    Kocher, Mininder S

    2015-01-01

    Value has become the buzzword of contemporaneous health care reform. Value is defined as outcomes relative to costs. Orthopaedic surgery has come under increasing scrutiny due to high procedural costs. However, orthopaedic surgery may actually be a great value given the benefits of treatment. The American Academy of Orthopaedic Surgeons (AAOS) Value Project team was tasked to develop a model for assessing the benefits of orthopaedic surgery including indirect costs related to productivity and health-related quality of life. This model was applied to 5 orthopaedic conditions demonstrating robust societal and economic value. In all cost-effectiveness models, younger patients demonstrated greater cost-effectiveness given increased lifespan and productivity. This has tremendous implications within the field of pediatric orthopedic surgery. Pediatric orthopaedics may be the best value in medicine!

  4. Prophylactic antibiotics in orthopaedic surgery.

    Prokuski, Laura; Clyburn, Terry A; Evans, Richard P; Moucha, Calin S

    2011-01-01

    The use of prophylactic antibiotics in orthopaedic surgery has been proven effective in reducing surgical site infections after hip and knee arthroplasty, spine procedures, and open reduction and internal fixation of fractures. To maximize the beneficial effect of prophylactic antibiotics, while minimizing any adverse effects, the correct antimicrobial agent must be selected, the drug must be administered just before incision, and the duration of administration should not exceed 24 hours.

    To evaluate the effectiveness of intravenous iron treatment, with or without associated erythropoietin (rHuEPO), measured as haemoglobin (Hb) increase. The relationships between the Hb increase and parameters used to evaluate anaemia were analysed. Retrospective observational study carried out in two third-level hospitals between January 2005 and December 2009. The study included patients with iron deficiency anaemia scheduled for elective orthopaedic surgery and treated with intravenous iron sucrose alone or associated with rHuEPO. Treatment efficacy was analysed based on the Hb increase from baseline to just before surgery. A total of 412 patients who received a median of 800mg of iron sucrose were included; 125 of them (30.4%) additionally received 2.4 vials of rHuEPO. The Hb increase was 0.8 (1.1) g/dL in patients treated with intravenous iron and 1.5 (1.3) g/dL in those additionally given rHuEPO(P<.01). The percentage of hypochromic red blood cells (r=0.52) and soluble transferrin receptor (r=0.59) value were significantly correlated to the Hb increase in patients receiving iron. In patients with iron deficiency anaemia, the effectiveness of iron sucrose treatment to optimize Hb before surgery was moderate; adjuvant administration of erythropoietin improved the results. Determination of functional iron status parameters may improve the treatment effectiveness. Copyright © 2014 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

    Cross, Michael Brian; Yi, Paul Hyunsoo; Thomas, Charlotte F; Garcia, Jane; Della Valle, Craig J

    2014-03-01

    Malnutrition can increase the risk of surgical site infection in both elective spine surgery and total joint arthroplasty. Obesity and diabetes are common comorbid conditions in patients who are malnourished. Despite the relatively high incidence of nutritional disorders among patients undergoing elective orthopaedic surgery, the evaluation and management of malnutrition is not generally well understood by practicing orthopaedic surgeons. Serologic parameters such as total lymphocyte count, albumin level, prealbumin level, and transferrin level have all been used as markers for nutrition status. In addition, anthropometric measurements, such as calf and arm muscle circumference or triceps skinfold, and standardized scoring systems, such as the Rainey-MacDonald nutritional index, the Mini Nutritional Assessment, and institution-specific nutritional scoring tools, are useful to define malnutrition. Preoperative nutrition assessment and optimization of nutritional parameters, including tight glucose control, normalization of serum albumin, and safe weight loss, may reduce the risk of perioperative complications, including infection.

    Rangan, A; Jefferson, L; Baker, P; Cook, L

    2014-05-01

    The aim of this study was to review the role of clinical trial networks in orthopaedic surgery. A total of two electronic databases (MEDLINE and EMBASE) were searched from inception to September 2013 with no language restrictions. Articles related to randomised controlled trials (RCTs), research networks and orthopaedic research, were identified and reviewed. The usefulness of trainee-led research collaborations is reported and our knowledge of current clinical trial infrastructure further supplements the review. Searching yielded 818 titles and abstracts, of which 12 were suitable for this review. Results are summarised and presented narratively under the following headings: 1) identifying clinically relevant research questions; 2) education and training; 3) conduct of multicentre RCTs and 4) dissemination and adoption of trial results. This review confirms growing international awareness of the important role research networks play in supporting trials in orthopaedic surgery. Multidisciplinary collaboration and adequate investment in trial infrastructure are crucial for successful delivery of RCTs.

  13. Venturing into the overlap between pediatric orthopaedics and hand surgery.

    Science.gov (United States)

    Kozin, Scott H; Zlotolow, Dan A; Ratner, Joshua A

    2014-01-01

    There is an overlap between pediatric orthopaedic surgery and hand surgery. A pediatric orthopaedic surgeon is accustomed to the intricacies of the immature skeleton, whereas a hand surgeon is more familiar with the regional anatomy and finer surgical techniques. Many hand diagnoses and surgical techniques are appropriate for the pediatric orthopaedic surgeon, including straightforward duplicated thumb reconstruction of a trigger thumb. Many pediatric diagnoses are more suitable for treatment by a hand surgeon, including simple syndactyly release and complex duplicated thumb reconstruction. Other procedures, such as pollicization, cleft hand reconstruction, synpolydactyly release, and macrodactyly management, require more advanced expertise for successful treatment. It is helpful for pediatric orthopaedic surgeons and hand surgeons to be familiar with the indications, surgical techniques, outcomes, and complications of pediatric hand surgery.

  14. The Current Role of Stem Cells in Orthopaedic Surgery

    Directory of Open Access Journals (Sweden)

    Maniar HH

    2015-11-01

    Full Text Available Basic science and experimental research on stem cells has increased exponentially in the last decade. Our present knowledge about stem cell biology is better than ever before. This new paradigm shift in research has been reflected in the field of orthopaedic surgery. Various experimental models have suggested a potential application of stem cells for different orthopaedic conditions, and early clinical results of stem cell use have been encouraging. These cells can be easily isolated, processed and made available for clinical use. From healing of bone defects caused by trauma, tumor or infection to cartilage defects, nerve, tendon and ligament healing, stem cell use has the potential to revolutionize orthopaedic practice. The purpose of this article is to orient a general orthopaedic surgeon towards the current use and clinical applications of stem cell based therapy in orthopaedics and to provide a complete overview of the clinical advances in this field.

  15. [The history and development of computer assisted orthopaedic surgery].

    Science.gov (United States)

    Jenny, J-Y

    2006-10-01

    Computer assisted orthopaedic surgery (CAOS) was developed to improve the accuracy of surgical procedures. It has improved dramatically over the last years, being transformed from an experimental, laboratory procedure into a routine procedure theoretically available to every orthopaedic surgeon. The first field of application of computer assistance was neurosurgery. After the application of computer guided spinal surgery, the navigation of total hip and knee joints became available. Currently, several applications for computer assisted surgery are available. At the beginning of navigation, a preoperative CT-scan or several fluoroscopic images were necessary. The imageless systems allow the surgeon to digitize patient anatomy at the beginning of surgery without any preoperative imaging. The future of CAOS remains unknown, but there is no doubt that its importance will grow in the next 10 years, and that this technology will probably modify the conventional practice of orthopaedic surgery.

  20. National Institutes of Health Funding to Departments of Orthopaedic Surgery at U.S. Medical Schools.

    Science.gov (United States)

    Silvestre, Jason; Ahn, Jaimo; Levin, L Scott

    2017-01-18

    The National Institutes of Health (NIH) is the largest supporter of biomedical research in the U.S., yet its contribution to orthopaedic research is poorly understood. In this study, we analyzed the portfolio of NIH funding to departments of orthopaedic surgery at U.S. medical schools. The NIH RePORT (Research Portfolio Online Reporting Tools) database was queried for NIH grants awarded to departments of orthopaedic surgery in 2014. Funding totals were determined for award mechanisms and NIH institutes. Trends in NIH funding were determined for 2005 to 2014 and compared with total NIH extramural research funding. Funding awarded to orthopaedic surgery departments was compared with that awarded to departments of other surgical specialties in 2014. Characteristics of NIH-funded principal investigators were obtained from department web sites. In 2014, 183 grants were awarded to 132 investigators at 44 departments of orthopaedic surgery. From 2005 to 2014, NIH funding increased 24.3%, to $54,608,264 (p = 0.030), but the rates of increase seen did not differ significantly from those of NIH extramural research funding as a whole (p = 0.141). Most (72.6%) of the NIH funding was awarded through the R01 mechanism, with a median annual award of $343,980 (interquartile range [IQR], $38,372). The majority (51.1%) of the total funds supported basic science research, followed by translational (33.0%), clinical (10.0%), and educational (5.9%) research. NIH-funded orthopaedic principal investigators were predominately scientists whose degree was a PhD (71.1%) and who were male (79.5%). Eleven NIH institutes were represented, with the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) providing the preponderance (74.2%) of the funding. In 2014, orthopaedic surgery ranked below the surgical departments of general surgery, ophthalmology, obstetrics and gynecology, otolaryngology, and urology in terms of NIH funding received. The percentage increase of NIH

    Factors associated with successful selection in U.S. Army orthopaedic surgical programs are unreported. The current analysis includes survey data from all Army orthopaedic surgery residency program directors (PDs) to determine these factors. PDs at all Army orthopaedic surgery residency programs were provided 17 factors historically considered critical to successful selection and asked to rank order the factors as well as assign a level of importance to each. Results were collated and overall mean rankings are provided. PDs unanimously expressed that performance during the on-site orthopaedic surgery rotation at the individual program director's institution was most important. Respondents overwhelmingly reported that Steps 1 and 2 licensing exam scores were next most important, respectively. Survey data demonstrated that little importance was placed on letters of recommendation and personal statements. PDs made no discriminations based on allopathic or osteopathic degrees. The most important factors for Army orthopaedic surgery residency selection were clerkship performance at the individual PD's institution and licensing examination score performance. Army PDs consider both USMLE and COMLEX results, because Army programs have a higher percentage of successful osteopathic applicants.

    Cvetanovich, Gregory L; Chalmers, Peter N; Bach, Bernard R

    2015-08-05

    Industry financial relationships for orthopaedic surgeons in the United States are now publicly reported in the Sunshine Act Open Payments database. We sought to present these data in a more easily understandable format and to describe how industry relationships in orthopaedic surgery compare with other surgical subspecialties. The Open Payments database was searched for all records of industry financial relationships for orthopaedic surgeons. Data analyzed included the value of reported financial relationships per surgeon, the type of financial relationship, and geographic region. Similar analytics were collected for neurological surgery, urology, plastic surgery, and otolaryngology. Data were normalized to the overall number of providers in each subspecialty in the United States from the American Medical Association 2012 data. For 12,320 orthopaedic surgeons, 58,127 industry financial relationships were reported, with a total value of $80.2 million. Royalties or licensing fees, which were received by 1.7% of U.S. orthopaedic surgeons, accounted for 69.5% of the total monetary value of payments to orthopaedic surgeons. Between August and December 2013, 50.1% of U.S. orthopaedic surgeons had a reported financial relationship. Orthopaedics had the second lowest percentage of physicians with industry financial relationships among the five surgical subspecialties studied. The overall value of payments per orthopaedic surgeon was higher than in the other subspecialties, driven by the large value of royalties and licensing. One-half of U.S. orthopaedic surgeons have industry financial relationships reported in the Open Payments database. Orthopaedic surgeons are less likely than most surgical subspecialists to receive industry payments, and the majority of the overall value of orthopaedic financial relationships is driven by a small number of orthopaedic surgeons receiving royalties and licensing for reimbursable innovation within the field.

    2015-03-01

    The use of robots in orthopaedic surgery is an emerging field that is gaining momentum. It has the potential for significant improvements in surgical planning, accuracy of component implantation and patient safety. Advocates of robot-assisted systems describe better patient outcomes through improved pre-operative planning and enhanced execution of surgery. However, costs, limited availability, a lack of evidence regarding the efficiency and safety of such systems and an absence of long-term high-impact studies have restricted the widespread implementation of these systems. We have reviewed the literature on the efficacy, safety and current understanding of the use of robotics in orthopaedics.

    99m Tc-labeled heparin test was performed for early detection of phlebitis or pulmonary embolism after orthopaedic prothesis. Heparinic treatment and surgery per se were demonstrated to have no effect on the results. If this test demonstrates a statistical difference for pathologic patients, it is of greater value to consider ratio between rates before and after intervention.

  9. The use of arthrography in pediatric orthopaedic surgery.

    Science.gov (United States)

    Nowicki, Philip D; Duhn, Ryan

    2014-08-01

    Surgery near pediatric joints can be challenging because it is difficult to visualize vital articular structures. Assessment of underlying pathology is also challenging because the joint structures have not yet ossified. Arthrography is a useful tool that is quick and minimally invasive and allows adequate visualization of joint anatomy during surgery, which aids intraoperative decision making. In pediatric patients, arthrography is most useful for visualization of the elbow, knee, and hip joints. This tool can help the surgeon to refine the diagnosis and management of pediatric fractures and aids in surgical assessment during joint and limb reconstruction. Arthrography adds minimal time to surgery and carries a low risk of complications; it should be part of the armamentarium of any surgeon who treats pediatric orthopaedic patients.

  16. Surgical hand scrub practices in orthopaedic surgery.

    Science.gov (United States)

    Khan, Adnan; McLaren, Sandra G; Nelson, Carl L

    2003-09-01

    The purpose of this study was to determine whether the practice of surgical hand scrubbing among orthopaedic surgeons, faculty, residents, and nurses met the institution's recommended 5-minute scrub policy and how often a 2-minute surgical hand scrub was used. Forty-eight subjects' hand scrub times were recorded discreetly for a total of 125 observations. All individuals scrubbed for a mean of 2.54 minutes and all scrubbed less than the 5-minute institutionally recommended policy. We found that 35.2% scrubbed less than 2 minutes and 64.8% scrubbed greater than 2 minutes. The subjects studied were polled to determine whether they knew the scrub policy, the minimum effective scrub time, and their perception of how long they scrub. Three of the 16 respondents correctly answered the question regarding the hospital's recommended policy regarding scrub time of 5 minutes. All stated they thought they scrubbed at least 2 minutes and all agreed that at least a 2-minute scrub should be done.

    2016-12-01

    Background: Since the combination of orthopaedic and traumatology surgery as a single speciality, an extremely wide variety of orthopaedic and trauma surgery centres have been founded in Germany. The present investigation analysed the degree to which additional value has been generated by merging two previously independent university departments - one for orthopaedics, the other for trauma surgery - into a single orthopaedics and trauma surgery centre. Material and Methods: The centre, merged in 1 June 2013, is led by two equal co-chairs (a full professor for orthopaedics and a full professor for trauma surgery). It consists of an acute division and five other divisions for specific parts of the body. The pre-existing certifications (level 1 trauma- and joint arthroplasty centre) were maintained in the new merged entity. Data from patient and employee questionnaires, as well as key economic indicators, were compared before and after the merger. Results: 11 % of the patients rated the medical treatment as mediocre or bad before the merger. After the merger, 5.7 % of the patients were moderately satisfied or unsatisfied; 92 % would recommend the merged centre to others and would return for further treatment. The evaluation of patient complaints before and after the merger showed no change. The evaluation of the employee questionnaires showed heterogeneous results. Overall, positive evaluations predominated, but in areas where there had been major changes, negative aspects were occasionally reported. The merger did not bring about any essential change in the number of in-patients (2012: 6693; 2014: 6649) or in the severity of the medical cases (CMI in 2012: 1.41; in 2014: 1.45). But in 2015, there was an increase in the number of in-patients (6837) and in the CMI (1.54). In the out-patient clinic, the merger led to a reduction in the material costs per patient (2012: 3.53 €/patient; 2014: 3.07 €/patient) and in the staff costs. The material costs for the

  19. Understanding how orthopaedic surgery practices generate value for healthcare systems.

    Science.gov (United States)

    Olson, Steven A; Mather, Richard C

    2013-06-01

    Orthopaedic surgery practices can provide substantial value to healthcare systems. Increasingly, healthcare administrators are speaking of the need for alignment between physicians and healthcare systems. However, physicians often do not understand what healthcare administrators value and therefore have difficulty articulating the value they create in discussions with their hospital or healthcare organization. Many health systems and hospitals use service lines as an organizational structure to track the relevant data and manage the resources associated with a particular type of care, such as musculoskeletal care. Understanding service lines and their management can be useful for orthopaedic surgeons interested in interacting with their hospital systems. We provide an overview of two basic types of value orthopaedic surgeons create for healthcare systems: financial or volume-driven benefits and nonfinancial quality or value-driven patient care benefits. We performed a search of PubMed from 1965 to 2012 using the term "service line." Of the 351 citations identified, 18 citations specifically involved the use of service lines to improve patient care in both nursing and medical journals. A service line is a structure used in healthcare organizations to enable management of a subset of activities or resources in a focused area of patient care delivery. There is not a consistent definition of what resources are managed within a service line from hospital to hospital. Physicians can positively impact patient care through engaging in service line management. There is increasing pressure for healthcare systems and hospitals to partner with orthopaedic surgeons. The peer-reviewed literature demonstrates there are limited resources for physicians to understand the value they create when attempting to negotiate with their hospital or healthcare organization. To effectively negotiate for resources to provide the best care for patients, orthopaedic surgeons need to claim and

    2016-01-01

    An anaemia clinic was established to improve the preoperative management of elective orthopaedic patients scheduled for arthroplasty. This paper is a report on the first 100 patients assessed. To assess the incidence and causes of anaemia in patients on a waiting list for elective arthroplasty in a public hospital and to assess the impact of anaemia detection in this patient population. Patients attending an Anaemia Clinic for elective orthopaedic surgical patients, during March 2010 to June 2013 were studied. Outcome measures included change in haemoglobin preoperative results and perioperative transfusion rates by preoperative haemoglobin. Seventeen per cent of patients scheduled for elective surgery were found to be anaemic. Of the 100 patients who attended, approximately half were found to be iron deficient and the remainder had anaemia of chronic disease. Serum ferritin anaemia were able to be treated, in all cases, to achieve a significant increase in preoperative haemoglobin. The general unavailability of erythropoietin limited effective intervention for the non-iron-deficient anaemic patients. Seven patients had their surgery cancelled because of the screening programme. Half of the anaemic patients in a joint replacement screening clinic were iron deficient, and treatment was effective in improving the pre-operative haemoglobin and reducing perioperative transfusion rates. This screening process should improve patient outcome. Another important finding in this group of patients is that ferritin levels cannot be reliably used as the sole indicator in the diagnosis of iron deficiency anaemia in this group of patients undergoing elective arthroplasty. © 2015 Royal Australasian College of Physicians.

  2. Pudendal nerve palsy in trauma and elective orthopaedic surgery.

    Science.gov (United States)

    Polyzois, Ioannis; Tsitskaris, Konstantinos; Oussedik, Sam

    2013-12-01

    The incidence of pudendal nerve palsy following routine trauma and elective orthopaedic surgery procedures ranges from 1.9% to 27.6%. Excessive and/or prolonged traction against the perineal post of a traction table, leading to direct compression and localised ischaemia to the nerve are suggested mechanisms of injury. Misuse of traction and the inappropriate placement of the perineal post, leading to crushing and stretching of the pudendal nerve, are two main contributing factors leading to its postoperative palsy. The sequelae may be sensory, motor or mixed. In most cases, these injuries are transient and tend to resolve within several weeks or months. However, complete neurological recovery may be unpredictable and the effects of ongoing dysfunction potentially disastrous for the individual. In terms of preventative measures, magnitude and duration of traction time should be minimised; traction should be limited to the critical operative steps only. Additionally, the perineal post should be placed between the genitalia and the contralateral leg. A well-padded, large-diameter perineal post should be used (>10cm). Adequate muscle relaxation during anaesthesia is particularly important in young men who have strong muscles and thus require larger traction forces when compared to elderly patients. Orthopaedic surgeons should be aware of the pathophysiology behind the development of this palsy and the measures that can be employed to reduce its occurrence. In procedures where a traction table is employed, consenting for pudendal nerve palsy should be considered by the surgical team.

    Recent studies have linked the use of regional anaesthesia to improved outcomes. Epidemiological research on utilization, trends, and disparities in this field is sparse; however, large nationally representative database constructs containing anaesthesia-related data, demographic information, and multiyear files are now available. Together with advances in research methodology and technology, these databases provide the foundation for epidemiological research in anaesthesia. We present an overview of selected studies that provide epidemiological data and describe current anaesthetic practice, trends, and disparities in orthopaedic surgery in particular. This literature suggests that that even among orthopaedic surgical procedures, which are highly amenable to regional anaesthetic techniques, neuraxial anaesthetics and peripheral nerve blocks are used in only a minority of procedures. Trend analyses show that peripheral nerve blocks are gaining in popularity, whereas use of neuraxial anaesthetics is remaining relatively unchanged or even declining over time. Finally, significant disparities and variability in anaesthetic care seem to exist based on demographic and health-care-related factors. With anaesthesia playing an increasingly important part in population-based health-care delivery and evidence indicating improved outcome with use of regional anaesthesia, more research in this area is needed. Furthermore, prevalent disparities and variabilities in anaesthesia practice need to be specified further and addressed in the future.

    @@ The principle of navigation surgery was first adopted in neurosurgery where a mechanical rigid frame was used in the stereotactic surgery to locate a deep ganglia and tract in the brain by Clark and Horsley1 in 1906. The planning was based on anatomical atlas of the brain and was not patient specific. The navigation procedure was possible with a rigid mechanical frame to define the trajectory with a rigid instrument holder on a rigid fixation of the operating structure, i.e. the skull. With the advancements in 3-D medical imaging, i.e. CT in 1971,MR imaging in 1973, general stereotaxis was possible and became specific to anatomy of each individual patient.Together with the advancement of computer technology:VAX in 1976, Apple in 1977, IBM personal computer in 1981, computer assisted stereotaxis was possible and in 1985, the term computer assisted surgery (CAS) was proposed by Sohn and Robins.2 With further development of 3-D tracking by NDI with Optotrak 1990, computer assisted orthopaedic surgery (CAOS) developed and gradually became widely applicable in clinical practice.

    Perioperative vision loss is a rare complication of orthopaedic surgery and has been documented after spine, knee, hip, and shoulder procedures. It is associated with several ophthalmologic diagnoses, most commonly ischemic optic neuropathy. Although the pathophysiology remains unclear, current evidence suggests that systemic hemodynamic compromise and altered balance of intraocular perfusion contribute to the development of ischemic optic neuropathy. Although vision recovery has been reported, the prognosis of perioperative vision loss is poor, and no proven effective treatment is available. Perioperative vision loss is unpredictable and can occur in healthy patients. Associated risk factors include pediatric or elderly age, male sex, obesity, anemia, hypotension or hypertension, perioperative blood loss, prolonged surgical time, and prone positioning. Preventive strategies include avoiding direct pressure to the eye, elevating the head, optimizing perioperative hemodynamic status, and minimizing surgical time with staged surgical procedures as appropriate.

    Injuries are inherent to the sport of American football and often require operative management. Outcomes have been reported for certain surgical procedures in professional athletes in the National Football League (NFL), but there is little information comparing the career effect of these procedures. To catalog the postoperative outcomes of orthopaedic procedures in NFL athletes and to compare respective prognoses and effects on careers. Case series; Level of evidence, 4. Athletes in the NFL undergoing procedures for anterior cruciate ligament (ACL) tears, Achilles tendon tears, patellar tendon tears, cervical disc herniation, lumbar disc herniation, sports hernia, knee articular cartilage repair (microfracture technique), forearm fractures, tibial shaft fractures, and ankle fractures were identified through team injury reports or other public records. Game and performance statistics during the regular season were collected before and after surgery. Statistical analysis was performed with significance accepted as P NFL athletes were included. Overall, 79.4% of NFL athletes returned to play after an orthopaedic procedure. Forearm open reduction and internal fixation (ORIF), sports hernia repair, and tibia intramedullary nailing (IMN) led to significantly higher return-to-play (RTP) rates (90.2%-96.3%), while patellar tendon repair led to a significantly lower rate (50%) (P NFL careers, with patellar tendon repair faring worst with respect to the RTP rate, career length after surgery, games played, and performance at 1 year and 2 to 3 years after surgery. © 2016 The Author(s).

    Pediatric orthopaedic surgery owes its development to many pioneering individuals, and the studies that these individuals have undertaken form the basis for the clinical decisions made on the modern pediatric orthopaedic service. The aim of our study was to use citation analysis to identify the top 100 papers in pediatric orthopaedic surgery. Using the Thomson Reuters Web of Knowledge, we searched for citations of all papers relevant to pediatric orthopaedics. The number of citations, authorship, year of publication, journal of publication, and country and institution of origin were recorded for each paper. The most cited paper was found to be the classic paper from 1963 by Salter and Harris that introduced the now-eponymous classification system for physeal injuries in the skeletally immature patient. The second most cited was Salter's paper describing the widely used osteotomy for the treatment of developmental dysplasia of the hip, and the third most cited was Catterall's description of the natural history of Legg-Calvé-Perthes disease. Most papers originated in the U.S., and most were published in this journal. A number of authors including Salter, Ponseti, Graf, and Loder had more than one paper in the top-100 list. This paper's identification of the classic papers of pediatric orthopaedic surgery gives us a unique insight into the development of pediatric orthopaedic surgery in the twentieth and early twenty-first centuries and identifies those individuals who have contributed the most to the body of knowledge used to guide evidence-based clinical decision-making in pediatric orthopaedics today.

    Scoliosis surgery is one of the most difficult orthopedic surgery that have been committed today as the failure rate of orthopedic surgery for adult patients is 15%. Aside from the long duration of surgery, this surgical failure is caused by failure in biomedical instrumentation. Furthermore, this kind of failure is causing inefficiency of the surgery. With current known orthopedic surgery method, three surgeons are needed in a single orthopedic surgery. In fact, a single surgery can take up to 8 hours to be done, which increases the risk of surgical failure. Based on this problem, authors hope that our orthopedic jacks could solve the problem.

    The aim of this study was to assess retrospectively the efficacy and complication rate of hindlimb peripheral nerve blocks (PNBs) in cats. Clinical records of cats that received PNBs and underwent hindlimb orthopaedic surgery from February 2010 to October 2014 were examined. Type of PNB, type and dose of local anaesthetic used, end-expiratory fraction of isoflurane (FE'Iso) administered, additional intraoperative analgesia, incidence of hypotension, postoperative opioid requirement, postoperative contralateral limb paralysis and neurological complications at the 6 week re-examination were investigated. Eighty-nine records were retrieved but only 69 were analysed. Four combinations of PNBs were used: 34 lateral preiliac (LPI) approach to lumbar plexus (LP) associated with lumbar paravertebral approach to sciatic nerve (SN); 20 LPI-LP associated with the lateral approach to SN; three LPI-LP associated with gluteal approach to SN; 12 dorsal-paravertebral (DPV) approach to LP associated with lateral SN. Levobupivacaine was used for the majority of PNBs. The mean intraoperative FE'Iso was 1.15%; hypotension was documented in 55.1% of anaesthetics, while 31.8% of cats received fentanyl and/or ketamine intraoperatively. Postoperatively, 72.7% of cats received at least one dose of opioid, while five cats required further postoperative analgesia (ketamine constant rate infusion and/or gabapentin). No cats showed contralateral limb paralysis and neurological complications at the 6 week re-examination. No differences were found when comparing the different PNBs used. PNBs contributed to perioperative anaesthesia/analgesia in cats undergoing hindlimb orthopaedic surgery. However, the clinical relevance of intraoperative hypotension needs further investigation. © The Author(s) 2015.

    The practice of medicine is based on evidence from peer-reviewed literature. As can occur with author-related funding, the integrity of the process by which manuscripts are reviewed, edited, and approved for publication may be at risk due to financial conflict of interest. The purpose of our study was to assess potential financial conflict of interest among physician editorial board members of orthopaedic surgery journals. We identified the physician editorial board members of 15 orthopaedic surgery journals and searched the 2014 payments that were archived in the Centers for Medicare & Medicaid Services Open Payments system (mandated by the Physician Payments Sunshine Act). Total dollar values were calculated and tabulated in a multilevel fashion: nothing reported, >$0 and ≤$10,000, >$10,000, >$250,000, and >$950,000. We identified 908 physician editors of 15 orthopaedic surgery journals. Something of financial value was received by 78% (712 of 908) of these individuals. Rates of editorial board potential financial conflict of interest for individual journals ranged from 4% to 73% in the >$10,000 category. At the >$250,000 mark, rates ranged from 0% (2 journals) to 31%. When applying the >$950,000 criterion, physician potential conflict of interest ranged from 0% (5 journals) to 13%. Editor-related potential financial conflicts of interest exist in the orthopaedic surgery journals that we analyzed. These potential financial conflicts could possibly impact reviews.

    Lately, individualized nursing care and patient satisfaction are important and current issues being discussed. But there is not enough information for patients undergoing orthopaedic surgery. The aim of this study was to determine the individualized care perception and satisfaction in nursing care levels in orthopaedic surgery patients. This descriptive cross-sectional study was conducted with 156 patients who underwent orthopaedic surgery. Data were collected using the personal information form, the Individualized Care Scale, and the Newcastle Satisfaction With Nursing Scale. The Spearman correlation analysis and descriptive statistics were performed. The mean individualized care and satisfaction with nursing care scores were found to be close to the preset maximum value, and it was determined that an increase in the level of awareness about nursing interventions and the level of perceived individualized care caused an increase in satisfaction levels regarding nursing care. Nurses should recognize the importance of performing individualized care in order to increase the level of satisfaction with nursing care in orthopaedic surgery patients.

    Assessing orthopaedic surgery residency applicants is a complex process. One important applicant characteristic not commonly measured during the interview process is moral behavior, a key component of the guidelines of the Accreditation Council for Graduate Medical Education for professionalism competency. We sought to determine whether a relationship exists between the results of residency selection interviews, as measured by match rank order, and moral reasoning skills, as measured by the revised version of the Defining Issues Test (DIT-2). The DIT-2, a psychological tool that has been validated in assessing moral reasoning in >30,000 subjects, was administered to orthopaedic surgery residency candidates on a voluntary basis during their interview day. Data were collected annually from four applicant classes (2009 to 2012) at one institution. Each candidate was interviewed by an orthopaedic faculty team and was ranked comparatively with the other interviewing applicants. The five-part aggregate interview method for ranking applicants for the match list included a focused interview station presenting ethical dilemmas as one part of determining rank order. One hundred and twenty-four fourth-year medical students interviewing for orthopaedic surgery residency were assessed with the DIT-2. The results from the DIT-2 produced a postconventional score, which correlates with various levels of moral development. Each applicant's postconventional score was then compared with the patient's overall rank order. Applicants had highly variable moral reasoning skills, with no relationship to the final rank list. Despite a wide range of DIT-2 scores, the interview process did not differentiate applicants based on moral reasoning skills. It remains unclear whether the DIT-2 could (or should) be used as an additional data point to help stratify orthopaedic residency applicants and to predict their performance.

    A randomised controlled trial was used to evaluate elective ambulatory orthopaedic surgery patients' emotions during internet-based patient education or face-to-face education with a nurse. The internet-based patient education was designed for this study and patients used websites individually based on their needs. Patients in the control group participated individually in face-to-face patient education with a nurse in the ambulatory surgery unit. The theoretical basis for both types of education was the same. Ambulatory orthopaedic surgery patients scored their emotions rather low at intervals throughout the whole surgical process, though their scores also changed during the surgical process. Emotion scores did not decrease after patient education. No differences in patients' emotions were found to result from either of the two different patient education methods.

  3. Workers' compensation status: does it affect orthopaedic surgery outcomes? A meta-analysis.

    Directory of Open Access Journals (Sweden)

    Vinícius Ynoe de Moraes

    Full Text Available INTRODUCTION: Previous reviews have demonstrated that patient outcomes following orthopaedic surgery are strongly influenced by the presence of Workers' Compensation. However, the variability in the reviews' methodology may have inflated the estimated strength of this association. The main objective of this meta-analysis is to evaluate the influence of Workers' Compensation on the outcomes of orthopaedic surgical procedures. METHODS: We conducted a systematic search of the literature published in this area from 1992-2012, with no language restrictions. The following databases were used MEDLINE (Ovid, Embase (Ovid, CINAHL, Google Scholar, LILACS and Pubmed. We also hand-searched the reference sections of all selected papers. We included all prospective studies evaluating the effect of compensation status on outcomes in adult patients who had undergone surgery due to orthopaedic conditions or diseases. Outcomes of interest included disease specific, region specific and/or overall quality of life scales/questionnaires and surgeons' personal judgment of the results. We used an assessment tool to appraise the quality of all included studies. We used Review Manager to create forest plots to summarize study data and funnel plots for the assessment of publication bias. RESULTS: Twenty studies met our eligibility criteria. The overall risk ratio for experiencing an unsatisfactory result after orthopaedic surgery for patients with compensation compared to non-compensated patients is 2.08 (95% CI 1.54-2.82. A similar association was shown for continuous data extracted from the studies using assessment scales or questionnaires (Standard Mean Difference = -0.70 95% CI -0.97- -0.43. CONCLUSIONS: Among patients who undergo orthopaedic surgical procedures, those receiving Workers' Compensation experience a two-fold greater risk of a negative outcome. Our findings show a considerably lower estimate of risk compared to previous reviews that include retrospective

    The use of smartphones and their associated applications (apps) provides new opportunities for physicians, and specifically orthopaedic surgeons, to integrate technology into clinical practice. The purpose of this study was twofold: to review all apps specifically created for orthopaedic surgeons and to survey orthopaedic residents and surgeons in the United States to characterize the need for novel apps. The five most popular smartphone app stores were searched for orthopaedic-related apps: Blackberry, iPhone, Android, Palm, and Windows. An Internet survey was sent to ACGME-accredited orthopaedic surgery departments to assess the level of smartphone use, app use, and desire for orthopaedic-related apps. The database search revealed that iPhone and Android platforms had apps specifically created for orthopaedic surgery with a total of 61 and 13 apps, respectively. Among the apps reviewed, only one had greater than 100 reviews (mean, 27), and the majority of apps had very few reviews, including AAOS Now and AO Surgery Reference, apps published by the American Academy of Orthopaedic Surgeons and AO Foundation, respectively. The national survey revealed that 84% of respondents (n = 476) have a smartphone, the majority (55%) have an iPhone, and that 53% of people with smartphones already use apps in clinical practice. Ninety-six percent of respondents who use apps reported they would like more orthopaedic apps and would pay an average of nearly $30 for useful apps. The four most requested categories of apps were textbook/reference, techniques/guides, OITE/board review, and billing/coding. The use of smartphones and apps is prevalent among orthopaedic care providers in academic centers. However, few highly ranked apps specifically related to orthopaedic surgery are available, and the types of apps available do not appear to be the categories most desired by residents and surgeons.

    The specialist in orthopaedic and traumatological surgery, like any other doctor, is subject to the current legal provisions while exercising their profession. Mandatory training in the medical-legal aspects of health care is essential. Claims against doctors are a reality, and orthopaedic and traumatological surgery holds first place in terms of frequency of claims according to the data from the General Council of Official Colleges of Doctors of Catalonia. Professionals must be aware of the fundamental aspects of medical professional liability, as well as specific aspects, such as defensive medicine and clinical safety. The understanding of these medical-legal aspects in the routine clinical practice can help to pave the way towards a satisfactory and safe professional career. The aim of this review is to contribute to this training, for the benefit of professionals and patients. Copyright © 2015 SECOT. Published by Elsevier Espana. All rights reserved.

  8. Computer-assisted orthopaedic surgery and robotic surgery in total hip arthroplasty.

    2013-03-01

    Various systems of computer-assisted orthopaedic surgery (CAOS) in total hip arthroplasty (THA) were reviewed. The first clinically applied system was an active robotic system (ROBODOC), which performed femoral implant cavity preparation as programmed preoperatively. Several reports on cementless THA with ROBODOC showed better stem alignment and less variance in limb-length inequality on radiographic evaluation, less incidence of pulmonary embolic events on transesophageal cardioechogram, and less stress shielding on the dual energy X-ray absorptiometry analysis than conventional manual methods. On the other hand, some studies raise issues with active systems, including a steep learning curve, muscle and nerve damage, and technical complications, such as a procedure stop due to a bone motion during cutting, requiring re-registration and registration failure. Semi-active robotic systems, such as Acrobot and Rio, were developed for ease of surgeon acceptance. The drill bit at the tip of the robotic arm is moved by a surgeon's hand, but it does not move outside of a milling path boundary, which is defined according to three-dimensional (3D) image-based preoperative planning. However, there are still few reports on THA with these semi-active systems. Thanks to the advancements in 3D sensor technology, navigation systems were developed. Navigation is a passive system, which does not perform any actions on patients. It only provides information and guidance to the surgeon who still uses conventional tools to perform the surgery. There are three types of navigation: computed tomography (CT)-based navigation, imageless navigation, and fluoro-navigation. CT-based navigation is the most accurate, but the preoperative planning on CT images takes time that increases cost and radiation exposure. Imageless navigation does not use CT images, but its accuracy depends on the technique of landmark pointing, and it does not take into account the individual uniqueness of the anatomy

    Industry and orthopaedic surgeons often partner to develop new technology, which can lead to orthopaedic surgeons having financial conflicts of interest (FCOI). It is essential these FCOI be conveyed clearly to patients. It is unclear, however, whether and to what degree patients understand the ramifications of physician FCOI. We evaluated (1) patients' concerns regarding their surgeon having FCOI or the presence of institutional FCOI, (2) the effect of surgeon FCOI on patients' willingness to have surgery, and (3) patients' understanding of FCOI. We asked 101 patients (66% female) receiving total joint arthroplasty from the orthopaedic practices of two surgeons at an academic health center to complete a descriptive, correlational designed survey at their 6-week followup appointment. The data collected included patient demographics, knowledge of FCOI, and the influence of FCOI on patient attitudes toward surgery and their surgeon. A minority of patients (13%) reported discussing FCOI with prior physicians and only 55% agreed or strongly agreed a surgeon should disclose FCOI. Only 15% of patients believed such conflicts would make them less likely to have their surgeon operate on them. Level of education was weakly correlated (Spearman's rho = 0.29) with patient understanding of FCOI. Overall, patients had a poor understanding of FCOI. Both level of education and previous discussions of FCOI predicted better understanding. This study emphasizes communication of FCOI with patients needs to be enhanced.

    Intraoperative imaging and navigation systems have revolutionized orthopaedic surgery for the spine, joints, and orthopaedic trauma. Imaging modalities such as the isocentric C-arm, O-arm imaging, and intraoperative MRI or navigation systems allow the visualization of surgical instruments and implants relative to a three-dimensional CT image or MRI. Studies show that these technologies lower the rates of implant misplacement and inadequate fracture reduction, thereby improving surgical outcomes and reducing reoperation rates. An additional benefit is reduced radiation exposure compared with that for conventional fluoroscopy. Concerns surrounding adoption of these technologies include cost and increased operating times, but improvements in design and protocol may improve the integration of these imaging modalities into the operating room.

    This paperwork deals with the obtaining and characterisation of new acrylic cements for bone surgery. The final mixture of cement contains derivatives of methacryloyloxyethyl phosphate, methacrylic acid or 2-acrylamido-2-methyl-1-propane sulphonic acid. The idea of using these monomers is sustained by their ability to form ionic bonds with barium, which is responsible for X-ray reflection and by the biocompatibility of these structures. The strategy consists in the obtaining of core-shell structures through heterogeneous polymerisation, which are used for final cement's manufacture. The orthopaedic cements were characterised by SEM, EDX, compression resistance and cytotoxicity assays.

    Full Text Available The management of large bone defects due to trauma, degenerative disease, congenital deformities, and tumor resection remains a complex issue for the orthopaedic reconstructive surgeons. The requirement is for an ideal bone replacement which is osteoconductive, osteoinductive, and osteogenic. Autologous bone grafts are still considered the gold standard for reconstruction of bone defects, but donor site morbidity and size limitations are major concern. The use of bioartificial bone tissues may help to overcome these problems. The reconstruction of large volume defects remains a challenge despite the success of reconstruction of small-to-moderate-sized bone defects using engineered bone tissues. The aim of this paper is to understand the principles of tissue engineering of bone and its clinical applications in reconstructive surgery.

    Despite evidence that decision and communication aids are effective for enhancing the quality of preference-sensitive decisions, their adoption in the field of orthopaedic surgery has been limited. The purpose of this mixed-methods study was to evaluate the perceived value of decision and communication aids among different healthcare stakeholders. Patients with hip or knee arthritis, orthopaedic surgeons who perform hip and knee replacement procedures, and a group of large, self-insured employers (healthcare purchasers) were surveyed regarding their views on the value of decision and communication aids in orthopaedics. Patients with hip or knee arthritis who participated in a randomized controlled trial involving decision and communication aids were asked to complete an online survey about what was most and least beneficial about each of the tools they used, the ideal mode of administration of these tools and services, and their interest in receiving comparable materials and services in the future. A subset of these patients were invited to participate in a telephone interview, where there were asked to rank and attribute a monetary value to the interventions. These interviews were analyzed using a qualitative and mixed methods analysis software. Members of the American Hip and Knee Surgeons (AAHKS) were surveyed on their perceptions and usage of decision and communication aids in orthopaedic practice. Healthcare purchasers were interviewed about their perspectives on patient-oriented decision support. All stakeholders saw value in decision and communication aids, with the major barrier to implementation being cost. Both patients and surgeons would be willing to bear at least part of the cost of implementing these tools, while employers felt health plans should be responsible for shouldering the costs. Decision and communication aids can be effective tools for incorporating patients preferences and values into preference-sensitive decisions in orthopaedics. Future

    Full Text Available Robotics has shown its potential not only in assisting the surgeon during an intervention but also as a tool for training and for surgical procedure's evaluation. Thus, robotics can constitute an extension of simulators that are based on the high capabilities of computer graphics. In addition, haptics has taken a first step in increasing the performance of current virtual reality systems based uniquely on computer simulation and their corresponding interface devices. As a further step in the field of training and learning in surgery, this work describes a robotic experimental workstation composed of robots and specific measuring devices, together with their corresponding control and monitoring strategies for orthopaedic surgery. Through a case study, humerus arthroplasty, experimental evaluation shows the possibilities of having a test bed available for repetitive and quantifiable trials, which make a reliable scientific comparison between different surgical strategies possible.

    Pediatric orthopedics has been a frequently tested topic on the Orthopaedic In-Training Examination (OITE). Our goal was to provide direction for resident education efforts by: (1) analyzing the exam's number, topics, and types of pediatric orthopedic surgery questions; (2) examining references cited in the postexam answer packet supplied by the American Academy of Orthopaedic Surgeons; and (3) examining the efficacy of the Orthopaedic Knowledge Update (OKU): Pediatrics 3 book as a source for answers to the pediatric orthopedic questions. We reviewed 5 years (2002 through 2006) of OITEs and the associated American Academy of Orthopaedic Surgeons' answer packets and assessed the OKU: Pediatrics 3 book for topic relativity. Each question was classified into 1 of 6 categories and labeled with a cognitive taxonomy level: 1 (simple recall), 2 (interpretation of data), or 3 (advanced problem-solving). The 6 categories included: (1) pediatric orthopedic knowledge; (2) knowledge of treatment modalities; (3) diagnosis; (4) diagnosis with recognition of associated conditions; (5) diagnosis with further studies; and (6) diagnosis with treatment. The overall percentage of pediatric questions was 14.1%. The most commonly addressed were pediatric elbow fractures, osteomyelitis, and scoliosis. The most common question types were categories 1 (pediatric orthopedic knowledge) and 6 (diagnosis with treatment). The most frequently referenced textbooks were Lovell and Winter's Pediatric Orthopaedics (31%) and Tachdjian's Pediatric Orthopaedics (16%). The most frequently referenced journals were the Journal of Pediatric Orthopaedics (American) (29%) and the Journal of Bone and Joint Surgery (American) (19%). Using only the OKU: Pediatrics 3 review textbook, 65% of the questions could be answered. Knowledge of the topics more likely to be tested may help the orthopedic educator direct a didactic curriculum geared toward the OITE and American Board of Surgery examinations. Although the

    Full Text Available Abstract Background A recently published meta-analysis comparing metallic staples to sutures in orthopaedic procedures revealed three fold increase in risk for infection in stapled wounds. The studies included in the meta-analysis are at risk of bias due to experimental design limitations. A large randomized controlled trial is proposed to direct orthopaedic surgeons in their choice of wound closure material. Methods/Design A parallel group randomized controlled trial with institutional review board approval will be conducted. Patients will be randomized intraoperatively to have skin wounds closed with sutures or staples. Dressings will be used to maintain blinding outcome assessors. The primary outcome measure will be a composite all-cause wound complication outcome measure composed of: infection, wound drainage, wound necrosis, blistering, dehiscence, suture abscess and material sensitivity reaction. An independent review board blinded to treatment assignment will adjudicate suspected complications based on clinical data. All deceased patients will also be reviewed. An interim analysis of complications will take place after half of the patients have been recruited. All data will be analyzed by a blinded statistician. Dichotomous primary and secondary outcome measures will be analyzed using the Chi-squared statistic. Continuous outcome measures will be analyzed using Student's t-test. Subgroup analysis will compare infection rates using sutures versus staples in each anatomic area (upper extremity, pelvis/acetabulum, hip/femur, knee, ankle. A further subgroup analysis will be conducted comparing trauma patients to elective surgery patients. Non-infected revision surgery will also be compared to primary surgery. Discussion Wound closure material is an afterthought for many orthopaedic surgeons. The combined results of several comparative trials suggests that the choice of wound closure materials may have an impact on the rate of surgical site

  1. Post-operative fever in orthopaedic surgery: How effective is the 'fever workup?'

    Defining the appropriate threshold at which to initiate a fever workup is imperative to promote patient safety, appropriate resource utilization, and antibiotic stewardship. Our group performed a systematic review of the available literature on perioperative fever (POF) workups in orthopaedic patients to evaluate the frequency, timing and utility of blood cultures (BC) and other investigations in the POF workup, to determine the clinical relevance of any infections and to evaluate their cost effectiveness. Studies were identified by searching MEDLINE, EMBASE, Pubmed, Cochrane and Google Scholar for articles through September 2016. Forty-nine articles were retrieved and 22 articles met the pre-determined inclusion criteria. Proportions of positive studies were noted and averaged using random effects analysis. Post-operative pyrexia ranged in prevalence between 8.1% and 87.3%. The studies routinely performed during a fever workup had wide ranges of diagnostic yield, including chest X-rays from 0% to 40%, urinalyses from 8.2% to 38.7%, urine cultures from 0% to 22.4% and BC from 0% to 13.3%. Only two patients with positive BC developed clinical sepsis. Cost per fever evaluation ranged from $350 to $950. The findings of this review suggest that early post-operative fever is an expected event following orthopaedic surgery. Based on the available literature, any kind of workup in the absence of localizing symptoms in the third post-operative day or before is unwarranted and is an inappropriate use of hospital resources.

  2. [What's new in orthopaedic surgery: hopes and facts in total hip and spine arthroplasty].

    2007-01-01

    Progress in implant design and surface properties have improved long-term survival of total hip prosthesis and lowered the incidence of dislocation. New materials, particularly ceramics and metals, decrease the risk for implant loosening because they induce less particle disease than polyethylene debris. These new materials have been submitted to simulator studies before being released for clinical use. They have been used since a sufficient amount of time in clinical practice to consider them as being part of our current armamentarium. They enable the orthopaedic surgeon to tailor the optimal hip prosthesis to each patient's need, depending on his/her bone stock, activity level and life expectancy. Disk prostheses and the general concept of non fusion surgery in spine surgery seems attractive, since intervertebral fusion carries a number of drawbacks, particularly at the level of adjacent segments. However, the documented follow-up of non-fusion spine surgery is at present insufficient to consider a widespread use of these new technologies. Their own possible complications are largely unknown and they do not replace bone fusion in the most clear-cut accepted indications for spine surgery. The use of disk prostheses should therefore be strictly limited according to present knowledge.

    Full Text Available The aim of the study was to test the hypothesis that epidural administration of morphine with bupivacaine provides more intense and sufficient perioperative analgesia compared with parenterally administrated butorphanol during orthopaedic surgery. Sheep were assigned to group C (control group, 6 sheep and group E (epidural, 5 sheep. Sheep from group C were pre-medicated with midazolam (0.3 mg/kg, i.m. and butorphanol (0.2 mg/kg, i.m.. Propofol was used for induction of general anesthesia in both groups. Sheep from group E were pre-medicated with midazolam, but without butorphanol. Sacrococcegeal epidural analgesia with morphine (0.1 mg/kg and bupivacaine (1 mg/kg was performed. We detected a significant increase in heart rate (19%, p=0.021 during surgery in group C. Two hours after surgery, the heart rate was 14.9% lower than prior to surgery in group E (p=0.017. In group E, throughout the surgery, we measured an insignificant increase in respiratory rate of 1.99%. In the same group, 120 minutes post surgery, we measured an increase in respiratory rate of 14.7%, while in group C there was a smaller increase of only 10.9%. The result from both groups was insignificant (p>0.05. The consumption of isoflurane in group C was higher than in group E by 27.3% (p=0.0043. The mean MAC was in group C higher by 27.6% as it was in group E (0.75% ± 0.25, 0.95 ± 0.3 in Group E and C, respectively. This distinction, according to the Mann-Whitney test, was not significant (p=0.329.

    Patient blood management (PBM) can prevent preoperative anaemia, but little is known about practice in Europe. To assess the pre and postoperative prevalence and perioperative management of anaemia in patients undergoing elective orthopaedic surgery in Europe. An observational study; data were collected from patient records via electronic case report forms. Seventeen centres in six European countries. Centres were stratified according to whether they had a PBM programme or not. One thousand five hundred and thirty-four patients undergoing major elective hip, knee or spine surgery [49.9% hip, 37.2% knee, 13.0% spine; age 64.0 years (range 18 to 80), 61.3% female]. Prevalence of preoperative (primary endpoint) and postoperative anaemia [haemoglobin (Hb) anaemia management, time to first blood transfusion and number of transfused units. Data are shown as mean (SD) or median (interquartile range). Anaemia prevalence increased from 14.1% preoperatively to 85.8% postoperatively. Mean Hb decrease was 1.9 (1.5) and 3.0 (1.3) g dl in preoperatively anaemic and nonanaemic patients, respectively (P anaemia was less frequent (8.0 vs. 18.5%; P anaemia correction (mainly transfusion) was given to 34.3%. Intraoperatively, 14.8% of preoperatively anaemic and 2.8% of nonanaemic patients received transfusions [units per patient: 2.4 (1.5) and 2.2 (1.4), median time to first intraoperative transfusion: 130 (88, 158) vs. 179 (135, 256) min; P < 0.001]. Postoperative complications were more frequent in preoperatively anaemic vs. nonanaemic patients (36.9 vs. 22.2%; P = 0.009). Most patients who underwent elective orthopaedic surgery had normal preoperative Hb levels but became anaemic after the procedure. Those who were anaemic prior to surgery had an increased intraoperative transfusion risk and postoperative complication rate. PBM measures such as iron status assessment and strategies to avoid transfusion are still underused in Europe.

    To explore how older people maintained and improved their self-efficacy in managing home rehabilitation and their adherence to rehabilitation exercise programmes following orthopaedic surgery. Successful postoperative orthopaedic rehabilitation for older people depends on building their confidence about adherence to exercise programmes designed to improve their functional performance. Many older people, however, do not reach a satisfactory level of functional ability before discharge and some fail to adhere to their rehabilitation exercise programme at home. This contributes to a reduced quality of life. Although many studies report the influences of self-efficacy, little is known about the factors that help rebuild self-efficacy beliefs towards postdischarge exercise following orthopaedic surgery. A descriptive exploratory qualitative study. Semi-structured interviews were used with 15 older people who had returned to their homes following orthopaedic surgery. Findings emphasise the importance of social support from family, friends and community to nurture self-efficacy. Accessing personal beliefs and attitudes, adaptive strategies and goal setting were all sources and ways participants rebuilt their confidence and motivation in regard to adhering to a rehabilitation programme. Facilitating self-efficacy assists older people to manage home rehabilitation and planning care with family and friends to create a support system in early discharge planning allows a safer and smoother recovery. Rehabilitation programmes and education should encourage an understanding of self-efficacy as a means to improve individual functional performance. © 2012 Blackwell Publishing Ltd.

    The impact of perioperative hyperglycemia in orthopaedic surgery is not well defined. We hypothesized that hyperglycemia is an independent risk factor for thirty-day surgical-site infection in orthopaedic trauma patients without a history of diabetes at hospital admission. Patients eighteen years of age or older with isolated orthopaedic injuries requiring acute operative intervention were studied. Patients with diabetes, injuries to other body systems, a history of corticosteroid use, or admission to the intensive care unit were excluded. Blood glucose values were obtained, and hyperglycemia was defined in two ways. First, patients with two or more blood glucose levels of ≥200 mg/dL were identified. Second, the hyperglycemic index, a validated measure of overall glucose control during hospitalization, was calculated for each patient. A hyperglycemic index of ≥1.76 (equivalent to ≥140 mg/dL) was considered to indicate hyperglycemia. The primary outcome was thirty-day surgical-site infection. Multivariable logistic regression models evaluating the effect of the markers of hyperglycemia, after controlling for open fractures, were constructed. Seven hundred and ninety patients were identified. There were 268 open fractures (33.9%). Twenty-one thirty-day surgical-site infections (2.7%) were recorded. Age, race, comorbidities, injury severity, and blood transfusion were not associated with the primary outcome. Of the 790 patients, 294 (37.2%) had more than one glucose value of ≥200 mg/dL. This factor was associated with thirty-day surgical-site infection, with thirteen (4.4%) of the 294 patients with that indication of hyperglycemia having a surgical-site infection versus eight (1.6%) of the 496 patients without more than one glucose value of ≥200 mg/dL (p = 0.02). One hundred and thirty-four (17.0%) of the 790 patients had a hyperglycemic index of ≥1.76, and this was also associated was thirty-day surgical-site infection (ten [7.5%] of 134 versus eleven [1

    Perioperative cerebrovascular accidents (CVAs) are one of the leading causes of patient morbidity, mortality, and medical costs. However, little is known regarding the rates of these events and risk factors for CVA after elective orthopaedic surgery. Our goals were to (1) establish the national, baseline proportion of patients experiencing a 30-day CVA and the timing of CVA; and (2) determine independent risk factors for 30-day CVA rates after common elective orthopaedic procedures. Patients undergoing elective TKA, THA, posterior or posterolateral lumbar fusion, anterior cervical discectomy and fusion, and total shoulder arthroplasty, from 2006 to 2012, were identified from the American College of Surgeons National Surgical Quality Improvement Program(®) database. A total of 42,150 patients met inclusion criteria. Thirty-day CVA rates were recorded for each procedure, and patients were assessed for characteristics associated with CVA through univariate analysis. Multivariate regression models were created to identify independent risk factors for CVA. A total of 55 (0.13%) patients experienced a CVA within 30 days of the procedure, occurring a median of 2 days after surgery (range, 1-30 days) with 0.08% of patients experiencing a CVA after TKA, 0.15% after THA, 0.00% after single-level anterior cervical discectomy and fusion, 0.38% after multilevel anterior cervical discectomy and fusions, 0.20% after single-level posterior or posterolateral lumbar fusion, 0.70% after multilevel posterior or posterolateral lumbar fusion, and 0.22% after total shoulder arthroplasty. Independent risk factors for CVA included age of 75 years or older (odds ratio [OR], 2.50; 95% CI, 1.44-4.35; p = 0.001), insulin-dependent diabetes mellitus (OR, 3.08; CI, 1.47-6.45; p = 0.003), hypertension (OR, 2.71; CI, 1.19-6.13; p = 0.017), history of transient ischemic attack (OR, 2.83; CI, 1.24-6.45; p = 0.013), dyspnea (OR, 2.51; CI, 1.30-4.86; p = 0.006), chronic obstructive pulmonary disease

    incidents. Discussion Orthopaedic surgery is a high volume specialty with major technical complexity in terms of equipment demands and staff training and familiarity. There is therefore an increased propensity for errors to occur. Wrong-site surgery still occurs in this specialty and is a potentially devastating situation for both the patient and surgeon. Despite the limitations of inclusion and reporting bias, our study highlights the need to match technical precision with patient safety. Tools such as the WHO surgical checklist can help us to achieve this.

    Security and quality of the Medicinal Therapy are one of the most important objectives of the April 6th, 2011 order. The objective is to realize this study of the risks incurred by patients related to management and security of medicinal therapy in order to establish a plan to reduce the risks of drug's dispensation. The method of the Preliminary Risk Analysis (PRA) has been implemented by a multidisciplinary group in a hospital service of orthopaedic surgery. The study focused on the dispensation phase of medicinal circuit. This analysis revealed 148 scenarii, 35 were criticality unacceptable. Fifty-four initial risk control actions were proposed and their stress levels to put them in place were evaluated. The main measures of risk management are: training, information, communication, computerization, automation, dual control, updating the documentation system, drug reconciliation and respect for Best Practices Hospitallers (BPH). Risk management requires a significant human and financial investment as well as, material resources and multidisciplinary expertise in order to offer the best solutions.

    Full Text Available The brachial plexus in infraclavicular region can be blocked by various approaches. Aim of this study was to compare two approaches (coracoid and clavicular regarding success rate, discomfort during performance of block, tourniquet tolerance and complications. The study was randomised, prospective and observer blinded. Sixty adult patients of both sexes of ASA status 1 and 2 requiring orthopaedic surgery below mid-humerus were randomly assigned to receive nerve stimulator guided infraclavicular brachial plexus block either by lateral coracoid approach (group L, n = 30 or medial clavicular approach (group M, n = 30 with 25-30 ml of 0.5% bupivacaine. Sensory block in the distribution of five main nerves distal to elbow, motor block (Grade 1-4, discomfort during performance of block and tourniquet pain were recorded by a blinded observer. Clinical success of block was defined as the block sufficient to perform the surgery without any supplementation. All the five nerves distal to elbow were blocked in 77 and 67% patients in groups L and M respectively. Successful block was observed in 87 and 73% patients in groups L and M, respectively (P > 0.05. More patients had moderate to severe discomfort during performance of block due to positioning of limb in group M (14 vs. 8 in groups M and L. Tourniquet was well tolerated in most patients with successful block in both groups. No serious complication was observed. Both the approaches were equivalent regarding success rate, tourniquet tolerance and safety. Coracoid approach seemed better as positioning of operative limb was less painful, coracoids process was easy to locate and the technique was easy to learn and master.

    The preoperative and postoperative wound-healing capacity of 23 patients undergoing elective major abdominal, thoracic or urological surgery was tested objectively by the subcutaneous accumulation of hydroxyproline and proline in an expanded polytetrafluoroethylene (ePTFE) tube. Before scheduled...... surgery two ePTFE tubes were implanted for removal after 5 and 10 days. This was repeated for each patient immediately after surgery. After 10 days a higher amount of hydroxyproline was measured before than after operation (median 2.91 (range 0.37-14.45) versus 1.45 (range 0.26-6.94) micrograms/cm, P = 0...

    Background In acutely ill patients with new onset hyperglycaemia, plasma glucose cannot reliably distinguish between stress hyperglycaemia and undiagnosed diabetes mellitus. We, therefore, investigated the diagnostic reliability of glycated haemoglobin (HbA1c) in acute illness by prospectively evaluating the effect of the systemic inflammatory response, as provoked by elective orthopaedic surgery, on HbA1c. Methods HbA1c and serum C-reactive protein concentrations were compared before and two days after elective knee or hip surgery in 30 patients without diabetes. C-reactive protein was used to assess the systemic inflammatory response. Results The mean (standard deviation) serum C-reactive protein increased following surgery (4.8 [7.5] vs. 179.7 [61.9] mg/L; P<0.0001). HbA1c was similar before and after surgery (39.2 [5.4] vs. 38.1 [5.1] mmol/moL, respectively; P = 0.4363). Conclusions HbA1c is unaffected within two days of a systemic inflammatory response as provoked by elective orthopaedic surgery. This suggests that HbA1c may be able to differentiate newly presenting type 2 diabetes mellitus from stress hyperglycaemia in acutely ill patients with new onset hyperglycaemia.

  15. Far cortex automatic detection aimed for partial or full bone drilling by a robot system in orthopaedic surgery

    Full Text Available Far cortex detection during the bone-drilling process is a specific task in orthopaedic surgery. Any errors in its execution could damage the cortex wall from the inside, which often causes additional trauma even with a fatal result. Here we present some functionality enhancements of the drilling orthopaedic robot ODRO concerning the solution of the far cortex detection problem. The solution is based on software control of the thrust force applied to the bone during the drilling process. A new algorithm is created and its software realisation is provided. Experimental results are presented which verify and confirm the new functional characteristics of the robot. The risk of far cortex damage may be avoided by robot application and such precise operations may guarantee better success.

    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.

    2011-12-01

    This paper presents a new thermal model for bone drilling with applications to orthopaedic surgery. The new model combines a unique heat-balance equation for the system of the drill bit and the chip stream, an ordinary heat diffusion equation for the bone, and heat generation at the drill tip, arising from the cutting process and friction. Modeling of the drill bit-chip stream system assumes an axial temperature distribution and a lumped heat capacity effect in the transverse cross-section. The new model is solved numerically using a tailor-made finite-difference scheme for the drill bit-chip stream system, coupled with a classic finite-difference method for the bone. The theoretical investigation addresses the significance of heat transfer between the drill bit and the bone, heat convection from the drill bit to the surroundings, and the effect of the initial temperature of the drill bit on the developing thermal field. Using the new model, a parametric study on the effects of machining conditions and drill-bit geometries on the resulting temperature field in the bone and the drill bit is presented. Results of this study indicate that: (1) the maximum temperature in the bone decreases with increased chip flow; (2) the transient temperature distribution is strongly influenced by the initial temperature; (3) the continued cooling (irrigation) of the drill bit reduces the maximum temperature even when the tip is distant from the cooled portion of the drill bit; and (4) the maximum temperature increases with increasing spindle speed, increasing feed rate, decreasing drill-bit diameter, increasing point angle, and decreasing helix angle. The model is expected to be useful in determination of optimum drilling conditions and drill-bit geometries.

    The objective of the present study was to determine the potency of dexmedetomidine in relation to medetomidine in sheep undergoing orthopaedic surgery by comparing the anaesthetic requirements and cardiovascular changes at a dose relationship that represented equipotency in vitro. Twenty-four non-pregnant, female sheep were used. The study was carried out as a blind, randomized, experimental trial. Group 1 received 5 micrograms/kg bodyweight (BW) dexmedetomidine and group 2 received 10 micrograms/kg BW medetomidine intravenously 5 min prior to induction of anaesthesia. Anaesthesia was induced with ketamine (2.0 mg/kg BW intravenously) and maintained with isoflurane in 100% oxygen. End expired anaesthetic concentration (FEIso), end expired carbon dioxide concentration (FECO2), respiratory frequency (fR), direct arterial blood pressures, heart rates (HR) and arterial blood gases were monitored. Data were averaged over time and tested for differences between groups by independent t-tests, and analysis of variance for repeated measures. Average FEIso concentrations required to maintain a surgical plane of anaesthesia were not different between groups (1: 1.02 +/- 0.04%; 2: 0.99 +/- 0.07%). There was no difference in HR, arterial blood pressures, fR, FECO2 and arterial blood gases between groups. Average mean PaO2 were 279.54 +/- 113.37 mmHg and 220.21 +/- 102.15 mmHg with individual minimum values of 27.2 mmHg and 58.5 mmHg in groups 1 and 2, respectively. In conclusion, intravenous dexmedetomidine at 5 micrograms/kg BW and medetomidine at 10 micrograms/kg BW have the same effects on isoflurane requirements and cardiopulmonary parameters in sheep, indicating an equipotent dose relationship. Both preparations induced moderate to severe hypoxaemia in individual sheep.

  1. Tourniquet-applied upper limb orthopaedic surgery results in increased inflammation and changes to leukocyte, coagulation and endothelial markers.

    Stephen F Hughes

    Full Text Available PURPOSE: During this pilot clinical study, patients scheduled for elective tourniquet-applied upper limb orthopaedic surgery were recruited to investigate the effects of surgery on various biological markers (n = 10 patients. METHODS: Three venous blood samples were collected from the arm at the ante-cubital fossa, at baseline (pre-operatively, 5 and 15 minutes after reperfusion (post-operatively. Neutrophil and monocyte leukocyte sub-populations were isolated by density gradient centrifugation techniques. Leukocyte activation was investigated by measuring the cell surface expression of CD62L (L-selectin, CD11b (Mac-1 and the intracellular production of hydrogen peroxide (H2O2, via flow cytometry. C-reactive protein (CRP was measured using a clinical chemistry analyser. Plasma concentrations of protein C and von Willebrand factor (vWF were measured using enzyme-linked fluorescent assays (ELFA. RESULTS: Following tourniquet-applied upper limb orthopaedic surgery, there was a decrease in neutrophil CD62L expression (p = 0.001, an increase in CD11b expression and in the intracellular production of H2O2 by neutrophils and monocytes (p<0.05. An increase in CRP concentration (p<0.001, a decrease in protein C concentration (p = 0.004, with a trend towards elevated vWF levels (p = 0.232 were also observed during this time. CONCLUSIONS: Conventionally, patients undergoing orthopaedic surgery have been monitored in the peri-operative period by means of CRP, which is a non-specific marker of inflammation. This test cannot differentiate between inflammation due to current or pre-existing disease processes and the development of ischaemia-reperfusion injury surgery. The findings from this study suggest that markers such as CD11b, protein C and H2O2 may provide alternative ways of assessing leukocyte and coagulation activation peri-operatively. It is proposed that by allowing orthopaedic surgeons access to laboratory markers such as CD11b, protein C and H2O2

    Enhanced recovery programs (ERP) represent a multimodal approach to perioperative patient care. The benefits of ERP are well demonstrated in colorectal surgery and Enhanced Recovery After Surgery (ERAS®) programs, that epitomise the ERP concept, have being introduced in different specialties, including vascular, gastric, pancreatic, urogynecologic and orthopaedic surgery. However, no ERP has been proposed for head and neck surgery. We developed an expert-opinion-based ERP for laryngeal surgery based on the key principles of colorectal surgery ERAS®. Twenty-four patients undergoing major laryngeal surgery (total and partial laryngectomies or surgical removal of oropharyngeal tumour with muscle flap reconstruction) were treated according to such an ERP protocol, which differed under several respects from our previous standard practice (described in 70 consecutive patients who underwent major laryngeal surgery before ERP implementation. The adherence rate to the different ERP items is reported. Adherence to ERP items was high. Nutritional assessment, antibiotic prophylaxis, postoperative nausea and vomit (PONV) prophylaxis and postoperative speech therapy targets were applied as required in 100% of cases. Some ERP items (antibiotic prophylaxis, intraoperative infusion rate, and postoperative speech therapy) were already frequently implemented before ERP adoption. Postoperative medical complications occurred in 8.3% of patients. Our expert-opinion-based ERP protocol for major laryngeal surgery proved feasible. The degree of benefit deriving from its implementation has yet to be assessed. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

    By December 1914, overwhelming numbers of soldiers with infected musculoskeletal wounds had filled hospitals in France and Britain. Frequently initial management had been inadequate. In 1915, patients with orthopaedic wounds were segregated for the first time when Robert Jones established an experimental orthopaedic unit in Alder Hey Hospital, Liverpool. In 1916 he opened the first of 17 orthopaedic centres in Britain to surgically treat and rehabilitate patients. Henry Gray from Aberdeen emerged as the leading authority in the management of acute musculoskeletal wounds in casualty clearing stations in France and Flanders. Gray had particular expertise in dealing with compound fractures of the femur for which he documented an 80% mortality rate in 1914-15.

    Effective and timely communication is important for any surgical specialty to function. The use of smartphones is prevalent amongst doctors. Numerous smartphone applications offer the potential for fast and cost-effective communication. WhatsApp is a commonly used application that is free, easy to use, and capable of text and multimedia messaging. We report on the use of WhatsApp over a six month period in our unit. WhatsApp communication between non-consultant members of an orthopaedic team over a six-month period was analysed. Both the phones and the WhatsApp application were password-protected, and patient details were anonymised. A series of 20 communications using the hospital pager system and the telephone system were also analysed. A total of 5,492 messages were sent during the six-month period and were part of 1,916 separate communication events. The vast majority of messages, 5,090, were related to patient care. A total of 195 multimedia messages were sent and these included images of radiographs and wounds. When using the hospital telephones, the length of time spent on a communication averaged 5.78 minutes and using the hospital pager system averaged 7.45 minutes. Using the WhatsApp messaging system has potentially saved up to 7,664 minutes over the study period. All participants found WhatsApp easy to use and found it to be more efficient than the traditional pager system Conclusion: Compared to the traditional pager systems, the use of WhatsApp is easy, inexpensive, and reliable and can help improve the efficiency of communication within a surgical team.

    Collection and analysis of clinical data can help orthopaedic surgeons to practice evidence based medicine. Spreadsheets and offline relational databases are prevalent, but not flexible, secure, workflow friendly and do not support the generation of standardized and interoperable data. Additionally these data collection applications usually do not follow a structured and planned approach which may result in failure to achieve the intended goal. Our purposes are (1) to provide a brief overview of EDC systems, their types, and related pros and cons as well as to describe commonly used EDC platforms and their features; and (2) describe simple steps involved in designing a registry/clinical study in DADOS P, an open source EDC system. WHERE ARE WE NOW?: Electronic data capture systems aimed at addressing these issues are widely being adopted at an institutional/national/international level but are lacking at an individual level. A wide array of features, relative pros and cons and different business models cause confusion and indecision among orthopaedic surgeons interested in implementing EDC systems. WHERE DO WE NEED TO GO?: To answer clinical questions and actively participate in clinical studies, orthopaedic surgeons should collect data in parallel to their clinical activities. Adopting a simple, user-friendly, and robust EDC system can facilitate the data collection process. HOW DO WE GET THERE?: Conducting a balanced evaluation of available options and comparing them with intended goals and requirements can help orthopaedic surgeons to make an informed choice.

  8. Comparison of 0.5% Bupivacaine and 0.5% Ropivacaine epidurally in lower limb orthopaedic surgeries

    2017-01-01

    Full Text Available Background: Ropivacaine in equi-potent concentrations with bupivacaine, the degree of motor blockade is less pronounced with ropivacaine, and there is a greater propensity for blocking pain transmitting A-delta and C fibres rather than A-α motor fibres. It appears to have most of the blocking characteristics of bupivacaine. So we have undertaken the study to compare ropivacaine 0.5% (20ml and bupivacaine 0.5% (20ml for epidural anaesthesia in patients undergoing lower limb orthopaedic surgeries. Methods: This double-blind, randomized study involves 60 patients who were undergone orthopaedic surgery, having ASA-I or ASA-II physical status. Out of 60, 30 patients received 20 ml of 0.5% ropivacaine and 30 patients received 20 ml of 0.5% bupivacaine at the L3, 4 interspace. Parameters measured were the onset time, duration and spread of sensory block, the onset time, peak time, duration and degree of motor block, the quality of anaesthesia and the heart rate and blood pressure profile during block onset. Results: Epidurally, Ropivacaine in comparison to Bupivacaine provides quicker onset, early peak effect and prolonged duration of sensory block and shorter duration of motor block. Ropivacaine provides prolonged effective analgesia. It reduces requirement of rescue analgesics and related side effects. Conclusions: Ropivacaine 0.5% is safer and effective alternative to Bupivacaine in epidural anaesthesia and post operative pain relief.

    The general shortage of medical doctors in Germany can also be felt in the area of trauma and orthopaedics. Medical elective placements, in Germany known as "Famulatur", are sensitive interfaces between the theoretical university studies and the practical medical workplace. In this research project, the aim was to study how medical students perceive these types of placements and if it alters their decision making when planning their further career. During the summer term of 2012, 9079 medical students answered an online questionnaire. Of these, the subgroup was evaluated that had had a placement of at least 4 weeks in the field of trauma and orthopaedics. Overall, 37 test items about this placement and further career steps were included in this study. Groups were evaluated separately by the item "I am considering a career in trauma and orthopaedics" (PJ-Ja) versus "I am not considering a career in trauma and orthopaedics" (PJ-Nein). Overall 397 students were included in this study; 55 % were female. 267 (67.3 %) stated: "I am considering a career in trauma and orthopaedics"; 130 (32.7 %) were not. There was no significant difference in age or sex between these groups (sex: χ²= 2.50, p = 0.114; age: F[1.93]< 1, p = 0.764). Specific and statistically significant differences between those groups were found in the items team integration, ward climate, qualification of teaching, training for specific knowledge in the field, practical aspects of the tasks performed, general planning and structure of the elective achievement of the teaching goals. Knowledge of satisfaction during medical elective placements is essential if one aims to inspire students for a specific medical profession. Instructors who can identify weaknesses and deficits in their training regime can therefore in the future increase the number of medical doctors who choose their speciality. The foundation of personal development has to be laid very early in the career of medical students

    The goal of the Patient Protection and Affordable Care Act (PPACA) was to expand patient access to health care. Since the rollout of the PPACA, Medicaid patients have demonstrated difficulty obtaining appointments in some specialty care settings. To assess the effect of insurance type (Medicaid and private) on patient access to orthopaedic surgery sports medicine specialists for a semiurgent evaluation of a likely operative bucket-handle meniscus tear. The study was designed to determine whether disparities in access exist since the PPACA rollout. Cohort study; Level of evidence, 2. The design was to call 180 orthopaedic surgery sports medicine specialists in 6 representative states (California, Ohio, New York, Florida, Texas, and North Carolina) between June 2015 and December 2015. An appointment was requested for the caller's fictitious 25-year-old-brother who had suffered a bucket-handle meniscus tear. Each office was called twice to assess the ease of obtaining an appointment: once for patients with Medicaid and once for patients with private insurance. For each call, data pertaining to whether an appointment was given, wait times, and barriers to receiving an appointment were recorded. A total of 177 surgeons were called within the study period. Overall, 27.1% of offices scheduled an appointment for a patient with Medicaid, compared with 91.2% (P < .0001) for a patient with private insurance. Medicaid patients were significantly more likely to be denied an appointment due to lack of referral compared with private patients (40.2% vs 3.7%, P < .0001), and Medicaid patients were more likely to experience longer wait times for an appointment (15 vs 12 days, P < .029). No significant differences were found in patients' access to orthopaedic surgery sports medicine specialists between Medicaid-expanded and -nonexpanded states. Medicaid reimbursement for knee arthroscopy with meniscus repair was not significantly correlated with appointment success rate or patient

    Full Text Available Background: A high level of soluble thrombomodulin (sTM is associated with a lower risk of thrombosis but can cause severe bleeding after operations. Deep vein thrombosis (DVT and blood loss are serious threats after orthopedic surgery. The aim of our pilot study was to evaluate the effect of the preoperative level of sTM on coagulation and inflammation as well as the blood loss and the development of symptomatic DVT after total large joint replacement. Methods and Results: In all patients (n=50 who underwent total hip or knee replacement, sTM, PrC, D-dimer, vWF, CRP, and platelets were determined before and after the operation. According to the preoperative sTM level, patients were divided into 2 groups: the thrombomodulin low (TML group (n=25 and thrombomodulin high (TMH group (n=25. The concentration of sTM was 4.4 [3.4, 4.7] ng/ml in the TML-group and 8.7[7.3, 10.6] ng/ml in the TMH-group. After surgery, D-dimer, vWF, platelet count and CRP were higher and total blood loss was lower in the TML group. In the TML-group, a symptomatic DVT was detected in 3(12% patients; in the TMH-group, a symptomatic DVT was identified only in 1(4% case. Conclusion: These findings support the important role of sTM in coagulation, inflammation, bleeding, and presumably in venous thrombosis after major orthopedic surgery.

    The purpose of this study was to develop and test a standard method of collecting saliva from postoperative patients. Saliva was collected from patients following major abdominal surgery from both parotid glands in intraoral cups and measured in milliliters. Trained research nurses stimulated saliva production with lemon juice and collected saliva at 4 time points on postoperative day 2. Collection time was measured with a stopwatch, and flow rate was calculated by dividing the amount in milliliters by collection time in minutes. Attrition was 9% due to ineligibility after enrollment and 1 withdrawal. In participating patients (n = 68), there were 272 tests planned and 28% were missing. The reasons were postoperative health problems, hospital discharge, and not wanting to be bothered. When saliva collection attempts were made, three-fourths were successful, but the remainder resulted in "dry mouth." Milliliters, minutes, and flow rate were calculated with and without those with dry mouth. Mean flow rates were 0.23 to 0.33 ml/min excluding those with dry mouth and 0.17 to 0.24 ml/min including those with dry mouth. Saliva variables were correlated with antihypertension medications, opioids, opioid side effects, and length of surgery, but statistically significant correlations were not found consistently at all 4 time points. The findings suggest that nurse-researchers studying biological markers can successfully collect saliva from postoperative patients if they recognize the difficulties and make efforts to minimize and control for them.

    Senior medical students frequently rotate at orthopaedic residency programs away from their home medical schools. However, to our knowledge, the perspective of program directors (PDs) and applicants on the value, objectives, and costs of these rotations has not been studied. Surveys evaluating the frequency, costs, benefits, and objectives of away rotations were distributed to all orthopaedic residency PDs in the United States and applicants in the 2014-2015 Match cycle. Data analysis was conducted to perform inferential and descriptive statistics; comparisons were made between and among PD and applicant groups using two-tailed means Student t-test and analysis of variance. A total of 74 PD (46.0%) and 524 applicant (49.3%) responses were obtained from a national distribution. Applicants completed an average of 2.4 away rotations, with an average cost of $2,799. When stratified on self-reported likelihood of Matching, there were no substantial differences in the total number of rotations performed. The only marked differences between these groups were the United States Medical Licensing Examination Step 1 score and the number of applications to residency programs. PDs reported that significantly fewer rotations should be allowed, whereas applicants suggested higher limits (2.42 rotations versus 6.24, P < 0.001). PDs and applicants had similar perspectives on the value of away rotations; both groups reported more value in finding a "good fit" and making a good impression at the program and placed less value on the educational impact. The value of orthopaedic away rotations appears more utilitarian than educational for both PDs and applicants. Rotations are performed regardless of perceived likelihood of Matching and are used by students and programs to identify a "good fit." Therefore, given the portion of an academic year that is spent on orthopaedic rotations, findings showing perceived low educational value and marked discrepancies between the expected number of

Routine thromboprophylaxis is still unequivocal prescription is problematic due to perception of low VTE incidence among Asian population. This study aims to investigate the incidence of VTE and thromboprophylaxis prescription among patients undergoing major surgery in a Singapore hospital.Methods: This was a cross-sectional study. Data were obtained from medical record of 1,103 patients who had underwent major orthopaedic or abdominal surgery in 2011-2012 at Khoo Teck Puat Hospital, Singapore. Incidence of VTE events either in the same admission or re-admission in less than one month time were noted as study parameters.Results: Incidence of VTE was 2.1% (95% CI: 1.67 - 2.53 of which 1.3% and 0.8% were DVT and PE cases respectively. Age, gender, history of VTE, ischemic heart disease, and mechanical prophylaxis were associated with VTE incidence based on bivariate analysis. The prescription of pharmacological thromboprophylaxis was associated with prior anticoagulant medication, type of surgery, and incidence of new bleeding. Conclusion: Subsequent to major surgeries, VTE is as common in Asian patients as published data in other populations. Pharmacologic thromboprophylaxis should be considered as recommended in non-Asian guidelines.Keywords: thromboprophylaxis, venous thromboembolism

    The aim of this article was to identify the literature that examined and explored physical and psychological morbidity and patient and family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. A systematic review of the literature using the databases MEDLINE, CINAHL and EMBASE was undertaken. The papers were examined using title and abstract for relevance to the primary and secondary outcomes. The primary outcome of interest was family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery. The search yielded 275 records after removing any duplicates; eight studies were considered eligible and were reviewed as full text. Following full review, none of the studies was included in this article. To conclude, there were no papers that investigated or examined the concept of resilience in relation to the management of acute post-surgical orthopaedic wounds. Four of the papers identified, following the review process, did discuss quality of life outcomes and how these may be improved following wound development; most papers focused on the management of chronic wounds. It is apparent from the review that there is no evidence currently available that explores patient and family caregiver resilience following acute wound development and/or wound blistering post orthopaedic surgery.

    Full Text Available Abstract Background Zambia's governmental health system suffers from shortage of surgical supplies and poor management skills for the sparse resources at hand. The situation has been worsened by the dual epidemics of HIV disease and tuberculosis. On the other hand the private medical sector has benefited greatly from less bureaucracy under the goverment of the Movement for Multi-party Democracy. Discussion The Zambian-Italian Orthopaedic Hospital in Lusaka is a well organized small unit providing free treatment of physically disabled children. The running costs are met from the fees charged for private consultations, supplemented by donations. State of the art surgical techniques are being used for congenital and acquired musculo-skeletal abnormalities. Last year 513 patients were operated upon free of charge and 320 operations were performed on private patients.

    Small numbers of organisms can cause orthopaedic implant infections, which give rise to a considerable degree of morbidity and also mortality. The periprosthetic infection rates have been shown to correlate with the number of airborne bacteria within 30 cm of the wound. This is influenced by factors such as the number of operating theatre personnel, their clothing and the type of ventilation system used. Guidance on routine bacteriological monitoring of ultraclean air theatres, based on the Department of Health document Health Technical Memorandum 2025, is discussed. Factors important in minimizing the number of postoperative implant infections such as the use of ultraclean air, ultraviolet radiation, different types of surgical clothing, prophylactic antibiotics and host-related factors are also discussed. The importance of proper scientific investigation into the effectiveness of practical preventative measures in the operating room is emphasized.

    An increasing number of orthopaedic surgeons are using computer aided planning tools for bone removal applications. The aim of the study was to consolidate a set of generic functions to be used for a 3D computer assisted planning or simulation. A limited subset of 30 surgical procedures was analyzed and verified in 243 surgical procedures of a surgical atlas. Fourteen generic functions to be used in 3D computer assisted planning and simulations were extracted. Our results showed that the average procedure comprises 14 ± 10 (SD) steps with ten different generic planning steps and four generic bone removal steps. In conclusion, the study shows that with a limited number of 14 planning functions it is possible to perform 243 surgical procedures out of Campbell's Operative Orthopedics atlas. The results may be used as a basis for versatile generic intraoperative planning software.

    Periodic review of the published research in pediatric orthopaedics is helpful to evaluate the state of scientific methodology. The purpose of this paper was to review the levels of evidence (LOE) and types of evidence (TOE) published in the Journal of Pediatric Orthopaedics (JPO) from 2009 to 2013 and to compare the percentage of articles with each LOE to pediatric orthopaedic articles published in the Journal of Bone and Joint Surgery-American Volume (JBJS) during the same time. All articles published in JPO from January 1, 2009, to December 31, 2013, were reviewed. Articles were classified as scientific studies, case reports, commentaries/letters to editor, reviews, expert opinion, and basic science articles. All scientific articles in the pediatrics section of the online version of JBJS were reviewed. If listed, the LOE was recorded from all clinical scientific studies. In addition, articles were abstracted for self-reported TOE (therapeutic, diagnostic, prognostic, or economic analysis). We found 850 citations in JPO over the study period; 646 (76%) were identified as scientific articles and, of those, 552 (85%) had a LOE listed. There were 18 level I articles (3%), 101 level II (18%), 184 level III (34%), and 289 level IV (45%). The TOE was listed in 213 (39%) articles: 114 (54%) therapeutic, 37 (17%) prognostic, 55 diagnostic (26%), and 7 (3%) economic analysis. Comparing 2009 to 2013, the percentage of scientific studies with a self-reported LOE improved significantly (from 81% to 93%, P=0.001). Compared with JPO, JBJS had a significantly higher rate of level I (12% vs. 3%, P=0.006) and a significantly lower rate of level III (23% vs. 34%, P=0.01) articles. From 2009 to 2013, 3% of articles in JPO were level I. Significantly more articles are now including a level of evidence designation. Approximately half of published studies are level IV, and most are therapeutic type. A higher percentage of level I studies were published in JBJS during the same time

    Full Text Available Introduction. We explored how ethnicity affects the risk of postoperative nausea and vomiting (PONV and established the correlation of suggested risk factors of PONV in the multiethnic population of Singapore. Methods. 785 patients who underwent orthopaedic surgery were recruited. These comprised 619 Chinese (78.9%, 76 Malay (9.7%, 68 Indian (8.7%, and 22 other (2.8% cases. The presence of possible risk factors of PONV and nausea and/or vomiting within 24 h after surgery was studied. Univariate and multivariate logistic regression analyses were performed. Results. The incidence of PONV was 33.2% (261 patients. There was no statistically significant difference of PONV incidence between Chinese, Malay, and Indian cases (34.6% versus 34.2% versus 29.4%, p=0.695. Indian females younger than 50 years were found to have a higher incidence of vomiting (p=0.02. The significant risk factors for this population include females, use of nitrous oxide, and a history of PONV. Conclusion. In the groups studied, ethnicity is not a significant risk factor for PONV except for young Indian females who have a higher risk of postoperative vomiting. We suggest the selective usage of antiemetic for young Indian females as prophylaxis and avoiding nitrous oxide use in high-risk patients.

    Pediatric orthopaedic fellowship applicants commonly use online-based resources for information on potential programs. Two primary sources are the San Francisco Match (SF Match) database and the Pediatric Orthopaedic Society of North America (POSNA) database. We sought to determine the accessibility and quality of information that could be obtained by using these 2 sources. The online databases of the SF Match and POSNA were reviewed to determine the availability of embedded program links or external links for the included programs. If not available in the SF Match or POSNA data, Web sites for listed programs were located with a Google search. All identified Web sites were analyzed for accessibility, content volume, and content quality. At the time of online review, 50 programs, offering 68 positions, were listed in the SF Match database. Although 46 programs had links included with their information, 36 (72%) of them simply listed http://www.sfmatch.org as their unique Web site. Ten programs (20%) had external links listed, but only 2 (4%) linked directly to the fellowship web page. The POSNA database does not list any links to the 47 programs it lists, which offer 70 positions. On the basis of a Google search of the 50 programs listed in the SF Match database, web pages were found for 35. Of programs with independent web pages, all had a description of the program and 26 (74%) described their application process. Twenty-nine (83%) listed research requirements, 22 (63%) described the rotation schedule, and 12 (34%) discussed the on-call expectations. A contact telephone number and/or email address was provided by 97% of programs. Twenty (57%) listed both the coordinator and fellowship director, 9 (26%) listed the coordinator only, 5 (14%) listed the fellowship director only, and 1 (3%) had no contact information given. The SF Match and POSNA databases provide few direct links to fellowship Web sites, and individual program Web sites either do not exist or do not

    Full Text Available BACKGROUND: There are always efforts to find a better and safer local anaesthetic along with adjuvants in epidural anaesthesia. Bupivacaine is a long acting , effective local anaesthetic that is commonly administered in anaesthesia practice. Despite its undoubted efficacy, bupivacaine is associated with cardiotoxicity and neurotoxicity. Central nervous system (CNS and cardiovascular adverse reactions reported after inadvertent intravascular or intravenous regional anesthesia have been linked to R (+ isomer of bupivacaine. So Levobupivacaine, the pure S ( - – enantiomer of racemic bupivacaine, was developed as an alternative to bupivacaine. Levobupivacaine is increasingly used in the clinical practice because of its safer pharmacological profile and faster protein binding rate AIM: This study was conducted to evaluate the onset and duration of analgesia, extent and duration of sensory and motor block, sedation and side effects of Dexmedetomidine and Clonidine when used as adjuvants to Levobupivacaine in epidural anaesthesia for lower limb orthopaedic surgeries. MATERIALS AND METHODS: A prospective randomized study was carried out in the department of Anaesthesia at Rajarajeswari Medical College and Hospital which included 50 adult patients between the ages of 21 and 60 years (o f ASA I/II grade who underwent lower limb orthopaedic surgeries. The patients were randomly allocated into two groups; levobupivacaine + dexmedetomidine (LD and levobupivacaine + clonidine (LC, comprising of 25 patients each. Group LD was administered 18 ml of 0.5% epidural levobupivacaine and 1.5 μg/kg of dexmedetomidine, while group LC received admixture of 18 ml of 0.5% levobupivacaine and 2 μg/kg of Clonidine . Onset of analgesia, sensory and motor block levels, sedation, duration of analgesia and side effects were observed. STATISTICAL ANALYSIS: The data obtained was subjected to statistical analysis using analysis of variance, student t test, chi - square test

    To examine the association between disease activity in early rheumatoid arthritis (RA), functional limitation and long-term orthopaedic episodes. Health Assessment Questionnaire (HAQ) disability scores were collected from two longitudinal early RA inception cohorts in routine care; Early Rheumatoid Arthritis Study and Early Rheumatoid Arthritis Network from 1986 to 2012. The incidence of major and intermediate orthopaedic surgical episodes over 25 years was collected from national data sets. Disease activity was categorised by mean disease activity score (DAS28) annually between years 1 and 5; remission (RDAS≤2.6), low (LDAS>2.6-3.2), low-moderate (LMDAS≥3.2-4.19), high-moderate (HMDAS 4.2-5.1) and high (HDAS>5.1). Data from 2045 patients were analysed. Patients in RDAS showed no HAQ progression over 5 years, whereas there was a significant relationship between rising DAS28 category and HAQ at 1 year, and the rate of HAQ progression between years 1 and 5. During 27 986 person-years follow-up, 392 intermediate and 591 major surgeries were observed. Compared with the RDAS category, there was a significantly increased cumulative incidence of intermediate surgery in HDAS (OR 2.59 CI 1.49 to 4.52) and HMDAS (OR 1.8 CI 1.05 to 3.11) categories, and for major surgery in HDAS (OR 2.48 CI 1.5 to 4.11), HMDAS (OR 2.16 CI 1.32 to 3.52) and LMDAS (OR 2.07 CI 1.28 to 3.33) categories. There was no significant difference in HAQ progression or orthopaedic episodes between RDAS and LDAS categories. There is an association between disease activity and both poor function and long-term orthopaedic episodes. This illustrates the far from benign consequences of persistent moderate disease activity, and supports European League Against Rheumatism treat to target recommendations to secure low disease activity or remission in all patients.

    2008-06-01

    Musculoskeletal research has brought about revolutionary changes in our ability to perform high precision surgery in joint replacement procedures. Recent advances in computer assisted surgery as well better materials have lead to reduced wear and greatly enhanced the quality of life of patients. The new surgical techniques to reduce the size of the incision and damage to underlying structures have been the primary advance toward this goal. These new techniques are known as MIS or Minimally Invasive Surgery. Total hip and knee Arthoplasties are at all time high reaching 1.2 million surgeries per year in the USA. Primary joint failures are usually due to osteoarthristis, rheumatoid arthritis, osteocronis and other inflammatory arthritis conditions. The methods for THR and TKA are critical to initial stability and longevity of the prostheses. This research aims at understanding the fundamental mechanics of the joint Arthoplasty and providing an insight into current challenges in patient specific fitting, fixing, and stability. Both experimental and analytical work will be presented. We will examine Cementless total hip arthroplasty success in the last 10 years and how computer assisted navigation is playing in the follow up studies. Cementless total hip arthroplasty attains permanent fixation by the ingrowth of bone into a porous coated surface. Loosening of an ingrown total hip arthroplasty occurs as a result of osteolysis of the periprosthetic bone and degradation of the bone prosthetic interface. The osteolytic process occurs as a result of polyethylene wear particles produced by the metal polyethylene articulation of the prosthesis. The total hip arthroplasty is a congruent joint and the submicron wear particles produced are phagocytized by macrophages initiating an inflammatory cascade. This cascade produces cytokines ultimately implicated in osteolysis. Resulting bone loss both on the acetabular and femoral sides eventually leads to component instability. As

    Full Text Available BACKGROUND: The impact of postoperative delirium on post-discharge functional status of older patients remains unclear, and little is known regarding the interrelationship between cognitive impairment and post-operative delirium. Therefore, the main purpose was to evaluate the post-discharge functional status of patients who experience delirium after undergoing orthopaedic surgery and the interrelationship of postoperative delirium with underlying cognitive impairment. METHOD: This prospective cohort study, conducted at a tertiary care medical center from April 2011 to March 2012, enrolled all subjects aged over 60 years who were admitted for orthopaedic surgery. The baseline characteristics (age, gender, BMI, and living arrangement, surgery-related factors (ASA class, admission type, type of surgery, and length of hospital stay, results of geriatric assessment (postoperative delirium, cognition, depressive mood, comorbidity, pain, malnutrition, polypharmacy, ADL, and instrumental [I]ADL and 1-12-month postoperative ADL and IADL functional status were collected for analysis. RESULTS: Overall, 9.1% of 232 patients (mean age: 74.7 ± 7.8 years experienced postoperative delirium, which was significantly associated with IADL decline at only 6 and 12 months postoperatively (RR: 6.22, 95% CI: 1.08-35.70 and RR: 12.54, 95% CI: 1.88-83.71, respectively. Delirium superimposed on cognitive impairment was a significant predictor for poor functional status at 6 and 12 months postoperatively (RR: 12.80, 95% CI: 1.65-99.40 for ADL at the 6th month, and RR: 7.96, 95% CI: 1.35-46.99 at the 12th month; RR: 13.68, 95% CI: 1.94-96.55 for IADL at the 6th month, and RR: 30.61, 95% CI: 2.94-318.54 at the 12th month, respectively. CONCLUSION: Postoperative delirium is predictive of IADL decline in older patients undergoing orthopaedic surgery, and delirium superimposed on cognitive impairment is an independent risk factor for deterioration of ADL and IADL functional

We studied effects of the intrathecal use of low dose clonidine with 0.5% hyperbaric bupivacaine on duration of analgesia and hemodynamic parameters. METHOD: This prospective study done on 60 patients belonging to ASA 1 or 2, undergoing orthopedic surgeries of lower limb under subarachnoid block were randomized into two groups(30 patients each, group 1 received saline and group 2 received 30 µg clonidine as adjuvant along with 2.5 ml of 0.5% hyperbaric bupivacaine intrathecal injection. During study, the duration and onset of sensory and motor block, duration of analgesia, and total requirement of rescue analgesics along with hemodynamic changes and side effects of study drugs were recorded. RESULTS: we found time delay in onset of both sensory and motor block in clonidine group which was statistically insignificant, and significant prolongation of both sensory (140.26 minutes Vs. 93.63 minutes and motor blockade (153.74 minutes Vs. 104.79 minutes p-value <0.001. CONCLUSION: Adjuvant use of low dose clonidine (30 µg with hyperbaric bupivacaine prolongs the duration of both sensory and motor blockade, and duration of analgesia without much hemodynamic adverse effects.

    Full Text Available OBJECTIVE: Pulmonary embolism (PE is an important complication of major orthopedic surgery. The aim of this study was to evaluate the incidence of venous thromboembolism (VTE and factors influencing the development of VTE in patients undergoing major orthopedic surgery in a university hospital. METHODS: Patients who underwent major orthopedic surgery (hip arthroplasty, knee arthroplasty, or femur fracture repair between February of 2006 and June of 2012 were retrospectively included in the study. The incidences of PE and deep vein thrombosis (DVT were evaluated, as were the factors influencing their development, such as type of operation, age, and comorbidities. RESULTS: We reviewed the medical records of 1,306 patients. The proportions of knee arthroplasty, hip arthroplasty, and femur fracture repair were 63.4%, 29.9%, and 6.7%, respectively. The cumulative incidence of PE and DVT in patients undergoing major orthopedic surgery was 1.99% and 2.22%, respectively. Most of the patients presented with PE and DVT (61.5% and 72.4%, respectively within the first 72 h after surgery. Patients undergoing femur fracture repair, those aged ≥ 65 years, and bedridden patients were at a higher risk for developing VTE. CONCLUSIONS: Our results show that VTE was a significant complication of major orthopedic surgery, despite the use of thromboprophylaxis. Clinicians should be aware of VTE, especially during the perioperative period and in bedridden, elderly patients (≥ 65 years of age.

    Full Text Available BACKGROUND : Addition of α2 adrenergic agonists with local anaesthetics in bupivacaine spinal anaesthesia prolongs the duration of sensory and motor blockade and postoperative analgesia with minimal haemod ynamic alterations. AIM AND OBJECTIVES: To compare and evaluate the efficacy of intravenous dexmedetomidine and clonidine as premedication on subarachnoid blockade duration, postoperative analgesia, and sedation score in patients undergoing lower limb orthopaedic surgeries in bupivacaine (0.5% heavy intrathecal block. MATERIALS AND METHOD S: We carried out a prospective, randomized, double blind study in which 60 patients of ASA status I or II, scheduled for orthopaedic lower limb surgery under spinal a naesthesia, were randomly allocated into two groups of 30 each group A and group B. Group A received dexmedetomidine 0.5μg/kg IV and group B received clonidine 1μg/kg in 10 ml of normal saline intravenously as premedication over 10 min., before subarachnoi d blockade with 3.0 ml. of 0.5% hyperbaric bupivacaine. Onset time and regression times of both sensory and motor blockade, haemodynamic parameters were recorded. Duration of postoperative analgesia and sedation score with adverse effects were also recorde d. RESULTS: The sensory block level was higher (T5 - T7 and earlier in onset (1.81±1.75min. in dexmedetomidine group than clonidine with level (T6 - T8 and onset (2.56±1.62min.. Dexmedetomidine also increased the onset (3.54±3.07min. and duration (265.45± 41.50min. of motor block achieved as compared to clonidine. The Ramsay sedation score was also greater in dexmedetomidine group than clonidine group (P<0.0001. CONCLUSION: Single dose of premedication with intravenous dexmedetomidine is better than intrav enous clonidine during bupivacaine spinal anaesthesia in orthopaedic lower limb surgeries for prolongation of sensory and motor blockade.

    The fusion of orthopaedic and trauma surgery into a combined specialty requires a new evaluation of postgraduate and undergraduate training. This study presents a structured analysis of the implementation possibilities for undergraduate training. After defining 3 implementation alternatives for both clinical training and last year electives, SWOT analyses were performed. RESULTS. The SWOT analysis demonstrates for each of these 6 implementation models the strengths, weaknesses, opportunities and threats. In order to strengthen undergraduate training in the “new” specialty all medical faculties should discuss and define their implementation concepts.

    Full Text Available Aim: To estimate the incidence of VTE in Indonesian patients undergoing major orthopedic surgery and not receiving thromboprophylaxis.Methods: This was an open clinical study of consecutive Indonesian patients undergoing major orthopedic surgery, conducted in 3 centers in Jakarta. Bilateral venography was performed between days 5 and 8 after surgery to detect the asymptomatic and to confi rm the symptomatic VTE. These patients were followed up to one month after surgery.Results: A total of 17 eligible patients were studied, which a median age of 69 years and 76.5% were females. Sixteen out of the 17 patients (94.1% underwent hip fracture surgery (HFS. The median time from injury to surgery was 23 days (range 2 to 197 days, the median duration of surgery was 90 minutes (range 60 to 255 minutes, and the median duration of immobilization was 3 days (range 1 to 44 days. Thirteen out of the 17 patients were willing to undergo contrast venography. A symptomatic VTE was found in 9 patients (69.2% at hospital discharge. Symptomatic VTE was found in 3 patients (23.1%, all corresponding to clinical signs of DVT and none with clinical sign of PE. These patients were treated initially with a low molecular weight heparin, followed by warfarin. Sudden death did not occur up to hospital discharge. From hospital discharge until 1-month follow-up, there were no additional cases of symptomatic VTE. No sudden death, bleeding complication, nor re-hospitalization was found in the present study.Conclusion: The incidence of asymptomatic (69.2% and symptomatic (23.1% VTE after major orthopedic surgery without thromboprophylaxis in Indonesian patients (SMART and AIDA, and still higher than the results of the Western studies. A larger study is required to establish the true incidence, and more importantly, that the use of thromboprophylaxis in these patients is warranted.

    Implants are an inevitable part of orthopaedic surgery. However, implant associated infection remains a major challenge for orthopaedic surgeons and researchers. This review focuses on current options available for prevention of implant associated infection, their drawbacks and future promising applications of nanotechnology-based approaches. Nanobiotechnology has shown remarkable progress in recent years especially in biomaterials, diagnostics, and drug delivery system. Although several applications of nanobiotechnology in orthopaedics have been described, few have elaborated their role in the prevention of implant related infection in orthopaedics. Novel "smart" drug delivery systems that release antibiotics locally in response to stimuli such as pH, temperature, enzymes or antigens; implant surface modification on a nanoscale to inhibit bacterial adhesion and propagation at the surgical site and biological approaches such as gene therapy to neutralize bacterial virulence and biomolecules to inhibit the quorum sensing adhesion of bacteria and disruption of biofilms can be used effectively to prevent orthopaedic implant related bacterial infection.

    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

    Dr. Michiharu Matsuoka studied orthopaedic surgery in Germany, Austria and other countries during the period from August, 1902 to May, 1906. He visited many university pathological institutes and surgical and orthopaedic clinics to study pathology and to learn the practice of orthopaedic surgery. After that, he started his practice at the newly established Department of Orthopaedic Surgery in the Medical School of Kyoto Imperial University in June, 1906. The department was opened in 1907 and in 1911 it was opened to all citizens and practical doctors in Kyoto City and exhibited many orthopaedic specimens and instruments. In particular, the x-ray apparatus of the Department was so well equipped that a German radiologist who visited the Department admired it in his article that was published in the journal of radiology in 1911. The Department was not surpassed by others for the number of patients with the dislocation of the hip and tuberculous spondylitis as well as the advanced quality and variety of roentgenological and pathological researches on these diseases.

    The objective of this study was to evaluate whether major abdominal surgery leads to complement activation and interleukin response and whether the kind of anaesthesia influence complement activation and the release of inflammatory interleukins. The study design was prospective and randomised. Fifty patients undergoing open major colorectal surgery due to cancer disease or inflammatory bowel disease were studied. Twenty-five patients were given total intravenous anaesthesia (TIVA) with propofol and remifentanil, and 25 patients were given inhalational anaesthesia with sevoflurane and fentanyl. To determine complement activation (C3a and SC5b-9) and the release of pro- and anti-inflammatory interleukins (tumour necrosis factor-a (TNF-a)), interleukin-1b (IL-1b), IL-6, IL-8, IL-4 and IL-10), blood samples were drawn preoperatively, 60 minutes after start of surgery, 30 minutes after end of surgery and 24 hours postoperatively. Complement was activated and pro-inflammatory interleukins (IL-6 and IL-8) and anti-inflammatory interleukins (IL-10) were released during major colorectal surgery. There was no significant difference between TIVA and inhalational anaesthesia regarding complement activation and cytokine release. Major colorectal surgery leads to activation of the complement cascade and the release of both pro-inflammatory and anti-inflammatory cytokines. There are no significant differences between total intravenous anaesthesia (TIVA) with propofol and remifentanil and inhalational anaesthesia with sevoflurane and fentanyl regarding complement activation and the release of pro- and anti-inflammatory interleukins. © 2012 The Authors.

    We evaluated 374 consecutive patients from May 2013 to April 2014 who underwent major cardiac surgery. Each patient had an interview and a neurological clinical examination during the rehabilitation period. Patients with possible peripheral nervous system (PNS) complications underwent further electrodiagnostic tests. Among 374 patients undergoing major heart surgery (coronary artery bypass grafting, valvular heart surgery, ascending aortic aneurysm repair) 23 (6.1 %) developed 34 new PNS complications. We found four brachial plexopathies; four carpal tunnel syndromes; five critical illness neuropathies; three worsening of pre-existing neuropathies; two involvement of X, one of IX and one of XII cranial nerves; three peroneal (at knee), one saphenous, two median (at Struthers ligament), six ulnar (at elbow) mononeuropathies; two meralgia parestheticas. Diabetes is a strong risk factor for PNS complications (p = 0.002); we could not find any other relationship of PNS complications with clinical conditions, demographic data (gender, age) or type of surgical intervention. The mononeuropathies of right arms can be related to ipsilateral vein cannulation; position of body and stretching from chest wall retraction may be the cause of mononeuropathies of left arms (more frequent); the use of saphenous vein and position of the limbs may be the cause of mononeuropathies of the legs; surgical and anesthetical procedures can injure cranial nerves; respiratory failure and infection during the first days after surgery can cause critical illness neuropathies. Careful preoperative assessment and intraoperative management may reduce the risk of long-term PNS complications after cardiac surgery.

    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.

    Infections are the most common noncardiac complication after cardiac surgery, but their incidence across a broad range of operations, as well as the management factors that shape infection risk, remain unknown. This study sought to prospectively examine the frequency of post-operative infections and associated mortality, and modifiable management practices predictive of infections within 65 days from cardiac surgery. This study enrolled 5,158 patients and analyzed independently adjudicated infections using a competing risk model (with death as the competing event). Nearly 5% of patients experienced major infections. Baseline characteristics associated with increased infection risk included chronic lung disease (hazard ratio [HR]: 1.66; 95% confidence interval [CI]: 1.21 to 2.26), heart failure (HR: 1.47; 95% CI: 1.11 to 1.95), and longer surgery (HR: 1.31; 95% CI: 1.21 to 1.41). Practices associated with reduced infection risk included prophylaxis with second-generation cephalosporins (HR: 0.70; 95% CI: 0.52 to 0.94), whereas post-operative antibiotic duration >48 h (HR: 1.92; 95% CI: 1.28 to 2.88), stress hyperglycemia (HR: 1.32; 95% CI: 1.01 to 1.73); intubation time of 24 to 48 h (HR: 1.49; 95% CI: 1.04 to 2.14); and ventilation >48 h (HR: 2.45; 95% CI: 1.66 to 3.63) were associated with increased risk. HRs for infection were similar with either HR: 1.13; 95% CI: 1.07 to 1.20). Major infections substantially increased mortality (HR: 10.02; 95% CI: 6.12 to 16.39). Major infections dramatically affect survival and readmissions. Second-generation cephalosporins were strongly associated with reduced major infection risk, but optimal duration of antibiotic prophylaxis requires further study. Given practice variations, considerable opportunities exist for improving outcomes and preventing readmissions. (Management Practices and Risk of Infection Following Cardiac Surgery; NCT01089712).

    With the changing delivery of orthopaedic surgical care, there is a need to define the knowledge and competencies that are expected of an orthopaedist providing general and/or acute orthopaedic care. This article provides a proposal for the knowledge and competencies needed for an orthopaedist to practice general and/or acute care orthopaedic surgery. Using the modified Delphi method, the General Orthopaedic Competency Task Force consisting of stakeholders associated with general orthopaedic practice has proposed the core knowledge and competencies that should be maintained by orthopaedists who practice emergency and general orthopaedic surgery. For relevancy to clinical practice, 2 basic sets of competencies were established. The assessment competencies pertain to the general knowledge needed to evaluate, investigate, and determine an overall management plan. The management competencies are generally procedural in nature and are divided into 2 groups. For the Management 1 group, the orthopaedist should be competent to provide definitive care including assessment, investigation, initial or emergency care, operative or nonoperative care, and follow-up. For the Management 2 group, the orthopaedist should be competent to assess, investigate, and commence timely non-emergency or emergency care and then either transfer the patient to the appropriate subspecialist's care or provide definitive care based on the urgency of care, exceptional practice circumstance, or individual's higher training. This may include some higher-level procedures usually performed by a subspecialist, but are consistent with one's practice based on experience, practice environment, and/or specialty interest. These competencies are the first step in defining the practice of general orthopaedic surgery including acute orthopaedic care. Further validation and discussion among educators, general orthopaedic surgeons, and subspecialists will ensure that these are relevant to clinical practice. These

    The purpose of this study was to identify the clinical pediatric orthopaedic articles with at least 100 citations published in all orthopaedic journals and to examine their characteristics. All journals dedicated to orthopaedics and its subspecialties were selected from the Journal Citation Report 2001 under the subject category "orthopedics." Articles cited 100 times or more were identified using the database of the Science Citation Index Expanded (SCI-EXPANDED, 1900 to present). The articles were ranked in a comprehensive list. Two authors independently reviewed the full text of each article and applied the inclusion and exclusion criteria to the list of articles. The 2 lists were then compared. All disagreements were resolved by consensus with input from the senior author. The final list of pediatric orthopaedic articles was then compiled. There were a total of 49 journals under the search category "orthopedics." Five journals were excluded as they were non-English journals. The remaining 44 journals were screened for articles with at least 100 citations. A total of 135 clinical pediatric orthopaedic articles cited at least 100 times were included. The most cited article was cited 692 times. The mean number of citations per article was 159 (95% confidence interval, 145-173). All the articles were published between 1949 and 2001, with 1980 and 1989 producing the most citation classics (34). The majority (90) originated from the United States, followed by the United Kingdom (12) and Canada (11). Scoliosis/kyphosis was the most common topic with 26 papers. The second most common subject was hip disorders (24). Therapeutic studies were the most common study type (71). Ninety-seven papers were assigned a 4 for level of evidence. The list of citation classics in pediatric orthopaedic articles is useful for several reasons. It identifies important contributions to the field of pediatric orthopaedics and their originators; it facilitates the understanding and discourse

    The U.S. Centers for Medicare & Medicaid Services (CMS) recently released the Open Payments database (OPD) detailing payments from industry to physicians and teaching hospitals. We seek here to provide an overview of the data with a focus on the orthopaedic community. We analyzed payments in the OPD from August 1 to December 31, 2013. The OPD consists of three individual databases: General Payments, Research Payments, and Ownership. Physician identification number, physician specialty, payment type, and payment value were collected. Physicians assigned to multiple specialties were excluded. Comparisons were made between orthopaedic surgeons and the remainder of the top fifteen specialties by payment value. In all, 2,697,015 payments with physicians were recorded; 491,223 of these payments (18.2%) were made to physicians with multiple listed specialties and were excluded. Excluding these potentially misattributed payments did not have a significant impact on the trends identified, and $394.5 million in payments remained. Orthopaedic surgeons represented 3.4% of payments but 25.6% of value, and 13,347 orthopaedic surgeons (68.9% of all active orthopaedic surgeons) were listed in the OPD. Payments over $10,000 represented only 1.6% of payments to orthopaedic surgeons but 75.5% of value. The majority of these payments (56.1%) were royalties. The median payment value for orthopaedic surgeons listed in the OPD was $38.11, with two payments per surgeon; the median aggregated value was $132.56 per surgeon.

    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 posteroanterior configuration of both imaging systems. Thus, the operators need to pay more attention to managing radiation exposure, especially when using the O-arm system.

  18. Addressing the Global Burden of Trauma in Major Surgery

    Full Text Available Despite a technically perfect procedure, surgical stress can determine the success or failure of an operation. Surgical trauma is often referred to as the neglected step-child of global health in terms of patient numbers, mortality, morbidity and costs. A staggering 234 million major surgeries are performed every year, and depending upon country and institution, up to 4% of patients will die before leaving hospital, up to 15% will have serious post-operative morbidity, and 5 to 15% will be readmitted within 30 days. These percentages equate to around 1000 deaths and 4000 major complications every hour, and it has been estimated that 50% may be preventable. New frontline drugs are urgently required to make major surgery safer for the patient and more predictable for the surgeon. We review the basic physiology of the stress response from neuroendocrine to genomic systems, and discuss the paucity of clinical data supporting the use of statins, beta-adrenergic blockers and calcium channel blockers. Since cardiac-related complications are the most common, particularly in the elderly, a key strategy would be to improve ventricular-arterial coupling to safeguard the endothelium and maintain tissue oxygenation. Reduced O2 supply is associated with glycocalyx shedding, decreased endothelial barrier function, fluid leakage, inflammation and coagulopathy. A healthy endothelium may prevent these secondary hit complications, including possibly immunosuppression. Thus the four pillars of whole body resynchronization during surgical trauma, and targets for new therapies, are: 1 the CNS, 2 the heart, 3 arterial supply and venous return functions, and 4 the endothelium. This is termed the Central-Cardio-Vascular-Endothelium (CCVE coupling hypothesis. Since similar sterile injury cascades exist in critical illness, accidental trauma, hemorrhage, cardiac arrest, infection and burns, new drugs that improve CCVE coupling may find wide utility in civilian and

    Patients, surgeons, and staff are exposed to ionizing radiation in pediatric orthopaedic surgery from diagnostic studies and imaging associated with procedures. Estimating radiation dose to pediatric patients is based on complex algorithms and dose to surgeons and staff is based on dosimeter monitoring. Surgeons can decrease radiation exposure to patients with careful and thoughtful ordering of diagnostic studies and by minimizing exposure intraoperatively. Surgeon and staff radiation exposure can be minimized with educational programs, proper shielding and positioning intraoperatively, and prudent use of intraoperative imaging. Overall, better awareness among pediatric orthopaedic surgeons of our role in radiation exposure can lead to improvements in radiation safety.

    Continuous invasive arterial blood pressure (IBP) monitoring remains the gold standard for BP measurement, but traditional oscillometric non-invasive intermittent pressure (NIBP) measurement is used in most low-to-moderate risk procedures. This study compared non-invasive continuous arterial BP measurement using a Nexfin® monitor with NIBP and IBP monitors. This was a single-centre, prospective, pilot study in patients scheduled for elective orthopaedic surgery. Systolic BP, diastolic BP and mean arterial blood pressure (MAP) were measured by Nexfin®, IBP and NIBP at five intraoperative time-points. Pearson correlation coefficients, Bland-Altman plots and trending ability of Nexfin® measurements were used as criteria for success in the investigation of measurement reliability. A total of 20 patients were enrolled in the study. For MAP, there was a sufficient correlation between IBP/Nexfin® (Pearson = 0.75), which was better than the correlation between IBP/NIBP (Pearson = 0.70). Bland-Altman analysis of the data showed that compared with IBP, there was a higher percentage error for MAPNIBP (30%) compared with MAPNexfin® (27%). Nexfin® and NIBP underestimated systolic BP; NIBP also underestimated diastolic BP and MAP. Trending ability for MAPNexfin® and MAPNIBP were comparable to IBP. Non-invasive BP measurement with Nexfin® was comparable with IBP and tended to be more precise than NIBP. © The Author(s) 2016.

    This study explored whether patients' preference for particular types of anaesthesia could be influenced pre-operatively by giving them the addresses of various relevant websites. Patients at an orthopaedic pre-assessment education clinic completed a questionnaire, which included a short multiple-choice general knowledge quiz about anaesthesia, and also questioned them as to their choice of anaesthesia (general or neuraxial). Patients were randomly assigned to intervention or control groups. Intervention group members were given the addresses of three relevant anaesthesia and health related websites to access at home. All patients were asked to complete the questionnaires on a second occasion, before surgery. Initially, most patients stated a preference for general anaesthesia. Subsequently, the intervention group altered their preference towards neuraxial anaesthesia compared to the control group (p 3.0 (11.0-14.0 [6.0-14.0])) than in the control group (from 10.0 (9.0-11.5 [3.0-13.0]) to 11.0 (9.0-12.0 [4.0-14.0]); p = 0.0068).

    The incidence of postoperative complications and death is low in the general population, but a subgroup of high-risk patients can be identified amongst whom adverse postoperative outcomes occur more frequently. The present study was undertaken to describe the incidence of postoperative complications, length of stay, and mortality after major abdominal surgery for gastrointestinal, hepatobiliary and pancreatic malignancies and to identify the risk factors for impaired outcome. Data of patients, operated on for gastro-intestinal malignancies during 2009-2010 were retrieved from the clinical database of Tartu University Hospital. Major outcome data included incidence of postoperative complications, hospital-, 30-day, 90-day and 1-year mortality, and length of ICU and hospital stay. High-risk patients were defined as patients with American Society of Anesthesiologists (ASA) physical status ≥3 and revised cardiac risk index (RCRI) ≥3. Multivariate analysis was used to determine the risk factors for postoperative mortality and morbidity. A total of 507 (259 men and 248 women, mean age 68.3±11.3 years) were operated on for gastrointestinal, hepatobiliary, or pancreatic malignancies during 2009 and 2010 in Tartu University Hospital, Department of Surgical Oncology. 25% of the patients were classified as high risk patients. The lengths of intensive care and hospital stay were 4.4±7 and 14.5±10 days, respectively. The rate of postoperative complications was 33.5% in the total cohort, and 44% in high-risk patients. The most common complication was delirium, which occurred in 12.8% of patients. For patients without high risk (ASA130min, and positive fluid balance >1300mL after the 1st postoperative day, were identified as independent risk factors for the development of complications. The complication rate after major gastro-intestinal surgery is high. ASA physical status and revised cardiac risk index adequately reflect increased risk for postoperative complications and

    Orthopaedic surgery has progressed over the years because of innovative work of pioneering orthopaedic surgeons; new developments in internal fixation techniques and implants codeveloped with the orthopaedic manufacturing industry have improved treatment greatly. This article analyzes and reviews the relationship of orthopaedic surgeons to the orthopaedic implant industry, analyzing three broad categories of the relationship: (1) physicians receiving gifts from industry; (2) the orthopaedic industry's financial support of educational and research endeavors of academic trauma and other centers; and (3) the relationship of the industry with innovators in the field of orthopaedic surgery by retainer fees, royalties, and stock options from industry. The ethical relationship requires: (1) putting the patient's concerns first above vested interests; (2) an awareness of a potential for abuse; and (3) a level of awareness of the relationship and the ability to explain and inculcate this relationship in the teaching program of young residents to maintain the high standards that have been set.

    Cancer patients are at increased risk for postoperative sepsis. However, studies addressing the issue are lacking. We sought to identify preoperative and intraoperative predictors of 30-d sepsis after major cancer surgery (MCS) and derive a postoperative sepsis risk stratification tool. Patients undergoing one of nine MCSs (gastrointestinal, urological, gynecologic, or pulmonary) were identified within the American College of Surgeons National Surgical Quality Improvement Program (2005-2011, n = 69,169). Multivariable adjusted analyses (MVA) were performed to identify the predictors of postoperative sepsis. A composite sepsis risk score (CSRS) was constructed using the regression coefficients of predictors significant on MVA. The score was stratified into low, intermediate, and high risk, and its predictive accuracy for sepsis, septic shock, and mortality was assessed using the area under the curve analysis. Overall, 4.3% (n = 2954) of patients developed postoperative sepsis. In MVA, Black race (odds ratio [OR] = 1.30, P = 0.002), preoperative hematocrit 3 (P sepsis. CSRS demonstrated favorable accuracy in predicting postoperative sepsis, septic shock, and mortality (area under the curve 0.72, 0.75, and 0.74, respectively). Furthermore, CSRS risk stratification demonstrated high concordance with sepsis rates, 1.3% in low-risk patients versus 9.7% in high-risk patients. Similarly, 30-d mortality rate varied from 0.5% to 5.5% (10-fold difference) in low-risk patients versus high-risk patients. Our study identifies the major risk factors for 30-d sepsis after MCS. These risk factors have been converted into a simple, accurate bedside sepsis risk score. This tool might facilitate improved patient-physician interaction regarding the risk of postoperative sepsis and septic shock. Copyright © 2016 Elsevier Inc. All rights reserved.

    There is dilemma as to whether patients infected with the Human Immunodeficiency Virus (HIV) requiring implant orthopaedic surgery are at an increased risk for post-operative surgical site infection (SSI). We conducted a systematic review to determine the effect of HIV on the risk of post-operative SSI and sought to determine if this risk is altered by antibiotic use beyond 24 hours. We searched electronic databases, manually searched citations from relevant articles, and reviewed conference proceedings. The risk of postoperative SSI was pooled using Mantel-Haenszel method. We identified 18 cohort studies with 16 mainly small studies, addressing the subject. The pooled risk ratio of infection in the HIV patients when compared to non-HIV patients was 1.8 (95% Confidence Interval [CI] 1.3-2.4), in studies in Africa this was 2.3 (95% CI 1.5-3.5). In a sensitivity analysis the risk ratio was reduced to 1.4 (95% CI 0.5-3.8). The risk ratio of infection in patients receiving prolonged antibiotics compared to patients receiving antibiotics for up to 24 hours was 0.7 (95% CI 0.1-4.2). The results may indicate an increased risk in HIV infected patients but these results are not robust and inconclusive after conducting the sensitivity analysis removing poor quality studies. There is need for larger good quality studies to provide conclusive evidence. To better develop surgical protocols, further studies should determine the effect of reduced CD4 counts, viral load suppression and prolonged antibiotics on the risk for infection.

    Full Text Available BACKGROUND Intrathecal anaesthesia and epidural anaesthesia are the most popular regional anaesthesia techniques used for lower limb surgeries. Intrathecal anaesthesia also called as subarachnoid block. It has few limitations like short duration of anaesthesia, extension of anaesthesia cannot be made for prolonged surgeries, rapid onset of sympathetic blockade, shorter duration of postoperative analgesia and troublesome complication of Post-Dural Puncture Headache (PDPH. Hence, epidural anaesthesia is the most preferred anaesthetic technique for lower limb surgeries these days. METHODS TIME FRAME The study was conducted during period spanning December 2013 to November 2014. STUDY POPULATION Patients who met all inclusion criteria were randomly selected. No distinction is made between males and females. STUDY DESIGN A prospective, randomised, double blind, case control, observational, interventional comparative study is designed after getting the informed written consent was obtained from the patient. RANDOMISATION Randomisation was done using a computer generated random number table. One hundred patients scheduled for various elective lower limb surgical procedures belonging to ASA class I and II were included in the study. 1.

    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.

    Two residents, wearing white coats with their names and "Department of Orthopaedics" conspicuously embroidered on them, boarded a hospital elevator crowded with physicians, employees, and visitors. In a clearly audible voice, one resident began a story: "You should have seen the patient I saw in my clinic the other day. She was beautiful. I should send her to see Dr. W. He would love to see her!" This comment drew the undivided attention of everyone in the elevator and cast a ghastly silence over the rest of the ride. In recent years, interest has expanded regarding professionalism and its importance in medicine and surgery. Orthopaedic surgery is no exception, as the topic has recently reached prominence in our literature and policies. It is unlikely that professionalism is a universal and innate characteristic of college students entering medical school, yet it becomes a necessary value in medical practice. Somewhere in the ongoing process of medical education, the issue must be addressed.

The present study explores the factors that contribute to the timing of elective surgery and patients' opinions on their quality of life as they wait for surgery.Methods: We followed adult patients with delayed elective surgical interventions (n=204. The causes for the delay and, particularly, the influence of blood shortage on the timing of the procedure were noted. Patients' perceptions on their quality of life as they waited for surgery were also noted.Results: We were able to establish a cause for delayed elective surgery in 133 patients. Shortage of operating space was the leading cause of surgery delay in 44 patients, while blood shortage followed closely in 40 patients. The higher the amount of blood ordered for use in the perioperative time, the longer the delay to surgery (P=0.001. Patients waiting for surgery had a low opinion of their in-hospital quality of life. Here, the key indicators included the threat of losing a job, limited family time, and an increase in day-to-day living costs.Conclusion: Blood shortage is the second most common cause of the delayed performance of elective surgical interventions in our institution.

    Limited research has been conducted on the non-medical out-of-pocket expenses (NOOPEs) incurred by families of children with chronic health conditions. The study objectives were to: 1) calculate the estimated NOOPEs incurred by families during hospitalization of their child, 2) identify predictors of high NOOPEs, and 3) assess the impact of the child's chronic health condition on the family's finances. Prospective observational study. Parents were included if their child was 3-20years old, had severe, non-ambulatory cerebral palsy (CP), and scheduled for hip or spine surgery. Parents reported all NOOPEs incurred during their child's hospitalization using the Family Expense Diary. Families completed the subscales of the Impact on Family Scale and the Assessment of Caregivers Experience with Neuromuscular Disease. Descriptive and univariate and multiple hierarchical regression models were used in the analysis. Fifty two parents participated. The total NOOPEs ranged from $193.00 to $7192.71 (M=$2001.92) per hospitalization representing an average of 4% of the family's annual earned income. Caregiver age (F=8.393, phospital (F=4.497, p=0.039) were significant predictors of high NOOPEs. The subscale scores indicated that a child's chronic health condition had a significant impact on family finances. Hospitalization is associated with numerous NOOPEs that create additional financial demands for families caring for a child with severe CP. NOOPEs should be addressed when preparing families for their children's planned hospital admissions, especially those families of CSHCN who experience significant financial impacts secondary to their children's care.

    In computer-assisted knee surgery, the accuracy of the localization of the femur centre of rotation relative to the hip-bone (hip joint centre) is affected by the unavoidable and untracked pelvic movements because only the femoral pose is acquired during passive pivoting manoeuvres. We present a dual unscented Kalman filter algorithm that allows the estimation of the hip joint centre also using as input the position of a pelvic reference point that can be acquired with a skin marker placed on the hip, without increasing the invasiveness of the surgical procedure. A comparative assessment of the algorithm was carried out using data provided by in vitro experiments mimicking in vivo surgical conditions. Soft tissue artefacts were simulated and superimposed onto the position of a pelvic landmark. Femoral pivoting made of a sequence of star-like quasi-planar movements followed by a circumduction was performed. The dual unscented Kalman filter method proved to be less sensitive to pelvic displacements, which were shown to be larger during the manoeuvres in which the femur was more adducted. Comparable accuracy between all the analysed methods resulted for hip joint centre displacements smaller than 1 mm (error: 2.2 ± [0.2; 0.3] mm, median ± [inter-quartile range 25%; inter-quartile range 75%]) and between 1 and 6 mm (error: 4.8 ± [0.5; 0.8] mm) during planar movements. When the hip joint centre displacement exceeded 6 mm, the dual unscented Kalman filter proved to be more accurate than the other methods by 30% during multi-planar movements (error: 5.2 ± [1.2; 1] mm).

Urban level 1 trauma center. Six hundred fourteen geriatric hip fracture patients from 2000 to 2009. Orthopaedic surgery for geriatric hip fracture. Patient demographics, medical comorbidities, hospitalization length, and admitting service. Negative binomial regression used to determine association between LOS and admitting service. 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 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 orthopaedic patients. This is the largest study to demonstrate that admission to the 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. Therapeutic Level III.

    Full Text Available Based on the development of digital medicine and digital anatomy, the concept of “digital orthopaedics” was raised by Pei Guo-Xian in China in 2006. The most striking feature of digital orthopaedics is the combination of basic and clinical orthopaedic knowledge with digital technology. In this review, we summarised the development of digital orthopaedics in China in recent years with respect to: the foundation of the Chinese Association of Digital Orthopedics, virtual human project (VHP, three-dimensional (3D reconstruction, finite element simulation, navigation in orthopaedic operations, and robot-assisted orthopaedic operations. In addition, we briefly reviewed digital orthopaedics in world leading institutes. We also looked into the future of digital orthopaedics in China and proposed the major challenges in digital technology and application in orthopaedics.

    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.

    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

    Much of the decision-making in orthopaedics rests on uncertain evidence. Uncertainty is therefore part of our normal daily practice, and yet physician uncertainty regarding treatment could diminish patients' health. It is not known if physician uncertainty is a function of the evidence alone or if other factors are involved. With added experience, uncertainty could be expected to diminish, but perhaps more influential are things like physician confidence, belief in the veracity of what is published, and even one's religious beliefs. In addition, it is plausible that the kind of practice a physician works in can affect the experience of uncertainty. Practicing physicians may not be immediately aware of these effects on how uncertainty is experienced in their clinical decision-making. We asked: (1) Does uncertainty and overconfidence bias decrease with years of practice? (2) What sociodemographic factors are independently associated with less recognition of uncertainty, in particular belief in God or other deity or deities, and how is atheism associated with recognition of uncertainty? (3) Do confidence bias (confidence that one's skill is greater than it actually is), degree of trust in the orthopaedic evidence, and degree of statistical sophistication correlate independently with recognition of uncertainty? We created a survey to establish an overall recognition of uncertainty score (four questions), trust in the orthopaedic evidence base (four questions), confidence bias (three questions), and statistical understanding (six questions). Seven hundred six members of the Science of Variation Group, a collaboration that aims to study variation in the definition and treatment of human illness, were approached to complete our survey. This group represents mainly orthopaedic surgeons specializing in trauma or hand and wrist surgery, practicing in Europe and North America, of whom the majority is involved in teaching. Approximately half of the group has more than 10 years

    Full Text Available Introduction: Contemporary literature indicates precaution over the perioperative use of non-steroidal anti-inflammatory drugs, since they can potentially increase perioperative blood loss related to their mechanism of action. The aim of this study was to assess the influence of non-steroidal anti-inflammatory drugs on perioperative blood loss undergoing hip arthroplasty and its correlation with general and regional anesthesia.Methods: This prospective study included 120 patients who had undergone elective unilateral total hip arthroplasty. Patients were allocated into four groups. Groups 1 and 2 were pretreated with diclofenac and operated in general and regional anesthesia. Group 3 and 4 weren’t pretreated with any non-steroidal anti-inflammatory drug and were, as well, operated in general and regional anesthesia. Diclofenac was administered orally two times a day 75 mg (total 150 mg and also as intramuscular injection (75 mg preoperatively and 12 hours later on a day of surgery.Results: The perioperative blood loss in the rst 24 hours showed an increase of 29.4% in the diclofenac group operated in general anesthesia and increase of 26.8% in patients operated in regional anesthesia (P < 0.05 compared to control group. Statistical data evaluation of patients operated in general anesthesia compared to regional anesthesia, the overall blood loss in the rst 24 h after surgery, showed an increase of 6.4% in the diclofenac group and increase of 3.6% in placebo group. This was not statistically significant.Conclusion: Pretreatment with non-steroidal anti-inflammatory drugs (diclofenac before elective unilateral total hip arthroplasty increases the perioperative blood loss signficantly. Early discontinuation of non-selective non-steroidal anti-inflammatory drugs is advised.

    2013-06-01

    The purpose of this review is to evaluate the influence of bariatric surgery on the use and pharmacokinetics of some frequently used drugs. A PubMed literature search was conducted. Literature was included on influence of bariatric surgery on pharmacoepidemiology and pharmacokinetics. Drug classes to be searched for were antidepressants, antidiabetics, statins, antihypertensive agents, corticosteroids, oral contraceptives, and thyroid drugs. A reduction in the use of medication by patients after bariatric surgery has been reported for various drug classes. Very few studies have been published on the influence of bariatric surgery on the pharmacokinetics of drugs. After bariatric surgery, theoretically, reduced drug absorption may occur. Correct dosing and choosing the right dosage form for drugs used by patients after bariatric surgery are necessary for optimal pharmacotherapy. Therefore, more clinical studies are needed on the influence of bariatric surgery on the pharmacokinetics of major drugs.

    not relieved sufficiently. Visual Analog Scale (VAS) was adopted to evaluate pain intensity at 1st (before injection), 2nd, 4th, 8th, 12th, 24th and 48th hour post-operatively. The dose of fentanyl citrate used, if added, was also recorded. Blood cell analysis, liver and kidney functions,ECG were performed before and one week after surgery. Any drug-related adverse event was observed. Results There were 105males (65. 63% ) and 55 females(34. 37 %) recruited in the study. The average age was 46. 36 years(21-65 years). Among them,85( 53. 1 %) received major surgery, 42(26. 3%) moderate surgery, 33(20. 6%) minor surgery. The average VAS score at one hour post-operation (before meloxicam injection) was 8. 3, and 7. 8, 7. 1, 6. 8, 5. 5, 3. 7, 2. 4 at other check points respectively.The VAS score was obviously reduced after the application of meloxicam injection, which indicates that meloxicam injection is effective in pain relief for most orthopeadic patients who had received surgery. VAS .scores recorded in 3 different groups divided by the invasive intensity of surgeries were compared to evaluate the efficacy of pain relief. It was showed that meloxicam injection was able to relieve pain in all groups, yet fentanyl citrate was needed in some cases who received moderate to major surgery. The lab results of blood cell analysis, liver and kidney functions and ECG showed no statistical difference before and after injection, which means meloxicam injection is safe for patients received orthpeadic surgeries. Conclusions Meloxicam injection is effident in pain relief after orthopaedic surgery. It reduces the usage and does of central analgesics and no obvious adverse events were observed during the study. In a word, it is an effective post-operative analgesic for orthopeadic patients.

    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.

    As lifestyle and diet patterns have become westernized in East Asia, the prevalence of obesity has rapidly increased. Bariatric surgeries, such as Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and laparoscopic adjustable gastric banding (LAGB), are considered the first-line treatment option in patients with severe obesity. However, postoperative complications have increased and the proper management of these complications, including the use of endoscopic procedures, has become important. The most serious complications, such as leaks and fistulas, can be treated with endoscopic stent placement and injection of fibrin glue, and a novel full-thickness closure over-the-scope clip (OTSC) has been used for treatment of postoperative leaks. Stricture at the gastrojejunal (GJ) anastomosis site after RYGB or incisura angularis in SG can be managed using stents or endoscopic balloon dilation. Dilation of the GJ anastomosis or gastric pouch may lead to failure of weight loss, and the use of endoscopic sclerotherapy, novel endoscopic suturing devices, and OTSCs have been attempted. Intragastric migration of the gastric band can be successfully treated using various endoscopic tools. Endoscopy plays a pivotal role in the management of post-bariatric complications, and close cooperation between endoscopists and bariatric surgeons may further increase the success rate of endoscopic procedures.

    In a clinical trial, 24 patients with haemophilia A who needed surgery or had suffered severe bleeding were treated by continuous infusion of Monoclate P, a factor VIII concentrate that is immunopurified by monoclonal antibodies. Continuous infusion of Monoclate P began with a dose of 2 U/kg per h that was adjusted according to the results of factor VIII assays to achieve a factor VIII target level of 100 IU/dl for 2 days and then 80 IU/dl for 5 days. The safety, efficacy, and economics of this approach were assessed. No haemorrhagic episodes were observed. The continuous infusion was convenient and had the advantage of producing steady-state levels of factor VIII. With a single-compartment model, we found median factor VIII clearance values of 3.11 (range 1.79-7.78) x 10(3) litres/kg per h, elimination rates of 5.0-19.4 x 10(-2)/h and a median half-life of 9.9 h (range 4.8-20.0 h). Clearance and the elimination rate appeared to decline over the infusion period, as judged by the decreasing infusion rate required to maintain the target concentration of factor VIII. An economic comparison with bolus therapy, using theoretically derived bolus dosages, indicated that the potential saving was related inversely to the factor VIII half-life. Potential savings of 75% were predicted on the first postoperative day, averaging 35% over the full course of therapy.

    AIM: To investigate the effects of an enteral supplement containing antioxidants on circulating levels of antioxidants and indicators of oxidative stress after major gastrointestinal surgery.METHODS: Twenty-one patients undergoing major upper gastrointestinal tract surgery were randomised in a single centre, open label study on the effect of postoperative enteral nutrition supplemented with antioxidants. The effect on circulating levels of antioxidants and indicators of oxidative stress, such as F2-isoprostane, was studied.RESULTS: The antioxidant enteral supplement showed no adverse effects and was well tolerated. After surgery a decrease in the circulating levels of antioxidant parameters was observed. Only selenium and glutamine levels were restored to pre-operative values one week after surgery. F2-isoprostane increased in the first three postoperative days only in the antioxidant supplemented group. Lipopolysaccharide binding protein (LBP) levels decreased faster in the antioxidant group after surgery.CONCLUSION: Despite lower antioxidant levelsthere was no increase in the circulating markers of oxidative stress on the first day after major abdominal surgery. The rise in F2-isoprostane in patients receiving the antioxidant supplement may be related to the conversion of antioxidants to oxidants which raises questions on antioxidant supplementation. Module AOX restored the postoperative decrease in selenium levels.The rapid decrease in LBP levels in the antioxidant group suggests a possible protective effect on gut wall integrity. Further studies are needed on the role of oxidative stress on outcome and the use of antioxidants in patients undergoing major abdominal surgery.

    The purpose of this investigation was to characterize the clinical efficacy and cost-effectiveness of simulation training aimed at reducing cast-saw injuries. Third-year orthopaedic residents underwent simulation-based instruction on distal radial fracture reduction, casting, and cast removal using an oscillating saw. The analysis compared incidences of cast-saw injuries and associated costs before and after the implementation of the simulation curriculum. Actual and potential costs associated with cast-saw injuries included wound care, extra clinical visits, and potential total payment (indemnity and expense payments). Curriculum costs were calculated through time-derived, activity-based accounting methods. The researchers compared the costs of cast-saw injuries and the simulation curriculum to determine overall savings and return on investment. In the 2.5 years prior to simulation, cast-saw injuries occurred in approximately 4.3 per 100 casts cut by orthopaedic residents. For the 2.5-year period post-simulation, the injury rate decreased significantly to approximately 0.7 per 100 casts cut (p = 0.002). The total cost to implement the casting simulation was $2,465.31 per 6-month resident rotation. On the basis of historical data related to cast-saw burns (n = 6), total payments ranged from $2,995 to $25,000 per claim. The anticipated savings from averted cast-saw injuries and associated medicolegal payments in the 2.5 years post-simulation was $27,131, representing an 11-to-1 return on investment. Simulation-based training for orthopaedic surgical residents was effective in reducing cast-saw injuries and had a high theoretical return on investment. These results support further investment in simulation-based training as cost-effective means of improving patient safety and clinical outcomes. Therapeutic Level III.

    Full Text Available Background: mortality predicting models in cardiac surgery have been created based on certain population groups. It would be important to know their effectiveness in patients who underwent surgery with no extracorporeal circulation and cardioplegic cardiac arrest. Objective: To determine risk factors to predict mortality and major complications in revascularized patients with no use of extracorporeal circulation and to analyze the behaviour of two stratification models of preoperative risk in cardiac surgery. Methods: A prospective observational study conducted from January 2007 to December 2008 at the Cardiology Center of Santa Clara. The sample included 136 patients who underwent coronary artery bypass grafting with no extracorporeal circulation. Variables collected prospectively were the basis to identify. Risk scales Parsonnet and EuroSCORE 97 were calculated for each patient. Their capacity to predict mortality and possible complications was analyzed through ROC curves. Results: Preoperative variables that significantly increased death risk and major complications were: history of chronic obstructive pulmonary disease, history of diabetes mellitus and three vessel coronary artery disease. Conclusions: Parsonnet and Euroscore 97 risk scales are accurate for mortality and major complications prediction in beating heart revascularization.

    Delirium can be caused by haemodynamics abnormalities during anaesthesia. The main role in delirium appearance is given to decreasing of cerebral perfusion pressure. Especially it can happen in patients with underlying intracranial hypertension. Anaesthetics effects on intracranial pressure are different therefore cerebral hypoperfusion can happens in these patients even without systemic hypotension. Purpose of the study was to define an effect of cerebral perfusion pressure decreasing during different technics of anaesthesia on frequency of delirium in elderly patients after major abdominal surgery. The article deals with results of study of 182 patients (medium age 69 y.o.) underwent elective major abdominal surgery. Delirium frequency was 11%, continuing of delirium was 3 days. The frequency of delirium was higher in patients who had got anaesthesia based on sevoflurane. Additionally these patients had higher frequency of cerebral perfusion pressure decreasing. Conclusions; Anaesthesia based on sevoflurane is characterized by higher frequency of postoperative delirium in elderly patients after major abdominal surgery.

    To analyse whether mitochondrial DNA (mtDNA) haplogroups are associated with severe sepsis and mortality after major surgery. We performed a case-control study on 240 cardiac or abdominal surgery patients developing severe sepsis (Case-group) and 267 cardiac or abdominal surgery patients without severe sepsis and with systemic inflammatory response syndrome (SIRS, Control-group). Furthermore, a longitudinal substudy was performed for analysing the survival in septic patients. Only European white patients within the N macro-cluster were included. Case-group underwent cardiac surgery had lower frequencies of cluster HV (p = 0.005) and haplogroup H (p = 0.005) and higher frequencies of cluster JT (p = 0.028) than Control-group; but no significant differences were found for abdominal surgery. Besides, both cluster HV and haplogroup H were associated with decreased odds of severe sepsis (adjusted odds ratio (aOR) = 0.45 (95%CI = 0.25; 0.82); p = 0.009 and aOR = 0.48 (95%CI = 0.26; 0.87); p = 0.015, respectively) among patients underwent cardiac surgery. In Case-group, 45.4% (109/240) patients died with a survival median of 39 (95%CI = 31.4; 46.62) days. When the clusters were examined, 41% (55/134) patients within cluster HV died versus 71.4% (10/14) patients within cluster IWX (p = 0.018). Additionally, patients within cluster IWX had an increased risk of death (adjusted hazard ratio (aHR) = 2.22; (95%CI = 1.14; 4.34); p = 0.019). European mitochondrial haplogroups might be related to the onset of severe sepsis in patients who underwent major cardiac surgery, but not in patients underwent major abdominal surgery. Besides, mtDNA haplogroups could have influence on mortality in septic patients. Copyright © 2014 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

    Patient safety has become a central and measurable key factor in the routine daily medical practice. The human factor plays a decisive role in safety culture and has moved into focus regarding the reduction of treatment errors and undesired critical incidents. Nonetheless, the systematic training in communication and interpersonal competences has so far only played a minor role. The German Society of Orthopaedics and Trauma (DGOU) in cooperation with the Lufthansa Aviation Training initiated a course system for interpersonal competence. Several studies confirmed the reduction of critical incidents and costs after implementation of a regular and targeted human factor training. The interpersonal competence should be an essential component of specialist training within the framework of a 3‑column model.

  14. The future of orthopaedics in the United States: an analysis of the effects of managed care in the face of an excess supply of orthopaedic surgeons.

    Clark, R; Thurston, N K

    2000-03-01

    Recent technological advances in orthopaedic surgery have propelled both the volume of surgical cases and their complexity, resulting in increased costs, which should naturally result in higher incomes for surgeons. However, the transition from a fee-for-service model of physician compensation to a managed care model has resulted in major shifts in economic resource allocation. An economic model of this market based on imperfect competition shows that these changes have shifted market power from surgeons to the managed care organizations. Our model predicts that practicing surgeons will retire earlier, medical students will begin to select other specialties, and innovation will be slowed. Antitrust laws limit surgeons' ability to combat this trend through meaningful collective bargaining, creating the potential for future shortages as the baby boom generation reaches retirement age and the demand for orthopaedic services increases dramatically.

    To evaluate the effect of intraoperative dexmedetomidine (DEX) infusion during propofol intravenous anesthesia on postoperative recovery after major spinal surgery. Sixty patients aged 18 to 65 (American Society of Anesthesiologists, ASA I-II), scheduled for spinal surgery from January 2014 to May 2014 were randomized into two groups. The DEX group (n=30) received 0.5 μg/kg of DEX ten minutes before anesthesic induction, followed by an infusion of DEX at 0.2 μg/(kg×h) intraoperatively and the control group (n=30) was given identical amounts of normal saline. At the end of surgery, the patients of both groups received patient-controlled intravenous analgesia (PCIA) with morphine 0.5 mg/h (1 mg demand dose and 8 min lockout). Heart rate and mean arterial pressure (MAP) were continually monitored during operation and in the post-anesthesia care unit (PACU). The propofol and sufentanil consumptions during operation and the morphine consumption 48 h after surgery were recorded. The time for recovery and extubation were recorded. The followed-up evaluations were performed to assess Ramsay scores, visual analogue scale (VAS) pain scores as well as side effects in PACU and 48 h after surgery. Heart rate of DEX group was lower than that of control group after intubation and extubation and in PACU 10 min (Panesthesic induction, the sufentanil consumption during operation and the cumulative consumption of morphine 2 h and 6 h after surgery were decreased (P<0.05). There were no differences between the two groups as to the time for recovery or extubation. Compared with control group, the VAS pain scores were significantly decreased (P<0.01), the incidence of postoperative nausea and vomiting in DEX group were significantly decreased (P<0.05) 48 h after surgery. Intraoperative infusion of DEX improved quality of recovery, provided good analgesia, and decreased morphine use and the incidence of postoperative nausea and vomiting after major spinal surgery.

    Since 1963, the Orthopaedic In-Training Examination (OITE) has been administered to orthopedic residents to assess residents' knowledge and measure the quality of teaching within individual programs. The OITE currently consists of 275 questions divided among 12 domains. This study analyzed all OITE basic science questions between 2006 and 2010. The following data were recorded: number of questions, question taxonomy, category of question, type of imaging modality, and recommended journal and book references. Between 2006 and 2010, the basic science section constituted 12.2% of the OITE. The assessment of taxonomy classification showed that recall-type questions were the most common, at 81.4%. Imaging modalities typically involved questions on radiographs and constituted 6.2% of the OITE basic science section. The majority of questions were basic science questions (eg, genetics, cell replication, and bone metabolism), with an average of 26.4 questions per year. The Journal of Bone & Joint Surgery (American Volume) and the American Academy of Orthopaedic Surgeons' Orthopaedic Basic Science were the most commonly and consistently cited journal and review book, respectively. This study provides the first review of the question content and recommended references of the OITE basic science section. This information will provide orthopedic trainees, orthopedic residency programs, and the American Academy of Orthopaedic Surgeons Evaluation Committee valuable information related to improving residents' knowledge and performance and optimizing basic science educational curricula.

  5. Stereoscopy in orthopaedics

    Tan, S. L. E.

    2005-03-01

    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.

    Enhanced recovery after surgery (ERAS) programs have been introduced increasingly into major visceral surgery. Key elements target on early drain removal and mobilization of the patients; however, reporting of adherence to ERAS protocols has often been insufficiently assessed. The present study aims to prospectively evaluate ERAS compliance after major visceral surgery. A prospective pilot study was designed, and 34 patients scheduled for major hepatopancreatic or gastric surgery were followed postoperatively until postoperative day (POD) 10. Analgesia and drain management, diet, mobilization, willingness to exercise, and the use of discharge criteria were accurately assessed within an established ERAS protocol scenario. Thirty-one cases were analyzed that consisted of 54.8 % major pancreatic, 29.0 % hepatic, and 16.1 % gastric resections. The median hospital stay was 12.5 days, and 83.9 % of the patients met the objective criteria before discharge. By POD 4, wound, epidural, and urinary catheters were still in place in 70, 60, and 40 % of the patients, respectively. Fifty percent of the patients ambulated out of bed until POD 2. The cumulative duration of postoperative mobilization per day ranged from 15 to 155 min, and only 40 % of the patients felt comfortable with additional mobilization or physical exercise. Adherence to ERAS protocols is poorly reported. The results indicate a discrepancy between ERAS targets and actual practice in comorbid patients undergoing major visceral surgery, need for a prompt redefinition of ERAS mobilization targets, need for the improvement of counseling, and need for the implementation of ERAS principles.

    Trimethylamine-N-oxide (TMAO) is formed in the liver from trimethylamine (TMA), a product exclusively generated by the gut microbiota from dietary phosphatidylcholine and carnitine. An alternative pathway of TMAO formation from carnitine is via the microbiota-dependent intermediate γ-butyrobetaine (γBB). Elevated TMAO levels are associated with cardiovascular disease (CVD), but little is known about TMAO in obesity. Given the proposed contribution of microbiota alterations in obesity and type 2 diabetes (T2D), we investigated the potential impact of obesity, lifestyle-induced weight loss, and bariatric surgery on plasma levels of TMAO, its microbiota-dependent intermediate γBB, and its diet-dependent precursors carnitine and choline. TMAO, γBB, carnitine, and choline were measured by high-performance liquid chromatography in 34 obese individuals (17 with and 17 without T2D) undergoing bariatric surgery and 17 controls. TMAO was not elevated in obese patients or reduced by lifestyle interventions but increased approximately twofold after bariatric surgery. Similar to TMAO, plasma levels of γBB were not influenced by lifestyle interventions but increased moderately after bariatric surgery. In contrast, carnitine and choline, which are abundant in nutrients, such as in red meat and eggs, and not microbiota dependent, were reduced after lifestyle interventions and rebounded after bariatric surgery. The major increase in TMAO after bariatric surgery was unexpected because high TMAO levels have been linked to CVD, whereas bariatric surgery is known to reduce CVD risk. Prospective studies of gut microbiota composition and related metabolites in relation to long-term cardiovascular risk after bariatric surgery are warranted.

    Full Text Available Early identification of patients at risk for delirium is important, since adequate well timed interventions could prevent occurrence of delirium and related detrimental outcomes. The aim of this study is to evaluate prognostic factors for delirium, including factors describing frailty, in elderly patients undergoing major surgery.We included patients of 65 years and older, who underwent elective surgery from March 2013 to November 2014. Patients had surgery for Abdominal Aortic Aneurysm (AAA or colorectal cancer. Delirium was scored prospectively using the Delirium Observation Screening Scale. Pre- and peri-operative predictors of delirium were analyzed using regression analysis. Outcomes after delirium included adverse events, length of hospital stay, discharge destination and mortality.We included 232 patients. 51 (22% underwent surgery for AAA and 181 (78% for colorectal cancer. Postoperative delirium occurred in 35 patients (15%. Predictors of postoperative delirium included: delirium in medical history (Odds Ratio 12 [95% Confidence Interval 2.7-50], advancing age (Odds Ratio 2.0 [95% Confidence Interval 1.1-3.8] per 10 years, and ASA-score ≥3 (Odds Ratio 2.6 [95% Confidence Interval 1.1-5.9]. Occurrence of delirium was related to an increase in adverse events, length of hospital stay and mortality.Postoperative delirium is a frequent complication after major surgery in elderly patients and is related to an increase in adverse events, length of hospital stay, and mortality. A delirium in the medical history, advanced age, and ASA-score may assist in defining patients at increased risk for delirium. Further attention to prevention of delirium is essential in elderly patients undergoing major surgery.

    At the beginning of the 1930s, various factors made it necessary to transform one of the institutions which was renowned for its work regarding the social reinsertion of the disabled, that is, the Instituto de Reeducación Profesional de Inválidos del Trabajo (Institute for Occupational Retraining of Invalids of Work). The economic crisis of 1929 and the legislative reform aimed at regulating occupational accidents highlighted the failings of this institution to fulfill its objectives. After a time of uncertainty, the centre was renamed the Instituto Nacional de Reeducación de Inválidos (National Institute for Retraining of Invalids). This was done to take advantage of its work in championing the recovery of all people with disabilities.This work aims to study the role played in this process by the poliomyelitis epidemics in Spain at this time. It aims to highlight how this disease justified the need to continue the work of a group of professionals and how it helped to reorient the previous programme to re-educate the "invalids." Thus we shall see the way in which, from 1930 to 1950, a specific medical technology helped to consolidate an "individual model" of disability and how a certain cultural stereotype of those affected developed as a result. Lastly, this work discusses the way in which all this took place in the midst of a process of professional development of orthopaedic surgeons.

    Full Text Available Abstract We describe an unusual case of osteosarcoma in a Jehovah's Witness patient who underwent chemotherapy and major surgery without the need for blood transfusion. This 16-year-old girl presented with osteosarcoma of the right proximal tibia requiring proximal tibia resection, followed by endoprosthesis replacement. She was successfully treated with neoadjuvant chemotherapy and surgery with the support of haematinics, granulocyte colony-stimulating factor, recombinant erythropoietin and intraoperative normovolaemic haemodilution. This case illustrates the importance of maintaining effective, open communication and exploring acceptable therapeutic alternative in the management of these patients, whilst still respecting their beliefs.

    To review the success and morbidity of laparoscopic major gynecologic surgery in patients with prior laparotomy bowel resection. Review of a prospective surgical database of all cases of laparoscopic major gynecologic surgery in patients with prior laparotomy bowel resection. No cases were excluded. Bowel diagnoses and procedures were total colectomy for inflammatory bowel disease (4), partial colectomy for colon cancer (6), partial small bowel resection for obstruction (1), and Whipple for pancreatic cancer (2). Two patients had 3 prior laparotomies, 8 patients had 2 prior laparotomies, and 3 patients had 1 prior laparotomy. All prior abdominal incisions were midline. Gynecologic diagnoses and procedures were laparoscopic cytoreduction for ovarian cancer (1), lsh/bso/staging for ovarian cancer (1), lavh/bso/lymphadenectomy for endometrial cancer (4), and lavh/bso, lsh/bso, or bso for large ovarian mass (7). Median patient age was 57 years, median BMI was 31kg/m(2), and all patients had medical comorbidities. All 13 laparoscopic gynecologic surgeries were successful without trocar insertion injury, conversion to laparotomy, and without enterotomy. Abdominal adhesions were present in all cases. Median operative time was 2 hours, median blood loss was 100cc, and median hospital stay was 1 day. There were no postoperative complications. Laparoscopic major gynecologic surgery in patients with prior laparotomy bowel resection is feasible for experienced laparoscopic surgeons.

    Metabolic acidosis is frequently observed in perioperative patients, especially those who undergo major surgery. The aim of this study was to evaluate the factors related to post-operative metabolic acidosis and to attempt to identify the clinical effect of metabolic acidosis following major abdominal surgery. We included 172 patients admitted to a surgical intensive care unit (ICU) following major abdominal surgery. All cases were divided into either the acidosis or the normal group using immediate post-operative standard base excess (SBE). The following clinical data were retrospectively obtained from the chart and ICU database: basic clinical characteristics, operative data, type and volume of fluid infused during the operation, post-operative arterial blood gas analysis, lactate, and central venous oxygen saturation. The predominant intraoperative fluid was either 0.9% saline or lactated Ringer's solution. The operation length, estimated blood loss, total fluid infused, total saline infused, lactate and corrected chloride were significantly higher in the acidosis group; however, central venous oxygen saturation was lower in the normal group. Among these factors, total infused saline and lactate level were independent factors related to metabolic acidosis. The comparison between the types of fluid revealed that the saline group had a significantly lower SBE, strong ion difference and higher corrected chloride. SBE was significantly correlated with lactate and total infused saline. ICU and hospital length of stay were significantly longer in the acidosis group. Post-operative metabolic acidosis following major abdominal surgery was closely related to both hyperchloremic acidosis associated with large saline infusion and lactic acidosis caused by lactataemia. © 2012 The Authors.

    Glycosylated hemoglobin (HbA1c) is diagnostic of and a measure of the quality of control of diabetes mellitus. Both HbA1c and perioperative hyperglycemia have been targeted as modifiable risk factors for postoperative complications. The HbA1c percent cutoff that best predicts major complications has not been defined. A prospective study of all abdominal operations from a single institution from 2007 to 2010 was performed. All patients with HbA1c within 3 months before surgery were included. The primary end point was major complication, using the Clavien-Dindo complication system, within 30 days of surgery. Stepwise, multivariate analysis was performed including clinically relevant variables chosen a priori. Among 438 patients who had a measured HbA1c, 96 (21.9%) experienced a major complication. On multivariate analysis, HbA1c ≥ 6.5% (odds ratio = 1.95; 95% CI, 1.17-3.24; p = 0.01) was found to be the most significant predictor of major complications. Glyosylated hemoglobin and glucose were strongly correlated (correlation coefficient 0.414, p 30 kg/m(2), history of coronary artery disease, and nonwhite race were more likely to have a HbA1c ≥ 6.5%. Elevated HbA1c ≥ 6.5% and perioperative hyperglycemia were associated with an increased rate of major complications after abdominal surgery. Elevated peak postoperative glucose levels were correlated with elevated HbA1c and were independently associated with major complications. More liberal HbA1c testing should be considered in high-risk patients before elective surgery. Safe, feasible, and effective strategies to reduce both HbA1c and perioperative hyperglycemia need to be developed to optimize patient outcomes. Copyright © 2015 American College of Surgeons.

    1995-01-01

    Major surgery as well as endotoxin-induced sepsis is accompanied by lymphocytopenia in peripheral blood. The purpose of this study was to investigate the redistribution of lymphocyte subpopulations and adhesion/activation molecules on lymphocytes. Twenty-four rats were included in the investigation....... Eight rats received an intraperitoneal injection of E. coli endotoxin (2 mg kg-1), eight rats had a sham operation performed while eight rats received isotonic saline and served as a control group.

    Background: A substantial number of orthopaedic surgeons apply for sports medicine fellowships after residency completion. The Internet is one of the most important resources applicants use to obtain information about fellowship programs, with the program website serving as one of the most influential sources. The American Orthopaedic Society for Sports Medicine (AOSSM), San Francisco Match (SFM), and Arthroscopy Association of North America (AANA) maintain databases of orthopaedic sports medicine fellowship programs. A 2013 study evaluated the content and accessibility of the websites for accredited orthopaedic sports medicine fellowships. Purpose: To reassess these websites based on the same parameters and compare the results with those of the study published in 2013 to determine whether any improvement has been made in fellowship website content or accessibility. Study Design: Cross-sectional study. Methods: We reviewed all existing websites for the 95 accredited orthopaedic sports medicine fellowships included in the AOSSM, SFM, and AANA databases. Accessibility of the websites was determined by performing a Google search for each program. A total of 89 sports fellowship websites were evaluated for overall content. Websites for the remaining 6 programs could not be identified, so they were not included in content assessment. Results: Of the 95 accredited sports medicine fellowships, 49 (52%) provided links in the AOSSM database, 89 (94%) in the SFM database, and 24 (25%) in the AANA database. Of the 89 websites, 89 (100%) provided a description of the program, 62 (70%) provided selection process information, and 40 (45%) provided a link to the SFM website. Two searches through Google were able to identify links to 88% and 92% of all accredited programs. Conclusion: The majority of accredited orthopaedic sports medicine fellowship programs fail to utilize the Internet to its full potential as a resource to provide applicants with detailed information about the

    While the neuroprotective benefits of estrogen and progesterone in critical illness are well established, the data regarding the effects of androgens are conflicting. Surgical repair of congenital heart disease is associated with significant morbidity and mortality, but there are scant data regarding the postoperative metabolism of sex steroids in this setting. The objective of this prospective observational study was to compare the postoperative sex steroid patterns in pediatric patients undergoing major cardiac surgery (MCS) versus those undergoing less intensive non-cardiac surgery. Urinary excretion rates of estrogen, progesterone, and androgen metabolites (μg/mmol creatinine/m(2) body surface area) were determined in 24-h urine samples before and after surgery using gas chromatography-mass spectrometry in 29 children undergoing scheduled MCS and in 17 control children undergoing conventional non-cardiac surgery. Eight of the MCS patients had Down's syndrome. There were no significant differences in age, weight, or sex between the groups. Seven patients from the MCS group showed multi-organ dysfunction after surgery. Before surgery, the median concentrations of 17β-estradiol, pregnanediol, 5α-dihydrotestosterone (DHT), and dehydroepiandrosterone (DHEA) were (control/MCS) 0.1/0.1 (NS), 12.4/11.3 (NS), 4.7/4.4 (NS), and 2.9/1.1 (p=0.02). Postoperatively, the median delta 17β-estradiol, delta pregnanediol, delta DHT, and delta DHEA were (control/MCS) 0.2/6.4 (p=0.0002), -3.2/23.4 (p=0.013), -0.6/3.7 (p=0.0004), and 0.5/4.2 (p=0.004). Postoperative changes did not differ according to sex. We conclude that MCS, but not less intensive non-cardiac surgery, induced a distinct postoperative increase in sex steroid levels. These findings suggest that sex steroids have a role in postoperative metabolism following MCS in prepubertal children.

    Full Text Available Abstract Meeting patients' nutritional requirements and preventing malnutrition is a challenge following major surgical procedures. The role of ghrelin in nutritional recovery after non-gastrointestinal major surgery is unknown. We used coronary artery bypass grafting (CABG as an example of anticipated good recovery post major surgery. Seventeen patients undergoing CABG (mean ± SEM: 70.1 ± 2.2 yrs, BMI 29.1 ± 1.4 kg/m2, 15 male underwent fasting and postprandial (45 mins after standard test breakfast blood sampling pre-operatively (day 0, post-operatively (day 6 and at follow-up (day 40. Changes in food intake, biochemical and anthropometric markers of nutritional status were recorded. A comparison was made to 17 matched healthy controls (70.6 ± 2.3 yrs, BMI 28.4 ± 1.3 kg/m2. We observed significantly increased post-operative and follow-up fasting ghrelin concentrations compared with pre-operatively (pre-op. 402 ± 42 pmol/L vs post-op. 642 ± 97 pmol/L vs follow-up 603 ± 94 pmol/L (ANOVA p p Our data support the hypothesis that prolonged changes in fasting and postprandial plasma ghrelin concentrations are associated with impaired nutritional recovery after CABG. These findings reinforce the need to investigate ghrelin in other patients groups undergoing major surgery.

    As a consumer-driven industry, cosmetic plastic surgery is subject to ebbs and flows as the economy changes. There have been many predictions about the short, intermediate, and long-term impact on cosmetic plastic surgery as a result of difficulties in the current economic climate, but no studies published in the literature have quantified a direct correlation. The authors investigate a possible correlation between cosmetic surgery volume and the economic trends of the three major US stock market indices. A volume analysis for the time period from January 1992 to October 2008 was performed (n = 7360 patients, n = 8205 procedures). Four cosmetic procedures-forehead lift (FL), rhytidectomy (Rh), breast augmentation (BA), and liposuction (Li)-were chosen; breast reduction (BRd), breast reconstruction (BRc), and carpal tunnel release (CTR) were selected for comparison. Case volumes for each procedure and fiscal quarter were compared to the trends of the S&P 500, Dow Jones (DOW), and NASDAQ (NASD) indices. Pearson correlation statistics were used to evaluate a relationship between the market index trends and surgical volume. P values correlation to all three major market indices. FL (n =312) only correlated to the NASD (P = .021) and did not reach significance with the S&P 500 (P = .077) or DOW (P = .14). BRd and BRc demonstrated a direct correlation to two of the three stock market indices, whereas CTR showed an inverse (ie, negative) correlation to two of the three indices. This study, to our knowledge, is the first to suggest a direct correlation of four cosmetic and two reconstructive plastic surgery procedures to the three major US stock market indices and further emphasizes the importance of a broad-based plastic surgery practice in times of economic recession.

    To assess the association of systemic inflammation and outcome after major abdominal surgery. Major abdominal surgery carries a high postoperative morbidity and mortality rate. Studies suggest that inflammation is associated with unfavorable outcome. Levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α and the systemic inflammatory response syndrome (SIRS) were assessed in 137 patients undergoing major abdominal surgery. Blood samples were drawn on days 0, 1, 3, and 7, and SIRS was scored during 48 hours after surgery. Primary outcome was a composite of mortality, pneumonia, sepsis, anastomotic dehiscence, wound infection, noncardiac respiratory failure, atrial fibrillation, congestive heart failure, myocardial infarction, and reoperation within 30 days of surgery. An IL-6 level more than 432 pg/mL on day 1 was associated with an increased risk of complications (adjusted odds ratio: 3.3; 95% confidence interval [CI]: 1.3-8.5) and a longer median length of hospital stay (7 vs 12 days, P < 0.001). As a single test, an IL-6 cut-off level of 432 pg/mL on day 1 yielded a specificity of 70% and a sensitivity of 64% for the prediction of complications (area under the curve: 0.67; 95% CI: 0.56-0.77). Levels of CRP started to discriminate from day 3 onward with a specificity of 87% and a sensitivity of 58% for a cut-off level of 203 mg/L (AUC: 0.73; 95% CI: 0.63-0.83). A high IL-6 level on day 1 is associated with postoperative complications. Levels of IL-6 help distinguish between patients at low and high risk for complications before changes in levels of CRP.

    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.

    Full Text Available BackgroundCoryneform species other than Corynebacterium diphtheriae are coming up as important pathogens with the potential to cause serious and life-threatening infections not only in immunocompromised but in immunocompetent individuals as well. The exact infectious potential of these bacteria and their rational antimicrobial treatment is a challenging but essential task.Method The study was conducted in the Department of Microbiology and the Department of Orthopaedics, JNMCH, AMU, Aligarh between August 2007 and May 2009. Pus samples were collected from patients of osteomyelitis and other bone infections including orthopaedic surgical site infections. The Corynebacterium species isolated in the study was identified using standard microbiological techniques and antimicrobial sensitivity testing was done by Kirby bauer disc diffusion method.ResultsA total of 312 Corynebacterium species were isolated. The majority of the coryneforms were isolated from the immunocompetent patients 270 (86.54%. C.jeikium was the most common coryneform isolated. Nearly half of the patients 153 (49.04% had acute infection caused by Corynebacterium species after orthopaedic surgery, a quarter 66 (21.15% had chronic infection and 72 (23.08% patients had device-related infection. Coryneforms exhibited maximum resistance to aminoglycosides (58.65% and β-lactams (penicillin group- 57.55%. C.jeikium was found to be the most resistant amongst all the Corynebacterium species.ConclusionThe study highlights the fact that the coryneforms are no longer just opportunistic pathogens but they are also becoming important pathogens among immunocompetent individuals as well. The emergence of drug resistance amongst these isolates is of most concern. More studies should be done on identification and on antimicrobial susceptibility of these organisms for the proper treatment of patients with such infections.

    Postoperative bleeding is common after cardiac surgery. Major bleeding (MB) is a determinant of red blood cell (RBC) transfusion, especially in patients with preoperative anemia. Preoperative anemia and RBC transfusions are recognized risk factors for operative mortality. The present study investigates the role of MB as an independent determinant of operative mortality in cardiac surgery. A single-center retrospective study based on the institutional database of cardiac surgery in the period 2000-2012 was conducted. Sixteen thousand one hundred fifty-four (16,154) consecutive adult patients undergoing cardiac surgery were analyzed. The impact of postoperative bleeding and MB on operative (30 days) mortality was analyzed univariately and after correction for preoperative anemia, RBC transfusions, and other confounders. Postoperative bleeding was significantly (p bleeding is per se a risk factor for operative mortality. However, its deleterious effects are strongly enhanced by RBC transfusions and, to a lesser extent, preoperative anemia. Major bleeding is a partially modifiable risk factor, and adequate preemptive and treatment strategies should be applied to limit this event. Copyright © 2013 The Society of Thoracic Surgeons.

    The call for evidence-based knowledge in clinical nursing practice has increased during recent decades and research in orthopaedic nursing is needed to improve patients' conditions, care and treatment. A descriptive cross-sectional survey was conducted to determine the self-perceived theoretical...... knowledge and practical research competencies among orthopaedic nurses and their interest and motivation to increase these in everyday practice. A newly developed questionnaire was given to a convenience sample of 87 orthopaedic nurses. Forty three orthopaedic nurses (49.4%) completed the questionnaire....... The results indicated that despite the majority of orthopaedic nurses having low self-perceived theoretical knowledge and practical research competencies, their interest and motivation to improve these were high, especially their inner motivation. However, the nurses' inner motivation was inhibited by a lack...

    Conclusion: Epidural, PCIA and opioid infusions are used for pain relief after major abdominal surgeries at our hospital. Although there is limited drug availability, regular assessments and appropriate dose adjustments by acute pain management service (APMS and use of multimodal analgesia led to a high level of patient satisfaction. We recommend that feedback to the primary anesthesiologists by APMS is of utmost importance to enable improvement in practice.

    Cardiovascular complications signify a major cause of morbidity and mortality in patients undergoing vascular surgery adversely affecting both short- and long-term prognosis. During the last decade, unmet needs for a distinct cardiovascular risk assessment have led to an intensive research for establishment of biomarkers with sufficient predictive value. This literature review aims in examining the value of several biomarkers in predicting the incidence of major adverse cardiac events in vascular surgery patients. We reviewed the English language literature and analyzed the biomarkers as independent predictors or in correlation with other factors. We found several biomarkers showing a significant predictive value for a major adverse cardiovascular event in patients undergoing vascular surgery. These biomarkers can be used in clinical practice as outcome predictors, although sensitivity and specificity varies. Detection of subclinical cardiovascular damage may improve total risk estimation and facilitate clinical assessment of patients at risk for future cardiovascular events. The wide variety of sensitivity and specificity in predicting a MACE of these biomarkers exert the need for future trials in which these markers will be tested as adjunctive tools of cardiovascular risk estimation scoring systems.

    The burden of readmissions after major cancer surgery is high. Prior work suggests that one-third of readmitted patients are readmitted to a different hospital than where the surgery was performed. The impact of this location of readmission needs to be more thoroughly understood. This retrospective cohort study was performed on Surveillance, Epidemiology, and End Results (SEER)-Medicare patients with bladder, esophagus, lung, or pancreas cancer diagnosed from 2001 to 2007 who underwent extirpative surgery and were readmitted within 90 days. Readmission location was classified as 'index' if readmission was at the hospital where surgery was performed, or 'different' if readmission was elsewhere. Outcomes including complications, reoperations, in-hospital mortality, 90-day mortality, and 90-day total costs were compared based on the location of readmission using a propensity score inverse probability treatment weight analysis. Overall, 7903 (28 %) patients were readmitted within 90 days of index hospitalization. Thirty-three percent were readmitted to a different hospital (bladder 30 %, esophagus 34 %, lung 34 %, pancreas 34 %). Ninety-day mortality and total costs of care were not significantly different between the readmission location groups (all p > 0.05); however, substantial differences in the types of patients, and timing of and reasons for readmission were observed between the two groups. Patients readmitted to different hospitals after major cancer surgery are a different group of patients than those readmitted to the index hospital. Accounting for this, we did not find significant differences in short-term clinical outcomes or costs of care based on readmission location; however, differences in long-term outcomes were observed that should be further explored in future studies.

    In the last 10 years, basic and clinical research in orthopaedics has developed rapidly. Understanding of orthopaedic disorders involves not only routine diagnosis, but also the pursuit of highly efficient and accurate three-dimensional imaging of the intra- and extra-medullary distribution, form and structure of orthopaedic disorders, thus allowing scientific evaluation of the indications for surgery, drawing up of the best surgical plan, minimization of operative trauma and the earliest possible restoration of limb function. Meanwhile, the most important type of basic research, which was previously biomechanical research, has gradually become computational biomechanics based on in vitro cadaver experiments. This review aims to summarize the research status and application prospects of digital technology in orthopaedics, including virtual reality technology, reverse engineering and rapid prototyping techniques, computational biomechanics, computer navigation technology and management of digitization of medical records. © 2012 Tianjin Hospital and Wiley Publishing Asia Pty Ltd.

    Full Text Available Background:Postoperative pain is an important surgical problem. Recent studies in pain pathophysiology have led to the hypothesis that with perioperative administration of analgesics (pre-emptive analgesia it may be possible to prevent or reduce postoperative pain. This study was planned to investigate the efficacy of pre-emptive analgesia on postoperative pain after major gynecologic abdominal surgeries. Methods: In this prospective, double-blinded, randomized, and placebocontrolled trial, 60 ASA physical status I and II patients undergoing major abdominal gynecologic surgeries were randomized to receive 45 mL of bupivacaine 0.375% or 45mL of normal saline; 30 mL and 15 mL of the treatment solution was administered into the peritoneal cavity and incision, respectively, before wound closure. The pain score of the patients was evaluated by the visual analogue scale (VAS on awakening, and at 6, 12, and 24h after surgery. Time to first analgesia request and total analgesic requirements in the first 24h were recorded. Results: Pain scores were significantly higher in the placebo group than in the bupivacaine group on awakening (5.98±1.01 v.s 1.05±1.05; p<0.001, and at 6h after surgery (5.37±0.85 vs. 2.51±1.02; p<0.001. First request to analgesia was significantly longer in the bupivacaine patients than in the placebo group (5.87±3.04 h vs.1.35±0.36; p<0.001.Meperidine consumption over 24h was 96.00 ±17.53 mg in the placebo group compared with 23.28 ±14.89 mg in the bupivacaine patients (p<0.001.Conclusion:A combination of intraperitoneal and incisional bupivacaine infiltration at the end of abdominal gynecologic surgeries reduces postoperative pain on awakening and for 6 hours after surgery, and provides significant opioidsparing analgesia for 24 h after gynecologic abdominal surgeries.

    To determine impact of obesity on recovery parameters and pulmonary functions of women undergoing major abdominal gynecological surgeries. Eighty women undergoing major gynecological surgeries were included in this study. Anesthesia was induced by remifentanil bolus, followed by propofol and cisatracurium to facilitate oro-tracheal intubation and was maintained by balanced anesthesia of remifentanil intravenous infusion and sevoflurane in oxygen and air. Time from discontinuation of maintenance anesthesia to fully awake were recorded at 1-min intervals and time from discontinuation of anesthesia until patient was transferred to post-anesthesia care unit (PACU) and discharged from PACU was also recorded. Pulmonary function tests were performed before surgery and repeated 4 h, days 1, 2 and 3 post-operative for evaluation of forced vital capacity, forced expiratory volume in 1 s and peak expiratory flow rate. Occurrence of post-operative complications, re-admission to ICU, hospital stay and morbidities were also recorded. Induction of anesthesia using remifentanil bolus injection resulted in significant decrease of heart rate and arterial pressures compared to pre-operative and pre-induction values. Recovery times were significantly shorter in obese compared to morbidly obese women. Post-operative pulmonary function tests showed significant deterioration compared to pre-operative measures but showed progressive improvement through first 3 post-operative days. Hospital stay was significantly shorter for obese compared to morbid obese women. Obesity delays recovery from general anesthesia, adversely affects pulmonary functions and increases post-operative complications. Remifentanil infusion and sevoflurane could be appropriate combination for obese and morbidly obese women undergoing major surgeries.

  17. Persistently High Hip Circumference after Bariatric Surgery Is a Major Hurdle to Successful Hip Replacement

    2014-01-01

    Full Text Available The prevalence of class III obesity (BMI≥40 kg/m2 in black women is 18%. As class III obesity leads to hip joint deterioration, black women frequently present for orthopedic care. Weight loss associated with bariatric surgery should lead to enhanced success of hip replacements. However, we present a case of a black woman who underwent Roux-en-Y gastric bypass with the expectation that weight loss would make her a better surgical candidate for hip replacement. Her gastric bypass was successful as her BMI declined from 52.0 kg/m2 to 33.7 kg/m2. However, her hip circumference after weight loss remained persistently high. Therefore, at surgery the soft tissue tunnel geometry presented major challenges. Tunnel depth and immobility of the soft tissue interfered with retractor placement, tissue reflection, and surgical access to the acetabulum. Therefore a traditional cup placement could not be achieved. Instead, a hemiarthroplasty was performed. After surgery her pain and reliance on external support decreased. But her functional independence never improved. This case demonstrates that a lower BMI after bariatric surgery may improve the metabolic profile and decrease anesthesia risk, but the success of total hip arthroplasties remains problematic if fat mass in the operative field (i.e., high hip circumference remains high.

    Evidence -based medicine (EBM) is designed to inform clinical decision-making within all medical specialties, including orthopaedic surgery. We recently published a pilot survey of the Canadian Orthopaedic Association (COA) membership and demonstrated that the adoption of EBM principles is variable among Canadian orthopaedic surgeons. The objective of this study was to conduct a broader international survey of orthopaedic surgeons to identify characteristics of research studies perceived as being most influential in informing clinical decision-making. A 29-question electronic survey was distributed to the readership of an established orthopaedic journal with international readership. The survey aimed to analyse the influence of both extrinsic (journal quality, investigator profiles, etc.) and intrinsic characteristics (study design, sample size, etc.) of research studies in relation to their influence on practice patterns. A total of 353 surgeons completed the survey. Surgeons achieved consensus on the 'importance' of three key designs on their practices: randomised controlled trials (94%), meta-analyses (75%) and systematic reviews (66%). The vast majority of respondents support the use of current evidence over historical clinical training; however subjective factors such as journal reputation (72%) and investigator profile (68%) continue to influence clinical decision-making strongly. Although intrinsic factors such as study design and sample size have some influence on clinical decision-making, surgeon respondents are equally influenced by extrinsic factors such as investigator reputation and perceived journal quality.Cite this article: Dr M.

    Objectives National and international evidence-based guidelines for hip and knee osteoarthritis (OA) recommend to start with non-surgical treatments, followed by surgical intervention if a patient does not respond sufficiently to non-surgical treatments, but there are indications that these are not optimally used. The aim of this study was to assess the extent to which all recommended non-surgical treatments were used by patients with hip or knee OA who receive(d) a total hip or knee replacement, as reported by patients and orthopaedic surgeons. Setting We performed two cross-sectional internet-based surveys among patients and orthopaedic surgeons throughout the Netherlands. Participants 195 OA patients either have undergone total knee arthroplasty or total hip arthroplasty no longer than 12 months ago or being on the waiting list for surgery with a confirmed date within 3 months and 482 orthopaedic surgeons were invited to participate. Primary and secondary outcome measures The use of recommended non-surgical treatments including education about OA/treatment options, lifestyle advice, dietary therapy, physical therapy, acetaminophen, NSAIDs and glucocorticoid injections. Results 174 OA patients (93%) and 172 orthopaedic surgeons (36%) completed the surveys. Most recommended non-surgical treatments were given to the majority of patients (eg, 80% education about OA, 73% physical therapy, 72% acetaminophen, 80% NSAIDs). However, only 6% of patients and 10% of orthopaedic surgeons reported using a combination of all recommended treatments. Dietary therapy was used least frequently. Only 11% of overweight and 30% of obese participants reported having received dietary therapy and 28% of orthopaedic surgeons reported to prescribe dietary therapy to overweight patients. Conclusions While most recommended non-surgical treatments were used frequently as single therapy, the combination is used in only a small percentage of OA patients. Especially, use of dietary therapy

    lowest category of orthopaedic surgery, this study has uncovered some initial gender differences regarding practice characteristics and job opportunities among pediatric orthopaedic surgeons. As more men plan to reduce their workload or retire in the next 5 years, there may be further increases in the percentage of women surgeons in the workforce, so it is important that we begin to understand what effect, if any, gender has on practice patterns, job selection, and opportunities. Also, the finding that among the new graduates more women than men are choosing careers in academic practice over private practice suggests an extraordinary opportunity to develop more female leaders and role models at major pediatric orthopaedic centers.

    Hemodynamically Unstable Pelvic Trauma is a major problem in blunt traumatic injury. No cosensus has been reached in literature on the optimal treatment of this condition. We present the results of the First Italian Consensus Conference on Pelvic Trauma which took place in Bergamo on April 13 2013. An extensive review of the literature has been undertaken by the Organizing Committee (OC) and forwarded to the Scientific Committee (SC) and the Panel (JP). Members of them were appointed by surgery, critical care, radiology, emergency medicine and orthopedics Italian and International societies: the Italian Society of Surgery, the Italian Association of Hospital Surgeons, the Multi-specialist Italian Society of Young Surgeons, the Italian Society of Emergency Surgery and Trauma, the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care, the Italian Society of Orthopaedics and Traumatology, the Italian Society of Emergency Medicine, the Italian Society of Medical Radiology, Section of Vascular and Interventional Radiology and the World Society of Emergency Surgery. From November 2012 to January 2013 the SC undertook the critical revision and prepared the presentation to the audience and the Panel on the day of the Conference. Then 3 recommendations were presented according to the 3 submitted questions. The Panel voted the recommendations after discussion and amendments with the audience. Later on a email debate took place until December 2013 to reach a unanimous consent. We present results on the 3 following questions: which hemodynamically unstable patient needs an extraperitoneal pelvic packing? Which hemodynamically unstable patient needs an external fixation? Which hemodynamically unstable patient needs emergent angiography? No longer angiography is considered the first therapeutic maneuver in such a patient. Preperitoneal pelvic packing and external fixation, preceded by pelvic binder have a pivotal role in the management of these patients

    Full Text Available Background. Malnutrition has serious implications for recovery after surgery. Early detection of malnutrition with nutritional support minimizes postoperative complications. Nutritional assessment tools need to be simple and suitable for use in everyday practice. In our study we wanted to determine, how many patients might benefit from nutritional support.Methods. From April to August 1999 fifty consecutively admitted patients predicted to major abdominal surgery have been examined. We used Mini nutritional assessment (MNA, Buzby’s nutrition risk index (NRI, blood albumin level and weight loss in the last 3 months period prior to the examination, to assess nutritional status.Results. We examined 50 patients (27 males and 23 females, age 76.5 ± 16.5 and confirmed malnutrition in 40% of patients with MNA and serum albumin level. The increased risk for nutrition-associated complications was confirmed by NRI and weight loss in 44%.Conclusions. A confident diagnosis of malnutrition and increased risk for nutrition-associated complications can be established by using a combination of simple methods like MNA, NRI, weight loss and serum albumin level. Almost half of the patients admitted for major abdominal surgery in General hospital Celje suffer from malnutrition and they may benefit with early nutritional intervention.

  4. Consolidating the medical model of disability: on poliomyelitis and the constitution of orthopedic surgery and orthopaedics as a speciality in Spain (1930-1950

    Martínez-Pérez, José

    2009-06-01

    Full Text Available At the beginning of the 1930s, various factors made it necessary to transform one of the institutions which was renowned for its work regarding the social reinsertion of the disabled, that is, the Instituto de Reeducación Profesional de Inválidos del Trabajo (Institute for Occupational Retraining of Invalids of Work. The economic crisis of 1929 and the legislative reform aimed at regulating occupational accidents highlighted the failings of this institution to fulfil its objectives. After a time of uncertainty, the centre was renamed the Instituto Nacional de Reeducación de Inválidos (National Institute for Retraining of Invalids. This was done to take advantage of its work in championing the recovery of all people with disabilities.

    This work aims to study the role played in this process by the poliomyelitis epidemics in Spain at this time. It aims to highlight how this disease justified the need to continue the work of a group of professionals and how it helped to reorient the previous programme to re-educate the «invalids». Thus we shall see the way in which, from 1930 to 1950, a specific medical technology helped to consolidate an «individual model» of disability and how a certain cultural stereotype of those affected developed as a result. Lastly, this work discusses the way in which all this took place in the midst of a process of professional development of orthopaedic surgeons.

    A comienzos de la década de 1930, una serie de factores obligaron a transformar una de las instituciones que más se había destacado en España en la labor de conseguir la reinserción social de las personas con discapacidades: el Instituto de Reeducación de Inválidos del Trabajo. La crisis económica de 1929 y las reformas legislativas destinadas a regular los accidentes del trabajo pusieron de relieve, entre otros factores, las limitaciones de esa institución para cumplir sus objetivos.

    2014-05-01

    Full Text Available Research in orthopaedic tissue engineering has intensified over the last decade and new protocols continue to emerge. The clinical translation of these new applications, however, remains associated with a number of obstacles. This report highlights the major issues that impede the clinical translation of advanced tissue engineering concepts, discusses strategies to overcome these barriers, and examines the need to increase incentives for translational strategies. The statements are based on presentations and discussions held at the AO Foundation-sponsored symposium "Where Science meets Clinics 2013" held at the Congress Center in Davos, Switzerland, in September, 2013. The event organisers convened a diverse group of over one hundred stakeholders involved in clinical translation of orthopaedic tissue engineering, including scientists, clinicians, healthcare industry professionals and regulatory agency representatives. A major point that emerged from the discussions was that there continues to be a critical need for early trans-disciplinary communication and collaboration in the development and execution of research approaches. Equally importantly was the need to address the shortage of sustained funding programs for multidisciplinary teams conducting translational research. Such detailed discussions between experts contribute towards the development of a roadmap to more successfully advance the clinical translation of novel tissue engineering concepts and ultimately improve patient care in orthopaedic and trauma surgery.

    2012-08-01

    With the introduction of the European Working Time Directive, surgical trainees are facing limited training opportunities and doctors are required to maximise their training opportunities. Smartphone sales have been rapidly increasing over the last five years and can be used as a training tool for the orthopaedic trainee and surgeon. Common uses include applications (AO, eLogbook and PubMed), Ebooks, online Logbooks, Guidelines and surgical techniques. In addition, smartphones can be used to immediately complete work-based assessments, in the absence of computers, hopefully increasing completion rates and reliability. Some journals now provide podcasts and video tutorials which may be accessed on smartphones, which is useful for higher examinations. Smartphones can also be used in the clinical setting to take photographs of wounds. Smartphones are enjoying increased uptake and application in the workplace and we review their use for orthopaedic surgeons and trainees to allow them to make the most out of their training opportunities.

    To recognize and document the small bowel reactions following major abdominal surgery is an important key for a correct diagnosis. Usually, plain abdominal radiography is the initial imaging examination requested in the immediate postoperative period, whereas gastrointestinal contrast studies are used to look for specific complications. In some countries, especially in Europe, sonography is widely employed to evaluate any acute affection of the abdomen. CT is commonly used to assess postoperative abdominal complications; in our institution also CT enteroclysis is often performed, to provide additional important informations. Radiologist should be able to diagnose less common types of obstruction, such as afferent loop, closed loop, strangulating obstruction as well as internal hernia. This knowledge may assume a critical importance for surgeons to decide on therapy. In this article, we focus our attention on the imaging (particularly CT) in small bowel complications following abdominal surgery.

  10. Feasibility of real-time location systems in monitoring recovery after major abdominal surgery.

    Early mobilization after major abdominal surgery decreases postoperative complications and length of stay, and has become a key component of enhanced recovery pathways. However, objective measures of patient movement after surgery are limited. Real-time location systems (RTLS), typically used for asset tracking, provide a novel approach to monitoring in-hospital patient activity. The current study investigates the feasibility of using RTLS to objectively track postoperative patient mobilization. The real-time location system employs a meshed network of infrared and RFID sensors and detectors that sample device locations every 3 s resulting in over 1 million data points per day. RTLS tracking was evaluated systematically in three phases: (1) sensitivity and specificity of the tracking device using simulated patient scenarios, (2) retrospective passive movement analysis of patient-linked equipment, and (3) prospective observational analysis of a patient-attached tracking device. RTLS tracking detected a simulated movement out of a room with sensitivity of 91% and specificity 100%. Specificity decreased to 75% if time out of room was less than 3 min. All RTLS-tagged patient-linked equipment was identified for 18 patients, but measurable patient movement associated with equipment was detected for only 2 patients (11%) with 1-8 out-of-room walks per day. Ten patients were prospectively monitored using RTLS badges following major abdominal surgery. Patient movement was recorded using patient diaries, direct observation, and an accelerometer. Sensitivity and specificity of RTLS patient tracking were both 100% in detecting out-of-room ambulation and correlated well with direct observation and patient-reported ambulation. Real-time location systems are a novel technology capable of objectively and accurately monitoring patient movement and provide an innovative approach to promoting early mobilization after surgery.

    The evolving influence of social media in trauma, acute, and critical care surgery (TACCS) cannot be ignored. We sought to investigate the extent and patterns of use of social networks by major regional, national and international TACCS societies. The two leading social networking sites, Facebook (FB) and Twitter (TW), were thoroughly examined for the presence of official accounts for each of the major TACCS societies. An official FB or TW account was defined as one which has a blue verified badge and/or is linked the society's official website. For societies with confirmed official accounts, the extent and patterns of use of the two platforms were systematically examined over a 2-week period through: (1) manual inspection of the societies' FB and TW pages, (2) the SQLite database containing downloaded samples of posts, and (3) the TW analytics database, symplur.com. Standardized social media metrics were calculated for each society. Posted content was categorized as being: (1) society news updates, (2) event announcements, or (3) general medical information. From a total of 64 TACCS societies, only 27 (42%) had FB and/or TW accounts. Ten out of the 12 American societies had accounts compared to 13/39 of European, 2/9 of Australasian, and 0/2 of international societies. For the societies with social media presence, the mean numbers of monthly tweets and FB posts per society were 22 and 8, respectively. We summarize the FB and TW activity of the studied TACCS societies. Most tweets/posts were society news updates and event announcements intended to the society's constituents not the general public. A text cloud was constructed to summarize the major featured topics. Less than half of the TACCS societies are currently using social media; those that do are arguably underutilizing its potential. Non-American societies in particular lag behind in their use of social networking.

    Full Text Available Morbidly obese patients with clinical features of obstructive sleep apnoea can present a myriad of challenges to the anaesthesiologists which must be addressed to minimise the perioperative risks. Initiation of continuous positive airway pressure (CPAP therapy early in the pre- and post-operative period along with appropriate anaesthetic planning is of paramount importance in such patients. This case report emphasises the usefulness of CPAP therapy, even for a short duration, to minimise morbidity, improve recovery and hasten early discharge from the hospital after major surgery.

    2007-01-01

    Full Text Available Abstract Recommendations for urgent reversal of oral anticoagulation with vitamin K1 antagonists are largely derived from case series employing empirical dosing regimens with vitamin K1 and prothrombin complex concentrates. Data on the use of prothrombin complex concentrates in this indication are scarce in the elderly who are at high risk of both hemorrhagic and thrombotic complications. The two cases presented here describe patients older than 75 years who underwent rapid International Normalized Ratio (INR reversal with prothrombin complex concentrates for surgical treatment of a bleeding ruptured spleen and for emergency surgery of a dissecting aorta. Both patients had their INRs rapidly corrected to ≤ 1.6 and underwent operation without complications. Evidence on treatment of patients who present with elevated INR and who have major bleeding or need to undergo emergency surgery is based mainly on observational studies. The two elderly patients presented here underwent successful emergency surgery after their INRs had been corrected with the intravenous use of vitamin K1 in combination with prothrombin complex concentrate that was administered according to current guideline recommendations.

    In Slovenia, orthopaedics started to develop at the end of WWI, when the number of the handicapped increased. Dr Anton Brecelj, who in 1919 laid the groundwork for the welfare of handicapped and sent a Czech doctor Franc Minař to specialise in orthopaedic surgery. When Minař returned to Ljubljana in 1923, he established an orthopaedic unit within surgery and in 1937 took over its management. Orthopaedics developed very quickly after 1945, when Ljubljana University set up a School of Medicine, a Department of Orthopaedics and Physical Medicine within the School, and Orthopaedic Clinic of the University Hospital. Orthopaedic surgeons from Ljubljana participated in the establishment of a hospital for osteoarticular tuberculosis in Valdoltra, (which later became the largest orthopaedic hospital in Slovenia), specialised clinics and orthopaedic hospital departments throughout Slovenia, schools for physiotherapists in Ljubljana, the Slovenian Rehabilitation Institute - Soča, the Home for Disabled Children in Kamnik, and the spa and rehabilitation centre in Laško. In 2011, orthopaedics in Slovenia holds 600 hospital beds and has about 75 orthopaedic surgeons who annually treat around 50,000 patients.

    Over the last 50 years, the commitment of orthopaedic surgeons to basic and clinical research and evaluation of treatment outcomes has made possible remarkable improvements in the care of people with injuries and diseases of the limbs and spine. A group of Oregon orthopaedic surgeons has had an important role in these advances, especially in the orthopaedic specialties of sports medicine and hip reconstruction. Since Don Slocum (Iowa Orthopaedic Resident, 1934-1937), started practice in Eugene, Oregon, in 1939, three orthopaedic surgeons, Denny Collis, Craig Mohler and Paul Watson, who received their orthopaedic residency education at the University of Iowa, and three orthopaedic surgeons, Stan James, Tom Wuest and Dan Fitzpatrick, who received their undergraduate, medical school and orthopaedic residency education at the University of Iowa, have joined the group Dr. Slocum founded. These individuals, and their partners, established and have maintained a successful growing practice that serves the people of the Willamette valley, but in addition, they have made important contributions to the advancement of orthopaedics.

    Despite the growing number of cancer cases and cancer surgeries around the world, the pharmacokinetics (PK) and pharmacodynamics (PD) of anesthetics used in this population are poorly understood. Patients operated due to cancer are usually in severe state and often require chemotherapy. It might affect the PK/PD of drugs used in this population. Therefore, in this study we explored the PK/PD of propofol in cancer patients having a major lung surgery. 23 patients that underwent a propofol-fentanyl total intravenous anesthesia were included in the analysis. A large set of demographic, biochemical and hemodynamic parameters was collected for the purpose of covariate analysis. Nonlinear mixed effect modeling in NONMEM was used to analyze the collected data. A three-compartment model was sufficient to describe PK of propofol. The anesthetic effect (AAI index) was linked to the propofol effect site concentrations through a sigmoidal E max model. A slightly higher value of clearance, a lower value of distribution clearance, and a decreased volume of peripheral compartment were observed in our patients, as compared with the literature values reported for healthy volunteers by Schnider et al. and by Eleveld et al. Despite these differences, both models led to a clinically insignificant bias of -8 and -1 % in concentration predictions, as reflected by the median performance error. The C e50 and propofol biophase concentration at the time of postoperative orientation were low and equaled 1.40 and 1.13 mg/L. The population PK/PD model was proposed for cancer patients undergoing a major lung surgery. The large body of studied covariates did not affect PK/PD of propofol significantly. The modification of propofol dosage in the group of patients under study is not necessary when TCI-guided administration of propofol by means of the Schnider model is used.

    Full Text Available CONTEXT AND OBJECTIVES: In major orthopedic surgery of the lower limbs, continuous spinal anesthesia (CSA and combined spinal epidural anesthesia (CSE are safe and reliable anesthesia methods. In this prospective randomized clinical study, the blockading properties and side effects of CSA were compared with single interspace CSE, among patients scheduled for major hip or knee surgery. DESIGN AND SETTING: Prospective clinical study conducted at the Institute for Regional Anesthesia, Hospital de Base, São José do Rio Preto. METHODS: 240 patients scheduled for hip arthroplasty, knee arthroplasty or femoral fracture treatment were randomly assigned to receive either CSA or CSE. Blockades were performed in the lateral position at the L3-L4 interspace. Puncture success, technical difficulties, paresthesia, highest level of sensory and motor blockade, need for complementary doses of local anesthetic, degree of technical difficulties, cardiocirculatory changes and postdural puncture headache (PDPH were recorded. At the end of the surgery, the catheter was removed and cerebrospinal fluid leakage was evaluated. RESULTS: Seven patients were excluded (three CSA and four CSE. There was significantly lower incidence of paresthesia in the CSE group. The resultant sensory blockade level was significantly higher with CSE. Complete motor blockade occurred in 110 CSA patients and in 109 CSE patients. Arterial hypotension was observed significantly more often in the CSE group. PDPH was observed in two patients of each group. CONCLUSION: Our results suggest that both CSA and CSE provided good surgical conditions with low incidence of complications. The sensory blockade level and hemodynamic changes were lower with CSA.

    This article describes the work of Dr. Antoni Marian Gabryszewski, orthopaedic surgeon, associate professor at Lvov University, towards the development of orthopaedics and rehabilitation in Poland before World War I. It is based on archival materials, publications in medical journals and articles from the daily press of that time. The author presents little-known facts concerning Dr. Gabryszewski's occupational and academic activity and his work at the Surgery Dept. of Lvov University as well as his habilitation dissertation, regarded as the first attempt to position orthopaedics as distinct from surgery in Poland. The article also describes his long-term work at the private Orthopaedic Facility established in 1898 in Lvov which later incorporated the Zander Institute in 1908. The Zander Institute was the first in Galicia to offer exercise machines designed by Dr. Gustav Zander, imported from Stockholm and enjoying an extraordinary popularity in the world. Dr. Gabryszewski's practice as a spa doctor, which he pursued in Iwonicz Zdrój in the summer months, is also presented. Dr. A. Gabryszewski introduced comprehensive rehabilitation to the treatment of orthopaedic patients both at the Surgery Dept. of Lvov University and at his Orthopaedic Facility. He used therapeutic gymnastics (particularly mechanotherapy), therapeutic massage, physical therapy and orthopaedic aids. Analysis of the source materials leads to unequivocal conclusions attesting to Dr. A. Gabryszewski's pioneering role and significant contribution to the development of orthopaedics and rehabilitation in Poland.

    Full Text Available Sebastian Werth, Kai Halbritter, Jan Beyer-WestendorfCenter for Vascular Medicine and Department of Medicine III, Division of Angiology, University Hospital “Carl Gustav Carus” Dresden, Dresden, GermanyAbstract: Over the last 15 years, low-molecular-weight heparins (LMWHs have been accepted as the “gold standard” for pharmaceutical thromboprophylaxis in patients at high risk of venous thromboembolism (VTE in most countries around the world. Patients undergoing major orthopedic surgery (MOS represent a population with high risk of VTE, which may remain asymptomatic or become symptomatic as deep vein thrombosis or pulmonary embolism. Numerous trials have investigated LMWH thromboprophylaxis in this population and demonstrated high efficacy and safety of these substances. However, LMWHs have a number of disadvantages, which limit the acceptance of patients and physicians, especially in prolonged prophylaxis up to 35 days after MOS. Consequently, new oral anticoagulants (NOACs were developed that are of synthetic origin and act as direct and very specific inhibitors of different factors in the coagulation cascade. The most developed NOACs are dabigatran, rivaroxaban, and apixaban, all of which are approved for thromboprophylaxis in MOS in a number of countries around the world. This review is focused on the pharmacological characteristics of apixaban in comparison with other NOACs, on the impact of NOAC on VTE prophylaxis in daily care, and on the management of specific situations such as bleeding complications during NOAC therapy.Keywords: major orthopedic surgery, apixaban, dabigatran, edoxaban, rivaroxaban, deep vein thrombosis, venous thromboembolism, VTE prophylaxis

    AIM:To investigate injuries of anatomy variants of hepatic duct confluence during hepatobiliary surgery and their impact on morbidity and mortality of these procedures. An algorithmic approach for the management of these injuries is proposed.METHODS: During a 6-year period 234 patients who had undergone major hepatobiliary surgery were retrospectively reviewed in order to study postoperative bile leakage. Diagnostic workup included endoscopic and magnetic retrograde cholangiopancreatography (E/MRCP), scintigraphy and fistulography.RESULTS: Thirty (12.8%) patients who developed postoperative bile leaks were identified. Endoscopic stenting and percutaneous drainage were successful in 23 patients with bile leaks from the liver cut surface.In the rest seven patients with injuries of hepatic duct confluence, biliary variations were recognized and a stepwise therapeutic approach was considered.Conservative management was successful only in 2 patients. Volume of the liver remnant and functional liver reserve as well as local sepsis were used as criteria for either resection of the corresponding liver segment or construction of a biliary-enteric anastomosis. Two deaths occurred in this group of patients with hepatic duct confluence variants (mortality rate 28.5%).CONCLUSION: Management of major biliary fistulae that are disconnected from the mainstream of the biliary tree and related to injury of variants of the hepatic duct confluence is extremely challenging. These patients have a grave prognosis and an early surgical procedure has to be considered.

    Microvascular free flaps are preferred for most major head and neck reconstruction surgeries because of better functional outcomes, improved esthetics, and generally higher success rates. Numerous studies have investigated measures to prevent flap loss, but few have evaluated the optimal treatment for free flap complications. This study aimed to determine the complication rate after free flap reconstructions and discusses our management strategies. Medical records of 260 consecutive patients who underwent free flap reconstructions for head and neck defects between July 2006 and June 2010 were retrospectively reviewed for patient and surgical characteristics and postoperative complications. The results revealed that microvascular free flaps were extremely reliable, with a 3.5 % incidence of flap failure. There were 78 surgical site complications. The most common complication was neck wound infection, followed by dehiscence, vascular congestion, abscess, flap necrosis, hematoma, osteoradionecrosis, and brisk bleeding. Twenty patients with poor wound healing received hyperbaric oxygen therapy, which was ineffective in three patients who eventually experienced complete flap loss. Eleven patients with vascular congestion underwent medicinal leech therapy, which was effective. Among the 78 patients with complications, 44 required repeat surgery, which was performed for postoperative brisk bleeding in three. Eventually, ten patients experienced partial flap loss and nine experienced complete flap loss, with the latter requiring subsequent pectoralis major flap reconstruction. Microvascular free flap reconstruction represents an essential and reliable technique for head and neck defects and allows surgeons to perform radical resection with satisfactory functional results and acceptable complication rates.

    To analyze the cumulative effect of risk factors associated with early major complications in postoperative spine surgery. Retrospective analysis of 583 surgically-treated patients. Early "major" complications were defined as those that may lead to permanent detrimental effects or require further significant intervention. A balanced risk score was built using multiple logistic regression. Ninety-two early major complications occurred in 76 patients (13%). Age > 60 years and surgery of three or more levels proved to be significant independent risk factors in the multivariate analysis. The balanced scoring system was defined as: 0 points (no risk factor), 2 points (1 factor) or 4 points (2 factors). The incidence of early major complications in each category was 7% (0 points), 15% (2 points) and 29% (4 points) respectively. This balanced scoring system, based on two risk factors, represents an important tool for both surgical indication and for patient counseling before surgery.

    Increased availability of medical information on the Internet empowers patients to look up answers to questions about their medical conditions. However, the quality of medical information available on the Internet is highly variable. Various tools for the assessment of online medical information have been developed and used to assess the quality and accuracy of medical web sites. In this study we used the LIDA tool (Minervation) to assess the quality of pediatric patient information on the AAOS (American Academy of Orthopaedic Surgeons) and POSNA (Pediatric Orthopaedic Society of North America) web sites. The accessibility, usability, and reliability of online medical information in the "Children" section of the AAOS web site and on the POSNA web site were assessed with use of the LIDA tool. Flesch-Kincaid (FK) and Flesch Reading Ease (FRE) values were also calculated to assess the readability of the pediatric education material. Patient education materials on each web site scored in the moderate range in assessments of accessibility, usability, and reliability. FK and FRE values indicated that the readability of each web site remained at a somewhat higher (more difficult) level than the recommended benchmark. The quality and readability of online information for children on the AAOS and POSNA web sites are acceptable but can be improved further. The quality of online pediatric orthopaedic patient education materials may affect communication with patients and their caregivers, and further investigation and modification of quality are needed.

    The US healthcare system is currently facing daunting demographic and economic challenges. Because musculoskeletal disorders and disease represent a substantial and growing portion of this healthcare burden, novel approaches will be needed to continue to provide high-quality, affordable, and accessible orthopaedic care to our population. The concept of "disruptive innovations," which has been studied and popularized by Harvard Business School Professor Clayton Christensen, may offer a potential framework for developing strategies to improve quality and control costs associated with musculoskeletal care. The introduction of mobile fluoroscopic imaging systems, the development of the Surgical Implant Generation Network intramedullary nail for treatment of long bone fractures in the developing world, the expanding role and contributions of physician assistants and nurse practitioners to the orthopaedic team, and the rise of ambulatory surgery centers are all examples of disruptive innovations in the field of orthopaedics. Although numerous cultural and regulatory barriers have limited the widespread adoption of these "disruptive innovations," we believe they represent an opportunity for clinicians to regain leadership in health care while at the same time improving quality and access to care for patients with musculoskeletal disease.

    Objectives: Ulnar collateral ligament reconstruction (UCLR) is a common procedure performed in Major League Baseball (MLB) pitchers with symptomatic UCL deficiencies. The purpose of this study was to determine: 1) the rate of return to pitching in the MLB following UCLR, 2) performance after return to pitching, and 3) the difference in return to pitching and performance between pitchers who underwent UCLR and matched controls who did not. Methods: MLB pitchers with symptomatic UCL deficiency that underwent UCLR between 1986 and 2012 were evaluated. Players' data was extracted from MLB team websites, injury reports, player profiles/biographies, press releases and cross-referenced with the MLB injury database (MLB411). All player, elbow, and surgical demographic data were analyzed. Age, body mass index (BMI), position, handedness, and MLB experience-matched controls were selected from the MLB during the same years as those undergoing UCLR. An "index year" was designated for controls, analogous to UCLR year in cases. Return to pitching and performance measures in MLB was compared between cases and controls. Student's t-tests were performed for analysis of within-group and between-group variables, respectively. Results: One hundred forty-eight pitchers (83%) were able to return to pitching in MLB. Length of career in MLB following UCLR was 3.9 +/- 2.84 years. Revision rate was 3.9%. In the year prior to UCLR (or index year in controls), cases were significantly (p<0.05) worse than controls with regard to number of innings pitched, games played, wins, and winning percentage and were not significantly different than controls in all remaining parameters. Pitchers undergoing UCLR had significantly (p<0.05) fewer losses, a lower losing percentage, and lower earned run average (ERA) following surgery (versus pre-surgery). In addition, cases threw significantly (p<0.05) fewer walks and allowed fewer hits, runs, and home runs following surgery. Comparisons between cases and

    Systemic inflammation participates to the complex healing process occurring after major surgery, thus directly affecting the surgical outcome and patient recovery. Total plasma N-glycome might be an indicator of inflammation after major surgery, as well as an anti-inflammatory therapy response marker, since protein glycosylation plays an essential role in the inflammatory cascade. Therefore, we assessed the effects of surgery on the total plasma N-glycome and the association with self-administration of postoperative morphine in two cohorts of patients that underwent major abdominal surgery. We found that plasma N-glycome undergoes significant changes one day after surgery and intensifies one day later, thus indicating a systemic physiological response. In particular, we observed the increase of bisialylated biantennary glycan, A2G2S[3,6]2, 12 hours after surgery, which progressively increased until 48 postoperative hours. Most changes occurred 24 hours after surgery with the decrease of most core-fucosylated biantennary structures, as well as the increase in sialylated tetraantennary and FA3G3S[3,3,3]3 structures. Moreover, we observed a progressive increase of sialylated triantennary and tetraantennary structures two days after surgery, with a concomitant decrease of the structures containing bisecting N-acetylglucosamine along with bi- and trisialylated triantennary glycans. We did not find any statistically significant association between morphine consumption and plasma N-glycome.

    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.

    Postoperative cognitive dysfunction (POCD) is a decline in cognitive function that occurs after surgery. The purpose of this study was to estimate the incidence and identify potential risk factors of POCD in older adults undergoing major noncardiac surgery. A total of 69 patients aged 65 years or older undergoing major noncardiac surgery were enrolled. Patients' cognitive function was assessed before and 3 months after surgery using a computerized neurocognitive battery. A nonsurgical control group of 54 older adults was recruited to adjust for learning effects from repeated administration of neurocognitive tests. Data about potential risk factors for POCD were collected before, during, and after surgery, including patient, medication, and surgery factors. The incidence of POCD was calculated using the Z-score method. A multivariable logistic regression model was used to identify risk factors for POCD. POCD was present in eleven patients (15.9%, 95% confidence interval [CI] = 7.3-24.6) 3 months after major noncardiac surgery. Carrying the apolipoprotein E4 (APOE4) genotype (odds ratio [OR] = 4.74, 95% CI = 1.09-22.19), using one or more highly anticholinergic or sedative-hypnotic drugs at home prior to surgery (OR = 5.64, 95% CI = 1.35-30.22), and receiving sevoflurane for anesthesia (OR = 6.43, 95% CI = 1.49-34.66) were associated with the development of POCD. POCD was observed in 15.9% of older adults after major noncardiac surgery. Risk factors for POCD in these patients were carrying the APOE4 genotype, using one or more highly anticholinergic or sedative-hypnotic drugs prior to surgery, and receiving sevoflurane for anesthesia.

    For patients exposed to a massive blood loss during surgery, maintained coagulation competence is important. It is less obvious whether coagulation competence influences bleeding during elective surgery where patients are exposed to infusion of a crystalloid or a colloid. This randomized controlled trial evaluates whether administration of 5% human albumin (HA) or lactated Ringer solution (LR) affects coagulation competence and in turn blood loss during cystectomy due to bladder cancer. Forty patients undergoing radical cystectomy were included to receive either 5% HA (n = 20) or LR (n = 20). Nineteen patients were analyzed in the HA group and 20 patients in the lactated Ringer group. Blinded determination of the blood loss was similar in the 2 groups of patients: 1658 (800-3300) mL with the use of HA and 1472 (700-4330) mL in the lactated Ringer group (P = 0.45). Yet, by thrombelastography (TEG) evaluated coagulation competence, albumin affected clot growth (TEG-angle 69 ± 5 vs 74° ± 3°, P blood loss (P = 0.042) while administration of albumin was related to the changes in TEG-MA (P = 0.029), aPPT (P blood loss as compared to infusion of LR. Also the use of HA did not affect the need for blood transfusion, the incidence of postoperative complications, or the hospital in-stay. Yet, albumin decreases coagulation competence during major surgery and the blood loss is related to TEG-MA rather than to plasma coagulation variables.

    Surgery induces a variety of metabolic, endocrine, and immune changes collectively known as the "stress response," which may often lead to prolonged postoperative convalescence. Anesthetic management may modulate this physiological response, thus affecting the postoperative course. We hypothesized that the intraoperative administration of dexmedetomidine (DEX), a sympatholytic agent, would reduce the stress response and improve the quality of recovery in patients undergoing major surgery. We conducted a prospective randomized double-blinded study of 54 patients undergoing multilevel spinal fusion. Anesthesia was maintained using either propofol/fentanyl/dexmedetomidine (PFD) or propofol/fentanyl/placebo-saline (PFS). The quality of recovery (a primary endpoint) was assessed using a 40-item quality of recovery questionnaire and a 9-question Fatigue Severity Scores. The tests were carried out preoperatively on postoperative days (POD) 1, 2, 3, and 30. Blood samples were collected at baseline, in the postanesthesia care unit, and at POD 1 and were analyzed for levels of cortisol, C-reactive proteins (CRP), and cytokines interleukin (IL)-1α, IL-1β, IL-1ra, IL-2, IL-6, IL-8, IL-10, and tumor necrosis factor-α. Data were analyzed using SPSS software (version 18) using a multivariate and mixed model approach to test for the effect of surgery and drug group. Pairwise comparisons were assessed by means of the t test or rank tests after correcting for multiple comparisons. The global 40-item quality of recovery questionnaire scores showed a significant effect of time (F(4,114)=22.63, Psize was not sufficient to detect differences either in the incidence of complications or in clinically relevant outcomes.

    The major gynecology surgery generally results in severe postoperative pain. Currently multimodal analgesia concept is widely used for the aim of postoperative pain relief optimization. According to this theory it is worth using the medication with different mechanism in order to increase analgesia qualify, decrease analgesic consumption and avoid adverse reaction. Unfortunately the surveys recently conducted have been pointed out the postoperative analgesia quality is still insufficient despite of using the concept mentioned above. One way to solve the problem is appearing in daily practice nefopam--centrally acting non-opioid analgesic that inhibits reuptake of serotonin, norepinephrine, and dopamine and also mitigates glutamatergic neurotransmission. In this trial we tried to assess the postoperative daily used analgesia quality and potency of preemptive multimodal analgesia model consisted of nefopam, ketoprofen, paracetamol and morphine.

    A pilot randomized controlled trial that evaluated the effect of remote ischemic preconditioning (RIPC) on clinical outcomes following major vascular surgery was performed. Eligible patients were those scheduled to undergo open abdominal aortic aneurysm repair, endovascular aortic aneurysm repair, carotid endarterectomy, and lower limb revascularization procedures. Patients were randomized to RIPC or to control groups. The primary outcome was a composite clinical end point comprising any of cardiovascular death, myocardial infarction, new-onset arrhythmia, cardiac arrest, congestive cardiac failure, cerebrovascular accident, renal failure requiring renal replacement therapy, mesenteric ischemia, and urgent cardiac revascularization. Secondary outcomes were components of the primary outcome and myocardial injury as assessed by serum troponin values. The primary outcome occurred in 19 (19.2%) of 99 controls and 14 (14.1%) of 99 RIPC group patients (P = .446). There were no significant differences in secondary outcomes. Our trial generated data that will guide future trials. Further trials are urgently needed. © The Author(s) 2015.

    Centers with large cardiac workloads may be presented with neonates who need major general surgery before correction or palliation of a serious cardiac defect. This is still a rare situation with only three short case reports available in the medical literature (1-3). We have reviewed the anesthetic and analgesic regimens of 18 such neonates who presented to the Birmingham Children's Hospital in the 4-year period 2004-2007. These children require meticulous preoperative evaluation and although it might be anticipated that they would pose a serious challenge to anesthetists, in reality with thorough investigation, preparation, and careful management, they tolerate general anesthesia well. These children may be transferred to centers of specialist pediatric cardiac anesthesia to be benefited from experience obtained there.

    Introduction Perioperative hypovolemia arises frequently and contributes to intestinal hypoperfusion and subsequent postoperative complications. Goal-directed fluid therapy might reduce these complications. The aim of this study was to compare the effects of goal-directed administration of crystalloids and colloids on the distribution of systemic, hepatosplanchnic, and microcirculatory (small intestine) blood flow after major abdominal surgery in a clinically relevant pig model. Methods Twenty-seven pigs were anesthetized and mechanically ventilated and underwent open laparotomy. They were randomly assigned to one of three treatment groups: the restricted Ringer lactate (R-RL) group (n = 9) received 3 mL/kg per hour of RL, the goal-directed RL (GD-RL) group (n = 9) received 3 mL/kg per hour of RL and intermittent boluses of 250 mL of RL, and the goal-directed colloid (GD-C) group (n = 9) received 3 mL/kg per hour of RL and boluses of 250 mL of 6% hydroxyethyl starch (130/0.4). The latter two groups received a bolus infusion when mixed venous oxygen saturation was below 60% ('lockout' time of 30 minutes). Regional blood flow was measured in the superior mesenteric artery and the celiac trunk. In the small bowel, microcirculatory blood flow was measured using laser Doppler flowmetry. Intestinal tissue oxygen tension was measured with intramural Clark-type electrodes. Results After 4 hours of treatment, arterial blood pressure, cardiac output, mesenteric artery flow, and mixed oxygen saturation were significantly higher in the GD-C and GD-RL groups than in the R-RL group. Microcirculatory flow in the intestinal mucosa increased by 50% in the GD-C group but remained unchanged in the other two groups. Likewise, tissue oxygen tension in the intestine increased by 30% in the GD-C group but remained unchanged in the GD-RL group and decreased by 18% in the R-RL group. Mesenteric venous glucose concentrations were higher and lactate levels were lower in the GD-C group

    The aim of this study was to identify the commonest referrals to a paediatric orthopaedic outpatient clinic and, therefore, to be able to improve the paediatric residency program in managing musculoskeletal problems. Demographic data, referrals and final diagnosis were collected prospectively on all patients that were evaluated in a paediatric orthopaedic outpatient clinic. The majority of referrals were to evaluate musculoskeletal pain (37%), foot deformity (20%), spine deformity (15%), walking pattern (11%), alignment of the lower limbs (4%), and development of the hip (4%). A normal physical examination or a normal variation was observed in 42% of patients. A mild condition was observed in 17% of patients that should have only been referred to a paediatric orthopaedic clinic after failing to resolve pain with anti-inflammatories or physiotherapy. A mild deformity that only needed treatment if it became symptomatic was seen in 8% of patients. The majority of referrals were due to a normal variation or mild conditions that only required symptomatic treatment. Paediatric residency programs do not reflect the prevalence of musculoskeletal conditions in clinical practice. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U.

    Full Text Available Background: Red cell distribution width (RDW has been shown to be associated with mortality in cardiac surgical patients. This study investigates the association of RDW with the 30-day mortality for those patients who undergo major- or ultra-major noncardiac surgery. Methods: Patients who received major- or ultra-major noncardiac surgery between July 2012 and May 2013 were included in the study and patients those with preoperative hemoglobin 13.35% (P = 0.025, odds ratio [OR]: 1.52, INR (P = 0.008, OR: 4.49, albumin level (P < 0.001, OR: 1.10, use of antihypertensives (P = 0.001, OR: 1.82, and preoperative pulse rate (P = 0.006, OR: 1.02 independently predicted the 30-day mortality. However, the area under receiver operating characteristic curve for the prediction of 30-day mortality using RDW was only 0.614. Conclusions: Although preoperative RDW independently predicted 30-day mortality in patients who underwent major- or ultra-major noncardiac surgery, it may not serve as an influential prognostic indicator in view of its low sensitivity and specificity.

    Effective, narcotic sparing analgesia is a major component of Enhanced Recovery Protocols (ERP), however the risk of poor analgesia and opioid related side effects (ORADE) remains an issue related to poor outcomes and satisfaction, and is strongly related to the risk of narcotic dependence after surgery. A variety of genes can impact narcotic and non-steroidal (NSAID) drug efficacy including: the CYP family (drug metabolism-narcotics and NSAID), or COMT/ABCB1/OPRM1 (functional receptor and transport activity for analgesia vs side effects). The purpose of this study was to perform the first assessment of the impact of a pharmacogenetics (PGx) guided selection of analgesics following major abdominal surgery within an ERP. A consecutive series of open and laparoscopic colorectal resections or major ventral hernia repair (PGx group) had a guided analgesic protocol based upon assessment of CYP1A2, CYP2C19, CYP2C9, CYP2D6, CYP3A4, CYP3A5, COMT, OPRM1, and ABCB1 genes. Study patients were compared to a recent historical series of patients (H group) managed using our well validated ERP. The primary outcome measure was the Overall Benefit of Analgesia Score (OBAS). Pain scores were also assessed. The data demonstrated a similar mix of procedures and gender between groups and more than half of the PGx group had revised analgesia from the standard ERP. The PGx group demonstrated significantly lower OBAS scores (p = 0.0.1) from POD1 (3.8 vs 5.4) through POD 5 (3.0 vs 4.5) Analgesia was also superior for the PGx group from POD1 through POD 5 (p = 0.04). Pharmacogenetics guidance resulted in frequent modifications of the analgesic program, resulting in excellent analgesia with a 50% reduction in narcotic consumption, and a reduced incidence of analgesic related side effects compared to our standard ERP. These data suggest further improvement in ERP resulting from a patient centric analgesic, reduced narcotic regimen which provides early and durable pain control with fewer

    Full Text Available Rationale. Pneumonia is a leading cause of postoperative complication. Objective. To examine trends, factors, and mortality of postoperative pneumonia following major cancer surgery (MCS. Methods. From 1999 to 2009, patients undergoing major forms of MCS were identified using the Nationwide Inpatient Sample (NIS, a Healthcare Cost and Utilization Project (HCUP subset, resulting in weighted 2,508,916 patients. Measurements. Determinants were examined using logistic regression analysis adjusted for clustering using generalized estimating equations. Results. From 1999 to 2009, 87,867 patients experienced pneumonia following MCS and prevalence increased by 29.7%. The estimated annual percent change (EAPC of mortality after MCS was −2.4% (95% CI: −2.9 to −2.0, P<0.001; the EAPC of mortality associated with pneumonia after MCS was −2.2% (95% CI: −3.6 to 0.9, P=0.01. Characteristics associated with higher odds of pneumonia included older age, male, comorbidities, nonprivate insurance, lower income, hospital volume, urban, Northeast region, and nonteaching status. Pneumonia conferred a 6.3-fold higher odd of mortality. Conclusions. Increasing prevalence of pneumonia after MCS, associated with stable mortality rates, may result from either increased diagnosis or more stringent coding. We identified characteristics associated with pneumonia after MCS which could help identify at-risk patients in order to reduce pneumonia after MCS, as it greatly increases the odds of mortality.

    Bone graft is widely used within orthopaedic surgery especially in revision joint arthroplasty and spine fusion. The early implant fixation in the revision situation of loose joint prostheses is important for the long-term survival. Bone autograft has been considered as gold standard in many...... orthopaedic procedures, whereas allograft is the gold standard by replacement of extensive bone loss. However, the use of autograft is associated with donor site morbidity, especially chronic pain. In addition, the limited supply is a significant clinical challenge. Limitations in the use of allograft include...... bone and includes bone collagen, morphogenetic proteins and growth factors. The combination of DBM with CB and with allograft might improve the healing potential of these grafts around non-cemented orthopaedic implants and thereby the implant fixation.

    Health services in the United States and Europe have reported that tele-orthopaedics saves significant patient travel time, reduces time off work, increases satisfaction with care and in some scenarios reduces the cost of care. Less is known about the role of tele-orthopaedics in Australia. The aim of this study was to explore Australian-based tele-orthopaedic services, and to identify the barriers and enablers associated with these services. We used a qualitative case study methodology where specific services were identified from multiple sources and invited to participate in a structured interview. Nine tele-orthopaedic services contributed to the study. Telehealth activity in each service ranged from one to 75 patients per week, and service maturity ranged from three months to 10 years. Services were used predominantly for fracture clinics and peri-operative consultations. The majority (78%) of services used videoconferencing. Two services used asynchronous methods to review radiographs without direct patient involvement. Tele-orthopaedics was found to be disruptive as it required the redesign of many care processes. However, all services found the redesign feasible. Staff resistance was a commonly cited barrier. Further, imaging repositories from multiple imaging providers complicated access to information. Key enablers included clinical champions, picture archiving and communication systems, and the perceived benefit to patients who would avoid the need for travel. Whilst it appears that tele-orthopaedics is not widely utilised in Australia, recognition of the barriers and enablers is important for the development of similar services.

    With the advent of smartphones together with their downloadable applications (apps), there is increasing opportunities for doctors, including orthopaedic sports surgeons, to integrate such technology into clinical practice. However, the clinical reliability of these medical apps remains questionable. We reviewed available apps themed specifically towards Orthopaedic Sports Medicine and related conditions and assessed the level of medical professional involvement in their design and content, along with a review of these apps. The most popular smartphone app stores (Android, Apple, Blackberry, Windows, Samsung, Nokia) were searched for Orthopaedic Sports medicine themed apps, using the search terms; Orthopaedic Sports Medicine, Orthopaedics, Sports medicine, Knee Injury, Shoulder Injury, Anterior Cruciate Ligament Tear, Medial Collateral Ligament Tear, Rotator Cuff Tear, Meniscal Tear, Tennis Elbow. All English language apps related to orthopaedic sports medicine were included. A total of 76 individual Orthopaedic Sports Medicine themed apps were identified. According to app store classifications, there were 45 (59 %) medical themed apps, 28 (37 %) health and fitness themed apps, 1 (1 %) business app, 1 (1 %) reference app and 1 (1 %) sports app. Forty-nine (64 %) apps were available for download free of charge. For those that charged access, the prices ranged from £0.69 to £69.99. Only 51 % of sports medicine apps had customer satisfaction ratings and 39 % had named medical professional involvement in their development or content. We found the majority of Orthopaedic Sports Medicine apps had no named medical professional involvement, raising concerns over their content and evidence-base. We recommend increased regulation of such apps to improve the accountability of app content.

    Full Text Available To assess the ability of the urinary biomarkers IGFBP7 (insulin-like growth factor-binding protein 7 and TIMP-2 (tissue inhibitor of metalloproteinase 2 to early predict acute kidney injury (AKI in high-risk surgical patients.Postoperative AKI is associated with an increase in short and long-term mortality. Using IGFBP7 and TIMP-2 for early detection of cellular kidney injury, thus allowing the early initiation of renal protection measures, may represent a new concept of evaluating renal function.In this prospective study, urinary [TIMP-2]×[IGFBP7] was measured in surgical patients at high risk for AKI. A predefined cut-off value of [TIMP-2]×[IGFBP7] >0.3 was used for assessing diagnostic accuracy. Perioperative characteristics were evaluated, and ROC analyses as well as logistic regression models of risk assessment were calculated with and without a [TIMP-2]×[IGFBP7] test.107 patients were included in the study, of whom 45 (42% developed AKI. The highest median values of biomarker were detected in septic, transplant and patients after hepatic surgery (1.24 vs 0.45 vs 0.47 ng/l²/1000. The area under receiving operating characteristic curve (AUC for the risk of any AKI was 0.85, for early use of RRT 0.83 and for 28-day mortality 0.77. In a multivariable model with established perioperative risk factors, the [TIMP-2]×[IGFBP7] test was the strongest predictor of AKI and significantly improved the risk assessment (p<0.001.Urinary [TIMP-2]×[IGFBP7] test sufficiently detect patients with risk of AKI after major non-cardiac surgery. Due to its rapid responsiveness it extends the time frame for intervention to prevent development of AKI.

The non-vitamin K antagonist oral anticoagulant rivaroxaban has demonstrated superior efficacy and similar safety to all tested regimens of enoxaparin in large Phase III clinical studies of venous thromboembolism prevention after elective hip and knee arthroplasty. Despite regulatory approval of rivaroxaban for this indication, concerns remain among physicians regarding its optimal and effective use in routine clinical practice. Real-life studies, such as XAMOS and ORTHO-TEP, are providing physicians with more information on the routine use of rivaroxaban for venous thromboembolism prevention after orthopedic surgery, helping to establish its safety and effectiveness in everyday clinical care. Among the most important issues are the risk of bleeding complications, wound healing, timing of first dose, impact of type of anesthesia on thromboprophylaxis effectiveness, patient comorbidities and comedication use, periprocedural management, associated costs, and clinical outcomes in trauma-related fractures. Many of these issues are difficult to study in randomized, double-blind, Phase III trials, and can be assessed more readily using real-life data. In particular, real-life or noninterventional studies lack many of the strict inclusion and exclusion criteria associated with Phase III trials and involve unselected patients who often present with significant comorbidities or comedication use.

    To examine associations between the inflammatory marker C-reactive protein (CRP) measured preoperatively and on postoperative day 2 (POD2) and delirium incidence, duration, and feature severity. Prospective cohort study. Two academic medical centers. Adults aged 70 and older undergoing major noncardiac surgery (N = 560). Plasma CRP was measured using enzyme-linked immunosorbent assay. Delirium was assessed from Confusion Assessment Method (CAM) interviews and chart review. Delirium duration was measured according to number of hospital days with delirium. Delirium feature severity was defined as the sum of CAM-Severity (CAM-S) scores on all postoperative hospital days. Generalized linear models were used to examine independent associations between CRP (preoperatively and POD2 separately) and delirium incidence, duration, and feature severity; prolonged hospital length of stay (LOS, >5 days); and discharge disposition. Postoperative delirium occurred in 24% of participants, 12% had 2 or more delirium days, and the mean ± standard deviation sum CAM-S was 9.3 ± 11.4. After adjusting for age, sex, surgery type, anesthesia route, medical comorbidities, and postoperative infectious complications, participants with preoperative CRP of 3 mg/L or greater had a risk of delirium that was 1.5 times as great (95% confidence interval (CI) = 1.1-2.1) as that of those with CRP less than 3 mg/L, 0.4 more delirium days (P delirium (3.6 CAM-S points higher, P delirium (95% CI = 1.0-2.4) as those in the lowest quartile (≤127.53 mg/L), had 0.2 more delirium days (P delirium (4.5 CAM-S points higher, P delirium incidence, duration, and feature severity. CRP may be useful to identify individuals who are at risk of developing delirium. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    Patients undergoing major heart surgery (MHS) represent a special subpopulation at risk for nosocomial infections. Postoperative infection is the main non-cardiac complication after MHS and has been clearly related to increased morbidity, use of hospital resources and mortality. Our aim was to determine the incidence, aetiology, risk factors and outcome of ventilator-associated pneumonia (VAP) in patients who have undergone MHS in Europe. Our study was a prospective study of patients undergoing MHS in Europe who developed suspicion of VAP. During a one-month period, participating units submitted a protocol of all patients admitted to their units who had undergone MHS. Overall, 25 hospitals in eight different European countries participated in the study. The number of patients intervened for MHS was 986. Fifteen patients were excluded because of protocol violations. One or more nosocomial infections were detected in 43 (4.4%) patients. VAP was the most frequent nosocomial infection (2.1%; 13.9 episodes per 1000 days of mechanical ventilation). The microorganisms responsible for VAP in this study were: Enterobacteriaceae (45%), Pseudomonas aeruginosa (20%), methicillin-resistant Staphylococcus aureus (10%) and a range of other microorganisms. We identified the following significant independent risk factors for VAP: ascending aorta surgery (odds ratio (OR) = 6.22; 95% confidence interval (CI) = 1.69 to 22.89), number of blood units transfused (OR = 1.08 per unit transfused; 95% CI = 1.04 to 1.13) and need for re-intervention (OR = 6.65; 95% CI = 2.10 to 21.01). The median length of stay in the intensive care unit was significantly longer (P < 0.001) in patients with VAP than in patients without VAP (23 days versus 2 days). Death was significantly more frequent (P < 0.001) in patients with VAP (35% versus 2.3%). Patients undergoing aortic surgery and those with complicated post-intervention courses, requiring multiple transfusions or re-intervention, constitute a high

    The future of orthopaedic surgery will be shaped by unprecedented demographic and economic challenges, necessitating movement to so-called "second curve" innovations in the delivery of care. Implementation of integrated care pathways (ICPs) may be one solution to imminent cost and access pressures facing orthopaedic patients in this era of health-care accountability and reform. ICPs can lower costs and the duration of hospital stay while facilitating better outcomes through enhanced interspecialty communication. As with any innovation at the crossroads of paradigm change, implementation of integrated care pathways for orthopaedics may elicit surgeons' concern on a variety of grounds and on levels ranging from casual questioning to vehement opposition. No single method is always effective in promoting cooperation and adoption, so a combination of strategies offers the best chance of success. With a special focus on total joint replacement, we consider general patterns of resistance to change, styles of conflict, and specific issues that may underlie orthopaedic surgeon resistance to implementation of integrated care pathways. Methods to facilitate and sustain orthopaedic surgeon engagement in implementation of such pathways are discussed.

This trend has been attributed to negative perceptions among women medical students of workplace culture and lifestyle in orthopaedics as well as lack of exposure, particularly during medical school when most women decide to enter the field. Since 2012, The Perry Initiative, a nonprofit organization that is focused on recruiting and retaining women in orthopaedics, had conducted extracurricular outreach programs for first- and second-year female medical students to provide exposure and mentoring opportunities specific to orthopaedics. This program, called the Medical Student Outreach Program (MSOP), is ongoing at medical centers nationwide and has reached over 300 medical students in its first 3 program years (2012-2014). (1) What percentage of MSOP participants eventually match into orthopaedic surgery residency? (2) Does MSOP impact participants' perceptions of the orthopaedics profession as well as intellectual interest in the field? The percentage of program alumnae who matched into orthopaedics was determined by annual followup for our first two cohorts who graduated from medical school. All program participants completed a survey immediately before and after the program that assessed the impact of MSOP on the student's intention to pursue orthopaedics as well as perceptions of the field and intellectual interest in the discipline. The orthopaedic surgery match rate for program participants was 31% in our first graduating class (five of 16 participants in 2015) and 28% in our second class (20 of 72 participants in 2016). Pre/post program comparisons showed that the MSOP influenced students' perceptions of the orthopaedics profession as well as overall intellectual interest in the field. The results of our study suggest that

Attention should be given to the total chain of motion, of which the shoulder itself is only a part. We conclude that physiotherapy management is of major importance in any invasive or orthopaedic procedure, regardless of which joints are involved. Both pre- and postoperative physiotherapy, as part of comprehensive care is needed to achieve optimal functional outcome and therefore optimal quality of life for people with haemophilia.

  18. Fathers of orthopaedics in Germany (eighteenth and early nineteenth centuries): Lorenz Heister in Helmsted; Johann Friedrich Dieffenbach in Berlin; Heine and family in Würzburg.

    Hernigou, Philippe

    2016-02-01

    In orthopaedic medicine in Germany, Lorenz Heister, practicing in the eighteenth century, is considered one of the fathers of German surgery and is renowned for his books on management of hemorrhage, wounds, fractures, bandaging, instrumentation and surgery. After Heister, at the beginning of the nineteenth century, orthopaedic medicine in Germany developed uniformly. In a period when few doctors were interested in a separate discipline of orthopaedics, Germany led in this field. Heine devoted himself to the development of the new profession of orthopaedics, and in 1816, he opened the first orthopaedic institute on German soil in the former monastery of St. Stephen, which later became known as the Karolinen-Institut. Along with Heine and his family, the special development of orthopaedics in Berlin may be attributed to the work of Dieffenbach who, in 1832, became professor at the University of Berlin and in 1840 director of the Clinical Institute for Surgery at Charité Hospital.

    Objective Major life stressors, including major surgeries, are often followed by psychiatric symptoms and disorders. Prior retrospective work found abdominal-aortic aneurysm (AAA) repair is followed by increased psychiatric morbidity, which may adversely influence physical and functional recovery. Identifying risk factors prior to surgery, such as dysregulation in stress response systems, might be useful to improving preventative intervention. Methods Two hundred and sixteen patients receiving open AAA or aortofemoral bypass (AFB) surgeries, endovascular AAA repair (EVAR), or nonsurgical AAA treatment were recruited from two vascular surgery services. Psychiatric symptoms and salivary cortisol measures (waking, 4 pm, and 11 pm, before and after low-dose dexamethasone) were obtained at intake and 3 and 9 month followups. Results Following open surgeries, 18% of patients had new psychiatric disorders, compared to 4% of patients receiving EVAR or nonsurgical treatment (odds ratio = 6.0, 95% CI 1.6 - 22.1, p=.007). Having a history of major depression predicted onset of new disorders in surgical patients. Pre-surgical cortisol levels were associated with both baseline (r=.23, p<.05) and 9 month (r=.32, p<.01) psychiatric symptoms (cortisol B=1.0, SE=0.48, p<.05 in repeated measures mixed model). Conclusion Open AAA repair surgery is prospectively linked to development of psychiatric morbidity, and history of depression elevates risk. Cortisol measures prior to surgery are associated with current and future psychological functioning, suggesting potential neurobiological mechanisms that may contribute to vulnerability. These results can help identify surgical patients at risk, and point to potential targets for risk reduction interventions. PMID:26461854

    Opioids are commonly used as effective analgesics for the treatment of acute and chronic pain. However, considerable individual differences have been widely observed in sensitivity to opioid analgesics. We focused on a G-protein-activated inwardly rectifying potassium (GIRK) channel subunit, GIRK2, that is an important molecule in opioid transmission. In our initial polymorphism search, a total of nine single-nucleotide polymorphisms (SNPs) were identified in the whole exon, 5'-flanking, and exon-intron boundary regions of the KCNJ6 gene encoding GIRK2. Among them, G-1250A and A1032G were selected as representative SNPs for further association studies. In an association study of 129 subjects who underwent major open abdominal surgery, the A/A genotype in the A1032G SNP and -1250G/1032A haplotype were significantly associated with increased postoperative analgesic requirements compared with other genotypes and haplotypes. The total dose (mean+/-SEM) of rescue analgesics converted to equivalent oral morphine doses was 20.45+/-9.27 mg, 10.84+/-2.24 mg, and 13.07+/-2.39 mg for the A/A, A/G, and G/G genotypes in the A1032G SNP, respectively. Additionally, KCNJ6 gene expression levels in the 1032A/A subjects were significantly decreased compared with the 1032A/G and 1032G/G subjects in a real-time quantitative PCR analysis using human brain tissues, suggesting that the 1032A/A subjects required more analgesics because of lower KCNJ6 gene expression levels and consequently insufficient analgesic effects. The results indicate that the A1032G SNP and G-1250A/A1032G haplotype could serve as markers that predict increased analgesic requirements. Our findings will provide valuable information for achieving satisfactory pain control and open new avenues for personalized pain treatment.

    2001-03-01

    Abdominal wall or parastomal hernias following major genitourinary or abdominal surgery are a significant surgical problem. Open surgical repair is difficult because of adhesion formation and poor definition of the hernia fascial edges. Laparoscopic intervention has allowed effective correction of these abdominal wall hernias. From November 1997 to June 2000, 14 male and 3 female patients underwent laparoscopic abdominal wall herniorrhaphy at our institution. Of these, 13 patients received incisional and 4 parastomal hernia repair. All hernia defects were repaired using a measured piece of Gore-Tex DualMesh. A retrospective review of each patient's history and operative characteristics was undertaken. All repairs were successful. No patient required conversion to an open procedure, and there were no intraoperative complications. The average operative time was 4 (range 2.5-6.5) and 4.3 (range 3.75-5.5) hours in the incisional and parastomal group, respectively. The average hospital stay was 4.9 days (range 2-12) for the incisional group and 3.8 (range 3-4) days for the parastomal group. To date, two patients experienced a recurrence of incisional hernias, at 5 and 8 months postoperatively. No recurrences have developed in the parastomal hernia repairs at 2 to 33 months. Laparoscopic repair of abdominal wall incisional or parastomal hernias provides an excellent anatomic correction of such defects. Adhesions are lysed under magnified laparoscopic vision, and the true limits of the fascial defects are clearly identified. The DualMesh is easy to work with and has yielded excellent results. A comparison with open repair with respect to perioperative factors and long-term success is currently under way.

  12. Using financial incentives to improve value in orthopaedics.

    2012-04-01

    A variety of reforms to traditional approaches to provider payment and benefit design are being implemented in the United States. There is increasing interest in applying these financial incentives to orthopaedics, although it is unclear whether and to what extent they have been implemented and whether they increase quality or reduce costs. We reviewed and discussed physician- and patient-oriented financial incentives being implemented in orthopaedics, key challenges, and prerequisites to payment reform and value-driven payment policy in orthopaedics. We searched the MEDLINE database using as search terms various provider payment and consumer incentive models. We retrieved a total of 169 articles; none of these studies met the inclusion criteria. For incentive models known to the authors to be in use in orthopaedics but for which no peer-reviewed literature was found, we searched Google for further information. Provider financial incentives reviewed include payments for reporting, performance, and patient safety and episode payment. Patient incentives include tiered networks, value-based benefit design, reference pricing, and value-based purchasing. Reform of financial incentives for orthopaedic surgery is challenged by (1) lack of a payment/incentive model that has demonstrated reductions in cost trends and (2) the complex interrelation of current pay schemes in today's fragmented environment. Prerequisites to reform include (1) a reliable and complete data infrastructure; (2) new business structures to support cost sharing; and (3) a retooling of patient expectations. There is insufficient literature reporting the effects of various financial incentive models under implementation in orthopaedics to know whether they increase quality or reduce costs. National concerns about cost will continue to drive experimentation, and all anticipated innovations will require improved collaboration and data collection and reporting.

  13. Dabigatran in the prevention of venous thromboembolism after major orthopedic surgery

    Directory of Open Access Journals (Sweden)

    Orietta Zaniolo

    2009-09-01

    Full Text Available Venous thromboembolism (VTE is a very frequent surgical complication, especially in major orthopedic procedures. Prophylaxis with pharmacological agents, including warfarin and subcutaneous injection of either low-molecular weight heparin (LMWH or low-dose unfractionated heparin, and/or with mechanical methods has been shown to be effective and safe. Despite recommendations on the routine implementation of these prophylaxis methods, some surveys demonstrate that many patients currently don’t receive any prophylaxis. The recent introduction of dabigatran etexilate, a novel oral direct thrombin inhibitor approved for VTE prophylaxis in total knee and hip substitution, represents a major advance in the provision of efficient anticoagulation therapy. Two pivotal randomized controlled multicenter trials assessed non-inferiority of dabigatran 150/220 mg/day versus enoxaparin 40 mg/day in the prevention of VTE after hip and knee replacement. From an economical point of view, an English modeling study on dabigatran cost/effectiveness showed it to be associated with lower cost and slightly higher gain in Quality Adjusted Life Years, thus dominating enoxaparin. Other analyses obtained results consistent with these, estimating inferior costs related to the use of dabigatran with respect to low weight heparin; this difference was mainly due to health personnel work for heparins subcutaneous administration. In Italy, acquisition costs for a 28-35 days therapeutic cycle of main antithrombotic drugs vary between 70 and 170 €, according to different distribution policy. Dabigatran, with a cost of 117 €, holds a medial position. Cost savings related to oral administration may partially offset the price difference between dabigatran and the less expensive options among LMWHs or, compared with the more expensive ones, add to pharmaceutical cost savings. In order to increase the effectiveness of VTE prophylaxis, the improvement of patient adherence to the

    To evaluate the incidence of venous thromboembolism in spine surgery with no chemical and mechanical prophylaxis, and to determine the specific risk factors for this complication. A historical cohort was analysed. All patients subjected to major spinal surgery, between January 2010 and September 2014, were included. No chemical or mechanical prophylaxis was administered in any patient. Active mobilisation of lower limbs was indicated immediately after surgery, and early ambulation started in the first 24-48 hours after surgery. Clinically symptomatic cases were confirmed by Doppler ultrasound of the lower limbs or chest CT angiography. A sample of 1092 cases was studied. Thromboembolic events were observed in 6 cases (.54%); 3 cases (.27%) with deep venous thrombosis and 3 cases (.27%) with pulmonary thromboembolism. A lethal case was identified (.09%). There were no cases of major bleeding or epidural haematoma. The following risk factors were identified: a multilevel fusion at more than 4 levels, surgeries longer than 130 minutes, patients older than 70 years of age, hypertension, and degenerative scoliosis. There is little scientific evidence on the prevention of thromboembolic events in spinal surgery. In addition to the disparity of prophylactic methods indicated by different specialists, it is important to weigh the risk-benefit of intra- and post-operative bleeding, and even the appearance of an epidural haematoma. Prophylaxis should be assessed in elderly patients over 70 years old, who are subjected to surgeries longer than 130 minutes, when 4 or more levels are involved. Copyright © 2015 SECOT.

    For treating patients with scoliosis orthopaedic surgeons need diagnostic imaging procedures in order to provide answers about a possible underlying disease, choice of treatment, and prognosis. Once treatment is instituted, imaging is also critical for monitoring changes of the deformity so as to optimize therapy. The combined effort of orthopaedic surgeons and radiologists helps detect treatable causes of scoliosis at an early stage, define the need and timing for surgery, and ensure that every precaution is taken to minimize the risks of surgery. Neurosurgical causes, with particular reference to spinal cord tumours and syringomyelia, need to be addressed before scoliosis surgery can be contemplated.

    Postoperative non-cardiac complication rates are as high as 11-28% after high-risk abdominal procedures. Emerging evidence indicates that postoperative cardiac troponin T elevations are associated with adverse outcome in non-cardiac surgery. The aim of this study was to determine the relationship between postoperative high-sensitive cardiac troponin T elevations and non-cardiac complications in patients after major abdominal surgery. This prospective observational single-centre cohort study included patients at risk for coronary artery disease undergoing elective major abdominal surgery. Cardiac troponin was measured before surgery and at day 1, 3, and 7. Multivariable logistic regression analysis was performed to examine the adjusted association for different cut-off concentrations of postoperative myocardial injury and non-cardiac outcome. In 203 patients, 690 high-sensitive cardiac troponin T measurements were performed. Fifty-three patients (26%) had a non-cardiac complication within 30 days after surgery. Hospital mortality was 4% (8/203). An increase in cardiac troponin T concentration ≥100% compared with baseline was a superior independent predictor of non-cardiac postoperative clinical complications (adjusted odds ratio 4.3, 95% confidence interval 1.8-10.1, Pcardiac troponin T increase ≥100% is a strong predictor of non-cardiac 30 day complications, increased hospital stay and hospital mortality in patients undergoing major abdominal surgery.

    Background. Evidence suggests that endothelial dysfunction in the early postoperative period promotes myocardial injury after non-cardiac surgery. The aim of this study was to investigate the impact of colon cancer surgery on endothelial function and the association with the l-arginine-nitric oxide...... pathway postoperatively. Methods. Patients undergoing elective colon cancer surgery (n = 31) were included in this prospective observational cohort study. Endothelial function, as measured using the reactive hyperaemia index (RHI), was assessed non-invasively using digital pulse tonometry. RHI and plasma...... was attenuated in the first days after colon cancer surgery indicating acute endothelial dysfunction. Endothelial dysfunction correlated with disturbances in the L-arginine – nitric oxide pathway. Our findings provide a rationale for investigating the hypothesized association between acute endothelial...

    Major surgery is accompanied by extensive proteolysis of insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3). Proteolysis of IGFBP-3 is generally believed to increase IGF bioavailability due to a diminished affinity of the IGFBP-3 fragments for IGFs. We have investigated 18 patients...... undergoing elective ileo-anal J-pouch surgery. Patients were randomized to treatment with GH (12 IU/day; n = 9) or placebo (n = 9) from 2 days before to 7 days after operation.

    2008-01-01

    This article revisits the application of orthopaedic service lines from early introduction and growth of this organizational approach in the 1980s, through the 1990s, and into the current decade. The author has experienced and worked in various service-line structures through these three decades, as well as the preservice-line era of 1970s orthopaedics. Past lessons learned during earlier phases and then current trends and analysis by industry experts are summarized briefly, with indication given of the future for service lines. Variation versus consistency of certain elements in service-line definitions and in operational models is discussed. Main components of service-line structures and typical processes are described briefly, along with a more detailed section on the service-line director/manager role. Current knowledge contained here will help guide the reader to more "out-of-the-box" thinking toward comprehensive orthopaedic centers of excellence.

  10. Thromboembolism prophylaxis practices in orthopaedic arthroplasty patients.

    LENUS (Irish Health Repository)

    Cawley, D

    2010-10-01

    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.

    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.

    Social media presents unique opportunities and challenges for practicing orthopaedic surgeons. Social media, such as blogging, Facebook, and Twitter, provides orthopaedic surgeons with a new and innovative way to communicate with patients and colleagues. Social media may be a way for orthopaedic surgeons to enhance communication with patients and healthcare populations; however, orthopaedic surgeons must recognize the limitations of social media and the pitfalls of increased connectedness in patient care.

    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.

    2008-03-01

    The Accreditation Council of Graduate Medical Education's (ACGME) Data Accreditation System indicates 124 of 152 orthopaedic surgery residency program directors have 5 or fewer years of tenure. The qualifications and responsibilities of the position based on the requirements of orthopaedic surgery residency programs, the institutions that support them, and the ACGME Outcome Project have evolved the role of the program coordinator from clerical to managerial. To fill the void of information on the coordinators' expanding roles and responsibilities, the 2006 Association of Residency Coordinators in Orthopaedic Surgery (ARCOS) Career survey was designed and distributed to 152 program coordinators in the United States. We had a 39.5% response rate for the survey, which indicated a high level of day-to-day managerial oversight of all aspects of the residency program; additional responsibilities for other department or division functions for fellows, rotating medical students, continuing medical education of the faculty; and miscellaneous business functions. Although there has been expansion of the role of the program coordinator, challenges exist in job congruence and position reclassification. We believe use of professional groups such as ARCOS and certification of program coordinators should be supported and encouraged.

    Interest in medical errors has increased during the last few years owing to the number of medical malpractice claims. Reasons for the increasing number of claims may be related to patients' higher expectations, iatrogenic injury, and the growth of the legal services industry. Claims analysis provides helpful information in specialties in which a higher number of errors occur, highlighting areas where orthopaedic care might be improved. We determined: (1) the number of claims involving orthopaedics and traumatology in Rome; (2) the risk of litigation in elective and trauma surgery; (3) the most common surgical procedures involved in claims and indemnity payments; (4) the time between the adverse medical event and the judgment date; and (5) issues related to informed consent. We analyzed 1925 malpractice judgments decided in the Civil Court of Rome between 2004 and 2010. In total, 243 orthopaedics claims were filed, and in 75% of these cases surgeons were found liable; 149 (61%) of these resulted from elective surgery. Surgical teams were sued in 30 claims and found liable in 22. The total indemnity payment ordered was more than €12,350,000 (USD 16,190,000). THA and spinal surgery were the most common surgical procedures involved. Inadequate informed consent was reported in 5.3% of cases. Our study shows that careful medical examination, accurate documentation in medical records, and adequate informed consent might reduce the number of claims. We suggest monitoring of court judgments would be useful to develop prevention strategies to reduce claims.

    Mediastinitis caused by methicillin-resistant Staphylococcus aureus (MRSA) is a serious complication after pediatric cardiac surgery. An outbreak of surgical site infections (SSIs) provided the motivation to implement SSI prevention measures in our institution. Subjects comprised 174 pediatric patients who underwent open-heart surgery after undergoing preoperative nasal culture screening. The incidence of SSIs and mediastinitis was compared between an early group, who underwent surgery before SSI measures (Group E, n = 73), and a recent group, who underwent surgery after these measures (Group R, n = 101), and factors contributing to the occurrence of mediastinitis were investigated. The incidence of both SSIs and Mediastinitis has significantly decreased after SSI measures. With regard to factors that significantly affected mediastinitis, preoperative factors were "duration of preoperative hospitalization" and "preoperative MRSA colonization," intraoperative factors were "Aristotle basic complexity score," "operation time," "cardiopulmonary bypass circuit volume" and "lowest rectal temperature." And postoperative factor was "blood transfusion volume." Patients whose preoperative nasal cultures were MRSA-positive suggested higher risk of MRSA mediastinitis. SSI prevention measures significantly reduced the occurrence of SSIs and mediastinitis. Preoperative MRSA colonization should be a serious risk factor for mediastinitis following pediatric cardiac surgeries.

    Introduction A bloodless surgery can be desirable also for non Jehovah’s witnesses patients, but requires a team approach from the very first assessment to ensure adequate planning. Presentation of the case Our patient, a Jehovah’s witnesses, was scheduled for right lower lobectomy due to pulmonary adenocarcinoma. Her firm denies to receive any kind of transfusions, forced clinicians to a bloodless management of the case. Discussion Before surgery a meticulous coagulopathy research and hemodynamic optimization are useful to prepare patient to operation. During surgery, controlled hypotension can help to obtain effective hemostasis. After surgery, clinicians monitored any possible active bleeding, using continuous noninvasive hemoglobin monitoring, limiting the blood loss due to serial in vitro testing. The optimization of cardiac index and delivery of oxygen were continued to grant a fast recovery. Conclusion Bloodless surgery is likely to gain popularity, and become standard practice for all patients. The need for transfusion should be targeted on individual case, avoiding strictly fixed limit often leading to unnecessary transfusion. PMID:27107502

  19. Effect of major and minor surgery on plasma levels of arginine, citrulline, nitric oxide metabolites, and ornithine in humans.

    To determine the effect of surgical invasiveness on plasma levels of arginine, citrulline, ornithine, and nitric oxide (NO) in humans. Surgical trauma may have a profound effect on the metabolism of NO. However, human studies reported both increased and decreased NO levels after hemorrhagic shock. Arginine, citrulline, and ornithine are key amino acids involved in NO metabolism, but studies evaluating these amino acids together with NO and during 2 types of surgery are lacking. This study tests the hypothesis that major surgery has a more profound effect on plasma levels of arginine, citrulline, NO, and ornithine than minor surgery. Fifteen patients undergoing minor surgery (vulvectomy) and 13 patients undergoing major surgery (laparotomy) were prospectively followed up for 4 days. Plasma was collected for evaluation of levels of arginine, citrulline, NO, and ornithine. Throughout the experiment, arginine levels did not significantly differ between experimental groups. Perioperative plasma citrulline levels were significantly lower in the laparotomy group than in the vulvectomy group, whereas both groups showed a decrease in citrulline levels at the end of the operation and 24 hours postoperatively. Roughly the same pattern was seen for plasma NO and ornithine levels. However, ornithine levels in the laparotomy group showed a more drastic decrease at the end of the operation and 24 hours postoperatively than citrulline and NO levels. The level of surgical invasiveness has the most profound effect on plasma levels of ornithine. In addition, heavier surgical trauma is paired with lower postoperative levels of citrulline and NO metabolites than lighter surgery. It is suggested that surgical trauma stimulates the laparotomy group to consume significantly more ornithine, possibly for use in wound healing.

    Emergency surgery or transarterial embolization (TAE) are options for the treatment of recurrent or refractory nonvariceal upper gastrointestinal bleeding. Surgery has the disadvantage of high rates of postoperative morbidity and mortality. Embolization has become more available and has the advantage of avoiding laparotomy in this often unfit and elderly population. To carry out a systematic review and meta-analysis of all studies that have directly compared TAE with emergency surgery in the treatment of major upper gastrointestinal bleeding that has failed therapeutic upper gastrointestinal endoscopy. A literature search of Ovid MEDLINE, Embase, and Google Scholar was performed. The primary outcomes were all-cause mortality and rates of rebleeding. The secondary outcomes were length of stay and postoperative complications. A total of nine studies with 711 patients (347 who had embolization and 364 who had surgery) were analyzed. Patients in the TAE group were more likely to have ischemic heart disease (odds ratio [OR] =1.99; 95% confidence interval [CI]: 1.33, 2.98; P=0.0008; I (2)=67% [random effects model]) and be coagulopathic (pooled OR =2.23; 95% CI: 1.29, 3.87; P=0.004; I (2)=33% [fixed effects model]). Compared with TAE, surgery was associated with a lower risk of rebleeding (OR =0.41; 95% CI: 0.22, 0.77; P<0.0001; I (2)=55% [random effects]). There was no difference in mortality (OR =0.70; 95% CI: 0.48, 1.02; P=0.06; I (2)=44% [fixed effects]) between TAE and surgery. When compared with surgery, TAE had a significant increased risk of rebleeding rates after TAE; however, there were no differences in mortality rates. These findings are subject to multiple sources of bias due to poor quality studies. These findings support the need for a well-designed clinical trial to ascertain which technique is superior.

Surgery has the disadvantage of high rates of postoperative morbidity and mortality. Embolization has become more available and has the advantage of avoiding laparotomy in this often unfit and elderly population.Objective: To carry out a systematic review and meta-analysis of all studies that have directly compared TAE with emergency surgery in the treatment of major upper gastrointestinal bleeding that has failed therapeutic upper gastrointestinal endoscopy.Methods: A literature search of Ovid MEDLINE, Embase, and Google Scholar was performed. The primary outcomes were all-cause mortality and rates of rebleeding. The secondary outcomes were length of stay and postoperative complications.Results: A total of nine studies with 711 patients (347 who had embolization and 364 who had surgery were analyzed. Patients in the TAE group were more likely to have ischemic heart disease (odds ratio [OR] =1.99; 95% confidence interval [CI]: 1.33, 2.98; P=0.0008; I2=67% [random effects model] and be coagulopathic (pooled OR =2.23; 95% CI: 1.29, 3.87; P=0.004; I2=33% [fixed effects model].

    INTRODUCTION: Evidence for the effect of post-operative abdominal binders on post-operative pain, seroma formation, physical function, pulmonary function and increased intra-abdominal pressure among patients after surgery remains largely un-investigated. METHODS: A systematic review was conducted....... The PubMed, EMBASE and Cochrane databases were searched for studies on the use of abdominal binders after abdominal surgery or abdominoplasty. All types of clinical studies were included. Two independent assessors evaluated the scientific quality of the studies. The primary outcomes were pain, seroma...... to reduce seroma formation after laparoscopic ventral herniotomy and a non-significant reduction in pain. Physical function was improved, whereas evidence supports a beneficial effect on psychological distress after open abdominal surgery. Evidence also supports that intra-abdominal pressure increases...

    Full Text Available Abstract Background Borderline ovarian tumors (BOTs are a subset of epithelial ovarian tumors with low malignant potential but significant risk of relapse (10% to 30%. Unfortunately, surgical prognostic factors for BOT relapse have not been clearly identified, probably due to the use of heterogeneous surgical definitions and limited follow-up. The aim of this study was to assess potential relapse risk factors using standard surgical definitions and long follow-up. Methods All patients diagnosed with BOT for a period of more than 10 years in a single institution were included in the analysis. Complete surgical staging was defined as the set of procedures that follow standard guidelines for staging surgery (except lymphadenectomy, performed either with one or two interventions. Fertility-sparing surgeries that preserved one ovary and the uterus but included all the remaining procedures were classified as complete staging. The relationship between potential risk factors and time to BOT relapse was assessed by log-rank tests corrected for multiple comparisons and Cox regression. Results Forty-six patients with a median follow-up of 5.4 years were included, of whom 91.3% had been diagnosed as FIGO stage I disease and 45.7% had received complete staging surgery. Five relapses were detected (10.9%, all of them in women who had been diagnosed with stage I disease and had received incomplete staging surgery. Log-rank tests confirmed the association between incomplete staging surgery and shorter time to BOT relapse. Conclusions Complete staging surgery should be considered a cornerstone of BOT treatment in order to minimize the risk of relapse.

    Full Text Available This was a randomized double-blinded study; in which 60 ASAI-II adult patients scheduled for major abdominal surgeries (colostomy, radical cystectomy, major gynecological surgery, and abdominal vascular surgery were received standard general anesthesia. Twenty minutes before the anticipated end of surgery, patients were randomized into two equal groups: dexmedetomidine group (group D and morphine group (group M. Group D received dexmedetomidine IV infusion 4µg/kg/h for 15 minutes (1µg/Kg followed by 0.4µg/kg/h for 3h. Group M received morphine sulfate IV (0.07mg/kg. All patients were given a morphine patient controlled analgesia (PCA pump in the post anesthesia care unit (PACU, delivering IV morphine 2mg with a lockout time of 5 minutes if pain score assessed through visual analog scale (VAS was more than 5 at any given 5-min assessment. During the PACU recovery period, morphine consumption; pain and sedation scores; hemodynamic variables (heart rate, mean arterial blood pressure, oxygen saturation and respiratory rate; and postoperative nausea, retching and vomiting (PONV were recorded every 30 min for 3h (study period by a member of staff blinded to the treatment. The study demonstrated that the use of dexmedetomidine led to significant decrease in the total amount of morphine consumed throughout the entire PACU recovery period (P0.05; significant decrease in mean arterial pressure (P0.05; without any significant changes in oxygen saturation (P<0.05 or respiratory rate (P<0.05. In conclusion, dexmedetomidine exhibited both analgesic and sedative properties. The associated cardiovascular protective pharmacological profile and the lack of respiratory depression made it potentially extremely interesting for postoperative analgesia after major abdominal surgeries.

    Major abdominal surgery may lead to a systemic inflammatory response (SIRS) with a risk of organ failure. One possible trigger for a postoperative hepatic dysfunction is an altered hepatic blood flow during SIRS, resulting in a decreased oxygen delivery. This pilot study investigated the role of liver dysfunction measured by the LiMAx test after major abdominal surgery, focussing on open and laparoscopic surgical approaches. We prospectively investigated 25 patients (7 females and 18 males, age range 55-72 years) scheduled for upper abdominal surgery. The LiMAx test, ICG-PDR and duplex sonography were carried out preoperatively, followed by postoperative days (PODs) 1, 3, 5 and 10. Laboratory parameters and clinical parameters were measured daily. Clinical outcome parameters were examined at the end of treatment. The population was divided into group A (laparotomy) versus group B (laparoscopy). LiMAx values decreased significantly on POD 1 (290 µg/kg/h, P surgery is evident and underestimated. The LiMAx test provides an adequate tool to determine liver dysfunction. Open and laparoscopic approaches appeared similar in terms of liver dysfunction and postoperative SIRS.

    Indocyanine green(ICG) kinetics(PDR/R15) used to quantitatively assess hepatic function in the perioperative period of major resective surgery and liver transplantation have been the object of an extensive, updated and critical review. New, non invasive bedside monitors(pulse dye densitometry technology) make this opportunity widely available in clinical practice. After having reviewed basic concepts of hepatic clearance, we analysed the most common indications ICG kinetic parameters have nowadays in clinical practice, focusing in particular on the diagnostic and prognostic role of PDR and R15 in the perioperative period of major liver surgery and liver transplantation. As recently pointed out, even if of extreme interest, ICG clearance parameters have still some limitations, to be considered when using these tests.

    Increased risk of bleeding after major orthopedic surgery (MOS) has been widely documented in general population. However, this complication has not been studied in elderly patients. The purpose of this study is to determine whether the risk of major bleeding after MOS is higher in elderly patients, compared with those operated at a younger age. This retrospective cohort study included total hip and total knee arthroplasty patients operated during 5 consecutive years. The main outcome was the occurrence of major bleeding. Patients with other causes of bleeding were excluded. Relative risks (RRs) and confidence intervals (CIs) were calculated, and a multivariate analysis was performed. A total of 1048 patients were included, 56% of patients were hip arthroplasties. At the time of surgery, 553 (53%) patients were older than 70 years. Patients aged >70 years showed an increased risk of major bleeding (RR: 2.42 [95% CI: 1.54-3.81]). For hip arthroplasty, the RR of bleeding was 2.61 (95%CI: 1.50-4.53) and 2.25 (95% CI: 1.03-4.94) for knee arthroplasty. After multivariate analysis, age was found to be independently associated with higher risk of major bleeding. According to European Medicines Agency criteria, patients aged ≥70 years are at a higher risk of major bleeding after MOS, result of a higher frequency of blood transfusions in this group of patients. Standardized protocols for blood transfusion in these patients are still required. Copyright © 2016 Elsevier Inc. All rights reserved.

    New designs of care in orthopaedic clinics are needed to cope with the shortage of orthopaedic surgeons and the lengthening of waiting times. To assess the effectiveness of an interdisciplinary orthopaedic clinic with a pivot nurse in the Canadian province of Quebec with regard to accessibility, quality of care, efficacy and efficiency of the clinic, and patient's quality of life. Two strategies were developed: (1) a selected cohort of new patients attending an orthopaedic service from February to September 2008 were entered into a database recording patient details, source of referral, diagnosis, satisfaction, and quality of life (36-Item Short Form Health Survey version 2). In this setting, 2 sets of questionnaires were administered to the patients: the first one during the first visit and the second one, 2 months later. A total of 243 patients from the case control were compared with 89 patients of the case study, where an interdisciplinary orthopaedic clinic with a pivot nurse has been developed; (2) costs per patient were calculated using the staff timesheets provided by the two orthopaedic clinics. The results showed a significant reduction in the waiting-list duration (accessibility) in the case study clinic owing to a strong decrease in the inappropriate consultations with the orthopaedic consultant. The quality of care remained high, and the target surgeries for total hip and knee replacement were reached, despite a strong shortage of orthopaedic doctors. Interdisciplinary orthopaedic clinic with a pivot nurse is a new approach in the province of Quebec and first results are encouraging.

    to evaluate the usefulness of bowel sounds, flatus and bowel movement presence to predict tolerance of oral intake in patients following major abdominal surgery. nutrition is one of the most important factors in the management of postoperative care. The early oral intake has shown to contribute to a faster recovery. Traditionally the beginning of postoperative feeding after major abdominal surgery is delayed until bowel sounds, flatus and/or bowel movement are present although there is no enough medical evidence for their usefulness. We studied 88 patients following major abdominal surgery. We registered the presence of bowel sounds, flatus and bowel movement each 24 hours in the postoperative period. We analized the relationship between the presence of these signs and the ability to tolerate oral intake. Predictive values, sensitivity, specificity and ROC curves were calculated. results shown that bowel sounds have an acCeptable sensibility but a very low specificity to predict the ability to tolerate oral intake. Unlike bowel sounds, bowel movements shown a low sensibility and a high specificity. Flatus turned out to have and intermediate sensitivity and specificity in the prediction of tolerance of oral feeding. in this study any of these signs were shown as a reliable indicator for beginning oral feeding because they have a moderate to low usefulness.

    Screening laboratory studies for bleeding disorders are of little predictive value for operative bleeding risk in adults. Predicting perioperative bleeding in pediatric patients is particularly difficult as younger patients often have not had significant hemostatic challenges. This issue is distinctly important for high bleeding risk surgeries, such as major spinal procedures. The aim of this study was to determine if the score of a detailed bleeding questionnaire (BQ) correlated with surgical bleeding in pediatric patients undergoing major spinal surgery. A total of 220 consecutive pediatric patients (mean age 14.2years) undergoing major spinal surgery were administered the BQ preoperatively, as well as having routine screening laboratory studies (i.e., PT, aPTT, PFA) drawn. A retrospective analysis was conducted to determine if there was a correlation between either the results of the BQ and/or laboratory studies with operative outcomes. A BQ score>2 showed a strong positive correlation with intraoperative bleeding based on both univariate and multivariate analyses. In contrast, abnormalities in screening laboratory studies showed no significant correlation with operative bleeding outcomes. Relying on screening laboratory studies alone is inadequate. The BQ used here correlated with increased intraoperative hemorrhage, suggesting this tool may be useful for assessing pediatric surgical bleeding risk, and may also be useful in identifying a subset of patients with a very low bleeding risk that may not require laboratory screening.

    Communication skills play a key role in many aspects of both medical education and clinical patient care. The objectives of this study were to identify the key components of communication skills from the perspectives of both orthopaedic residents and their program directors and to understand how these skills are currently taught. This study utilized a mixed methods design. Quantitative data were collected with use of a thirty-item questionnaire distributed to all Canadian orthopaedic residents. Qualitative data were collected through focus groups with orthopaedic residents and semistructured interviews with orthopaedic program directors. One hundred and nineteen (37%) of 325 questionnaires were completed, twelve residents participated in two focus groups, and nine of sixteen program directors from across the country were interviewed. Both program directors and residents identified communication skills as being the accurate and appropriate use of language (i.e., content skills), not how the communication was presented (i.e., process skills). Perceived barriers to effective communication included time constraints and the need to adapt to the many personalities and types of people encountered daily in the hospital. Residents rarely have explicit training in communication skills. They rely on communication training implicitly taught through observation of their preceptors and clinical experience interacting with patients, peers, and other health-care professionals. Orthopaedic residents and program directors focus on content and flexibility within communication skills as well as on the importance of being concise. They value the development of communication skills in the clinical environment through experiential learning and role modeling. Education should focus on developing residents' process skills in communication. Care should be taken to avoid large-group didactic teaching sessions, which are perceived as ineffective.

    The use of electric bicycles (E-bike) has dramatically increased. E-bikes offer convenient, environmental-friendly, and less expensive alternative to other forms of transport. However, E-bikes provide a new public health challenge in terms of safety and injury prevention. This study is the first to specifically investigate the E-bike related orthopaedic injuries, based on a national trauma registry. Data from a National Trauma Registry were reviewed for patients hospitalized following E-bike related injuries. Between Jan 2014 to Dec 2015, a total of 549 patients were reviewed. Data were analyzed according to demography, type of orthopaedic injury, associated injuries and severity, injury mechanism and treatment in the operating room. A total of 360 (65%) patients sustained orthopaedic injuries, out of them 230 (63.8%) sustained limb/pelvis/spine fractures. Lower extremity fractures were more prevalent than upper extremity fractures (p<0.001). The tibia was the most fractured bone (19.2%). Patients over the age of 50 years were at the highest risk for spine (20. 5%, p=0.0001), pelvis (15.9%, p=0.0001) and femoral neck (15.9%, p=0.0172) fractures relative to other age groups. Approximately 42% of patients sustained associated injuries, with head/neck/face injuries being the most prevalent (30.3%). followed by chest (11.9%) and abdominal injury (13.3%). A collision between E-bike and a motorized vehicle was the mechanism of injury in 35% of cases. In this mechanism of injury, patients had 1.7 times the risk for associated injuries (p<0.0001) and the risk for major trauma (ISS score ≥16) was more than the double (p=0.03). One third of patients with orthopaedic injuries required treatment in the operating room. Treatment varied depending on the type of fracture. This study provides unique information on epidemiological characteristics of orthpaedic injuries caused be E-bikes, pertinent both to medical care providers, as well as to health policy-makers allocating

    Full Text Available Anaesthesiologists are increasingly confronted with patients who had a recent coronary artery stent implanta-tion and are on dual anti-platelet medication. Non cardiac surgery and most invasive procedures increase the risk of stent thrombosis especially when procedure is performed early after stent implantation. Anaesthesiologist faces the dilemma of stopping the antiplatelet therapy before surgery to avoid bleeding versus perioperative stent thrombosis. Individualized approach should be adopted with following precautions. i In a surgical patient with a history of percu-taneous coronary intervention (PCI and coronary stent, determine the date of the procedure, the kind of the stent inserted and the possibility of complications during the procedure. ii Consider all patents with a recent stent implan-tation (e.g. less than three months for bare metal stents and less than one year for brachytherapy or drug eluting stents as high risk and consult an interventional cardiologist. iii Any decision to postpone surgery, continue, modify or discontinue antiplatelet regimes must involve the cardiologist, anaesthesiologist, surgeon, haematologist and the intensivist to balance the risk and benefit of each decision.

    Nutritional support for malnourished patients undergoing gastrointestinal surgery reduces the complication rate and shortens the length of stay. The efficacy of nutritional support after hospital discharge was analyzed in this systematic review. The search strategy (nutrition OR "enteral nutrition" OR "nutritional supplements" OR "oral nutritional supplements" OR "sip feed" OR "sip feeding" OR "dietary counseling") AND ("patient discharge" OR discharge OR postdischarge) AND (surgery OR operation OR "surgical procedure") was followed in Medline, CENTRAL, and Trip databases. Inclusion criteria comprised: type of study (randomized controlled trial), language (English, Spanish), and subjects (patients undergoing gastrointestinal surgery). The risk of bias was assessed by using the Cochrane methodology. Five studies which were published in six different articles and recruited 446 patients were included. A high risk of bias was detected for most of them. Nutritional support improved energy intake and protein intake when high-protein oral supplements were provided. The intervention was associated with better weight prognosis, but the data about body composition were inconsistent. In most of the trials, nutritional intervention did not enhance functional capacity or quality of life. None of the studies analyzed the effects on complications after discharge. Nutritional support provided at discharge may increase dietary intake and improve body weight, but the low quality of studies can weaken the validity of results.

    Patients who undergo major surgery for cancer are at high risk of postoperative sepsis. Early markers of septic complications would be useful for diagnosis and therapeutic management in patients with postoperative sepsis. The aim of this study was to investigate the association between early (first postoperative day) changes in interleukin 6 (IL-6), procalcitonin (PCT) and C-reactive protein (CRP) serum concentrations and the occurrence of subsequent septic complications after major surgery. Serial blood samples were collected from 50 consecutive patients for determination of IL-6, PCT and CRP serum levels. Blood samples were obtained on the morning of surgery and on the morning of the first postoperative day. Sixteen patients developed septic complications during the first five postoperative days (group 1), and 34 patients developed no septic complications (group 2). On day 1, PCT and IL-6 levels were significantly higher in group 1 (P-values of 0.003 and 0.006, respectively) but CRP levels were similar. An IL-6 cut-off point set at 310 pg ml(-1) yielded a sensitivity of 90% and a specificity of 58% to differentiate group 1 patients from group 2 patients. When associated with the occurrence of SIRS on day 1 these values reached 100% and 79%, respectively. A PCT cut-off point set at 1.1 ng ml(-1) yielded a sensitivity of 81% and a specificity of 72%. When associated with the occurrence of SIRS on day 1, these values reached 100% and 86%, respectively. PCT and IL-6 appear to be early markers of subsequent postoperative sepsis in patients undergoing major surgery for cancer. These findings could allow identification of postoperative septic complications.

    ABSTRACT Purpose: Immobility and pain are modifiable risk factors for development of venous thromboembolism and pulmonary morbidity after major abdominal surgery (MAS). The purpose of this study was to investigate the effect of abdominal incision support with an elasticized abdominal binder on postoperative walk performance (mobility), perceived distress, pain, and pulmonary function in patients following MAS. Methods: Seventy-five patients scheduled to undergo MAS via laparotomy were randomized to experimental (binder) or control (no binder) groups. Sixty (33 male, 27 female; mean age 58±14.9 years) completed the study. Preoperative measurements of 6-minute walk test (6MWT) distance, perceived distress, pain, and pulmonary function were repeated 1, 3, and 5 days after surgery. Results: Surgery was associated with marked postoperative reductions (p<0.001) in walk distance (∼75–78%, day 3) and forced vital capacity (35%, all days) for both groups. Improved 6MWT distance by day 5 was greater (p<0.05) for patients wearing a binder (80%) than for the control group (48%). Pain and symptom-associated distress remained unchanged following surgery with binder usage, increasing significantly (p<0.05) only in the no binder group. Conclusion: Elasticized abdominal binders provide a non-invasive intervention for enhancing recovery of walk performance, controlling pain and distress, and improving patients' experience following MAS.

    In the last decade, major advances in venous thromboembolism (VTE) prophylaxis in orthopaedic surgery have included the development of new anticoagulants that are poised to replace low molecular weight heparins (LMWHs) and improvements in operative and perioperative care that have likely led to a decline in the rates of symptomatic VTE and mortality independent of anticoagulant use. A systematic review of the literature was performed to identify phase III randomized controlled trials of VTE prevention that compared new anticoagulants (fondaparinux, rivaroxaban, dabigatran, apixaban) with LMWH (enoxaparin) in major elective orthopaedic surgery. Our aims were to obtain best estimates of the rates of patient important events (symptomatic VTE, mortality, and bleeding) in contemporary trials of VTE prevention, and to consider the implications of these contemporary rates for clinical practice and future research. Fourteen studies, which enrolled 40,285 patients, were included in the analyses. The combined median rates (ranges) for all five anticoagulants for symptomatic VTE and mortality to the end of follow-up were 0.99 % (0.15-2.58 %) and 0.26 % (0-0.92 %) respectively, whereas the median rate (range) of clinically important bleeding was 3.44 % (2.25-7.74 %). In contemporary trials of anticoagulants, the rates of symptomatic VTE and mortality are low, but the rates of clinically important post-operative bleeding remain relatively high. Based on these results, we propose that approaches that minimize bleeding without substantially reducing efficacy merit investigation, particularly if improvement in surgical and perioperative care have also resulted in falling baseline patient important VTE rates independent of anticoagulant use.

    Post operative surgical site infection following implant surgery is a major problem in orthopedic surgical practice. Infection occurring after internal fixation of a fracture is a devastating complication and may be difficult to treat. The frequency of occurrence of surgical site infection has decreased with improvements in aseptic technique. The objectives of the study are to determine the incidence of surgical site infection following orthopaedic related implant surgeries and to indentify the predisposing factors. The study was a prospective study conducted at the National orthopedic hospital, Enugu. Wound surveillance was carried out for the 97 patients included in this study for a period of 6 months postoperatively. The diagnosis of surgical site infection was in accordance with the CDC's guideline for prevention of surgical site infection published in 1999. The study included 61 males and 36 females giving a ratio of 1.7:1. The study population was aged 7 to 83 years with a mean age of 38.7 +/- 18.3 years. The infection rate was found to be 9.3% with staphylococcus aureus as the most common causative organism in 55.6% of cases. Two of the nine infected cases required implant removal. Significant factor was a theatre population of more than 6 persons. Surgical site infection following implant surgery is relatively common in our environment with staphylococcus aureus as the major causative organism. Increased theatre populations increase the risk of implant associated surgical site infection.

    Musculoskeletal ultrasound (MSK-US) is a quick and effective imaging tool that can be utilized by orthopaedic surgeons to identify common musculoskeletal pathology such as ankle tendinopathy. This study evaluated the ability of 15 orthopaedic surgery residents to identify and measure ankle tendons after attending a multimedia tutorial on MSK-US. Afterwards, proficiency of usage was assessed by identification and quantification of three ankle tendons (Achilles, tibialis posterior, and flexor hallucis longus) in a cadaver limb. Resident comfort level and plan for future use were also assessed. After completing the tutorial, accuracy measuring the Achilles, tibialis posterior, and flexor hallucis longus tendons was 94.8%, 90.2%, and 90.1%, respectively. Resident comfort level improved from a level of 2.3 before the tutorial to 6.8 afterwards. Seventy-one percent of residents plan to use ultrasound in clinical practice. These results show that orthopaedic surgery residents can identify and assess tendon size via MSK-US with sufficient accuracy after a multimedia tutorial.

    Current theatre practice and protocol involves the use of pressure sore prevention pads in the positioning and support of all patients undergoing orthopaedic surgery. Microbiological swabs were taken from those pads placed adjacent to the operative field immediately before implant surgery. Eleven out of the 13 pads sampled yielded bacterial growth capable of causing deep-seated infection. The transfer of these pads between the designated orthopaedic theatres and the rest of the theatre complex was also noted. We recommend that the use of these pads should be closely reviewed. They should either be used with stricter guidelines for decontamination between use or disposable 'clean' alternatives sought.

    While deep vein thrombosis (DVT) may be clinically suspected at several time points after major orthopedic surgery, clinical examination is often unreliable, and compression ultrasonography (CUS) screening at discharge is of limited value. A prospective cohort study was carried out in 1,033 consecutive patients who had undergone major hip or knee surgery, aimed to assess the accuracy of a strategy consisting of clinical investigation followed by CUS in the detection of proximal DVT before discharge. The circumferences of both legs were measured in all patients; those exhibiting >2 cm difference between them were considered to have suspected DVT, and underwent bilateral CUS. The same diagnostic workup was repeated on days 45 and 90 after surgery. Three patients developed pulmonary embolism (PE) during admission (one died). Five additional patients died before discharge. Routine clinical evaluation before discharge was done in 1,025 patients, and 105 (10%) had suspected DVT. CUS confirmed the diagnosis in 24 (2.3% of the overall series). After discharge, 59 patients had suspected DVT on day 45, 53 on day 90. DVT diagnosis was confirmed by CUS in 27 (26%). Three additional patients developed PE (1 fatal). This translates into a sensitivity of the routine examinations at discharge of 44%. A limited diagnostic workup for DVT before discharge has the capacity to identify 44% of those patients who will become symptomatic afterwards.

    Deep vein thrombosis (DVT) is a prevalent problem for orthopedic patients, particularly owing to the nature of operative interventions and treatment procedures, predisposing to an high risk of DVT. This descriptive study was conducted to determine the levels of risk, the risk factors, and their odds ratio for DVT in patients undergoing major orthopedic surgery. Data were collected using a Patient Information Form and the Autar DVT Risk Assessment Scale (DVTRAS) in orthopedic wards of a university hospital on postoperative day 2. Data were analyzed using descriptive, comparative analysis, and binary logistic regression. The 102 patients (mean age, 52.58 ± 21.58 years) were hospitalized for a mean of 14.35 ± 14.56. Of the sample, 53.9% were female, 65.7% had a history of previous surgery, and 54.9% had undergone total hip/knee arthroplastic surgery, 67.6% of patients wore graduated compression stockings, and 62.7% were administered liquid infusion. Those patients had moderate risk score (12.77 ± 5.66) in the Autar DVTRAS. According to binary logistic regression analysis, aging, obesity, immobility, and acute and chronic diseases were significant risk factors for postoperative DVT (p ≤ .05). This study highlights evidence on the degree of DVT risk, risk factors, and impact of venous thromboembolism in patients undergoing major orthopedic operations. For evidence-based clinical practice, these high-level risk factors should be taken into account in the prevention of DVT in orthopedic patients.

    This study examined the relationship between pre-operative nutritional status and systemic inflammatory response syndrome (SIRS) or sepsis following major vascular surgery. Subjects undergoing open AAA repair, EVAR or lower limb revascularisation were studied prospectively. Pre-operative nutrition was assessed clinically using Mini-Nutritional Assessment (MNA) and body composition was measured by dual energy X-ray absorptiometry (DEXA) scanning. SIRS severity was assessed for 5 post-operative days and sepsis noted within 30 days of surgery. Using MNA, neither SIRS severity nor sepsis occurrence differed significantly between 'well-nourished' subjects and those 'at risk of malnutrition'. Using DEXA, negative associations existed between body mass index and both SIRS score and SIRS duration. Fat free mass (FFM) was negatively associated with SIRS score and duration. Negative associations also existed between skeletal muscle mass (SMM) and SIRS score and duration. SMM was also negatively correlated with post-operative length of stay in hospital. There were no significant correlations between sepsis and any nutritional indices. Lower pre-operative nutritional indices, indicating protein energy malnutrition, were associated with more severe systemic inflammatory responses following major vascular surgery.

    Auscultation for bowel sounds has been advocated by some clinicians as a method to determine the resolution of postoperative ileus. Our primary aim was to prospectively evaluate the relationships between bowel sounds and the ability to tolerate oral intake in patients after major abdominal surgery. Secondarily we aimed to evaluate relationships among bowel sounds, flatus and bowel movement, and oral intake. This was a prospective, blinded observational study. The study was conducted at Western Pennsylvania Hospital. A total of 124 adult patients undergoing major abdominal surgery were included. Data were collected by medical students blinded to the purpose of the study for 10 days postoperatively or until discharge, including the presence of bowel sounds (auscultation for 1 minute), flatus, bowel movement, and tolerance of oral intake (defined as ingestion of ≥1000 mL/24 h and each subsequent day without vomiting). Associations between paired variables were determined using ϕ coefficient testing. The study population consisted of 51 men and 73 women, with a mean age of 64 years (range, 20-92 y). The majority of patients (78/124 (63%)) underwent colorectal resection. The median length of hospital was 6 days. Bowel sounds were not associated with flatus, bowel movement, or tolerance of oral intake throughout the study period. The positive predictive value of bowel sounds in predicting flatus and bowel movement was low in the early postoperative period and remained Flatus correlated with bowel movement in the first 6 days postoperation, but neither flatus nor bowel movement was associated with tolerance of oral intake. The rate of tolerance of oral intake was relatively modest throughout the study period. Bowel sounds are not associated with flatus, bowel movement, or tolerance of oral intake after major abdominal surgery.

    ➤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 <400 cells/mm(3).➤With regard to trauma surgery, the rates of early and late infection around implants, as well as union rates, are comparable with those in the HIV-negative population; however, there is an increased risk of pulmonary, renal, and infectious or septic complications in the polytrauma setting.➤Factors such as CD4 count, 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.

    To study innate immune pathways in patients undergoing hepatopancreaticobiliary surgery to understand mechanisms leading to enhanced inflammatory responses and identifying biomarkers of adverse clinical consequences. Patients undergoing major abdominal surgery are at risk of life-threatening systemic inflammatory response syndrome (SIRS) and sepsis. Early identification of at-risk patients would allow tailored postoperative care and improve survival. Two separate cohorts of patients undergoing major hepatopancreaticobiliary surgery were studied (combined n = 69). Bloods were taken preoperatively, on day 1 and day 2 postoperatively. Peripheral blood mononuclear cells and serum were separated and immune phenotype and function assessed ex vivo. Early innate immune dysfunction was evident in 12 patients who subsequently developed SIRS (postoperative day 6) compared with 27 who did not, when no clinical evidence of SIRS was apparent (preoperatively or days 1 and 2). Serum interleukin (IL)-6 concentration and monocyte Toll-like receptor (TLR)/NF-κB/IL-6 functional pathways were significantly upregulated and overactive in patients who developed SIRS (P SIRS. Increased TLR4 and TLR5 gene expression in whole blood was demonstrated in a separate validation cohort of 30 patients undergoing similar surgery. Expression of TLR4/5 on monocytes, particularly intermediate CD14CD16 monocytes, on day 1 or 2 predicted SIRS with accuracy 0.89 to 1.0 (areas under receiver operator curves). These data demonstrate the mechanism for IL-6 overproduction in patients who develop postoperative SIRS and identify markers that predict patients at risk of SIRS 5 days before the onset of clinical signs.

    Enhanced Recovery After Surgery (ERAS) programmes aim at an early recovery after surgical trauma and consequently at a reduced length of hospitalisation. This paper presents the protocol for a study that focuses on large-scale implementation of the ERAS programme in major gynaecological surgery in the Netherlands. The trial will evaluate effectiveness and costs of a stepped implementation approach that is characterised by tailoring the intensity of implementation activities to the needs of organisations and local barriers for change, in comparison with the generic breakthrough strategy that is usually applied in large-scale improvement projects in the Netherlands. All Dutch hospitals authorised to perform major abdominal surgery in gynaecological oncology patients are eligible for inclusion in this cluster randomised controlled trial. The hospitals that already fully implemented the ERAS programme in their local perioperative management or those who predominantly admit gynaecological surgery patients to an external hospital replacement care facility will be excluded. Cluster randomisation will be applied at the hospital level and will be stratified based on tertiary status. Hospitals will be randomly assigned to the stepped implementation strategy or the breakthrough strategy. The control group will receive the traditional breakthrough strategy with three educational sessions and the use of plan-do-study-act cycles for planning and executing local improvement activities. The intervention group will receive an innovative stepped strategy comprising four levels of intensity of support. Implementation starts with generic low-cost activities and may build up to the highest level of tailored and labour-intensive activities. The decision for a stepwise increase in intensive support will be based on the success of implementation so far. Both implementation strategies will be completed within 1 year and evaluated on effect, process, and cost-effectiveness. The primary

  19. Clinical assessment of peripheral perfusion to predict postoperative complications after major abdominal surgery early: a prospective observational study in adults

    2014-01-01

    Introduction Altered peripheral perfusion is strongly associated with poor outcome in critically ill patients. We wanted to determine whether repeated assessments of peripheral perfusion during the days following surgery could help to early identify patients that are more likely to develop postoperative complications. Methods Haemodynamic measurements and peripheral perfusion parameters were collected one day prior to surgery, directly after surgery (D0) and on the first (D1), second (D2) and third (D3) postoperative days. Peripheral perfusion assessment consisted of capillary refill time (CRT), peripheral perfusion index (PPI) and forearm-to-fingertip skin temperature gradient (Tskin-diff). Generalized linear mixed models were used to predict severe complications within ten days after surgery based on Clavien-Dindo classification. Results We prospectively followed 137 consecutive patients, from among whom 111 were included in the analysis. Severe complications were observed in 19 patients (17.0%). Postoperatively, peripheral perfusion parameters were significantly altered in patients who subsequently developed severe complications compared to those who did not, and these parameters persisted over time. CRT was altered at D0, and PPI and Tskin-diff were altered on D1 and D2, respectively. Among the different peripheral perfusion parameters, the diagnostic accuracy in predicting severe postoperative complications was highest for CRT on D2 (area under the receiver operating characteristic curve = 0.91 (95% confidence interval (CI) = 0.83 to 0.92)) with a sensitivity of 0.79 (95% CI = 0.54 to 0.94) and a specificity of 0.93 (95% CI = 0.86 to 0.97). Generalized mixed-model analysis demonstrated that abnormal peripheral perfusion on D2 and D3 was an independent predictor of severe postoperative complications (D2 odds ratio (OR) = 8.4, 95% CI = 2.7 to 25.9; D2 OR = 6.4, 95% CI = 2.1 to 19.6).

    The Federal Government, the largest payer of health care, considers readmission within 30 days of discharge an indicator of quality of care. Many studies have focused on causes for and strategies to reduce readmissions following medical admissions. However, few studies have focused on the differences between them. We believe that the causes for readmission following orthopaedic surgery are markedly different than those following medical admissions, and therefore, the strategies developed to reduce medical readmissions will not be as effective in reducing readmissions after elective orthopaedic surgery. All unplanned 30-day readmissions following an index hospitalization for an elective orthopaedic procedure (primary and revision total joint arthroplasty and spine procedure) or for one of the three publicly reported medical conditions (AMI, HF, and pneumonia, which accounted for 11% of readmissions) were identified at our institution from 2010 through 2012. A total of 268 patients and 390 medical patients were identified as having an unplanned 30-day readmission. We reviewed a prospectively collected data base to determine the reason for readmission in each encounter. A total of 233 (86.9%) orthopaedic patients were readmitted for surgical complications, most commonly for a wound infection (56.0%) or wound complication (11.6%). Following an index admission of HF or AMI, the primary reason for readmission was a disease of the circulatory system (55.9% and 57.4%, respectively). Following an index admission for pneumonia, the primary reason for readmission was a disease of the respiratory system (34.5%). The causes of readmissions following orthopaedic surgery and medical admissions are different. Patients undergoing orthopaedic procedures are readmitted for surgical complications, frequently unrelated to aftercare, and medicine patients are readmitted for reasons related to the index diagnosis. Interventions designed to reduce orthopaedic readmissions must focus on

    The transition into practice following a fellowship in pediatric orthopaedics is challenging. This study seeks to describe the first-year experiences of 5 pediatric orthopaedists. An Institutional Review Board-approved retrospective review was conducted of 5 pediatric orthopaedic surgeons' first year in practice. All were fellowship trained and practiced at private or academic subspecialty groups. Clinical volume, payor mix, surgical cases, as well as complications were evaluated. A total of 1172 surgical procedures were available for review. Surgeons performed an average of 234 cases with a mean case load of 19.5 procedures per month. Fracture care and surgical management of infection represented the largest number of procedures. 42.3% of patients were covered by government insurance or were uninsured. Surgeons saw an average of 30.5 new patients per week in clinic. Of these, 10.7% of patients were scheduled for an elective surgical case. A sample of clinical practice revealed that 41.3% of patients were covered by government or no insurance. 17.8% of surgical patients sustained a complication with the majority being minor or expected. 18.8% of complications were major and required repeat operation. Complications peaked in the fourth month of practice. Although clinical and surgical volumes can vary during the first year of practice, fracture care and surgical management of infection represent the majority of operative cases. A large portion of surgical volume results from emergent care, whereas elective cases are more elusive with only 1 in 10 elective patients resulting in surgical treatment. Despite a significant number of untoward events related to surgery, major surgical complications are uncommon in the first year of practice. The majority of surgical cases in the first year of practice are due to trauma and infection. A high volume of patients must be seen to establish a practice, particularly given the high rate of Medicaid patients. These figures provide

    2015-12-01

    Leaks are the most frequent early postoperative complication in the two most popular bariatric procedures, Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy. Multimodal therapy based on self-expandable stent insertion 'to cover' the defect is the most widely documented technique to date with a reported success rate >80%. Additional experimental techniques 'to close' the defect or 'to drain' the paradigestive cavity have been reported with encouraging results. The role of endoscopy in early postoperative bleeding is limited to management of bleeds arising from fresh sutures and the diagnosis of chronic sources of bleeding such as marginal ulcer after RYGB. Post-RYGB stricture is a more delayed complication than leaks and the role of endoscopic dilation as a first-line treatment in this indication is well documented. Ring and band placement are outdated procedures for obesity treatment, but might still be an indication for endoscopic removal, a technique which does not compromise further surgery, if needed.

The aim of this meta-analysis is to compare the efficacy of epidural analgesia (EA and intravenous patient-controlled analgesia (IV-PCA following major spine surgery. We searched electronic databases, including the PubMed, EMBASE, Ovid and Cochrane databases, for randomized controlled trials (RCTs published before June 2016. The quality of the included trials was assessed using the Cochrane risk-of-bias tool. Random effects models were used to estimate the standardized mean differences (SMDs and relative risks (RRs, with the corresponding 95% confidence intervals (CI. Subgroup analyses stratified by the type of epidural-infused medication and epidural delivery were also performed. A total of 17 trials matched the inclusion criteria and were chosen for the following meta-analysis. Overall, EA provided significantly superior analgesia, higher patient satisfaction and decreased overall opioid consumption compared with IV-PCA following major spine surgery. Additionally, no differences were found in the side effects associated with these two methods of analgesia. Egger’s and Begg’s tests showed no significant publication bias. We suggest that EA is superior to IV-PCA for pain management after major spine surgery. More large-scale, high-quality trials are needed to verify these findings.

    Orthopaedic shoes are individually handmade after a prescription from an orthopaedic surgeon, hence relatively expensive. Bad compliance is mentioned in the literature but not investigated. In order to evaluate patient compliance and the effect of orthopaedic shoes, 85 patients who were prescribed...... orthopaedic shoes at the authors' department during a 3 year period received a questionnaire concerning relief of symptoms and daily use of the shoes. The answers from 74 patients were correlated to the prescription procedure and the degree of medical follow-up. Only 60 of 74 patients used their shoes. Some...... were checked by the orthopaedic surgeon after delivery of the shoes. In conclusion the authors believe there is a great need for information to be given to the patients about the functions and limitations of orthopaedic shoes and that every patient should be offered a control check-up by the surgeon...

    A disaster is a catastrophic event that disrupts normal infrastructure to such a degree that normal response mechanisms and capabilities cannot manage what is required to respond appropriately to the event. Launched after the largest urban disaster in modern history--the 2010 Haiti Earthquake--the American Academy of Orthopaedic Surgeons/Society of Military Orthopaedic Surgeons/Orthopaedic Trauma Association/Pediatric Orthopaedic Association of North America (AAOS/SOMOS/OTA/POSNA) Disaster Response Course (DRC) is designed to prepare orthopaedic surgeons for service in disaster response and humanitarian assistance efforts in both the acute phases as well as in the recovery and reconstructions phases. To date, 395 orthopaedic surgeons have completed the DRC and 286 (72.4%) have opted to become registered disaster responders.

    Internet searches and social media utilization in health care has exploded over the past 5 years, and patients utilize it to gain information on their health conditions and physicians. Social media has the potential to serve as a means for education, communication, and marketing in all health care specialties. Physicians are sometimes reluctant to engage because of concerns of privacy, litigation, and lack of experience with this modality. Many surgical subspecialties have capitalized on social media but no study to date has examined the specific footprint of pediatric orthopaedic surgeons in this realm. We aim to quantify the utilization of individual social media platforms by pediatric orthopaedic surgeons, and identify any differences between private and hospital-based physicians, but also regional differences. Using the Pediatric Orthopaedic Society of North America Member Directory, each active member's social media presence was reviewed through an Internet search. Members were stratified on the basis of practice model and geographic location. Individual Internet searches, social media sites, and number of publications were reviewed for social media presence. Of 987 Pediatric Orthopaedic Society of North America members, 95% had a professional webpage, 14.8% a professional Facebook page, 2.2% a professional Twitter page, 36.8% a LinkedIn profile, 25.8% a ResearchGate profile, 33% at least 1 YouTube. Hospital-based physicians had a lower mean level of utilization of social media compared with their private practice peers, and a higher incidence of Pubmed publications. Private practice physicians had double the social media utilization. Regional differences reveal that practicing Pediatric Orthopaedists in the Northeast had increased utilization of ResearchGate and LinkedIn and the West had the lowest mean social media utilization levels. The rapid expansion of social media usage by patients and their family members is an undeniable force affecting the health

    Enhanced recovery pathways have been increasingly adopted into surgical specialties with the aim of reducing the stress response and improving the metabolic response to surgical insult. Enhanced recovery pathways encompass a large range of perioperative elements that together aim to restore a patient's gut function, mobility, function and well-being to preoperative levels as soon as feasible after major surgery. There is increasing evidence that rapid recovery and return to normal function reduces complications. This may not just have a benefit by reducing morbidity and mortality but also have an effect on long-term survival. There also may be additional benefits for patients with cancer.

  9. Perioperative lung-protective ventilation strategy reduces postoperative pulmonary complications in patients undergoing thoracic and major abdominal surgery

    Science.gov (United States)

    2016-01-01

    The occurrence of postoperative pulmonary complications is strongly associated with increased hospital mortality and prolonged postoperative hospital stays. Although protective lung ventilation is commonly used in the intensive care unit, low tidal volume ventilation in the operating room is not a routine strategy. Low tidal volume ventilation, moderate positive end-expiratory pressure, and repeated recruitment maneuvers, particularly for high-risk patients undergoing major abdominal surgery, can reduce postoperative pulmonary complications. Facilitating perioperative bundle care by combining prophylactic and postoperative positive-pressure ventilation with intraoperative lung-protective ventilation may be helpful to reduce postoperative pulmonary complications.

    Full Text Available Abstract For head and neck as well as for oromaxillofacial surgery, the use of the pectoralis major myocutaneous (PMMC flap is a standard reconstructive technique after radical surgery for cancers in this region. We report to our knowledge for the first development of breast cancer in the PMMC flap in a 79 year old patient, who had undergone several operations in the past for recurring squamous cell carcinoma of the jaw. The occurrence of a secondary malignancy within the donor tissue after flap transfer is rare, but especially in the case of transferred breast tissue and the currently high incidence of breast cancer theoretically possible. Therefore preoperative screening mammography seems advisable to exclude a preexisting breast cancer in female patients undergoing such reconstruction surgery. Therapy for breast cancer under these circumstances is individual and consists of radical tumor resection followed by radiation if applicable and a standard systemic therapeutic regimen on the background of the patients individual prognosis due to the primary cancer.

  14. Stellate ganglion blockade for analgesia following upper limb surgery.

    LENUS (Irish Health Repository)

    McDonnell, J G

    2012-01-31

    We report the successful use of a stellate ganglion block as part of a multi-modal postoperative analgesic regimen. Four patients scheduled for orthopaedic surgery following upper limb trauma underwent blockade of the stellate ganglion pre-operatively under ultrasound guidance. Patients reported excellent postoperative analgesia, with postoperative VAS pain scores between 0 and 2, and consumption of morphine in the first 24 h ranging from 0 to 14 mg. While these are preliminary findings, and must be confirmed in a clinical trial, they highlight the potential for stellate ganglion blockade to provide analgesia following major upper limb surgery.

    AIM: To evaluate the surface expression of triggering receptor on myeloid cell 1 (TREM-1), class Ⅱ major histocompatibility complex molecules (HLA-DR), andthe expression of the splicing variant (svTREM-1) ofTREM-1 in septic patients and those subjected to major abdominal surgery.METHODS: Using flow cytometry, we examined the surface expression of TREM-1 and HLA-DR in peripheral blood monocytes from 11 septic patients, 7 elective gastrointestinal surgical patients, and 10 healthy volunteers. svTREM-1 levels were analyzed by RT-PCR. RESULTS: Basal expression of TREM-1 and HLA-DR in healthy volunteers was 35.91±14.75 MFI and75.8±18.3%, respectively. In septic patients, TREM-1 expression was 59.9±23.9 MFI and HLA-DR expression was 44.39±20.25%, with a significant differencebetween healthy and septic groups (P<0.05) for bothmolecules. In the surgical patients, TREM-1 and HLA-DR expressions were 56.8±20.85 MFI and 71±13.8% before surgery and 72.65±29.92 MlFI and 72.82±22.55% after surgery. TREM-1 expression was significantly different(P = 0.0087) between the samples before and aftersurgery and svTREM-1 expression was 0.8590±0.1451 MF1, 0.8820±0.1460 MF1, and 2.210±0.7873MF1 in the healthy, surgical (after surgery) and septic groups, respectively. There was a significant difference (P = 0.048) in svTREM-1 expression between the healthy and surgical groups and the septic group.CONCLUSION: TREM-1 expression is increased during systemic inflammatory conditions such as sepsis and the postoperative phase. Simultaneous low expression of HLA-DR molecules correlates with the severity of illness and increases susceptibility to infection. Additionally, TREM-1 expression is distinctly different in surgical patients at different stages of the inflammatory response before and after surgery. Thus, surface TREM-1 appears to be an endogenous signal during the course of the inflammatory response. svTREM-1 expression is significantly increased during sepsis, appearing to be

    In order to investigate the epidemiology and features of Blount disease in Japan, the Japanese Pediatric Orthopaedic Association conducted a multicenter study on Blount disease in 2003. Questionnaires were sent to 1,350 training hospitals of the Japanese Orthopaedic Association. This study included those with stage I or II diagnosed between 1990 and 2002 and those with stage III or higher diagnosed between 1980 and 2002 based on the Langenskiöld classification. The questionnaire items included age at diagnosis, sex, presence or absence of a family history of bowlegs, past history of trauma, birthplace, age when starting to walk, height and weight at the initial presentation, laterality of the affected knee, disease types (infantile or adolescent), treatments, and plain radiographic findings. The results for 212 patients with 296 affected knees were obtained. The disease types were infantile in 190 patients with 270 affected knees and adolescent in 22 patients with 26 affected knees. There were more girls among cases with both types. Among the infantile-type cases, there were more patients with bilaterally affected knees; however, in the adolescent-type cases, there were more patients with unilaterally affected knees. Patients with either type tended to be obese at diagnosis. There was little difference in age at which patients with either type started to walk, compared with the mean age for the general population. Conservative treatment was applied to most infantile-type cases in stage I or II, whereas surgery was performed in all but one of those with stage III or IV of the disease. Most adolescent-type cases underwent surgery. This was the first multicenter study on Blount disease in Japan. Among 296 knees, the majority of these knees had stage I or II Blount disease. Very few cases had stage III or higher disease, and there were 35 knees with the infantile type and 19 with the adolescent type in the 23 years from 1980 through 2002.

  18. May Renal Resistive Index Be an Early Predictive Tool of Postoperative Complications in Major Surgery? Preliminary Results

    Directory of Open Access Journals (Sweden)

    Enrico Giustiniano

    2014-01-01

    Full Text Available Background. Patients who undergo high-risk surgery represent a large amount of post-operative ICU-admissions. These patients are at high risk of experiencing postoperative complications. Renal Resistive Index was found to be related with renal dysfunction, hypertension, and posttraumatic hemorrhagic shock, probably due to vasoconstriction. We explored whether Renal Resistive Index (RRI, measured after awakening from general anesthesia, could have any relationship with postoperative complications. Methods. In our observational, stratified dual-center trial, we enrolled patients who underwent general anesthesia for high-risk major surgery. After awakening in recovery room (or during awakening period in subjects submitted to cardiac surgery we measured RRI by echo-color-Doppler method. Primary endpoint was the association of altered RRI (>0.70 and outcome during the first postoperative week. Results. 205 patients were enrolled: 60 (29.3% showed RRI > 0.70. The total rate of adverse event was 27 (18.6% in RRI ≤ 0.7 group and 19 (31.7% in RRI > 0.7 group (P=0.042. Significant correlation between RRI > 0.70 and complications resulted in pneumonia (P=0.016, septic shock (P=0.003, and acute renal failure (P=0.001 subgroups. Patients with RRI > 0.7 showed longer ICU stay (P=0.001 and lasting of mechanical ventilation (P=0.004. These results were confirmed in cardiothoracic surgery subgroup. RRI > 0.7 duplicates triplicates the risk of complications, both in general (OR 2.03 93 95% CI 1.02–4.02, P=0.044 and in cardiothoracic (OR 2.62 95% CI 1.11–6.16, P=0.027 population.

    With the purpose of decreasing the existing variability in the criteria of preoperative evaluation and facilitating the clinical decision-making process, our hospital has a protocol of preoperative tests to use with ASA I and ASA II patients. The aim of the study was to calculate the economic impact caused by clinicians' non-adherence to the protocol for the anaesthesiological evaluation of ASA 1 and ASA II patients. A retrospective study of costs with a random sample of 353 patients that were seen in the consultation for Anesthesiology over a period of one year. Aspects related to the costs, patient's profiles and specialties were analysed, according to the degree of fulfillment of the protocol. The lack of adherence to the the protocol was 70%. 130 chest X-rays and 218 ECG were performed without indication. This generated an excess costs of 34 € per patient. Taking into account the expenses of both tests and the attended population undergoing ambulatory surgery during the one-year period, an excess spending for the hospital of between 69.164 € and 83.312 € was estimated. Clinical variability should be reduced and the creation of synergies between the different departments should be enhanced in order to adjust the request for unnecessary complementary tests to decrease health care and to improve the quality of patient care.

    Systemic inflammatory response syndrome (SIRS) includes a number of pathologic states because of its loose definition. This study assessed differences in metabolic and circulatory host responses in various patients with SIRS perioperatively. Fifty-four patients who underwent abdominal surgeries [gastric resection (n=20), colorectal resection (n=24), hepatic resection (n=8)] were divided into two groups: Group A; SIRS (+) on 1 postoperative day (POD), (n=29), B; SIRS (-) on 1 POD, (n=25). The other eight non-operated patients with SIRS caused by infection were enrolled in Group C, as common SIRS. Indirect calorimetry, body impedance measurement to assess water compartments and pulse dye-densitometry for hemodynamic examination were performed in subjects until 14 POD. The ratio of energy expenditure to basal energy expenditure (%REE) was significantly increased postoperatively, and there were significant differences on %REE from 3 POD to 14 POD between groups A and B. However, %REE in group C was 162+/-23%, which was significantly increased compared with that at 1 POD of groups A (130 +/- 17%) and B (125+/-18%). Cardiac output in group A showed a significant increase until 3 POD compared with that in group B but was significantly lower than that in group C. Subjects with common SIRS caused by infection were significantly more hypermetabolic than subjects with postoperative SIRS. Adequate energy intake and circulatory management should be cautiously determined according to the severity of SIRS.

    2015-05-01

    The call for evidence-based knowledge in clinical nursing practice has increased during recent decades and research in orthopaedic nursing is needed to improve patients' conditions, care and treatment. A descriptive cross-sectional survey was conducted to determine the self-perceived theoretical knowledge and practical research competencies among orthopaedic nurses and their interest and motivation to increase these in everyday practice. A newly developed questionnaire was given to a convenience sample of 87 orthopaedic nurses. Forty three orthopaedic nurses (49.4%) completed the questionnaire. The results indicated that despite the majority of orthopaedic nurses having low self-perceived theoretical knowledge and practical research competencies, their interest and motivation to improve these were high, especially their inner motivation. However, the nurses' inner motivation was inhibited by a lack of acceptance from colleagues and section head nurses and a shortage of time. This study forms a baseline as a part of a larger study and contributes knowledge useful to other orthopaedic departments with an interest in optimizing nursing research to improve orthopaedic nursing care quality.

    2016-05-01

    Improvements in laparoscopic surgery have led to the introduction of laparoendoscopic single-site surgery (LESS) as an alternative to conventional laparoscopy conferring a number of possible advantages. In this review, we aim to elucidate the aspects of LESS for major urological procedures in the pediatric population. An in-depth search of the literature was performed in the databases of PubMed and Scopus, for studies investigating the technical aspects and clinical outcomes of partial nephrectomies, nephrectomies, nephroureterectomies, varicocelectomies and pyeloplasties in children. Data on parameters such as operation time, instrumentation, perioperative complications, hospital stay and follow up period were collected and further analyzed cumulatively. Twenty nine studies met the inclusion criteria incorporating 386 patients who underwent 401 procedures. There were no major intraoperative complications, with only 19 patients (4.73%) facing postoperative complications. No perioperative deaths were reported. In the hands of experienced surgeons LESS seems a feasible, efficient and less invasive alternative to standard laparoscopy in the field of pediatric urology. There is an eminent need of well-designed randomized controlled trials comparing the two techniques. Copyright © 2016 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

    2016-10-01

    To assess preferences of health care workers (HCWs) and parents of term and preterm infants to adverse health outcomes, and how perceived surgical mortality influences decision-making. A total of 536 participants (157 HCWs, 201 parents of term infants, and 178 parents of preterm infants) were recruited to take part in a structured interview. Preferences related to treatment of a critically ill preterm infant with necrotizing enterocolitis were measured by health state rank permutation analysis and pivotal risk analysis. Between-group and subgroup comparisons were performed. HCWs rank adverse health states less favorably than parents of preterm infants, consistently ranking 2 of the most adverse health states worse than death. Pivotal risk values of HCWs for all health states were consistently the lowest of the 3 groups. High operative mortality was associated uniformly with reduction in pivotal risks for all groups both in favorable and adverse health states. Subgroup analyses revealed significant discrepancies in preferences between fathers and mothers as well as doctors and nurses. Regular religious practice was significantly associated with increased pivotal risks in parental subgroups. As discrepancies in health state preferences existed between subgroups (ie, doctors vs nurses, mothers vs fathers) and perceived operative mortality consistently biased parental and HCW health state preferences, we recommend that HCWs should first identify differences regarding patient management before interviewing the parents together. HCWs should be aware of inadvertently biasing parents when discussing the risks and outcomes of surgery in conjunction with the overall long-term prognosis of the underlying condition.

    Patients are seeking out medical information on the Internet and utilizing smartphone health applications ("apps"). Smartphone use has exponentially increased among orthopaedic surgeons and patients. Despite this increase, patients are rarely directed to specific apps by physicians. No study exists querying patient preferences for a patient-centered, orthopaedic smartphone application. The purpose of this study is to 1) determine Internet use patterns amongst orthopaedic patients; 2) ascertain access to and use of smartphones; and 3) elucidate what features orthopaedic patients find most important in a smartphone application. We surveyed patients in an orthopaedic practice in an urban academic center to assess demographics, access to and patterns of Internet and Smartphone use, and preferences for features in a smartphone app. A total of 310 surveys were completed. Eighty percent of patients reported Internet access, and 62% used the Internet for health information. Seventy-seven percent owned smartphones, 45% used them for health information, and 28% owned health apps. Only 11% were referred to an app by a physician. The highest ranked features were appointment reminders, ability to view test results, communication with physicians, and discharge instructions. General orthopaedic information and pictures or videos explaining surgery were the 2 lowest ranked features. Seventy-one percent of patients felt an app with some of the described features would improve their healthcare experiences, and 40% would pay for the app. The smartphone is an under-utilized tool to enhance patient-physician communication, increase satisfaction, and improve quality of care. Patients were enthusiastic about app features that are often included in patient health portals, but ranked orthopaedic educational features lowest. Further study is required to elucidate how best to use orthopaedic apps as physician-directed educational opportunities to promote patient satisfaction and quality of

    In silico, defined in analogy to in vitro and in vivo as those studies that are performed on a computer, is an essential step in problem-solving and product development in classical engineering fields. The use of in silico models is now slowly easing its way into medicine. In silico models are already used in orthopaedics for the planning of complicated surgeries, personalised implant design and the analysis of gait measurements. However, these in silico models often lack the simulation of the response of the biological system over time. In silico models focusing on the response of the biological systems are in full development. This review starts with an introduction into in silico models of orthopaedic processes. Special attention is paid to the classification of models according to their spatiotemporal scale (gene/protein to population) and the information they were built on (data vs hypotheses). Subsequently, the review focuses on the in silico models used in regenerative orthopaedics research. Contributions of in silico models to an enhanced understanding and optimisation of four key elements-cells, carriers, culture and clinics-are illustrated. Finally, a number of challenges are identified, related to the computational aspects but also to the integration of in silico tools into clinical practice.

    The utilization of orthopaedic services (office visits and surgery) to treat hand and wrist conditions is not well known. In this study, we report the utilization rates for patients referred for orthopaedic treatment of hand and wrist conditions in a large population of individuals enrolled in a capitated insurance plan. The study population consisted of individuals enrolled, between January 1998 and December 2001, in a capitated insurance plan that had an annual average membership of 135,188 during that period. This plan was serviced by an independent physician association of sixty-two orthopaedic surgeons who were responsible for all orthopaedic care. Data were collected prospectively in a centralized database as patients with various hand or wrist conditions were referred for orthopaedic services. Odds ratios were used to compare gender-specific and age-specific utilization rates. Overall utilization rates were 18.06 office visits and 6.47 surgical procedures per 1000 members per year. The most frequent hand or wrist conditions were fractures, carpal tunnel syndrome, tendinitis or tenosynovitis, and ganglion or synovial cysts. These four diagnoses accounted for 70% of all office visits and 71% of all surgical cases. Across all age groups, males had a significantly higher rate of utilization of office visits (p hand or wrist condition, and nearly half will require surgery.

    2015-11-01

    Full Text Available Currently, there are constraints on coordination between the primary and secondary levels of care, and we lack a regulatory document for surgical activity in major ambulatory and short-stay surgery, which affects the quality of this modality of care. Such reasons led to the design of the “Organization and Procedures Guide for Performing Major Ambulatory and Short-stay Surgery in Coordination with the Primary Health Care Team". The guide was assessed by 90 experts with experience in the primary and secondary levels of care, who endorsed the quality and relevance of the proposal. It contains recommendations to help primary and secondary care professionals involved in surgical care to select the most appropriate approach to conditions treated by means of ambulatory or short-stay surgery. The recommendations are based on the latest available scientific evidence supporting the use of ambulatory surgery, short-stay surgery and home hospitalization.

    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.

    Summary Objective Epilepsy surgery is the most effective treatment for select patients with drug-resistant epilepsy. In this article, we aim to provide an accurate understanding of the current epidemiologic characteristics of this intervention, as this knowledge is critical for guiding educational, academic, and resource priorities. Methods We profile the practice of epilepsy surgery between 1991 and 2011 in nine major epilepsy surgery centers in the United States, Germany, and Australia. Clinical, imaging, surgical, and histopathologic data were derived from the surgical databases at various centers. Results Although five of the centers performed their highest number of surgeries for mesial temporal sclerosis (MTS) in 1991, and three had their highest number of MTS surgeries in 2001, only one center achieved its peak number of MTS surgeries in 2011. The most productive year for MTS surgeries varied then by center; overall, the nine centers surveyed performed 48% (95% confidence interval [CI] −27.3% to −67.4%) fewer such surgeries in 2011 compared to either 1991 or 2001, whichever was higher. There was a parallel increase in the performance of surgery for nonlesional epilepsy. Further analysis of 5/9 centers showed a yearly increase of 0.6 ± 0.07% in the performance of invasive electroencephalography (EEG) without subsequent resections. Overall, although MTS was the main surgical substrate in 1991 and 2001 (proportion of total surgeries in study centers ranging from 33.3% to 70.2%); it occupied only 33.6% of all resections in 2011 in the context of an overall stable total surgical volume. Significance These findings highlight the major aspects of the evolution of epilepsy surgery across the past two decades in a sample of well-established epilepsy surgery centers, and the critical current challenges of this treatment option in addressing complex epilepsy cases requiring detailed evaluations. Possible causes and implications of these findings are discussed

    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.

    Full Text Available Even though free tissue transfers are a routine in many centres, pedicle flaps still have a huge roll to play in our country. There are many centres in the country where pedicle flaps are in use because of logistic problems. Deltopectoral and pectoralis muscle flaps are usually preferred for composite cheek defects. When both these flaps are used in combination it is a two-staged procedure. We describe a single-stage procedure to reconstruct a composite cheek defect with pectoralis major myocutaneous flap for lining and single-stage deltopectoral flap for cover. In the available literature search, single-stage DP and PMMC have not been described for management of composite cheek defect.

    A combined subjective and objective wireless monitoring program of patient-centered outcomes can be carried out in patients before and after major abdominal cancer surgery. To conduct a proof-of-concept pilot study of a wireless, patient-centered outcomes monitoring program before and after major abdominal cancer surgery. In this proof-of-concept pilot study, patients wore wristband pedometers and completed online patient-reported outcome surveys (symptoms and quality of life) 3 to 7 days before surgery, during hospitalization, and up to 2 weeks after discharge. Reminders via email were generated for all moderate to severe scores for symptoms and quality of life. Surgery-related data were collected via electronic medical records, and complications were calculated using the Clavien-Dindo classification. The study was carried out in the inpatient and outpatient surgical oncology unit of one National Cancer Institute-designated comprehensive cancer center. Eligible patients were scheduled to undergo curative resection for hepatobiliary and gastrointestinal cancers, were English speaking, and were 18 years or older. Twenty participants were enrolled over 4 months. The study dates were April 1, 2015, to July 31, 2016. Outcomes included adherence to wearing the pedometer, adherence to completing the surveys (MD Anderson Symptom Inventory and EuroQol 5-dimensional descriptive system), and satisfaction with the monitoring program. This study included a final sample of 20 patients (median age, 55.5 years [range, 22-74 years]; 15 [75%] female) with evaluable data. Pedometer adherence (88% [17 of 20] before surgery vs 83% [16 of 20] after discharge) was higher than survey adherence (65% to 75% [13 of 20 and 15 of 20] completed). The median number of daily steps at day 7 was 1689 (19% of daily steps at baseline), which correlated with the Comprehensive Complication Index, for which the median was 15 of 100 (r = -0.64, P < .05). Postdischarge overall symptom severity (2

    Rivaroxaban is a novel oral anticoagulant indicated for prophylaxis against deep vein thrombosis and pulmonary embolism in patients undergoing total hip replacement (THR) or total knee replacement (TKR) surgery. To evaluate major bleeding (MB) in THR/TKR patients receiving post-operative rivaroxaban. Electronic medical records of nearly 10 million US Department of Defense (DoD) beneficiaries were queried from 1 January 2013 through 30 June 2015. Using the validated Cunningham case-finding algorithm, post-surgical MB events in rivaroxaban users were identified and analyzed. The incidence of MB was determined, and descriptive statistics were used to compare patient characteristics and other covariates in those with and without MB. Two additional methods were used to explore and identify bleeding cases that were not considered MB events per the study case-finding algorithm. A total of 12,429 patients received THR and/or TKR surgery, and were post-operatively prescribed rivaroxaban. Nine patients had MB, yielding an incidence proportion of 0.07% (95% CI 0.02-0.13). The alternative case-finding methods found bleeding incidences of 0.46% and 0.21%, though it is not clear whether these are clinical MB cases, since the alternative methods were not validated. The incidence of MB in this retrospective analysis is lower than that observed in the clinical trials of rivaroxaban. Whether this is due to lower real-world MB rates or challenges with case-finding algorithms is unclear.

    BACKGROUND: Patients undergoing major vascular surgery (MVS) require extensive anaesthetic assessment. This can require extended pre-operative stays. AIMS: We investigated whether a newly established anaesthetic pre-operative assessment clinic (PAC) would reduce the pre-operative inpatient stay, avoid unnecessary investigations and facilitate day before surgery (DBS) admissions for patients undergoing MVS. PATIENT AND METHODS: One year following and preceding the establishment of the PAC the records of patients undergoing open or endovascular aortic aneurysm repair, carotid endarterectomy and infra-inguinal bypass were reviewed to measure pre-operative length of stay (LoS). RESULTS: Pre-operative LoS was significantly reduced in the study period (1.85 vs. 4.2 days, respectively, P < 0.0001). Only 12 out of 61 patients in 2007 were admitted on the DBS and this increased to 33 out of 63 patients (P = 0.0002). No procedure was cancelled for medical reasons. CONCLUSION: The PAC has facilitated accurate outpatient anaesthetic assessment for patients requiring MVS. The pre-operative in-patient stay has been significantly reduced.

    We conducted a randomized, prospective study to assess the effect of i.v. insulin on blood glucose control, development of ketone bodies and hormonal changes in 60 well-controlled, non-insulin-dependent diabetics (NIDDM) undergoing major surgery. In group A, patients were given only 0.9% saline; in group B, patients were given insulin as a continuous i.v. infusion (1.25 u. h-1); in group C, patients were given insulin 10 u. i.v. boluses every 2 h. Patients in all three groups were given insulin 5 u. when their intraoperative blood glucose concentration increased to greater than 11.1 mmol litre-1. Blood glucose concentrations were measured every 15 min, from just before induction of anaesthesia to 2 h after surgery. Plasma lactate, pyruvate, ketone body, C-peptide and counter-regulatory hormone concentrations were also measured. Blood glucose concentrations in the three groups did not differ significantly. There was a mild-to-moderate increase in plasma ketone body concentrations in group A, but without any deleterious consequences. Plasma C-peptide concentrations decreased significantly in groups B and C, especially in patients given bolus injections of insulin. Plasma growth hormone concentrations also increased significantly in group B and C patients. This study indicated that the "no insulin--no glucose" regimen was a simple, effective way to control blood glucose in well-controlled NIDDM patients, provided blood glucose was measured frequently and insulin used appropriately.

  2. Bioactive Coatings for Orthopaedic Implants—Recent Trends in Development of Implant Coatings

    Full Text Available Joint replacement is a major orthopaedic procedure used to treat joint osteoarthritis. Aseptic loosening and infection are the two most significant causes of prosthetic implant failure. The ideal implant should be able to promote osteointegration, deter bacterial adhesion and minimize prosthetic infection. Recent developments in material science and cell biology have seen the development of new orthopaedic implant coatings to address these issues. Coatings consisting of bioceramics, extracellular matrix proteins, biological peptides or growth factors impart bioactivity and biocompatibility to the metallic surface of conventional orthopaedic prosthesis that promote bone ingrowth and differentiation of stem cells into osteoblasts leading to enhanced osteointegration of the implant. Furthermore, coatings such as silver, nitric oxide, antibiotics, antiseptics and antimicrobial peptides with anti-microbial properties have also been developed, which show promise in reducing bacterial adhesion and prosthetic infections. This review summarizes some of the recent developments in coatings for orthopaedic implants.

    Cell-surface interactions play a crucial role for biomaterial application in orthopaedics. It is evident that not only the chemical composition of solid substances influence cellular adherence, migration, proliferation and differentiation but also the surface topography of a biomaterial. The progressive application of nanostructured surfaces in medicine has gained increasing interest to improve the cytocompatibility and osteointegration of orthopaedic implants. Therefore, the understanding of cell-surface interactions is of major interest for these substances. In this review, we elucidate the principle mechanisms of nano- and microscale cell-surface interactions in vitro for different cell types onto typical orthopaedic biomaterials such as titanium (Ti), cobalt-chrome-molybdenum (CoCrMo) alloys, stainless steel (SS), as well as synthetic polymers (UHMWPE, XLPE, PEEK, PLLA). In addition, effects of nano- and microscaled particles and their significance in orthopaedics were reviewed. The significance for the cytocompatibility of nanobiomaterials is discussed critically.

    Twenty patients with impaired left ventricular function during exercise, who underwent major vascular surgery for arteriosclerotic disease, were randomly digitalized in the immediate postoperative period. All patients had a smooth postoperative course. Haemodynamic measurements showed improved left ventricular function in those who received digitalis, since 60 min after full digitalization the digitalized patients had a highly significant decrease in pulmonary capillary wedge pressure (PCWP) with unchanged stroke volume index (SVI) and left ventricular stroke work index (LVSWI). The same improvement in cardiac function was present the next morning. The present study provides haemodynamic data in support of clinical studies showing a beneficial effect of prophylactic digitalization in surgical patients with clinical signs of arteriosclerotic heart disease, though not in overt failure.

    Preoperative risk stratification is a critical element in assessing the risks and benefits of surgery. Prior work has demonstrated that intra-abdominal general surgery patients can be classified based on their comorbidities and risk factors using latent class analysis (LCA), a model-based clustering technique designed to find groups of patients that are similar with respect to characteristics entered into the model. Moreover, the latent risk classes were predictive of 30-day mortality. We evaluated the use of latent risk classes to predict the risk of major postoperative complications. An observational, retrospective cohort of patients undergoing intra-abdominal general surgery in the 2005 to 2010 American College of Surgeons National Surgical Quality Improvement Program was obtained. Known preoperative comorbidity and risk factor data were entered into LCA models to identify the latent risk classes. Complications were defined as: acute kidney injury, acute respiratory failure, cardiac arrest, deep vein thrombosis, myocardial infarction, organ space infection, pneumonia, postoperative bleeding, pulmonary embolism, sepsis/septic shock, stroke, unplanned reintubation, and/or wound dehiscence. Relative risk regression determined the associations between the latent classes and the 30-day complication risks, with adjustments for the surgical procedure. The area under the curve (AUC) of the receiver operator characteristic curve assessed model performance. LCA fit a 9-class model on 466,177 observations. The composite complication risk was 18.4% but varied from 7.7% in the lowest risk class to 56.7% in the highest risk class. After adjusting for procedure, the latent risk classes were significantly associated with complications, with risk ratios (95% confidence intervals) (compared to the class with the average risk) varying from 0.56 (0.54-0.58) in the lowest risk class to 2.15 (2.11-2.20) in the highest risk class, a 4-fold difference. In models incorporating surgical

    Full Text Available Blood transfusion is associated with well-known risks. We investigated the difference between a restrictive versus a liberal transfusion strategy on the immune response, as expressed by the production of inflammatory mediators, in patients subjected to major abdominal surgery procedures. Fifty-eight patients undergoing major abdominal surgery were randomized preoperatively to either a restrictive transfusion protocol or a liberal transfusion protocol (with transfusion if hemoglobin dropped below 7.7 g dL−1 or 9.9 g dL−1, respectively. In a subgroup of 20 patients randomly selected from the original allocation groups, blood was sampled for measurement of IL-6, IL-10, and TNFα. Postoperative levels of IL-10 were higher in the liberal transfusion group on the first postoperative day (49.82±29.07 vs. 15.83±13.22 pg mL−1, P<0.05. Peak postoperative IL-10 levels correlated with the units of blood transfused as well as the mean duration of storage and the storage time of the oldest unit transfused (r2=0.38, P=0.032, r2=0.52, P=0.007, and r2=0.68, P<0.001, respectively. IL-10 levels were elevated in patients with a more liberal red blood cell transfusion strategy. The strength of the association between anti-inflammatory IL-10 and transfusion variables indicates that IL-10 may be an important factor in transfusion-associated immunomodulation. This trial is registered under ClinicalTrials.gov Identifier: NCT02020525.

    The opinions of the pediatric orthopaedic workforce are shaped by market forces, regulatory processes, and local experience. The purpose of this report is to summarize the findings of the recent Workforce Survey of the American Academy of Pediatrics (AAP) Section on Orthopaedics (SOOr). This submission has been reviewed and approved by the Board of Directors of the Pediatric Orthopaedic Society of North America (POSNA). In 2014, the AAP generated a survey to assess perceptions of pediatric orthopaedic surgeons about current issues that affect practice. The survey was sent to 856 POSNA and 141 AAP-SOOr members. Responses were topically organized to report current workforce composition, practice patterns, and perceptions about electronic medical records (EMRs). Responses were collected from August to December, 2014, from 496 (50%) survey recipients including 83 of 141 (59%) AAP-SOOr members and 413 of 856 (48%) POSNA members. Analyses were restricted to the 397 respondents who reported that they are currently practicing pediatric orthopaedics. Nearly all of these (390/391, 100%) indicated that they provide direct patient care and work an average of 60 hours per week. Many (105/378, 28%) indicated that they would soon limit their practice or retire. A majority (299/394, 76%) indicated that they face competition in their geographic area, predominantly due to pediatric orthopaedic subspecialists (269/299, 90%). Major business changes had recently occurred or were anticipated by 21% of participants. Respondents reported that use of EMR makes them less efficient (252/397, 63%) and interferes with the patient-physician relationship (172/397, 43%). This workforce survey suggests that pediatric orthopaedic surgeons are concerned with challenges of competition despite concurrent increasing volume and complexity of referrals. External processes such as EMR changes are perceived to negatively impact practice efficiency and satisfaction.

    Myotonic Dystrophy Type 1 (DM1) is the most common form of hereditary myopathy presenting in adults. This autosomal-dominant systemic disorder is caused by a CTG repeat, demonstrating various symptoms. A mild, classic and congenital form can be distinguished. Often the quality of life is reduced by orthopaedic problems, such as muscle weakness, contractures, foot or spinal deformities, which limit patients' mobility.The aim of our study was to gather information about the orthopaedic impairments in patients with DM1 in order to improve the medical care of patients, affected by this rare disease. A retrospective clinical study was carried out including 21 patients (11 male and 10 female), all diagnosed with DM1 by genetic testing. All patients were seen during our special consultations for neuromuscular diseases, during which patients were interviewed and examined. We also reviewed surgery reports of our hospitalized patients. We observed several orthopaedic impairments: spinal deformities (scoliosis, hyperkyphosis, rigid spine), contractures (of the upper extremities and the lower extremities), foot deformities (equinus deformity, club foot, pes cavus, pes planovalgus, pes cavovarus, claw toes) and fractures.Five patients were affected by pulmonary diseases (obstructive airway diseases, restrictive lung dysfunctions). Twelve patients were affected by cardiac disorders (congenital heart defects, valvular heart defects, conduction disturbances, pulmonary hypertension, cardiomyopathy).Our patients received conservative therapy (physiotherapy, logopaedic therapy, ergotherapy) and we prescribed orthopaedic technical devices (orthopaedic custom-made shoes, insoles, lower and upper leg orthoses, wheelchair, Rehab Buggy). We performed surgery for spinal and foot deformities: the scoliosis of one patient was stabilized and seven patients underwent surgery for correction of foot deformities. An orthopaedic involvement in DM1 patients should not be underestimated. The most

    2015-01-01

    In the specialty of orthopaedics, methicillin-resistant Staphylococcus aureus (MRSA) is a major contributor to infections of the soft tissues, surgical sites, and joints, in addition to increasing disability, mortality, and healthcare costs. Inappropriate prescribing and misuse of antibiotics have led to bacterial resistance and the rapid emergence of MRSA. It is imperative for healthcare providers and facilities to improve quality, promote safety, and decrease costs related to MRSA infections. The healthcare profession and society as a whole play an important role in minimizing the transmission of pathogens, reducing the incidence of MRSA infections, and decreasing the development of future antibiotic resistant pathogens. This article discusses the epidemiology of MRSA and describes evidence-based guidelines pertaining to the prevention, minimization, and treatment of MRSA-related infections. Specific application to orthopaedics are discussed in the context of patient risk factors, perioperative and postoperative prophylaxis, and current trends regarding education and reporting strategies.

    2012-01-01

    Many primary care physicians believe that there are too few pediatric orthopaedic specialists available to meet their patients' needs. However, a recent survey by the Practice Management Committee of the Pediatric Orthopaedic Society of North America found that new referrals were often for cases that could have been managed by primary care practitioners. We wished to determine how many new referral cases seen by pediatric orthopaedic surgeons are in fact conditions that can be readily managed by a primary care physician should he/she chose to do so. We prospectively studied all new referrals to our hospital-based orthopaedic clinic during August 2010. Each new referral was evaluated for whether it met the American Board of Pediatrics criteria for being a condition that could be managed by a primary care pediatrician. Each referral was also evaluated for whether it met the American Academy of Pediatrics Surgery Advisory Panel guidelines recommending referral to an orthopaedic specialist, regardless of whether it is for general orthopaedics or pediatric orthopaedics. On the basis of these criteria, we classified conditions as either a condition manageable by primary care physicians or a condition that should be referred to an orthopaedic surgeon or a pediatric orthopaedic surgeon. We used these guidelines not to identify diagnosis that primary care physicians should treat but, rather, to compare the guideline-delineated referrals with the actual referrals our specialty pediatric orthopaedic clinic received over a period of 1 month. A total of 529 new patient referrals were seen during August 2010. A total of 246 (47%) were considered primary care conditions and 283 (53%) orthopaedic specialty conditions. The most common primary care condition was a nondisplaced phalanx fracture (25/246, 10.1%) and the most common specialty condition was a displaced single-bone upper extremity fracture needing reduction (36/283, 13%). Only 77 (14.6%) of the total cases met the strict

    Objective To compare and evaluate the effect and safety of dexmedetomidine(DEX) and midazolam sedation in lower limbs orthopaedic surgery. Methods Fifty-two patients undergoing lower limbs surgery were randomly assigned to group D (n=27,DEX, 0.5 μg·kg-1·h-1, loading dose 0.5 μg/kg) and group M(n=25, midazolam, 50 μg·kg-1·h-1, loading dose 30 μg/kg). An infusion was administered after mounting a bispectral index (BIS) monitor under combined spinal-epidural anesthesia. The target BIS level was≤85. An additional bolus dose of the study drug or cessation of the infusion was adjusted according to the BIS level, and the change should be recorded. Respiratory rates (RR), heart rate (HR), pulse oxygen saturation (SpO2), mean arterial blood pressure (MAP) were continually monitored. Sedation should be evaluated according to the Ramsay sedation scale(RSS) before the drug withdrawal. Results HR was lower in group D (72±7) bpm than that in group M (83±8) bpm (P0.05).两组的停药前RSS评分差异无统计学意义(P>0.05).D组有6例、M组有7例需要进行剂量调整.另外,M组有5例因舌后坠致SpO2下降需托下颌处理,D组无类似情况.结论 DEX用于骨科下肢手术镇静可引起HR减慢但对血压无明显影响;在相同的镇静程度下,DEX比咪达唑仑更有利丁维持呼吸道通畅,可能更适用于该类手术的镇静.

    Peripheral arterial disease (PAD) has the risk equivalent of coronary heart disease. The biochemical parameters associated with functionally significant coronary artery stenosis were investigated in asymptomatic patients with PAD who were scheduled for major vascular intervention. A total of 50 PAD patients asymptomatic for coronary heart disease were examined using coronary computed tomography angiography (CTA). A stress myocardial CT perfusion (CTP) test was performed in patients who exhibited coronary stenosis >40%. In patients with stress-induced perfusion defects, the severity of stenosis was assessed using invasive coronary angiography including fractional flow reserve assessment. The CT findings were correlated with both classical and more recently developed parameters of atherosclerosis. According to the combined CT examination (CTA and stress CT perfusion), 36% of patients exhibited significant coronary stenosis. Stress-induced hypoperfusion was observed in 95.7% of severe stenotic lesions. After adjustment for confounders, the level of high-sensitivity troponin I was associated with severe coronary stenosis (OR 1.260 [95% CI 1.054 to 1.505]). Other biochemical parameters did not correlate with coronary stenosis. The annual mortality rate was 4%. The results of the present study confirm a significant diagnostic contribution of a complex cardiac CT examination in patients scheduled for major vascular surgery. A high prevalence of asymptomatic coronary heart disease was observed in this particular patient group. High-sensitivity measurements of troponin I correlated with the extent of the coronary stenosis.

The main objective of our study was to evaluate the predictive value of heart-rate variability (HRV concerning development of postoperative complications in patients undergoing MAS. The secondary objectives were to identify the relationship of HRV and use of vasoactive drugs during anesthesia, intensive care unit length of stay (ICU-LOS, and hospital length of stay (H-LOS. Patients and methods: Sixty-five patients scheduled for elective MAS were enrolled in a prospective, single-center, observational study. HRV was measured by spectral analysis (SA preoperatively during orthostatic load. Patients were divided according to cardiac autonomic reactivity (CAR; n=23 and non-cardiac autonomic reactivity (NCAR; n=30. Results: The final analysis included 53 patients. No significant difference was observed between the two groups regarding type of surgery, use of minimally invasive techniques or epidural catheter, duration of surgery and anesthesia, or the amount of fluid administered intraoperatively. The NCAR group had significantly greater intraoperative blood loss than the CAR group (541.7±541.9 mL vs 269.6±174.3 mL, p<0.05. In the NCAR group, vasoactive drugs were used during anesthesia more frequently (n=21 vs n=4; p<0.001, and more patients had at least one postoperative complication compared to the CAR group (n=19 vs n=4; p<0.01.

    As residency training programmes around the globe move towards competency-based medical education (CBME), there is a need to review current teaching and assessment practices as they relate to education in orthopaedic trauma. Assessment is the cornerstone of CBME, as it not only helps to determine when a trainee is fit to practice independently, but it also provides feedback on performance and guides the development of competence. Although a standardised core knowledge base for trauma care has been developed by the leading national accreditation bodies and international agencies that teach and perform research in orthopaedic trauma, educators have not yet established optimal methods for assessing trainees' performance in managing orthopaedic trauma patients. This review describes the existing knowledge from the literature on assessment in orthopaedic trauma and highlights initiatives that have recently been undertaken towards CBME in the United Kingdom, Canada and the United States. In order to support a CBME approach, programmes need to improve the frequency and quality of assessments and improve on current formative and summative feedback techniques in order to enhance resident education in orthopaedic trauma.

    Despite efforts to enhance the patient experience, many health care providers continue to struggle to improve patient satisfaction as the identification of tangible quality improvement areas remains difficult. This dilemma is particularly relevant in pediatric settings, where patient satisfaction measures have not been as thoroughly studied in subspecialties such as orthopaedics. We investigate this issue to identify the major drivers of patient satisfaction in pediatric orthopaedics, which has significant financial and professional implications for both hospital administrators and health care providers. Although recent patient experience studies emphasize on improving access to care and nurturing hospitality by facilities upgrades or staff development, we hypothesized that the patient-physician relationship remains the most important factor in patients' assessment of their experiences. Patient satisfaction surveys were collected from outpatient visits to pediatric orthopaedic practices at 5 locations in 3 states. Data were aggregated as monthly percentages of responses on a 5-point Likert scale. Month over month Pearson product-moment correlation coefficients were generated between top responses for "Likelihood of Your Recommending Our Practice to Others" (LTR) and other variables. In total, 6195 families completed satisfaction surveys. The variables most predictive of likelihood to recommend the practice were "Staff Worked Together" (r=0.82), "Friendliness/Courtesy of Care Provider" (r=0.80), "Cheerfulness of Practice" (r=0.80), "Likelihood of Recommending Care Provider" (r=0.80), and "Care Provider's Information about Medications" (r=0.78). Measurements of the patient-physician relationship, along with overall cheerfulness and staff collaboration, have the strongest relationships to LTR. These results suggest that patient satisfaction is influenced by more than just the patient-physician relationship, and may have significance in aiding pediatric orthopaedic

    The use of handbooks is becoming more widespread in hospital medicine. A review of their use in British orthopaedics received 78 replies (29 per cent) representing 94 (30 per cent) of the orthopaedic units in the United Kingdom. Seventy-five per cent used a handbook, were preparing one or would like to have one. Recommendations are given for the content and format of a handbook, a specimen of which has been prepared.

    The treatment and rehabilitation procedures of anterior cruciate ligament (ACL) injuries in elite soccer players are controversial. Points of debate include surgical timing, technique, graft choice, rehabilitation, and return-to-sport criteria and timing. To identify practice preferences among current Major League Soccer (MLS) team orthopaedic surgeons for ACL injuries. Cross-sectional study; Level of evidence, 4. The survey was administered at the MLS team physician annual meeting in January 2013. At least 1 orthopaedic surgeon representative from each of the 19 clubs (16 from the United States, 3 from Canada) was in attendance. Teams with more than 1 affiliated orthopaedic surgeon were given an additional survey to be completed either at the meeting or returned via e-mail. Descriptive statistics, Wilcoxon Mann-Whitney (return-to-play parameters, running, and ball drills), and Fisher exact tests (graft selection, bracing, continuous passive motion) were applied to the various data sets from the survey responses. A 100% survey participation rate was achieved (22 team orthopaedic surgeons representing 19 MLS teams). A single-incision, arthroscopically assisted, single-bundle reconstruction was the most common technique (91%). Surgeons were split regarding femoral tunnel drilling (50% transtibial, 46% accessory medial). Autograft bone-patellar tendon-bone (BPTB) was the most common preferred graft choice (68%). The biggest concerns about BPTB autograft and hamstring autograft were anterior knee pain (76%) and hamstring weakness (46%), respectively. Most surgeons did not recommend postoperative continuous passive motion (64%) or functional bracing (68%). Most surgeons permitted return to sport without restrictions at 6 to 8 months following surgery (82%). Surgeons who routinely used functional bracing after ACL surgery more frequently used hamstring autograft than those who used BPTB autograft (P = .04).

    Accurate body core temperature measurement is essential in perioperative areas to quickly recognize and address abnormal temperatures. The purposes of this prospective, descriptive study were to accurately identify unplanned perioperative hypothermia (UPH) in 64 elective major surgery patients; to describe factors that increased the risk of UPH; to describe active/passive warming measures; to describe thermal comfort in patients with and without UPH; and to compare oral, temporal artery, and bladder temperatures. Based on bladder temperatures, 52% of the patients had UPH in the operating room (OR) and 42% on postanesthesia care unit (PACU) admission. The temporal artery thermometer did not detect any hypothermia. Descriptive data and Bland-Altman plots showed lack of agreement between the temporal artery thermometer readings and those of the oral and bladder thermometers. The patient's thermal comfort report did not accurately reflect hypothermia. Factors found to increase the risk of UPH included older age, BMI lower than 30, and OR ambient temperature lower than 68°F. All but one patient had active warming in the OR; active warming was infrequently used in the PACU. Based on our findings and findings in previous studies, we do not recommend using the temporal artery thermometer in perioperative areas. To prevent UPH, we recommend aggressive use of convective and conductive warming measures in perioperative areas and increasing OR ambient temperatures.

    2017-05-01

    Full Text Available Background: Venous thromboembolism (VTE is a potentially fatal complication of orthopedic surgery, and until recently, few antithrombotic compounds were available for postoperative thromboprophylaxis. The introduction of the non–vitamin K antagonists oral anticoagulants (NOAC, including apixaban, has extended the therapeutic armamentarium in this field. Therefore, estimation of NOAC net clinical benefit in comparison with the established treatment is needed to inform clinical decision making. Objectives: Systematic review to assess the efficacy and safety of apixaban 2.5 mg twice a day versus low-molecular-weight heparins (LMWH for thromboprophylaxis in patients undergoing knee or hip replacement. Data sources: MEDLINE, Embase, and CENTRAL were searched from inception to September 2016, other systematic reviews, reference lists, and experts were consulted. Study eligibility criteria, participants, and intervention: All major orthopedic surgery randomized controlled trials comparing apixaban 2.5 mg twice daily with LMWH, reporting thrombotic and bleeding events. Data extraction: Two independent reviewers, using a predetermined form. Study appraisal and synthesis methods: The Cochrane tool to assess risk bias was used by two independent authors. RevMan software was used to estimate pooled risk ratio (RR and 95% confidence intervals (95% CI using random-effects meta-analysis. Trial sequential analysis (TSA was performed in statistical significant results to evaluate whether cumulative sample size was powered for the obtained effect. Overall confidence in cumulative evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE Working Group methodology. Results: Four studies comparing apixaban 2.5 mg twice daily with LMWH were included, with a total of 11.828 patients (55% undergoing knee and 45% hip replacement. The overall risk of bias across studies was low. In comparison with LMWH (all regimens

    During the past century, man-made materials and devices have been developed to the point at which they have been used successfully to replace and/or restore function to diseased or damaged tissues. In the field of orthopaedics, the use of metal implants has significantly improved the quality of life for countless individuals. Critical factors for implant success include proper design, material selection, and biocompatibility. While early research focused on the understanding biomechanical properties of the metal device, recent work has turned toward improving the biological properties of these devices. This has lead to the introduction of calcium phosphate (CaP) bioceramics as a bioactive interface between the bulk metal impart and the surrounding tissue. The first calcium phosphate coatings where produced via vapor phase routes but more recently, there has been the emergence of solution based and biomimetic methods. While each approach has its own intrinsic materials and biological properties, in general CaP coatings have the promise to improve implant biocompatibility and ultimately implant longevity.

    Acute Achilles tendon ruptures are common among highly active people. Recently published studies have provided increasing evidence to support non-surgical treatment. This study aimed to assess the incidence trends of surgically treated, acute Achilles tendon ruptures. Our hypothesis, based on the recent literature showing no difference in functional results between surgical and non-surgical treatment, was that the incidence of surgery would be declining. We conducted a nationwide hospital register-based study. All patients 18 years of age or older with a diagnosis of acute Achilles tendon injury, and treated with Achilles tendon repair from 1987 to 2011 in Finland were included in the study. During the 25-year study period in Finland, a total of 15,252 patients received surgical treatment for an acute Achilles tendon rupture. The incidence of surgical treatment of acute Achilles tendon rupture in men was 11.1/100,000 person-years in 1987 and 20.5/100,000 person-years in 2011. The corresponding figures in women were 2.5/100,000 person-years in 1987 and 4.2/100,000 person-years in 2011. The highest rates occurred in 2008 in men and 2007 in women, and since then the decrease has been 42% in men and 55% in women. During the past few years, the rate of surgically treated acute Achilles tendon ruptures has declined remarkably. The findings of the present study indicate that orthopaedic surgeons have chosen more often non-surgical treatment option for acute Achilles ruptures. This can be considered as an example, how high-quality scientific evidence can lead to a rapid change in clinical practice. Published by the BMJ Publishing Group Limited.

    The impact of preoperative stable angina pectoris on postoperative cardiovascular outcomes in patients with previous myocardial infarction (MI) who underwent major noncardiac surgery is not well studied. We studied patients with previous MI who underwent elective major noncardiac surgeries within the American College of Surgeons-National Surgical Quality Improvement Program (2005 to 2011). Primary outcome was occurrence of an adverse cardiac event (MI and/or cardiac arrest). Multivariable logistic regression models evaluated the impact of stable angina on outcomes. Of 1,568 patients (median age 70 years; 35% women) with previous MI who underwent major noncardiac surgery, 5.5% had postoperative MI and/or cardiac arrest. Patients with history of preoperative angina had significantly greater incidence of primary outcome compared to those without anginal symptoms (8.4% vs 5%, p = 0.035). In secondary outcomes, reintervention rates (22.5% vs 11%, p angina. In multivariable analyses, preoperative angina was a significant predictor for postoperative MI (odds ratio 2.49 [1.20 to 5.58]) and reintervention (odds ratio 2.40 [1.44 to 3.82]). In conclusion, our study indicates that preoperative angina is an independent predictor for adverse outcomes in patients with previous MI who underwent major noncardiac surgery, and cautions against overreliance on predictive tools, for example, the Revised Cardiac Risk Index, in these patients, which does not treat stable angina and previous MI as independent risk factors during risk prognostication.

    Healthcare reimbursement models are changing. Fee-for-service may be replaced by pay-for-performance or capitated care. The purpose of this study was to examine the potential changes in orthopaedic trauma surgery patient management based on potential shifts in policy surrounding readmission and reimbursement. An e-mail survey consisting of 3 case-based scenarios was delivered to 375 orthopaedic surgeons. Five options for management of each case were provided. Each of the 3 cases was presented in 3 different healthcare settings: scenario A, our current healthcare setting; scenario B, in which 90-day reoperation or readmission would not be reimbursed; and scenario C, in which a capitated healthcare structure paid a fixed amount per patient. The response rate was 40.3% with 151 surgeons completing the survey. A 71.1% of the respondents were in private practice settings, whereas 28.3% were in academic centers. In each case, there was significant increase in the respondents' choice to transfer patients to tertiary care centers under both the capitated and penalization systems as compared with the current fee-for-service model. This survey is the first of its kind to demonstrate through case-based scenarios that a healthcare system with readmission penalties and capitated reimbursement models may lead to a significant increase in transfer of complex orthopaedic trauma patients to tertiary care centers. Physicians should be encouraged to continue evidence-based medicine instead of making decisions due to finances, and other avenues of healthcare savings should be explored to decrease patient transfer rates with healthcare changes.

    Full Text Available Abstract Background Surgical site infection (SSI continues to be a major source of morbidity and mortality in developing countries despite recent advances in aseptic techniques. There is no baseline information regarding SSI in our setting therefore it was necessary to conduct this study to establish the prevalence, pattern and predictors of surgical site infection at Bugando Medical Centre Mwanza (BMC, Tanzania. Methods This was a cross-sectional prospective study involving all patients who underwent major surgery in surgical wards between July 2009 and March 2010. After informed written consent for the study and HIV testing, all patients who met inclusion criteria were consecutively enrolled into the study. Pre-operative, intra-operative and post operative data were collected using standardized data collection form. Wound specimens were collected and processed as per standard operative procedures; and susceptibility testing was done using disc diffusion technique. Data were analyzed using SPSS software version 15 and STATA. Results Surgical site infection (SSI was detected in 65 (26.0% patients, of whom 56 (86.2% and 9 (13.8% had superficial and deep SSI respectively. Among 65 patients with clinical SSI, 56(86.2% had positive aerobic culture. Staphylococcus aureus was the predominant organism 16/56 (28.6%; of which 3/16 (18.8% were MRSA. This was followed by Escherichia coli 14/56 (25% and Klebsiella pneumoniae 10/56 (17.9%. Among the Escherichia coli and Klebsiella pneumoniae isolates 9(64.3% and 8(80% were ESBL producers respectively. A total of 37/250 (14.8% patients were HIV positive with a mean CD4 count of 296 cells/ml.

    Full Text Available Postoperative complications frequently follow major abdominal surgery and are associated with increased morbidity and mortality. Early diagnosis and treatment of complications is associated with improved patient outcome. In this study we assessed the value of a step-up diagnosis plan by C-reactive protein and CT-scan (computed tomography-scan imaging for detection of postoperative complications following major abdominal surgery. An observational cohort study was conducted of 399 consecutive patients undergoing major abdominal surgery between January 2009 and January 2011. Indication for operation, type of surgery, postoperative morbidity, complications according to the Clavien-Dindo classification and mortality were recorded. Clinical parameters were recorded until 14 days postoperatively or until discharge. Regular C-reactive protein (CPR measurements in peripheral blood and on indication -enhanced CT-scans were performed. Eighty-three out of 399 (20.6 % patients developed a major complication in the postoperative course after a median of seven days (IQR 4-9 days. One hundred and thirty two patients received additional examination consisting of enhanced CT-scan imaging, and treatment by surgical reintervention or intensive care observation. CRP levels were significantly higher in patients with postoperative complications. On the second postoperative day CRP levels were on average 197.4 mg/L in the uncomplicated group, 220.9 mg/L in patients with a minor complication and 280.1 mg/L in patients with major complications (p < 0,001. CT-scan imaging showed a sensitivity of 91.7 % and specificity of 100 % in diagnosis of major complications. Based on clinical deterioration and the increase of CRP, an additional enhanced CT-scan offered clear discrimination between patients with major abdominal complications and uncomplicated patients. Adequate treatment could then be accomplished.

    The quality of the abstracts presented at a conference reflects the scientific work and level of activity of the scientific association concerned. The aim of the present study was to determine the rate of publications of podium presentations and posters at the conferences of the European Paediatric Orthopaedic Society (EPOS) from 2006 to 2008 and to identify factors that favor publication in peer-reviewed journals. The results are compared with those of other international societies. All 646 abstracts (including podiums, posters, and e-posters) presented at the EPOS conferences were investigated using the PubMed database to identify any corresponding published articles in the journals listed in the database. A period of 5 years before and after the relevant conference was used for the PubMed search. Factors influencing publication and the quality of the study, such as the type of presentation and the level of evidence, were also investigated. A publication rate of 36.7% was observed, corresponding to 237 publications of 646 abstracts. The period to publication showed a mean of 13.88 ± 1.34 months. It was found that abstracts of podium presentations were published significantly more often than poster abstracts (PPediatric Orthopaedics. In addition, the present study shows that abstracts with a higher level of evidence were associated with a higher publication rate. At 36.7%, the rate of publication of EPOS abstracts is within the range reached by other specialist orthopaedics societies, such as the German Society of Orthopaedics and Trauma Surgery (36%) and the British Orthopaedic Association (36%). However, it is lower than the publication rate of the Pediatric Orthopaedic Society of North America (POSNA), at 50%. The high percentage of unpublished conference abstracts (63%), which did not go through a peer-reviewed process, casts doubts upon the practice of utilizing the citation of abstracts based purely on conference abstracts.

    Theodor Emil Kocher (1841-1917), born in Bern, educated in many universities in Europe. Kocher as many surgeons of that time performed orthopedic surgery, general surgery, neurosurgery and endocrine surgery, but he become famous in orthopaedic surgery and endocrine surgery. He is remember as a surgeon who described the approach to the hip joint, elbow joint, maneuver for the reduction of dislocated shoulder joint. He introduced many instruments and many of them, such as Kocher clamp is still in use. Most im
