The attitudes of orthopaedic surgeons regarding radiology reporting is not well-described in the literature. We surveyed Orthopaedic Surgeons in Australia and New Zealand to assess if they routinely review formal radiology reports. An anonymized, 14 question online survey was distributed to consultant surgeons of the Australian and New Zealand Orthopaedic Associations (AOA, NZOA). Two hundred respondents completed the survey (Total number of Fellows: 283 NZOA, 1185 AOA). 18.5% of respondents always reviewed the formal Radiology report, 44.5% most of the time, 35% sometimes and 2% never. By imaging modality, MRI reports were the most frequently reviewed (92%), followed by ultrasound (74%) and nuclear medicine (63%). Only 10% of surgeons consulted formal reports for plain radiography. 55% of surgeons were still likely to disagree with the MRI report, followed by 46% for plain radiography. In cases of disagreement, only 21% of surgeons would always contact the reporting radiologist. The majority of Surgeons (85.5%) think there should be more collaboration between the disciplines, although only 50.5% had regular attendance of a Radiologist at their departmental audit. This survey reveals that the majority of orthopaedic surgeons are not routinely reading radiology reports. This points towards a need for further interdisciplinary collaboration. To our knowledge, this is the first survey directly assessing attitudes of orthopaedic surgeons towards radiology reports.
With associated snow sports injury risks being well documented, the scope for preventative medicine is clear. This article focuses on potential precautions taken by skiers/snowboarders and how they vary between different snow sport groups. A total of 181 randomly selected individuals from the Whistler/Blackcomb Medical Centre, Canada, took part in this questionnaire-based cohort study, examining snow sports activity, preventive measures, and protective equipment use. Most individuals were ski area residents of advanced expertise, with 50% having had a previous snow-riding injury. The most commonly reported significant ski injury was anterior cruciate ligament (ACL) rupture, while in snowboarders, it was wrist fracture. Skiers were more likely to improve fitness levels before going onto the slopes, whereas crossover riders (both skiing and snowboarding) were more likely to take lessons. Most individuals used eye and sun protection and had adequately warm clothing. Beyond basic precautions, protective equipment and preventive measures are used infrequently. It is suggested that by increasing awareness and use of such equipment, injury rates may be reduced.
Although it has long been appreciated that a healthy balanced diet improves health, there is a growing understanding of the way in which certain nutrients can actually improve immune function. Boosting immune function by the use of “immunonutrition” has been shown to improve outcomes, in particular rates of infective complications, in certain groups of surgical patients. In this study we examine the immune status of elderly patients who have suffered a hip fracture and are known to be vulnerable to infection and poor post-operative outcomes to identify specific immune defects associated with this particular cohort. This may allow us to explore the potential benefits of immunonutrition in this group of patients in the future. This was a cohort observational study, in which a series of 16 patients who underwent surgery for hip fractures were followed. The patients were female patients with an age of 60 to 85 years and a mental status questionnaire score of at least 8 out of 10. Immune function was evaluated prior to surgery, on the day following surgery and then at between days 4 and 7 post-operatively. Samples were tested directly ex-vivo using a variety of flow cytometric assays. We report profound loss of innate immune function related specifically to monocyte and granulocyte ability to generate a respiratory burst in response to E.coli uptake persisting up to day 7 post-operatively. In addition, serum cytokine levels indicated very poor T cell function, in identifying these patients as particularly vulnerable to infections.
Surgical reconstruction of the injured Anterior Cruciate Ligament (ACL) is an effective solution to knee instability, but not all grafts incorporate well. The biological environment in the knee that controls graft integration is not well understood, and this study aims to fill that gap as the first step towards a translational approach to optimise outcomes. Over two stages, tissue samples and knee fluid samples were harvested from patients undergoing ACL reconstruction. These samples were cultured and stored to allow batch analysis for a variety of cytokines, growth factors and collagenases. Stage 1 (n=14) identified the presence of specific pro-inflammatory cytokines, growth factors and latent collagenase. Information gathered allowed a more targeted approach to be used in stage 2 (n=18). Stage 2 data from tissue cultures suggest that collagenase activity peaks later than 6 hours post-op. The relationships between collagenase activity and levels of TNF-alpha, IL-1beta and bFGF are of potential interest, and the profiles of patients will be compared with longer term follow-up data to determine any effects on outcomes. Further detailed assessment of the biology of ACL graft incorporation is required, but these preliminary data have clarified some of the details worthy of further study.
Mean IL-6 levels were higher in groups of patients with more distress measured by the DRAM and HADS depression component but were lower in patients with more anxiety. IL-6 receptor levels were higher in patients with raised DRAM and HADS anxiety scores. No significant correlation between questionnaire responses and cytokine levels was found. A correlation exists between IL-6 and CRP levels even at normal levels of CRP.
We have studied 34 consecutive patients receiving Cotrel- Dubousset instrumentation for a single and flexible thoracic scoliotic curve, evaluating the rib hump deformity from a single CT scan through the apical vertebra of the curve. Using two measures of rotation we found a mean improvement of 25% in the rotation of the vertebra after operation. Any, usually minor, deterioration occurred in the first six months postoperatively, and there was no significant further deterioration in 19 patients assessed over two years after surgery. Cotrel-Dubousset instrumentation can produce a significant correction of vertebral rotation and of the associated rib hump deformity.
The nuclide bone-scan will reliably diagnose Perthes' disease with a sensitivity of 0.98 and a specificity of 0.95. The comparable figures for radiographic sensitivity and specificity are respectively 0.92 and 0.78. In addition, it is possible on the scan to recognise the onset of revascularisation of the femoral capital epiphysis some months before there are radiographic signs of new bone formation. Scintigraphy also suggests that in some cases of transient synovitis there may bae a period of reversible ischaemia of the capital epiphysis, which may have relevance to the pathogenesis of Perthes' disease.
