Fixation only of Vancouver B Proximal Femoral Fractures (PFF's), specifically with Cemented Taper Slip stems (CTS) with an intact bone cement interface, has been shown to have reduced blood transfusion requirements and reoperations, compared to revision arthroplasty. This potentially carries the risk of stem subsidence and loosening, which negatively impacts functional outcome. The incidence of stem subsidence and associated fracture morphology have not previously been reported. We retrospectively reviewed all Vancouver B PFF's in primary THR around CTS stems treated with internal fixation only between June 2015 and March 2021 for fracture morphology (Low Spiral (LS), High Spiral (HS), Metaphyseal Split (MS) and Short Oblique (SO)), fracture union and stem subsidence. Interprosthetic fractures and inadequate follow up were excluded. Secondary outcomes were collected. Out of 577 cases on our local periprosthetic database, 134 Vancouver B PFF's around CTS stems were identified, of which 77 patients underwent ORIF only. Of these, 50 procedures were identified, 21 were lost to follow up and 6 patients died before 6 months. Age, mortality rate and ASA is presented. Review of Fracture morphology showed: 100% (3/3) of HS subsided (1 revised for loosening); 68 % (19/28) of MS subsided (1 revised for loosening); 11.1 % (2/18) of LS subsided (0 revised for loosening); 0% (1/1) of SO subsided. There were 2 revisions for non-union (LS group). No dislocations were recorded. There was a statistically significant association between Morphology and Subsidence P value 0.0004). Major subsidence was observed in 8 patients (3 HS, 4 MS and 1 LS) which was associated with a significance reduction in mobility. Subsidence was associated with negative symptoms (P value < 0.0001). Fixation of all Vancouver B PFF's does not produce uniformly good results. Revision rates following ORIF do not fully reflect patient outcomes. This trend will affect the NJR, stem rating and patient satisfaction. Subsidence after ORIF was associated with certain morphologies (HS & MS) and stem revision may be preferrable, in keeping with GIRFT. A morphology-based classification system can inform decision making

Background. The rate of elderly people over 65 year-old increased from 18.5 % in 2004 to 26.0% in 2015 in Japan. Northern part of Japan is a head of the super-aging society, and the rate already reached 30.9% in 2015. Along with aging society, rapid increase of total hip arthroplasties (THA) has been predicted. The aim of this study is to estimate the trend of total hip arthroplasties in our super-aging area in Northern Japan. Methods. Trend on number and rate of THA in one of the local area of leading super-aging society were surveyed in the last decade using the database of diagnostic procedure and surgical records from 2004 to 2015. The cause of revision THA was analyzed in 2004–2009 versus in 2010–2015. Spearman's rank-correlation coefficient and student's t-tests were performed using the PASW 18 software (SPSS Institute Inc). Values of p < 0.05 were considered statistically significant. Results. The data revealed 24,822 cases of orthopaedic surgery, including 4,845 THA from 2004 to 2015. The reason for THA contained 3,343 osteoarthritis (OA, 69 %), 485 traumas (10 %), 291 loosening (6 %). THA increased from 282 cases in 2004 to 450 in 2015 year by year. They contained 3,905 cases of primary THA (81 %), 405 revision THA (8 %), and 535 bipolar hip arthroplasties (11 %). The revision contained 300 aseptic loosening (74 %), and 69 infections (17 %), and 36 dislocations (9%). The value of infections and dislocation as cause of revision THA was larger compared to the value of all revision THA between in 2004–2009 and in 2010–2015 (2.0 and 1.6 times). Discussion. The number and rate of THA increased year by year, because of expansion of elderly people affected by OA in the super-aging society. The number of revision THA due to infections or dislocation may be still increasing year by year

Aim: To assess patient and surgery related factors to identify any trend leading to a stiff TKR. We also looked at the efficacy of MUA in the treatment of a stiff TKR. Material and Methods: Retrospective analysis of TKRs which have undergone MUA during the period from 01/01/1999 to 25/06/2005 at Peterborough Hospitals. We included primary TKRs with a minimum post MUA follow-up of six months. Results: Out of a total of 1809 TKRs, 42 TKRs (2.3%) in 38 patients required MUA. 26 (68%) were females with a median age of 67 years and a median BMI of 30. 34 (81%) had varus knees. Median pre-operative flexion was 100 deg. Median follow-up was 12 months (6 – 45 months). Median pre MUA flexion was 70 deg (15 – 100 deg.). Median surgery to MUA interval was 12 weeks (range: 10 days to 104 wks). Median gain in flexion during MUA was 35 deg (0 – 90 deg). At final follow-up, 74% had lost flexion gained at MUA (median loss: 17.5 deg, mean loss: 20 deg). 71% gained a median of 20 deg flexion with MUA (Mean: 25 deg, range: 15 – 85 deg). Median range of flexion at final follow-up was 90 deg (40 – 120 deg). Conclusion: We were unable to identify any distinct trends in relation to BMI, pre op flexion, other patient or surgical factors that would help predict occurrence of a stiff TKR. We advocate the use of MUA for a stiff TKR. 71% patients gained 20 to 25 deg flexion with MUA. 74% patients lost about 20 deg flexion gained at MUA. The average post MUA flexion at final follow up was 90 deg. This information is useful when counselling patients undergoing MUA. A protocol for management of stiff TKR is suggested

INTRODUCTION. This study is to determine the response of CRP after TKR surgery, both unilateral and simultaneous bilateral TKR. According to the previously published literature from North America and Europe CRP value peaks on the 1. st. and 2. nd. post-operative day and then gradually comes down to normal by 6–8 weeks post-operatively. AIM. To determine the trend of CRP in Indian patients undergoing TKR, both unilateral and simultaneous bilateral TKR. To see whether it follows the trend in North American and European population and to determine whether there is a difference in the CPR pattern in unilateral versus simultaneous bilateral TKR patients. MATERIAL & METHODS. Twenty six patients were included in this study. 13 patients each had unilateral TKR and simultaneous bilateral TKR. All the patients were operated by a single surgeon and assistant. Patients who had Rheumatoid arthritis and post operative adverse events like urinary tract infection were excluded from this study. All 26 patients were female patients and the mean age in the unilateral group was 67 years and in the simultaneous bilateral TKR group was 73 years. CRP levels were measured pre- operatively on 2. nd. day and 8 weeks. TKR was performed in a standard fashion. Both the groups received standard pre and post operative antibiotic prophylaxis. All patients received a posterior stabilized knee implant (Maxx Freedom Knee). RESULTS. In both the groups CRP level shot up on the 2. nd. post-operative day. Although the rise in CRP level was significantly higher in the simultaneous bilateral TKR group as against the unilateral TKR group. This difference was statistically significant. The CRP level came back to normal in about 39% of unilateral TKR patients at 8 weeks post operatively, while in majority (12 out of 13) of bilateral simultaneous TKR patient it was still elevated at 8 weeks post-op and had not come to normal. DISCUSSION. Macrophages are the important in the development of acute phase response namely CRP. The macrophages are present in the bone and bone marrow and less often in the skeletal muscle. The bone and bone marrow injury happening while performing TKR is responsible for elevation of CRP. Various North-American and European studies have shown that the CRP level increases significantly on the 1. st. postoperative day and the decreases from a peak on the 2. nd. postoperative day, attaining normal value at 6 to 8 weeks after operation. The result of our study are in variance to this published literature. Nearly 39% of our unilateral TKR patients and majority all of our simultaneous bilateral TKR patients did not achieve a normal CRP at 8 weeks after operation. These findings are significant as CRP is often used as a very sensitive indicator of post operative joint infection. Hence we conclude that the Indian TKR patients take longer time for the CRP values to become normal and the published literature regarding the normal levels of CRP in Unilateral TKR should not be extrapolated to simultaneous bilateral TKR group

Background The American Orthopaedic Foot and Ankle Society (AOFAS) score is one scoring system used to evaluate and monitor the progress of patients following foot and ankle surgery. The aim of this study was to evaluate the trend of AOFAS score over a period of time and correlate with quality-adjusted life-year (QALY) score, which is a valid and reliable scoring system. Method All patients undergoing surgery under one foot and ankle surgeon from a period of January 2001 to July 2003 were reviewed. The pre-operative AOFAS and QALY scores and post-operative at 3, 6, 12 months and yearly were collected prospectively. Results This study includes 205 surgical procedures in 159 patients. This included 40 patients with 41 feet in the ankle-hindfoot group; 15 patients with 15 feet in the midfoot group; 83 patients with 114 feet in the hallux group and 29 patients with 35 feet in the lesser toes group. The mean age of the patients was 51.9 yrs. The general trend of the AOFAS graph shows a mean of 45.3 pre-operatively which rises to 72.4 at 3 month and a peak of 77.1 at 6 months only to fall to 75.7 at 12 months. This fall though seemingly marginal was significant (p< 0.001) Kendall’s rank correlation was used to correlate the AOFAS and QALY score. The 6-month AOFAS score was found to have higher correlation with the final QALY score (τ =0.423) than the 12-month AOFAS score (τ =0.236). Conclusion AOFAS score correlates with subjective and functional results as determined by QALY score. The role of assessing AOFAS at 3 months does not seem to be justified. There is a deterioration in score at 12 months. Post-operative scores at 6 months should be sufficient to assess the outcome

Introduction. Spinal infections constitute a spectrum of disease comprising pyogenic, tuberculous, nonpyogenic-nontuberculous and postoperative spinal infections. The aim of this study was to review the epidemiology, diagnostic yield of first and second biopsy procedures and microbiology trends from Sheffield Spinal Infection Database along with analysing prognostic predictors in spinal infections. Materials & methods. Sheffield Spinal Infection Database collects data prospectively from regularly held Spinal infection MDTs. We accrued 125 spinal infections between September 2008 and October 2010. The medical records, blood results, radiology and bacteriology results of all patients identified were reviewed. In patients with negative first biopsy, second biopsy is contemplated and parenteral broad spectrum antibiotic treatment initiated. Results. There were 81 pyogenic, 16 tuberculous and 28 postoperative spinal infections. The mean age was 58.4 years (range, 19 to 88 years). There were 71 male and 54 female patients. There were 64 lumbar and 26 thoracic infections. Two level and multi-level spinal infections involving more than two segments occurred in 30 patients. Of sixty positive microbiology yields, the most common organism was methicillin sensitive staphylococcus aureus (n-23) followed by Streptococcal, E Coli and Coagulase negative staphylococcal and Pseudomonas infections. Second biopsy (done when first biopsy negative) was only positive in two patients. Conclusions. Annual incidence of de novo spinal infection was 48 (pyogenic-40, tuberculous-8). The most frequently isolated pathogen was Staphyloccus aureus. Multi-level infection, diabetic patients, resistant TB and postop infection in elderly patients constituted the ‘difficult to treat’ group in our experience. An algorithm for the diagnostic work-up and management of spinal infections is proposed

Minimal Invasive Surgery (MIS) in total knee arthroplasty (TKA) has gained much attention in the scientific community and the public in the last few years. There still exists confusion in the related terminology and different surgical techniques are recommended. Cost effectiveness and risk/benefit analysis are not available at the moment. There still remains controversy whether these new techniques represent only a modern trend or the future of TKA. MIS Unicondylar replacement has shown significant faster rehabilitation but the same reproducible radiographic and clinical results compared with the conventional open technique. In Oct 2003 we have started using MIS TKA in our hospital. After a significant learning curve the decision was made to do only MIS TKA from Nov. 2004 up to now. More than 300 cases were performed. Only few definite data are available at this stage. In 20% of the patients we performed the so called quad sparing (QS) technique. This offers a less invasive but very demanding and time consuming approach, where most of the surgery has to be performed from the side using complete new side cutting instruments. In the majority of our patients (80%) we performed a modified mini midvastus (MMI) approach, using standard 4 in 1 front cutting instruments. Electromagnetic navigation (EM) might be a helpful tool for MIS surgery in TKA. We have limited experience with this new EM navigation system in combination with the new MIS TKA surgical techniques. In a pilot study with two groups of patients the direct comparison between QS and MMI was evaluated. Clinical evaluation was performed by two scores (KSS and WOMAC) and five additional functional tests including straight leg raising, active motion, raising a chair, stair climbing and functional gait analysis. Testing was performed pre-op and at 1, 6 and 12 weeks post-op. Patients and investigators were blinded to the surgical technique (either QS or MMI). The average OR time was 92 min (70 to 130) for MMI and 110 (85 to 165) for QS respectively. There were no complications in the MMI and 1 (wound healing) in the QS group. There were no differences in the different scores and in the functional tests between the groups at any time. There is still controversy in the benefit-risk analysis for the different minimal invasive techniques. In our hospital the MIS future for TKA has already started. Patients’ satisfaction and significant earlier rehabilitation are the key advantages of these new surgical techniques. The much easier MMI technique is now the standard. Only in selected cases the more demanding QS technique is performed. According to the learning curve these new MIS techniques are for specialized surgeons only and require additional training programmes. Despite these facts, we do believe that MIS is the future of TKA surgery

Introduction. Hip arthroscopy is a relatively new procedure and evidence to support its use remains limited. Well-designed prospective clinical trials with long-term outcomes are required, but study design requires an understanding of current practice. Our aim was to determine temporal trends in the uptake of non-arthroplasty hip surgery in England between 2001 and 2011. Methods. Using procedure and diagnosis codes, we interrogated the Hospital Episode Statistics (HES) Database for all hip procedures performed between 2001 and 2011, excluding those relating to arthroplasty, tumour or infection. Osteotomy procedures were also excluded. Results. Between 2001 and 2011, 12,684 joint-preserving hip procedures were recorded, of which 5,133 were performed open and 7,551 arthroscopically. The number of arthroscopic hip procedures performed each year increased by 631%, from 263 in 2001, to 1660 in 2011. The number of open procedures performed increased by 271%, from 260 in 2001, to 785 in 2011. The median age-group was 35–39 years of age and 60% of patients were female. There was considerable variation in procedure rates between different Strategic Health Authorities. In 2011, the greatest number of joint-preserving hip procedures were performed in the South West at 9.4 per 100,000 population, whereas the least were performed in the North East at 2.3 per 100,000 population. The proportion of procedures performed arthroscopically was highest in the North West at 75%, and lowest in the East Midlands at 44%. Conclusions. The number of joint-preserving hip procedures performed has risen significantly between 2001 and 2011, with an exponential rise in the number performed arthroscopically since 2006. Well-designed multi-centre clinical trials are essential to justify these relatively new procedures. If this growth continues, these procedures are likely to represent a significant commissioning burden in the future. HES data is limited since it does not include data from the Private Sector

The Trent arthroplasty register reported that results of Hip arthroplasty in general setup were less than that reported from specialist centres by 5%. This independent prospective study tests the hypothesis that results of Birmingham Hip Resurfacing (BHR) arthroplasty from pioneering centres would not accurately represent the outcome of hip resurfacing when performed in general setup. All patients were prospectively followed for at least five years at Oswestry Hip outcome centre. The surgeons carrying out the operation prospectively provided surgical details and thereafter patients were followed using Oswestry hip questionnaire (OSHIP) at fixed intervals. Survival was assessed by Kaplan-Meier method. Results were compared to the published results of BHR from specialist centres. There were 679 patients, and 58 surgeons in the study. Mean age at operation was 51 years and mean follow up was 5.63 years. The predominant preopera-tive diagnosis was Osteoarthritis. Mean OSHIP score was 89.5. There were 29 (4.2%) failures mostly due to fracture neck of femur (34%). Out of 14 failures in the first year, 9 (64%) were due to fracture neck of femur. The Kaplan-Meier survival up to eight years is 95.354% in the current study. Compared to the published results, there were 2 to 19 times high failure rate which is significantly higher (p=0.001) than the published studies. Most of the early failures were due to fracture neck of femur in the first year. Hence we prove our hypothesis, as the results of BHR from specialist centres do not accurately reflect on the outcome in general setup. The discrepancy in the results is mostly due to fracture neck of femur in the early postoperative time. The results of this study will enhance awareness of the early trend in failures. Appropriate patient selection and meticulous surgical technique will help avoid this complication in the general setup, where most of the patients get benefited from BHR arthroplasty

The worldwide increase in the resistance of micro-organisms to antimicrobial drugs leads to an increase in morbidity, mortality and health care costs. It is important to identify the resistant organisms, to provide alternative antibiotic treatment protocols and to identify the high-risk infection areas.

We undertook a retrospective study of 693 musculoskeletal infections seen in the Musculoskeletal Tumour and Sepsis Unit of Pretoria Academic Hospital over five years, capturing data relating to the microscopy, culture and sensitivity to antimicrobial drugs of micro-organisms from tissue samples and pus swabs.

Most infections developed in patients aged 31 to 40 years. Sepsis most often occurred postoperatively. The next most common sepsis followed trauma. The femur was the most common site, followed by the tibia and the knee. In descending order, the most common organisms isolated were Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas sp., Escherichia coli, Enterobacter sp.

In the last two years there was an alarming increase in coagulase-negative staphylococci. All micro-organisms exhibited increased resistance to specific antimicrobial drugs over the five-year period.

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. Methods. 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. Results. This investigation included 739,474 spinal surgeries and 739,215 hospitalizations in Japan. There was an average annual increase of 4.6% in the number of spinal surgeries. Scheduled hospitalizations increased by 3.7% per year while unscheduled hospitalizations increased by 11.8% per year. In-hours surgeries increased by 4.5% per year while after-hours surgeries increased by 9.9% per year. Complication rates and costs increased for both after-hours surgery and unscheduled hospitalizations, in comparison to their respective counterparts of in-hours surgery and scheduled hospitalizations. Conclusion. This study provides important insights for those interested in improving spine care in an ageing society. The swift surge in after-hours spinal surgeries and unscheduled hospitalizations highlights that the medical needs of an increasing number of patients due to an ageing society are outpacing the capacity of existing medical resources.

Introduction. Anterior cruciate ligament reconstruction (ACLr) is the most widely published operation in the orthopaedic literature. Over recent years there has been increased interest in the surgical technique and role of concomitant procedures performed during ACLr. The National Ligament Registry (NLR) collects robust data on ACLr performed in the UK. In this registry analysis we explore trends in ACLr surgery and how they relate to published literature and the growing industry portfolio available to surgeons. Methods. Using data from the NLR, 14,352 ACLr performed between 2013–2021 were analysed. High impact papers on ACLr were then cross referenced against this data to see if surgical practice was influenced by literature or whether surgical practice dictated publication. Common trends were also compared to key surgical industry portfolios (Arthrex, Smith and Nephew) to see how new technology influenced surgical practice. Results. The number of ACLr performed in isolation is decreasing. The number of ACL reconstructions involving meniscal surgery shows an increasing trend since 2013, with 57% of ACLr in 2021 now involving meniscus surgery. The number of ACLr with lateral extra-articular tenodesis (LET) has increased sharply since 2018, preceding the stability trial publication in 2020. Graft preference and size has remained static despite the introduction of new graft harvest and fixation devices. Additional procedures such as other ligament reconstruction and additional cartilage surgery have also remained static over time. Conclusion. In this analysis we looked at surgical trends in ACLr and their relation to literature and industry. Meniscal intervention is increasing, in keeping with the growing level of literature in this area. In the setting of LET, a high impact level 1 study appears to have significantly changed the practice of UK surgeons with a sharp increase in the number of LET procedures being performed. Industry appears to have little influence on the change in surgical trends, suggesting high quality evidence is what drives innovation in ACLr while industry supports rather than influences innovation. It will be interesting to see the impact of the stability 2 study, recent work on the medial structures of the knee and the commissioning of cartilage centres on future trends

Acute Compartment Syndrome (ACS) is an orthopaedic emergency that can develop after a wide array of etiologies. In this pilot study the MY01 device was used to assess its ease of use and its ability to continuously reflect the intracompartmental pressure (ICP) and transmit this data to a mobile device in real time. This preliminary data is from the lead site which is presently expanding data collection to five other sites as part of a multi-center study. Patients with long bone trauma of the lower or upper extremity posing a possibility of developing compartment syndrome were enrolled in the study. Informed consent was obtained from the patients. A Health Canada licensed continuous compartmental pressure monitor (MY01) was used to measure ICP. The device was inserted in the compartment that was deemed most likely to develop ACS and ICP was continuously measured for up to 18 hours. Fractures were classified according to the AO/OTA classification. Patient clinical signs and pain levels were recorded by healthcare staff during routine in-patient monitoring and were compared to the ICP from the device. Important treatment information was pulled from the patient's chart to help correlate all of the patient's data and symptoms. The study period was conducted from November 2020 through December 2021. Twenty-six patients were enrolled. There were 17 males, and nine females. The mean age was 38 years (range, 17–76). Seventeen patients received the device post-operatively and nine received it pre-operatively. Preliminary results show that post-operative ICPs tend to be significantly higher than pre-operative ICPs but tend to trend downwards very quickly. The trend in this measurement appears to be more significant than absolute numbers which is a real change from the previous literature. One patient pre-operatively illustrated a steep trend upwards with minimal clinical symptoms but required compartment release at the time of surgery that exhibited no muscle necrosis. The trend in this patient was very steep and, as predicted, predated the clinical findings of compartment syndrome. This trend allows an early warning signal of the absolute pressure, to come, in the compartment that is being assessed by the device. Preliminary results suggest that this device is reliable and relatively easy to use within our institutions. In addition it suggests that intracompartmental pressures can be higher immediately post-op but lower rapidly when the patient does not develop ACS. These results are in line with current literature of the difference between pre and post-operative baselines and thresholds of ICP, but are much more striking, as continuous measurements have not been part of the data set in most of past studies. Further elucidation of the pressure thresholds and profiles are currently being studied in the ongoing larger multicenter study and will add to our understanding of the critical values. This data, plus the added value of continuous trends in the pressure, upwards or downwards, will aid in preventing muscle necrosis during our management of these difficult long bone fractures

Clinical commissioning groups (CCG) have been replaced with ICBs that will bring together NHS and social care for the local population. ICBs are allocating contracts for long waiters for total hip replacements (THR) to hospitals that have achieved pre-covid volumes of THR, THR volumes undertaken by hospitals in 2022 should be at 2019 levels or more. Purpose of this study was to identify whether NHS hospitals in England are at a disadvantage in procuring ICB contracts for THR. THR volumes for NHS and independent sector (IND) hospitals from January 2012 to November 2022 were identified via National Joint Registry. Regional and national trend for THR volumes were identified for both NHS and IND hospitals using linear regression analysis. Trends of THR for NHS hospitals showed either stagnation or reduction in volume from 2014–2019. In 2022, nationally THR volume of NHS was 70% of 2019 (Figure 1). Trend of THR volume for IND hospitals nationally was a strong uptrend from 2012 to 2022 with a break only in 2020 due to COVID pandemic (Figure 2). Since the pandemic IND have overtaken NHS hospitals in volumes of THR undertaken. Similar picture of trends evolves when THR trends were assessed on a region by region basis. With NHS hospitals not back to pre-pandemic THR volumes, IND hospitals have a distinct advantage in securing more contracts via ICB. This in turn puts NHS hospitals at risk of taking on more complex and medically unwell patients potentially worsening NJR outcomes for NHS hospitals. The reasons for the lag in NHS hospitals’ THR volumes are multifactorial, not limited to continued bed pressures, increased emergency and unplanned admissions, staff shortages and sickness, pension taxations preventing doctors from undertaking more THR. However, lack of access to contracts from ICB will put NHS hospitals at huge financial and existential risk for elective care. For any figures or tables, please contact the authors directly

The objectives of this study are to evaluate the impact of the CoVID-19 pandemic on the development of relevant emerging digital healthcare trends and to explore which digital healthcare trend does the health industry need most to support HCPs. A web survey using 39 questions facilitating Five-Point Likert scales was performed from 1.8.2020 – 31.10.2020. Of 260 participants invited, 90 participants answered the questionnaire. The participants were located in the Hospital/HCP sector in 11.9%, in other healthcare sectors in 22.2%, in the pharmaceutical sector in 11.1%, in the medical device and equipment industry in 43.3%. The Five-Point Likert scales were in all cases fashioned as from 1 (strongly disagree) to 5 (strongly agree). As the top 3 most impacted digital health care trends strongly impacted by CoVID-19, respondents named:. - remote management of patients by telemedicine, mean answer 4.44. - shared data governance under patient control, mean answer 3.80. - new virtual interaction between HCP´s and medical industry, mean answer 3.76. Respondents were asked which level of readiness of the healthcare system currently possess to cope with the current trend impacted by CoVID-19. - Digital and efficient healthcare logistics, mean answer 1.54. - Integrated health care, mean answer 1.73. - Use of big data and artificial intelligence, mean answer 2.03. Asked if collaborative research in the form of digital data platforms for research data sharing and increasing collaboration with multi-centric consortia would have a positive impact on the healthcare sector, the agreement was high with a value of mean 4.10 on the scale. We can conclude that the impact of COVID-19 appears to be a high agreement of necessary advances in digitalization in the health care sector and in the collaboration of HCPs with the health care industry. Health care professional are unsure, in how far the national health care sector is capable of transformation in healthcare logistics and integrated health care

Introduction. Total ankle replacement (TAR) is performed for post-traumatic arthritis, inflammatory arthropathy, osteoarthritis and other indications. The Scottish Arthroplasty Project (SAP) began collection of data on TAR in 1997. In this study, using data from the SAP, we look at trends in the use and outcomes of TAR in Scotland. Methods. We identified 499 patients from the SAP who underwent TAR between 1997 and 2015 with imaging available on the National Picture Archiving and Communication System (PACS). We identified, and looked at trends in, implant type over the following time periods: 1998–2005; 2006–2010 and 2011–2015. Age, gender, indication and outcomes for each time period were examined and also trends with implant type over time. Results. There were 499 primary TAR procedures with an overall incidence of 0.5/10. 5. population per year. Eight different implants were identified with significant changes in the numbers of each type used over time. The peak incidence of TAR was in the 6th decade. The mean age of patients undergoing TAR from 59 years in 1997–2005, to 65 years in 2011–15 (p< 0.0001). The percentage of patients with inflammatory arthropathy was 52% in 1997–2005, compared with 10% in 2011–2015. Subsequent arthrodesis and infection rates appeared to be higher during the first time period. The female to male ratio also changed over time. The incidence of TAR increased overall during the study period (r= 0.9, p=< 0.0001). This may be due to a broadening range of indications and patient selection criteria, in turn due to increased surgeon experience and the evolution of implant design. Conclusion. This study examines a large number of TARs from an established arthroplasty registry. The rate of TAR has increased significantly in Scotland from 1997 to 2015. Indication and patient age has changed over time and this could potentially impact outcomes after ankle replacement

Hip arthroscopy (HA) and pelvic osteotomy (PO) are surgical procedures used to treat a variety of hip pathology affecting young adults, including femoroacetabular impingement and hip dysplasia respectively. This study aimed to investigate the trends and regional variation in the provision of HA and PO across England from 2010 to 2023 to inform healthcare resource allocation. We analysed the National Hospital Episode Statistics database for all HA and PO procedures in NHS England using specific OPCS-4 codes: HA: ‘W83+Z843’ or ‘W84+Z843’; PO: ‘X222+Z75’. We collected patient demographics, age, sex, and region of treatment. We performed descriptive and regression analyses to evaluate temporal trends in PO volume, age, sex and regional variation. 22,401 HAs and 1,348 POs were recorded between 2010 and 2023. The annual number of HAs declined by 28.4%, whilst the number of POs increased by 64% (p<0.001). Significantly more females underwent PO vs HA (90% vs 61.3%) and were older than males undergoing the same procedure (PO: 29.0±8.7 vs 25.8±9.2 years; HA: 36.8±12.0 years vs 35.8±11.2 years, p<0.001). For HA, the mean age of both sexes decreased by 3.3 and 2.9 years respectively (p<0.001), whereas the age of PO patients did not change significantly over the study period. There were significant regional variations with a mean incidence of 1.60/100,00 for HA (ranging from 0.70–2.66 per 100,000) and 0.43/100,000 for PO (ranging from 0.08–2.07 per 100,000). We have observed a decline in HA volume in England, likely due to improved patient selection and the impact of COVID-19, whilst PO volume has significantly increased, with regional variation persisting for both procedures. These trends highlight the need for equitable HA and PO access to improve patient outcomes and call for strategic healthcare planning and resource allocation to reduce disparities and improve training opportunities

This study aimed to examine the changing trends in the reasons for total hip replacement (THR) revision surgery, in one country over a twenty-one year period, in order to assess whether changes in arthroplasty practices have impacted revision patterns and whether an awareness of these changes can be used to guide clinical practice and reduce future revision rates. The reason for revision THR performed between January 1999 and December 2019 was extracted from the New Zealand Joint Registry (NZJR). The results were then grouped into seven 3-year periods to allow for clearer visualization of trends. The reasons were compared across the seven time periods and trends in prosthesis use, patient age, gender, BMI and ASA grade were also reviewed. We compared the reasons for early revision, within one year, with the overall revision rates. There were 20,740 revision THR registered of which 7665 were revisions of hips with the index procedure registered during the 21 year period. There has been a statistically significant increase in both femoral fracture (4.1 – 14.9%, p<0.001) and pain (8.1 – 14.9%, p<0.001) as a reason for hip revision. While dislocation has significantly decreased from 57.6% to 17.1% (p<0.001). Deep infection decreased over the first 15 years but has subsequently seen further increases over the last 6 years. Conversely both femoral and acetabular loosening increased over the first 12 years but have subsequently decreased over the last 9 years. The rate of early revisions rose from 0.86% to 1.30% of all revision procedures, with a significant rise in revision for deep infection (13-33% of all causes, p<0.001) and femoral fracture (4-18%, p<0.001), whereas revision for dislocation decreased (59-30%, p<0.001). Adjusting for age and gender femoral fracture and deep infection rates remained significant for both (p<0.05). Adjusting for age, gender and ASA was only significant for infection. The most troubling finding was the increased rate of deep infection in revision THR, with no obvious linked pattern, whereas, the reduction in revision for dislocation, aseptic femoral and acetabular loosening can be linked to the changing patterns of the use of larger femoral heads and improved bearing surfaces

The aim of this study was to determine the incidence, annual trend, perioperative outcomes, and identify risk factors of early-onset (≤ 90 days) deep surgical site infection (SSI) following primary total knee arthroplasty (TKA) for osteoarthritis. Risk factors for early-onset deep SSI were assessed. We performed a retrospective population-based cohort study using prospectively collected patient-level data from several provincial administrative data repositories between January 2013, and March 2020. The diagnosis of early-onset deep SSI was based on published Centre for Disease Control/National Healthcare Safety Network (CDC/NHSN) definitions. The Mann-Kendall Trend Test was used to detect monotonic trends in early-onset deep SSI rates over time. The effects of various patient and surgical risk factors for early-onset deep SSI were analyzed using multiple logistic regression. Secondary outcomes were 90-day mortality and 90-day readmission. A total of 20,580 patients underwent primary TKA for osteoarthritis. Forty patients had a confirmed deep SSI within 90-days of surgery representing a cumulative incidence of 0.19%. The annual infection rate did not change over the 7-year study period (p = 0.879). Risk factors associated with early-onset deep SSI included blood transfusions (OR, 3.93 [95% CI 1.34-9.20]; p=0.004), drug or alcohol abuse (OR, 4.91 [95% CI 1.85-10.93]; p<0.001), and surgeon volume less than 30 TKA per year (OR, 4.45 [1.07-12.43]; p=0.013). Early-onset deep SSI was not associated with 90-days mortality (OR, 11.68 [0.09-90-58]; p=0.217), but was associated with an increased chance of 90-day readmission (OR, 50.78 [26.47-102.02]; p<0.001). This study establishes a reliable baseline infection rate for early-onset deep SSI after TKA for osteoarthritis through the use of a robust methodological process. Several risk factors for early-onset deep SSI are potentially modifiable or can be optimized prior to surgery and be effective in reducing the incidence of early-onset SSI. This could guide the formulation of provincial screening programs and identify patients at high risk for SSI

Aim. Prosthetic joint infection (PJI) is a devastating complication of joint replacement, having an impact on morbimortality but also on national health systems and their budgets. The current situation of PJI-related hospitalizations in Spain and their changes over time are unknown. Therefore, we aimed to analyze the hospitalization burden of PJI, including costs and trends in recent decades. Methods. Retrospective observational study including data from the National Surveillance System for Hospital Data, which includes more than 98% of Spanish hospitals. During the period 2000–2015, hospitalizations due to PJI (ICD-9-CM 996.66) as main diagnosis were included. Epidemiological trends were evaluated during four periods: P1, 2000–2003; P2, 2004–2007; P3, 2008–2011; P4, 2012–2015. Annual hospitalization rates per 100,000 inhabitants and trends were also calculated. Results. Among 5,721,6725 hospitalizations, 49,835 were PJI related, which represented 8.71/10,000 admissions. We observed a significant increase in the number of PJI-related hospitalizations per 10,000 admissions during the study period: 6.43 P1, 8.53 P2, 9.60 P3, 10.05 P4 (p<0.001). The annual hospitalization rate was 6.9/100,000 inhabitants (95%CI 6.9–7), which also increased over time (p<0.001). The median age was 72 years (IQR 65–78) and 58.12% were women. Hospitalization rates were higher in women (7.95 vs 5.90; p<0.001) and also increased with patients’ age (p<0.001). Whereas the median length of stay was 7 days (IQR 7–8) in the global cohort, it was 18 days (IQR 10–31) in those with PJI-related hospitalization; however, the median length of stay in PJI-related hospitalizations decreased during the study period (P1 20 days, P4 16 days, p<0.001). The total cost for the healthcare system was 366 million euros and the median cost per patient was 6937 euros (IQR 3584–10505), which significantly increased from 4804 euros in P1 to 8534 in P4 (p<0.001). The majority of patients (90.32%) were discharged home and the case-fatality rate was 2.70%, without significant differences during the study (p=0.384). Conclusions. In Spain, PJI-related hospitalizations have increased in recent decades, with higher costs despite the decrease in length of stay. PJI is a first magnitude healthcare problem, which should be prioritized in health systems and budgets
