In acute orthopedic trauma care rapid communication between the resident and consultant surgeon is important. Teleradiology and internet facilities have been explained for transferring the x-ray images. Advanced technology found to be impractical for many countries like Sri Lanka. Objective. To determine the applicability of mobile phone multimedia message system (MMS) in acute trauma care to transfer the X-ray images and identify the practical issues related to it. Methodology. A cross sectional survey was done for a period of 01 yr. Digital photos of X-ray images were taken by using a phone camera and communicated between the senior resident and the consultant. MMS images were analyzed in relevant to the, adequacy of MMS images, quality of the MMS image and relevant area of visualization to reach a radiological diagnosis to decide the acute management plan of the patient. Analyzed the issues related to the processing and transmission of MMS Images. Results. 220 X-rays were evaluated. In 93.4 percent times was able to achieve a radiological diagnosis and decide an acute management plan. In 95% of images area of visualization is adequate. Reasons for poor quality images were analyzed. The external factors that determine the quality of the MMS images were identified. The poor quality of MMS images due to illuminator, blurring and cross bars in the MMS image increases the relative risk of achieving radiological diagnosis by factor 1.09, 3.07 and 1.32 respectively. Conclusion. The results suggest that MMS images are useful tool to communicate between consultant and the resident to decide the management plan for the patient in acute trauma care. But still the clinical assessment and on site assessment is the gold standard. Multimedia messages can be used to speed up the management process and helpful when there is time distance between the consultant and the resident

Objectives. to evaluate effect of a dedicated ward for patients with fractured neck of femur on length of acute bed stay and 30 days mortality rate. Design. a retrospective study of two different cohorts of patients with fractured neck of femur, one admitted to a general trauma/surgical ward and the second to a ward dedicated for patients with fractured neck of femur. Setting. a district general hospital affiliated to a University Teaching Foundation Trust. Cohorts. after application of inclusion and exclusion criteria, the first group includes 348 patients who have been diagnosed and admitted with a fractured neck of femur in a 12 months period starting from 01/01/2005. This group have been admitted to a general trauma/surgical ward. The second cohort includes 432 patients who have been diagnosed and admitted with a fractured neck of femur in a 12 months period starting from 01/05/2007. The second group have been admitted into a dedicated ward for patients with fractured neck of femur. Main outcome measures. Lengths of hospital stay in a orthopaedic bed and 30 days mortality rate as main outcome measures. Secondary outcome measures considered to be theatre waiting time and discharge destination improvement. Results. length of acute trauma bed stay has been reduced from 18.3 in the first group to 10.9 (P< 0.01) in the second group. Thirty days mortality rate did not show significant difference (10% vs. 10.8%). There were also some improvements in the secondary outcome measures including reduced theatre waiting time. Conclusion. (with acknowledge of study design limitations) our study has shown a dedicated ward for patients with fractured neck of femur, could shorten acute trauma bed stay, but did not have significant effect on 30 days mortality rate

Symptomatic venous thromboembolism (SVTE) is a potentially significant complication which may occur following injury or surgery. Recent NICE guidelines, and clinical targets have all focused on decreasing in hospital death from acquired SVTE. Despite these guidelines there are no large studies investigating the risk factors for or incidence of SVTE in acute trauma admission. Data from a prospective series of 9167 consecutive patients with a diagnosis of fractured neck of femur (NOF) at a single institution was used to construct a risk score for SVTE. Twenty three factors were screened with pairwise analysis. The cohort had an event rate of 1.4%. A multiple logistic regression model was used to construct a risk score and correct for confounding variables from nine significant factors identified by the pairwise analysis. Four factors; length of stay; chest infection; cardiac failure and transfusion were used to produce the final risk score. The score was statistically significant (p< 0.0001) and highly predictive (ROC analysis, AUC=0.76) of SVTE. The score was separately validated in two cohorts from different Level 1 trauma centres. In one prospective consecutive cohort of 1000 NOF patients all components of the Nottingham SVTE score were found to be individually statistically significant (p< 0.0045). The score was further validated in a separate cohort of 3200 patients undergoing elective hip surgery. The score was found to be statistically significantly predictive of SVTE as a whole, and three of the four components were individually predictive in this patient cohort. Balancing risks and benefits for thromboprophylaxis is key to reducing the risk of thromboembolic events, minimising bleeding and other complications associated with the therapy. Our study of 13,367 prospective patients is the largest of its type and we have successfully constructed and validated a scoring system that can be used to inform patient treatment decisions

Introduction

Virtual fracture clinics (VFCs) are being increasingly used to offer safe and efficient orthopaedic review without the requirement for face-to-face contact. With the onset of the COVID-19 pandemic, we sought to develop an online referral pathway that would allow us to provide definitive orthopaedic management plans and reduce face-to-face contact at the fracture clinics.

Acute spinal cord injury (SCI) is most often secondary to trauma, and frequently presents with associated injuries. A neurological examination is routinely performed during trauma assessment, including through Advanced Trauma Life Support (ATLS). However, there is no standard neurological assessment tool specifically used for trauma patients to detect and characterize SCI during the initial evaluation. The International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) is the most comprehensive and popular tool for assessing SCI, but it is not adapted to the acute trauma patients such that it is not routinely used in that setting. Therefore, the objective is to develop a new tool that can be used routinely in the initial evaluation of trauma patients to detect and characterize acute SCI, while preserving basic principles of the ISNCSCI. The completion rate of the ISCNSCI during the initial evaluation after an acute traumatic SCI was first estimated. Using a modified Delphi technique, we designed the Montreal Acute Classification of Spinal Cord Injuries (MAC-SCI), a new tool to detect and characterize the completeness (grade) and level of SCI in the polytrauma patient. The ability of the MAC-SCI to detect and characterize SCI was validated in a cohort of 35 individuals who have sustained an acute traumatic SCI. The completeness and neurological level of injury (NLI) were assessed by two independent assessors using the MAC-SCI, and compared to those obtained with the ISNCSCI. Only 33% of patients admitted after an acute traumatic SCI had a complete ISNCSCI performed at initial presentation. The MAC-SCI includes 53 of the 134 original elements of the ISNCSCI which is 60% less. There was a 100% concordance between the severity grade derived from the MAC-SCI and from the ISNCSCI. Concordance of the NLI within two levels of that obtained from the ISNCSCI was observed in 100% of patients with the MAC-SCI and within one level in 91% of patients. The ability of the MAC-SCI to discriminate between cervical (C0 to C7) vs. thoracic (T1 to T9) vs. thoraco-lumbar (T10 to L2) vs. lumbosacral (L3 to S5) injuries was 100% with respect to the ISNCSCI. The rate of completion of the ISNCSCI is low at initial presentation after an acute traumatic SCI. The MAC-SCI is a streamlined tool proposed to detect and characterize acute SCI in polytrauma patients, that is specifically adapted to the acute trauma setting. It is accurate for determining the completeness of the SCI and localize the NLI (cervical vs. thoracic vs. lumbar). It could be implemented in the initial trauma assessment protocol to guide the acute management of SCI patients

Discoid meniscus (DM) is a congenital variant of the knee joint that involves morphological and structural deformation, with potential meniscal instability. The prevalence of the Discoid Lateral Meniscus (DLM) is higher among the Asians than among other races, and both knees are often involved. Meniscal pathology is widely prevalent in the adult population, secondary to acute trauma and chronic degeneration. The true prevalence in children remains unknown, as pathologies such as discoid menisci often go undiagnosed, or are only found incidentally. A torn or unstable discoid meniscus can present with symptoms of knee pain, a snapping or clicking sensation and/or a decrease in functional activity, although it is not known if a specific presentation is indicative of a torn DM. While simple radiographs may provide indirect signs of DLM, magnetic resonance imaging (MRI) and arthroscopy is essential for diagnosis and treatment planning. Asymptomatic patients require close follow-up without surgical treatment, while patients with symptoms often require surgery. Partial meniscectomy is currently considered the treatment of choice for DLM. For children are more likely to achieve better results after partial meniscectomy

The purpose of this study was (1) to evaluate the adequacy of informed consent documentation in the trauma setting for distal radius fracture surgery compared with the elective setting for total knee arthroplasty (TKA) at a large public hospital and (2) to explore the relevant guidelines in New Zealand relating to consent documentation. Consecutive adult patients (≥16 years) undergoing operations for distal radius fractures and elective TKA over a 12-month period in a single-centre were retrospectively identified. All medical records were reviewed for the risks and complications recorded. The consent form was analysed using the Flesch Reading Ease Score (FRES) and the Simple Measure of Gobbledygook (SMOG) index readability scores. A total of 133 patients undergoing 134 operations for 135 distal radius fractures and 239 patients undergoing 247 TKA were included. Specific risks of surgery were recorded significantly less frequently for distal radius fractures than TKA (43.3% versus 78.5%, P < 0.001). Significantly fewer risks were recorded in the trauma setting compared to the elective (2.35 ± 2.98 versus 4.95 ± 3.33, P < 0.001). The readability of the consent form was 40.5 using the FRES and 10.9 using the SMOG index, indicating a university undergraduate level of reading. This study has shown poor compliance in documenting risks of surgery during the informed consent process in an acute trauma setting compared to elective arthroplasty. Institutions must prioritise improving documentation of informed consent for orthopaedic trauma patients to ensure a patient-centred approach to healthcare

PFFs are an increasing burden presenting to the acute trauma services. The purpose of this study is to show that cemented revision for Vancouver B2/B3 PFFs is a safe option in the geriatric population, allows early pain-free weight bearing and comparable to a control-group of uncemented stems with regard to return to theatre and revision surgery. A retrospective review was conducted of all PFFs treated in a Level 1 trauma centre from 2015-2020. Follow up x-rays and clinical course through electronic chart was reviewed for 78 cemented revisions and 49 uncemented revisions for PFF. Primary endpoints were all cause revision and return to theatre for any reason. Secondary endpoints recorded mobility status and all-cause mortality. In the cemented group there were 73 Vancouver B2, 5 Vancouver B3 PFF; the mean age was 79.7 years and mean radiological follow-up of 11.9 months. In the cementless group there were 32 Vancouver B2 and 17 Vancouver B3 PFFs; with all 49 patients undergoing distally bearing uncemented revision, the mean age was 72.7 years and mean radiological follow-up of 21.3 months. Patients treated with a cemented prosthesis had significantly higher ASA score (2.94 -v- 2.43, p<0.001). The primary endpoints showed that there was no significant difference in all cause revision 3/78 and 5/49 p=0.077, or return to theatre 13/78 -v- 12/49 p=0.142. Secondary endpoints revealed no significant difference in in-hospital mortality. The cementless group were more likely to be mobilising without any aid at latest follow-up 35/49 -v- 24/78 p<0.001. The use of cemented revision femoral component in the setting of PFFs is one option in the algorithm for management of unstable PFFs according to the Vancouver classification. Evidence from this case-control study, shows that the all-cause revision and return to theatre for any cause was comparable in both groups

Intimate partner violence (IPV) causes significant morbidity and its unlikely to be reported compared to other forms of gender-based violence (GBV). For early detection, understanding Orthopaedic injuries from GBV is vital. This study assesses the pattern of musculoskeletal injuries from GBV and determines the factors associated with it. It is a retrospective observational study of patients aged ≥18 years, with GBV-related acute Orthopaedic injuries. Data was reviewed from January 2021 to December 2021, including, demographic information, soft tissue and bony injuries, relationship to assailant, substance abuse and the day and time of injury. Frequencies and percentages for categorical data were analysed. Chi-square test was used to calculate association. T-test was used to compare groups for continuous & categorical variables. Multivariate analysis was conducted to find the odds ratio and a p-value <0.05 was statistically significant. 138 patients were included, the mean age at presentation being 35.02 years (SD=11). 92.75% of GBV victims were females. Most were unemployed (66.7%). 30.43% (n-42) had a soft tissue injury; superficial laceration being the most common (23.1%), flexor tendon injury (10.87%), hand abscess (5.8%), and extensor tendon injury (5.07%). 71.02 % (n=98) sustained appendicular fractures. 51.45% (n=71) sustained upper limb fractures; distal radius fractures (10.86%) and distal 3rd ulnar fractures (9,42%). 19.57% (n=27) had lower limb fractures; 7.25% (n=10) had lateral malleolus ankle fractures. 63.7% (n=80) of cases were by an intimate partner on weekends (50.73%). 62.31% occurred between 16h00 and 0h00. 41.1% (n=65) reported alcohol abuse. 63.04% had surgery. GBV likely occurs in early middle-aged females by intimate partners influenced by alcohol over the weekends between 16h00 to 0h00. Distal radius/distal 3rd ulnar fractures are the most common bony injuries. Superficial wrist laceration is the commonest soft tissue injury. These findings may assist with early detection and intervention to prevent adverse outcomes in GBV

Aim. Prosthetic joint infection (PJI) represents the second most frequent complication of total joint arthroplasty (TJA) with up to 20% of low-grade PJI treated as aseptic failure. Sensitive diagnostic criteria have been provided by EBJIS. However, to date there is no single test to reliably diagnose all PJIs. Studies of Mazzucco et al. and Fu et al. suggest that synovial fluid (SF) viscosity could be considered as an important marker for PJI. The primary aim of our study was to determine if SF viscosity is a more reliable diagnostic criterion of PJI than the SF cell count with differential (CCD), and the combined diagnostic value of SF viscosity and CCD. Method. We prospectively analysed the viscosity of SF samples obtained during TJA of hip and knee revisions. We sampled 2.5–5mL of SF for viscosity and CCD. Intraoperatively, 1mL of the sample was analysed for the CCD. The remaining SF was centrifuged for 4min at 7000rpm. The viscosity of the supernatant was determined on Ostwald viscometer as the time required to pass the viscometer at 20°C. During each surgery at least 5 microbiological and multiple histopathological samples were harvested, and explant sonication was performed. The diagnosis was based on EBJIS definition. The viscosity threshold for detecting PJI was set at 65 seconds. Results. Between December 2020 and January 2023, we analysed 65 knee and 47 hip TJA revision procedures. There were 55 septic and 57 aseptic diagnoses. As a diagnostic marker of PJI, SF viscosity achieved 100% sensitivity and 82.5% specificity, with area under the receiver operating characteristic curve (AUC) of 0.832 (95% CI 0.739, 0.925). The specificity and sensitivity of SF CCD were 98.2% and 78.2%, respectively, with AUC of 0.921 (95% CI 0.869, 0.974). Of the 10 cases incorrectly diagnosed as aseptic based on SF viscosity, 2 were acute traumas and 8 metalloses. The SF CCD in all these cases was <0.5. Of the 12 cases incorrectly diagnosed as aseptic based on SF CCD, 6 cases were culture negative, 4 C. acnes and 2 S. epidemidis isolates in microbiology. Taken together, SF viscosity and CCD achieved a combined AUC of 0.953 (95% CI 0.919, 0.987). Conclusions. Our study is the first to report that SF viscosity is more sensitive but slightly less specific for PJI than SF CCD. The study demonstrates diagnostic value of combining SF viscosity with CCD in decision making in TJA revision surgery

Introduction. Fracture related infections (FRI) following intramedullary nailing for tibial shaft fractures remain challenging to treat with associated high patient morbidity and healthcare costs. Recently, antibiotic-coated nails have been introduced as a strategy to reduce implant related infection rates in high-risk patients. We present the largest single-centre case series on ETN PROtect® outcomes reporting on fracture union, infection rates and treatment complications. Materials and Methods. 56 adult patients underwent surgery with ETN PROtect® between 01/09/17 and 31/12/20. Indications consisted of acute open fractures and complex revision cases (FRI, non-union surgery and re-fracture) with a mean of 3 prior surgical interventions. 51 patients had an open fracture as their index injury. We report on patient characteristics and outcomes including radiological/clinical union and deep infection. The one-year minimum follow-up rate was 87.5%. Results. One (1.8%) patient developed a deep surgical infection and associated non-union requiring further surgery. In addition, we identified three cases (5.4%) of aseptic non-union following facture treatment with ETN PROtect®. Of the 5 patients who underwent staged complex revision surgery for established FRI with ETN PROtect®, all had treatment failure with ongoing symptoms of deep infection requiring further treatment. Conclusions. Use of the ETN PROtect® nail in high-risk patients in the acute trauma setting demonstrates promising outcomes in the prevention of implant-related infection. In our limited series we have failed to observe any benefit over uncoated nails, when used in treating cases of established FRI/osteomyelitis and would therefore advise caution in their use, especially in view of the high cost

The external fixator is an invaluable device when treating acute complex trauma and in limb reconstruction. It is therefore important to ensure its efficient and safe application to avoid complications. A lot of research has been done to evaluate the factors around external fixator stability, pin site infections and more is still being done to understand pin loosening. The purpose of this study was to evaluate other factors that may contribute in external fixator pin loosening. The aim was to evaluate if the different Schanz pin insertion techniques contribute to pin loosening. Two tibia diaphyses from two cadavers were each divided into three sections. Three different drilling techniques were repeated in each of the sections. A total of 36 Schanz pins were inserted and a section cut out of the bone in front of the pins was done allowing visual inspection of the pin hole for features of thread stripping. These features were predefined as thread pattern disruption, smoothening and shallow imprint on the cortex. Evidence of pin thread stripping was seen in all of the pin insertion techniques. The first method where the hole was pre-drilled and pin inserted with the drill showed 100% thread stripping. The second method of pre-drilling and hand insertion showed the least amount with 16.7% of pin stripping noted and 66.7% pin thread stripping was observed when inserting the pin with power without pre-drilling the pilot hole using the third method. Different pin insertion techniques result in varying amounts of pin thread stripping. The most amount of thread stripping occurs when a Schanz pin is inserted with power after pre-drilling. This finding, although not measured scientifically, supports the current recommendation of pre-drilling and manual insertion of the pin. In future, more scientific measurement are necessary to quantify these findings and assess their clinical significance

We completed a retrospective case study of 66 consecutive isolated closed 5. th. metacarpal neck fractures that presented to our Hospital between September 2009 and March 2010. Their management was established by referring to outpatient letters and A&E notes. The aim of the study was to establish if it would be more efficient and cost effective for these patients to be managed in A&E review clinic without compromising patient care. Of these 66 patients, 56 were males and the mean age was 26 years (12–88 years). Four fractures were not followed up at our Trust, six did not attend their outpatient appointment, one did not require follow up. Of the remaining 55, reviewed at a fracture clinic, all but two were managed conservatively, with 47% requiring one outpatient appointment only. The cost of a new patient Orthopaedic outpatient appointment is £180 with subsequent follow up appointments costing £80 per visit, in contrast to an A&E review clinic appointment at a cost of £60. In view of the small percentage in need of surgical intervention: we highlight the possibility for these patients to be managed solely in the A&E department with a management plan made at the A&E review clinic with an option to refer patients if necessary, and the provision of management guidelines and care quality assurance measures. This, we believe, would maintain care quality for these patients, improve efficiency of fracture clinics and decrease cost. We calculate that even if only all the patients that required one follow up appointment could have been managed by A&E alone then the saving to the local health commissioning body over a six month period from within our trust alone, would have been £3000, which across all trusts providing acute trauma services within the NHS would amount to a substantial saving nationwide

Objective. To investigate the effects of trauma and fracture surgery on leukocyte maturation and function. Background. Unbalanced inflammation triggered by trauma has been linked to multiorgan dysfunction (MOD) and death. In animal and cellular models, changes in neutrophil function and failure of monocyte infiltration and resolution have been implicated as possible causes. The investigators combine assays on neutrophil function with surface antigen expression on circulating neutrophils and monocytes. These are correlated with severity of traumatic injury, type of surgery and clinical outcome to help explain the aetiology of distant organ injury, and pose a case for damage control surgery. Results. A total of 20 patients requiring internal fixation of femoral shaft fractures, acetabular fractures and pelvic fractures were recruited. Those undergoing surgery following an interval period were used as control, with blood and plasma samples pre-operatively, and 2 and 5 days post-operatively, whilst patients with acute trauma also had an admission sample. Using flow cytometry, the neutrophils were gated on CD15+ CD14- with high side scatter whilst the monocytes were gated on CD14+ CD15- with low side scatter. Two days following surgery the neutrophils showed reduced CXCR2 expression and increased CXCR1, CD11b and IL-6R expression whilst the monocytes showed reduced CCR2 and HLA-DR receptor expression. The change in receptor expression was enhanced in the trauma patients in comparison to the control patients, and correlated with cellular function, using respiratory burst, elastase release and transmigration assays. Conclusions. This first human trial evaluating the immunologic/anti-inflammatory effects of trauma and trauma surgery on the specific antigen expression helps explain one mechanism for organ damage in the post-trauma patient

Autologous cell therapy using stem cells and progenitor cells is considered to be a popular approach in regenerative medicine for the repair and regeneration of tissue and organs. In orthopaedic practice, autologous cell therapy has become a major focus, particularly, as a feasible treatment for tendon injury. Tendons are dense connective tissue that bridge bone to muscle and transmit forces between muscle and bone to maintain mechanical movement. Tendons are poorly vascularised and have very little capacity to self-regenerate. Degeneration of tendon is often caused by injury. The pathogenesis of tendon injury, commonly known as tendinosis, is not an inflammatory condition but is secondary to degenerative changes, including disruption of the collagen matrix, calcification, vascularisation and adipogenesis. The aetiology of tendinosis is considered to be multifactorial and the pathogenesis is still unclear. Intrinsic factors such as a lack of blood and nutrition supply and extrinsic factors such as acute trauma and overuse injury caused by repetitive strain, have been implicated as contributors to the pathogenesis of tendinosis. More recent studies suggest that programmed tendon cell death (tenocyte apoptosis) may play a major role in the development of tendinosis. Such cellular abnormalities may influence the capacity of tendon to maintain its integrity. Traditional treatments such as anti-inflammatory drugs, steroid injections and physiotherapy are aimed at symptom relief and do not address the underlying pathological changes of degeneration. Here, we propose that autologous cell therapy may be an innovative and promising treatment for tendon injury. We will present evidence that suggest that autologous tendon cell therapy may be feasible to repair and regenerate tendon. We will also present data summarising the preclinical evaluation of autologous tendon cell therapy in animal models and the safety and tolerability of autologous tendon cell therapy in humans in studies, which are currently conducted at the Centre for Orthopaedic Research at the University of Western Australia

Aims

The aim of this study was to surveil whether the standard operating procedure created for the NHS Golden Jubilee sufficiently managed COVID-19 risk to allow safe resumption of elective orthopaedic surgery.

Aims

Europe has found itself at the epicentre of the COVID-19 pandemic. Naturally, this has placed added strain onto healthcare systems internationally. It was feared that the impact of the COVID-19 pandemic could overrun the Irish healthcare system. As such, the Irish government opted to introduce a national lockdown on the 27 March 2020 in an attempt to stem the flow of admissions to hospitals. Similar lockdowns in the UK and New Zealand have resulted in reduced emergency department presentations and trauma admissions. The aim of this study is to assess the effect of the national lockdown on trauma presentations to a model-3 hospital in Dublin, Ireland.

Aims

The aim of this study is to determine the effects of the UK lockdown during the COVID-19 pandemic on the orthopaedic admissions, operations, training opportunities, and theatre efficiency in a large district general hospital.
