A prospective review of Cauda Equina Syndrome referrals received by an on-call orthopaedic department at a major trauma unit.

INTRODUCTION: Cauda Equina Syndrome (CES) is one of the genuine orthopaedic emergencies. Diagnosis of acute CES is challenging and may be missed, resulting in considerable medicolegal claims. In Ireland, nearly €21 million in compensation has been paid out over a 10-year period due to the diagnosis being missed. As a result, defensive practices have resulted in an increased number of referrals for CES to the on-call orthopaedic service in a major trauma unit. METHODS: A prospective data-capturing exercise was carried out of all referrals for acute CES to the orthopaedic on-call department in a tertiary-level university-affiliated teaching hospital between August and November 2023. Qualitative data was captured including referral source, referring clinician grade, in-hours or out-of-hours referral, MRI on referral, red flags as identified by the referring team, red flags as identified by the orthopaedic team, and outcome. RESULTS: Forty referrals for CES were made over the duration of this audit. Seventeen (42.5%) referrals were made in-hours, and 23 (57.5%) were referred out-of-hours. Only five (12.5%) of these referrals had an MRI done at the time of the referral. No patients were transferred for an out-of-hours MRI to another hospital. Only five (12.5%) patients required surgical decompression-none of these patients required an out-of-hours emergent decompression. CONCLUSION: There is a lack of understanding as to what exactly is being referred-resulting in a referral volume which is over ten times the expected number of CES cases being made to our unit. The lack of out-of-hours MRI access poses a significant concern for patient outcomes.

Surgical helmet systems in total joint arthroplasty: assessment of hood sterility and donning technique.

BACKGROUND: The incidence of prosthetic joint infection (PJI) is increasing, coincident with the rising volume of joint arthroplasty being performed. With recent controversy regarding the efficacy of surgical helmet systems (SHS) in preventing infection, the focus has turned to the correct donning techniques and usage of surgical hoods. The aim of this study was to compare the bacterial contamination of the operating surgeon's gloves after two common donning techniques of SHS hoods. We also evaluated the baseline sterility of the SHS hoods at the beginning of the procedure. METHODS: The bacterial contamination rate was quantified using colony-forming units (CFUs), with 50 trials performed per donning technique. Samples were cultured on 5% Columbia blood agar in ambient air at 37 °C for 48 h and all subsequent bacterial growth was identified using a MALDI-TOF mass spectrometer. In Group 1, the operating surgeon donned their colleague's hood. In Group 2, the operating surgeon had their hood applied by a non-scrubbed colleague. After each trial, the operating surgeon immediately inoculated their gloves onto an agar plate. The immediate sterility of 50 SHS hoods was assessed at two separate zones-the screen (Zone 1) and the neckline (Zone 2). RESULTS: There was no significant difference in contamination rates between the two techniques (3% vs. 2%, P = 0.99) or between right and left glove contamination rates. Immediately after donning, 6/50 (12%) of SHS hoods cultured an organism. Contamination rates at both the face shield and neckline zones were equivalent. The majority of bacteria cultured were Bacillus species. DISCUSSION: We found no significant difference in the operating surgeon's glove contamination using two common SHS hood-donning techniques when they were performed under laminar airflow with late fan activation. We suggest the SHS hood should not be assumed to be completely sterile and that gloves are changed if it is touched intraoperatively.

Increasing hip fracture volume following repeated lockdowns: an Irish multicentre study of periods pre-Covid, during Covid lockdown and following vaccination.

BACKGROUND: Older age groups were identified as a high-risk cohort for Covid-19 and thus were a focus of lockdown measures enacted internationally. Resultant decreased social mobility and physical activity levels are associated with sarcopenia, which may lead to increased risk of hip fracture upon resuming social integration and physical activities after easing of lockdown restrictions. AIMS: Our aim was to compare the incidence of hip fractures during the period following vaccination with subsequent relaxation of restrictions, to those prior to and during the Covid pandemic. METHODS: A multicentre retrospective cohort study was performed consisting of all patients presenting with a "hip" fracture to 3 regional trauma units over the relevant time periods in 2019, 2020 and 2021. Tallaght, Galway and Waterford University Hospitals are large academic teaching hospitals with a combined mixed urban and rural catchment of over 1 million people. FINDINGS: Four-hundred-fourteen patients in total were included in the final analysis, with 133 eligible hip fractures observed proceeding to operative treatment across the study period in 2019, 132 in 2020 and 149 in 2021, representing a 12.88% increase. Demographic data revealed similar patient cohorts with respect to age and gender, fracture pattern and treatment. CONCLUSIONS: An increase in hip fracture volume was observed during the period post vaccination with subsequent relaxation of restrictions and increased social mobility, compared to those prior to and during the Covid pandemic. These findings have implications for hospital planning and orthopaedic resourcing as we navigate our way forward past the Covid-19 Pandemic.

A review of outcomes after operative fixation of clavicular fractures over a 10-year period-a single tertiary trauma unit experience.

BACKGROUND: Early definitive fixation of clavicular fractures is rising in popularity when compared with conservative management. Despite this, the relative risk of subsequent hardware removal or revision surgery is relatively undocumented in the literature. The aim of this study was to review all clavicle fractures treated operatively in a single tertiary referral trauma unit and determine the true incidence of hardware removal and revision rates among this cohort. METHODS: A retrospective electronic review was performed in a single tertiary trauma unit for all open reduction internal fixation of clavicle fractures over 10 years (2010-2019 inclusive). All patients were cross referenced for hardware removal during the same period. Patients identified as having undergone ORIF clavicle were reviewed via the National Integrated Medical Imaging System to identify the fracture pattern, fixation method, radiographic nonunion, or radiographic malunion. Age, gender, time from injury to fixation, and time from insertion to removal of hardware where relevant were also collected. RESULTS: Over the 10-year period from 2010 to 2019, 352 patients underwent ORIF of clavicular fractures. After application of inclusion and exclusion criteria, 346 patients (76% male and 24% female) were analyzed with a mean age of 34.46 years old (95% confidence interval [33.02-35.91]). In total, 54 (15.6%) patients underwent removal of hardware. When fracture type and fixation method were accounted for, only 11% of plate fixations for mid-shaft fractures (n = 29) were removed, whereas 76% of clavicular hook plates for distal fractures (n = 25) underwent removal (P < .001). No distal clavicle fractures treated with locking plates underwent removal (n = 23). Women were almost 3 times more likely to undergo removal of hardware than men (28.6% vs. 11.5%, P < .001). Seven patients (2%) underwent revision ORIF in the 10-year period for nonunion (n = 3), malunion (n = 2), and failure of fixation (n = 2). The mean follow-up time was 1 year (366 days) for those who underwent subsequent surgery and 5.7 years (2087 days) for those who did not. CONCLUSION: Clavicular fracture fixation using either locking or hook plates is a safe method of treatment with a very low reoperation rate for either hardware removal or revision. Women are more likely to request plate removal. Distal locking plates are a safe alternative to hook plates for distal one-third clavicle fractures with lower reoperation rates. Newer techniques are emerging for the management of distal fractures such as tight rope fixation and locking plates which also appear to be successful.

Assessing outcomes in hip fracture patients under the age of 60.

BACKGROUND: Hip fractures are a common and serious orthopaedic injury. The principle of treatment for hip fractures in the "non-elderly" patient is to preserve the native hip. There is limited published literature in this area. AIM: The aim of this research is to review all of the "non-elderly" hip fracture patients to report on the demographics, fracture patterns, fixation types, and revisions. METHODS: This was a retrospective single-site review of all of the "non-elderly" patients who underwent operative management for hip fractures between 1999 and 2019. A manual review was done of all of the x-rays for the identified patients to confirm the fracture type and identify further surgeries. RESULTS: Three hundred and eighty-one patients were identified. The average age was 48.4 years old. Two hundred and thirty nine of them were intra-capsular, and 142 of them were extra-capsular fractures. Dynamic hip screw (DHS) was the most popular fixation method. In the recent decade of data, the number of hemi-arthroplasties remained consistent, but the number of total hip arthroplasties (THAs) performed increased sevenfold. Mean follow-up was 35 months. Forty-three (11%) patients required follow-up surgery. Non-union accounted for 56% of all revisions and avascular necrosis for 19%. THA was performed in 70% of all revisions. CONCLUSION: DHS remains the most widely used fixation technique in an effort to preserve the native hip. The use of THA has increased and surpassed the usage of hemi-arthroplasty in recent times. A high proportion of these patients will go on to develop complications requiring secondary surgery; therefore, they all need long-term follow-up.

Virtual fracture clinic reduces patient X-ray volume for common wrist and ankle fractures.

BACKGROUND: Virtual fracture clinics (VFC) have been widely adopted worldwide as part of the changes in healthcare delivery during the COVID-19 pandemic. They have been shown to be a safe and effective method of delivering trauma care for injuries which do not require immediate intervention or specialist management, whilst maintaining high levels of patient satisfaction. AIMS: Our aim was to evaluate whether VFCs reduce the volume of X-rays performed for common fractures of the wrist and ankle. METHODS: A retrospective cohort review was performed. The pre-VFC group consisted of 168 wrist and 108 ankle referrals from March to September 2019. The VFC group included 75 wrist and 68 ankle referrals, during the period March to September 2020. The total number of X-ray images, carried out within a 3-month period for each fracture was summated, with statistical analysis performed following fracture pattern classification. FINDINGS: A statistically significant decrease in mean X-rays was observed for isolated stable fracture patterns, such as non-displaced distal radius, - 0.976 (p = 0.00025), and Weber A ankle fractures, - 0.907 (p = 0.000013). A reduction was also observed for more complex fracture patterns such as dorsally displaced distal radius, - 0.701 (p = 0.129) and Weber B ankle fractures, - 0.786 (p = 0.235), though not achieving statistical significance. CONCLUSIONS: Virtual fracture clinics can reduce X-ray frequency for common stable wrist and ankle fractures, with resultant benefits for both patients and healthcare systems. These benefits may be sustained in patient care beyond the current COVID-19 pandemic.

Hip fracture surgery within 36 hours reduces both 30-day and 1-year mortality rates.

BACKGROUND AND PURPOSE: Currently the Irish Hip Fracture Standards [IHFS] recommend a Time-to-Surgery [TTS] of within 48 h of admission. The aim of our research is to determine if there was a statistically significant relationship between TTS and 30-day or one-year mortality and to assess whether a 48 h window for surgery is still the most appropriate recommendation. METHODS USED: This was a single-hospital retrospective review of all of the fragility hip fractures between 1st January 2013 and 31st December 2017. Patient demographics were described using descriptive statistics. Dependent variables of interest were 30-day mortality and one-year mortality. Independent predictor variables analysed included age, ASA grade, fracture type, surgery performed, anaesthesia administered, length of stay and TTS (hours as an interval variable), TTS in less than 36 h (binary variable) and TTS in less than 48 h (binary variable). When the significant predictor variables were identified, in order to control for confounder variables, a multivariate regression analysis was performed to identify which predictors were still significantly associated with the outcome variables even after controlling for all other known confounder variables. RESULTS: In total, 806 patients were identified. TTS within 36 h was predictive of a significantly lower 30-day mortality when compared to those undergoing surgery after 36 h (p = 0.031). In contrast, TTS within 48 h did not demonstrate a significantly lower 30-day mortality when compared to those undergoing surgery after 48 h (p = 0.104). On multivariate regression analysis, TTS <36 h (p = 0.011) and age (p < 0.0001) were all independently predictive of 30-day mortality. On multivariate regression analysis, both age (p < 0.0001) and TTS < 36 h (p = 0.002) were significantly predictive of one-year mortality. CONCLUSION: Performing hip fracture surgery within 36 h confers a significant reduction in both 30-day and one-year mortality rates when compared to patients undergoing surgery outside of this time frame. A 36-h window also appears to be superior to a 48-h window because performing surgery within 48 h has no significant impact on the reduction of 30-day mortality rates. We recommend that national guidelines reflect these important findings.

Acetabular Lip Augmentation Devices for the Unstable Total Hip Replacement-A Systematic Review.

BACKGROUND: The optimal management strategy for instability afte total hip arthroplasty remains unclear. Acetabular lip augmentation devices may offer an operative solution for recurrent instability. This systematic review reports the clinical outcomes of acetabular lip augmentation devices in comparison to other treatment options. METHODS: A literature search strategy was performed of Medline, EMBASE, and CENTRAL on September 19, 2020, for all studies reporting outcomes of acetabular lip augmentation devices for recurrent dislocation after total hip arthroplasty. Non-English language articles were excluded. Clinical and survivorship data were collated and analyzed. RESULTS: Thirteen studies describing acetabular augmentation were included for analysis. A total of 644 hips in 636 patients were augmented with a mean age of 75 years (39 to 103). Five different augmentation devices were used. The posterior lip augmentation device (PLAD, DePuy) was the most used (406 hips). Overall, acetabular lip augmentation devices had a 10% postoperative dislocation rate at a mean follow-up of 49 months (0.2 to 132). The PLAD had a 3.9% subsequent dislocation rate with a mean follow-up of 51 months (0.2 to 132). Only one study compared the PLAD to a dual-mobility cup, which demonstrated shorter operative times with the PLAD but higher rates of dislocation and revision surgery. CONCLUSION: The quality of literature on lip acetabular augmentation devices is poor. In these studies, the postoperative dislocation rate after lip acetabular augmentation was relatively high. The PLAD (DePuy) has the most evidence and may offer a therapeutic option for recurrent instability, in very specific clinical situations.

Mode I and II Wear in Ceramic on Ceramic Total Hip Arthroplasty: A Case Report.

INTRODUCTION: Elective total hip arthroplasty (THA) is a common procedure and has been associated with favorable outcomes in both elderly and younger patients. A variety of implant and articular components exist so to allow surgeons to make a patient-specific choice with the intent of maximizing both patient outcomes and implant survival.The utilization of ceramic bearing surfaces during THA has become increasingly prevalent, with their tribological profile conveying favorable wear and osteolysis-resistant properties. Typically, ceramic articulating components are most susceptible to failure through brittle fracture or complications such as squeaking. CASE REPORT: This case describes a 68-year-old Caucasian male who underwent revision of ceramic on ceramic THA due to pain, with intraoperative analysis revealing evidence of gross Mode I acetabular ceramic component wear with a resultant Mode II wear articulation between the ceramic femoral head and acetabular liner. CONCLUSION: Wear between ceramic implants in THA is infrequently reported, and as such awareness of this uncommon phenomena as well as its potential causative factors is important when considering either primary or revision THA involving ceramic bearing components.

Readability of Patient Educational Materials in Pediatric Orthopaedics.

BACKGROUND: Parents are increasingly turning to the internet to seek pediatric health information. Numerous organizations advise that patient educational materials (PEMs) should not surpass the sixth-grade reading level. We aimed to assess the readability of online pediatric orthopaedic PEMs. METHODS: The readability of 176 articles pertaining to pediatric orthopaedics from the American Academy of Orthopaedic Surgeons (AAOS), Pediatric Orthopaedic Society of North America (POSNA), and American Academy of Pediatrics (AAP) websites was assessed with the use of 8 readability formulae: the Flesch-Kincaid Reading Grade Level, the Flesch Reading Ease Score, the Raygor Estimate, the SMOG, the Coleman-Liau, the Fry, the FORCAST, and the Gunning Fog. The mean reading grade level (RGL) of each article was compared with the sixth and eighth-grade reading levels. The mean RGL of each website's articles also was compared. RESULTS: The cumulative mean RGL was 10.2 (range, 6.6 to 16.0). No articles (0%) were written at the sixth-grade reading level, and only 7 articles (4.0%) were written at or below the eighth-grade reading level. The mean RGL was significantly higher than the sixth-grade (95% confidence interval [CI] for the difference, 4.0 to 4.4; p < 0.001) and eighth-grade (95% CI, 2.0 to 2.4; p < 0.001) reading levels. The mean RGL of articles on the POSNA website was significantly lower than the mean RGL of the articles on the AAOS (95% CI, -1.8 to -1.0; p < 0.001) and AAP (95% CI, -2.9 to -1.1; p < 0.001) websites. CONCLUSIONS: Pediatric orthopaedic PEMs that are produced by the AAOS, the POSNA, and the AAP have readability scores that exceed recommendations. Given the increasing preference of parents and adolescents for online health information, the growing body of online PEMs, and the critical role that health literacy plays in patient outcomes, substantial work is required to address the readability of these materials.

Quantifying the impact of the COVID-19 pandemic on orthopaedic trainees: a national perspective.

AIMS: We aim to objectively assess the impact of COVID-19 on mean total operative cases for all indicative procedures (as outlined by the Joint Committee on Surgical Training (JCST)) experienced by orthopaedic trainees in the deanery of the Republic of Ireland. Subjective experiences were reported for each trainee using questionnaires. METHODS: During the first four weeks of the nationwide lockdown due to COVID-19, the objective impact of the pandemic on each trainee's surgical caseload exposure was assessed using data from individual trainee logbook profiles in the deanery of the Republic of Ireland. Independent predictor variables included the trainee grade (ST 3 to 8), the individual trainee, the unit that the logbook was reported from, and the year in which the logbook was recorded. We used the analysis of variance (ANOVA) test to assess for any statistically significant predictor variables. The subjective experience of each trainee was captured using an electronic questionnaire. RESULTS: The mean number of total procedures per trainee over four weeks was 36.8 (7 to 99; standard deviation (SD) 19.67) in 2018, 40.6 (6 to 81; SD 17.90) in 2019, and 18.3 (3 to 65; SD 11.70) during the pandemic of 2020 (p = 0.043). Significant reductions were noted for all elective indicative procedures, including arthroplasty (p = 0.019), osteotomy (p = 0.045), nerve decompression (p = 0.024) and arthroscopy (p = 0.024). In contrast, none of the nine indicative procedures for trauma were reduced. There was a significant inter-unit difference in the mean number of total cases (p = 0.029) and indicative cases (p = 0.0005) per trainee. We noted that 7.69% (n = 3) of trainees contracted COVID-19. CONCLUSION: During the COVID-19 pandemic, the mean number of operative cases per trainee has been significantly reduced for four of the 13 indicative procedures, as outlined by the JCST. Reassignment of trainees to high-volume institutions in the future may be a plausible approach to mitigate significant training deficits in those trainees worst impacted by the reduction in operative exposure.

Readability of Patient Educational Materials in Hip and Knee Arthroplasty: Has a Decade Made a Difference?

BACKGROUND: The Internet has become an increasingly popular resource among orthopedic patients for health education. Numerous organisations recommend that patient educational materials (PEMs) should not exceed the 6th grade reading level. Despite this, studies have repeatedly shown the reading grade level (RGL) of PEMs to be too advanced across a range of surgical specialties. We aimed to determine the readability of online hip and knee arthroplasty PEMs. METHODS: The readability of 134 articles pertaining to hip and knee arthroplasty from 5leading worldwide healthcare websites were assessed, using 8 readability formulae; the Flesch-Kincaid Reading Grade Level, the Flesch Reading Ease Score, Raygor Estimate, SMOG, Coleman-Liau, Fry, FORCAST and Gunning Fog. The mean RGL was compared to the 6th and 8thgrade reading level. The mean RGL of each website was also compared. RESULTS: The mean cumulative RGL was 12 (range = 7-16.1). No articles (0%) were written at a 6th grade reading level and only 4 articles (3%) were written at or below the 8th grade reading level. The mean RGL was significantly higher than the 6th (95% CI, 5.62-6.30; P < .0001) and 8th grade reading level (95% CI, 3.63-4.30; P < .0001). There was a significant difference between the RGLs of the 5websites (P = .001). CONCLUSION: Arthroplasty PEMs produced by leading worldwide healthcare organisations have readability scores that are above the recommended levels. Given the imperative role of health literacy in patient outcomes and satisfaction, and the increasing prevalence of Internet use among orthopedic patients, a substantial amount of work needs to be done to improve the readability of these materials.

The Effectiveness of Negative Pressure Wound Therapy Versus Conventional Dressing in the Treatment of Open Fractures: A Systematic Review and Meta-Analysis.

OBJECTIVES: To compare the efficacy of negative pressure wound therapy (NPWT) versus conventional dressings (CD) in the management of open fractures. DATA SOURCES: A systematic search of English articles in the PubMed/MEDLINE, Embase, and the Cochrane Library through April 2019 comparing NPWT versus CD in the management of open fractures. STUDY SELECTION: Inclusion criteria were articles in English language, comparing NPWT with CD in skeletally mature individuals who had sustained an open fracture at any anatomical site, reporting on rates of deep infection, flap frequency, flap failure, nonunion, amputation, length of hospital, or intensive care unit stay. DATA EXTRACTION: Two authors independently extracted data from selected studies, and the data collected were compared with verify agreement. DATA SYNTHESIS: Pooled odds ratios were calculated for dichotomous outcomes, whereas continuous data were analyzed using the standard weighted mean difference. A random or fixed effect model was used depending on the level of heterogeneity between the studies. CONCLUSIONS: NPWT results in decreased likelihood of deep infection and flap failure compared with CD in the management of open fractures not directly amenable to early closure. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

A healthy decline in age- and sex- specific incidence of hip fractures in the elderly in the Republic of Ireland.

AIM: The number of patients sustaining hip fractures in the Republic of Ireland was expected to increase by 100% from 2004 to 2026. This has not been seen either in local or international literature. Our aim is to assess the age- and sex-specific incidence of hip fractures in patients over the age of 65 years and to determine whether the projected increase in incidence is mirrored in the reality of the Irish experience. METHODS: This is a retrospective observational cohort study including all patients with a hip fracture from a tertiary referral centre from 2005 to 2015. Population data was obtained from the Central Statistics Office of Ireland. RESULTS: 3818 hip fractures in the over 65 age group were recorded. The highest incidence of hip fractures occurred in the 85-90 year old age group. For all ages over 65, the incidence of hip fractures in females over the 10 year period is significantly reducing (p < 0.01). There were 955 hip fractures per 100,000 in females in 2010 and 410 per 100,000 in males. In 2014, this had reduced to 668 in females and 332 in males respectively. CONCLUSION: The annual hip fracture incidence has decreased across both sexes in this study period. This may be associated with preventative measures and introduction of fracture liaison services. This study highlights the importance of investment in preventative strategies for a continued reduction in hip fracture incidence and will help to plan future services.

Changing trends in the mortality rate at 1-year post hip fracture - a systematic review.

BACKGROUND: Traditionally, the mortality rate at 1-year post hip fracture was quoted as approximately 30% of all hip fractures. There have been recent improvements in hip fracture care in the main driven by national hip fracture registries with reductions in 30-d mortality rates reported. AIM: To address recent 1-year post hip fracture mortality rates in the literature. METHODS: Systematic literature review, national hip fracture registries/databases, local studies on hip fracture mortality, 5 years limitation (2013-2017), cohorts > 100, studies in English. Outcome measure: Mortality rate at 1-year post hip fracture. RESULTS: Recent 1-year mortality rates were reviewed using the literature from 8 National Registries and 36 different countries. Recently published 1-year mortality rates appear lower than traditional figures and may represent a downward trend. CONCLUSION: There appears to be a consistent worldwide reduction in mortality at 1-year post hip fracture compared to previously published research. Globally, those which suffer hip fractures may currently be benefiting from the results of approximately 30 years of national registries, rigorous audit processes and international collaboration. The previously quoted mortality rates of 10% at 1-mo and 30% at 1-year may be outdated.

The changing tides of Irish orthopaedic research.

INTRODUCTION: Research is fundamental to bridging theory, practice and education in orthopaedics. Following the restructuring of the surgical training pathway in Ireland, the opportunity to undertake clinical- or lab-based research has fallen. AIMS: Our aim was to investigate the trends of research in orthopaedics and the implications there. METHODS: We reviewed the trend in publications by Irish trauma and orthopaedic (T&O) trainees over the past 20 years across three different classes of journal. We also reviewed the Irish participation in the annual British Orthopaedic Association (BOA) meeting over the past 10 years as well as the rates of abstract submission to the annual Irish Orthopaedic Association (IOA) meeting. RESULTS: We found that publication rates were as follows: JBJS 2005-2010 mean 4.8 vs. 2000-2005 mean 1.6 and 2010-2015 mean 0.2; Injury 2005-2010 mean 3.6 vs. 2000-2005 mean 3.4 and 2010-2015 mean 2.2; IJMS 2010-2015 mean 4.4 vs. 2000-2010 mean 1.1. The number of Irish presentations at the BOA fell from a mean of 5 between 2000 and 2010 to a mean of 1.2 between 2011 and 2017. The rate of IOA abstract submissions compared over the same period has fallen by 21%. We also found that 4% of Irish orthopaedic publications in the IJMS were scientific in nature; this figure was 3.7% of publications in injury and 32.6% in JBJS (UK). CONCLUSIONS: There has been a significant decrease in publication rates by T&O trainees in high-quality journals. There has also been a notable decline in Irish representation at the BOA and a drop in the number of abstract submissions to the IOA. We suggest these findings coincide with the streamlining of surgical training in Ireland, which does not provide for the pursuit in research that is crucial to our practice as clinicians, to the future of our specialty and to the Irish orthopaedic representation internationally.

Incidence and immediate management of genitourinary injuries in pelvic and acetabular trauma: a 10-year retrospective study.

OBJECTIVE: To report the incidence of genitourinary (GU) injuries in pelvic and acetabular (P + A) fractures, to investigate associations between P + A fractures and GU injury patterns, and, as a secondary objective, to evaluate prospectively P + A fracture referrals with regard to adherence to the British Orthopaedic Association Standards for Trauma (BOAST) guidelines over a 12-month period. METHODS: A retrospective review of GU injuries associated with P + A fractures was performed for the period January 2006 to December 2016 in a national pelvic trauma centre in Ireland. Patient demographics, mechanism of injury and details of injuries were recorded. In addition, P + A fracture referrals were prospectively monitored in 2016 and reviewed for adherence to guidelines. RESULTS: The incidence of urological trauma in P + A fractures was 2.4% (n = 28/1 141). The median (range) patient age was 45 (19-85) years and the male to female ratio was 2.1:1. Urethral injuries occurred most frequently (n = 12, 43%), followed by bladder (n = 9, 32%), combined bladder and urethral (n = 3, 11%) and kidney (n = 4, 14%). Bladder and urethral injuries were associated with high-energy pelvic trauma. Renal injuries were associated with acetabular fractures in isolation and in combination with pelvic trauma (P = 0.01). In 2016, there were 175 P + A fracture referrals and 19 patients had suspected urotrauma (visible haematuria, n = 5; non-visible haematuria, n = 2; trauma imaging, n = 11); 9 of these 19 patients had no urological investigations performed. CONCLUSION: In P + A trauma cases GU injuries may be underreported because of inadequate evaluation and diagnostic investigations in these patients. We advocate robust, uniform and guideline-based evaluation of GU injuries in P + A trauma to avoid the significant long-term morbidities that are associated with misdiagnosis.

Development and evaluation of a trauma decision-making simulator in Oculus virtual reality.

BACKGROUND: Consumer-available virtual-reality technology was launched in 2016 with strong foundations in the entertainment-industry. We developed an innovative medical-training simulator on the Oculus™ Gear-VR platform. This novel application was developed utilising internationally recognised Advanced Trauma Life Support (ATLS) principles, requiring decision-making skills for critically-injured virtual-patients. METHODS: Participants were recruited in June, 2016 at a single-centre trauma-course (ATLS, Leinster, Ireland) and trialled the platform. Simulator performances were correlated with individual expertise and course-performance measures. A post-intervention questionnaire relating to validity-aspects was completed. RESULTS: Eighteen(81.8%) eligible-candidates and eleven(84.6%) course-instructors voluntarily participated. The survey-responders mean-age was 38.9(±11.0) years with 80.8% male predominance. The instructor-group caused significantly less fatal-errors (p < 0.050) and proportions of incorrect-decisions (p < 0.050). The VR-hardware and trauma-application's mean ratings were 5.09 and 5.04 out of 7 respectively. Participants reported it was an enjoyable method of learning (median-6.0), the learning platform of choice (median-5.0) and a cost-effective training tool (median-5.0). CONCLUSION: Our research has demonstrated evidence of validity-criteria for a concept application on virtual-reality headsets. We believe that virtual-reality technology is a viable platform for medical-simulation into the future.
