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. Results. For patient and surgical factors, only pre-injury quality of life and isolated fracture showed a statistical effect on all four HRQoL outcomes, while high-energy injury mechanism, smoking, and race or ethnicity, demonstrated statistical significance for three of the four HRQoL outcomes. Patients who did not require reoperation in response to infection, the need for bone grafts, and/or the need for implant exchanges had statistically superior HRQoL outcomes than those who did require intervention within one year after initial tibial fracture nailing. Conclusion. We identified several baseline patient factors, surgical factors, and post-intervention procedures within one year after intramedullary nailing of a tibial shaft fracture that may influence a patient’s HRQoL.

This international multicentre retrospective cohort study aimed to assess: 1) prevalence of COVID-19 in hip fracture patients, 2) effect on mortality, and 3) clinical factors associated mortality among COVID-19-positive patients. A collaboration among 112 centres in 14 nations collected data on all patients with a hip fracture between 1st March-31st May 2020. Patient, injury and surgical factors were recorded, and outcome measures included admission duration, COVID-19 and 30-day mortality status. There were 7090 patients and 651 (9.2%) were COVID-19-positive. COVID-19 was independently associated with male sex (p=0.001), residential care (p<0.001), inpatient fall (p=0.003), cancer (p=0.009), ASA grade 4–5 (p=0.008; p<0.001), and longer admission (p<0.001). Patients with COVID-19 had a significantly lower chance of 30-day survival versus those without (72.7% versus 92.6%, p<0.001), and COVID-19 was independently associated with increased 30-day mortality risk (p<0.001). Increasing age (p=0.028), male sex (p<0.001), renal (p=0.017) and pulmonary disease (p=0·039) were independently associated with higher 30-day mortality risk in patients with COVID-19 when adjusting for confounders. The prevalence of COVID-19 in hip fracture patients was 9% and was independently associated with a three-fold increased 30-day mortality risk. Clinical factors associated with mortality among COVID-19-positive hip fracture patients were identified for the first time. This is the largest study, and the only global cohort, reporting on the effect of COVID-19 in hip fracture patients. The findings provide a benchmark against which to determine vaccine efficacy in this vulnerable population and are especially important in the context of incomplete vaccination programmes and the emergence of vaccine-resistant strains

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).

Aims

To determine if patient ethnicity among patients with a hip fracture influences the type of fracture, surgical care, and outcome.

Aims

Postoperative malalignment of the femur is one of the main complications in distal femur fractures. Few papers have investigated the impact of intraoperative malalignment on postoperative function and bone healing outcomes. The aim of this study was to investigate how intraoperative fracture malalignment affects postoperative bone healing and functional outcomes.

Aims

The aim of this study was to investigate the potentially increased risk of dislocation in patients with neurological disease who sustain a femoral neck fracture, as it is unclear whether they should undergo total hip arthroplasty (THA) or hemiarthroplasty (HA). A secondary aim was to investgate whether dual-mobility components confer a reduced risk of dislocation in these patients.

Introduction. Acetabular cup positioning has been linked to dislocation and increased bearing surface wear. A previous study found correlations between patient and surgical factors and acetabular component position. The purpose of this study was to determine if acetabular cup positioning improves when surgeons receive feedback on their performance. Methods. Post-op anteroposterior (AP) pelvis and cross-table lateral radiographs were previously obtained for 2061 patients who received a total hip arthroplasty (THA) or hip resurfacing from 2004–2008. The surgeries were performed by 7 surgeons. AP radiographs were measured using Hip Analysis Suite to calculate the cup inclination and version angles. Acceptable ranges were defined for abduction (30–45 °) and version (5–25 °). The same surgeons performed a THA or hip resurfacing on 385 patients from January 2009 through June 2010. Cup inclination and version angles for this set of surgeries were compared to surgeries from 2004–2008 to determine if cup inclination and version angles improved in response to previous acetabular cup positioning studies. Improvement in accuracy was assessed by the chi-square test. Results. Time 1, from 2004 through 2008, had 1952 qualifying hips with 1845 having both version and abduction, and Time 2, from 2009 through June 2010, had 385 qualifying hips, all of which had both version and abduction angles. For Time 1, 1192 (62%) acetabular cups were within the abduction range, 1422 (79%) were within the version range, and 908 (49%) were within the range for both. For Time 2, 276 (72%) acetabular cups were within the abduction range, 250 (65%) were within the version range, and 217 (56%) were within the ranges for both. Accuracy of abduction angle improved (p<0.01) while accuracy of version angle decreased (p<0.01). Accuracy of acetabular cup positioning being within range for both abduction angle and version angle improved significantly (p=0.01), by 7%. Conclusions. Increased awareness and feedback on the resulting abduction and version measurements from THA surgery over time improves the positioning of the acetabular component. A system where objective measurements are presented to the surgeon can significantly improve cup placement which could improve the clinical outcome of THR patients

Introduction. Stiffness of the knee after total knee arthroplasty (TKA) impairs knee function and reduces patient satisfaction. Limited preoperative range of motion (ROM) and a diagnosis of osteoarthritis seem to be associated with postoperative stiffness, and medical comorbidities such as diabetes mellitus have been discussed as predisposing factors. The present study was undertaken in order to analyse both patient-related and surgical factors that could be associated with the need for mobilization under anaesthesia (MUA) after TKA. Methods. We designed a case-control-study and extracted the study population from our local arthroplasty register. We identified all patients in our register that required MUA following primary TKA (n=35) and then randomly selected 4 control patients for each case of MUA. Incomplete medical records resulted in the exclusion of 18 patients, leaving 157 patients. Univariate analysis was used in order to investigate differences between the two groups with respect to demographics, pre- and postoperative ROM, medical or psychiatric comorbidities, and the type of implant. Variables with a proposed influence on outcome were entered into a binary logistic regression model, and risk ratios (RR) were calculated with 95% confidence intervals (CI). Results. Regression analysis showed that age at operation, the presence of chronic obstructive lung disease (COLD), and preoperative flexion significantly affected outcome: Increasing age decreased the risk for needing MUA with a RR of 0.88 (CI 0.82–0.94, p<0.001) per year. Patients with COLD had significantly higher risk of needing MUA with a RR of 9.82 (CI 1.84–52.3, p=0.007). Impaired preoperative flexion was an important predictor of postoperative stiffness with a RR of 0.97 (CI 0.95–0.99, p=0.027), implicating that the risk for MUA decreased by approximately 3% for each additional degree of flexion. Gender, BMI, cardiovascular comorbidity, the presence of rheumatoid arthritis, diabetes mellitus, previous knee injury, and the type of implant did not significantly affect the risk for MUA. In univariate analysis, patients requiring MUA had significantly lower knee flexion at discharge than control patients (78° vs. 61°, p<0.001). Interpretation. We conclude that the presence of COLD, impaired preoperative knee flexion, and younger age increase the risk for needing MUA after primary TKA. The finding that COLD increases the risk for MUA is novel: It is known that patients with COLD have higher systemic levels of inflammatory mediators, and we are tempted to speculate that postoperative arthrofibrosis could be a result of enhanced systemic inflammatory activity. In our hands, the choice of implant and comorbidities other than COLD were not associated with an increased risk for MUA

Aims

Patient engagement in adaptive health behaviours and interactions with their healthcare ecosystem can be measured using self-reported instruments, such as the Patient Activation Measure (PAM-13) and the Effective Consumer Scale (ECS-17). Few studies have investigated the influence of patient engagement on limitations (patient-reported outcome measures (PROMs)) and patient-reported experience measures (PREMs). First, we assessed whether patient engagement (PAM-13, ECS-17) within two to four weeks of an upper limb fracture was associated with limitations (the Quick Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH), and Patient-Reported Outcome Measurement Information System Upper Extremity Physical Function computer adaptive test (PROMIS UE PF) scores) measured six to nine months after fracture, accounting for demographic, clinical, and psychosocial factors. Secondly, we assessed the association between patient engagement and experience (numerical rating scale for satisfaction with care (NRS-C) and satisfaction with services (NRS-S) six to nine months after fracture.

Aims

The aim of this study was to investigate the association between the type of operation used to treat a trochanteric fracture of the hip and 30-day mortality.

Several studies have reported the rate of post-operative mortality after the surgical treatment of a fracture of the hip, but few data are available regarding the delayed morbidity. In this prospective study, we identified 568 patients who underwent surgery for a fracture of the hip and who were followed for one year. Multivariate analysis was carried out to identify possible predictors of mortality and morbidity. The 30-day, four-month and one-year rates of mortality were 4.3%, 11.4%, and 18.8%, respectively. General complications and pre-operative comorbidities represented the basic predictors of mortality at any time interval (p < 0.01). In-hospital, four-month and one-year general complications occurred in 29.4%, 18.6% and 6.7% of patients, respectively. After adjusting for confounding variables, comorbidities and poor cognitive status determined the likelihood of early and delayed general complications, respectively (p < 0.001). Operative delay was the main predictor of the length of hospital stay (p < 0.001) and was directly related to in-hospital (p = 0.017) and four-month complications (p = 0.008).

We performed a retrospective study of a departmental database to assess the efficacy of a new model of orthopaedic care on the outcome of patients with a fracture of the proximal femur. All 1578 patients admitted to a university teaching hospital with a fracture of the proximal femur between December 2007 and December 2009 were included. The allocation of Foundation doctors years 1 and 2 was restructured from individual teams covering several wards to pairs covering individual wards. No alterations were made in the numbers of doctors, their hours, out-of-hours cover, or any other aspect of standard patient care. Outcome measures comprised 30-day mortality and cause, complications and length of stay. Mortality was reduced from 11.7% to 7.6% (p = 0.007, Cox’s regression analysis); adjusted odds ratio was 1.559 (95% confidence interval 1.128 to 2.156). Reductions were seen in Clostridium difficile colitis (p = 0.017), deep wound infection (p = 0.043) and gastrointestinal haemorrhage (p = 0.033). There were no differences in any patient risk factors (except the prevalence of chronic obstructive pulmonary disease), cause of death and length of stay before and after intervention. The underlying mechanisms are unclear, but may include improved efficiency and medical contact time.

These findings may have implications for all specialties caring for patients on several wards, and we believe they justify a prospective trial to further assess this effect.

The incidence of deep-vein thrombosis and the need for thromboprophylaxis following isolated trauma below the knee is uncertain. We have investigated this with a prospective randomised double-blind controlled trial using low molecular weight heparin with saline injection as placebo in patients aged between 18 and 75 years who had sustained an isolated fracture below the knee which required operative fixation. All patients had surgery within 48 hours of injury and were randomised to receive either the placebo or low molecular weight heparin for 14 days, after which they underwent bilateral lower limb venography, interpreted by three independent radiologists. Further follow-up was undertaken at two, six, eight and 12 weeks.

A total of 238 patients fulfilled all the inclusion criteria, with 127 in the low molecular weight heparin group and 111 in the placebo group, all of whom underwent bilateral venography. There was no statistically significant difference in the incidence of deep-vein thrombosis between those patients treated with low molecular weight heparin or the placebo (p = 0.22). The number of deep-vein thromboses in the two groups was 11 (8.7%) and 14 (12.6%), respectively. Age and the type of fracture were significantly associated with the rate of deep-vein thrombosis (p = 0.001 and p = 0.009, respectively) but gender, comorbidities and the body mass index were not.

The overall incidence of deep-vein thrombosis in this series was 11%. There was no clinical or statistical significant reduction in the incidence of deep-vein thrombosis with the use of thromboprophylaxis. However, we accept that owing to a cessation of funding, recruitment to this trial had to be ended prior to establishing the necessary sample size. Our results cannot, therefore, categorically exclude the possibility that low molecular weight heparin treatment could be beneficial. We recommend a further multicentre trial be undertaken to resolve this matter.

Prospective data on hip fracture from 3686 patients at a United Kingdom teaching hospital were analysed to investigate the risk factors, financial costs and outcomes associated with deep or superficial wound infections after hip fracture surgery.

In 1.2% (41) of patients a deep wound infection developed, and 1.1% (39) had a superficial wound infection. A total of 57 of 80 infections (71.3%) were due to Staphylococcus aureus and 39 (48.8%) were due to MRSA.

No statistically significant pre-operative risk factors were detected. Length of stay, cost of treatment and pre-discharge mortality all significantly increased with deep wound infection. The one-year mortality was 30%, and this increased to 50% in those who developed an infection (p < 0.001). A deep infection resulted in doubled operative costs, tripled investigation costs and quadrupled ward costs.

MRSA infection increased costs, length of stay, and pre-discharge mortality compared with non-MRSA infection.
