Aims

Several studies have reported that patients presenting during the evening or weekend have poorer quality healthcare. Our objective was to examine how timely surgery for patients with severe open tibial fracture varies by day and time of presentation and by type of hospital. This cohort study included patients with severe open tibial fractures from the Trauma Audit and Research Network (TARN).

Aims

This study aimed to compare mortality in trochanteric AO/OTA A1 and A2 fractures treated with an intramedullary nail (IMN) or sliding hip screw (SHS). The primary endpoint was 30-day mortality, with secondary endpoints at 0 to 1, 2 to 7, 8 to 30, 90, and 365 days.

Aims. Acetabular fractures in older adults lead to a high risk of mortality and morbidity. However, only limited data have been published documenting functional outcomes in such patients. The aims of this study were to describe outcomes in patients aged 60 years and older with operatively managed acetabular fractures, and to establish predictors of conversion to total hip arthroplasty (THA). Methods. We conducted a retrospective, registry-based study of 80 patients aged 60 years and older with acetabular fractures treated surgically at The Alfred and Royal Melbourne Hospital. We reviewed charts and radiological investigations and performed patient interviews/examinations and functional outcome scoring. Data were provided by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). Survival analysis was used to describe conversion to THA in the group of patients who initially underwent open reduction and internal fixation (ORIF). Multivariate regression analyses were performed to identify factors associated with conversion to THA. Results. Seven patients (8.8%) had died at a median follow-up of 18 months (interquartile range (IQR) 12 to 25), of whom four were in the acute THA group. Eight patients (10%) underwent acute THA. Of the patients who underwent ORIF, 17/72 (23.6%) required conversion to THA at a median of 10.5 months (IQR 4.0 to 32.0) . After controlling for other factors, transport-related cases had an 88% lower rate of conversion to THA (hazard ratio (HR) 0.12, 95% confidence interval (CI) 0.02 to 0.91). Mean standardized Physical Component Summary Score (PCS-12) of the 12-Item Short Form Health Survey (SF-12) was comparable with the general population (age-/sex-matched) by 12 to 24 months. Over half of patients working prior to injury (14/26) returned to work by six months and two-thirds of patients (19/27) by 12 months. Conclusion. Patients over 60 years of age managed operatively for displaced acetabular fractures had a relatively high mortality rate and a high conversion rate to THA in the ORIF group but, overall, patients who survived had mean PCS-12 scores that improved over two years and were comparable with controls.

Background. Proximal humeral fractures are common and a minority develop non-union, which can result in pain and disability. We aimed to identify the risk factors and quantify the prevalence of non-union. Methods. A thirteen-year retrospective study of 7039 patients with proximal humeral fractures was performed and a database created. 246 patients with non-union were compared to a control group to identify risk factors. Logistic regression analyses were performed to identify significant variables obtained at presentation to predict non-union. Results. The crude rate of non-union after any proximal humeral fracture is 3.5%, rising to 5.6% after excluding patients with isolated tuberosity fractures or those who underwent primary fixation. 179 patients with non-union were compared to a control group of 295 patients whose fractures healed. There was no significant difference between the groups and the entire study population in terms of age, gender and mechanism of injury. Univariate and multivariate logistic regression analyses identified 3 significant predictors for non-union: displacement of fracture (p<0.001); having a two-part fracture (p = 0.045); and varus angulation of the humeral head at injury (p<0.001). Conclusions. The prevalence of non-union of proximal humeral fractures (3.2/100,000population/year) is higher than previously appreciated and a modified classification (ongoing) is needed to include the identified risk factors

Aims

Frailty greatly increases the risk of adverse outcome of trauma in older people. Frailty detection tools appear to be unsuitable for use in traumatically injured older patients. We therefore aimed to develop a method for detecting frailty in older people sustaining trauma using routinely collected clinical data.

Aims

Periprosthetic fractures (PPFs) following hip arthroplasty are complex injuries. This study evaluates patient demographic characteristics, management, outcomes, and risk factors associated with PPF subtypes over a decade.

Aims. The aim of this study was to statistically analyse the incidence and distribution of humerus fractures in the adult age group between 3rd and 10th decades. Methods. The total number of patients was retrieved from the audit department of the hospital using the codes to identify patients between 1997 and 2009. The data included total number of patients aged 20 to 100 years who were either reviewed in the fracture clinics or admitted to the hospital with forearm fractures along with patient gender, age at the time of incident and time of the year the incident occurred. Annual incidence of fractures along with the distribution of fracture incidence per year and per individual month was calculated. The patients’ age were classified in to 3rd to 10th decades. Linear regression analysis was carried out to identify the relationship between fracture incidence and the age or time of the injury. Correlation coefficients(R) and r2 were calculated for all the regression analyses. SPSS (version 16) and Microsoft Excel 2007 were used for statistics. Results. A total of 1280 fractures were identified that included 524 males and 756 females (F/M=1.44). The average age of patients was 60.87 years. Comparing the different months of the year for fracture incidence, the average of incidence of fractures was found to be highest in july per year. There was a linear increase in the incidence of fractures from january to september (R=0.94, r2=0.89) followed by a drop in subsequent months. The total number of humerus fractures per year increased from49 in 1997 to 137 in 2009. In both males and females, there was strong relation to linearity in the increase in the incidence of fractures per year from 1997 to 2009 (Females: R=0.89, r2=0.79, Males: R=0.87, r2=0.76). On comparison of the linear equations for males and females, the rate of increase in the incidence of fractures in females was found to be approximately 1.5 times that of males. In females, There was a linear increase in the fracture incidence from the 3rd to the 9th decade (R=0.96, r2=0.92) followed by a sudden drop in the 10th decade. In men, there was a linear decrease in the fracture incidence from the 3rd to the 9th decade (r2=0.81, R=0.90). Conclusion. In the last 13 years, there has been an increase in the incidence of humerus fractures in both men and women; however, the rate of increase in the incidence in women is almost 1.5 times that of men. There was a strong correlation between age and incidence of fractures in both men and women: with increasing age, the incidence of fracture increased in women and decreased in men. The drop in fractures in women the 10th decade can be attributed to a reduced living population after 90 years. The obtained linear equations can be useful in predicting the number of fractures occurring in a certain age group in a community

INTRODUCTION. Although simulation studies have shown superior wear properties of metal-on-metal articulations, increased concern exists regarding the excess in-vivo wear of a small number of Metal-on-Metal-Hip-Resurfacing (MoMHRA) implants. Serum ion levels of Chromium (Cr) and Cobalt (Co) are surrogate markers of wear. Risk factors associated with increased wear include female gender, small components, dysplasia, cup orientation outside safe zone and femoral head downsize during surgery with an associated decrease in Head-Neck-Ratio (HNR). However, these factors are interlinked. This study aims to identify the factors that are most important for subsequent wear of MoMHRA, by performing a multivariate analysis. METHODS. 206 patients (124M: 82F) with unilateral MoMHRA were included in this study. The average follow up was 3.3 years. All patients had Cr/Co levels measured at follow up. Inclination and anteversion of each cup were measured using EBRA. Cups were analysed as being within or outside the previously defined optimum-zone. HNR measurements were made from pre-operative (HNRpre) and post-operative (HNRpost) radiographs. The immediate changes in HNR (downsize/upsize of femoral head) as a result of the operation were expressed as:. HNRprepost=HNRpost–HNRpre. Multivariate linear regression modelling was used to explore the association between measures of ions with the following predictor variables (gender, age, diagnosis, femoral component size, orientation of the acetabular component, head/neck ratio and position of femoral stem). Analyses were carried out separately for each outcome (Cr and Co). Classification and Regression Tree (CART) models were fitted as a complimentary approach to regression modelling. RESULTS. Articular surface downsize followed by cup orientation within/outside optimum zone, followed by cup anteversion followed by gender were the strongest predictors of ion levels. A percentage decrease in HNRartpost, predicted an increase in Cr ion level by 5% (and 6% for Co). If the cup was within the optimum zone this was associated with decreased levels of Cr and Co ions. As acetabular component anteversion increased, levels of ions increased. Gender had a strong effect on ion levels. Adjusting for other variables, the effect of gender was attenuated due to a confounding effect of component size and the amount of femoral head downsize. Predictors identified as important in regression analyses were similar to those produced in the CART model, where the highest levels of ions were seen in patients with a percentage decrease in pre-operative HNR −11.3. DISCUSSION. This analysis shows that (surgical) factors, such as amount of femoral head downsize at operation and whether the cup was orientated within the optimum zone, explained the majority of the variability in ion levels in MoMHRA

Aims. The aim of this study was to statistically analyse the incidence and distribution of forearm fractures in the adult age group (3rd–10th Decades) between 1997 and 2009. Methods. Records of patients with forearm fractures were retrieved from the hospital audit department using the predetermined codes to identify patients. The data included total number of patients between 20 and 100 years who were either reviewed in the fracture clinics or admitted to the hospital with forearm fractures along with patient gender, age at the time of incident and time of the year the incident occurred. Incidence of total fractures per year and per each month in the year was calculated. The patients were divided into age groups between 2nd to 10th decades. Linear regression analysis was carried out to identify the relationship between fracture incidence and the age or time of the injury. Correlation coefficients(R) and r2 were calculated for all the regression analyses. Fractures were also classified according to the Orthopaedic Trauma Association (OTA) classification system. SPSS (version 16) and Microsoft Excel 2007 were used for statistics. Results. A total of 1815 fractures were identified that included 573 males and 1242 females (F/M=2.17). The average age of patients was 59.8 years. Comparing the different months of the year for fracture incidence, the incidence of fractures was found to be highest in september per year. There was a linear increase in the incidence of fractures from January to September (R=0.9, r2=0.81) followed by a drop in subsequent months. There was a linear increase in the incidence of fractures per year from 70 in 1997 to 200 in 2009 (R=0.94, r2=0.885). Comparing the slopes of linear equations for males and females, the rate of increase in fractures in females was found to be approximately 3 times that of males. In women, There was a linear increase in the fracture incidence from the 3rd decade to the 9th decade (R=0.91, r2=0.84) followed by a sudden drop in the 10th decade. In men, there was a linear decrease in the fracture incidence from the 3rd to the 9th decade (r2=0.9559, R=0.98). 177 fractures were classified according to the OTA classification. OTA 23 type of fractures accounted for 85.3% percent of the forearm fractures followed by OTA 21 type (11.9%) and 22 type (2.8%). Further analysis showed the distribution to be: 23A-43.7%, 23B-9.9%, 23C-46.4%. Conclusion. In the last 13 years, there has been an increase in the total incidence of forearm fractures in both men and women; however, the rate of increase in women is almost 3 times that of men. With increasing age, the incidence of fracture increases in women and decreases in men. The drop in fractures in women the 10th decade can be attributed to a reduced living population after 90 years. The obtained linear equations can be useful in predicting the number of forearm fractures occurring in a certain age group in community

Aims

Heterotopic ossification (HO) is a common complication after elbow trauma and can cause severe upper limb disability. Although multiple prognostic factors have been reported to be associated with the development of post-traumatic HO, no model has yet been able to combine these predictors more succinctly to convey prognostic information and medical measures to patients. Therefore, this study aimed to identify prognostic factors leading to the formation of HO after surgery for elbow trauma, and to establish and validate a nomogram to predict the probability of HO formation in such particular injuries.

Aims

The aim of this study was to assess the association of mortality and reoperation when comparing cemented and uncemented hemiarthroplasty (HA) in hip fracture patients aged over 65 years.

Aims

The primary aim of this study was to address the hypothesis that fracture morphology might be more important than posterior malleolar fragment size in rotational type posterior malleolar ankle fractures (PMAFs). The secondary aim was to identify clinically important predictors of outcome for each respective PMAF-type, to challenge the current dogma that surgical decision-making should be based on fragment size.

Aims

The primary aim of this study was to identify independent predictors associated with nonunion and delayed union of tibial diaphyseal fractures treated with intramedullary nailing. The secondary aim was to assess the Radiological Union Scale for Tibial fractures (RUST) score as an early predictor of tibial fracture nonunion.

Aims

Complex joint fractures of the lower extremity are often accompanied by soft-tissue swelling and are associated with prolonged hospitalization and soft-tissue complications. The aim of the study was to evaluate the effect of vascular impulse technology (VIT) on soft-tissue conditioning in comparison with conventional elevation.

Aims

Hospital case volume is shown to be associated with postoperative outcomes in various types of surgery. However, conflicting results of volume-outcome relationship have been reported in hip fracture surgery. This retrospective cohort study aimed to evaluate the association between hospital case volume and postoperative outcomes in patients who had hip fracture surgery. We hypothesized that higher case volume would be associated with lower risk of in-hospital and one-year mortality after hip fracture surgery.

Aims

The primary aim was to assess the independent influence of coronavirus disease (COVID-19) on 30-day mortality for patients with a hip fracture. The secondary aims were to determine whether: 1) there were clinical predictors of COVID-19 status; and 2) whether social lockdown influenced the incidence and epidemiology of hip fractures.
