There is limited literature on the effects of socioeconomic factors on outcomes after total ankle arthroplasty (TAA). In the setting of hip or knee arthroplasty, patients of a lower socioeconomic status demonstrate poorer post-operative satisfaction, longer lengths of stay, and larger functional limitations. It is important to ascertain whether this phenomenon is present in ankle arthritis patients. This is the first study to address the weight of potential socioeconomic factors in affecting various socioeconomic classes, in terms of how they benefit from ankle arthroplasty. This is retrospective cohort study of 447 patients who underwent a TAA. Primary outcomes included pre-operative and final follow-up AAOS pain, AAOS disability, and SF-36 scores. We then used postal codes to determine median household income using Canadian 2015 census data. Incomes were divided into five groups based on equal amounts over the range of incomes. This method has been used to study medical conditions such as COPD and cardiac disease. These income groups were then compared for differences in outcome measures. Statistical analysis was done using unpaired t-test. A total of 447 patients were divided into quintiles by income. From lowest income to highest income, the groups had 54, 207, 86, 64, and 36 patients, respectively. The average time from surgery to final follow up was 85.6 months. Interestingly, we found that patients within the middle household income groups had significantly lower AAOS disability scores compared to the lowest income groups at final follow-up (26.41 vs 35.70, p=0.035). Furthermore, there was a trend towards middle income households and lower post-operative AAOS pain scores compared to the lowest income group (19.57 vs 26.65, p=0.063). There was also a trend toward poorer AAOS disability scores when comparing middle income groups to high income groups post-operatively (26.41 vs 32.27, p=0.058). Pre-operatively, patients within the middle-income group had more pain, compared to the lowest and the highest income groups. No significant differences in SF-36 scores were observed. There were no significant differences seen in middle income groups compared to the highest income group for AAOS pain post-operatively. There were no significant differences found in pre-operative AAOS disability score between income groups. Patients from middle income groups who have undergone TAA demonstrate poorer function and possibly more pain, compared to lower and higher income groups. This suggests that TAA is a viable option for lower socioeconomic groups and should not be a source of discouragement for surgeons. In this circumstance there is no real disparity between the rich and the poor. Further investigation is needed to explore reasons for diminished performance in middle class patients

We aimed to identify whether patients in lower socioeconomic groups had worse function prior to total knee arthroplasty and to establish whether these patients had worse post-operative outcome following total knee arthroplasty. Data were obtained from the Kinemax outcome study, a prospective observational study of 974 patients undergoing primary total knee arthroplasty for osteoarthritis. The study was undertaken in thirteen centres, four in the United States, six in the United Kingdom, two in Australia and one in Canada. Pre-operative data were collected within six weeks of surgery and patients were followed for two years post-operatively. Pre-operative details of the patient's demographics, socioeconomic status (education and income), height, weight and co-morbid conditions were obtained. The WOMAC and SF-36 scores were also obtained. Multivariate regression was utilised to analyse the association between socioeconomic status and the patient's pre-operative scores and post-operative outcome. During the analysis, we were able to control for variables that have previously been shown to effect pre-operative scores and post-operative outcome. Patients with a lower income had a significantly worse pre-operative WOMAC pain (p=0.021) and function score (p=0.039) than those with higher incomes. However, income did not have a significant impact on outcome except for WOMAC Pain at 12-months (p=0.014). At all the other post-operative assessment times, there was no correlation between income and WOMAC Pain and WOMAC Function. Level of education did not correlate with pre-operative scores or with outcome at any time during follow-up. This study demonstrates that across all four countries, patients with lower incomes appear to have a greater need for total knee arthroplasty. However, level of income and educational status did not appear to affect the final outcome following total knee arthroplasty. Patients with lower incomes appear able to compensate for their worse pre-operative score and obtain similar outcomes post-operatively

INTRODUCTION. Utilization of a patient management support system in our clinical pathway has been successfully demonstrated to both reduce the length of hospital stay after primary THA, as well as reducing the number of hospital readmissions. While successful in a general patient population, the ability of a patient management support system to reduce readmissions in subsets of high risk THA patients has not been evaluated. METHODS. We identified all primary THAs performed at a single institution between 2013 and 2015. Patient sex, age at the time of surgery, race, ASA grade, and 120-day readmissions were retrieved from the patient medical record. Similar to previous studies, the patient's home address was used as a proxy for socioeconomic status, with the estimated median income of a given patient being estimated as the median household income for patients of similar ethnicity living within their zip code as reported in the 2014 U.S. Census. A binary regression was used to determine if a model of patient factors (age, sex, race, socioeconomic status, and/or ASA grade) could accurately predict 120-day readmission after primary THA. Age and socioeconomic status were treated as a continuous variable and all other factors were categorical in nature, and the individual effects of each categorical factor on readmissions were also assessed. RESULTS. A sample of 889 primary THAs was identified using the above criteria, of which 754 (84.8%) were Caucasian and 124 (13.9%) were African Americans. Eleven patients (1.2%) either self-reported a different race or race was unknown. Due to the small number of patients in the other/unknown group, this subset was not included in our analysis. With the remaining sample of 878 THAs (475 females, 403 males; age 62.1 ± 13.0 years), a model containing age, sex, race, socioeconomic status, and ASA grade was unable to accurately predict the need for hospital readmission (R2 = 0.02). When assessed individually, the rates of hospital readmission did not differ by sex or race; however, those with ASA grades I or II had significantly lower readmission rates than patients with ASA grades III or IV (Table 1). DISCUSSION AND CONCLUSION. Despite a comprehensive program, the risk of readmission for patients with greater comorbidity burdens was double that of patients with low ASA grades

Radial head fractures are common and mainly require a functional conservative treatment. About 20% of patients will present an unsatisfactory final functional result. There is, however, little data allowing us to predict which patients are at risk of bad evolve. This makes it difficult to optimize our therapeutic strategies in these patients. The aim of this study is to determine the personal and environmental factors that influence the functional prognosis of patients with a radial head fracture. We realized over a 1-year period a prospective observational longitudinal cohort study including 125 consecutive patients referred for a fracture of the radial head in a tertiary trauma center. We originally collected the factors believed to be prognostic indicators: age, sex, socioeconomic status, factors related to trauma or fracture, alcohol, tobacco, detection of depression scale, and financial compensation. A clinical and radiological follow-up took place at 6 weeks, 3 months, 6 months, and 1 year. The main functional measurement tool is the Mayo Elbow Performance Score (MEPS) and the Disabilities of the Arm, Shoulder and Hand (DASH). 123 patients were included in the study. 114 patients required nonsurgical management. 102 patients completed the 1-year follow-up for the main outcome (89 for the DASH score). Two patients required an unplanned surgery and were excluded from analyses. At 1 year, the average MEPS was 96.5 (range, 65–100) and 81% of subjects had an excellent result (MEPS ≥90). The most constant factor to predict an unsatisfactory functional outcome (MEPS <90 or DASH >17) is the presence of depressive symptoms at the initial time of the study (P = 0.03 and P = 0.0009, respectively). This factor is present throughout the follow-up. Other observed factors include a higher socioeconomic status (P = 0.009), the presence of financial compensation (P = 0.027), and a high-velocity trauma (P = 0.04). The severity of the fracture, advanced age, female sex, and the nature of the treatment does not influence the result at 1 year. No factor has been associated with a reduction in range of motion. Most of the radial head fractures heal successfully. We identified for the first time, with a valid tool, the presence of depressive symptoms at the time of the fracture as a significant factor for an unsatisfactory functional result. Early detection is simple and fast and would allow patients at risk to adopt complementary strategies to optimize the result

In reverse shoulder arthroplasty (RSA), a high complication rate is noted in the international literature (24.7%), and limited local literature is available. The complications in our developing health system, with high HIV, tuberculosis and metabolic syndrome prevalence may be different from that in developed health systems where the literature largely emanates from. The aim of this study is to describe the complications and complication rate following RSA in a South African cohort. An analytical, cross-sectional study was done where all patients’ who received RSA over an 11 year period at a tertiary hospital were evaluated. One-hundred-and-twenty-six primary RSA patients met the inclusion criteria and a detailed retrospective evaluation of their demographics, clinical variables and complication associated with their shoulder arthroplasty were assessed. All fracture, revision and tumour resection arthroplasties were excluded, and a minimum of 6 months follow up was required. A primary RSA complication rate of 19.0% (24/126) was noted, with the most complications occurring after 90 days at 54.2% (13/24). Instability was the predominant delayed complication at 61.5% (8/13) and sepsis being the most common in the early days at 45.5% (5/11). Haematoma formation, hardware failure and axillary nerve injury were also noted at 4.2% each (1/24). Keeping in mind the immense difference in socioeconomical status and patient demographics in a third world country the RSA complication rate in this study correlates with the known international consensus. This also proves that RSA is still a suitable option for rotator cuff arthropathy and glenohumeral osteoarthritis even in an economically constrained environment like South Africa

Worldwide, most spine imaging is either “inappropriate” or “probably inappropriate”. The Choosing Wisely recommendation is “Do not perform imaging for lower back pain unless red flags are present.” There is currently no detailed breakdown of lower back pain diagnostic imaging performed in New Brunswick (NB) to inform future directions. A registry of spine imaging performed in NB from 2011-2019 inclusive (n=410,000) was transferred to the secure platform of the NB Institute for Data, Training and Research (NB-IRDT). The pseudonymized data included linkable institute identifiers derived from an obfuscated Medicare number, as well as information on type of imaging, location of imaging, and date of imaging. The transferred data did not include the radiology report or the test requisition. We included all lumbar, thoracic, and complete spine images. We excluded imaging related to the cervical spine, surgical or other procedures, out-of-province patients and imaging of patients under 19 years. We verified categories of X-ray, Computed Tomography (CT), and Magnetic Resonance Imaging (MRI). Red flags were identified by ICD-10 code-related criteria set out by the Canadian Institute for Health Information. We derived annual age- and sex-standardized rates of spine imaging per 100,000 population and examined regional variations in these rates in NB's two Regional Health Authorities (RHA-A and RHA-B). Age- and sex-standardized rates were derived for individuals with/without red flag conditions and by type of imaging. Healthcare utilization trends were reflected in hospital admissions and physician visits 2 years pre- and post-imaging. Rurality and socioeconomic status were derived using patients’ residences and income quintiles, respectively. Overall spine imaging rates in NB decreased between 2012 and 2019 by about 20% to 7,885 images per 100,000 people per year. This value may be higher than the Canadian average. Females had 23% higher average imaging rate than males. RHA-A had a 45% higher imaging rate than RHA-B. Imaging for red flag conditions accounted for about 20% of all imaging. X-rays imaging accounted for 67% and 75% of all imaging for RHA-A and RHA-B respectively. The proportions were 20% and 8% for CT and 13% and 17% for MRI. Two-year hospitalization rates and rates of physician visits were higher post-imaging. Females had higher age-standardized hospitalization and physician-visit rates, but the magnitude of increase was higher for males. Individuals with red flag conditions were associated with increased physician visits, regardless of the actual reason for the visit. Imaging rates were higher for rural than urban patients by about 26%. Individuals in the lowest income quintiles had higher imaging rates than those in the highest income quintiles. Physicians in RHA-A consistently ordered more images than their counterparts at RHA-B. We linked spine imaging data with population demographic data to look for variations in lumbar spine imaging patterns. In NB, as in other jurisdictions, imaging tests of the spine are occurring in large numbers. We determined that patterns of imaging far exceed the numbers expected for ‘red flag’ situations. Our findings will inform a focused approach in groups of interest. Implementing high value care recommendations pre-imaging ought to replace low-value routine imaging

Introduction. It is thought that socioeconomic status and cultural upbringing influence the patient based outcomes of total joint arthroplasty. Previous studies have shown that patients in a lower socioeconomic class had surgery at an earlier age, increased comorbidities, increased severity of symptoms at presentation, and less satisfaction with the outcome. The purpose of this study was to compare the 1) reasons for undergoing total joint replacement and 2) satisfaction with the outcome among patients in different cultures and socioeconomic categories. We hypothesized that the overall reasons for undergoing surgery would be similar among all groups. Method. Patients undergoing total hip or knee arthroplasty were divided into groups based on their country of residence and socioeconomic status. The patients were asked to rank their reasons for undergoing surgery preoperatively from 1 to 4 according to importance. They were also asked to state how much relief of pain or improvement in function they expected to obtain. They were then asked to complete a questionnaire assessing their satisfaction with surgery 6 months post-operatively. These results were then compared across the three groups. Results. Thirty Nepalese patients and 10 American patients who received total hip or knee arthroplasty as part of a charitable outreach program were compared with 20 age and sex matched American patients who electively underwent total hip or knee arthroplasty. In both the Nepalese and outreach American patients, pain relief followed by improvement in performing everyday actions were listed as the most important reasons for undergoing surgery. The control group of American patients who sought surgery electively listed pain relief followed by improvement in performing individual activities as the main reasons for undergoing surgery. As compared to the other groups, the elective patients ranked athletic improvement higher as a reason for undergoing surgery. A review of the post-operative questionnaires completed by the Nepalese and American outreach patients showed that all were satisfied with the outcome of surgery and reported improvement in pain and the ability to perform individual as well as everyday activities. The postoperative questionnaires completed by the elective American patients showed satisfaction with the surgery, however, they reported less improvement in all functional categories. Conclusion. We found that, despite socioeconomic status, the reasons for undergoing total joint arthroplasty were similar among all groups. Pain relief was the most important reason for having surgery. There was a tendency for elective patients to rank participation in athletic activities higher than those in the lower socioeconomic groups. All patients were satisfied with their outcomes. However, the degree of subjective improvement among elective patients was less than that in lower socioeconomic groups. This may be due to the fact that, due to their lack of access to care, patients in lower socioeconomic groups had more severe disease prior to surgery

Distal radius fractures are common, yet the long-term functional outcome of these patients is unknown. This study investigated the long-term functional outcomes after distal radius fracture (DRF) in adult patients 16–23 years following injury. Secondary aims were to establish morbidity, mortality and function related to pattern of injury and patient demographics. Methods. 622 consented adult patients with a DRF were enrolled in the study. Prospective data was recorded; patient age, mechanism of injury and fracture pattern. Patients were assessed 16–23 years post-injury. 275 patients were deceased. 194 patients were able to complete a Quick Dash (QD) validated upper limb pain and function Patient-Reported Outcome Measure (PROM). Five patients declined follow-up. Socioeconomic status was assessed using the Scottish Index of Multiple Deprivation (SIMD) 2009. Results. The mean age at injury was 41 years for men and 64 for women in the initial cohort. 146 women and 48 men completed final follow-up. The mean age at QD assessment was 57 years for men and 76 for women; mean and median SIMD deciles were 6.7 and 7, respectively, for both genders. The mean QD score was 10.35 for all patients, with no significant gender difference (p=0.63). 85.6% (n=166) reported no or at most, mild limitation. High socioeconomic status, absence of other injuries at DRF and age under 85 years old at follow-up was associated with better long-term function. Early function and pain predicted long-term function; comminution pattern, treatment modality as chosen by surgeon, and early complications did not. Mortality data was analysed for the deceased (n=275). The mean patient survival from DRF to death was 11 years 5 months, with no significant gender difference (p=0.43); survival was predicted by age at injury, post-treatment dorsal angulation and early function. Respiratory, cardiovascular causes and malignancy were the three most common primary causes of death

Rotator cuff repair (RCR) can be performed open or arthroscopically, with a recent dramatic increase in the latter. Despite controversy about the preferred technique, there has been an increase in the number of repairs performed arthroscopically. The purpose of this study was, therefore, to compare revision rates following open and arthroscopic RCR repair. Adult patients undergoing first-time, primary rotator cuff repair in Ontario, Canada (April 2003-March 2014) were identified using physician billing and hospital databases. Patients were followed for a minimum of two and up to 13 years for the primary outcome, revision rotator cuff repair, and secondary outcome, surgical site infection. The intervention considered was open versus arthroscopic technique. Patient factors (age, gender, residence, socioeconomic status, medical comorbidities) and provider factors (surgical volume, hospital setting, worked night before, year of surgery) were recorded. Standardized mean differences were used for covariate comparison. A Cox Proportional Hazards model was used to compare RCR survivorship between the two groups after adjustment for patient and provider factors, generating hazard ratios with 95% confidence intervals (HR, 95% CIs). Censoring occurred on the first of the primary outcome, death, shoulder arthroplasty or arthrodesis, or the end of the follow-up period (March 2016). A total of 37,255 patients were included. The overall revision RCR rate was 2.9% (1,096 patients) with a median time to revision of 23 months (IQR 12–52). Revision repair was more common in the arthroscopic group in comparison to the open group (3.2% vs 2.6%, NNT 166.7, p=0.004), with an adjusted HR of 0.72 (0.63–0.83 95% CI, p < 0 .0001). The surgical site infection rate was significantly higher in the open group compared with the arthroscopic group (0.5% vs 0.2%, NNT 333.3, p < 0 .001). Patient and provider covariates had no statistically significant effect on revision rates, aside from increasing age (per 10 year increase, HR 0.85, 0.81–0.90 95% CI, p < 0 .0001). Revision rotator cuff repair is approximately 30% more common in patients undergoing arthroscopic repair, in comparison to open repair, after adjustment. Surgical site infection is uncommon regardless of surgical technique, however, it is slightly more common following open repair. In the setting of an economic healthcare crisis, trends of increasing arthroscopic RCR may demand scrutiny, as the technique is associated with higher revision rates and higher costs

Ten RCTs published between 2000 and 2013 support treating distal radius buckle fractures and other low-risk distal radius fractures with a removable splint and with no orthopaedic follow-up. Application of this evidence has been shown to be variable and suboptimal resulting in unnecessary costs to a strained healthcare system. The Canadian evidence on this topic has been generated by subspecialist physicians working in paediatric hospitals. It is unclear what factors affect the dissemination of this information. We investigated the association of hospital type and physician type with the application of best-evidence treatment for low-risk distal radius fractures in children with the goal of improving our understanding of evidence diffusion in Ontario for this common injury. We performed a retrospective population-based cohort study using linked health care administrative data. We identified all children aged 2–14 treated in Ontario emergency departments from 2003–2015 with distal radius fractures with no reduction and no operation within a six week period. We excluded refractures and children with comorbidities. We evaluated the followup received – orthopaedic, general practitioner, or none. We examined the data for trends over time. Multivariable log binomial regression was used to quantify associations between hospital and physician type and best-evidence treatment. We adjusted for patient-related variables including age, sex, rural or urban location, and socioeconomic status. 70,801 fractures were analyzed. Best-evidence treatment was more likely to occur in a small (RR 1.86, 95%CI 1.72–2.01), paediatric (RR 1.16, 95%CI 1.07–1.26), or community (RR 1.13, 95%CI 1.06–1.20) hospital compared with treatment in a teaching hospital. Best-evidence treatment was more likely if initial management was by a paediatrician with additional emergency medicine training (RR 1.73, 95%CI 1.56–1.92) or paediatrician (RR 1.22, 95%CI 1.11–1.34). Paediatric and teaching hospitals have improved their use of best-evidence over time while other hospital types have stagnated or deteriorated. Paediatricians, paediatricians with additional emergency medicine training, and emergency medicine residency trained physicians have improved their use of best-evidence over time, while other physician types have stagnated or deteriorated. Overall, only 20% of patients received best-evidence treatment and 70% had orthopaedic follow-up. Significant over-utilization of resources for low-risk distal radius fractures continues decades after the first randomized trials showed it to be unnecessary. Physician type and hospital rurality are most strongly associated with best-evidence treatment. Physician types involved in generating, presenting, and publishing best-evidence for this fracture type are successfully implementing it, while others have failed to change their practices. Rural hospitals are excellent resource stewards by necessity, but are deteriorating over time. Our results strongly indicate the need for targeted implementation strategies to explicitly apply clinical evidence in clinical practice Canada-wide, with the goal of providing more cost-effective care for common children's fractures

This aim of this study was to identify common factors in patients with the shortest length of hospital stay following total hip arthroplasty (THA). This would then allow a means of targeting suitable patients to reduce their length of stay. This was a retrospective cohort study of all patients undergoing primary THA at our institution between September 2013 and August 2014. Demographic data were collected from the patient record. The cohort was divided into those discharged to home within two days of operation and the rest of the THA population. The demographics (age, gender, ASA grade, body mass index (BMI), primary diagnosis, socioeconomic status (Scottish Index of Multiple Deprivation, SIMD and SIMD health domain) were compared between groups. In addition for the early discharge group information on comorbidities, family support at home and independent transport were collected. The study cohort was 1292 patients. 119 patients were discharged home on the first post-operative day. Those discharged earlier were on average younger (p<0.0001), more likely to be male (p<0.0001) and had a lower ASA grade (p<0.00001). Other demographics did not differ between groups. Patients who were discharged early also appeared to have few comorbidities (Diabetes 5.9%, Cardiac disease 7.6%, Respiratory disease 9%), high levels of family support at home (95%) and high levels of independent transport arrangements (97%). Factors associated with those patients with the shortest lengths of stay were identified. Such factors could be used to target patients who are suitable for streamlined recovery programmes aimed at early discharge after THA and assist with service planning

Introduction. Alternative payment models, such as bundled payments, aim to control rising costs for total knee (TKA) and total hip arthroplasty (THA). Without risk adjustment for patients who may utilize more resources, concerns exist about patient selection and access to care. The purpose of this study was to determine whether lower socioeconomic status (SES) was associated with increased resource utilization following TKA and THA. Methods. Using the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) database, we reviewed a consecutive series of 4,168 primary TKA and THA patients over a 3-year period. We defined lowest SES based upon the median household income of the patient's ZIP code. An a prioripower analysis was performed to determine the appropriate sample size. Demographics, medical comorbidities, length of stay, discharge destination, and readmission rates were compared between patients of lowest SES and higher SES. Results. Patients in the lowest SES group had a longer hospital length of stay (2.79 vs. 2.22 days, p<0.001), were more likely to be discharged to a rehabilitation facility (27% vs. 18%, p<0.001), and be readmitted to the hospital within 90 days (11% vs. 8%, p=0.002) than the higher SES group. In the multivariate analysis, lowest SES was found to be an independent risk factor for 90-day readmission rate (OR 1.50, 95% CI 1.15–1.96, p=0.003), extended hospital LOS 4 days or greater (OR 2.34, 95% CI 1.78–3.07, p<0.001), and discharge to a rehabilitation facility (OR 1.64, 95% CI 1.34–2.01, p<0.001). Both age greater than 75 years and obesity were also independent risk factors for all three outcome measures. Conclusion. Patients in the lowest SES group utilize more resources in the 90-day postoperative period. Therefore, risk adjustment models, including SES, may be necessary to fairly compensate hospitals and surgeons and to avoid potential problems with access to joint replacement care

Septic arthritis is a rare form of infection in the healthy adult population, especially adults who have never been submitted to any articular procedure. Our objective is to describe a rare case of an infectious arthritis of a hip caused by bone abscess in a previously healthy patient with few risk factors. This is the case of a 40 year-old female, who had a history of heavy smoking and low socioeconomic status. She was examined complaining with pain in the left hip and the x-ray showed a lytic image in the intracapsular femoral neck, but it was overlooked and the diagnosis of bone abscess was missed. She was to the hospital 3 weeks later with intense pain and a suppurative and swollen right thigh. Blood analyses were compatible with infection (elevated white-blood cells and C-reactive protein). Pelvic CT scan showed a lytic image in the intracapsular femoral neck with pus inside the hip. It also showed a huge abscess and infiltration of the tissues surrounding. She was then submitted to multiple surgeries in order to drain the abscess and articular cleaning. A S. aureus MSSA was isolated and an adequate antibiotic was instituted. Although this measures, there was only partial clinical and analytical success. We eventually ended-up by resecting the femoral head, which had no viability, as shown in an MRI, and was behaving as a sequestrum, justifying the impossibility in controlling the infection. The femoral head was replaced by a temporary cement-spacer impregnated with vancomycin, and the patient maintained adequate antibiotic therapy until normalization of the infection parameters. She now has no signs of infection, and is waiting to be submitted to a total hip replacement. This is a rare case of a septic arthritis with an uncommon onset in a healthy woman who had never been submitted to a hip procedure and had no local risk factors for the development of such pathology. In the research we did, we found no other case similar to this, in which the arthritis started as an intracapsular bone abscess with hematogenous origin. Reporting this case, we would also like to emphasize that, although its rarity, it is extremely important to always exclude septic arthritis in cases of joint pain, in order to prevent catastrophic consequences

Developmental dysplasia of the hip (DDH) refers to a spectrum of anatomical abnormalities. Despite various screening programs, delayed diagnosis still occurs. Delayed cases are more difficult to treat and can have poorer outcomes. Rural address, low socioeconomic status, and ethnicity have recently been associated with late presentation. The objectives of this study were to examine the incidence of DDH, as well as factors associated with delayed presentation in Saskatchewan. Retrospective review of paediatric orthopaedic records from the tertiary referral centre in Saskatchewan was completed from 2008–2014. Variables collected included age at presentation, sex, birth order, birth presentation, birth complications, laterality, family history of DDH, postal code and treatment. Socioeconomic and geographic indicators were determined from postal code using the 2011 National Household Survey. Population level variables included income, ethnic origin, distance from referral centre and education. Associations were examined with bivariate and multivariate analysis. There were 108 new presentations of DDH; 34 cases presented after age 3 months. Demographic data showed 83.3% of cases were female, 48.1% involved the left hip, 17.2% had a positive family history, 57.1% were first born, and 27.9% were breech. An estimated 5.6% of patients were Aboriginal. The mean age at presentation was 199.7 days. 48% of cases lived in the same city as the referral center. Late presenting cases lived on average 46.19 km farther from the referral centre and had a lower mean population, percent of adults with post-secondary education and income. However, none of these were statistically significant. No significant associations were found within the demographic data. Overall incidence of DDH was not estimated due to few cases from southern areas of the province presenting to the tertiary referral center. The estimated incidence of DDH in the Aboriginal population from our sample was lower than previously reported in the literature. This association may be related to earlier swaddling practices, rather than Aboriginal ethnicity. There was a trend toward lower socioeconomic indicators and an increased distance from the referral centre in cases of late presentation, in keeping with recent literature exploring these factors. This suggests there may be deficits in the current selective screening protocols in North America. The study is limited by the retrospective nature of the research and the population level data obtained for certain variables. Future research to collect prospective individual level data may help elucidate important associations. Also, identifying any additional cases would increase the power to detect significant associations with late presentation, and allow an accurate estimate of overall incidence

Introduction. Intimate partner violence (IPV) is a pattern of coercive behaviours that include repeated physical, sexual and emotional abuse. Musculoskeletal injuries are common symptoms of IPV. We aimed to determine the proportion of female patients, attending orthopaedic fracture clinics, that have experienced IPV defined as physical, sexual, or emotional abuse within the past 12 months. Methods. We completed a cross-sectional study of 282 injured women attending two Level I trauma centres in Canada. Female patients presenting to the orthopaedic fracture clinics completed two validated self-reported written questionnaires; the Woman Abuse Screening Tool (WAST) and the Partner Violence Screen (PVS) to determine the prevalence of IPV. The questionnaire also contained questions that pertain to participant demographics, fracture characteristics, and experiences with health care utilisation. Results. The overall prevalence of IPV (emotional, physical, and sexual abuse) within the last 12 months was 32% (95% Confidence Interval 26.4% to 37.2%) amongst the 282 respondents. One in 12 injured women disclosed a history of physical abuse (24/282, 8.5%) in the past year. Seven women (2.5%) indicated the cause for their current visit was directly related to physical abuse, and 5 of these cases included fractures. We did not identify any significant trends in ethnicity, socioeconomic status, or injury patterns as markers of domestic abuse. Of 24 women with physical injuries, only 4 had been asked about IPV by a physician and none of the physicians were their treating orthopaedic surgeons. Conclusion. Our study confirms a high prevalence of IPV among female patients with injuries attending orthopaedic surgical clinics in Ontario. Similar to previous research, our study found that women of all ages, ethnicities, social economic status, and injury patterns may experience IPV. Surgeons should consider screening all injured women for domestic violence in their clinics

Aims

Deprivation underpins many societal and health inequalities. COVID-19 has exacerbated these disparities, with access to planned care falling greatest in the most deprived areas of the UK during 2020.
