Aims. The primary aim was to determine the influence of COVID-19 on 30-day mortality following hip fracture. Secondary aims were to determine predictors of COVID-19 status on presentation and later in the admission; the rate of hospital acquired COVID-19; and the predictive value of negative swabs on admission. Methods. A nationwide multicentre retrospective cohort study was conducted of all patients presenting with a hip fracture to 17 Scottish centres in March and April 2020. Demographics, presentation blood tests, COVID-19 status, Nottingham Hip Fracture Score, management, length of stay, and 30-day mortality were recorded. Results. In all, 78/833 (9.4%) patients were diagnosed with COVID-19. The 30-day survival of patients with COVID-19 was significantly lower than for those without (65.4% vs 91%; p < 0.001). Diagnosis of COVID-19 within seven days of admission (likely community acquired) was independently associated with male sex (odds ratio (OR) 2.34, p = 0.040, confidence interval (CI) 1.04 to 5.25) and symptoms of COVID-19 (OR 15.56, CI 6.61 to 36.60, p < 0.001). Diagnosis of COVID-19 made between seven and 30 days of admission to hospital (likely hospital acquired) was independently associated with male sex (OR 1.73, CI 1.05 to 2.87, p = 0.032), Nottingham Hip Fracture Score ≥ 7 (OR 1.91, CI 1.09 to 3.34, p = 0.024), pulmonary disease (OR 1.68, CI 1.00 to 2.81, p = 0.049), American Society of Anesthesiologists (ASA) grade ≥ 3 (OR 2.37, CI 1.13 to 4.97, p = 0.022), and length of stay ≥ nine days (OR 1.98, CI 1.18 to 3.31, p = 0.009). A total of 38 (58.5%) COVID-19 cases were probably hospital acquired infections. The false-negative rate of a negative swab on admission was 0% in asymptomatic patients and 2.9% in symptomatic patients. Conclusion. COVID-19 was independently associated with a three times increased 30-day mortality rate.

Aims. The first death in the UK caused by COVID-19 occurred on 5 March 2020. We aim to describe the clinical characteristics and outcomes of major trauma and orthopaedic patients admitted in the early COVID-19 era. Methods. A prospective trauma registry was reviewed at a Level 1 Major Trauma Centre. We divided patients into Group A, 40 days prior to 5 March 2020, and into Group B, 40 days after. Results. A total of 657 consecutive trauma and orthopaedic patients were identified with a mean age of 55 years (8 to 98; standard deviation (SD) 22.52) and 393 (59.8%) were males. In all, 344 (approximately 50%) of admissions were major trauma. Group A had 421 patients, decreasing to 236 patients in Group B (36%). Mechanism of injury (MOI) was commonly a fall in 351 (52.4%) patients, but road traffic accidents (RTAs) increased from 56 (13.3%) in group A to 51 (21.6%) in group B (p = 0.030). ICU admissions decreased from 26 (6.2%) in group A to 5 (2.1%) in group B. Overall, 39 patients tested positive for COVID-19 with mean age of 73 years (28 to 98; SD 17.99) and 22 (56.4%) males. Common symptoms were dyspnoea, dry cough, and pyrexia. Of these patients, 27 (69.2%) were
COVID 19 led to massive disruption of elective services across Scotland. This study was designed to assess the impact on elective service that the COVID-19 pandemic had, to what extent services have been restarted and the associated risks are in doing so. This is a retrospective observational study. The primary outcomes are the number of operations completed, 30-day mortality, 30-day complication rates and
Aims. It is imperative to understand the risks of operating on urgent cases during the COVID-19 (SARS-Cov-2 virus) pandemic for clinical decision-making and medical resource planning. The primary aim was to determine the mortality risk and associated variables when operating on urgent cases during the COVID-19 pandemic. The secondary objective was to assess differences in the outcome of patients treated between sites treating COVID-19 and a separate surgical site. Methods. The primary outcome measure was 30-day mortality. Secondary measures included complications of surgery, COVID-19 infection, and length of stay. Multiple variables were assessed for their contribution to the 30-day mortality. In total, 433 patients were included with a mean age of 65 years; 45% were male, and 90% were Caucasian. Results. Overall mortality was 7.6% for all patients and 15.9% for femoral neck fractures. The mortality rate increased from 7.5% to 44.2% in patients with fracture neck of femur and a COVID-19 infection. The COVID-19 rate in the 30-day postoperative period was 11%. COVID-19 infection, age, and Charlson Comorbidity Index were independent risk factor for mortality. Conclusion. There was a significant risk of contracting COVID-19 due to being admitted to hospital. Using a site which was not treating COVID-19 respiratory patients for surgery did not identify a difference with respect to mortality,
Aims. Elective orthopaedic surgery was cancelled early in the COVID-19 pandemic and is currently running at significantly reduced capacity in most institutions. This has resulted in a significant backlog to treatment, with some hospitals projecting that waiting times for arthroplasty is three times the pre-COVID-19 duration. There is concern that the patient group requiring arthroplasty are often older and have more medical comorbidities—the same group of patients advised they are at higher risk of mortality from catching COVID-19. The aim of this study is to investigate the morbidity and mortality in elective patients operated on during the COVID-19 pandemic and compare this to a pre-pandemic cohort. Primary outcome was 30-day mortality. Secondary outcomes were perioperative complications, including
The coronavirus 2019 (COVID-19) global pandemic has had a significant impact on trauma and orthopaedic (T&O) departments worldwide. To manage the peak of the epidemic, orthopaedic staff were redeployed to frontline medical care; these roles included managing minor injury units, forming a “proning” team, and assisting in the intensive care unit (ICU). In addition, outpatient clinics were restructured to facilitate virtual consultations, elective procedures were cancelled, and inpatient hospital admissions minimized to reduce
The coronavirus disease 2019 (COVID-19) pandemic has led to unprecedented challenges to healthcare systems worldwide. Orthopaedic departments have adopted business continuity models and guidelines for essential and non-essential surgeries to preserve hospital resources as well as protect patients and staff. These guidelines broadly encompass reduction of ambulatory care with a move towards telemedicine, redeployment of orthopaedic surgeons/residents to the frontline battle against COVID-19, continuation of education and research through web-based means, and cancellation of non-essential elective procedures. However, if containment of COVID-19 community spread is achieved, resumption of elective orthopaedic procedures and transition plans to return to normalcy must be considered for orthopaedic departments. The COVID-19 pandemic also presents a moral dilemma to the orthopaedic surgeon considering elective procedures. What is the best treatment for our patients and how does the fear of COVID-19 influence the risk-benefit discussion during a pandemic? Surgeons must deliberate the fine balance between elective surgery for a patient’s wellbeing versus risks to the operating team and utilization of precious hospital resources. Attrition of healthcare workers or Orthopaedic surgeons from restarting elective procedures prematurely or in an unsafe manner may render us ill-equipped to handle the second wave of infections. This highlights the need to develop effective screening protocols or preoperative COVID-19 testing before elective procedures in high-risk, elderly individuals with comorbidities. Alternatively, high-risk individuals should be postponed until the risk of
Abstract. Introduction. The risk of Covid-19 community and hospital acquired infection (HAI) on patient outcomes in trauma is still relevant. Patient's should be routinely consented for this risk to ensure informed consent for perioperative contraction. Method. A prospective audit was completed from December-March 2022 examining a consecutive series of patient admissions with capacity to consent. The standards for compliance was RCOS Toolkit 5#3 stating the importance of enhanced consent for risk of contraction, in operating and changes to care pathways. The target was 95% compliance. 2/2 contingency tables were generated to determine odds ratio for compliance versus Covid+ rate. Results. This audit generated 80 consecutive patients from which 28 were excluded as non-operative or lacking capacity. It was found that 25% (13/52) had been specifically consented for risks of Covid-19. The rate of PCR-positive results was 15% (8/52) with a mortality of 25%. Approximately 2% of patients in this series were informed of the risk and had a positive Covid-PCR. An odds ratio of 0.38 indicates that being informed of the risk is not associated with rate of infection e.g by adopting enhanced personal protective measures. Conclusions. The pandemic recovery has not removed this substantial community and
Aims. Elective operating was halted during the COVID-19 pandemic to increase the capacity to provide care to an unprecedented volume of critically unwell patients. During the pandemic, the orthopaedic department at the Aneurin Bevan University Health Board restructured the trauma service, relocating semi-urgent ambulatory trauma operating to the isolated clean elective centre (St. Woolos’ Hospital) from the main hospital receiving COVID-19 patients (Royal Gwent Hospital). This study presents our experience of providing semi-urgent trauma care in a COVID-19-free surgical unit as a safe way to treat trauma patients during the pandemic and a potential model for restarting an elective orthopaedic service. Methods. All patients undergoing surgery during the COVID-19 pandemic at the orthopaedic surgical unit (OSU) in St. Woolos’ Hospital from 23 March 2020 to 24 April 2020 were included. All patients that were operated on had a telephone follow-up two weeks after surgery to assess if they had experienced COVID-19 symptoms or had been tested for COVID-19. The nature of admission, operative details, and patient demographics were obtained from the health board’s electronic record. Staff were assessed for sickness, self-isolation, and COVID-19 status. Results. A total of 58 surgical procedures were undertaken at the OSU during the study period; 93% (n = 54) of patients completed the telephone follow-up. Open reduction and internal fixation of ankle and wrist fractures were the most common procedures. None of the patients nor members of their households had developed symptoms suggestive of COVID-19 or required testing. No staff members reported sick days or were advised by occupational health to undergo viral testing. Conclusion. This study provides optimism that orthopaedic patients planned for surgery can be protected from COVID-19
During the COVID-19 pandemic, video/phone consultations (VPC) were increasingly utilised as an alternative to face-to-face (F2F) consultations, to minimise
As of April 2010 all NHS institutions in the United Kingdom are required to publish data on surgical site infection, but the method for collecting this has not been decided. We examined 7448 trauma and orthopaedic surgical wounds made in patients staying for at least two nights between 2000 and 2008 at our institution and calculated the rate of surgical site infection using three definitions: the US Centers for Disease Control, the United Kingdom
Aims. The risk to patients and healthcare workers of resuming elective orthopaedic surgery following the peak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been difficult to quantify. This has prompted governing bodies to adopt a cautious approach that may be impractical and financially unsustainable. The lack of evidence has made it impossible for surgeons to give patients an informed perspective of the consequences of elective surgery in the presence of SARS-CoV-2. This study aims to determine, for the UK population, the probability of a patient being admitted with an undetected SARS-CoV-2 infection and their resulting risk of death; taking into consideration the current disease prevalence, reverse transcription-polymerase chain reaction (RT-PCR) testing, and preassessment pathway. Methods. The probability of SARS-CoV-2 infection with a false negative test was calculated using a lower-end RT-PCR sensitivity of 71%, specificity of 95%, and the UK disease prevalence of 0.24% reported in May 2020. Subsequently, a case fatality rate of 20.5% was applied as a worst-case scenario. Results. The probability of SARS-CoV-2 infection with a false negative preoperative test was 0.07% (around 1 in 1,400). The risk of a patient with an undetected infection being admitted for surgery and subsequently dying from the coronavirus disease 2019 (COVID-19) is estimated at approximately 1 in 7,000. However, if an estimate of the current global infection fatality rate (1.04%) is applied, the risk of death would be around 1 in 140,000, at most. This calculation does not take into account the risk of

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 nationwide multicentre retrospective cohort study of all patients with hip fracture in all 17 Scottish hospitals in March-April. Demographics, blood results, COVID-19 status, Nottingham Hip Fracture Score (NHFS), management, length of stay (LOS), and 30-day mortality were recorded. 78/833 (9.4%) patients had COVID-19 (65 swab-proven). 30-day survival with COVID-19 was lower than without (65.4% vs 91%; p<0.001). COVID-19 within 7 days of admission (likely community-acquired) was independently associated with male sex (OR 2.34, p=0.040, CI 1.04–5.25) and COVID-19 symptoms (OR 15.56, CI 6.61–36.60, p<0.001). COVID-19 within 7–30 days (probable hospital-acquired) was independently associated with male sex (OR 1.73, CI 1.05–2.87, p=0.032), NHFS □7 (OR 1.91, CI 1.09–3.34, p=0.024), pulmonary disease (OR 1.68, CI 1.00–2.81, p=0.049), ASA □3 (OR 2.37, CI 1.13–4.97, p=0.022) and LOS □9 days (OR 1.98, CI 1.18–3.31, p=0.009). 38/65 (58.5%) of COVID-19 cases were probably hospital-acquired. The false negative rate of swabs on admission was 0% in asymptomatic and 2.9% in symptomatic patients. COVID-19 was associated with a threefold-increased 30-day mortality.

Introduction: Older age is a risk factor for a poorer survival prognosis after hip fracture. Some other variables, such as male sex, dependency and dementia also contribute to a worse result expectations. However, since the association between surgery complications and other variables, such as age has been poorly researched, in this paper we study, within a major project on hip fractures, the association between age and
Implementation of new diagnostic methods (i.e. MALDI-TOF MS) has made it possible to identify coagulase-negative staphylococci (CoNS) to species level in routine practice. Further knowledge about clinical and microbiological characteristics of prosthetic joint infections (PJIs) caused by different CoNS may both facilitate interpretation of microbiological findings and improve clinical algorithms. The aim of this study was clinical and microbiological characterization of PJIs caused by Staphylococcus capitis. Patients with PJIs caused by S. capitis (growth in ≥2 perioperative tissue samples, n=19, identified by MALDI-TOF MS) from three centres between 2005–2014 were included. Medical records were examined (n=16). Further characterization of S. capitis was performed; rep-PCR (Diversilab, BioMerieux), standard antibiotic susceptibility testing, GRD Etest and macromethod Etest for detection of heteroresistant subpopulations and microtitre plate assay for detection of biofilm production. Multi-drug resistant (MDR) S. capitis (R≥3 antibiotic groups) was detected in 5/19(26%) of isolates, 1/19(5%) were ciprofloxacin resistant and no isolates was rifampin resistant. Biofilm formation was present in 14/19(74%). The dendrograms created by rep-PCR showed two distinct clusters, including one that contained isolates from all centres, as well as the reference isolates. Furthermore, three additional clusters were identified, all of these mainly obtained from single centres. In two of these, MDR was highly prevalent. In one of these clusters, 4 of the 8 strictly monomicrobial infections were found. All of the PJIs were defined as either early postinterventional (10/16) or chronic (6/16). No late haematogenous infection was found. The highest CRP values were reported in monomicrobial infections. Wound healing disturbances was noted in 8/10 early postinterventional infections. Fever was absent in chronic infections, sinus tracts rare (1/6), while pain was a common symptom (5/6). S. capitis has the potential to cause PJIs, both by itself as well as part of a polymicrobial infection. The antibiotic susceptibility patterns were more favourable than has previously been reported in S. epidermidis isolated from PJIs(1). Clinical data suggests that PJIs caused by S. capitis were acquired perioperatively or in the early postoperative phase. The clustering found by rep-PCR together with data showing high prevalence of S. capitis in the air of operation rooms during prosthetic joint surgery(2) implicates that

INTRODUCTION. In recent years, there has been a shift toward outpatient and short-stay protocols for patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). We developed a peri-operative THA and TKA short stay protocol following the Enhance Recovery After Surgery principles (ERAS), aiming at both optimizing patients’ outcomes and reducing the hospital length of stay. The objective of this study was to evaluate the implementation of our ERAS short-stay protocol. We hypothesized that our ERAS THA and TKA short-stay protocol would result in a lower complication rate, shorter hospital length of stay and reduced direct health care costs compared to our standard procedure. METHODS. We compared the complications rated according to Clavien-Dindo scale, hospital length of stay and costs of the episode of care between a prospective cohort of 120 ERAS short-stay THA or TKA and a matched historical control group of 150 THA or TKA. RESULTS. Significantly lower rate of Grade 1 and 2 complications in the ERAS short-stay group compared with the standard group (mean 0.8 vs 3.0, p<0.001). Postoperative complications that were experienced by significantly more patients in the control group included pain (67% vs 13%, p<0.001), nausea (42% vs 12%, p<0.001), vomiting (25% vs 0.9%, p<0.001), dizziness (15% vs 4%, p=0.006), headache (4% vs 0%, p=0.04), constipation (8% vs 0%, p=0.002), hypotension (26% vs 11%, p=0.003), anemia (8% vs 0%, p=0.002), oedema of the operated leg (9% vs 1%, p=0.005), persistent lameness (4% vs 0%, p=0.04), urinary retention (13% vs 4%, p=0.006) and anemia requiring blood or iron transfusion (8% vs 0%, p=0.002). No difference was found between the 2 groups for Grade 3, 4, or 5 complications. The mean hospital length of stay for the ERAS short-stay group decreased by 2.8 days for the THAs (0.1 vs 2.9 days, p bellow 0.001) and 3.9 days for the TKAs (1.0 vs 4.9 days, p<0.001). The mean estimated direct health care costs reduction with the ERAS short-stay protocol was 1489% per THA and 4206% per TKA. DISCUSSION AND CONCLUSION. Shorter hospitalization time after THA and TKA is associated with lower risk of
At the Orthopedic Hospital Vienna Speising 7.857 surgeries were performed in 2008. 2.211 of these surgeries required implants. The number of performed Total Hip Arthroplasties (THA) was 836. All of these surgeries were elective. Approximately 0,5% of the patients who underwent a surgery at our institution had a postoperative infection, 0,8% were admitted because of an already existing infection, which required treatment at our department. In order to achieve a basis for international compatibility and to meet the legal postulations the Orthopedic Hospital Vienna Speising actively participates in ANISS (Austrian
Purpose: Operative site infections can have catastrophic consequences after orthopaedic surgery. Prevention is particularly difficult due to the large number of factors involved. We describe here an exceptional epidemic of meti-R Staphylococcus aureus (MRSA) operative site infections whose source was successfully identified and eradicated. Material and methods: The epidemic affected seven patients who underwent orthopaedic surgery during a thirteen-month period. All patients developed acute MRSA operative site infection. The epidemic nature of the infections was confirmed by the bacteriological study which identified the causal germ as a specific MRSA strain very different from strains generally identified in hospital infections. The causal strain was sensitive to quinolones and resistant to amikacin. Antibiotic therapy prescribed in all cases was combined with surgical lavage in four patients. Search was undertaken to identify an environmental or human source. An audit of the operating theatre was performed and nasal swabs were obtained from all personnel present at the last operation complicated by operative site infection. One non-medical assistant was found to be a carrier of the same MRSA strain incriminated as the cause of the epidemic. Nasal application of mupirocin successfully eradicated the carrier-state. No new case of operative site infection was noted for more than fourteen months. Discussion: Operative site infections in orthopaedic surgery led to longer inpatient care and can compromise functional outcome. These

Wrist arthroscopy is a standard procedure in hand surgery for diagnosis and treatment of wrist injuries. Even though not generally recommended for similar procedures, general administration of perioperative antibiotic prophylaxis (PAP) is still widely used in wrist arthroscopy. A clinical ambispective dual-centre study was performed to determine whether PAP reduces postoperative infection rates after soft tissue-only wrist arthroscopies. Retrospective and prospective data was collected at two hospitals with departments specialized in hand surgery. During the study period, 464 wrist arthroscopies were performed, of these 178 soft-tissue-only interventions met the study criteria and were included. Signs of postoperative infection and possible adverse drug effects (ADEs) of PAP were monitored. Additionally, risk factors for surgical site infection (SSIs), such as diabetes mellitus and BMI, were obtained.Aims

Research into COVID-19 has been rapid in response to the dynamic global situation, which has resulted in heterogeneity of methodology and the communication of information. Adherence to reporting standards would improve the quality of evidence presented in future studies, and may ensure that findings could be interpreted in the context of the wider literature. The COVID-19 pandemic remains a dynamic situation, requiring continued assessment of the disease incidence and monitoring for the emergence of viral variants and their transmissibility, virulence, and susceptibility to vaccine-induced immunity. More work is needed to assess the long-term impact of COVID-19 infection on patients who sustain a hip fracture. The International Multicentre Project Auditing COVID-19 in Trauma & Orthopaedics (IMPACT) formed the largest multicentre collaborative audit conducted in orthopaedics in order to provide an emergency response to a global pandemic, but this was in the context of many vital established audit services being disrupted at an early stage, and it is crucial that these resources are protected during future health crises. Rapid data-sharing between regions should be developed, with wider adoption of the revised 2022 Fragility Fracture Network Minimum Common Data Set for Hip Fracture Audit, and a pragmatic approach to information governance processes in order to facilitate cooperation and meta-audit. This editorial aims to: 1) identify issues related to COVID-19 that require further research; 2) suggest reporting standards for studies of COVID-19 and other communicable diseases; 3) consider the requirement of new risk scores for hip fracture patients; and 4) present the lessons learned from IMPACT in order to inform future collaborative studies.

The total hip arthroplasty (THA) is an effective operation for the restoration of the hip function. The number of operations is steadily climbing and is going to reach new heights in the future. The most devastating complication is the deep infection of the joint and has to be treated with a total revision of the prostheses. The risk factors for an infection play a very important role in the preoperative assessment of the patient and for the antibiotic treatment. There are many different opinions on which risk factors are associated with the development of a deep infection in the literature. Our goal was to analyze and find the risk factors, which matter most in the clinical treatment of patients. We searched the database “PubMed” and “Embase” with the keywords: „(((hip AND infection)) AND (arthroplasty OR replacement)”. With the help of check lists and limits we extracted the most viable studies for our research. Risk factors associated with a deep infection included the BMI (Body mass index), male gender, prolonged duration of surgery, diabetes mellitus type 2, the ASA (American society of anesthesiologists) score, the Charlson score and the NNIS (National

Report of a case of migrating periprosthetic infection from a hip replacement to a contralateral knee joint undergoing a total knee replacement. We present a 74-year old female patient who underwent a total hip arthroplasty of the left hip after a subcapital fracture of the femur. Four months after the index procedure the patient presented with signs and symptoms of infection of the operated joint. Staph aureus and Enterococcus faecalis were recognized as the infecting bacteria. The implants were removed, cement spacers were placed and a total hip arthroplasty was performed again after three months. Unfortunately, infection ensued again and the patient underwent three more procedures until the joint was considered clean and t he hip remained flail without implants. The patient elected to undergo a total knee arthroplasty due to severe osteoarthritis of right knee. Intraoperatively tissue samples were taken and sent for cultures which identified Enterococcus faecalis present in the knee joint. Enterococcus migrated from the infected hip to nonoperated knee joint. Intravenous antibiotics were administered for three weeks but the knee presented with infection of the arthroplasty ten months after its insertion. The implants were removed the joint was debrided and cement spacers were inserted. The patient decided not to proceed with another procedure and she remains with the cement spacers in her knee. Rare report of migrating periprosthetic infection.
Periprosthetic joint infection (PJI) in total hip arthroplasty in the elderly may occur but has been subject to limited investigation. This study analyzed infection characteristics, surgical outcomes, and perioperative complications of octogenarians undergoing treatment for PJI in a single university-based institution. We identified 33 patients who underwent treatment for PJIs of the hip between January 2010 and December 2019 using our institutional joint registry. Mean age was 82 years (80 to 90), with 19 females (57%) and a mean BMI of 26 kg/m2 (17 to 41). Mean American Society of Anesthesiologists (ASA) grade was 3 (1 to 4) and mean Charlson Comorbidity Index was 6 (4 to 10). Leading pathogens included coagulase-negative Staphylococci (45%) and Aims

The aim of this meta-analysis was to determine the pooled incidence of postoperative urinary retention (POUR) following total hip and knee arthroplasty (total joint replacement (TJR)) and to evaluate the risk factors and complications associated with POUR. Two authors conducted searches in PubMed, Embase, Web of Science, and Scopus on TJR and urinary retention. Eligible studies that reported the rate of POUR and associated risk factors for patients undergoing TJR were included in the analysis. Patient demographic details, medical comorbidities, and postoperative outcomes and complications were separately analyzed. The effect estimates for continuous and categorical data were reported as standardized mean differences (SMDs) and odds ratios (ORs) with 95% CIs, respectively.Aims

This study aimed to investigate the risk of postoperative complications in COVID-19-positive patients undergoing common orthopaedic procedures. Using the National Surgical Quality Improvement Programme (NSQIP) database, patients who underwent common orthopaedic surgery procedures from 1 January to 31 December 2021 were extracted. Patient preoperative COVID-19 status, demographics, comorbidities, type of surgery, and postoperative complications were analyzed. Propensity score matching was conducted between COVID-19-positive and -negative patients. Multivariable regression was then performed to identify both patient and provider risk factors independently associated with the occurrence of 30-day postoperative adverse events.Aims

Silicon nitride spinal fusion cages have been successfully used in the treatment or correction of stenosis, disc herniation, trauma, and other deformities of the spinal column since 2008. To date over 14,000 devices have been implanted with perioperative and postoperative complication rates of less than 0.2%. This remarkable achievement is due in part to the material itself. Silicon nitride is an ideal interbody material, possessing high strength and fracture toughness, inherent phase stability, biocompatibility, hydrophilicity, excellent radiographic imaging, and bacterial resistance. These characteristics can lead to implants that aid in prevention of
Because life expectancy is increasing, the number of primary knee arthroplasties performed is projected to increase 673% by 2030, according to Westrich et al. Also, Toulson et al. in a recent study predict that the incidence of deep infection associated with primary total knee arthroplasty ranges from 1% to 2%. Periprosthetic knee infection is one of the most dramatic and difficult to manage complications following total knee arthroplasty. Therefore, periprosthetic knee infection will continue to be a significant complication and an economic burden in the future. Our objective was to identify the risk factors that may provide greater likelihood of infection and thus select high-risk patients and to take maximum prevention strategies. Case-control study, between infected and non infected patients, undergoing primary total knee arthroplasty between January 2008 and January 2013. The risk factors evaluated were: duration of hospital stay, surgery duration, prophylactic antibiotics and timing for administration, volume of blood transfusion, autologous blood recovery system use, anesthetic technique, ASA classification, Diabetes Mellitus, Obesity (BMI>30), immunosuppression and history of any infection in the month preceding surgery. The presence of infection was defined by the criteria of the Center for Disease Control for
Elective orthopaedic services have had to adapt to significant system-wide pressures since the emergence of COVID-19 in December 2019. Length of stay is often recognized as a key marker of quality of care in patients undergoing arthroplasty. Expeditious discharge is key in establishing early rehabilitation and in reducing infection risk, both procedure-related and from COVID-19. The primary aim was to determine the effects of the COVID-19 pandemic length of stay following hip and knee arthroplasty at a high-volume, elective orthopaedic centre. A retrospective cohort study was performed. Patients undergoing primary or revision hip or knee arthroplasty over a six-month period, from 1 July to 31 December 2020, were compared to the same period in 2019 before the COVID-19 pandemic. Demographic data, American Society of Anesthesiologists (ASA) grade, wait to surgery, COVID-19 status, and length of hospital stay were recorded.Aims

The incidence of MRSA infection is increasing worldwide. Costs incurred in treating MRSA infection are over twice that of normal patients, and the duration of hospital stay is up to 10 times longer. Risk factors are age, previous MRSA infection, prolonged hospitalization, patients from convalescent homes, immunocompromised states, vascular and pulmonary disease. Methods. A retrospective chart review was conducted on 14 patients who developed MRSA infection in our unit, over a period of six years. Data included: age, gender, neurological status, length of hospital and ICU admission, type of procedure performed, HIV status, co-morbidities, nutritional status, haemoglobin, sensitivities and treatment. Results. Age ranged from 2 to 52 (mean 15.75 years) and included four males, six females, and four children. Of the thirteen patients who developed Surgical Site Infection (SSI), nine were posterior surgical wounds. Two patients were HIV positive. Mean albumin and lymphocyte count was 34.88 and 2.37 respectively. The average wait to surgery was 23.8 hospital days, average length of ICU admission was 5.01 days. Signs of SSI developed at 11.75 days on average. Four cases showed sensitivity to Vancomycin, while ten were sensitive to Clindamycin. Patients were treated for a total of six weeks with antimicrobial therapy. Five patients required debridement, two required implant removal for chronic infection. Infection subsequently resolved in all patients. Conclusion. The risk factors were prolonged hospitalization, and posterior surgical wounds. Infection by community acquired MRSA was twice as common as
With resumption of elective spine surgery services in the UK following the first wave of the COVID-19 pandemic, we conducted a multicentre British Association of Spine Surgeons (BASS) collaborative study to examine the complications and deaths due to COVID-19 at the recovery phase of the pandemic. The aim was to analyze the safety of elective spinal surgery during the pandemic. A prospective observational study was conducted from eight spinal centres for the first month of operating following restoration of elective spine surgery in each individual unit. Primary outcome measure was the 30-day postoperative COVID-19 infection rate. Secondary outcomes analyzed were the 30-day mortality rate, surgical adverse events, medical complications, and length of inpatient stay.Aims
Methods
Prosthetic joint infection (PJI) remains a devastating complication of arthroplasty. There is significant heterogeneity in treatment approaches to these infections and information on their efficacy relies on single-centre studies. This is the first multi-centre study examining current treatment approaches to patients with PJI. A retrospective cohort study was conducted over a 3-year period (January 2006 – December 2008) involving 10 hospitals in Victoria, Australia. Cases of prosthetic joint infections of hips and knees were identified using an established statewide
Purpose. Antibiotic prophylaxis plays an important role in minimizing surgical site infections as well as other
Recent interest has focused on minimally invasive hip surgery, with less attention being directed to maximising the potential benefits of this type of surgery. We have developed a new multidisciplinary programme for patients undergoing total hip replacement in order to facilitate an overnight hip replacement service. The programme involves a pre-operative regimen of education and physiotherapy, a modified anaesthetic technique, a minimally invasive surgical approach and a portable local anaesthetic pump infusion for post-operative pain control. Strict inclusion and exclusion criteria were developed based on age, medical status and social circumstances. Patients were mobilised on the day of their operation and discharged home with an ‘outreach team’ support network. No patient complained that their discharge was early. Independent evaluation was performed using the Oxford Hip Questionnaire, the Merle d'Aubigné clinical rating system and Visual Analogue Pain Scores. Thirty seven patients underwent total hip replacement using the new protocol. The average length of stay was 1.2 days. The mean pain score on discharge was 1.3/10. The Oxford Hip Questionnaire and Merle d'Aubigné scores were comparable to patients who underwent surgery prior to the introduction of the new protocol. Minimising in-patient stay for total hip replacement benefits the patient by reducing exposure to
