Aims. Understanding of open fracture management is skewed due to reliance on small-number lower limb, specialist unit reports and large, unfocused registry data collections. To address this, we carried out the Open Fracture Patient Evaluation
Aims. The Open-Fracture Patient Evaluation
The interest in day-case hip arthroplasty is increasing; however, there are conflicting results regarding readmission risk, and little is known about patients’ attitude towards day-case surgery. We aimed to investigate differences in 30-day readmission rates between day-case patients and single-overnight-stay patients following total hip arthroplasty (THA) and explore patients’ attitude towards day-case surgery. From the Danish National Patient Register we identified 29,486 THAs (1353 day-case THAs and 28,133 single-overnight-stay THAs) performed between 2010 and 2020. Day-case surgery was defined as discharge on the day-of-surgery. Overnight admissions within 30 days of surgery were considered readmissions. Differences in readmission rates between day-case and single-overnight-stay patients were investigated using logistic regression adjusted for patient characteristics and year of surgery. In a single-center descriptive study, 2395 hip arthroplasty patients from 2016 to start-2023 answered a questionnaire on patient characteristics, attitude towards day-case surgery and patient-reported outcome measures (PROM). The overall 30-day readmission rate was 4.4% (CI: 4.2–4.6%) with no difference between day-case (4.4%) and single-overnight-stay THAs (4.4%) (odds-ratio: 1.2 [CI: 0.91–1.6]). In the descriptive study answers to the question whether patients were interested in being discharged on the day of surgery, were: “Yes” = 41%, “Do not know” = 20%, “No” = 39%. Patients responding “No” had lower preoperative PROM-scores, were older (“No” = 70.2 y vs. “Yes” = 65.3 y), and more often female (“No” = 72% vs. “Yes” = 52% female). Based on
COVID-19 confers a three-fold increased mortality risk among hip fracture patients. The aims were to investigate whether vaccination was associated with: i) lower mortality risk, and ii) lower likelihood of contracting COVID-19 within 30 days of fracture. This
Aims. Slipped capital femoral epiphysis (SCFE) is one of the most common hip diseases of adolescence that can cause marked disability, yet there is little robust evidence to guide treatment. Fundamental aspects of the disease, such as frequency, are unknown and consequently the desire of clinicians to undertake robust intervention studies is somewhat prohibited by a lack of fundamental knowledge. Methods. The study is an anonymized

Aims. Joint arthroplasties may be associated with a blood loss, which necessitates transfusion. Especially, hip arthroplasties are highly associate with transfusion to compensate perioperative bleeding. Orthopaedic surgeons and patients have increasing concerns regarding complications of blood transfusions. Although various methods to reduce transfusions have been attempted in TJA, a high percentage of patients require a transfusion during and after the procedures. The purposes of this study were to evaluate the trends of the transfusion(transfusion rates, transfusion amounts, economic burden) in hip arthroplasties, using

The aim was to determine the influence of COVID-19 on 30-day mortality in hip fracture. Secondary aims were to examine: (1) predictors of COVID-19 on presentation and later in the admission; (2) rate of hospital-acquired COVID-19; (3) predictive value of negative swabs on admission. A
The aim of this study was to examine perioperative blood transfusion practice, and associations with clinical outcomes, in a national cohort of hip fracture patients. A retrospective cohort study was undertaken using linked data from the Scottish Hip Fracture Audit and the Scottish National Blood Transfusion Service between May 2016 and December 2020. All patients aged ≥ 50 years admitted to a Scottish hospital with a hip fracture were included. Assessment of the factors independently associated with red blood cell transfusion (RBCT) during admission was performed, alongside determination of the association between RBCT and hip fracture outcomes.Aims

Although the clinical manifestation of ONFH is well summarized as forms of various stages, its etiology, natural history or epidemiology has not been clearly elucidated yet. With this study, we wanted to find out the estimated annual incidence, epidemiologic characteristics and the effect of known risk factors of ONFH. Therefore we can understand the disease better to provide optimal management to the patients. Among 133 189 patients who diagnosed as osteonecrosis of femoral head (ONFH) in database of national health insurance system in Korea from 2002 to 2006, three hundreds an eighty-two samples were randomly extracted with 5% error range in 95% confidence interval. With a structured worksheet, medical records and radiographs of each sample were reviewed at corresponding clinic or hospital by authors and trained orthopedic surgeons. With these data, we calculated the prevalence and associated risk factors. The mean number of annual requests was 23 466. Among 382 samples, two hundreds and seventy-four were confirmed to have ONFH. Diagnostic accuracy was 71.7 %. Diagnosis was more accurate when the patient was male or hospitalized. After the logistic regression analysis, calculated diagnostic accuracy during 2002 and 2006 was 60.3% (51 823/85 987). The annual predicted number of cases of ONFH during this period was 14 103. It corresponds to 28.91 patients per 100 000 populations. Alcohol abuse was noted in 45% and 22% was related to use of steroid. 37% showed bilateral involvement. Bone graft procedures in any kind was the most frequently performed joint preserving procedure. With this, the first epidemiologic study for ONFH in Korea, we estimated

Purpose:. To investigate treatment patterns and efficacy of postoperative strong opioids in patients who underwent total knee arthroplasty (TKA) in Korea. Methods:. A prospective, non-interventional study of 301 patients who underwent TKA and received strong opioids following patient controlled analgesia (PCA) was conducted by reviewing patient charts and diaries from 19 teaching hospitals. Clinical characteristics, strong opioid treatment patterns, efficacy of strong opioid on a scale of 0–10, and opioid-related adverse events (AEs) were investigated during hospitalization and at first outpatient visit. Safety analysis was conducted on 301 patients, and efficacy analysis was conducted on full analysis set (FAS) which consisted of all the patients who had at least 1 efficacy result among 301 patients. Results:. Among the FAS population of 298 patients, 86.9% were female, and mean age was 68.7 ± 7.5 years. Average duration of PCA was 4.3 ± 1.7 days, and average length of hospital stay including surgery was 16.3 ± 7.6 days. The mean duration of strong opioid prescription on a regular basis between PCA discontinuation and discharge was 10.3 ± 6.7 days. At the initial treatment with strong opioid following PCA, mean pain intensity score was 6.1 ± 2.1 upon movement and 4.2 ± 2.4 at rest. At discharge, mean pain intensity score was 4.1 ± 1.9 upon movement and 2.3 ± 1.8 at rest. Meanwhile, pain intensity score at the first outpatient visit was assessed only in 146 patients (49.0%) treated with opioid, and mean pain intensity scores upon movement and at rest were 3.5 ± 2.1 and 1.7 ± 1.8, respectively. Most frequently prescribed opioid was oral oxycodone (47.4%), followed by pethidine injection (17.2%), oral oxycodone/naloxone (12.6%), and transdermal fentanyl (12.0%). Additionally, the most frequently prescribed opioid on a regular basis was oral oxycodone (53.3%), and that on a PRN (pro re nata) basis was pethidine injection (48.4%). Among treatments, mean duration and mean daily dose of oral oxycodone during hospitalization were 6.1 ± 5.6 days and 13.9 ± 8.2 mg, 1.6 ± 1.2 days and 45.5 ± 24.5 mg for pethidine injection, 7.3 ± 5.3 days and 16.2 ± 7.3 mcg/hr for transdermal fentanyl, and 9.4 ± 8.0 days and 23.2 ± 16.8 mg/11.6 ± 8.34 mg for oral oxycodone/naloxone. At discharge, 150 patients (50.3%) were prescribed opioids. The most frequently prescribed strong opioid as discharge medications and their mean daily dose were 17.9 ± 10.5 mg of oxycodone (56.6%), 26.8 ± 17.0 mg/13.4 ± 8.5 mg of oxycodone/naloxone (17.1%), and 15.9 ± 6.1 mcg/hr of fentanyl (11.4%). Of 301 patients, 36 opioid-related AEs were reported in 26 patients (8.6%); the most frequently reported opioid-related AEs were nausea/vomiting in 13 patients (4.3%) experiencing 17 events, constipation in 10 patients (3.3%) experiencing 10 events, and sedation in 3 patients (1.0%) experiencing 3 events. Conclusion:. The first
Aims: In 1999 we published a cohort of 24,638 polyethylene-on-metal total hip arthroplasty (THA) patients followed up for cancer, using Finnish Cancer Registry data, from 1980 to 1995. The number of person-years was then 173,022 (until 31st Dec, 1996). During follow-up, there were statistically significantly fewer cancers among the THA patients (standardized incidence ratio [SIR], 0.91; 95% confidence interval [Cl], 0.87–0.94). There was no significantly increased risk at any site, and for certain cancers that was even below the unity (lung and stomach). On the longer run, however, certain tendency for increased risk for cancer of the urinary bladder, myeloma, and leukemia could be observed; SIRs were greater than unity with the THA patients followed up 3 to 9 years. Further follow-up of the cohort is therefore needed. Methods: The follow-up of the same cohort, originally identified in the National Register of Arthroplasties, maintained by the National Agency for Medicines (primary THA with primary arthritis as the indication) was expanded with a four year period (from 1st of Jan 1997 to 31st of Dec 2000). Follow-up for cancer was undertaken using the files in the population-based,
The aim of this surgery was to determine current practice amongst orthopaedic surgeons in New Zealand with regard to Anterior Cruciate Ligament Reconstruction. All current members of the NZOA were sent a questionnaire on the numbers and proportions of grafts performed, methods of fixation, operative technique and return to sport. One hundred and ten of 140 questionnaires were returned completed. Ninety two orthopaedic surgeons were performing ACL reconstructions. Eight per cent performed patellar tendon grafts in preference to hamstring grafts, whereas 16% preferred hamstring over patellar tendon grafts. Almost 2000 patellar tendon grafts at an average of just over 20 per surgeon are performed each year compared to just over 500 hamstring grafts at an average of just over 15 per surgeon. Metal interference screws were the most common fixation device in patellar tendon and hamstring grafts. Patellar tendon grafts are the most common grafts used for ACL reconstruction with 80 % of those surveyed preferring to use patellar tendon over hamstring grafts. Metal interference screws were the most common fixation device. There is reasonable consensus regarding return to activity and sport.
The purpose of this study was to evaluate the effect of common medical comorbidities on the reimbursements of different shoulder arthroplasty procedures We conducted a retrospective query of a private payer insurance claims database of prospectively collected data (PealDiver). Our search included the Current Procedural Terminology Codes (CPT) and International Classification of Disease (ICD) ninth edition codes for Total Shoulder Arthroplasty (TSA), Hemiarthroplasty (HA) and Reverse Shoulder Arthroplasty (RSA). Medical comorbidities were also searched for through ICD codes. The comorbidities selected for analysis were obesity, morbid obesity, hypertension, smoking, diabetes mellitus, hyperlipidemia, atrial fibrillation, chronic obstructive pulmonary disease (COPD), cirrhosis, depression and chronic kidney disease (CKD) (excluding end stage renal disease). The study period comprised claims from 2010 to 2014. The reimbursement charges of the day of surgery, 90-day global period and 90-day period excluding the initial surgical day of each comorbidity were analyzed and compared. Statistical analysis was conducted trough analysis of variance (ANOVA) when the data was normally distributed or through Kruskal-Wallis comparison when it was not. An alpha value of less than 0.05 was deemed as significant.Purpose
Methods
Periprosthetic infection is the most challenging complication following total knee arthroplasty (TKA). Poor oral hygiene has been assumed as an important risk factor for TKA infection. We aimed to investigate whether the improvement of oral hygiene through dental scaling could reduce the risk of TKA infection. A nested case control study was conducted and enrollees in the National Health Insurance Research Database (NHIRD) aged above 40 years who had received total knee arthroplasty (TKA) between 1999–2002 were included as the TKA cohort. The cases were patients who underwent resection arthroplasty for infected TKA, and each case was matched by 4 controls from the TKA cohort by gender, using incidence density sampling method. The frequency of dental scaling before the index date was analyzed and compared between the case and the control groups. Multiple conditional logistic regression was used to assess the frequency of dental scaling and the risk of TKA infection.BACKGROUND
METHODS
The aim of this study was to determine if patient reported outcome scores for arthroscopic meniscectomy are adversely affected by the degree of knee osteoarthritis or patient body mass index (BMI). All patients who underwent arthroscopic meniscectomy within the NHS in Scotland between 6th February and 29th April 2012 were audited as part of the Scottish Government Musculoskeletal Knee Arthroscopy Audit and were eligible for inclusion within this study. A total of 270 patients returned both their pre-operative and post-operative EuroQol 5Q5D5L descriptive questionnaire and Knee injury and Osteoarthritis Outcomes Scores. Patients were stratified according to BMI, degree of osteoarthritis, history of injury, and duration of knee symptoms. Pre-operative to post-operative EuroQol index scores [0.642±0.253 to 0.735±0.277, median±SD] and Knee injury and Osteoarthrtis Outcome Scores [44.63±18.78 to 62.28±24.94, median±SD] improved across all patients (p<0.0001). This was irrespective of degree of BMI, history of injury, or duration of symptoms. There was no such improvement in patients with moderate to severe osteoarthritis. Those patients with a BMI >35 kg/m2 had lower post-operative scores than the pre-operative scores of those of BMI <30 kg/m2. Arthroscopic meniscectomy is beneficial regardless of patient BMI, duration of symptoms, history of injury, or in the presence of mild arthritis.
Level 1 studies for fracture management of upper extremity fractures remains rare. The influence of these studies on management trends has yet to be evaluated. The purpose of this study was to examine alterations in national trends managing mid-shaft clavicle and intra-articular distal humerus fractures (DHF) surrounding recent Level 1 publications. We retrospectively reviewed a comprehensive Medicare (2005–2012) and Humana (2007–2014) patient population database within the PearlDiver supercomputer (Warsaw, IN, USA) for DHF and mid-shaft clavicle fractures, respectively. Non-operative management and open reduction internal fixation (ORIF) were reviewed for mid-shaft clavicle fractures. ORIF and total elbow arthroplasty (TEA) were reviewed for DHF. Total use and annual utilization rates were investigated using age limits defined in the original Level 1 studies.Background

Aims. Is it feasible to conduct a definitive multicentre trial in community settings of corticosteroid injections (CSI) and hydrodilation (HD) compared to CSI for patients with frozen shoulder? An adequately powered definitive randomized controlled trial (RCT) delivered in primary care will inform clinicians and the public whether hydrodilation is a clinically and cost-effective intervention. In this study, prior to a full RCT, we propose a feasibility trial to evaluate recruitment and retention by patient and clinician willingness of randomization; rates of withdrawal, crossover and attrition; and feasibility of outcome data collection from routine primary and secondary care data. Methods. In the UK, the National Institute for Health and Care Excellence (NICE) advises that prompt early management of frozen shoulder is initiated in primary care settings with analgesia, physiotherapy, and joint injections; most people can be managed without an operation. Currently, there is variation in the type of joint injection: 1) CSI, thought to reduce the inflammation of the capsule reducing pain; and 2) HD, where a small volume of fluid is injected into the shoulder joint along with the steroid, aiming to stretch the capsule of the shoulder to improve pain, but also allowing greater movement.

Introduction. Individuals with significant hip and knee trauma receive total knee (TKA) and total hip arthroplasty (THA) as definitive end-stage procedures. In Aotearoa, injury-related costs, including workers compensation, may be funded by ACC. With a steady increase of arthroplasty procedures in Aotearoa, we aim to understand the magnitude and characteristics of such procedures to inform future healthcare strategies. Method. This is a longitudinal collaborative study from 1st January 2000 to 31st December 2020, using ACC and New Zealand Joint Registry databases. Total cost was subcategorised into social and medical cost for analysis. Results. ACC funded 10179 TKA and 5611 THA, amounting to 918 million New Zealand Dollars. Most clients were between 55 and 65 years of age at time of surgery, with greater representation by Male sex and European prioritised ethnicity. Māori and Pacific peoples represent less than 10% of the study population. ACC identified requiring more than 182 days of workers’ compensation as a significant marker for needing additional supports. Risk of this was 21% for TKA and 11% for THA, with risk factors being younger age (RR 0.96), Male sex (TKA RR 1.12, THA RR 1.23), and heavy work-types (TKA RR 1.50, THA RR 1.57). Discussion. Supporting individuals with post-traumatic lower limb arthroplasty is costly. Workers’ compensation contributes to a significant proportion of social expenditure. Risk factors for increased cost utilisation can be used to highlight vulnerable clients and target interventions. Conclusions. This is one of few

Aims. It has been suggested that cemented fixation of total hip arthroplasty
(THA) is associated with an increased peri-operative mortality compared
with cementless THA. Our aim was to investigate this through a nationwide
matched cohort study adjusting for age, comorbidity, and socioeconomic
background. Patients and Methods. A total of 178 784 patients with osteoarthritis who underwent
either cemented or cementless THA from the Swedish Hip Arthroplasty
Register were matched with 862 294 controls from the general population.
Information about the causes of death, comorbidities, and socioeconomic
background was obtained. Mortality within the first 90 days after
the operation was the primary outcome measure. Results. Patients who underwent cemented THA had an increased risk of
death during the first 14 days compared with the controls (hazard
ratio (HR) 1.3, confidence interval (CI) 1.11 to 1.44), corresponding
to an absolute increase in risk of five deaths per 10 000 observations.
No such early increase of risk was seen in those who underwent cementless THA.
Between days 15 and 29 the risk of mortality was decreased for those
with cemented THA (HR 0.7, CI 0.62 to 0.87). Between days 30 and
90 all patients undergoing THA, irrespective of the mode of fixation,
had a lower risk of death than controls. Patients selected for cementless
fixation were younger, healthier and had a higher level of education
and income than those selected for cemented THA. A supplementary
analysis of 16 556 hybrid THAs indicated that cementation of the
femoral component was associated with a slight increase in mortality
up to 15 days, whereas no such increase in mortality was seen in
those with a cemented acetabular component combined with a cementless
femoral component. Conclusion. This

As a centre that carries out a high volume of unicompartmental knee arthroplasty (UKA), our objectives were: 1) to determine whether the PROMs programme included primary UKA when calculating the gain in Oxford Knee Score (OKS); and 2) to determine the impact of excluding primary UKA on calculated OKS gains for primary knee arthroplasty. Materials and Methods. National PROMs data from England (2012 to 2016) were analyzed. Inclusion of UKA cases in the national PROMs programme was determined using clinical codes. Local OKS gain was calculated for UKA and TKA and compared with the published PROMs results for 2012/13. Results. Use of the recommended codes for primary UKA excluded 99.6% of UKAs locally and 97% nationally from PROMs programme analysis. Inclusion of primary UKAs in PROMs analysis improved our OKS gain from 15.1 (below average) to 16.3 (above average) for 2012/13 for primary knee arthroplasty. Conclusion. Exclusion of UKA patients from the PROMs programme is a
The aim of this study was to report the procedure survival and patient-reported outcomes in a consecutive series of patients <50yrs at the time of hip arthroplasty with a metal-on-metal hip resurfacing system who have progressed to a minimum of 10yrs follow-up. Patients presenting for treatment of degenerative conditions of the hip electing to undergo hip resurfacing were included in a clinical registry (N=226 patients; 238 procedures). Procedure survival was confirmed by crosschecking to the Australian Orthopaedic Association National Joint Replacement Registry and comparing to all procedures by other surgeons
The optimal choice of management for proximal humerus fractures (PHFs) has been increasingly discussed in the literature, and this work aimed to answer the following questions: 1) what are the incidence rates of PHF in the geriatric population in the USA; 2) what is the mortality rate after PHF in the elderly population, specifically for distinct treatment procedures; and 3) what factors influence the mortality rate? PHFs occurring between 1 January 2009 and 31 December 2019 were identified from the Medicare physician service records. Incidence rates were determined, mortality rates were calculated, and semiparametric Cox regression was applied, incorporating 23 demographic, clinical, and socioeconomic covariates, to compare the mortality risk between treatments.Aims

Background. As the number of total knee arthroplasties (TKA) being performed continues to increase, the number of potential failures requiring revision surgery would also be expected to increase. This study analyzed the trends in revision TKA (rTKA) from 2009 to 2016. Methods. The
Purpose: Many strategies have been reported for decreasing the cost of orthopaedic procedures, including negotiating lower prices with manufacturers and using lower-cost generic implants, but prosthetic waste has not been investigated. The purpose of this study was to characterize the present and potential future cost of intra-operative waste of hip and knee implants. Method: A regional prospective assessment of implant waste was performed from January 2007 to June 2008, evaluating the incidence and reasons for component waste, the cost of the wasted implants, and where the cost was absorbed (hospital or manufacturer). Using published data on

Achilles tendon re-rupture (ATRR) poses a significant risk of postoperative complication, even after a successful initial surgical repair. This study aimed to identify risk factors associated with Achilles tendon re-rupture following operative fixation. This retrospective cohort study analyzed a total of 43,287 patients from national health claims data spanning 2008 to 2018, focusing on patients who underwent surgical treatment for primary Achilles tendon rupture. Short-term ATRR was defined as cases that required revision surgery occurring between six weeks and one year after the initial surgical repair, while omitting cases with simultaneous infection or skin necrosis. Variables such as age, sex, the presence of Achilles tendinopathy, and comorbidities were systematically collected for the analysis. We employed multivariate stepwise logistic regression to identify potential risk factors associated with short-term ATRR.Aims

Introduction. Total knee arthroplasty (TKA) is a successful treatment for degenerative end stage knee arthritis. Younger patients who undergo TKA may face multiple revisions during their lifetime due to aseptic loosening, infection, and instability. The purpose of this study was to compare the early complication rates and revision free survivorship between age groups undergoing TKA in a
Aim. Early discharge of patients after joint arthroplasty leaves patients responsible for monitoring their postoperative wound by themselves. This might result in a delayed presentation of postoperative complications. The use of a mobile woundcare app by patients after arthroplasty might result in (1) earlier report of complications, (2) an increase in patient satisfaction and (3) insight in the incidence and duration of postoperative wound leakage. Therefore, the ease of use and perceived usefulness of using a postoperative mobile woundcare app in patients after joint arthroplasty was investigated. Method. A cohort study was conducted in 2017 in 2 Dutch Hospitals. Eligible cases were all consecutive patients that received an arthroplasty and who owned a smartphone. During the first 30 postoperative days, patients filled in daily reviews of their wound and took a photo of the wound. Based on the review, an underlying algorithm calculated daily a score that prompted a mobile alert if needed, which advised patients to contact the hospital. Patients filled in a form on day 30 and day 90 in order to document occurrence of any postoperative wound complication. On day 15 and 30, patients were requested to fill in a questionnaire evaluating the perceived usefulness and the ease of use of the App. Results. Of 127 eligible patients, 30 (24%) did not have a smartphone. Of the remaining 97 patients, 69 patients (71%) were included. Median age was 68 years (range 33–90 years). Forty-one patients (59.4%) used the app until day 30. On average, the app was used for 19.1 days (95% CI 16.6–21.5). Nine patients (13.0%) stopped using the app directly after the first or second day. The overall mean grade on a scale of 1 (strongly disagree) to 5 (strongly agree) was 4.2 for ease of use and 4.1 for perceived usefulness. The scores on day 30 were comparable to day 15. One patient (1.4%) developed a prosthetic joint infection. Conclusions. The introduction of a mobile woundcare app resulted in a high overall satisfaction rate with respect to ease of use and perceived usefulness. Daily use of the app did not lead to more stress.

Introduction: Femoral shaft fractures are commonly thought to be primarily associated with high energy trauma in young persons. Only limited attention has be given to low energy violence as a cause of these fractures among the elderly. National epidemiological data on characteristics of patients with femoral shaft fractures are lacking. So the purpose of this study was to analyse the incidence, admissions, causes of fracture and operations for these fractures on a
Data of high quality are critical for the meaningful interpretation of registry information. The National Joint Registry (NJR) was established in 2002 as the result of an unexpectedly high failure rate of a cemented total hip arthroplasty. The NJR began data collection in 2003. In this study we report on the outcomes following the establishment of a formal data quality (DQ) audit process within the NJR, within which each patient episode entry is validated against the hospital unit’s Patient Administration System and vice-versa. This process enables bidirectional validation of every NJR entry and retrospective correction of any errors in the dataset. In 2014/15 baseline average compliance was 92.6% and this increased year-on-year with repeated audit cycles to 96.0% in 2018/19, with 76.4% of units achieving > 95% compliance. Following the closure of the audit cycle, an overall compliance rate of 97.9% was achieved for the 2018/19 period. An automated system was initiated in 2018 to reduce administrative burden and to integrate the DQ process into standard workflows. Our processes and quality improvement results demonstrate that DQ may be implemented successfully at national level, while minimizing the burden on hospitals. Cite this article:
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. 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

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. 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

Patients with proximal femoral fractures (PFFs) are often multimorbid, thus unplanned readmissions following surgery are common. We therefore aimed to analyze 30-day and one-year readmission rates, reasons for, and factors associated with, readmission risk in a cohort of patients with surgically treated PFFs across Austria. Data from 11,270 patients with PFFs, treated surgically (osteosyntheses, n = 6,435; endoprostheses, n = 4,835) at Austrian hospitals within a one-year period (January to December 2021) was retrieved from the Leistungsorientierte Krankenanstaltenfinanzierung (Achievement-Oriented Hospital Financing). The 30-day and one-year readmission rates were reported. Readmission risk for any complication, as well as general medicine-, internal medicine-, and surgery/injury-associated complications, and factors associated with readmissions, were investigated.Aims

The presence of obesity has negative influence on the progress of osteoarthritis and increases the risk of undergoing a primary THA at an earlier age. However, the correlation of BMI and the risk for postoperative complications, revision surgery and infection rate is still controversial. In the largest cohort to this date, we used the German insurance claims database to evaluate the correlation of BMI and the risk of postoperative complications, mortality and revision rates following primary THA.

Pneumatic tourniquets are often used during the surgical treatment of unstable traumatic ankle fractures. The aim of this study was to assess the risk of reoperation after open reduction and internal fixation of ankle fractures with and without the use of pneumatic tourniquets. This was a population-based cohort study using data from the Danish Fracture Database with a follow-up period of 24 months. Data were linked to the Danish National Patient Registry to ensure complete information regarding reoperations due to complications, which were divided into major and minor. The relative risk of reoperations for the tourniquet group compared with the non-tourniquet group was estimated using Cox proportional hazards modelling.Aims

Several different designs of hemiarthroplasty are used to treat intracapsular fractures of the proximal femur, with large variations in costs. No clinical benefit of modular over monoblock designs has been reported in the literature. Long-term data are lacking. The aim of this study was to report the ten-year implant survival of commonly used designs of hemiarthroplasty. Patients recorded by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) between 1 September 1999 and 31 December 2020 who underwent hemiarthroplasty for the treatment of a hip fracture with the following implants were included: a cemented monoblock Exeter Trauma Stem (ETS), cemented Exeter V40 with a bipolar head, a monoblock Thompsons prosthesis (Cobalt/Chromium or Titanium), and an Exeter V40 with a Unitrax head. Overall and age-defined cumulative revision rates were compared over the ten years following surgery.Aims

Background. Inpatient dislocation after total hip arthroplasty (THA) is considered a non-reimbursable “never event” by the Centers for Medicare and Medicaid Services. There is extensive evidence that technical procedural factors affect dislocation risk, but less is known about the influence of non-technical factors. We evaluated inpatient dislocation trends following elective primary THA, and identified patient and hospital characteristics associated with the occurrence of dislocation. Methods. We used discharge records from the
