 14 of 21 patients of group B, and 73 of 84 patients of Group C were positive for filarial antibody. This study showed the prevalence of filarial antibody in about 71.4% of various orthopaedic manifestations.

This paper presents a summary of our work on the functional behavior of polymethylmethacrylate as a fixation material for load-bearing implants. Experimental tests on models of hip reconstructions have shown that damage accumulation, in the form of growth of numerous microcracks, occurs in cement-fixated orthopaedic implants. To predict failure due to damage accumulation, fatigue tests of hand-mixed and vacuum-mixed cement are used to determine a relationship between the probability-of-failure, stress, and porosity of the cement. This relationship is then applied to the comparative analysis of orthopaedic implants using finite element analysis. Two implant systems are considered: femoral hip prostheses and glenoid replacement prostheses. It is shown how the complex and intricate stress patterns in the polymethylmethacrylate cement 'mantles' can be analyzed in terms of the probability-of-failure. This allows comparison of implants for pre-clinical testing purposes. The results complement those obtained from clinical studies where subsidence of the implant correlates with implant loosening [Karrholm et al. J. Bone Jt. Surg. Vol. 76B (1994) 912-916]. If subsidence is due to creep, then a correlation between damage accumulation and creep should exist. A basis for such a correlation in polymethylmetacrylate is proposed that links clinical findings of subsidence with our results with regard to damage accumulation. (orig.)

Morrison argued that demography, economy, and technology drive the evolution of industries from a formative first-generation state ("First Curve") to a radically different way of doing things ("Second Curve") that is marked by new skills, strategies, and partners. The current health-reform movement in the United States reflects these three key evolutionary trends: surging medical needs of an aging population, dramatic expansion of Medicare spending, and care delivery systems optimized through powerful information technology. Successful transition from a formative first-generation state (First Curve) to a radically different way of doing things (Second Curve) will require new skills, strategies, and partners. In a new world that is value-driven, community-centric (versus hospital-centric), and prevention-focused, orthopaedic surgeons and health-care administrators must form new alliances to reduce the cost of care and improve durable outcomes for musculoskeletal problems. The greatest barrier to success in the Second Curve stems not from lack of empirical support for integrated models of care, but rather from resistance by those who would execute them. Porter's five forces of competitive strategy and the behavioral analysis of change provide insights into the predictable forms of resistance that undermine clinical and economic success in the new environment of care. This paper analyzes the components that will differentiate orthopaedic care provision for the Second Curve. It also provides recommendations for future-focused orthopaedic surgery and health-care administrative leaders to consider as they design newly adaptive, mutually reinforcing, and economically viable musculoskeletal care processes that drive the level of orthopaedic care that our nation deserves-at a cost that it can afford.

For bone regeneration, there is need for biodegradable, synthetic scaffolds that direct the formation of de novo mineralized tissue. Orthopaedic implants additionally require mechanical function. The work described herein attempts to address both of these needs. The general strategy involves integrating molecularly designed tissue engineering scaffolds with porous metallic foams to create hybrid materials to direct cellular behavior. Peptide amphiphiles (PAs) that self-assemble into nanofibers were designed to template hydroxyapatite mineral under biological conditions. The molecular design incorporated either serine (S) or phosphoserine S(P) and was mixed with RGDS-bearing PA to evaluate of the key parameters for mineral formation. This led to the discovery of nanoscale hydroxyapatite spheres templated on both S- and S(P)-bearing PA nanofibers. Stem cells were encapsulated in these gels and RT-PCR showed osteoblastic differentiation in all samples. Osteoblast maturation was increased in S-bearing PA compared to S(P)-bearing PA, although the reason is not yet understood. A method to create robust PA nanofiber coatings on NiTi was developed by optimizing the NiTi oxide surface chemistry, optimizing silane vapor deposition, and covalently attaching the PAs to the silanized substrate. The surfaces were characterized by XPS, SIMS, AFM, and fluorimetry. In vitro experiments demonstrated the importance of covalent attachment for cellular adhesion and proved the materials were not cytotoxic. Orthopaedic hybrid materials were created by triggering PA self-assembly within the interconnected pores of Ti foams developed by the Dunand research group. In vitro experiments demonstrate that pre-osteoblasts adhere to, proliferate on, and migrate into PA-Ti hybrids made with S(P)- and RGDS-bearing PA mixtures. The cells differentiate into mature osteoblasts and remain viable up to 28 days. In vivo studies using a rat model demonstrate osteointegration and boney ingrowth into bare

Since the days of Sushruta, innovation has shaped the history of plastic surgery. Plastic surgeons have always been known as innovators or close followers of innovations. With this descriptive international survey study, the authors aimed to evaluate the future of plastic surgeons by analyzing how plastic surgery and plastic surgeons will be affected by new trends in medicine. Aesthetic surgery is the main subclass of plastic surgery thought to be the one that will change the most in the future. Stem cell therapy is considered by plastic surgeons to be the most likely "game changer." Along with changes in surgery, plastic surgeons also expect changes in plastic surgery education. The most approved assumption for the future of plastic surgery is, "The number of cosmetic nonsurgical procedures will increase in the future." If surgeons want to have better outcomes in their practice, they must at least be open minded for innovations if they do not become innovators themselves. Besides the individual effort of each surgeon, international and local plastic surgery associations should develop new strategies to adopt these innovations in surgical practice and education.

The clinical and scientific level of Japanese surgeons leads the world needless to say, in the field of early gastric cancer, supported by double-contrast roentgenogram, endoscopy and surgical procedure including lymph node dissection with good outcomes. Surgical skills of Japanese surgeons have been improved by watching of cine or videotaped programs at the academic assemblies, breaking through apprenticeship. Ambitious young surgeons could freely learned excellent technical procedure from the pictures. Young surgeon must be an ever-thinking surgeon to get any hint on the film. Even though medical examinations and treatments including surgical procedures are on the way of standardization through EBM, manuals, guidelines and DPC payment system, medical doctors including surgeons must critically continue to think and seek for better treatment for the patients. Since the every patient differs in terms of age. sex, stage of disease, complicated conditions and social background, the treatment should be different, patient to patient, as tailor made fashion. Unless any progress is made, science and arts of medicine will decline. As another advice for a young surgeon from my experience you should write an operation protocol of every procedure by your self, even if that operation is the first experience or you joined as an assistant. After you wrote, you read the protocol by your instructor. Then you learn many knowledge and surgical know-how. Certainly, the book of the protocols will be your valuable treasure. Furthermore, you should not aim to be a skillful surgeon, but to be a good surgeon performing reliable and gentle operations for the patients. PMID:15176525

Annual surgeon case volume has been linked to patient outcome in a variety of surgical fields, although limited data focus on gynecologic surgery performed by general gynecologists. Herein we review the literature addressing the associations between intraoperative injury, postoperative morbidity, and resource use among surgeons performing a low vs high volume of hysterectomies. Although study design and populations differ, individual and composite morbidity outcomes consistently favored high-volume surgeons. Given the growing emphasis on competency-based evaluation in surgery, gynecology departments may soon consider volume requirements a component of privileging. PMID:23622760

Although the clinical picture and the natural progression of Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) differ, borderline forms exist. Classical orthopaedic treatment is based on self-rehabilitation (by the parents and the patient), physical therapy, posture alignment with orthotics, ergotherapy to set up technical aides, notably positioning in an electric wheelchair to provide more satisfactory autonomy. The functional aspect predominates over pure orthopaedics. Although surgical indications have evolved for the lower limbs, pelvic-spinal arthrodesis for treatment of scoliosis remains the reference treatment, but the methods have evolved since the advent of corticotherapy for DMD. Corticotherapy slows the progression of motor deficits, the age at which walking ability is lost is delayed (shifting from 10 years to 13-14 years depending on the studies), scoliosis progresses later, respiratory insufficiency is better controlled, and therefore survival is prolonged (between 20 and 40 years). However, although this functional aspect seems to respond better to the progress in overall treatment, it also results from a multidisciplinary approach to the disease. Nevertheless, assessment is required, not at a time t as reflected by the scales currently in use, but during daily activities as proposed by qualitative and quantitative monitoring seeking to model nyctohemeral functional motor skills. The principle is to characterize the type of activity (sitting, standing, lying down, walking), its duration, its intensity (walking speed), its frequency (number of activity changes, number of walking episodes), and their sequence (temporal sequence, organization of activity variation). The goal is to identify the variety of functional motor skills and their occurrence over time to determine whether treatment contributes a functional benefit and whether this benefit is put into practice daily.

Full Text Available Abstract Background Evidence-based medicine posits that health care research is founded upon clinically important differences in patient centered outcomes. Statistically significant differences between two treatments may not necessarily reflect a clinically important difference. We aimed to quantify the sample sizes and magnitude of treatment effects in a review of orthopaedic randomized trials with statistically significant findings. Methods We conducted a comprehensive search (PubMed, Cochrane for all randomized controlled trials between 1/1/95 to 12/31/04. Eligible studies include those that focused upon orthopaedic trauma. Baseline characteristics and treatment effects were abstracted by two reviewers. Briefly, for continuous outcome measures (ie functional scores, we calculated effect sizes (mean difference/standard deviation. Dichotomous variables (ie infection, nonunion were summarized as absolute risk differences and relative risk reductions (RRR. Effect sizes >0.80 and RRRs>50% were defined as large effects. Using regression analysis we examined the association between the total number of outcome events and treatment effect (dichotomous outcomes. Results Our search yielded 433 randomized controlled trials (RCTs, of which 76 RCTs with statistically significant findings on 184 outcomes (122 continuous/62 dichotomous outcomes met study eligibility criteria. The mean effect size across studies with continuous outcome variables was 1.7 (95% confidence interval: 1.43–1.97. For dichotomous outcomes, the mean risk difference was 30% (95%confidence interval:24%–36% and the mean relative risk reduction was 61% (95% confidence interval: 55%–66%; range: 0%–97%. Fewer numbers of total outcome events in studies was strongly correlated with increasing magnitude of the treatment effect (Pearson's R = -0.70, p Conclusion Our review suggests that statistically significant results in orthopaedic trials have the following implications-1 On average

With current technology, tissue-engineered skeletal muscle analogues (bioartificial muscles) generate too little active force to be clinically useful in orthopaedic applications. They have been engineered genetically with numerous transgenes (growth hormone, insulinlike growth factor-1, erythropoietin, vascular endothelial growth factor), and have been shown to deliver these therapeutic proteins either locally or systemically for months in vivo. Bone morphogenetic proteins belonging to the transforming growth factor-beta superfamily are osteoinductive molecules that drive the differentiation pathway of mesenchymal cells toward the chondroblastic or osteoblastic lineage, and stimulate bone formation in vivo. To determine whether skeletal muscle cells endogenously expressing bone morphogenetic proteins might serve as a vehicle for systemic bone morphogenetic protein delivery in vivo, proliferating skeletal myoblasts (C2C12) were transduced with a replication defective retrovirus containing the gene for recombinant human bone morphogenetic protein-6 (C2BMP-6). The C2BMP-6 cells constitutively expressed recombinant human bone morphogenetic protein-6 and synthesized bioactive recombinant human bone morphogenetic protein-6, based on increased alkaline phosphatase activity in coincubated mesenchymal cells. C2BMP-6 cells did not secrete soluble, bioactive recombinant human bone morphogenetic protein-6, but retained the bioactivity in the cell layer. Therefore, genetically-engineered skeletal muscle cells might serve as a platform for long-term delivery of osteoinductive bone morphogenetic proteins locally.

America is founded on high humanitarian, democratic ideals. The historic facts of slavery, discrimination, and segregation challenge and taint these democratic principles. Although progress has been made, serious racial problems remain. In 1997, the United States had 474 active hate groups, up 20% from 1996. African American males who have the same education as white males doing the same work earn approximately 75% of what their white counterparts earn. America, as predicted by the Kerner Commission Report, is two societies: black and white, separate, and unequal. Some astonishing disparities in healthcare exist. Peer reviewed medical literature documents that African Americans have higher infant mortality rates, shorter life expectancies, fewer joint replacements, and more amputations than whites. Communications within a diverse group of students and teachers enriches the educational experience. The late Supreme Court Justice Lewis Powell, LLD, asserted that a medical student from a particular background may enrich classmates' understanding of people whose cultures are different from their own, and improve their ability to serve a heterogeneous patient population. Diversity on clinical teams can enhance rapport between patient and physician, and can diminish unthinking insults to patients, born of physician ethnic insensitivity. Healthcare facilities with diverse staffs are more likely than homogeneous facilities to attract and successfully serve the nation's diverse population. A University of California at Davis School of Medicine study showed that diversity can be achieved without compromising quality of patient care. Clinically and ideologically, diversity in orthopaedics is good for patients and for the country. PMID:10335274

This paper presents a novel approach and its preliminary laboratory results for the employment of ultrasound (US) imaging in intraoperative guidance of computer-assisted orthopaedic surgeries (CAOS). The goal is to register live intraoperative US images with preoperative surgical planning data using minimal number of images. Preoperatively, a set of 2D US images are acquired with the corresponding positional information of the US probe provided by an optical tracking system. Using calibration parameters, the position of every pixel in the acquired images is transformed into the world coordinate frame to construct a 3D volumetric representation of the targeted anatomy for surgical planning. Intraoperatively, the surgeon takes live US images from the patient with the position of the US probe tracked in real time. A mutual-information-based registration algorithm is then used to find the closest match to the live image in the preoperative US image database. Because the position of the preoperative image inside the US volume is known, we are able to register the preoperative US volume to the live image, thus to the patient. Experiments have shown the registration algorithm has sub-millimeter accuracy in localizing the best match between the intraoperative and pre-operative images, demonstrating great potential for orthopaedic surgery applications. This method has some significant advantages over the previously reported US-guided CAOS techniques: it requires no segmentation, and employs only a few intraoperative images to accurately and robustly localize the patient. Preliminary laboratory results on both a Sawbones model of a radius bone and human subjects are presented.

The surgeon's daily workload renders him/her susceptible to a variety of the common work-related illness. They are exposed to a number of occupational hazards in their professional work. These hazards include sharp injuries, blood borne pathogens, latex allergy, laser plumes, hazardous chemicals, anesthetic gases, equipment hazards, static postures, and job related stressors. However, many pay little attention to their health, and neither do they seek the appropriate help when necessary. It is observed that occupational hazards pose a huge risk to the personal well-being of surgeons. As such, the importance of early awareness and education alongside prompt intervention is duly emphasized. Therefore, increased attention to the health, economic, personal, and social implications of these injuries is essential for appropriate management and future prevention. These risks are as great as any other occupational hazards affecting surgeons today. The time has come to recognize and address them. PMID:27103909

The delivery of high quality medical services is approaching a crisis situation in the United States. As physician reimbursements decline and overhead increases, orthopedic surgeons must seek additional sources of revenue to remain financially viable and control the quality of medical care that they deliver. The orthopedic surgeon group is well positioned to control its own service lines and deliver excellent patient care as a result. This article reviews the possibilities of multiple types of ancillary service lines available for the orthopedic group practice. PMID:18061762

Full Text Available Abstract Background Orthopaedic surgeons disagree considerably when classifying fractures of the proximal humerus. However, the clinical implications of low observer agreement remain unclear. The purpose of the study was to compare the agreement on Neer classification with the agreement on treatment recommendations. Methods We conducted a multi-centre observer-study. Five experienced shoulder surgeons independently assessed a consecutive series of 193 radiographs at two occasions three months apart. All pairs of radiographs were classified according to Neer. Subsequently, the observers were asked to recommend one of three treatment modalities for each case: non-operative treatment, locking plate osteosynthesis, or hemiarthroplasty. Results At both classification rounds mean kappa-values for inter-observer agreement on treatment recommendations (0.48 and 0.52 were significantly higher than the agreement on Neer classification (0.33 and 0.36 (p Conclusions We found a significantly higher agreement on treatment recommendations compared to agreement on fracture classification. The low observer agreement on the Neer classification reported in several observer studies may have less clinical importance than previously assumed. However, inter-observer agreement did not exceed moderate levels.

The health benefits of exercise may be attenuated by sports and recreation related injury (SRI). Though the majority of SRI are mild and self-limiting, a significant number are serious and require orthopaedic intervention. The aims of this study were to assess the burden of these serious injuries on the orthopaedic inpatient service, and to investigate potential target areas for injury prevention. All 1,590 SRI seen in the ED over a 3-month period were analysed using the Patient Information Management System to determine which patients received inpatient orthopaedic care. The medical records of those 63 patients who required inpatient care under orthopaedics were reviewed and data collected on demographic features, history, operative procedure and theatre resources, and length of hospital stay. Data were analyzed using SPSS. SRI accounted for 12.3% of all ED presentations. The principal activities resulting in injury requiring orthopaedic care were soccer, hurling and informal play e.g. trampoline. Falls made up 37% of the overall mechanism of injury but 68% of the injuries severe enough to require operative management. Most operative procedures were performed as part of a routine day trauma list but 20% were performed out of hours. This group of injuries places a significant burden on a busy trauma service. Injury prevention measures such as public education regarding falls in sport may have a role in reducing this burden.
Full Text Available Abstract Backround This retrospective study was undertaken to determine the incidence of kidney dysfunction (KD and to identify potential risk factors contributing to development of KD in orthopaedic population following an elective or emergency surgery. Methods A total of 1025 patients were admitted in our institution over a period of one year with various indications. Eight hundred and ninety-three patients (87.1% had a surgical procedure. There were 42 (52.5% male and 38 (47.5% female with a mean age of 72 years (range: 47 to 87 years. We evaluated the following potential risk factors: age, comorbidities, shock, hypotension, heart failure, medications (antibiotics, NSAIDs, opiates, rhabdomyolysis, imaging contrast agents and pre-existing KD. Results The overall incidence of KD was 8.9%. Sixty-eight patients developed acute renal injury (AKI and 12 patients developed acute on chronic kidney disease (CKD. In sixty-six (82.5% patients renal function was reversed to initial preoperative status. Perioperative dehydration (p = 0.002, history of diabetes mellitus (p = 0.003, pre-existing KD (p = 0.004, perioperative shock (p = 0.021 and administration of non-steroid anti-inflammatory drugs (NSAIDs (p = 0.028 or nephrotoxic antibiotics (p = 0.037 were statistically significantly correlated with the development of postoperative KD and failure to gain the preoperative renal function. Conclusion We conclude that every patient with risk factor for postoperative KD should be under closed evaluation and monitoring.

This study is a pilot effort towards the broader implementation of a national pediatric musculoskeletal trauma outcomes registry. The primary goal of this project is to explore the feasibility of a web-based data acquisition and management platform and to identify catalysts and obstacles to multi-center collaboration. A prospective cohort of children presenting to the Pediatric Emergency Departments with ankle, femur, supracondylar humerus, tibial spine, or open fractures at five clinical centers between October 2001 and March 2003 comprised the study population. Patients were enrolled via the treating orthopaedic resident, using a web-based data acquisition and management system. Orthopaedic attendees were sent an automated reminder to complete a follow-up form one week after treatment, and parents of enrolled children were sent child and parent health questionnaires by e-mail and mail in order to capture health-related quality of life and post-traumatic stress symptoms. A total of 299 patients were enrolled in the study with an average age of 7.3 years. Post-treatment follow-up questionnaires were completed by 39% of the attending orthopaedic surgeons, and by 43% of the enrolled patients or patient's parents. Children old enough to complete health questionnaires scored lower in 5 of 12 functional domains including Physical Function, Role/Social Emotional/Behavioral, Parental Impact-Emotional, Family Activities, and Family Cohesion. Within the subset of patients sustaining femur fractures whose parents completed health questionnaires, 9.5% reported significant post-traumatic stress symptoms. This study demonstrates the potential of a multi-center web-based registry to facilitate the collection of a rich array of pediatric trauma, treatment and patient-based outcomes data, although new regulatory issues regarding patient privacy pose challenges to such an approach.

To test how practice interruptions affect worker productivity, we estimate how temporal breaks affect surgeons' performance of coronary artery bypass grafting (CABG). Examining 188 surgeons who performed 56,315 CABG surgeries in Pennsylvania between 2006 and 2010, we find that a surgeon's additional day away from the operating room raised patients' inpatient mortality by up to 0.067 percentage points (2.4% relative effect) but reduced total hospitalization costs by up to 0.59 percentage points. Among emergent patients treated by high-volume providers, where temporal distance is most plausibly exogenous, an additional day away raised mortality risk by 0.398 percentage points (11.4% relative effect) but reduced cost by up to 1.4 percentage points. This is consistent with the hypothesis that as temporal distance increases, surgeons are less likely to recognize and address life-threatening complications. Our estimates imply additional intraprocedural treatment intensity has a cost per life-year preserved of $7871-18,500, well within conventional cost-effectiveness cutoffs. PMID:24973949

In the last part of the nineteenth century and beginning of the twentieth century surgeons at the University of Vienna helped transform the practice of surgery. They developed new more effective procedures, analyzed the results of their operations, promoted the emergence and growth of surgical specialties and sought understanding of tissue structure, physiology and pathophysiology. Their efforts made Vienna one of the world's most respected centres for operative treatment, basic and clinical research and surgical education. Two individuals, Adolf Lorenz (1854-1946) and Lorenz Böhler (1885-1973) focused their research and clinical practice on orthopaedics. During the same period in Germany Friedrich Pauwels (1885-1980) founded an orthopaedic institute and an engineering workshop in Aachen in 1913 and rapidly developed a lifelong interest in biomechanical influences: Using these theories, he achieved in 1927 healing of a non-union of the femoral neck by a re-orientation osteotomy, a condition considered to be incurable until this osteotomy and created his famous classification of fracture angles at the hip into Pauwels types I, II and III. The German orthopaedist Gerhard Küntscher (1900-1972) remained the most popular surgeon after the second war with his famous nail. PMID:26759255

Traditional continuing medical education (CME) depended primarily on periodic courses and conferences. The cost-effectiveness of these courses has not been established, and often the content is not tailored to best meet the needs of the students. Internet training has the potential to accomplish these goals. Over the last 10 years, we have developed a Web site entitled "Orthochina.org," based upon the wiki concept, which uses an interactive, case-based format. We describe the development of online case discussions, and various technical and administrative requirements. As of December 31, 2007, there were 33,984 registered users, 9,759 of which passed the confirmation procedures. In 2007, an average of 211 registrants visited daily. The average number of first page clicks was 4,248 per day, and the average number of posts was 70 per day. All cases submitted for discussion include the patient's complaint, physical examination findings, and relevant images based on specific criteria for case discussion. The case discussions develop well professionally. No spam posting or unauthorized personal advertisement is permitted. In conclusion, online academic discussions proceed well when the orthopaedic surgeons who participate have established their identities. PMID:18685911

Smartphones have the ability to benefit plastic surgeons in all aspects of patient care and education. With the sheer number of applications available and more being created everyday, it is easy to miss out on apps which could be of great relevance. Moreover, the range of android applications available has not been extensively discussed in the literature. To this end, we have compiled an exhaustive list of android smartphone applications, which we feel can help our day to day functioning. The apps have been extensively reviewed and neatly described along with all their potential uses. In addition, we have made an effort to highlight 'non-medical' or efficiency apps which can improve departmental functioning. These apps have not been described in prior articles, and their functionality might not be known to all. We believe that the technology savvy plastic surgeon can make maximum use of these apps to his benefit. PMID:25991890

There was increased sleep time during the day on call and...
The facial plastic surgeon potentially has a conflict of interest when confronted with the patients requesting surgery, due to the personal gain attainable by agreeing to perform surgery. The aim of this review is to discuss the potential harm the surgeon can inflict by carrying out facial plastic surgery, beyond the standard surgical complications of infection or bleeding. It will discuss the desire for self-improvement and perfection and increase in the prevalence facial plastic surgery. We address the principles of informed consent, beneficence and non-maleficence, as well as justice and equality and how the clinician who undertakes facial plastic surgery is at risk of breaching these principles without due care and diligence.

There is a clear discrepancy between the growth of cell therapy and tissue engineering research in orthopaedics over the last two decades and the number of approved clinical therapies and products available to patients. At the 2015 annual meeting of the Orthopaedic Research Society, a workshop was held to highlight important considerations from the perspectives of an academic scientist, clinical researcher, and industry representative with the aim of helping researchers to successfully translate their ideas into clinical and commercial reality. Survey data acquired from workshop participants indicated an overall positive opinion on the future potential of cell-based therapies to make a significant contribution to orthopaedic medicine. The survey also indicated an agreement on areas requiring improvement in the development of new therapies, specifically; increased support for fundamental research and education and improved transparency of regulatory processes. This perspectives article summarises the content and conclusions of the workshop and puts forward suggestions on how translational success of cell-based therapies in orthopaedics may be achieved.

The Military Orthopaedic Trauma Registry (MOTR) orginally began as part of the Department of Defense Trauma Registry (DoDTR) and became a live registry in 2013. As a quality improvement process, this study examined MOTR data for 20 female amputees compared with DoDTR data. The DoDTR provided diagnosis and procedure codes as a list but no details. The MOTR provided additional data, including specific limb, fracture classifications, and associated injuries per limb. The MOTR allowed for construction of a treatment time line for each limb, including number and timing of debridements, antibiotics, and implant types. Orthopaedic-specific complications were also coded more frequently in the MOTR and clearly identified with a specific injury and treatment.

Full Text Available Abstract Background Despite having access to medically necessary care available through publicly funded provincial health care systems, some Canadians travel for treatment provided at international medical facilities as well as for-profit clinics found in several Canadian provinces. Canadians travel abroad for orthopaedic surgery, bariatric surgery, ophthalmologic surgery, stem cell injections, “Liberation therapy” for multiple sclerosis, and additional interventions. Both responding to public interest in medical travel and playing an important part in promoting the notion of a global marketplace for health services, many Canadian companies market medical travel. Methods Research began with the goal of locating all medical tourism companies based in Canada. Various strategies were used to find such businesses. During the search process it became apparent that many Canadian business promoting medical travel are not medical tourism companies. To the contrary, numerous types of businesses promote medical travel. Once businesses promoting medical travel were identified, content analysis was used to extract information from company websites. Company websites were analyzed to establish: 1 where in Canada these businesses are located; 2 the destination countries and health care facilities that they market; 3 the medical procedures they promote; 4 core marketing messages; and 5 whether businesses market air travel, hotel accommodations, and holiday tours in addition to medical procedures. Results Searches conducted from 2006 to 2011 resulted in identification of thirty-five Canadian businesses currently marketing various kinds of medical travel. The research project began with what seemed to be the straightforward goal of establishing how many medical tourism companies are based in Canada. Refinement of categories resulted in the identification of eighteen businesses fitting the category of what most researchers would identify as medical tourism

We sought to prospectively document and evaluate the learning curve of an experienced extracapsular surgeon making a supervised transition from extracapsular cataract extraction (ECCE) to phacoemulsification. Over a period of 2 weeks, 51 phacoemulsification procedures using an endocapsular nucleofractis technique were performed by a single senior surgeon at the Christian Medical College in Vellore, India under the supervision of a visiting US expert with more than 15 years' experience in the technique. Vitreous loss occurred in seven eyes (six prior to the stage of cortical aspiration); failure of capsulorhexis necessitated conversion to standard ECCE in four. Injury to the inferior iris during phacoemulsification was cosmetically significant in three eyes. Two eyes had mild persistent localized corneal edema, but there were no instances of permanent corneal damage. One eye had intraoperative displacement of the nucleus into the vitreous. In one eye with vitreous loss, the implanted intraocular lens dislocated into the vitreous cavity. Two patients had clinically detectable cystoid macular edema at 6 weeks. Eleven patients were lost to follow up after 3 weeks. Six weeks after surgery, 36 of the remaining 40 eyes (90%) had achieved a best-corrected visual acuity of 6/6. We conclude that phacoemulsification requires supervised learning, even for an experienced surgeon. Complications still occurred, but were restricted to the unfamiliar steps of the surgery. Factors identified in the first 2 days of surgery (10 cases) as critical in the smooth transition to phacoemulsification were careful selection of initial cases, a successful capsulorhexis, and hydrodissection with vigorous nucleus mobilization.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7970530

BACKGROUND: Acute hepatobiliary pathology is a common general surgical emergency referral. Diagnosis requires imaging of the biliary tree by ultrasonography. The accuracy and impact of surgeon-performed ultrasonography (SUS) on the diagnosis of emergent hepatobiliary pathology was examined. METHODS: A prospective study, over a 6-month period, enrolled all patients with symptoms or signs of acute hepatobiliary pathology. Patients provided informed consent and underwent both SUS and standard radiology-performed ultrasonography (RUS). SUS was performed using a 2-5-MHz broadband portable ultrasound probe by two surgeons trained in ultrasonography, and RUS using a 2-5-MHz fixed unit. SUS results were correlated with those of RUS and pathological diagnoses. RESULTS: Fifty-three consecutive patients underwent 106 ultrasonographic investigations. SUS agreed with RUS in 50 (94.3 per cent) of 53 patients. SUS accurately detected cholelithiasis in all but two cases and no patient was inaccurately diagnosed as having cholelithiasis at SUS (95.2 per cent sensitivity and 100 per cent specificity). As an overall complementary diagnostic tool SUS provided the correct diagnosis in 96.2 per cent of patients. Time to scan was significantly shorter following SUS (3.1 versus 12.0 h, P < 0.05). CONCLUSION: SUS provides a rapid and accurate diagnosis of emergency hepatobiliary pathology and may contribute to the emergency management of hepatobiliary disease.

Composite bone models are increasingly used in orthopaedic biomechanics research and surgical education-applications that traditionally relied on cadavers. Cadaver bones are suboptimal for many reasons, including issues of cost, availability, preservation, and inconsistency between specimens. Further, cadaver samples disproportionately represent the elderly, whose bone quality may not be representative of the greater orthopaedic population. The current fourth-generation composite bone models provide an accurate reproduction of the biomechanical properties of human bone when placed under bending, axial, and torsional loads. The combination of glass fiber and epoxy resin components into a single phase has enabled manufacturing by injection molding. The high level of anatomic fidelity of the cadaver-based molds and negligible shrinkage properties of the epoxy resin results in a process that allows for excellent definition of anatomic detail in the cortical wall and optimized consistency of features between models. Recent biomechanical studies of composites have validated their use as a suitable substitute for cadaver specimens. PMID:24486757
Full Text Available A non-experimental, descriptive and quantitative survey was conducted to explore orthopaedic patients’ perceptions about the pre-operative information received when undergoing elective surgery in two hospitals in the KwaZulu-Natal Province. The findings indicate that most patients perceived the pre-operative information to be useful in their preparation for surgery. Aspects that were not addressed during preoperative information sessions included post-operative nutrition, pain medication, ambulation, deep breathing and coughing exercises. The recommendations include that all these aspects should be addressed in future pre-operative education sessions. Further research should be conducted for enhancing the pre-operative information provided to patients scheduled to undergo elective orthopaedic surgery.
Objective: To compare the pattern of adult inpatient orthopaedic injuries admitted at three Vancouver hospitals following one of the worst winter snowstorms in the region with the preceding control winter period. Methods: The surveillance study was conducted at the University of British Columbia, Vancouver, Canada, 2007 to 2010. Inpatient adult admissions for orthopaedic injuries at three hospitals were recorded, including age, gender, anatomic location of injury, type of fracture (open or closed), fixation method (internal versus external fixation), and length of acute care hospital stay. Comparisons between admissions during this weather pattern and admission during a previous winter with minimal snow were made. SPSS 19 was used for statistical analysis. Results: Of the 511 patients admitted under Orthopaedic trauma service during the significant winter snowstorms of December 2008 - January 2009, 100 (19.6%) (CI: 16.2%-23.2%) were due to ice and snow, whereas in the preceding mild winter only 18 of 415 (4.3%) (CI: 2.5%-6.8%) cases were related to snow (p<0.05). Ankle and wrist fractures were the most frequent injuries during the index snow storm period (p<0.05). At all the three institutions, 97 (96.5%) fractures were closed during the snowstorm as opposed to 17 (95%) during the control winter period. Internal fixation in 06 (89%) fractures as opposed to external fixation in 12 (11%) patients was the predominant mode of fixation across the board during both time periods. Conclusion: The study demonstrated a significantly higher inpatient orthopaedic trauma volume during the snowstorm more rigorous prospective studies need to be designed to gain further insight to solving these problems from a public health perspective.

Implant osseointegration is a prerequisite for clinical success in orthopaedic and dental applications, many of which are restricted by loosening. Biomaterial surface modification approaches, including calcium-phosphate ceramic coatings and macro/microporosity, have had limited success in promoting integration. To improve osseointegration, titanium surfaces were coated with the GFOGER collagen-mimetic peptide, selectively promoting α2β1 integrin binding, a crucial event for osteoblastic diffe...
Full Text Available Abstract Numerous orthopaedic injuries can follow a seizure and are often diagnosed late. This is the first documented case of a missed bilateral anterior shoulder dislocation following a seizure. The possible reasons for the greater incidence of posterior dislocations are examined and why bilateral anterior dislocations following a seizure are so rare. The article discusses the reasons for the delay and highlights potential pitfalls and learning points for junior emergency department doctors.

A wide ranging discussion about the factors that have influenced oil and natural gas prices, the differences of the Canadian market from international markets, the differences between eastern and western Canadian markets, and shareholders' perspectives on recent commodity price developments was presented. Developments in the OPEC countries were reviewed, noting that current OPEC production of 25 mmbbls is about 60 per cent higher than it was in 1985. It is expected that OPEC countries will continue to expand capacity to meet expected demand growth and the continuing need created by the UN embargo on Iraqi oil sales. Demand for natural gas is also likely to continue to rise especially in view of the deregulation of the electricity industry where natural gas may well become the favored fuel for incremental thermal generation capacity. Prices of both crude oil and natural gas are expected to hold owing to unusually low storage levels of both fuels. The inadequacy of infrastructure, particularly pipeline capacity as a key factor in the Canadian market was noted, along with the dynamic that will emerge in the next several years that may have potential consequences for Canadian production - namely the reversal of the Sarnia to Montreal pipeline. With regard to shareholders' expectations the main issues are (1) whether international markets reach back to the wellhead, hence the producer's positioning with respect to transportation capacity and contract portfolios, and (2) whether the proceeds from increased prices are invested in projects that are yielding more than the cost of capital. 28 figs

The dire challenges faced in Haiti, both preearthquake and postearthquake, highlight the need for developing surgical infrastructure to care for traumatic musculoskeletal injuries. The proposed Orthopaedic Trauma Care Specialist (OTCS) residency program aims to close the critical human resource gap that limits the appropriate care of musculoskeletal trauma in Haiti. The OTCS program is a proposal for a 2-year residency program that will focus primarily on the management of orthopaedic trauma. The proposed program will be a comprehensive approach for implementing affordable and sustainable strategies to improve orthopaedic trauma care. Its curriculum will be tailored to the injuries seen in Haiti, and the treatments that can be delivered within their health care system. Its long-term sustainability will be based on a "train-the-trainers" approach for developing local faculty to continue the program. This proposal outlines the OTCS framework specifically for Haiti; however, this concept is likely applicable to other low- and middle-income environments in a similar need for improved trauma and fracture care.

Full Text Available The use of oral corticosteroid (OCS drugs is advocated because of their potent anti-inflammatory effects. They also possess many potential adverse effects. No study has assessed physician prescribing practices of OCS therapy in high school (HS or college (COL athletes. This paper reports the prescribing patterns of sports medicine physicians who used short-term OCS therapy and to describe associated complications in HS and COL athletes within a 24- month period. An internet link to a descriptive epidemiology survey was included in an e-mail to all members of the Arthroscopy Association of North America and the American Orthopaedic Society for Sports Medicine. Descriptive statistics and correlation analysis were used to examine responses. Total response rate was 32% (615/1,928. Sixty-six percent of the physicians indicated prescribing OCS to both groups of athletes, while 29% reported prescribing OCS to COL athletes and 5% to HS athletes for musculoskeletal injuries. Physicians who prescribed multiple OCS regimens to the same athlete within the same season (P = 0.01 and physicians who prescribed OCS to the skeletally immature athlete (P = 0.009 reported more complications than other physicians. Among the 412 physicians who did not prescribe OCS in the treatment of athletic induced musculoskeletal injury, 251 (61% cited a risk of developing medical complications as the primary reason for avoiding use. The reported number of medical complications was low with no cases of avascular necrosis reported for the 2-year recall period. Orthopaedic surgeons who treated athletic induced musculoskeletal injuries with a short-term course of oral corticosteroids reported that high school and college athletes benefited with few medical complications

The demand for paediatric orthopaedic care is growing, and providing the service required is an increasingly challenging task. Physiotherapist-led triage clinics are utilised in adult orthopaedics to enable the provision of care to patients who may not require a surgical consult. The Physiotherapy Orthopaedic Triage Clinic (POTC) was established in Our Lady\\'s Children\\'s Hospital Crumlin in response to increasing demands on the paediatric orthopaedic service. The clinic is run by physiotherapists working in an advanced practice role (APP), and is the first paediatric clinic of its type and scale in the Republic of Ireland.
The National Research Council of Canada is establishing a coordinated national program of fusion research and development that is planned to grow to a total annual operating level of about $20 million in 1985. The long-term objective of the program is to put Canadian industry in a position to manufacture sub-systems and components of fusion power reactors. In the near term the program is designed to establish a minimum base of scientific and technical expertise sufficient to make recognized contributions and thereby gain access to the international effort. The Canadian program must be narrowly focussed on a few specializations where Canada has special indigenous skills or technologies. The programs being funded are the Tokamak de Varennes, the Fusion Fuels Technology Project centered on tritium management, and high-power gas laser technology and associated diagnostic instrumentation
On March 13 of 1991, the Prime Minister of Canada, Brian Mulroney and the President of the United States of America, George Bush, signed an Agreement on Air Quality. This agreement enshrines Principle 21 of the 1972 Stockholm Declaration which states that countries are to ensure that activities within their jurisdiction do not cause damage to the environment of another country. This agreement also includes provisions for controlling acid rain. The Agreement on Air Quality followed years of discussion between the two countries and is a significant milestone in the history of Canadian acid rain policy. This paper begins by describing Canadian acid rain policy and its evolution. The paper also outlines the Canada-United States Air Quality Agreement and the effect of the acid rain provisions on deposition in Canada. Finally, it considers the future work that must be undertaken to further resolve the acid rain problem. 8 refs., 5 figs., 1 tab

Full Text Available Endemic tuberculosis (TB was almost certainly present in Canadian aboriginal people (aboriginal Canadians denotes status Indians, Inuit, nonstatus Indians and metis as reported by Statistics Canada before the Old World traders arrived. However, the social changes that resulted from contact with these traders created the conditions that converted endemic TB into epidemic TB. The incidence of TB varied inversely with the time interval from this cultural collision, which began on the east coast in the 16th century and ended in the Northern Territories in the 20th century. This relatively recent epidemic explains why the disease is more frequent in aboriginal children than in Canadian-born nonaboriginal people. Treatment plans must account for the socioeconomic conditions and cultural characteristics of the aboriginal people, especially healing models and language. Prevention includes bacillus Calmette-Guerin vaccination and chemoprophylaxis, and must account for community conditions, such as rates of suicide, which have exceeded the rate of TB. The control of TB requires a centralized program with specifically directed funding. It must include a program that works in partnership with aboriginal communities.

The biomolecular era is rapidly becoming shaped around the supreme interest in targeted therapy for patients with non-small cell lung cancer. Tissue analysis has become crucial in the definition of biomarkers and genomic signatures able to predict the response to treatment or even survival. Lung screening programs and minimally invasive thoracic surgery are jointly aimed at increasing the quantity and quality of specimens of non-small cell lung cancer caught at the earliest stages with the attendant, significant, effect on patient survival. In addition, biomolecular researchers are disclosing an ever-increasing cohort of patients with specific genetic mutations that make their cancer susceptible to individualized treatment. When needed for immunohistochemical characterization, investigators are ready to request "research biopsies" to consolidate tissue availability for clinical trials, translational research, and in biobanks. With unique and diverse tools in the surgical armamentarium, the thoracic surgeon plays a central role in this new multidisciplinary professional environment, actively participating in creating the foundations of the biomolecular era.

Nanotechnology is an emerging discipline, having power to revolutionarize every scientific field to a very deep level which previously thought to be a science fiction. Having a great potential to beneficially change the way a disease is diagnosed, treated and prevented, nanotechnology practically impacts on state of the art healthcare technologies and plays a crucial role in changing the field of surgery. Surgeons are constantly looking for minimally invasive ways to treat their patients, as recovery is faster when a lesser trauma is inflicted upon a patient, scarring is lessened and there are usually fewer complications in the aftermath of the operation. Through nanotechnology, tiny biosensors could be constructed which could take these factors into account, thus shortening the patient recovery period and saving hospitals money, reducing infection rates within the hospital, reducing the waiting lists for operation and allowing doctors to treat more patients in the same period of time. This review employs a thematic analysis of online series of academic papers focuses on the potentials of nanotechnology in surgery, especially in plastic surgery and addresses the possible future prospects of nanotechnology in this field.

Since 1901 Nobel Prize is awarded for exceptional achievements in physics, chemistry, literature, peace, economy (since 1968) and medicine or physiology. The first aim of the paper is to provide an overview of surgeons - winners of Nobel Prize for medicine or physiology. Although the prominent neurosurgeons were frequently nominated as Nobel Prize candidates, surprisingly no neurosurgeon received this prestigious award so far despite that the results of their research transgressed the relatively narrow limits of neurosurgical speciality.The most prominent leaders in the field of neurosurgery, such as Victor Horsley, Otfrid Foerster, Walter Dandy and Harvey Cushing are discussed from the point of their nominations. The overview of the activity of the Portuguese neurologists and Nobel Prize Winter in 1949 Egas Moniz (occasionally erroneously reported as neurosurgeon) is also provided. Although his work on brain angiography has fundamentally changed the diagnostic possibilities in neurology and neurosurgery, he was eventually awarded Nobel Prize for the introduction of the currently outdated frontal lobotomy.The fact that none of the above mentioned prominent neurosurgeons has not been recognised by Nobel Prize, may be attributed to the fact that their extensive work cannot be captured in a short summary pinpointing its groundbreaking character.

BACKGROUND: Climate change models predict increasing frequency of extreme weather. One of the challenges hospitals face is how to make sure they have adequate staffing at various times of the year. AIMS: The aim of this study was to examine the effect of this severe inclement weather on hospital admissions, operative workload and cost in the Irish setting. We hypothesised that there is a direct relationship between cold weather and workload in a regional orthopaedic trauma unit. METHODS: Trauma orthopaedic workload in a regional trauma unit was examined over 2 months between December 2009 and January 2010. This corresponded with a period of severe inclement weather. RESULTS: We identified a direct correlation between the drop in temperature and increase in workload, with a corresponding increase in demand on resources. CONCLUSIONS: Significant cost savings could be made if these injuries were prevented. While the information contained in this study is important in the context of resource planning and staffing of hospital trauma units, it also highlights the vulnerability of the Irish population to wintery weather.

Biodegradable polymers, especially those belonging to the family of polylactic acid (PLA) and polyglycolic acid (PGA), play an increasingly important role in orthopaedics. These polymers degrade by hydrolysis and enzymatic activity and have a range of mechanical and physical properties that can be engineered appropriately to suit a particular application. Their degradation characteristics depend on several parameters including their molecular structure, crystallinity, and copolymer ratio. These biomaterials are also rapidly gaining recognition in the fledging field of tissue engineering because they can be fashioned into porous scaffolds or carriers of cells, extracellular matrix components, and bioactive agents. Although their future appears to be bright, several questions regarding the biocompatibility of these materials linger and should be addressed before their wide-scale use. In the context of musculoskeletal tissue, this report provides a comprehensive review of properties and applications of biodegradable PLA/PGA polymers and their copolymers. Of special interest are orthopaedic applications, biocompatibility studies, and issues of sterilization and storage of these versatile biomaterials. Also discussed is the fact that terms such as PLA, PGA, or PLA-PGA do not denote one material, but rather a large family of materials that have a wide range of differing bioengineering properties and concomitant biological responses. An analysis of some misconceptions, problems, and potential solutions is also provided. PMID:9788368

Some details of this program are discussed, including the philosophy and development of CANDU safeguards systems; the unique equipment developed for these systems; the provision of technical experts; training programs; liaison with other technical organizations; research and development; implementation of safeguards systems at various nuclear facilities; and the anticipated future direction of the safeguards program
Canada is a multicultural country which was mainly established by immigrants. Just because of that, Canadian govern⁃ment has carried out the policy of multiculturalism since1970s. However, it has encountered many problems such as policy con⁃flicts, national identity, democracy-inquiry and racial discrimination, etc. Hence the Canadian multiculturalism has been in a di⁃lemma.
The O-arm system has recently been introduced and has the capability of combined two-dimensional (2-D) fluoroscopy imaging and three-dimensional computed tomography imaging. In this study, an orthopaedic surgical procedure using C-arm and O-arm systems in their 2-D fluoroscopy modes was simulated and the radiation doses to susceptible organs to which operators can be exposed were investigated. The experiments were performed in four configurations of the location of the X-ray source and detector. Shielding effects on the thyroid surface and the direct exposure delivered to the surgeon's hands were also compared. The results obtained show that the O-arm delivered higher doses to the sensitive organs of the operator in all configurations. The thyroid shield cut-off 89 % of the dose in the postero-anterior configuration of both imaging systems. Thus, the operators need to pay more attention to managing radiation exposure, especially when using the O-arm system. (authors)

Full Text Available Abstract Background Total joint replacement (TJR of the hip or knee for osteoarthritis is among the most common elective surgical procedures. There is some inequity in provision of TJR. How decisions are made about who will have surgery may contribute to disparities in provision. The model of shared decision-making between patients and clinicians is advocated as an ideal by national bodies and guidelines. However, we do not know what happens within orthopaedic practice and whether this reflects the shared model. Our study examined how decisions are made about TJR in orthopaedic consultations. Methods The study used a qualitative research design comprising semi-structured interviews and observations. Participants were recruited from three hospital sites and provided their time free of charge. Seven clinicians involved in decision-making about TJR were approached to take part in the study, and six agreed to do so. Seventy-seven patients due to see these clinicians about TJR were approached to take part and 26 agreed to do so. The patients' outpatient appointments ('consultations' were observed and audio-recorded. Subsequent interviews with patients and clinicians examined decisions that were made at the appointments. Data were analysed using thematic analysis. Results Clinical and lifestyle factors were central components of the decision-making process. In addition, the roles that patients assigned to clinicians were key, as were communication styles. Patients saw clinicians as occupying expert roles and they deferred to clinicians' expertise. There was evidence that patients modified their behaviour within consultations to complement that of clinicians. Clinicians acknowledged the complexity of decision-making and provided descriptions of their own decision-making and communication styles. Patients and clinicians were aware of the use of clinical and lifestyle factors in decision-making and agreed in their description of clinicians' styles

A study was conducted in 4 Canadian processing plants in 1995-96 to determine the prevalence of quality defects in Canadian cattle. One percent of the annual number of cattle processed in Canada were evaluated on the processing floor and 0.1% were graded in the cooler. Brands were observed on 37% and multiple brands on 6% of the cattle. Forty percent of the cattle had horns, 20% of which were scurs, 33% were stubs, 10% were tipped, and 37% were full length. Tag (mud and manure on the hide) was observed on 34% of the cattle. Bruises were found on 78% of the carcasses, 81% of which were minor in severity. Fifteen percent of the bruises were located on the round, 29% on the loin, 40% on the rib, 16% on the chuck, and 0.02% on the brisket. Grubs were observed in 0.02% of the steers, and injection sites were observed in 1.3% of whole hanging carcasses. Seventy percent of the livers were passed for human food and 14% for pet food; 16% were condemned. Approximately 71% of the liver condemnations were due to liver abscesses. Four percent of the heads, 6% of the tongues, and 0.2% of whole carcasses were condemned. The pregnancy rate in female cattle was approximately 6.7%. The average hot carcass weight was 357 kg (s = 40) in steers, 325 kg (s = 41) in heifers, 305 kg (s = 53) in cows, 388 kg (s = 62) in virgin bulls and 340 kg (s = 39) in mature bulls. The average ribeye area in all cattle was 84 cm2 (s = 12); range 29 cm2 to 128 cm2. Grade fat was highly variable and averaged 9 mm (s = 4) for steers and heifers, 6 mm (s = 6) for cows, 5 mm (s = 1) for virgin bulls, and 4 mm (s = 0.5) for mature bulls. The average lean meat yield was 59.7% in cattle (s = 3.4); range 39% to 67%. One percent of the carcasses were devoid of marbling, 1% were dark cutters, and 0.05% of the steer carcasses were staggy. Six percent of the carcasses had poor conformation, 3.7% were underfinished, and 0.7% were overfinished. Yellow fat was observed in 4% of the carcasses; 10% of carcasses were

Full Text Available Background The importance of cross-border healthcare, medical and health tourism plays a significant role in the European health policy and health management. After dentistry, orthopaedic treatments are the leading motivation for seeking care in Hungary, as patients with rheumatic and motion diseases are drawn to the thermal spas and well-established orthopaedic centres. This paper aims to gain insight into foreign patients’ perspectives on their experience of having sought medical tourism in orthopaedic care in Hungary. Methods A patient survey was conducted in 2012 on motivations for seeking treatment abroad, orthopaedic care received and overall satisfaction. In addition, health professionals’ interviews, and 17 phone interviews were conducted in 2013 with Romanian patients who had orthopaedic treatment in Hungary. Finally, medical records of foreign patients were analysed. Results The survey was completed by 115 participants – 61.1% females, mean age= 41.9, 87% Romanian origin. Most of the patients came to Hungary for orthopaedic surgeries, e.g. arthroscopy, knee/hip prosthesis or spinal surgery. 72.6% chose Hungary because of related to perceived better quality and longstanding culture of Hungarian orthopaedic care. Over 57% of patients reported being ‘very satisfied’ with care received and 41.6% ‘satisfied’. The follow-up interviews further reflected this level of satisfaction, therefore many respondents stating they have already recommended the Hungarian healthcare to others. Conclusion Based on the findings, patients from neighbouring regions are increasingly seeking orthopaedic care in Hungary. Patients having orthopaedic care are highly satisfied with the quality of care, the whole treatment process from the availability of information to discharge summaries and would consider returning for further treatments.
Full Text Available Physicians' emotions affect both patient care and personal well-being. Surgeons appear at particularly high risk, as evidenced by the high rate of burnout and the alarming consequences in both their personal lives and professional behavior. The aim of this qualitative study is to explore the emotional experiences of surgeons and their impact on their surgical practice.27 purposively selected liver and pancreatic surgeons from 10 teaching hospitals (23 men, 4 women participated. Inclusion took place until data saturation was reached. Data were collected through individual interviews and thematically analyzed independently by 3 researchers (a psychologist, a psychiatrist, and a surgeon. 7 themes emerged from the analysis, categorized in 3 main or superordinate themes, which described surgeons' emotional experience before, during, and after surgery. Burdensome emotions are present throughout all 3 periods (and invade life outside the hospital-surgeons' own emotions, their perception of patients' emotions, and their entwinement. The interviewees described the range of emotional situations they face (with patients, families, colleagues, the influence of the institutional framework (time pressure and fatigue, cultural pressure to satisfy the ideal image of a surgeon, as well as the emotions they feel (including especially anxiety, fear, distress, guilt, and accountability.Emotions are ubiquitous in surgeons' experience, and their exposure to stress is chronic rather than acute. Considering emotions only in terms of their relations to operative errors (as previous studies have done is limiting. Although complications are quite rare events, the concern for possible complications is an oppressive experience, regardless of whether or not they actually occur.
