Total knee arthroplasty (TKA) is a cost effective
and extremely successful operation. As longevity increases, the demand
for primary TKA will continue to rise. The success and survivorship
of TKAs are dependent on the demographics of the patient, surgical
technique and implant-related factors. . Currently the risk of failure of a TKA requiring revision surgery
ten years post-operatively is 5%. . The most common indications for revision include aseptic loosening
(29.8%), infection (14.8%), and pain (9.5%). Revision surgery poses
considerable clinical burdens on patients and financial burdens
on healthcare systems. . We present a current concepts review on the
This observational cross-sectional study aimed to answer the following questions: 1) how has nonunion incidence developed from 2009 to 2019 in a nationwide cohort; 2) what is the age and sex distribution of nonunions for distinct anatomical nonunion localizations; and 3) how high were the costs for surgical nonunion treatment in a level 1 trauma centre in Germany? Data consisting of annual International Classification of Diseases (ICD)-10 diagnosis codes from German medical institutions from 2009 to 2019, provided by the Federal Statistical Office of Germany (Destatis), were analyzed. Nonunion incidence was calculated for anatomical localization, sex, and age groups. Incidence rate ratios (IRRs) were determined and compared with a two-sample z-test. Diagnosis-related group (DRG)-reimbursement and length of hospital stay were retrospectively retrieved for each anatomical localization, considering 210 patients.Aims
Methods
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

The aims of this study were to establish the incidence of acute
Achilles tendon rupture (AATR) in a North American population, to
select demographic subgroups and to examine trends in the management
of this injury in the province of Ontario, Canada. Patients ≥ 18 years of age who presented with an AATR to an emergency
department in Ontario, Canada between 1 January 2003 and 31 December
2013 were identified using administrative databases. The overall
and annual incidence density rate (IDR) of AATR were calculated
for all demographic subgroups. The annual rate of surgical repair
was also calculated and compared between demographic subgroups.Aims
Patients and Methods
Total knee arthroplasty (TKA) and total hip arthroplasty
(THA) are recognised and proven interventions for patients with
advanced arthritis. Studies to date have demonstrated a steady increase
in the requirement for primary and revision procedures. Projected
estimates made for the United States show that by 2030 the demand
for primary TKA will grow by 673% and for revision TKA by 601% from
the level in 2005. For THA the projected estimates are 174% and
137% for primary and revision surgery, respectively. The purpose
of this study was to see if those predictions were similar for England
and Wales using data from the National Joint Registry and the Office
of National Statistics. Analysis of data for England and Wales suggest that by 2030,
the volume of primary and revision TKAs will have increased by 117%
and 332%, respectively between 2012 and 2030. The data for the United
States translates to a 306% cumulative rate of increase between
2012 and 2030 for revision surgery, which is similar to our predictions
for England and Wales. The predictions from the United States for primary TKA were similar
to our upper limit projections. For THA, we predicted an increase
of 134% and 31% for primary and revision hip surgery, respectively. Our model has limitations, however, it highlights the economic
burden of arthroplasty in the future in England and Wales as a real
and unaddressed problem. This will have significant implications
for the provision of health care and the management of orthopaedic
services in the future. Cite this article:

Aim. Currently, gram-negative bacteria (GNB), including multidrug-resistant (MDR-GNB) pathogens, are gaining importance in the aetiology of prosthetic joint infection (PJI). To characterize the antimicrobial resistance patterns of Gram-negative bacteria (GNB) causing hip prosthetic joint infections in elderly patients treated at a Brazilian tertiary academic hospital. Method. This is a retrospective, cross-sectional study of patients over 60 years of age undergoing hip arthroplasty from 2018 to 2023 at a tertiary academic trauma, which were diagnosed with hip prosthetic joint infection. PJI diagnosed was based on EBJIS criteria, in which intraoperative tissue cultures identified the pathogens. Demographics, reason for arthroplasty, type of implant and susceptibility patterns using disk diffusion method were analysed. Results. Overall, among 17 elderly patients diagnosed with hip infected arthroplasty, 45 bacterial isolated were identified. Debridement, irrigation, antibiotic and implant retention (DAIR) procedures due to uncontrolled infection occurred in 47.0% (n=8/17), and five patients underwent more than two DAIR surgeries. Tissue cultures yielded eleven different bacterial species, with GNB accounted for 64.4% (n=29/45) of pathogens. Klebsiella pneumoniae, Acinetobacter baumannii, Escherichia coli, and Pseudomonas aeruginosa were identified in 34.5% (n=10/29), 17.25% (n=5/29), 13.8% (n=4/29), and 13.8% (n=4/29), respectively. In the resistance profile analysis, E. coli was most sensitive to antibiotics, whereas K. pneumoniae showed resistance rates higher than 70% for cephalosporins, carbapenems, and quinolones. All A. baumannii isolates were resistant to meropenem, and 80% of these isolates were resistant to amikacin. Conclusions. This study emphasizes the role of GNB in the microbiological profile of PJI among elderly patients at a tertiary hospital in a Brazilian centre. The present study portrays a worryingly higher rates of MDR-GNB, mainly to quinolones and cephalosporins resistance which have been the cornerstone of PJI antibiotic treatment. In addition, higher rates carbapenems and aminoglycosides resistance shows a threat to antibiotic treatment of PJI. More global studies need to be carried out to show a likely change in the microbial

Aims. Fractures of the distal radius are common, and form a considerable proportion of the trauma workload. We conducted a study to examine the patterns of injury and treatment for adult patients presenting with distal radius fractures to a major trauma centre serving an urban population. Methods. We undertook a retrospective cohort study to identify all patients treated at our major trauma centre for a distal radius fracture between 1 June 2018 and 1 May 2021. We reviewed the medical records and imaging for each patient to examine patterns of injury and treatment. We undertook a binomial logistic regression to produce a predictive model for operative fixation or inpatient admission. Results. Overall, 571 fractures of the distal radius were treated at our centre during the study period. A total of 146 (26%) patients required an inpatient admission, and 385 surgical procedures for fractures of the distal radius were recorded between June 2018 and May 2021. The most common mechanism of injury was a fall from a height of one metre or less. Of the total fractures, 59% (n = 337) were treated nonoperatively, and of those patients treated with surgery, locked anterior-plate fixation was the preferred technique (79%; n = 180). Conclusion.

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 Nationwide (OPEN) study, and report the demographic details and the initial steps of care for patients admitted with open fractures in the UK. Methods. Any patient admitted to hospital with an open fracture between 1 June 2021 and 30 September 2021 was included, excluding phalanges and isolated hand injuries. Institutional information governance approval was obtained at the lead site and all data entered using Research Electronic Data Capture. Demographic details, injury, fracture classification, and patient dispersal were detailed. Results. In total, 1,175 patients (median age 47 years (interquartile range (IQR) 29 to 65), 61.0% male (n = 717)) were admitted across 51 sites. A total of 546 patients (47.1%) were employed, 5.4% (n = 63) were diabetic, and 28.8% (n = 335) were smokers. In total, 29.0% of patients (n = 341) had more than one injury and 4.8% (n = 56) had two or more open fractures, while 51.3% of fractures (n = 637) occurred in the lower leg. Fractures sustained in vehicle incidents and collisions are common (38.8%; n = 455) and typically seen in younger patients. A simple fall (35.0%; n = 410) is common in older people. Overall, 69.8% (n = 786) of patients were admitted directly to an orthoplastic centre, 23.0% (n = 259) were transferred to an orthoplastic centre after initial management elsewhere, and 7.2% were managed outwith specialist units (n = 81).

Knee arthroscopy with debridement is commonly performed to treat osteoarthritis and degenerative meniscal tears in older adults; however robust evidence does not support sustained benefit from this procedure. Current Canadian guidelines advise against its use as first line treatment. Characterizing the use of this low value procedure will facilitate efforts to maximize quality of care, minimize harm and decrease healthcare costs. We sought to understand: the volume and variations of arthroscopic knee debridement across Canada The costs associated with potentially unnecessary arthroscopy The characteristics of surgeons performing knee arthroscopy in older adults Data were derived from National Ambulatory Care Reporting System (NACRS), the Discharge Abstract Database (DAD) and the National Physician Database for years 2011-12 to 2019-20. The study included all elective knee arthroscopies (CCI codes 1.VG.80.DA,1.VG.80.FY and 1.VG.87.DA) performed in day surgery and acute care settings in 9 provinces and 3 territories of Canada. Quebec was not included in the analysis due to different reporting methods. We set a threshold of 60 years of age at which it would be highly unlikely that a patient would undergo arthroscopy to treat anything other than osteoarthritis or degenerative meniscal tear. Trends at national and provincial levels were analyzed using regression. Costs were estimated separately using the 2020 case mix groups (CMG) and comprehensive ambulatory care classification system (CACS) methodologies. Surgeons were classified by decade of graduation from medical school (1989 and prior, 1990-99, 2000-09 and 2010+) and categorized based on the proportion of their patient population who were above (“high proportion inappropriate”) or below (“low proportion inappropriate”) the overall national proportion of ≥ 60 years of age. The number of knee arthroscopies decreased by 37% (42,785 in 2011-12 to 27,034 in 2019-20) overall and 39% (11,103 in 2011-12 to 6,772 in 2019-20) in those 60 years and older (p 25% of patients 60 years and older. Fifty four percent of surgeons who graduated prior to 1989 were considered high proportion inappropriate, whereas only 30.1% of surgeons who graduated in 2010 or later were considered high proportion inappropriate (p < 0 .0001). Knee arthroscopy continues to be a common procedure in patients over 60 despite strong evidence for lack of benefit. Lower rates in this population in some provinces are encouraging for potential opportunity for improvement. Efforts at practice change should be targeted at surgeons in practice the longest. Canada spends over $12,000,000 per year on this procedure, decreasing its use could allow these resources to be directed to other areas of orthopaedics that provide higher value care.

A number of studies have described the epidemiological characteristics of clavicle fractures, including two previous reports from our institution. The Robinson classification system was described in 1998, after the analysis of 1,000 clavicle fractures. We aim to provide a contemporary analysis and compare current clavicle fracture patterns of our adult population with historical reports. A retrospective analysis of a prospectively collected fracture database from an institution serving 598,000 was conducted. Demographic data were recorded prospectively for each patient with an acute clavicle fractures including age, gender, mode of injury, fracture classification, and the presence of associated skeletal injuries. Fractures were classified according to the Robinson system. A total of 312 clavicle fractures were identified, occurring with an incidence of 55.9/100,000/yr (CI 49.8–62.5) and following a bimodal male and unimodal older female distribution. Sporting activity and a simple fall from standing caused the majority of injuries. More than half of simple fall fractures affected the lateral clavicle. The incidence of clavicle fractures has risen over a twenty year period, and a greater proportion of older adults are now affected. Overall, type II midshaft fractures remain the most common, but comparison of this series with historical data reveals that the

We aim to provide a contemporary analysis and compare current clavicle fracture patterns of our adult population with historical reports. Methods. A retrospective analysis of a prospectively collected fracture database from an institution serving 598,000 was conducted over a 12 month period, beginning July 2007. Demographic data were recorded prospectively for each patient presenting with an acute clavicle fracture including age, gender, mode of injury, fracture classification, and the presence of associated skeletal injuries.

Aim. Bone and joint infections (BJI) are associated with a heavy morbidity and high health costs. Comorbidities, device associated infections and complicated journeys are associated with increased mortality, treatment failures and costs. For this reason, 24 referral centers (RC) have been created in 2009 in order to advise about management of “complex” BJI in weekly multidisciplinary meetings (MM). Since end of 2012, data from these meetings are gathered in a national database. We aimed to describe the data from this French registry of BJI and determine factors associated with the definition of “complex” BJI. Method. Demographic, clinical, microbiologic and therapeutic characteristics of patients are systematically recorded in the database. Data from the first presentation in RC for each adult patients are presented. Complexity of BJI is recorded after each meeting according to 4 criteria (first failure, complex antibiotic therapy, precarious underlying conditions or complex surgical procedure). Part of unavailable data have been completed by pattern extraction from text-encoded commentaries. Factors associated with complexity were determined by multivariate logistic regression. Results. From 2012 to 2016, 17.527 patients were included corresponding to 30.300 presentations in MM. Median age was 64 years (IQR 50–76) with masculine predominance (61.8%). Comorbidity was present in 50.3%, with at least 2 comorbidities in 26%. Prosthetic joint infection represented 41.4% of patients, followed by chronic osteitis with/without foreign material (24%). Definite microbiologic documentation was available in 68.8% of cases, mostly Staphylococcus aureus (43.9%) followed by Coagulase negative Staphylococci (28.6%) and enterobacteriaceae (23.1%), with 27.4% of polybacterial infections. Antibiotic treatment was proposed in 81.6% and surgery in 70% of cases. BJI were defined as complex in 55.4%, mostly because underlying conditions (50%), and in 57.6% with at least 2 complexity criteria. Factors positively associated with definition of complexity in MM were: background: number of comorbidities, immunodeficiency, neoplasia, liver or kidney failure, intra-cardiac device; microbiology: Mycobacteria, Fungus, MRSA, MSSA, MR-CoNS, MDR enterobacteria, non-fermentative BGN, and atypical pathogens (actinomycetes, nocardia, intra-cellular …); infection characteristics: prosthetic joint infection, osteitis, foreign material infection, arthritis and number of infected sites; surgical procedures: surgical flap, 2 stages prosthesis exchange, spacer, arthrodesis, and joint removal. Simple debridement was negatively associated with complex definition. Conclusions.

Aims. This study aimed to describe the use of revision knee arthroplasty in Australia and examine changes in lifetime risk over a decade. Methods. De-identified individual-level data on all revision knee arthroplasties performed in Australia from 2007 to 2017 were obtained from the Australian Orthopaedic Association National Joint Replacement Registry. Population data and life tables were obtained from the Australian Bureau of Statistics. The lifetime risk of revision surgery was calculated for each year using a standardized formula. Separate calculations were undertaken for males and females. Results. In total, 43,188 revision knee arthroplasty procedures were performed in Australia during the study period, with a median age at surgery of 69 years (interquartile range (IQR) 62 to 76). In 2017, revision knee arthroplasty rates were highest for males aged 70 to 79 years (102.9 procedures per 100,000 population). Lifetime risk of revision knee arthroplasty for females increased slightly from 1.61% (95% confidence interval (CI) 1.53% to 1.69%) in 2007 to 2.22% (95% CI 2.13% to 2.31%) in 2017. A similar pattern was evident for males, with a lifetime risk of 1.43% (95% CI 1.36% to 1.51%) in 2007 and 2.02% (95% CI 1.93% to 2.11%) in 2017. A decline in procedures performed for loosening/lysis (from 41% in 2007 to 24% in 2017) and pain (from 14% to 9%) was evident, while infection became an increasingly common indication (from 19% in 2007 to 29% in 2017).

Epidemiological data about tibial plateau and associated intra-articular proximal tibial fractures provides clinicians with an understanding of the range, variety, and patterns of injury. There are relatively few studies examining this injury group as a whole. We prospectively recorded all tibial plateau and intra-articular proximal tibial fractures occurring in our regional population of 545,000 adults (aged 15 years or older) in 2007–2008. We then compared our results with previous research from our institution in 2000. There were 173 fractures around the knee, 65 of these involved the tibial plateau. Median age was 59 years (IQR, 36.5–77.5 yrs). Tibial plateau fractures were more common in women (58.5%vs 41.5%). The median age of men was 37 years (IQr, 29–52 yrs) compared to women, 73 years (IQR, 57–82 yrs). Tibial plateau fractures accounted for 0.9% overall and 2.5% of lower limb fractures. Incidence was 1.2/10,000/yr (95% CI, 0.9–1.5). We have prospectively identified and described the epidemiological characteristics of tibial plateau fractures in adults from our region.

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.

Rhabdomyosarcoma (RMS) is one of the typical tumors of childhood and adolescence, but it is exceedingly rare in adults. Unfortunately, the treatment success achieved over the years for pediatric RMS has not translated into better cure rates for adults, who continue to have a very poor prognosis (overall survival rates of only 20–40%). To better characterize adult RMS, we performed an analysis of all RMS cases registered on the Surveillance

Brazilian jiu-jitsu (BJJ) is a grappling-based martial art which can lead to injuries both in training and in competitions. There is a paucity of data regarding injuries sustained while training in Brazilian jiu-jitsu both in competitive and non-competitive jiu-jitsu athletes. Our primary objective was to determine the prevalence of injuries sustained during jiu-jitsu training and competition. Our secondary objectives were to describe the types of injuries, and to determine which participant and injury characteristics are associated with desire to discontinue jiu-jitsu following injury, and characteristics are associated with requiring surgery for an injury. We conducted a survey of all BJJ participants at one club in Hamilton Ontario. We developed a questionnaire using focus groups, key informants and the previous literature. The questionnaire included questions on demographics, injuries in competition and/or training, treatment received, and whether the participant considered discontinuing BJJ following injury. The primary analysis was descriptive. The secondary analysis consisted of unadjusted logistic regression analyses to evaluate the association between selected demographic and injury patterns and those who considered quitting jiu-jitsu as a result of their injuries as a dependent variable. Seventy BJJ athletes participated in this study (response rate 85%). The majority of respondents were male (90%), over the age of 30 years (58.6%), and junior trainees (white belts [37.2%] or blue belts [42.9%]). Ninety one percent of participants were injured in training and 60% of competitive athletes were injured in competitions. Significantly more injuries were sustained overall (p < 0 .001) for each body region (p∼0.001) in training in comparison to competition. Two-thirds of injured participants required medical attention, with 15% requiring surgery. Participants requiring surgical treatment were six and a half times more likely to consider quitting compared to those requiring other treatments, including no treatment (OR: 6.50, 95% CI: 1.53–27.60). Participants required to take more than four months off training were five and a half times more likely to consider quitting compared to those who took less time off (OR: 5.48, 95% CI: 2.25–13.38). We identified that nine out of ten jiu-jitsu practitioners surveyed suffered injury while in training and the most severe injuries for the majority of practitioners occurring during training. The most common injuries identified involved the fingers, neck, knee, and shoulder, with the majority of respondents seeking medical or surgical treatment or requiring physiotherapy or rehabilitation. Potential participants in BJJ should be informed regarding significant risk of injury and instructed regarding appropriate precautions and safety protocols. BJJ practitioners and instructors should be especially cognizant of safety during training, where the majority of injuries occur.
Synovial sarcoma (SS) is a typical soft tissue sarcoma subtype crosswise between the pediatric and the adult age groups. No published data describes a different biology of SS when arising in adults as opposed to children, but different therapeutic strategies have been developed for pediatric and adult oncology protocols dealing with SS (in particular concerning the use of systemic therapy) and different overall outcomes have been reported by pediatric and adult groups. To better characterize the clinical features and outcomes of SS across the different age groups, we performed an analysis of all SS cases registered on the Surveillance,
Little is known about the incidence of rotator
cuff pathology or its demographic associations in the general population.
We undertook a large epidemiological study of rotator cuff pathology
in the United Kingdom using The Health Improvement Network (THIN)
database. The incidence of rotator cuff pathology was 87 per 100
000 person-years. It was more common in women than in men (90 cases
per 100 000 person-years in women and 83 per 100 000 person-years
in men; p <
0.001). The highest incidence of 198 per 100 000
person-years was found in those aged between 55 and 59 years. The
regional distribution of incidence demonstrated an even spread across
13 UK health authorities except Wales, where the incidence was significantly
higher (122 per 100 000 person-years; p <
0.001). The lowest
socioeconomic group had the highest incidence (98 per 100 000 person-years).
The incidence has risen fourfold since 1987 and as of 2006 shows
no signs of plateauing. This study represents the largest general population study of
rotator cuff pathology reported to date. The results obtained provide

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.
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). 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.Aims
Methods
A relationship between social deprivation and the incidence of fracture in adolescents has not previously been shown. We have used a complete fracture database to identify adolescents who sustained fractures in 2000. The 2001 Scottish census was used to obtain age-specific population and deprivation data according to the Carstairs score. Regression analysis determined the relationship between the incidence of fractures and social deprivation. We analysed 1574 adolescents with fractures (1083 male, 491 female). The incidence of fractures in this group was 21.8 per thousand (31.0 male, 13.1 female). Social deprivation predicted the incidence in adolescent males and females. The incidence of fractures of the proximal upper limb and distal radius in females was overwhelmingly influenced by socioeconomic factors. Males of 15 to 20 years of age were more likely to sustain fractures of the hand and carpus if they lived in economically depressed neighbourhoods.
The Royal College of Surgeons of England (RCS) recently issued guidance regarding the use of re-operation rates in the re-validation of UK based orthopaedic surgeons. Currently, little has been published concerning acceptable rates of re-operation following primary surgical management of orthopaedic trauma, particularly with reference to re-validation. We conducted a retrospective review of patients undergoing a clearly defined re-operation following primary surgical management of trauma between 1st January 2010 and 31st December 2011. 3688 patients underwent primary procedures while 83 (2.25%; 99%CI = 1.69 to 2.96%) required an unplanned re-operation. The mean age of patients was 46 years (range 2–98) with 46 (55%) males and a median time to re-operation of 34 days (IQR 12–134). Potentially avoidable re-operations occurred in 47 patients (56.6%; 99%CI = 42.6 to 69.8%) largely due to technical errors (46 patients; 55.4%; 99%CI = 41.4 to 68.7%), representing 1.27% (99%CI = 0.87 to 1.83%) of the total trauma workload. Within RCS guidelines 28 day re-operation rates for hip fractures, wrist fractures and ankle fractures were 1.4% (99%CI = 0.5 to 3.3%), 3.5% (99%CI = 0.8% to 12.1%) and 2.48% (99%CI = 0.7 to 7.6%) respectively. We present novel work that has established baseline re-operation rates for index procedures required for revalidation of orthopaedic surgeons.
The aim of this study was to identify variables associated with time to revision, demographic details associated with revision indication, and type of prosthesis employed, and to describe the survival of hinge knee arthroplasty (HKA) when used for first-time knee revision surgery and factors that were associated with re-revision. Patient demographic details, BMI, American Society of Anesthesiologists (ASA) grade, indication for revision, surgical approach, surgeon grade, implant type (fixed and rotating), time of revision from primary implantation, and re-revision if undertaken were obtained from the National Joint Registry data for England, Wales, Northern Ireland, and the Isle of Man over an 18-year period (2003 to 2021).Aims

The accepted mechanism of traumatic limb amputation following blast is initial bone disruption due to the shock wave, with amputation completed by the blast wind; survival is considered unlikely. The high survival rate of traumatic amputees following explosion, from the current conflict in Afghanistan, is at odds with previous work. We reviewed extremity injuries, sustained in Afghanistan by UK military personnel, over a 2 year period. 774 British servicemen and women sustained AIS >1 injuries, 72.6% of whom survived. No significant difference was found in the survival rates following explosive blast or gunshot (p>0.05). 169 casualties (21.8%) sustained 263 lower limb and 74 upper limb traumatic amputations. Amputations were more common in the lower than the upper limbs and more common in the extremity proximal bone. Bilateral lower limb amputations were more common than a unilateral lower limb amputation. The majority (99%) of major amputations were sustained as a result of explosion. 46.3% (74) of those who sustained a major amputation following explosion survived. Rates of fatalities caused by explosion, or by small arms are not statistically different. Blast-mediated amputations are not universally fatal, and a significant number were through joint, calling into question previously proposed mechanisms.
2010 marked a century since Perthes' disease was first described, but the aetiology and mechanism remain unknown. Worldwide, the incidence of Perthes' disease varies widely, yet this may be through differences in study design, population denominators or case ascertainment. It is suggested that differential exposure to adverse socioeconomic circumstances may be a key precipitant, although this remains the subject of debate. This work draws on several epidemiological studies that have sought to develop the understanding of Perthes' disease by examining a case register from Merseyside, discharge data from Scotland and the world's largest community disease register. A systematic review was performed to ensure a robustness and homogeneity between published studies in order to allow meaningful comparisons. Studies were based on data from the Merseyside Perthes' Disease Register (1976–2008), the UK General Practice Research Database (GPRD, 1990–2008) and hospital discharge data for Scotland (2000–2009). Temporal trends and geographic patterns were analysed and the relationship to deprivation investigated. A systematic review of the published literature was used to explore international variations in incidence up to December 2010 focusing upon the influence of race and latitude. Analyses were conducted using Poisson regression.Introduction

Over the past three years, roughly 100,000 hip and knee replacements have been performed by the Brazilian Public Healthcare System. Prosthetic joint infection (PJI) is expected to range between 1% to 10% after primary and revisions joint arthroplasties, respectively. So far, there have been no published national PJI data which would be helpful at developing local preventive strategies and guide surgeons and clinicians. We aimed at We prospectively enrolled patients with PJI in a national cohort study among 12 hospitals from 6 different States to describe host, pathogens, diagnosis, surgery strategies adopted (according to the standard hospital-based guideline) and outcome after 1- and 2-years follow-up. PJI was defined using the IDSA criteria (Osmon D, et al. Clin Infect Dis. 2013). Patients were enrolled from July 2013 to December 2015.Aim
Method
The goals of this study were to define the risk factors, nature,
chronology, and treatment strategies adopted for periprosthetic
femoral fractures in 32 644 primary total hip arthroplasties (THAs). There were 564 intra-operative fractures (1.7%); 529 during uncemented
stem placement (3.0%) and 35 during cemented stem placement (0.23%).
Intra-operative fractures were more common in females and patients
over 65 years (p <
0.001). The majority occurred during placement
of the femoral component (60%), and involved the calcar (69%). There
were 557 post-operative fractures (20-year probability: 3.5%; 95%
confidence interval (CI) 3.2 to 3.9); 335 fractures after placement
of an uncemented stem (20-year probability: 7.7%; 95% CI 6.2 to
9.1) and 222 after placement of a cemented stem (20-year probability:
2.1%; 95% CI 1.8 to 2.5). The probability of a post-operative fracture
within 30 days after an uncemented stem was ten times higher than
a cemented stem. The most common post-operative fracture type was
a Vancouver AG (32%; n = 135), with 67% occurring after
a fall. In all, 36% (n = 152) were treated with revision arthroplasty. Aim and Methods
Results
This study estimated trends in incidence of open fractures and the adherence to clinical standards for open fracture care in England. Longitudinal data collected by the Trauma Audit and Research Network were used to identify 38,347 patients with open fractures, and a subgroup of 12,170 with severe open fractures of the tibia, between 2008 and 2019 in England. Incidence rates per 100,000 person-years and 95% confidence intervals were calculated. Clinical care was compared with the British Orthopaedic Association Standards for Trauma and National Major Trauma Centre audit standards.Aims

To analyse the bacteriological spectrum, identify most appropriate antibiotics for hand infections, and to characterize patterns and sites of hand infections. This information was collected against the background of a high prevalence of HIV infected patients and increasing antibiotic resistance. This was a prospective, cross-sectional, analytical study done on 66 patients presenting with hand infections at a public hospital from January to June 2009. A standardised treatment protocol was followed in managing these patients. Data was collected from each participant, and laboratory reports were followed up for the identity and antibiotic susceptibility of causative organisms. All patients were counselled for HIV status and consenting participants were tested.Purpose of study:
Description of methods:
Total hip replacement procedures provide a very effective treatment modality for a wide range of diseases and injures to joints. The annual number of primary and surgeries has been increasing. In Region Emilia Romagna, 4000000 inhabitants, 4587 total hip replacements (THA) were performed in 1997 and the number raised up to 5410 in 2002 ( + 18%). Emiarthoplasties were respectively 1914 and 2215 (+ 16%). Parallely number of revision raised from 550 to 938 (+71%). In 2003 incidence of primary THAs in Emilia-Romagna is 107/100.000 inhabitants, higher than mean national value (76/100000). Data of both primary and revision surgeries are collected by RIPO (Register for Orthopaedic Prosthetic Implantology) that started its activity in Rizzoli Institute on January 1990 and in Regione Emilia-Romagna on January 2000. The recording of data is done for each joint replacement operation and it consists on the identification of the patient, information about diagnosis or reason for re-operation, surgical approach, antibiotic and antithromboembolic prophylaxis, perioperative complications. Acetabular, femoral and head components are separately registered, on the basis of stickers with catalogue numbers provided by manufacturers with the implants. Fixation of the components is recorded as well. Among the purposes of the Register there are the identification of early prosthesis failures, the information of surgeons on the outcome of their patients, the creation of a benchmarking tool for consultants and the speedy identification of relevant patients if a particular prosthesis or a particular batch gives cause for concern. As for Scandinavian registers, revision is used as an end-point in the analyses. On this basis it is possible to calculate survival curves either aggregated or stratified. By Cox multivariate analysis it has been ascertained that risk factors in total hip arthroplasties are represented by sex (females have lower risk than males), by age (younger than 40 are more at risk than 40–70s, and older than 70 are less at risk than 40–70s) and by pathology (fracture, coxites and Paget diseases have higher risk than coxarthrosis). Basing on these data, survival analysis was normalized and the influence of articular coupling and fixation of the components on prosthesis outcome have been evaluated. It resulted that failures are more likely to occur when metal on metal, or metal on polyethylene or ceramic on polyethylene devices rather than ceramic on ceramic implants are implanted. Similarly cemented and hybrid THAs fail at higher rate than uncemented ones. All data are referred to a 11 years follow-up. At present time Kaplan Meier analysis indicates a survival rate of total hip arthroplasties performed at Istituto Rizzoli of nearly 90% at ten years follow-up (9717 primary implants, 435 failures). Main reasons for revisions are aseptic loosening of the cup (33%),aseptic loosening of both components (18%), aseptic loosening of the stem (17%), deep infection (7.9%),dislocation (7.6%),prosthesis fracture (3%) etc. Aseptic loosening represent, therefore, the most frequent cause for revision. Results obtained at Istituto Rizzoli fit in the benchmarking set by the British NICE (National Institute for Clinical Excellence) that states that the revision rate should be of 10% or less at 10 years. To improve these results attention should be pointed on new models: hip prosthesis technology is continually changing, with new designs and techniques being introduced. There is a need to strike a balance between using prostheses with published long-term performance data, and the need to develop and improve hip prosthesis. A solution to this problem could be to entrust reference clinical centers the evaluation of the effectiveness of any new prosthesis for at least three years, before opening free distribution in standard orthopaedic units,as suggested by NICE. Only models that reach the ‘entry benchmark’ in adequately sized, well conducted observational studies, can be implanted with a good safety. At present time it is unlikely that clinical evaluation data on long term effectiveness is required by Notified Body for ‘CE’ marking, unless new materials are involved in the manufacture. This happens despite the fact that even small changes to existing prostheses can have a significant impact on implant performance and revision rate. Other factors than the already discussed can influence the surgery outcome, and among these the volume of operations performed in the hospital, the ability of the surgeon and its confidence with the technique, the compliance of the patient. Only an overall view of the situation will allow to reach the goal of reduction of need for revision of total hip arthroplasties.
The objective was to compare susceptibility testing of all coagulase negative species (CNS) found in periprosthetic joint infections (PJI). We conducted a multicentre retrospective study in a same area from 2011 to 2014, including 215 CNS strains. Diagnosis of PJI was based on clinical, radiological and biological criteria. Microbiological criterion was at least 2 per-operative deep positive cultures with the same species of CNS. Identification and susceptibility testing were performed on automated Vitek2 (Biomérieux, France). PJI localizations were 54% knees, 39% hips, 7% other sites. CNS found in our study were by dicreasing order: S. epidermidis (SE) 60%, S. capitis 11%, S. lugdunensis (SL) 10%, S. caprae 5%, S. warneri (SW) 4%, S. hominis (SHo) 3%, S. haemolyticus (SHa) 3%. Fifty two percent of CNS strains were meticillin (oxacillin) resistant and 31%, 33%, 41%, 20% were also resistant to clindamycin (CLI), trimethoprim-sulfamethoxazole (SXT), ofloxacin (OFX), rifampicin (RMP) respectively. Regarding CNS species, meticillin resistance was detected for 70% SE, 71% SHo and 71% SHa. SE was the most resistant species, with 34% of the strains resistant to CLI, SXT, OFX and RMP simultaneously. Half of SE and SHa were resistant to the reference treatment levofloxacin+rifampicin. Thirteen percent of CNS were resistant to teicoplanin and only 1% to vancomycin. Susceptibility testing profiles are presented in table field. In our study, S. epidermidis was the main species found in PJI. Emerging species like S. lugdunensis or S. caprae were found, with more susceptible antibiotic profiles. The most active antibiotics in vitro were daptomycin, linezolid, vancomycin and teicoplanin.
Infection of the musculoskeletal (MSK) system is a dreaded complication that seems to be on the rise. Many factors, such as resistant bacteria or poor host factors, may influence such rise. This increase leads to greater resource consumption, especially due to antibiotic (ATB) prescription. Strategies must be created to detect patients at risk and prevent such infections. Hospital administrators should be made aware of the costs and impact of MSK infections in order to understand the need to prevent such complications. Therefore, our goal is to characterize the infected orthopaedic patient and evaluate the cost associated with ATB prescription in such cases. This is a retrospective and descriptive study, based on patient record analysis of all patients treated at our department, from January 2013 to March 2015. We identified 177 patients with a MSK infection and an isolated infectious agent. There was no predominance of either sex. Approximately 50% of patients were aged between 66 and 85 years old. Most frequent agents were MSSA (30,2%) and MRSA (21,8%), followed by Streptococcus species (8,9%) and Pseudomonas aeruginosas (7,1%). Although most patients were infected by a single agent, 18,6% had two or more causative agents isolated in cultures. Of those, 69,7% had either MSSA or MRSA as one of the isolated agents. Most commonly affected area was the hip (39,5%), followed by the knee (23,2%) and ankle (21,5%). Nearly all patients had had prior surgery, with arthroplasty and osteosynthesis as the most common procedures (52,4% and 33,3%, respectively). Infection related admission was responsible for a total of 6.116 hospital bed-days, with the majority of patients staying in hospital for up to 30 days (77,3%). Total cost of hospital ATB administration was 61.365,61€, with approximately 346,7€ spent in each patient. This corresponds to 42,6% of the total cost of medication during hospital stay (144.146,1€ of total cost, with 814,4€ per patient). The typical infected orthopaedic patient is aged 66 to 85 years old, was operated to his hip or knee, and either an arthroplasty or osteosynthesis was performed. Staphylococcus aureus remains the most common agent. MSK infections have significant costs associated with their treatment, and clinical departments should periodically re-evaluate discharged patients in order to understand what groups are at risk of developing such a complication. Only a correct identification of all these factors makes it possible to create a targeted preventive strategy, in order to reduce costs to the institution.
