Abstract. Introduction. Skeletal muscle wasting is an important clinical issue following acute traumatic injury, and can delay recovery and cause permanent functional disability particularly in the elderly. However, the fundamental mechanisms involved in trauma-induced muscle wasting remain poorly defined and therapeutic interventions are limited. Objectives. To characterise local and systemic mediators of skeletal muscle wasting in elderly patients following acute trauma. Methods. Experiments were approved by a local NHS Research Ethics Committee and all participants provided written informed consent. Vastus lateralis biopsies and serum samples were taken from human male and female patients shortly after acute trauma injury in lower limbs (n=6; mean age 78.7±4.4 y) and compared to age-matched controls (n=6; mean age 72.6±6.3 y). Atrogenes and upstream regulators (MuRF1; MAFbx; IL6, TNFα, PGC-1α) mRNA expression was assessed in muscle samples via RT-qPCR. Serum profiling of inflammatory markers (e.g. IL6, TNFα, IL1β) was further performed via multiplex assays. To determine whether systemic factors induced by trauma directly affect muscle phenotype, differentiated primary human myotubes were treated in vitro with serum from controls or trauma patients (pooled; n=3 each) in the final 24 hours of differentiation. Cells were then fixed, stained for myogenin and imaged to determine minimum ferret diameter. Statistical significance was determined at P<0.05. Results. There was an increase in skeletal muscle mRNA expression for E3 ligase MAFbx and inflammatory cytokine IL-6 (4.6 and 21.5-fold respectively; P<0.05) in trauma patients compared to controls. Expression of myogenic determination factor MyoD and regulator of mitochondrial biogenesis PGC-1α was lower in muscle of trauma patients vs controls (0.5 and 0.39-fold respectively; P<0.05). In serum, trauma patients showed increased concentrations of circulating pro-inflammatory cytokines IL-6 (14.5 vs. 0.3 pg/ml; P<0.05) and IL-16 (182.7 vs. 85.2 pg/ml; P<0.05) compared to controls. Primary myotube experiments revealed serum from trauma patients induced atrophy (32% decrease in diameter) compared to control serum-treated cells (P<0.001). Conclusion. Skeletal muscle from patients following acute trauma injury showed greater expression of atrophy and inflammatory markers. Trauma patient serum exhibited higher circulating pro-inflammatory cytokine concentrations. Primary human myotubes treated with serum from trauma patients showed significant atrophy compared to healthy serum-treated controls. We speculate a mechanism(s) acting via circulating factors may contribute to skeletal muscle pathology following acute trauma. Declaration of Interest.

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

Aims. The aims of this study were to identify and evaluate the current literature examining the prognostic factors which are associated with failure of total elbow arthroplasty (TEA). Methods. Electronic literature searches were conducted using MEDLINE, Embase, PubMed, and Cochrane. All studies reporting prognostic estimates for factors associated with the revision of a primary TEA were included. The risk of bias was assessed using the Quality In Prognosis Studies (QUIPS) tool, and the quality of evidence was assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework. Due to low quality of the evidence and the heterogeneous nature of the studies, a narrative synthesis was used. Results. A total of 19 studies met the inclusion criteria, investigating 28 possible prognostic factors. Most QUIPS domains (84%) were rated as moderate to high risk of bias. The quality of the evidence was low or very low for all prognostic factors. In low-quality evidence, prognostic factors with consistent associations with failure of TEA in more than one study were: the sequelae of trauma leading to TEA, either independently or combined with acute trauma, and male sex. Several other studies investigating sex reported no association. The evidence for other factors was of very low quality and mostly involved exploratory studies. Conclusion. The current evidence investigating the prognostic factors associated with failure of TEA is of low or very low quality, and studies generally have a moderate to high risk of bias. Prognostic factors are subject to uncertainty, should be interpreted with caution, and are of little clinical value. Higher-quality evidence is required to determine robust prognostic factors for failure of TEA. Cite this article: Bone Joint Res 2024;13(5):201–213

Aims. The aim of this study was to review the provision of total elbow arthroplasties (TEAs) in England, including the incidence, the characteristics of the patients and the service providers, the types of implant, and the outcomes. Methods. We analyzed the primary TEAs recorded in the National Joint Registry (NJR) between April 2012 and December 2022, with mortality data from the Civil Registration of Deaths dataset. Linkage with Hospital Episode Statistics-Admitted Patient Care (HES-APC) data provided further information not collected by the NJR. The incidences were calculated using estimations of the populations from the Office for National Statistics. The annual number of TEAs performed by surgeons and hospitals was analyzed on a national and regional basis. Results. A total of 3,891 primary TEAs were included. The annual incidence of TEA was between 0.72 and 0.82 per 100,000 persons before 2020 and declined to 0.4 due to a decrease in elective TEAs during the COVID-19 pandemic, with a slight recovery in 2022. Older patients, those of white ethnicity and females, were more likely to undergo TEA. Those who underwent elective TEA had a median wait of between 89 (IQR 41 to 221) and 122 days (IQR 74 to 189) in the years before 2021, and this increased to 183 days (IQR 66 to 350) in 2021. The number of TEAs performed by surgeons per annum remained unchanged, with a median of two (IQR 1 to 3). The median annual number of TEAs per region was three to six times higher than the median annual case load of the highest volume hospital in a region. Patients in the lowest socioeconomic group had a higher rate of serious adverse events and mortality (11%) when undergoing TEA for acute trauma. Conclusion. In England, TEA is more common in older age groups, those of white ethnicity, and females. The COVID-19 pandemic affected the incidence of elective TEA and waiting times, and the provision of TEA has not yet recovered. The Getting it Right First Time recommendation of centralizing services to one centre per region could result in up to a six-fold increase in the number of TEAs being performed in some centres.

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

Aim. Fractures are the second commonest presentation of non-accidental injury (NAI) in children. Approximately one third of abused children will present to Acute Trauma Services (ATS) with fractures. Any cases of suspected child maltreatment should be referred to Safeguarding Services for follow-up, as outlined by Trust Guidelines. Our aim was to examine the referral of children with suspicious fractures to safeguarding and assess if cases with high risk of abuse are being missed by ATS. Method. A comprehensive literature review identified commonly cited indicators of abuse. Inclusion criteria included age less than 18 months seen in A&E or Fracture Clinic with a long bone fracture. Patient notes were analysed to identify occurrence of these risk factors and findings cross-referenced with Safeguarding Services' records to verify whether high-risk patients were detected. The origin of each referral was also noted. Results. The cohort consisted of 28 patients, nine had records with Safeguarding Services. The remaining 19 were not thought to be at significant risk to alert Safeguarding and have not subsequently come to their attention due to physical abuse. An average of two risk factors was seen (range 1–5) and the patient with five risk factors was investigated by Safeguarding. The most common risk factors were ‘unclear mechanism of injury’ and ‘un-witnessed injury’. The most specific for abuse were ‘suspicious history’ and ‘previous injury’. Out of five patients with metaphyseal fractures, only one was known to Safeguarding Services. The remaining four patients had relatively few risk factors. Conclusion. Children with the highest number of risk factors were detected and referred to Safeguarding. Some with few risk factors were also referred, suggesting ATS are sensitive to signs of abuse in a clinical history. Our study indicates metaphyseal fractures are not necessarily highly predictive of NAI and may be related to patients' ages

Purpose of study: This study assessed the current availability of “out of hours” MRI scans for patients who present with symptoms suggestive of cauda equina syndrome to trauma units across the United Kingdom (UK). Methods: 98 trauma units in 212 hospitals across the UK were identified. Senior house officers and registrars were questioned about the availability of emergency MRI scans after 5pm and midnight and at weekends. All units responded to the survey. Results: 88 of 98 units had an on-site MRI scanner. In 32 hospitals, an MRI scan could be obtained after 5pm. In only 27 hospitals was this possible after midnight. In 58 units (65%) of cases, consultant to consultant contact was required to arrange the scan. 67 units found it “very difficult” or “impossible” to obtain an MRI scan at the weekend producing a potential delay of 64 hours from presentation at 5pm on a Friday night to 9am on a Monday morning. Conclusions: The availability of urgent MRI scans in cases of suspected cauda equina syndrome currently represents a “postcode lottery” across the UK. This may mean that patients requiring urgent surgical decompression face a significant delay in diagnosis. Delayed or missed cases of cauda equina syndrome have huge personal, social and economic impact. On-site MRI facilities, which are available 24 hours a day for such cases are recommended in all units receiving an acute trauma on call

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.

To assess whether the ATLS guidelines were being followed within the Accident and Emergency department of a major DGH and suggest a protocol for assessment in future cases.

The case records and original X-rays of one hundred sequential patients presenting to the Royal Gwent Hospital who received cervical spine x-rays were reviewed retrospectively. Data sets were recorded for each patient including mechanism of injury, recorded opinion of the cervical spine film, diagnosis within the accident and emergency and discharge or admission. The cervical spine films were then reviewed by the authors and assessed for adequacy of visualisation of the C7-T1 junction as required by the ATLS guidelines.

Of the 100 patients 34 of the films assessed were found to have inadequate visualisation of the C7-T1 junction as required by the ATLS guidelines. Swimmers’ views had been obtained in 12 of these patients. The age range was from 9 to 83 years of age.

21 of the 34 had been involved in Road traffic Accidents, 7 in falls, 4 in sport, 1 in an assault and 1 was a case of spontaneous onset neck pain. Diagnoses included neck sprain in 17 cases, bruising in 3 cases, and whiplash in 3 cases. No diagnosis was offered in 11 cases. No specialist opinion was obtained for any of the 34 cases who received inadequate visualisation of their cervical spine. 56 of the 100 patients had satisfactory visualisation of the C7-T1 junction. Films were unavailable for 9 patients.

Visualisation of C7-T1 acute cervical trauma can be difficult. The use of swimmers’ views is a helpful adjunct but these can be difficult to interpret. In the absence of adequate visualisation of the C7-T1 junction injury cannot be excluded. A specialist or senior opinion should be sought with recourse to CT or MRI imaging if cervical spine pathology is suspected, but not excluded with initial radiographs.

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

Introduction. Severe, multiplanar, fixed, pantalar deformities present a challenge to orthopaedic surgeons. Surgical options include limb salvage or amputation. This study compares outcomes of patients with such deformities undergoing limb preservation with either pantalar fusion (PTF) or talectomy and tibiocalcaneal fusion (TCF), versus below knee amputation (BKA). Methods. Fifty-one patients undergoing either PTF, TCF and BKA for failed management of severe pantalar deformity were evaluated retrospectively. Twenty-seven patients underwent PTF, 8 TCF and 16 BKA. Median age at surgery was 55.0 years (17 to 72 years) and median follow-up duration was 49.9 months (18.0 to 253.7 months). Patients with chronic regional pain syndrome, tumour, acute trauma or diabetic Charcot arthropathy were excluded. Clinical evaluation was undertaken using the MOxFQ, EQ-5D and Special Interest Group in Amputee Medicine score (SIGAM). Patients were also asked whether they were satisfied with their surgical outcome and whether they would have the same surgery again. Results. There was no statistically significant difference in patient reported outcomes, satisfaction, or complication profile between the groups. Twenty-two patients undergoing PTF (81.5%), 6 patients undergoing TCF (75%), and 15 patients undergoing BKA (93.8%) were satisfied overall (p=0.414). Similarly, there was no difference in the proportion of patients who would opt for the same procedure again (p=0.142): 23 in the PTF group (85.2%), 8 in the TCF group (100%), and 11 in the BKA group (68.8%). Seven patients undergoing PTF (25.9%), 2 patients undergoing TCF (25%) and 6 patients undergoing BKA (37.5%) had major complications (p=0.692). Conclusion. This study has shown that PTF, TCF and BKA can all provide an acceptable outcome in treatment of severe, degenerative deformities of the lower extremity. Therefore, surgical decisions must be based on individual patient considerations. This data may also be useful in counselling patients when considering limb salvage versus amputation for severe deformity

Electronic Health Records (EHRs) have benefits for hospitals and uptake in the UK is increasing. The National Joint Registry (NJR) monitors implant and surgeon performance and relies on accuracy of data. NJR data are used for identification of potential outliers for both mortality and revision; analyses are adjusted for age, sex, and American Society of Anaesthesiologists score (ASA) and cases with some indications are excluded from analyses. In October 2020, the Royal Devon University Hospitals NHS Foundation Trust “went live” on an EHR, almost eradicating paper from the Trust. This included stopping use of paper NJR forms by creating a bespoke electronic template. We sought to identify discrepancies between operation notes and data input to the NJR in variables that may influence potential outlier analyses. Data input to the NJR from 15/10/2020 to 18/10/2022 for hip procedures were provided by NEC Software Solutions. NJR data were compared to those recorded on operation notes. There were 1067 hip procedures recorded in the NJR (946 primary THRs). Of the primary THRs, discrepancies in indication between NJR and operation note were identified in 139 (15%) cases. Common discrepancies included cases being recorded as osteoarthritis where the true indication was acute trauma (n=63), avascular necrosis (n=14), metastatic cancer/malignancy (n=6) and 21 cases with no recorded indication. We identified 88 cases where the ASA recorded in the NJR differed from the anaesthetic chart. Other inaccuracies were identified including 23 cases missing type of procedure (e.g., primary or revision) and one where revision surgery had been recorded as primary. We identified at least 83 cases that should have been excluded from NJR mortality analyses but were not. Given the low incidence of mortality following primary THR, these cases (with increased risk of death) have the potential to incorrectly identify the hospital as a potential outlier. Discrepancies in ASA may also impact on both revision and mortality outlier calculations. We urge caution to hospitals in the implementation of EHRs and advise regular audit of data sent to the NJR

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

Bone defects can result from different incidents such as acute trauma, infection or tumor resection. While in most instances bone healing can be achieved given the tissue's innate ability of self-repair, for critical-sized defects spontaneous regeneration is less likely to occur, therefore requiring surgical intervention. Current clinical procedures have failed to adequately address this issue. For this reason, bone tissue engineering (BTE) strategies involving the use of synthetic grafts for replacing damaged bone and promoting the tissue's regeneration are being investigated. The electrical stimulation (ES) of bone defects using direct current has yielded very promising results, with neo tissue formation being achieved in the target sites in vivo. Electroactive implantable scaffolds comprised by conductive biomaterials could be used to assist this kind of therapy by either directing the ES specifically to the damaged site or promoting the integration of electrodes within the bone tissue as a coating. In this study, we developed novel conductive heat-treated polyacrylonitrile/poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PAN/PEDOT:PSS) nanofibers via electrospinning capable of mimicking key native features of the bone tissue's extracellular matrix (ECM) and providing a platform for the delivery of exogenous ES. The developed scaffolds were doped with sulfuric acid and mineralized in Simulated Body Fluid to mimic the inorganic phase of bone ECM. As expected, the doped PAN/PEDOT:PSS nanofibers exhibited electroconductive properties and were able to preserve their fibrous structure. The addition of PEDOT:PSS was found to improve the bioactivity of the scaffolds, with a more significant in vitro mineralization being obtained. By seeding the scaffolds with MG-63 osteoblasts and human mesenchymal stem/stromal cells, an increased cell proliferation was observed for the mineralized PAN/PEDOT:PSS nanofibers, which also registered an increased expression of key osteogenic markers (e.g Osteopontin). Our findings appear to corroborate the promising potential of the generated nanofibers for future ES-based BTE applications.
