Aims. The aim of this study was to examine whether socioeconomic status (SES) is associated with a higher risk of infections following total hip arthroplasty (THA) at 30 and 90 days. Methods. We obtained individual-based information on SES markers (cohabitation, education, income, and savings) on 103,901 THA patients from Danish health registries between 1 January 1995 and 31 December 2017. The primary outcome measure was any hospital-treated infection (i.e. all infections). The secondary outcomes were further specified to specific hospital-treated infections (pneumonia, urinary tract infection, and periprosthetic joint infection). The primary timepoint was within 90 days. In addition, the outcomes were further evaluated within 30 days. We calculated the cumulative incidence, and used the pseudo-observation method and generalized linear regression to estimate adjusted risk ratios (RRs) with 95% confidence intervals (CIs) for each marker. Results. The cumulative incidence of any infection at 90 days was highest in patients who lived alone (1.5% (95% CI 1.3 to 1.6)) versus cohabitant (0.7% (95% CI 0.7 to 0.8)), had the lowest educational achievement (1.1% (95% CI 1.0 to 1.2)) versus highest (0.7% (95% CI 0.5 to 0.8)), had the lowest income (1.6% (95% CI 1.5 to 1.70)) versus highest (0.4% (95% CI 0.3 to 0.5)), or had lowest savings (1.3% (95% CI 1.2 to 1.4)) versus highest (0.7% (95% CI 0.6 to 0.8)). Within 90 days, the RRs for any infection were 1.3 (95% CI 1.2 to 1.4) for patients living alone versus cohabiting, 1.2 (95% CI 1.0 to 1.3) for low education achievement versus high, 1.7 (95% CI 1.4 to 2.1) for low income versus high income, and 1.5 (95% CI 1.4 to 1.8) for low savings versus high savings. The same trends were also seen for any infections within the first 30 days. Conclusion. Our study provides evidence that socioeconomic inequality adversely influences the risk of infection after THA, thus contributing to healthcare disparities and inequalities. We found that living alone, low educational achievement, low income, or low savings were associated with higher risks of infections within the first 30 and 90 days after THA. Therefore, the development of targeted intervention strategies with the aim of increasing awareness of patients identified as being at greatest risk is needed to mitigate the impact of SES on the risk of infections following THA.

We assessed the effect of social deprivation upon the Oxford knee score (OKS), the Short-Form 12 (SF-12) and patient satisfaction after total knee replacement (TKR). An analysis of 966 patients undergoing primary TKR for symptomatic osteoarthritis (OA) was performed. Social deprivation was assessed using the Scottish Index of Multiple Deprivation. Those patients that were most deprived underwent surgery at an earlier age (p = 0.018), were more likely to be female (p = 0.046), to endure more comorbidities (p = 0.04) and to suffer worse pain and function according to the OKS (p < 0.001). In addition, deprivation was also associated with poor mental health (p = 0.002), which was assessed using the mental component (MCS) of the SF-12 score. Multivariable analysis was used to identify independent predictors of outcome at one year. Pre-operative OKS, SF-12 MCS, back pain, and four or more comorbidities were independent predictors of improvement in the OKS (all p < 0.001). Pre-operative OKS and improvement in the OKS were independent predictors of dissatisfaction (p = 0.003 and p < 0.001, respectively). Although improvement in the OKS and dissatisfaction after TKR were not significantly associated with social deprivation per se, factors more prevalent within the most deprived groups significantly diminished their improvement in OKS and increased their rate of dissatisfaction following TKR.

There is little known about how patient socioeconomic status impacts clinical outcomes in hip preservation surgery. The aim of this study was to evaluate the relationship between indices of multiple deprivation, funding provider (NHS Funded or Private Funded) and clinical outcomes following surgery for femoroacetabular impingement (FAI). The study analysed the data of 5590 patients recorded in the NAHR who underwent primary hip arthroscopic treatment for FAI between November 2013 and July 2023. Records were matched to the UK National index of multiple deprivation using the lower layer super output area. Using iHOT12 score, patient reported outcome measures were analysed at base line and 1 year following surgery. 2358 records were matched to LLSOA deciles. Between the lowest (most deprived) 3 deciles and the highest (least deprived) the average baseline iHOT12 score was 28.98 (n=366) and 35.33 (n=821). The proportion of patients receiving treatment through NHS funding compared to independent funding for the most deprived, 292 (90%) 37 (10%) respectively compared to the least deprived 515 (70%) and 244 (30%) respectively. At 1year, iHOT12 scores for each group were 51.64 (29.1 SD) compared to 61.5 (28.06 SD) respectively. The study demonstrates that patients from lower socioeconomic backgrounds had poorer baseline and one-year post-surgery iHOT12 scores compared to those from higher socioeconomic strata. Furthermore, a higher reliance on NHS funding was observed among the most deprived, while more affluent patients predominantly opted for private funding. These findings underscore the significant influence of socioeconomic status on both the quality of healthcare received and recovery outcomes in hip preservation surgery, calling attention to the need for more equitable healthcare solutions

This is the first study to use the English Indices of Multiple Deprivation 2007, the Government’s official measure of multiple deprivation, to analyse the effect of socioeconomic status on the incidence of fractures of the hip and their outcome and mortality. Our sample consisted of all patients admitted to hospital with a fracture of the hip (n = 7511) in Nottingham between 1999 and 2009. The incidence was 1.3 times higher (p = 0.038) in the most deprived populations than in the least deprived; the most deprived suffered a fracture, on average, 1.1 years earlier (82.0 years versus 83.1 years, p < 0.001). The mortality rate proved to be significantly higher in the most deprived population (log-rank test, p = 0.033), who also had a higher number of comorbidities (p = 0.001). This study has shown an increase in the incidence of fracture of the hip in the most deprived population, but no association between socioeconomic status and mortality at 30 days. Preventative programmes aimed at reducing the risk of hip fracture should be targeted towards the more deprived if they are to make a substantial impact

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

This prospective study assessed the effect of social deprivation on the Oxford hip score at one year after total hip replacement. An analysis of 1312 patients undergoing 1359 primary total hip replacements for symptomatic osteoarthritis was performed over a 35-month period. Social deprivation was assessed using the Carstairs index. Those patients who were most deprived underwent surgery at an earlier age (p = 0.04), had more comorbidities (p = 0.02), increased severity of symptoms at presentation (p = 0.001), and were not as satisfied with their outcome (p = 0.03) compared with more affluent patients. There was a significant improvement in Oxford scores at 12 months relative to pre-operative scores for all socioeconomic categories (p < 0.001). Social deprivation was a significant independent predictor of mean improvement in Oxford scores at 12 months, after adjusting for confounding variables (p = 0.001). Deprivation was also associated with an increased risk of dislocation (odds ratio 5.3, p < 0.001) and mortality at 90 days (odds ratio 3.2, p = 0.02). Outcome, risk of dislocation and early mortality after a total hip replacement are affected by the socioeconomic status of the patient

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

The goal of the current study was to determine if SES affects PROMs in patients treated with THA. Specifically, we sought to determine any potential differences between low and high SES patients in pre-surgical PROMs, post-surgical PROMs, and PROM improvement after surgery while controlling for any potential confounding demographic factors.

Methods

Patients were selected from a clinical registry at an urban tertiary academic medical center. All patients undergoing primary THA between January 1, 2000 and April 1, 2016 were eligible for this study. During this period, patients were asked to complete the Harris Hip Score (HHS), Euro-QoL 5 Dimension (EQ-5D), 0–10 Numerical Rating Scale (NRS) Pain, 0–10 NRS Satisfaction (only given postoperatively), the Charnley Classifier, and the University of California Los Angeles (UCLA) Activity Score.

To determine SES, patients were matched by zip code to corresponding median household income as reported by the United States Census Bureau. Patients were then dichotomized into low and high SES groups using 2016 median household income of $57,617 USD as a cutoff point.

Statistical differences between low and high SES patients were determined for demographic factors, preoperative PROMs, postoperative PROMs, and PROM change. Non-parametric variables were tested with the Mann Whitney U test and categorical variables were tested with the Chi squared test.

Multivariate models were created to determine if SES group was independently predictive of achieving a minimal clinically important improvement (MCII) in PROMs (18.0 for HHS, −2.0 for NRS Pain, and 0.92 for UCLA). As potential confounders, we tested body mass index (BMI), preoperative health state from EQ-5D visual analog scale (EQ VAS), age at surgery, preoperative Charnley class, sex, and time between PROMs.

Aims. Total hip arthroplasty (THA) is one of the most successful surgical procedures. The objectives of this study were to define whether there is a correlation between socioeconomic status (SES) and surgical complications after elective primary unilateral THA, and investigate whether access to elective THA differs within SES groups. Methods. We conducted a retrospective, population-based cohort study involving 202 hospitals in Ontario, Canada, over a 17-year period. Patients were divided into income quintiles based on postal codes as a proxy for personal economic status. Multivariable logistic regression models were then used to primarily assess the relationship between SES and surgical complications within one year of index THA. Results. Of 111,359 patients who underwent elective primary THA, those in the lower SES groups had statistically significantly more comorbidities and statistically significantly more postoperative complications. While there was no increase in readmission rates within 90 days, there was a statistically significant difference in the primary and secondary outcomes including all revisions due (with a subset of deep wound infection and dislocation). Results showed that those in the higher SES groups had proportionally more cases performed than those in lower groups. Compared to the highest SES quintile, the lower groups had 61% of the number of hip arthroplasties performed. Conclusion. Patients in lower socioeconomic groups have more comorbidities, fewer absolute number of cases performed, have their procedures performed in lower-volume centres, and ultimately have higher rates of complications. This lack of access and higher rates of complications is a “double hit” to those in lower SES groups, and indicates that we should be concentrating efforts to improve access to surgeons and hospitals where arthroplasty is routinely performed in high numbers. Even in a universal healthcare system where there are no penalties for complications such as readmission, there seems to be an inequality in the access to THA.

Aims. It is unclear whether mortality outcomes differ for patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) surgery who are readmitted to the index hospital where their surgery was performed, or to another hospital. Methods. We analyzed linked hospital and death records for residents of New South Wales, Australia, aged ≥ 18 years who had an emergency readmission within 90 days following THA or TKA surgery between 2003 and 2022. Multivariable modelling was used to identify factors associated with non-index readmission and to evaluate associations of readmission destination (non-index vs index) with 90-day and one-year mortality. Results. Of 394,248 joint arthroplasty patients (THA = 149,456; TKA = 244,792), 9.5% (n = 37,431) were readmitted within 90 days, and 53.7% of these were admitted to a non-index hospital. Non-index readmission was more prevalent among patients who underwent surgery in private hospitals (60%). Patients who were readmitted for non-orthopaedic conditions (62.8%), were more likely to return to a non-index hospital compared to those readmitted for orthopaedic complications (39.5%). Factors associated with non-index readmission included older age, higher socioeconomic status, private health insurance, and residence in a rural or remote area. Non-index readmission was significantly associated with 90 day (adjusted odds ratio (aOR) 1.69; 95% confidence interval (CI) 1.39 to 2.05) and one-year mortality (aOR 1.31; 95% CI 1.16 to 1.47). Associations between non-index readmission and mortality were similar for patients readmitted with orthopaedic and non-orthopaedic complications (90-day mortality aOR 1.61; 95% CI 0.98 to 2.64, and aOR 1.67; 95% CI 1.35 to 2.06, respectively). Conclusion. Non-index readmission was associated with increased mortality, irrespective of whether the readmission was for orthopaedic complications or other conditions.

Aims. The aim of this study was to perform the first population-based description of the epidemiological and health economic burden of fracture-related infection (FRI). Methods. This is a retrospective cohort study of operatively managed orthopaedic trauma patients from 1 January 2007 to 31 December 2016, performed in Queensland, Australia. Record linkage was used to develop a person-centric, population-based dataset incorporating routinely collected administrative, clinical, and health economic information. The FRI group consisted of patients with International Classification of Disease 10th Revision diagnosis codes for deep infection associated with an implanted device within two years following surgery, while all others were deemed not infected. Demographic and clinical variables, as well as healthcare utilization costs, were compared. Results. There were 111,402 patients operatively managed for orthopaedic trauma, with 2,775 of these (2.5%) complicated by FRI. The development of FRI had a statistically significant association with older age, male sex, residing in rural/remote areas, Aboriginal or Torres Strait Islander background, lower socioeconomic status, road traffic accident, work-related injuries, open fractures, anatomical region (lower limb, spine, pelvis), high injury severity, requiring soft-tissue coverage, and medical comorbidities (univariate analysis). Patients with FRI had an eight-times longer median inpatient length of stay (24 days vs 3 days), and a 2.8-times higher mean estimated inpatient hospitalization cost (AU$56,565 vs AU$19,773) compared with uninfected patients. The total estimated inpatient cost of the FRI cohort to the healthcare system was AU$156.9 million over the ten-year period. Conclusion. The results of this study advocate for improvements in trauma care and infection management, address social determinants of health, and highlight the upside potential to improve prevention and treatment strategies.

Aims. The aims of this study were to assess quality of life after hip fractures, to characterize respondents to patient-reported outcome measures (PROMs), and to describe the recovery trajectory of hip fracture patients. Methods. Data on 35,206 hip fractures (2014 to 2018; 67.2% female) in the Norwegian Hip Fracture Register were linked to data from the Norwegian Patient Registry and Statistics Norway. PROMs data were collected using the EuroQol five-dimension three-level questionnaire (EQ-5D-3L) scoring instrument and living patients were invited to respond at four, 12, and 36 months post fracture. Multiple imputation procedures were performed as a model to substitute missing PROM data. Differences in response rates between categories of covariates were analyzed using chi-squared test statistics. The association between patient and socioeconomic characteristics and the reported EQ-5D-3L scores was analyzed using linear regression. Results. The median age was 83 years (interquartile range 76 to 90), and 3,561 (10%) lived in a healthcare facility. Observed mean pre-fracture EQ-5D-3L index score was 0.81 (95% confidence interval 0.803 to 0.810), which decreased to 0.66 at four months, to 0.70 at 12 months, and to 0.73 at 36 months. In the imputed datasets, the reduction from pre-fracture was similar (0.15 points) but an improvement up to 36 months was modest (0.01 to 0.03 points). Patients with higher age, male sex, severe comorbidity, cognitive impairment, lower income, lower education, and those in residential care facilities had a lower proportion of respondents, and systematically reported a lower health-related quality of life (HRQoL). The response pattern of patients influenced scores significantly, and the highest scores are found in patients reporting scores at all observation times. Conclusion. Hip fracture leads to a persistent reduction in measured HRQoL, up to 36 months. The patients’ health and socioeconomic status were associated with the proportion of patients returning PROM data for analysis, and affected the results reported. Observed EQ-5D-3L scores are affected by attrition and selection bias mechanisms and motivate the use of statistical modelling for adjustment. Cite this article: Bone Joint J 2024;106-B(4):394–400

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

Aims. Social determinants of health (SDOHs) may contribute to the total cost of care (TCOC) for patients undergoing total knee arthroplasty (TKA). The aim of this study was to investigate the association between demographic data, health status, and SDOHs on 30-day length of stay (LOS) and TCOC after this procedure. Methods. Patients who underwent TKA between 1 January 2018 and 31 December 2019 were identified. A total of 234 patients with complete SDOH data were included. Data were drawn from the Chesapeake Regional Information System, the Centers for Disease Control social vulnerability index (SVI), the US Department of Agriculture, and institutional electronic medical records. The SVI identifies areas vulnerable to catastrophic events with four themed scores: socioeconomic status; household composition and disability; minority status and language; and housing and transportation. Food deserts were defined as neighbourhoods located one or ten miles from a grocery store in urban and rural areas, respectively. Multiple regression analyses were performed to determine associations with LOS and costs after controlling for various demographic parameters. Results. Divorced status was significantly associated with an increased LOS (p = 0.043). Comorbidities significantly associated with an increased LOS included chronic obstructive pulmonary disease/asthma and congestive heart failure (p = 0.043 and p = 0.001, respectively). Communities with a higher density of tobacco stores were significantly associated with an increased LOS (p = 0.017). Comorbidities significantly associated with an increased TCOC included chronic obstructive pulmonary disease (p = 0.004), dementia (p = 0.048), and heart failure (p = 0.007). Increased TCOCs were significantly associated with patients who lived in food deserts (p = 0.001) and in areas with an increased density of tobacco stores (p = 0.023). Conclusion. Divorced marital status was significantly associated with an increased LOS following TKA. Living in food deserts and in communities with more tobacco stores were significant risk factors for increased LOS and TCOC. Food access and ease of acquiring tobacco may both prove to be prognostic of outcome after TKA and an opportunity for intervention. Cite this article: Bone Joint J 2021;103-B(6 Supple A):113–118

Introduction. We used patient reported outcome measures (PROMS) to evaluate qualitative and societal outcomes of trauma. Methods. We collected PROMs data between Sept 2013 and March 2015 for 92 patients with injury severity score (ISS) greater than 9. We enquired regarding return to work, income and socioeconomic status, dignity and satisfaction and the EQ-5D questionnaire. Results. Return to work. Of patients working at admission 15/58(26%) anticipated returning to work within 14 days of discharge. Work plans at discharge did not correlate with ISS scores overall (r=−0.05, ns), or when stratified by working group. Increased physicality of work showed a trend towards poorer return to work outcomes (not significant in Spearman's rank analysis: r= 0.14, p= 0.32). Income and socioeconomic status: No significant difference was demonstrated between the comparative incomes of patients with the best and worst return to work outcomes (ANOVA n=61, t=0.63, ns). Lowest quartile earners (n=19) were more likely to complete the open questions (79%) than higher income patients (62%). Dignity and satisfaction: Prominent positive themes were: care, staff, professionalism, and communication. Prominent negative themes were: food, ward response time, and communication. %). Patients ‘mostly’ or ‘always’ satisfied with their care did not have significantly different incomes (ANOVA, t=0.13, ns). EQ-5D: Self-rated health status correlated with perceived likelihood of return to work (r=0.25, p=0.0395). Correlation was demonstrated between EQ-5D scores and perceived dignity preservation (r=0.38, p=0.0004), and overall satisfaction (r=0.46, p< 0.0001). There was no correlation between EQ-5D and ISS score. Conclusion. EQ5D correlated with work plans, dignity, and satisfaction. Planned return to work did not correlate with ISS score or socioeconomic status. Unlike previous studies we demonstrated that lower socioeconomic groups have best engagement with PROMS. This study highlighted the value of qualitative PROMS analysis in leading patient-driven improvements in trauma care

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

Abstract. Background. There is a trend towards minimising length of stay (LOS) after total knee arthroplasty (TKA), as longer LOS is associated with poorer outcomes and higher costs. Patient factors known to influence LOS after TKA include age and ASA grade. Evidence regarding body mass index (BMI) in particular is conflicting. Some studies find that increased BMI predicts greater LOS, while others find no such relationship. Previous studies have generally not examined socioeconomic status, which may be a confounder. They have generally been conducted outside the UK, and prior to the Covid-19 pandemic. Methods. We conducted a retrospective cohort study of 1031 primary TKAs performed 01-04-2021 to 31-12-2021, after resumption of elective surgery in our centre. A multivariate regression analysis was performed using a Poisson model over pre-operative variables (BMI, age, gender, ASA grade, index of multiple deprivation, and living arrangement) and peri-operative variables (AM/PM operation, operation side, duration, and day of the week). Results. Mean LOS was 2.6 days. BMI had no effect on LOS (p > 0.05). Longer LOS was experienced by patients of greater age (p < 0.001), increased ASA grade (p < 0.001), living alone (p < 0.01), PM start time (p < 0.001), and longer operation duration (p < 0.01). Male patients had shorter LOS (p < 0.001). Index of multiple deprivation had no effect (p > 0.05). Conclusion. BMI had no effect on LOS after TKA. Being female and living alone are significant risk factors which should be taken in to account in pre-operative planning

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

Aims. Cephalomedullary nails (CMNs) are commonly used for the treatment of intertrochanteric hip fractures. Total hip arthroplasty (THA) may be used as a salvage procedure when fixation fails in these patients. The aim of this study was to analyze the complications of THA following failed intertrochanteric hip fracture fixation using a CMN. Patients and Methods. Patients who underwent THA were identified from the 5% subset of Medicare Parts A/B between 2002 and 2015. A subgroup involving those with an intertrochanteric fracture that was treated using a CMN during the previous five years was identified and compared with the remaining patients who underwent THA. The length of stay (LOS) was compared using both univariate and multivariate analysis. The incidence of infection, dislocation, revision, and re-admission was compared between the two groups, using multivariate analysis adjusted for demographic, hospital, and clinical factors. Results. The Medicare data yielded 56 522 patients who underwent primary THA, of whom 369 had previously been treated with a CMN. The percentage of THAs that were undertaken between 2002 and 2005 in patients who had previously been treated with a CMN (0.346%) more than doubled between 2012 and 2015 (0.781%). The CMN group tended to be older and female, and to have a higher Charlson Comorbidity Index and lower socioeconomic status. The mean LOS was 1.5 days longer (5.3 vs 3.8) in the CMN group (p < 0.0001). The incidence of complications was significantly higher in the CMN group compared with the non-CMN group: infection (6.2% vs 2.6%), dislocation (8.1% vs 4.5%), revision (8.4% vs 4.3%), revision for infection (1.1% vs 0.37%), and revision for dislocation (2.2% vs 0.6%). Conclusion. The incidence of conversion to THA following failed intertrochanteric hip fracture fixation using a CMN continues to increase. This occurs in elderly patients with increased comorbidities. There is a significantly increased risk of infection, dislocation, and LOS in these patients. Patients with failed intertrochanteric hip fracture fixation using a CMN who require THA should be made aware of the increased risk of complications, and steps need to be taken to reduce this risk.

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

Introduction. Social determinants of health (SDOH) may contribute markedly to the total cost of care (COC) for patients undergoing elective total knee arthroplasty (TKA). This study investigated the association between demographics, health status, and SDOH on lengths of stay (LOS) and 30-day COC. Methods. Patients who underwent TKA between January 2018 and December 2019 were identified. Those who had complete SDOH data were utilized, leaving 234 patients. Data elements were drawn from the Chesapeake Regional Information System, the Center for Disease Control social vulnerability index (SVI), the Food Access Research Atlas (FARA). The SVI identifies areas vulnerable to catastrophic events, with 4 themed scores including: (1) socioeconomic status; (2) household composition and disability; (3) minority status and language; and (4) housing and transportation. Food deserts were defined as neighborhoods located 1 or 10 miles from a grocery store in urban and rural areas, respectively. Multiple regression analyses were performed to determine an association with LOS and cost, after controlling for demographics. Results. Increased 30-day COC associated with SVI theme 3, (3.074 days; p=0.001) and patients who lived in a food desert ($53,205; p=0.001), as well as those who had anemia ($16,112; P = 0.038), chronic obstructive pulmonary disease ($32,570, P = 0.001), congestive heart failure ($30,927, P = 0.003), and dementia ($33,456, P = 0.008). Longer hospital lengths of stay were associated with SVI theme 3. In addition, patients who had anemia and congestive heart failure were at risk for longer hospital lengths of stay (P < 0.001, P = 0.001, respectively). Conclusion. Higher SVI theme 3 scores and living in food deserts were risk factors for increased LOS and costs, respectively. Identifying social factors including a patient's transportation options, living situation and access to healthy foods may prove to be both prognostic of outcomes and an opportunity for intervention

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

Introduction. Cephalomedullary nails (CMN) are commonly used for the treatment of intertrochanteric (IT) hip fractures. Total hip arthroplasty (THA) is commonly used as a salvage procedure for failed IT hip fractures that progress to post-traumatic arthritis. This study analyzed the complications of THA following treatment of failed IT hip fractures with cephalomedullary nails. Methods. Patients who had a primary THA were identified from the 5% subset of Medicare Parts A/B from 2002–2015. A subgroup with previous CMN for IT hip fracture within the previous 5 years was identified and compared to the remaining THA patients without prior CMN. Length of stay (LOS) was compared using both univariate and multivariate analysis. Infection, dislocation, revision, and readmission were compared between those with and without prior CMN, using multivariate analysis (adjusted for demographic, hospital, and clinical factors). Results. 5% subset of the Medicare data yielded 56,522 primary THA, with 369 treated with prior CMN. The percentage of primary THA from 2002–2005 with prior cephalomedullary nails (0.346%) more than doubled in 2012–2015 (0.781%). The prior CMN group tended to be older, female, higher CCI, and lower socioeconomic status. Mean LOS was 1.5 days longer (5.3 vs 3.8) in the prior CMN group (p<0.0001). The percentage of postoperative complications was significantly higher in the prior CMN group compared to non-CMN cohort: infection (6.2% vs 2.6%), dislocation (8.1% vs 4.5%), revision (8.4% vs 4.3%), revision for infection (1.1% vs 0.37%), and revision for dislocation (2.2% vs 0.6%). Discussion. Conversion from failed IT hip fractures with cephalomedullary nails to total hip arthroplasty continues to increase. These cases occur in elderly patients with increased comorbidities. There is a significantly increased risk of infection, dislocation and LOS in the CMN group. Patients with failed IT hip fractures undergoing THA should be made aware of the increased complication risk and further steps need to be undertaken to diminish the elevated risk

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

Limb reconstruction requires high levels of patient compliance and impacts heavily on social circumstances. The epidemiology and socioeconomic description of trauma patients has been well documented, however no study has assessed the epidemiology of limb reconstruction patients. The aim of this project is to describe patients attending Limb Reconstruction Services (LRS) in order to highlight and address the social implications of their care. All LRS cases under a single surgeon in a district general hospital were included from 2010 – 2016. Demographics, ASA grade, smoking status, mental health status and employment status were collated. Postcode was converted into an Index of Multiple Deprivation score using GeoConvert® software. Patient socioeconomic status was then ranked into national deprivation score quintiles (quintile 1 is most affluent, quintile 5 is most deprived). Deprivation scores were adjusted by census data and analysed with Student's T-test. The distance from the patient's residence to the hospital was generated through AA route planner®. Patient attendance at clinic and elective or emergency admissions was also assessed. Patient outcomes were not part of this research. There were 53 patients, of which 66% (n=35) were male, with a mean age of 45 years (range 21–89 years). Most patients were smokers (55%, n=29), 83% (n=42) were ASA 1 or 2 (there were no ASA 4 patients). The majority of indications were for acute trauma (49%), chronic complications of trauma (32%), congenital deformity (15%) and salvage fusion (4%). Mental health issues affected 23% (n=12) of cases and 57% of working-aged patients were unemployed. Mental health patients had a higher rate of trauma as an indication than the rest of the cohort (93% vs. 76%). Deprivation quintiles identified that LRS patients were more deprived (63% in quintiles 4 and 5 vs. 12% of 1 and 2), but this failed to reach statistical significance (p=0.9359). The mean distance from residence to hospital was 12 miles (range 0.35–105 miles, median 7 miles). The patients derived from a large region made up of 12 local authorities. There was a mean of 17 individual LRS clinic attendances per patient (range: 3–42). Cumulative distance travelled for each patient during LRS treatment was a mean of 495 miles (range 28 – 2008 miles). The total distance travelled for all 53 patients was over 26,000 miles. The results largely mirror the findings of trauma demographic and socioeconomic epidemiology, due to the majority of LRS indications being post-traumatic in this series. The high rates of unemployment and mental health problems may be a risk factor for requiring LRS management, or may be a product of the treatment. Clinicians may want to consider a social care strategy alongside their surgical strategy and fully utilise their broader MDT to address the social inequalities in these patients. This strategy should include a mental health assessment, smoking cessation therapy, sign-posted support for employment circumstances and a plan for travel to the hospital. The utilisation and cost of ambulance services was not possible with this methodology. Further work should prospectively assess the changes in housing circumstances, community healthcare needs and whether there was a return to employment and independent ambulation at the end of treatment

We report the largest series of periprosthetic fractures in the literature, describing the changing epidemiology and predictors of outcome. A retrospective search of prospectively compiled trauma and elective electronic databases identified 630 periprosthetic fractures presenting to the study centre between 1995 and 2010. Patient demographics, comorbidities, socioeconomic status, mechanism of injury, fracture type, classification, method of fixation, and outcome were recorded using the patients’ notes. The General Register Office for Scotland was used to obtain the mortality status of the patients. There were 276 total hip replacements (THR), 123 total knee replacements (TKR), 117 hemiarthroplasty, and 114 “other” implants. The incidence of periprosthetic fractures increased significantly during the study period for all implants: THR (p<0.001), TKR (p<0.001), hemiarthroplasty (p=0.002), and other (p=0.003). The majority of fractures were fixed by open reduction and internal fixation (72%). This failed in 14% of THR, 15% of TKR, 21% of hemiarthroplasties, and 18% of “other” implants. Isolated independent predictors of failure of fixation, after multivariate regression analysis, were increasing age, deprivation, a past medical history of asthma or chronic obstructive airways disease, osteoporosis, and steroid use (p<0.05). Failure of fixation was associated with a significantly increased one year mortality rate (OR 12.5, p=0.003). Periprosthetic fractures involving THR and TKR are becoming more prevalent. Patient demographics can be used to calculate the risk of failure of fixation, and those with an increased risk may benefit from revision of their implant, and avert the associate morbidity of failure of fixation


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

Purpose: Intimate partner violence (IPV), also known as domestic violence, is a pattern of coercive behaviors that include repeated physical, sexual and emotional abuse. Musculoskeletal injuries are common manifestations of IPV. We aimed to determine the proportion of women presenting to orthopaedic fracture clinics for treatment of orthopaedic injuries that have experienced IPV defined as physical, sexual, or emotional abuse within the past 12 months. Method: 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 (Woman Abuse Screening Tool (WAST) and the Partner Violence Screen (PVS)) to determine the prevalence of IPV.

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%) (89 of 282 women). 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, of which five were fractures.

Purpose: The aim of this study was to investigate whether distress alone or in combination with personality traits associates with low back pain (LBP) in adolescence. Materials and methods: Oulu Back Study (OBS) is a sub-cohort of the Northern Finland 1986 Birth Cohort. Data was collected at 16 and 18 years. The response rate was 69% (1987/2969). Incident cases reported LBP at 18 but not at 16, whereas persistent cases reported back pain at both time points. Distress (GHQ-12) and personality traits (hostility, optimism-pessimism, trait anxiety) were inquired at 18. Logistic regression analysis, stratified for gender, with adjustment for BMI, physical activity, smoking, parents’ socioeconomic status, sedentary hours, and sleep disturbances at 16 years was used. Additionally, the psychological determinants were mutually adjusted in the final analysis. Results: Distress was associated independently with incident LBP among boys (highest quartile vs. lowest: OR 2.47; 95% CI 1.17–5.21), whereas none of the psychological determinants were significant in incident pain among girls. Trait anxiety was associated with persistent LBP among girls (OR 2.27; 1.09–4.75), and of borderline significance with boys’ persistent pain (OR 2.40; 0.99–5.84). The combination of trait anxiety and distress (highest quartiles) associated significantly with both incident and persistent pain in both genders (OR range from 1.95 to 2.36), whereas of the other combinations of distress with personality traits only pessimism associated with persistent LBP among boys (OR 2.05). Conclusions: Perceived distress and trait anxiety, alone and especially combined with each other, associate with self-reported LBP in adolescence

Background: A general increase in total number of primary total hip arthroplasty (THA) has been observed in Denmark from 3.828 in 1995 to 7.645 in 2006. During the same period the number of pa-tients treated at private clinics has also increased. To our knowledge no studies, comparing patient characteristics and treatment quality between public and private hospitals, have been published. We compared patients’ characteristics and outcome following THA in private and public hos-pitals. Materials and Methods: We used data from the Danish Hip Arthroplasty Registry to identify 69 249 primary THA’ies performed between 1 January 1995 to 31 December 2006. To detect eventual difference in patient characteristics- age, gender, diagnosis leading to THA, Carlson’s comorbidity score and Charnley category were evaluated. We matched 3 658 cases operated in private with 3 658 controllers operated in public hospitals on propensity score. Scoring parameters were age, gender, diagnosis leading to THA, Carlson’s comorbidity score, Charnley category, operating time, type of anesthesia and type of prosthesis. We used multivariate logistic regression on propensity score matched data to assess association between type of hospital and outcome by computing relative risks and 95% Confidence Interval (CI). Outcomes were perioperative complications, readmission within 3 months, re-operation within 2 years, implant failure after 5 years, and mortality within 3 months of surgery. Results: Private hospitals operated on older females, patients with primary osteoarthritis and low comorbidity and Charnley category 1. Patients in private and propensity matched controls from public hospitals showed no differences in age, gender, diagnosis leading to THA, Carlson’s comorbidity score, Charnley category, operating time, type of anesthesia and type of prosthesis (p-value < 0,0001). Based on matched data, private hospitals had lower relative risk for perioperative complications (0.39, 0.26–0.60), reoperations (0.59, 0.41–0.83) and readmissions (0.57, 0.42–0.77) compared with public. There was no difference in mortality or implant failure. Discussion and Conclusions: We had no data on surgeon, general health and socioeconomic status of the patients. In addition, reported data from private clinics have not been validated in contrast to public hospitals. We found significant difference between patient characteristics operated at public versus private hospitals. No difference was evident regarding mortality and implant failure but for complications, reoperations and readmissions between private and public hospitals

Aims

The aim of this study was to characterize the influence of social deprivation on the rate of complications, readmissions, and revisions following primary total shoulder arthroplasty (TSA), using the Social Deprivation Index (SDI). The SDI is a composite measurement, in percentages, of seven demographic characteristics: living in poverty, with < 12 years of education, single-parent households, living in rented or overcrowded housing, households without a car, and unemployed adults aged < 65 years.

Methods

Patients aged ≥ 40 years, who underwent primary TSA between 2011 and 2017, were identified using International Classification of Diseases (ICD)-9 Clinical Modification and ICD-10 procedure codes for TSA in the New York Statewide Planning and Research Cooperative System database. Readmission, reoperation, and other complications were analyzed using multivariable Cox proportional hazards regression controlling for SDI, age, ethnicity, insurance status, and Charlson Comorbidity Index.

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. This study aimed to identify the impact of deprivation on patients on growing waiting lists for planned care.

Methods

Questionnaires were sent to orthopaedic waiting list patients at the start of the UK’s first COVID-19 lockdown to capture key quantitative and qualitative aspects of patients’ health. A total of 888 respondents were divided into quintiles, with sampling stratified based on the Index of Multiple Deprivation (IMD); level 1 represented the ‘most deprived’ cohort and level 5 the ‘least deprived’.

Aims

The aim of this study was to estimate time to arthroplasty among patients with hip and knee osteoarthritis (OA), and to identify factors at enrolment to first-line intervention that are prognostic for progression to surgery.

Methods

In this longitudinal register-based observational study, we identified 72,069 patients with hip and knee OA in the Better Management of Patients with Osteoarthritis Register (BOA), who were referred for first-line OA intervention, between May 2008 and December 2016. Patients were followed until the first primary arthroplasty surgery before 31 December 2016, stratified into a hip and a knee OA cohort. Data were analyzed with Kaplan-Meier and multivariable-adjusted Cox regression.

Background: To our knowledge, there are no publications that have evaluated physical activities in relation to the etiology of AIS other than sport scoliosis (1,2) so we undertook a study to assess the physical activities of patients with progressive AIS from their first year to early teens and compared these with those of a control group. Methods: All 156 children in this study had to adhere to the following 6 criteria:- born full term, fed well as infants, achieved their milestones, no hospital visits except for sports injuries, no family history of a scoliosis and no back pain (prior to diagnosis in the patient group). We compared 79 consecutive patients (girls 66, boys 13) diagnosed as progressive AIS (62 of whom subsequently had a spinal fusion) with a control group of 77 subjects (girls 66, boys 11) of similar age, gender, race and socioeconomic status. A structured history was obtained from the mother and child of each group average time taken to obtain the history was 47 minutes. Each child was examined for toe touching and vertical symmetry of spinous processes whilst standing. The findings suggest a relation between physical activities or the lack of them and the development of progressive AIS. Results: There is a significantly increased odds of AIS in those who were introduced to a swimming pool within the first year of life (p=0.001), did not attend gymnastics/ karate classes (p=0.005), did not attend dance classes (girls only, p=0.045), did not have horse riding classes (p=0.003), did not go skating (< 0.001), and who could touch their toes (p=0.011). No association is found with playing football/hockey or regular swimming at the age of 10 years. Conclusion: Progressive AIS is positively associated with an early introduction to swimming and ability to toe touch. Spinal asymmetry was noted in the controls. AIS is negatively associated with participation in dance, skating, gymnastics/karate and horse riding classes. Is it possible that children who develop AIS have a longstanding proprioception defect which makes them less likely to participate in sporting activities? If so, by encouraging children to participate in sport might we increase their proprioception abilities and make those at risk less likely to develop spinal asymmetry which may progress to a scoliosis requiring surgical correction?

Revision surgery is an important outcome of hip and knee arthroplasty among patients with osteoarthritis (OA). The objective of this study was to determine the risk of revision over time in a large, geographically defined population in North America, and to assess the effects of age, sex, and socioeconomic status (SES) on knee and hip revision rates in this population. We used data on admissions to all acute care hospitals in British Columbia (BC), Canada (population of four million people) from 1986 until 2004 (eighteen years of follow-up). Primary knee and hip replacement surgery for OA and revision procedures were identified using diagnostic (ICD-9, ICD-10) codes and surgical procedure codes. We excluded cases admitted due to injury or neoplasm. SES was assigned based on residential address linked to census data at the level of enumeration area (ecological variable), and analyzed according to quintiles or deciles of the distribution. In the analysis, we used Kaplan-Meier survival curves to describe the risk of first revision following first primary replacement surgery over time and parametric (Weibull) survival regression models to analyze the effects of joint (hip vs. knee) age, sex, and SES on revision rates. Death, emigration, and another primary joint replacement were treated as censoring events. Between 1986 and 2004, we observed 24,169 first primary hip replacements and 22,875 first primary knee replacements. In these patients, there were 1,313 hip revisions and 914 knee revisions following a primary replacement. The risk of revision at five, ten and fifteen years after primary replacement according to joint and sex were identified The overall risks were 10.1% for the hip and 8.7% for the knee at ten years, and 15.5% and 14.7%, respectively, at fifteen years. Risk of revision (%) following first primary joint replacement surgery Hip Knee Years Men Women Men Women 5 5.0 3.9 4.6 3.8 10 11.0 9.4 9.7 8.0 15 17.8 14.1 18.5 12.4 In a multivariate survival regression model including joint, age, sex, and SES, only age and sex were significantly associated with revisions. The hazard ratio was 1.2 for men compared with women (p< 0.0001). Revision rates were higher in younger persons, with hazard ratios increasing from 1.7 for age 70–79 (p< 0.0001) to 3.9 for age < 49 (p< 0.0001) compared with age 80+. After adjusting for age and sex, SES was not significantly associated with revision risk following primary hip or knee replacement surgery in this population (p=0.75). This is one of the largest and longest cohort studies in North America to look at the epidemiology of revision procedures following hip and knee replacement for OA. Higher rates in men and in younger persons are consistent with previous reports. The lack of association between revision risk and SES in BC is an important finding given current concerns about socioeconomic disparities in access to and outcomes of treatment for OA

Periprosthetic joint infection (PJI) remains an extremely challenging complication. We have focused on this issue more over the last decade than previously, but there are still many unanswered questions. We now have a workable definition that everyone should align to, but we need to continue to focus on identifying the organisms involved. Surgical strategies are evolving and care is becoming more patient-centred. There are some good studies under way. There are, however, still numerous problems to resolve, and the challenge of PJI remains a major one for the orthopaedic community. This annotation provides some up-to-date thoughts about where we are, and the way forward. There is still scope for plenty of research in this area.

Aims

For the increasing number of working-age patients undergoing total hip or total knee arthroplasty (THA/TKA), return to work (RTW) after surgery is crucial. We investigated the association between occupational class and time to RTW after THA or TKA.

Methods

Data from the prospective multicentre Longitudinal Leiden Orthopaedics Outcomes of Osteoarthritis Study were used. Questionnaires were completed preoperatively and six and 12 months postoperatively. Time to RTW was defined as days from surgery until RTW (full or partial). Occupational class was preoperatively assessed and categorized into four categories according to the International Standard Classification of Occupations 2008 (blue-/white-collar, high-/low-skilled). Cox regression analyses were conducted separately for THA and TKA patients. Low-skilled blue-collar work was used as the reference category.

Aims

Periprosthetic proximal femoral fractures (PFFs) are a major complication after total hip arthroplasty (THA). Health status after PFF is not specifically investigated. The aim of this study is to evaluate the health status pattern over two years after sustaining a PFF.

Methods

A cohort of patients with PFF after THA was derived from the Brabant Injury Outcomes Surveillance (BIOS) study. The BIOS study, a prospective, observational, multicentre follow-up cohort study, was conducted to obtain data by questionnaires pre-injury and at one week, and one, three, six, 12, and 24 months after trauma. Primary outcome measures were the EuroQol five-dimension three-level questionnaire (EQ-5D-3L), the Health Utility Index 2 (HUI2), and the Health Utility Index 3 (HUI3). Secondary outcome measures were general measurements such as duration of hospital stay and mortality.

Aims

To identify factors influencing clinicians’ decisions to undertake a nonoperative hip fracture management approach among older people, and to determine whether there is global heterogeneity regarding these factors between clinicians from high-income countries (HIC) and low- and middle-income countries (LMIC).

Methods

A SurveyMonkey questionnaire was electronically distributed to clinicians around the world through the Fragility Fracture Network (FFN)’s Perioperative Special Interest Group and clinicians’ personal networks between 24 May and 25 July 2021. Analyses were performed using Excel and STATA v16.0. Between-group differences were determined using independent-samples t-tests and chi-squared tests.


Aims

The aims of this study were to evaluate the incidence of reoperation (all cause and specifically for periprosthetic femoral fracture (PFF)) and mortality, and associated risk factors, following a hemiarthroplasty incorporating a cemented collarless polished taper slip stem (PTS) for management of an intracapsular hip fracture.

Methods

This retrospective study included hip fracture patients aged 50 years and older treated with Exeter (PTS) bipolar hemiarthroplasty between 2019 and 2022. Patient demographics, place of domicile, fracture type, delirium status, American Society of Anesthesiologists (ASA) grade, length of stay, and mortality were collected. Reoperation and mortality were recorded up to a median follow-up of 29.5 months (interquartile range 12 to 51.4). Cox regression was performed to evaluate independent risk factors associated with reoperation and mortality.

Aims

This study aimed to determine whether lateral femoral wall thickness (LWT) < 20.5 mm was associated with increased revision risk of intertrochanteric fracture (ITF) of the hip following sliding hip screw (SHS) fixation when the medial calcar was intact. Additionally, the study assessed the association between LWT and patient mortality.

Methods

This retrospective study included ITF patients aged 50 years and over treated with SHS fixation between 2019 and 2021 at a major trauma centre. Demographic information, fracture type, delirium status, American Society of Anesthesiologists grade, and length of stay were collected. LWT and tip apex distance were measured. Revision surgery and mortality were recorded at a mean follow-up of 19.5 months (1.6 to 48). Cox regression was performed to evaluate independent risk factors associated with revision surgery and mortality.

Aims

The escalating demand for medical resources to address spinal diseases as society ages is an issue that requires careful evaluation. However, few studies have examined trends in spinal surgery, especially unscheduled hospitalizations or surgeries performed after hours, through large databases. Our study aimed to determine national trends in the number of spine surgeries in Japan. We also aimed to identify trends in after-hours surgeries and unscheduled hospitalizations and their impact on complications and costs.

Methods

We retrospectively investigated data extracted from the Diagnosis Procedure Combination database, a representative inpatient database in Japan. The data from April 2010 to March 2020 were used for this study. We included all patients who had undergone any combination of laminectomy, laminoplasty, discectomy, and/or spinal arthrodesis.

Aims

The number of patients undergoing surgery for degenerative cervical radiculopathy has increased. In many countries, public hospitals have limited capacity. This has resulted in long waiting times for elective treatment and a need for supplementary private healthcare. It is uncertain whether the management of patients and the outcome of treatment are equivalent in public and private hospitals. The aim of this study was to compare the management and patient-reported outcomes among patients who underwent surgery for degenerative cervical radiculopathy in public and private hospitals in Norway, and to assess whether the effectiveness of the treatment was equivalent.

Methods

This was a comparative study using prospectively collected data from the Norwegian Registry for Spine Surgery. A total of 4,750 consecutive patients who underwent surgery for degenerative cervical radiculopathy and were followed for 12 months were included. Case-mix adjustment between those managed in public and private hospitals was performed using propensity score matching. The primary outcome measure was the change in the Neck Disability Index (NDI) between baseline and 12 months postoperatively. A mean difference in improvement of the NDI score between public and private hospitals of ≤ 15 points was considered equivalent. Secondary outcome measures were a numerical rating scale for neck and arm pain and the EuroQol five-dimension three-level health questionnaire. The duration of surgery, length of hospital stay, and complications were also recorded.

Aims

The aim of this study was to assess factors associated with the estimated lifetime risk of revision surgery after primary knee arthroplasty (KA).

Methods

All patients from the Scottish Arthroplasty Project dataset undergoing primary KA during the period 1 January 1998 to 31 December 2019 were included. The cumulative incidence function for revision and death was calculated up to 20 years. Adjusted analyses used cause-specific Cox regression modelling to determine the influence of patient factors. The lifetime risk was calculated as a percentage for patients aged between 45 and 99 years using multiple-decrement life table methodology.

Aims

Socioeconomic and racial disparities have been recognized as impacting the care of patients with cancer, however there are a lack of data examining the impact of these disparities on patients with bone sarcoma. The purpose of this study was to examine socioeconomic and racial disparities that impact the oncological outcomes of patients with bone sarcoma.

Methods

We reviewed 4,739 patients diagnosed with primary bone sarcomas from the Surveillance, Epidemiology and End Results (SEER) registry between 2007 and 2015. We examined the impact of race and insurance status associated with the presence of metastatic disease at diagnosis, treatment outcome, and overall survival (OS).

Aims

This study aimed to identify risk factors (patient, healthcare system, and socioeconomic) for mortality after hip fractures and estimate their relative importance. Further, we aimed to elucidate mortality and survival patterns following fractures and the duration of excess mortality.

Methods

Data on 37,394 hip fractures in the Norwegian Hip Fracture Register from January 2014 to December 2018 were linked to data from the Norwegian Patient Registry, Statistics Norway, and characteristics of acute care hospitals. Cox regression analysis was performed to estimate risk factors associated with mortality. The Wald statistic was used to estimate and illustrate relative importance of risk factors, which were categorized in modifiable (healthcare-related) and non-modifiable (patient-related and socioeconomic). We calculated standardized mortality ratios (SMRs) comparing deaths among hip fracture patients to expected deaths in a standardized reference population.

Aims

The purpose of this study was to determine the access to and ability to use telemedicine technology in adult patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA), and to determine associations with the socioeconomic characteristics of the patients, including age, sex, race, and education. We also sought to understand the patients’ perceived benefits, risks, and preferences when dealing with telemedicine.

Methods

We performed a cross-sectional survey involving patients awaiting primary THA and TKA by one of six surgeons at a single academic institution. Patients were included and called for a telephone-administered survey if their surgery was scheduled to be between 23 March and 2 June 2020, and were aged > 18 years.

Aims

Access to joint replacement is being restricted for patients with comorbidities in a number of high-income countries. However, there is little evidence on the impact of comorbidities on outcomes. The purpose of this study was to determine the safety and effectiveness of hip and knee arthroplasty in patients with and without comorbidities.

Methods

In total, 312,079 hip arthroplasty and 328,753 knee arthroplasty patients were included. A total of 11 common comorbidities were identified in administrative hospital records. Safety risks were measured by assessing length of hospital stay (LOS) and 30-day emergency readmissions and mortality. Effectiveness outcomes were changes in Oxford Hip or Knee Scores (OHS/OKS) (scale from 0 (worst) to 48 (best)) and in health-related quality of life (EQ-5D) (scale from 0 (death) to 1 (full health)) from immediately before, to six months after, surgery. Regression analysis was used to estimate adjusted mean differences (LOS, change in OHS/OKS/EQ-5D) and risk differences (readmissions and mortality).

Aims

Despite the interest in the association of gut microbiota with bone health, limited population-based studies of gut microbiota and bone mineral density (BMD) have been made. Our aim is to explore the possible association between gut microbiota and BMD.

Methods

A total of 3,321 independent loci of gut microbiota were used to calculate the individual polygenic risk score (PRS) for 114 gut microbiota-related traits. The individual genotype data were obtained from UK Biobank cohort. Linear regressions were then conducted to evaluate the possible association of gut microbiota with L1-L4 BMD (n = 4,070), total BMD (n = 4,056), and femur total BMD (n = 4,054), respectively. PLINK 2.0 was used to detect the single-nucleotide polymorphism (SNP) × gut microbiota interaction effect on the risks of L1-L4 BMD, total BMD, and femur total BMD, respectively.

Aims

This study aimed to evaluate whether an enhanced recovery protocol (ERP) for arthroplasty established during the COVID-19 pandemic at a safety net hospital can be associated with a decrease in hospital length of stay (LOS) and an increase in same-day discharges (SDDs) without increasing acute adverse events.

Methods

A retrospective review of 124 consecutive primary arthroplasty procedures performed after resuming elective procedures on 11 May 2020 were compared to the previous 124 consecutive patients treated prior to 17 March 2020, at a single urban safety net hospital. Revision arthroplasty and patients with < 90-day follow-up were excluded. The primary outcome measures were hospital LOS and the number of SDDs. Secondary outcome measures included 90-day complications, 90-day readmissions, and 30day emergency department (ED) visits.

Aims

Using tibial shaft fracture participants from a large, multicentre randomized controlled trial, we investigated if patient and surgical factors were associated with health-related quality of life (HRQoL) at one year post-surgery.

Methods

The Study to Prospectively Evaluate Reamed Intramedullary Nails in Patients with Tibial Fractures (SPRINT) trial examined adults with an open or closed tibial shaft fracture who were treated with either reamed or unreamed intramedullary nails. HRQoL was assessed at hospital discharge (for pre-injury level) and at 12 months post-fracture using the Short Musculoskeletal Functional Assessment (SMFA) Dysfunction, SMFA Bother, 36-Item Short Form 36 (SF-36) Physical, and SF-36 Mental Component scores. We used multiple linear regression analysis to determine if baseline and surgical factors, as well as post-intervention procedures within one year of fracture, were associated with these HRQoL outcomes. Significance was set at p < 0.01. We hypothesize that, irrespective of the four measures used, prognosis is guided by both modifiable and non-modifiable factors and that patients do not return to their pre-injury level of function, nor HRQoL.

Aims

In countries with social healthcare systems, such as Canada, patients may experience long wait times and a decline in their health status prior to their operation. The aim of this study is to explore the association between long preoperative wait times (WT) and acute hospital length of stay (LoS) for primary arthroplasty of the knee and hip.

Methods

The study population was obtained from the provincial Patient Access Registry Nova Scotia (PARNS) and the Canadian national hospital Discharge Access Database (DAD). We included primary total knee and hip arthroplasties (TKA, THA) between 2011 and 2017. Patients waiting longer than the recommended 180 days Canadian national standard were compared to patients waiting equal or less than the standard WT. The primary outcome measure was acute LoS postoperatively. Secondarily, patient demographics, comorbidities, and perioperative parameters were correlated with LoS with multivariate regression.

Aims

Neither a surgeon’s intraoperative impression nor the parameters of computer navigation have been shown to be predictive of the outcomes following total knee arthroplasty (TKA). The aim of this study was to determine whether a surgeon, with robotic assistance, can predict the outcome as assessed using the Knee Injury and Osteoarthritis Outcome Score (KOOS) for pain (KPS), one year postoperatively, and establish what factors correlate with poor KOOS scores in a well-aligned and balanced TKA.

Methods

A total of 134 consecutive patients who underwent TKA using a dynamic ligament tensioning robotic system with a tibia first resection technique and a cruciate sacrificing ultracongruent TKA system were enrolled into a prospective study. Each TKA was graded based on the final mediolateral ligament balance at 10° and 90° of flexion: 1) < 1 mm difference in the thickness of the tibial insert and that which was planned (n = 75); 2) < 1 mm difference (n = 26); 3) between 1 mm to 2 mm difference (n = 26); and 4) > 2 mm difference (n = 7). The mean one-year KPS score for each grade of TKA was compared and the likelihood of achieving an KPS score of > 90 was calculated. Finally, the factors associated with lower KPS despite achieving a high-grade TKA (grade A and B) were analyzed.

Aims

Time to treatment initiation (TTI) is generally defined as the time from the histological diagnosis of malignancy to the initiation of first definitive treatment. There is no consensus on the impact of TTI on the overall survival in patients with a soft-tissue sarcoma. The purpose of this study was to determine if an increased TTI is associated with overall survival in patients with a soft-tissue sarcoma, and to identify the factors associated with a prolonged TTI.

Methods

We identified 23,786 patients from the National Cancer Database who had undergone definitive surgery between 2004 and 2015 for a localized high-grade soft-tissue sarcoma of the limbs or trunk. A Cox proportional hazards model was used to examine the relationship between a number of factors and overall survival. We calculated the incidence rate ratio (IRR) using negative binomial regression models to identify the factors that affected TTI.

Aims

It is imperative to understand the risks of operating on urgent cases during the COVID-19 (SARS-Cov-2 virus) pandemic for clinical decision-making and medical resource planning. The primary aim was to determine the mortality risk and associated variables when operating on urgent cases during the COVID-19 pandemic. The secondary objective was to assess differences in the outcome of patients treated between sites treating COVID-19 and a separate surgical site.

Methods

The primary outcome measure was 30-day mortality. Secondary measures included complications of surgery, COVID-19 infection, and length of stay. Multiple variables were assessed for their contribution to the 30-day mortality. In total, 433 patients were included with a mean age of 65 years; 45% were male, and 90% were Caucasian.

Aims

Complex fractures of the femur and tibia with associated severe soft tissue injury are often devastating for the individual. The aim of this study was to describe the two-year patient-reported outcomes of patients in a civilian population who sustained a complex fracture of the femur or tibia with a Mangled Extremity Severity Score (MESS) of ≥ 7, whereby the score ranges from 2 (lowest severity) to 11 (highest severity).

Methods

Patients aged ≥ 16 years with a fractured femur or tibia and a MESS of ≥ 7 were extracted from the Victorian Orthopaedic Trauma Outcomes Registry (January 2007 to December 2018). Cases were grouped into surgical amputation or limb salvage. Descriptive analysis were used to examine return to work rates, three-level EuroQol five-dimension questionnaire (EQ-5D-3L), and Glasgow Outcome Scale-Extended (GOS-E) outcomes at 12 and 24 months post-injury.

Aims

Echocardiography is commonly used in hip fracture patients to evaluate perioperative cardiac risk. However, echocardiography that delays surgical repair may be harmful. The objective of this study was to compare surgical wait times, mortality, length of stay (LOS), and healthcare costs for similar hip fracture patients evaluated with and without preoperative echocardiograms.

Methods

A population-based, matched cohort study of all hip fracture patients (aged over 45 years) in Ontario, Canada between 2009 and 2014 was conducted. The primary exposure was preoperative echocardiography (occurring between hospital admission and surgery). Mortality rates, surgical wait times, postoperative LOS, and medical costs (expressed as 2013$ CAN) up to one year postoperatively were assessed after propensity-score matching.

Aims

The impact of tobacco use on readmission and medical and surgical complications has been documented in hip and knee arthroplasty. However, there remains little information about the effect of smoking on the outcome after total shoulder arthroplasty (TSA). We hypothesized that active smokers are at an increased risk of poor medical and surgial outcomes after TSA.

Methods

Data for patients who underwent arthroplasty of the shoulder in the USA between January 2011 and December 2015 were obtained from the National Readmission Database, and 90-day readmissions and complications were documented using validated coding methods. Multivariate regression analysis was performed to quantify the risk of smoking on the outcome after TSA, while controlling for patient demographics, comorbidities, and hospital-level confounding factors.

Aims

Perthes’ disease is a condition leading to necrosis of the femoral head. It is most common in children aged four to nine years, affecting around one per 1,200 children in the UK. Management typically includes non-surgical treatment options, such as physiotherapy with/without surgical intervention. However, there is significant variation in care with no consensus on the most effective treatment option.

Methods

This systematic review aims to evaluate the effectiveness of non-surgical interventions for the treatment of Perthes’ disease. Comparative studies (experimental or observational) of any non-surgical intervention compared directly with any alternative intervention (surgical, non-surgical or no intervention) were identified from: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMcare, Allied and Complementary Medicine Database (AMED), and the Physiotherapy Evidence Database (PEDro). Data were extracted on interventions compared and methodological quality. For post-intervention primary outcome of radiological scores (Stulberg and/or Mose), event rates for poor scores were calculated with significance values. Secondary outcomes included functional measures, such as range of movement, and patient-reported outcomes such as health-related quality of life.

Evidence suggests that the alleviation of pain is enhancedby a strong patient-clinician relationship and attending to a patient’s social and mental health. There is a limited role for medication, opioids in particular.

Orthopaedic surgeons can use comprehensive biopsychosocial strategies to help people recover and can work with colleagues who have the appropriate expertise in order to maximize pain alleviation with optimal opioid stewardship.

Preparing patients for elective surgery and caring for them after unplanned injury or surgery can benefit from planned and practiced strategies based in communication science.

Aims

Few risk factors for rotator cuff disease (RCD) and corresponding treatment have been firmly established. The aim of this study was to evaluate the relationship between numerous risk factors and the incidence of surgery for RCD in a large cohort.

Methods

A population-based cohort of people aged between 40 and 69 years in the UK (the UK Biobank) was studied. People who underwent surgery for RCD were identified through a link with NHS inpatient records covering a mean of eight years after enrolment. Multivariate Cox proportional hazards regression was used to calculate hazard ratios (HRs) as estimates of associations with surgery for RCD accounting for confounders. The risk factors which were considered included age, sex, race, education, Townsend deprivation index, body mass index (BMI), occupational demands, and exposure to smoking.

Aims

Patients may present with concurrent symptomatic osteoarthritis (OA) of the hip and degenerative disorders of the lumbar spine, with surgical treatment being indicated for both. Whether arthroplasty of the hip or spinal surgery should be performed first remains uncertain.

Materials and Methods

Clinical scenarios were devised for a survey asking the preferred order of surgery and the rationale for this decision for five fictional patients with both OA of the hip and degenerative lumbar disorders. These were symptomatic OA of the hip and: 1) lumbar spinal stenosis with neurological claudication; 2) lumbar degenerative spondylolisthesis with leg pain; 3) lumbar disc herniation with leg weakness; 4) lumbar scoliosis with back pain; and 5) thoracolumbar disc herniation with myelopathy. This survey was sent to 110 members of The Hip Society and 101 members of the Scoliosis Research Society. The choices of the surgeons were compared among scenarios and between surgical specialties using the chi-squared test. The free-text comments were analyzed using text-mining.

Aims

It is uncertain whether instrumented spinal fixation in nonambulatory children with neuromuscular scoliosis should finish at L5 or be extended to the pelvis. Pelvic fixation has been shown to be associated with up to 30% complication rates, but is regarded by some as the standard for correction of deformity in these conditions. The incidence of failure when comparing the most caudal level of instrumentation, either L5 or the pelvis, using all-pedicle screw instrumentation has not previously been reported. In this retrospective study, we compared nonambulatory patients undergoing surgery at two centres: one that routinely instrumented to L5 and the other to the pelvis.

Methods

In all, 91 nonambulatory patients with neuromuscular scoliosis were included. All underwent surgery using bilateral, segmental, pedicle screw instrumentation. A total of 40 patients underwent fusion to L5 and 51 had their fixation extended to the pelvis. The two groups were assessed for differences in terms of clinical and radiological findings, as well as complications.

Aims

There is an increasing demand for hip arthroplasty in China. We aimed to describe trends in in-hospital mortality after this procedure in China and to examine the potential risk factors.

Patients and Methods

We included 210 450 patients undergoing primary hip arthroplasty registered in the Hospital Quality Monitoring System in China between 2013 and 2016. In-hospital mortality after hip arthroplasty and its relation to potential risk factors were assessed using multivariable Poisson regression.

Aims

As the population ages, there is projected to be an increase in the level of demand for total knee arthroplasty (TKA) in octogenarians. We aimed to explore whether those aged ≥ 80 years achieved similar improvements in physical function to younger patients while also comparing the rates of length of stay (LOS), discharge to rehabilitation, postoperative complications, and mortality following TKA in older and younger patients.

Patients and Methods

Patients from one institution who underwent primary elective TKA between 1 January 2006 and 31 December 2014 were dichotomized into those ≥ 80 years old (n = 359) and those < 80 years old (n = 2479) for comparison. Multivariable regression was used to compare the physical status component of the 12-Item Short-Form Health Survey (SF-12), LOS, discharge to rehabilitation, complications, and mortality between the two groups.

Aims

The primary aim of this study was to quantify the improvement in patient-reported outcome measures (PROMs) following total hip arthroplasty (THA), as well as the extent of any deterioration through the seven-year follow-up. The secondary aim was to identify predictors of PROM improvement and deterioration.

Patients and Methods

A total of 976 patients were enrolled into a prospective, international, multicentre study. Patients completed a battery of PROMs prior to THA, at three months post-THA, and at one, three, five, and seven-years post-THA. The Harris Hip Score (HHS), the 36-Item Short-Form Health Survey (SF-36) Physical Component Summary (PCS), the SF-36 Mental Component Summary (MCS), and the EuroQol five-dimension three-level (EQ-5D) index were the primary outcomes. Longitudinal changes in each PROM were investigated by piece-wise linear mixed effects models. Clinically significant deterioration was defined for each patient as a decrease of one half of a standard deviation (group baseline).

Aims

To evaluate the influence of discharge timing on 30-day complications following total knee arthroplasty (TKA).

Patients and Methods

We identified patients aged 18 years or older who underwent TKA between 2005 and 2016 from the American College of Surgeons’ National Surgical Quality Improvement Program (NSQIP) database. We propensity score-matched length-of-stay (LOS) groups using all relevant covariables. We used multivariable regression to determine if the rate of complications and re-admissions differed depending on LOS.

Aims

Displaced femoral neck fractures (FNF) may be treated with partial (hemiarthroplasty, HA) or total hip arthroplasty (THA), with recent recommendations advising that THA be used in community-ambulant patients. This study aims to determine the association between the proportion of FNF treated with THA and year of surgery, day of the week, surgeon practice, and private versus public hospitals, adjusting for known confounders.

Patients and Methods

Data from 67 620 patients in the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) from 1999 to 2016 inclusive were used to generate unadjusted and adjusted analyses of the associations between patient, time, surgeon and institution factors, and the proportion of FNF treated with THA.

Aims

Few studies have compared survivorship of total shoulder arthroplasty (TSA) with hemiarthroplasty (HA). This observational study compared survivorship of TSA with HA while controlling for important covariables and accounting for death as a competing risk.

Patients and Methods

All patients who underwent shoulder arthroplasty in Ontario, Canada between April 2002 and March 2012 were identified using population-based health administrative data. We used the Fine–Gray sub-distribution hazard model to measure the association of arthroplasty type with time to revision surgery (accounting for death as a competing risk) controlling for age, gender, Charlson Comorbidity Index, income quintile, diagnosis, and surgeon factors.

Paediatric fractures are common and can cause significant morbidity. Socioeconomic deprivation is associated with an increased incidence of fractures in both adults and children, but little is known about the epidemiology of paediatric fractures. In this study we investigated the effect of social deprivation on the epidemiology of paediatric fractures.

We compiled a prospective database of all fractures in children aged < 16 years presenting to the study centre. Demographics, type of fracture, mode of injury and postcode were recorded. Socioeconomic status quintiles were assigned for each child using the Scottish Index for Multiple Deprivation (SIMD).

We found a correlation between increasing deprivation and the incidence of fractures (r = 1.00, p < 0.001). In the most deprived group the incidence was 2420/100 000/yr, which diminished to 1775/100 000/yr in the least deprived group.

The most deprived children were more likely to suffer a fracture as a result of a fall (odds ratio (OR) = 1.5, p < 0.0001), blunt trauma (OR = 1.5, p = 0.026) or a road traffic accident (OR = 2.7, p < 0.0001) than the least deprived.

These findings have important implications for public health and preventative measures.

Aims

Using a systematic review, we investigated whether there is an increased risk of post-operative infection in patients who have received an intra-articular corticosteroid injection to the hip for osteoarthritis prior to total hip arthroplasty (THA).

Methods

Studies dealing with an intra-articular corticosteroid injection to the hip and infection following subsequent THA were identified from databases for the period between 1990 to 2013. Retrieved articles were independently assessed for their methodological quality.

Aims

A high rate of suicide has been reported in patients who sustain fractures, but the association remains uncertain in the context of other factors. The aim of this study was to examine the association between fractures and the risk of suicide in this contextual setting.

Patients and Methods

We performed a case-control study of patients aged 40 years or older who died by suicide between 2000 and 2011. We included patients’ demographics, physical and mental health problems, and socioeconomic factors. We performed conditional logistic regression to evaluate the associations between fractures and the risk of suicide.

Aims

The best method of treating unstable pelvic fractures that involve the obturator ring is still a matter for debate. This study compared three methods of treatment: nonoperative, isolated posterior fixation and combined anteroposterior stabilization.

Patients and Methods

The study used data from the German Pelvic Trauma Registry and compared patients undergoing conservative management (n = 2394), surgical treatment (n = 1345) and transpubic surgery, including posterior stabilization (n = 730) with isolated posterior osteosynthesis (n = 405) in non-complex Type B and C fractures that only involved the obturator ring anteriorly. Calculated odds ratios were adjusted for potential confounders. Outcome criteria were intraoperative and general short-term complications, the incidence of nerve injuries, and mortality.

Controversy remains whether the contralateral hip should be fixed in patients presenting with unilateral slipped capital femoral epiphysis (SCFE). This retrospective study compares the outcomes and cost of those patients who had prophylactic fixation with those who did not.

Between January 2000 and December 2010 a total of 50 patients underwent unilateral fixation and 36 had prophylactic fixation of the contralateral hip. There were 54 males and 32 females with a mean age of 12.3 years (9 to 16). The rate of a subsequent slip without prophylactic fixation was 46%. The risk of complications was greater, the generic health measures (Short Form-12 physical (p < 0.001) and mental (p = 0.004) summary scores) were worse. Radiographic cam lesions in patients presenting with unilateral SCFE were only seen in patients who did not have prophylactic fixation. Furthermore, prophylactic fixation of the contralateral hip was found to be a cost-effective procedure, with a cost per quality adjusted life year gained of £1431 at the time of last follow-up.

Prophylactic fixation of the contralateral hip is a cost-effective operation that limits the morbidity from the complications of a further slip, and the diminished functional outcome associated with unilateral fixation.

Aims

The purpose of this study is to determine if higher volume hospitals have lower costs in revision hip and knee arthroplasty.

Materials and Methods

We questioned the Centres for Medicare and Medicaid Services (CMS) Inpatient Charge Data and identified 789 hospitals performing a total of 29 580 revision arthroplasties in 2014. Centres were dichotomised into high-volume (performing over 50 revision cases per year) and low-volume. Mean total hospital-specific charges and inpatient payments were obtained from the database and stratified based on Diagnosis Related Group (DRG) codes. Patient satisfaction scores were obtained from the multiyear CMS Hospital Compare database.
