The escalating demand for medical resources to address spinal diseases as society ages is an issue that requires careful evaluation. However, few studies have examined trends in spinal surgery, especially unscheduled hospitalizations or surgeries performed after hours, through large databases. Our study aimed to determine national trends in the number of spine surgeries in Japan. We also aimed to identify trends in after-hours surgeries and unscheduled hospitalizations and their impact on complications and costs. We retrospectively investigated data extracted from the Diagnosis Procedure Combination database, a representative inpatient database in Japan. The data from April 2010 to March 2020 were used for this study. We included all patients who had undergone any combination of laminectomy, laminoplasty, discectomy, and/or spinal arthrodesis.Aims

Dual mobility (DM) bearings are an attractive treatment option to obtain hip stability during challenging primary and revision total hip arthroplasty (THA) cases. The purpose of this study was to analyze data submitted to the American Joint Replacement Registry (AJRR) to characterize utilization trends of DM bearings in the USA. All primary and revision THA procedures reported to AJRR from 2012 to 2018 were analyzed. Patients of all ages were included and subdivided into DM and traditional bearing surface cohorts. Patient demographics, geographical region, hospital size, and teaching affiliation were assessed. Associations were determined by chi-squared analysis and logistic regression was performed to assess outcome variables.Aims

Introduction. Total joint arthroplasty rates have increased dramatically in recent decades. However, a comprehensive analysis of trends in revision total hip arthroplasty has not been performed recently to address the changing volume, costs, and location of these complex cases. We sought to identify trends in volume of these procedures, geographic distribution changes, and cost trends using a national sample. Materials and methods. The National Inpatient Sample, a representative sample of all hospital discharges within the United States, was used to determine the volume of revision total hip arthroplasty (THA) from 1993 to 2014. Procedures were identified by ICD-9 codes corresponding to revision THA. Annual incidence of revision THA was compared to annual incidence of primary THA to determine whether relative growth of revisions differed proportionally from the primary procedure. State-specific data was analyzed where available to develop geographic trend maps in the incidence of revision THA procedures using the estimated state population for years under review.
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. 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.Introduction

Summary Statement. Navigated total knee arthroplasty (TKA) is becoming increasingly popular in the United States. Compared to traditional unnavigated TKA, the use of navigation is associated with decreased blood transfusions and shorter hospital stays. Introduction. Navigated total knee arthroplasty (TKA) is a recent modification to standard TKA with many purported benefits in regards to component positioning. Controversy currently exists though regarding its clinical benefits. The purpose of this study was to assess recent national trends in navigated and unnavigated total knee arthroplasty and to evaluate perioperative outcomes for each group. Methods. International Classification of Disease - 9th Revision (ICD-9) procedure codes were used to search the National Hospital Discharge Survey (NHDS) for all patients admitted to US hospitals after navigated and unnavigated TKA for each year between 2005 and 2010. Data regarding patient demographics, hospitalization length, discharge disposition, blood transfusions, deep vein thrombosis, pulmonary embolism, mortality, and hospital location were gathered from the NHDS.
Summary Statement. Pulmonary embolism (PE) after total knee arthroplasty can have a significant impact on patient outcomes and healthcare costs. Efforts to prevent or minimise PE over the last 10 years have not had a significant impact on its occurrence at the national level. Introduction. Pulmonary embolism (PE) is a rare but known potentially devastating complication of total knee arthroplasty (TKA). Significant healthcare resources and pharmaceutical research has been recently focused on preventing this complication but limited data exists regarding the early results of this great effort. The purpose of this study was to assess recent national trends in PE occurrence after TKA and evaluate patient outcomes related to this adverse event. Methods. International Classification of Disease - 9th Revision (ICD-9) procedure codes were used to search the National Hospital Discharge Survey (NHDS) for all patients admitted to US hospitals after primary TKA for each year between 2001 and 2010. ICD-9 diagnosis codes were then used to identify patients from this population who developed an acute PE during the same admission. Data regarding patient demographics, hospitalization length, discharge disposition, deep vein thrombosis, mortality, and hospital size/location were gathered from the NHDS.
Summary Statement. Total hip arthroplasty and hemi-arthroplasty are becoming increasingly popular in the treatment of femoral neck fractures in the United States. Both appear to be safe and effective treatment options, with rare acute adverse events and low mortality. Introduction. Femoral neck fractures are one of the most frequent orthopaedic injuries seen in the United States (US). Total hip arthroplasty (THA) and hemiarthroplasty (HA) are commonly used to treat displaced intra-capsular femoral neck fractures, but controversy currently exists regarding the preferred modality. The purpose of this study was to assess recent national trends in THA and HA performed for femoral neck fracture and to evaluate perioperative outcomes for each treatment group. Methods. International Classification of Disease - 9th Revision (ICD-9) diagnosis codes were used to search the National Hospital Discharge Survey (NHDS) for all patients admitted to US hospitals after femoral neck fracture for each year between 2001 and 2010. ICD-9 procedure codes were then used to identify patients from this fracture population who underwent THA or HA. Data regarding patient demographics, hospitalization length, discharge disposition, in-hospital adverse events (pulmonary embolus, deep vein thrombosis, blood transfusion, mortality) and hospital size/location were gathered from the NHDS.
Proximal humerus fractures (PHF) are common, accounting for approximately 5% of all fractures. Approximately 30% require surgical intervention which can range from open reduction with internal fixation (ORIF) to shoulder arthroplasty (including hemiarthroplasty, total shoulder arthroplasty, (TSA) or reverse total shoulder arthroplasty (RTSA)). The aim of this study was to assess trends in operative interventions for PHF in an Australian population. Data was retrospectively collected for patients diagnosed with a PHF and requiring surgical intervention between January 2001 and December 2020. Data for patients undergoing ORIF were extracted from the Medicare database, while data for patients receiving arthroplasty for PHF were obtained from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR). Across the study period, ORIF was the most common surgical procedure for management of PHFs. However, since 2019, RTSA has surpassed ORIF as the most common surgical procedure to treat PHFs, accounting for 51% of operations. While the number of RTSA procedures for PHF has increased, ORIF and shoulder hemiarthroplasty has significantly reduced since 2007 (p < 0.001). TSA has remained uncommon across the follow-up period, accounting for less than 1% of all operations. Patients younger than 65 years were more likely to receive ORIF, while those aged 65 years or greater were more likely to receive hemiarthroplasty or RTSA. While the number of ORIF procedures has increased during the period of interest, it has diminished as a proportion of overall procedure volume. RTSA is becoming increasingly popular, with decreasing utilization of hemiarthroplasty, and TSA for fracture remaining uncommon. These trends provide information that can be used to guide resource allocation and health provision in the future. A comparison to similar data from other nations would be useful.
Total ankle replacement (TAR) is performed for inflammatory arthropathy, osteoarthritis and other indications. The Scottish Arthroplasty Project (SAP) began collection of data on TAR in 1998. In this study, we look at trends in the use and outcomes of TAR in Scotland. We identified patients from the SAP who underwent TAR between 1998 and 2015 with imaging available on the National Picture Archiving and Communication System (PACS). We identified, and examined trends in implant type over the following time periods: 1998–2005; 2006–2010 and 2011–2015. Age, gender, indication, outcomes and trends in implants used for each time period were examined. There were 499 primary TAR procedures with an overall incidence of 0.5/105 population per year. Eight 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 and mean age of patients increased from 59 years in 1998–2005, to 65 years in 2011–15 (p<0.0001). The percentage of patients with inflammatory arthropathy was 49% in 1998–2005, compared with 10% in 2011–2015. Arthrodesis and infection rates appeared to be higher during the first time period. The male to female ratio changed over time. The incidence of TAR increased overall during the study period (r= 0.9, p=<0.0001). This study examines a large number of TARs from an established arthroplasty registry. The rate of TAR has increased significantly in Scotland from 1998 to 2015. Indications and patient age have changed over time and could impact outcomes after ankle replacement.
Open limb fractures are typically due to a high energy trauma. Several recent studied have showed treatment's superiority when a multidisciplinary approach is applied. World Health Organization reports that isolate limb traumas have an incidence rate of 11.5/100.000, causing high costs in terms of hospitalization and patient disability. A lack of experience in soft tissue management in orthopaedics and traumatology seems to be the determining factor in the clinical worsening of complex cases. The therapeutic possibilities offered by microsurgery currently permit simultaneous reconstruction of multiple tissues including vessels and nerves, reducing the rate of amputations, recovery time and preventing postoperative complications. Several scoring systems to assess complex limb traumas exist, among them: NISSSA, MESS, AO and Gustilo Anderson. In 2010, a further scoring system was introduced to focus open fractures of all locations: OTA-OFC. Rather than using a single composite score, the OTA-OFC comprises five components grades (skin, arterial, muscle, bone loss and contamination), each rated from mild to severe. The International Consensus Meeting of 2018 on musculoskeletal infections in orthopaedic surgery identified the OTA-OFC score as an efficient catalogue system with interobserver agreement that is comparable or superior to the Gustilo-Anderson classification. OTA-OFC predicts outcomes such as the need for adjuvant treatments or the likelihood of early amputation. An orthoplastic approach reconstruction must pay adequate attention to bone and soft tissue infections management. Concerning bone management: there is little to no difference in terms of infection rates for Gustilo-Anderson types I–II treated by reamed intramedullary nail, circular external fixator, or unreamed intramedullary nail. In Gustilo-Anderson IIIA-B fractures, circular external fixation appears to provide the lowest infection rates when compared to all other fixation methods. Different technique can be used for the reconstruction of bone and soft tissue defects based on each clinical scenario. Open fracture management with fasciocutaneous or muscle flaps shows comparable outcomes in terms of bone healing, soft tissue coverage, acute infection and chronic osteomyelitis prevention. The type of flap should be tailored based on the type of the defect, bone or soft tissue, location, extension and depth of the defect, size of the osseous gap, fracture type, and orthopaedic implantation. Local flaps should be considered in low energy trauma, when skin and soft tissue is not traumatized. In high energy fractures with bone exposure, muscle flaps may offer a more reliable reconstruction with fewer flap failures and lower reoperation rates. On exposed fractures several studies report precise timing for a proper reconstruction. Hence, timing of soft tissue coverage is a critical for length of in-hospital stay and most of the early postoperative complications and outcomes. Early coverage has been associated with higher union rates and lower complications and infection rates compared to those reconstructed after 5-7 days. Furthermore, early reconstruction improves flap survival and reduces surgical complexity, as microsurgical free flap procedures become more challenging with a delay due to an increased pro-thrombotic environment, tissue edema and the increasingly friable vessels. Only those patients presenting to facilities with an actual dedicated orthoplastic trauma service are likely to receive definitive treatment of a severe open fracture with tissue loss within the established parameters of good practice. We conclude that the surgeon's experience appears to be the decisive element in the orthoplastic approach, although reconstructive algorithms may assist in decisional and planification of surgery.
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.
Minimum clinically important differences (MCIDs) are critical to understanding changes in patient-reported outcome measure (PROM) scores after total joint arthroplasty (TJA). The usage and adoption of MCIDs not been well-studied. This study was performed to IDENTIFY trends in PROM and MCID use after TJA over the past decade. All articles published in the calendar years of 2010 and 2020 in CORR, JBJS, and the Journal of Arthroplasty were reviewed. Articles relating to clinical outcomes in primary total hip arthroplasty (THA) or total knee arthroplasty (TKA) were included. For each article, all reported PROMs and (if present) accompanying MCIDs were recorded. The use of PROMs and MCIDs were compared between articles published in 2010 and 2020.Abstract
Introduction
Methods
The management of hip fractures has advanced on all aspects from prevention, specialised hip fracture units, early operative intervention and rehabilitation in line with increasing incidence in an aging population. Accurate data analysis on the incidence and trends of hip fractures is imperative to guide future management planning. A review of all articles published on mortality after hip fracture over a twenty year period (1999–2018) was undertaken to determine any changes that had occurred in the demographics and mortality over this period. This article complements and expands upon the findings of a previous article by the authors assessing a four decade period (1959 – 1998) and attempts to present trends and geographical variations over sixty years.Abstract
Introduction
Methods
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.
The aim of this study is to evaluate the change in incidence rate of shoulder arthroplasty, indications, and surgeon volume trends associated with these procedures between January 2003 and April 2021 in the province of Nova Scotia, Canada. A total of 1,545 patients between 2005 and 2021 were analyzed. Patients operated on between 2003 and 2004 were excluded due to a lack of electronic records. Overall, 84.1% of the surgeries (n = 1,299) were performed by two fellowship-trained upper limb surgeons, with the remainder performed by one of the 14 orthopaedic surgeons working in the province.Aims
Methods
The current study aimed to compare robotic arm-assisted (RA-THA), computer-assisted (CA-THA), and manual (M-THA) total hip arthroplasty regarding in-hospital metrics including length of stay (LOS), discharge disposition, in-hospital complications, and cost of RA-THA versus M-THA and CA-THA versus M-THA, as well as trends in use and uptake over a ten-year period, and future projections of uptake and use of RA-THA and CA-THA. The National Inpatient Sample was queried for primary THAs (2008 to 2017) which were categorized into RA-THA, CA-THA, and M-THA. Past and projected use, demographic characteristics distribution, income, type of insurance, location, and healthcare setting were compared among the three cohorts. In-hospital complications, LOS, discharge disposition, and in-hospital costs were compared between propensity score-matched cohorts of M-THA versus RA-THA and M-THA versus CA-THA to adjust for baseline characteristics and comorbidities.Aims

The purpose of this study was to evaluate trends in opioid use
after unicompartmental knee arthroplasty (UKA), to identify predictors
of prolonged use and to compare the rates of opioid use after UKA,
total knee arthroplasty (TKA) and total hip arthroplasty (THA). We identified 4205 patients who had undergone UKA between 2007
and 2015 from the Humana Inc. administrative claims database. Post-operative
opioid use for one year post-operatively was assessed using the
rates of monthly repeat prescription. These were then compared between
patients with and without a specific variable of interest and with
those of patients who had undergone TKA and THA.Aims

Introduction
Methodology
To describe the longitudinal trends in patients with obesity and Metabolic Syndrome (MetS) undergoing TKA and the associated impact on complications and lengths of hospital stay. We identified patients who underwent primary TKA between 2006 – 2017 within the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. We recorded patient demographics, length of stay (LOS), and 30-day major and minor complications. We labelled those with an obese Body Mass Index (BMI ≥ 30), hypertension, and diabetes as having MetS. We evaluated mean BMI, LOS, and 30-day complication rates in all patients, obese patients, and those with MetS from 2006-2017. We used multivariable regression to evaluate the trends in BMI, complications, and LOS over time in all patients and those with MetS, and the effect of BMI and MetS on complication rates and LOS, stratified by year. 270,846 patients underwent primary TKA at hospitals participating in the NSQIP database. 63.71% of patients were obese (n = 172,333), 15.21% were morbidly obese (n = 41,130), and 12.37% met criteria for MetS (n = 33,470). Mean BMI in TKA patients increased at a rate of 0.03 per year (0.02-0.05; p < 0 .0001). Despite this, the rate of adverse events in obese patients decreased: major complications by an odds ratio (OR) of 0.94 (0.93-0.96; p < 0 .0001) and minor complications by 0.94 (0.93-0.95; p < 0 .001). LOS also decreased over time at an average rate of −0.058 days per year (-0.059 to −0.057; p < 0 .0001). The proportion of patients with MetS did not increase, however similar improvements in major complications (OR 0.94 [0.91-0.97] p < 0 .0001), minor complications (OR 0.97 [0.94-1.00]; p < 0 .0330), and LOS (mean −0.055 [-0.056 to −0.054] p < 0 .0001) were found. In morbidly obese patients (BMI ≥ 40), there was a decreased proportion per year (OR 0.989 [0.98-0.994] p < 0 .0001). Factors specifically associated with major complications in obese patients included COPD (OR 1.75 [1.55-2.00] p < 0.0001) and diabetes (OR 1.10 [1.02-1.1] p = 0.017). Hypertension (OR 1.12 [1.03-1.21] p = 0.0079) was associated with minor complications. Similarly, in patients with MetS, major complications were associated with COPD (OR 1.72 [1.35-2.18] p < 0.0001). Neuraxial anesthesia was associated with a lower risk for major complications in the obese cohort (OR 0.87 [0.81-0.92] p < 0.0001). BMI ≥ 40 was associated with a greater risk for minor complications (OR 1.37 [1.26-1.50] p < 0.0001), major complications (1.11 [1.02-1.21] p = 0.015), and increased LOS (+0.08 days [0.07-0.09] p < 0.0001). Mean BMI in patients undergoing primary TKA increased from 2006 - 2017. MetS comorbidities such as diabetes and hypertension elevated the risk for complications in obese patients. COPD contributed to higher rates of major complications. The obesity-specific risk reduction with spinal anesthesia suggests an improved post-anesthetic clinical course in obese patients with pre-existing pulmonary pathology. Encouragingly, the overall rates of complications and LOS in patients with obesity and MetS exhibited a longitudinal decline. This finding may be related to the decreased proportion of patients with BMI ≥ 40 treated over the same period, possibly the result of quality improvement initiatives aimed at delaying high-risk surgery in morbidly obese patients until healthy weight loss is achieved. These findings may also reflect increased awareness and improved management of these patients and their elevated risk profiles.
The aim of this study was to examine trends in the management of fractures of the distal radius in Ireland over a ten-year period, and to determine if there were any changes in response to the English Distal Radius Acute Fracture Fixation Trial (DRAFFT).

Dual mobility (DM) total hip arthroplasty (THA) prostheses are designed to increase stability. In the setting of primary and revision THA, DM THA are used most frequently for dysplasia and instability diagnoses, respectively. As the use of DM THA continues to increase, with 8,031 cases logged in the American Joint Replacement Registry from 2012–2018, characterizing Under IRB-approved implant retrieval protocol, 43 DM THA systems from 41 patients were included. Each DM THA component was macroscopically examined for standard damage modes. Clinically-relevant data, including patient demographics and surgical elements, were collected from medical records. Fretting and corrosion damage grading is planned, according to the Goldberg Introduction
Methods
The purpose of this study was to analyze trends in the surgical management of ON in recent years. Specifically, we evaluated the annual prevalences of: 1) joint preserving procedures (osteotomies and core decompression/grafts) and 2) joint non-preserving procedures (total hip arthroplasties [THAs], revision THAs, partial THAs) for the treatment of osteonecrosis of the femoral head (ONFH) between 2009 and 2016. A total of 406,239 ONFH patients who were treated between 2009 and 2016 were identified from a nationwide database. Treatment procedures were extracted using ICD-9-CM and ICD-10-CM procedure codes. Annual rates of each of the above procedures were calculated and the trends in the procedure types were also evaluated. Chi-square tests were performed to compare the annual prevalence of each procedure. The mean annual prevalence over the 8-year study period was calculated for each procedure.Introduction
Background
Bundled Payments (BP) were a revolutionary new experiment for CMS that tested whether risk sharing for an episode of care would improve quality and reduce costs. The initial success of BP accelerated their growth as evidence by the launch of both mandatory and commercial bundles. Success in BP is dependent on the target price and the opportunity to reduce avoidable costs during the episode of care. There is concern that the aggressive target pricing methodology in the new model (BPCI-Advanced) penalizes high performing groups that already achieved low episode costs through prior experience and investment in BP. We hypothesize that this methodology incorporates unsustainable downward trends on target prices to a point beyond reasonableness for efficient groups to reduce additional costs and will lead to a large percentage of groups opting out of BPCI-A in favor of a return to fee for service (FFS) reimbursement. Using CMS data, we compared the target price factors for hospitals that participated in both BPCI classic (2013 –2018) and BPCI Advanced (beginning 10/2018), referred to as “legacy hospitals”, with hospitals that only participated in BPCI Advanced (beginning 10/2018). With the rebasing of BPCI-A target prices in Jan 2020 and the opportunity for participants to drop out of individual episode types or the program all together, we compared the retention of episode types that hospitals initially enrolled at the onset of BPCI-A with the current enrollment in 2020. Locally, we analyzed the BPCI-A target price factors across hospitals for a large orthopaedic practice that participated in BPCI Classic and the impact it had on the financial incentive/disincentive to remain in the lower extremity joint replacement episode type in 2020.Introduction

Dual mobility bearings are an attractive treatment option to obtain hip stability during challenging primary and revision total hip arthroplasty (THA) cases. Despite growing enthusiasm in the United States, long-term results of modern dual mobility implants are lacking. The purpose of this study is to analyze data submitted to the American Joint Replacement Registry (AJRR) to characterize utilization trends of dual mobility bearings in the United States. All primary and revision THA procedures reported to AJRR from 2012–2018 were analyzed. Patients of all ages were included and subdivided into dual mobility and traditional bearing surface cohorts. Independent variables included patient demographics, geographic region, hospital size, and teaching affiliation. Associations were determined by chi-square analysis and a logistic regression was performed to assess the association between dual mobility and independent variables.Background
Methods
Fractures of the femoral neck occurring outside the capsule of the hip joint are assumed to have an intact blood supply and hence their conventional management is by fixation rather than arthroplasty. The dynamic hip screw and its variants have been used over many years to fix such fractures but have inherent vulnerabilities; they require an intact lateral femoral cortex, confer a relatively long moment arm to the redistribution of body weight and may cause a stress riser due to the plate with which they are fixed to the femur. Intramedullary devices for fixation of proximal femoral fractures have a shorter moment arm, can be distally locked with reduced perforation of the femoral cortex and are believed to be inherently more stable. For these reasons, a number of surgeons believe them to be superior to the DHS for all extracapsular fractures and their use is now widespread. In this study, we present the usage trends of both devices in extracapsular fractures over the last five years and set these results in the context of patient demographics. Our departmental electronic patient management system was used to identify all patients undergoing surgery coded as either DHS or its variants or intramedullary fixation of hip fracture. The patients’ age, sex and American Society of Anaesthesiologists grading were recorded. Comparison between groups was made using appropriate tests in SPSS.Background

Spondylodiscitis and vertebral osteomyelitis can lead to long-term sequelae if not diagnosed and treated promptly and appropriately. The Royal National Orthopaedic Hospital (RNOH) has devised a new spinal infection referral system within the UK that allows cases to be discussed in a specialist multi-disciplinary (MDT) forum. National guidelines were devised in 2013 to help guide treatment, which recommends both tissue biopsies from the affected region and a MRI of the entire spine. The aims of this study were to assess the current treatment and referral practices and compare them with the set guidelines. It is hypothesised that a high percentage of patients are started on antibiotics without a biopsy or a positive set of blood cultures, a low percentage of patients are referred without undergoing a MRI of the full spine and that there is a long delay in referral to the MDT. A retrospective case study analysis was carried out on all spinal infection referrals received by the Royal National Orthopaedic Hospital over a 2-year period (2014–16), using the standards set by the current national guidelines. Clinical features, haematology results, imaging, biopsy results, treatment and outcome were all reviewed. Three key areas were addressed; whether antibiotics were commenced before positive cultures or biopsy, whether a MRI of the entire spine was performed and the time taken for referral from the onset of symptoms.Aim

In Northumbria hip fractures have a 5-year mortality of 68%. To analyse 5-year mortality in distal femur fractures in the Northumbrian NHS trust, and identify risk factors for mortality. To compare the results to literature standards and Northumbrian hip fracture data.Background
Objectives
Patellar resurfacing is performed in more than 90% of primary total knee arthroplasties (TKAs) in the United States, yet far fewer patellae are resurfaced internationally. Multiple randomized controlled trials have shown decreased revision rates in patients with resurfaced patellas (RP) vs. non-resurfaced (NR). However, most of these studies showed no difference in patient satisfaction, anterior knee pain, or knee society scores. (Figure 1) Given uncertain benefits, the purpose of this study was to determine if the rates of patellar resurfacing have changed over the past 10 years worldwide. Data was obtained via direct correspondence with registry administrators or abstracted from the annual reports of six national joint registries: Australia, Denmark, England, New Zealand, Norway, and Sweden. Rates of patellar resurfacing between 2003 and 2013 were collected. Where data was available, subgroup analysis was performed to examine revision rates among RP and NR TKAs.Introduction
Methods
The treatment of osteochondral lesions and osteoarthritis
remains an ongoing clinical challenge in orthopaedics. This review
examines the current research in the fields of cartilage regeneration,
osteochondral defect treatment, and biological joint resurfacing, and
reports on the results of clinical and pre-clinical studies. We
also report on novel treatment strategies and discuss their potential
promise or pitfalls. Current focus involves the use of a scaffold
providing mechanical support with the addition of chondrocytes or mesenchymal
stem cells (MSCs), or the use of cell homing to differentiate the
organism’s own endogenous cell sources into cartilage. This method
is usually performed with scaffolds that have been coated with a
chemotactic agent or with structures that support the sustained
release of growth factors or other chondroinductive agents. We also
discuss unique methods and designs for cell homing and scaffold
production, and improvements in biological joint resurfacing. There
have been a number of exciting new studies and techniques developed
that aim to repair or restore osteochondral lesions and to treat
larger defects or the entire articular surface. The concept of a
biological total joint replacement appears to have much potential. Cite this article:
The advent of CT based 3D preoperative planning software for reverse total shoulder arthroplasty (RTSA) provides surgeons with more data than ever before to prepare for a case. Interestingly, as the usage of such software has increased, further questions have appeared over the optimal way to plan and place a glenoid implant for RTSA. In this study, a survey of shoulder specialists from the American Shoulder and Elbow Society (ASES) was conducted to examine thought patterns in current RTSA implant selection and placement. 172 ASES members completed an 18-question survey on their thought process for how they select and place a RTSA glenoid implant. Data was collected using a custom online Survey Monkey survey. Surgeon answers were split into two cohorts based on number of arthroplasties performed per year: between 0–75 was considered low volume (LV), and between 75–200+ was considered high volume (HV). Data was analyzed for each cohort to examine differences in thought patterns, implant selection, and implant placement.INTRODUCTION

3D preoperative planning software for anatomic total shoulder arthroplasty (ATSA) provides surgeons with increased ability to visualize complex joint relationships and deformities. Interestingly, the advent of such software has seemed to create less of a consensus on the optimal way to plan an ATSA rather than more. In this study, a survey of shoulder specialists from the American Shoulder and Elbow Society (ASES) was conducted to examine thought patterns in current ATSA implant selection and placement. 172 ASES members completed an 18-question survey on their thought process for how they select and place an ATSA glenoid implant.

METHODS
Hip dysplasia represents a wide spectrum of disease, and interest in the treatment of the disorder has increased with the development of newer surgical techniques and a greater understanding of young adult hip disorders. National hospital episode statistics (HES) were studied from 1999 to 2010. This data remains the current best source of information on surgical procedures outside of dedicated registries. Age stratified data was analysed for 7 separately coded operations for the treatment of hip dysplasia. Overall in the paediatric population there were 898 procedures in 2010 compared to 793 procedures in 2000, but with no detectable trend across that period. Equally, there were no great fluctuations in the small numbers of arthroplasty procedures recorded in either the paediatric or adult populations. There was, however, a clear increase in surgery being performed in adult patients. 210 primary pelvic osteotomies were performed in 2010, compared with only 77 in 2000, with a noticeable increase from 2005 onwards. A similar trend in other extra-articular procedures is seen, rising from 2 to 55 per year over the period studied. Overall, the level of surgical intervention has steadily risen from 104 procedures in 2000 to 422 in 2010, representing a fourfold rise in the number of operations being performed for hip dysplasia in the adult population over an 11 year period. The reasons for this are unclear. It may reflect improvements in the ability to diagnose and intervene earlier to prevent disease progression, but further research is also needed to better define the aetiology underlying these cases that present to the hip surgeon later in life.
With increasing emphasis on evidence-based medicine in healthcare, there is global increase in proportion of Level-1 and -2 articles in PUBMED. This study shows the trend of orthopaedic publications from different countries in comparison to other specialties. New medical knowledge is expected to improve health through change in existing practices. Articles need to convince readers of the validity of conclusions in order to bring about a change in practice. The last few decades have witnessed an increasing interest in critical appraisal of research aimed at assessing the ‘quality’ of evidence, a trend towards ‘Evidence Based Medicine’. Whether orthopaedic publications are also becoming more evidence-based has hitherto not been reported. This study aimed to compare the trend of publications originating from orthopaedic services versus other specialties, across different countries, with respect to major categories of levels of evidence.Summary Statement
Introduction
There has been considerable activity in the past year as a result of the Justice Department Investigation into the medical device industry. There has been an over reaction by many which may negatively impact future research, development and reporting of clinical outcomes. This paper will review some of these activities. A review of professional standards and guidelines has been conducted looking at health care compliance issues as they related to commercial relationships, professional medical societies, individual surgeons, and health care workers with specific focus on disclosure. Within any important issue, there are always aspects no one wishes to discuss: conflict of interest. Perception of a conflict of interest is often enough to bring about a review of activity. Overreaction has occurred as a result of government intervention into the medical device industry. Continuing medical education, professional societies by-laws, clinical/surgical publications, medical/legal exposure, product research, development and industry marketing activities have all been impacted. When professionals fail to provide a proper review process on standards and guidelines on ethical behavior they set themselves up for government oversight and restrictions on their behavior. Be informed and disclose. Know what, when and how to disclose. Protect yourself, no one else will.
This study aims to identify recent trends in discharge disposition following bilateral total knee arthroplasty (TKA) as well as factors that predispose patients to enter inpatient rehabilitation facilities (IRF) or skilled nursing facilities (SNF) versus home-rehabilitation (HR). The goal was to identify risk factors that predispose prolonged hospital stays and identify changes in management over time that may be responsible for decreased length of stay (LOS) and a HR program. A retrospective cohort study design was used to collect and analyze clinical and demographic data for 404 consecutive bilateral primary total knee arthroplasty (TKA) procedures. Patients who underwent elective primary bilateral total knee arthroplasty from 2011 to 2016 were identified from hospital records at a single institution. Clinical and demographic data including sex, age, and disposition were analyzedBACKGROUND
METHODS
Spinal cord injury is an inevitable but rare occurrence in sports. Identifying trends and working to minimise risk is an integral part of sports management. All patients suffering a spinal cord injury in Scotland will be transferred to the Queen Elizabeth National Spinal Injuries Unit (QENSIU). Our records give an accurate account of trends in spinal cord injury. This study details the number of spinal cord injuries caused by sports and leisure pursuits in Scotland since 1992. 1451 patients have suffered a spinal cord injury in Scotland from 1992-2008. 142 (9.8%) arose from injuries during sport. The average age at injury was 32, and patients were predominantly male (91%). The commonest cause was diving (40, 28%) followed by cycling (29, 20%) climbing and hillwalking (15, 11%) and rugby union (12, 8%). Smaller numbers were seen in horse-riding (11), aerial sports (6), motor sports (6), snow sports (5), and football (5). Overall, there was evidence of an increasing trend in the number and severity of injuries in rugby and cycling. The number of spinal injuries, caused by diving, rugby and cycling remains disproportionally high and the increasing trends identified merit further investigation.
Joint arthroplasties may be associated with a blood loss, which necessitates transfusion. Especially, hip arthroplasties are highly associate with transfusion to compensate perioperative bleeding. Orthopaedic surgeons and patients have increasing concerns regarding complications of blood transfusions. Although various methods to reduce transfusions have been attempted in TJA, a high percentage of patients require a transfusion during and after the procedures. The purposes of this study were to evaluate the trends of the transfusion(transfusion rates, transfusion amounts, economic burden) in hip arthroplasties, using nationwide data from the National Health Insurance Service (NHIS). We used data from nationwide claims database of Health Insurance Review Assessment Service (HIRA). The data managed by the NHIS were used to identify the 161,934 hip arthroplasties by 3 categories including bipolar hemiarthroplasty(BH), total hip arthroplasty(THA), and revision arthroplasty(RA) from 2007 to 2015. These 3 categories were classified using the operation code recorded in the requisition data of NHIS. The transfusion rates, transfusion amounts, proportion of transfusion, cost of each type of operation was investigated and stratified by age, gender, hospital type, and area in hip arthroplasties. The proportion of transfusion about whole blood, red blood cell, fresh frozen plasma, platelet, was also evaluated in hip arthroplasties.Aims
Patients and methods
Due to improvement in overall prosthesis designs and surgical methods, there have been increasing numbers of total ankle arthroplasty performed with encouraging intermediate results. While European registries have been able to perform long term follow-ups and analysis on total ankle arthroplasty patients, majority of the US studies have been based on experiences at a single institution. There is currently limited data on the recent trends of total ankle arthroplasty. The purpose of our study is to evaluate the in-patient demographics, complications and readmission rate in patients after total ankle arthroplasty at academic medical centers in United States. We queried the University Healthsystems Consortium (UHC) administrative database from 2007 to 2011 for patients who underwent total ankle arthrolasty by ICD-9 procedure code 81.56. A descriptive analysis of demographics was performed, followed by a similar analysis of patient clinical benchmarks, including hospital length of stay, hospital direct cost, in-hospital mortality, and 30-day readmission rates.Introduction:
Patients & Methods:
The World Health Organisation (WHO) has recently identified musculoskeletal care as a major global health issue in the developing world. However, little is known about the quality and trends of orthopaedic research in resource-poor settings. The purpose of this study was to perform a systematic review of orthopaedic research in low-income countries (LIC). The primary objective was to determine the quality and publication parameters of studies performed in LIC. Secondary objectives sought to provide recommendations for successful strategies to implement research endeavors in LIC. A systematic review of the literature was performed by searching MEDLINE (1966-November 2014), EMBASE and the Cochrane Library to identify peer-reviewed orthopaedic research conducted in LICs. The PRISMA guidelines for performing a systematic review were followed. LIC were defined by the WHO and by the World Bank as countries with gross national income per capita equal or less than 1045US$. Inclusion criteria were (1) studies performed in a LIC, (2) conducted on patients afflicted by an orthopaedic condition, and (3) evaluated either an orthopaedic intervention or outcome. The Oxford Centre for Evidence-Based Medicine Levels of Evidence, and Grading of Recommendations Assessment, Development and Evaluation (GRADE) were used to objectively rate the overall methodological quality of each study. Additional data collected from these studies included the publication year, journal demographics, orthopaedic subspecialty and authors' country of origin. A total of 1,809 articles were screened and 277 studies met our inclusion criteria. Eighty-eight percent of studies conducted in LIC were of lower quality evidence according to the GRADE score and consisted mostly of small case series or case reports. Bangladesh and Nepal were the only two LIC with national journals and produced the highest level of research evidence. Foreign researchers produced over 70% of the studies with no collaboration with local LIC researchers. The most common subspecialties were trauma (42%) and paediatrics (14%). The 3 most frequent countries where the research originated were the United States (42%), United Kingdom (11%), and Canada (8%). The 3 most common locations where research was conducted were Haiti (18%), Afghanistan (14%), and Malawi (7%). The majority of orthopaedic studies conducted in LIC were of lower quality and performed by foreign researchers with little local collaboration. In order to promote the development of global orthopaedic surgery and research in LIC, we recommend (1) improving the collaboration between researchers in developed and LIC, (2) promoting the teaching of higher-quality and more rigorous research methodology through shared partnerships, (3) improving the capacity of orthopaedic research in developing nations through national peer-reviewed journals, and (4) dedicated subsections in international orthopaedic journals to global healthcare research.
The bearing surface is the critical element in determining the longevity of a total hip arthroplasty. Over the past decade problems associated with bearing surfaces and modular femoral tapers have had an impact on surgeon selection of both acetabular liners and modular femoral heads. The purpose of this study was to analyse THA bearing surface trends from 2007 through 2014 using a large national database. A retrospective review of the Nationwide Inpatient Sample (NIS) database was conducted from 2007 to 2014. All patients who underwent a primary THA were identified using International Classification of Diseases, 9th edition (ICD-9) procedure codes. Bearing surface data was extracted by identifying patients with ICD-9 procedure modifier codes. Patient and hospital characteristics were recorded for each patient. Descriptive statistics were employed to characterise bearing surface trends for the following bearing surfaces: metal on polyethylene (MoP); ceramic on polyethylene (CoP); ceramic on ceramic (CoC) and metal on metal (MoM). Univariate analysis was performed to identify differences between the bearing surface groups. During the study period, 2,460,640 primary THA discharges were identified, of which 1,059,825 (43.1%) had bearing surface data available for further analysis. The breakdown of the bearing surfaces used for these THAs were as follows: MoP − 49.1% (496,713); CoP − 29.1% (307,907); CoC − 4.2% (44,823); and MoM − 19.9% (210,381). MoM utilization peaked in 2008 with 51,033 cases representing 40.1% of THAs implanted that year. The usage steadily declined and by 2014 there were only 6,600 MoM cases representing only 4.0% of the THAs. From 2007 to 2014, the use of CoP bearing surfaces increased from 11,482 discharges (11.1% of cases) in 2007, to 83,300 discharges (50.8% of cases) in 2014. CoP utilization surpassed MoP in 2014. MoP accounted for 54.7% of discharges in 2011 and just 42.1% in 2014. During the study period, MoM bearing surface usage declined precipitously, while CoP surpassed MoP as the most prevalent bearing surface used in total hip arthroplasty patients. These changes in bearing surface usage over time were clearly influenced by concerns regarding high failure rates associated with MoM articulations and reports of taper corrosion associated with modular metal femoral heads.
Prospectively collected data is an important source of information subjected to change over time. What surgeons were doing in 1999 might not be the case anymore in 2016 and this change in time also applies to a number of factors related to the performance and outcome of total hip replacement. We evaluated the evolution of factors related to the patient, the surgical procedure, socio-economy and various outcome parameters after merging the databases of the Swedish Hip Arthroplasty Register, Statistics Sweden and the National Board of Health and Welfare. Data on 193,253 THRs (164,113 patients) operated between 1999 and 2012 were merged with databases including general information about the Swedish population and about hospital care. We studied the evolution of surgical volume, patient demographics, socio-economic factors, surgical factors, length of stay, mortality rate, adverse events, re-operation and revision rates and PROMs. Most patients were operated because of primary osteoarthritis and this share increased further during the period at the expense of decreasing number of patients with inflammatory OA and hip fracture. Comorbidity and ASA scores increased for each year. The share of all cemented implants has dropped from 92% to 68% with a corresponding increase of all uncemented from 2% to 16%. Length of stay decreased with about 50 percent to 4.5 days in 2012. The 30- and 90-day mortality rate dropped to 0.4% and 0.7%. Re-operation and revision rates at 2 years were lower in the more recent years. The postoperative PROMs are improving despite the preoperative pain scores getting worse. Even in Sweden, always been considered as a very conservative country with regards to hip replacement surgery, the demographics of the patients, the comorbidities and the primary diagnosis for surgery are changing. Despite these changes the outcomes like mortality, re-operations, revisions and PROMs are improving.
Chondral injury has become one of the most difficult problems to solve in orthopaedics. This pathology is very common: Curl et al. founded an incidence of 63% of chondral lesions (2.7 lesions for knee in 31,156 knee arthroscopies) with a 20% rate of lesions of grade IV of Outerbridge. During the past few decades many techniques were developed: with these techniques the lesion is just reparied with the formation of fibro-cartilage tissue with biochemical and bioelastic characteristics very different from the hyaline cartilage tissue. Microfracture technique : This technique, proposed by Steadman et al., utilises hand-drills to create numerous perforations in the subchondral bone at 3–4 mm apart. Indications for this techniques are lesions from 0.5 to 2 cm2 with an outlined border in patients with low functional demand. Osteochondral autograft transplantation (OATS, mosaicplasty): Osteochondral autograft transplantation is indicated for isolated lesions from 1 to 3 cm2 or in OCD. Outerbridge et al., in a study of 10 patients with 6.5 years of follow-up, achieved good functional results in all pateints treated with this technique. Autologous chondrocyte implant: ACI, reported for the first time by Peterson and colleagues in 1994, is advised for young or middle-aged, active patients with a single painful chondral injury (3–4 grade of Outerbridge scale), starting from more than 2 cm2. They. reported good results in the treatment of chondral lesion with a long follow-up (2–10 years). New tissue engeneering techniques with the use of biomaterial derived from hyaluronic acid provides ideal support to the culture and proliferation of chondrocytes, allowing at the same time arthroscopic implant. Today there are many options in the treatment of chondral lesions, but no one technique can be considered the gold standard. ACI in arthroscopy is a more promising technique in the treatment of the chondral lesions, but the indications are still too restricted.
The exact prevalence of scoliosis remains unknown however it appears to be stable over time. In contrast the surgical management of spinal deformity has evolved considerably. In the UK this can be observed by examining recorded hospital statistics. Specifically the volume of procedures undertaken and preferred technique to correct deformity can be analysed and trends captured providing a comprehensive picture of changing UK practice. Annual data tables from 2000 to 2013 were downloaded from the health information and social care UK website which contains Hospital Episode Statistics (HES) data online. Numbers of completed consultant episodes for the four character primary procedure codes V41.1 (posterior attachment of correctional instrument to spine), V41.2 (anterior attachment of correctional instrument to spine), V41.4 (Anterior and posterior attachment of correctional instrument to spine), V41.8 and V41.9 (other specified and other non-specified instrumental correction of spinal deformity respectively) as main procedure where recorded. The total number of attachment of correctional instrument procedures listed as main procedure has increased significantly. The increase consists of higher numbers of posterior attachment procedures over this time from 352 in 2011–2012 to 1967 in 2012–2013 with data demonstrating a year on year increase to 2009–2010 before plateauing. Unspecified and other specified instrumental correctional spinal procedures have also contributed to the overall rise increasing from 206 in 2000–2001 to 447 in 2012–2013. Anterior attachment procedures listed as the main procedure are currently declining in number from a peak of 230 in 2005–2006 to 89 in 2012–2013. Combined posterior and anterior attachment procedures have also decreased marginally from 27 in 2009–2010 to 19 in 2012–2013. Unfortunately combined anterior and posterior procedures were not uniquely coded until 2009–2010. There is also some inherent variability in accuracy of coding which may distort HES data. Despite these limitations these results are likely to represent genuine changes in practice for the surgical correction of spinal deformity over the time period examined.
Treatment of acute Achilles tendon rupture is based on obtaining and maintaining apposition of the ruptured tendon ends. Surgical treatment utilises direct suture repair to produce this objective, while conservative or non-surgical management achieves the same effect of closing the tendon gap by immobilisation of the ankle joint in a plantar flexed position within a plaster cast or POP. There is still variability in the conservative treatment practices and protocols of acute Achilles tendon ruptures. The purpose of this study is to examine the current practice trends in the treatment of Achilles tendon ruptures amongst orthopaedic surgeons in the UK. A postal questionnaire was sent to 221 orthopaedic consultants in 25 NHS hospitals in the Greater London area in June 2010. Type and duration of immobilisation were considered along with the specifics of the regime used. Ninety questionnaires were returned giving a 41% response rate. Conservative treatment methods were used by 72% of respondents. A below knee plaster was the top choice of immobilisation (83%) within this group. The mean period of immobilisation was 9.2 weeks (Range 4-36). Weight bearing was allowed at a mean of 5.3 weeks (range 0-12) The specific regime used by consultants was quite heterogeneous across the group, however the most used immobilisation regimen was a below knee plaster in equinus with 3 weekly serial plaster changes to a neutral position, for a total of nine weeks. A heel raise after plaster removal was favoured by 73% of respondents used for a mean period of 6.4 weeks (Range 2-36). In response to ultrasound use as a diagnostic tool, 42.4% of respondents would never use it, 7.6% would use it routinely, while 50% would use it only according to the clinical situation. Comparison of foot and ankle specialists with non-specialists did not reveal a significant difference in practice in duration of immobilisation or time to bearing weight. Conservative management remains a widely practice option in the treatment of Achilles tendon ruptures. Although there are available a number of modern walking aids, the concept of functional brace immobilisation is not as widely used as below knee plaster cast immobilisation, which remains a popular choice amongst orthopaedic surgeons today. There is still no consensus on the ideal immobilisation regimen although a below knee plaster in equinus with serial changes for a total of nine weeks is the most frequently used choice. Further randomised controlled trials are required to establish the optimal treatment strategy for conservative management of Achilles tendon rupture.
Epidemiological figures reflect those of other studies. The male: female ratio was 1.4: 1, most common age at diagnosis was 16 – 18 and the most common site of tumor was the distal femur, 71% of tumors occurred at the knee. 5 year and median survival were 30% and 26 months for the entire period. 5 year survival was found to have improved from 21% between 1933–1959 to 62% in 1990 – 1999. On univariate analysis the most significant factor influencing outcome was use of chemotherapy in treatment (p<
0.00005). On multivariate analysis, date of diagnosis had most influence on the hazard ratio, the greatest difference being found between diagnoses pre and post – 1980. Site of tumor was also found to be a significant factor (p=0.044). The survival from Osteosarcoma in Scotland in recent years was found to be no worse than the rest of the UK as had previously been suggested.
Infection following hip arthroplasty although uncommon can have devastating outcomes. Obesity, defined as a BMI of ≥ 30, is a risk factor for infection in this population. Coagulase negative staphylococcus aureus (CNS) is the commonest causative organism isolated from infected arthroplasties. This study was performed to determine if there has been a change in the causative organisms isolated from infected hip arthroplasties and to see if there is a difference in obese patients. Data on all deep infection following primary and revision hips was obtained from the surgical site infection register from April 1998 to Nov 2007. Case notes were reviewed retrospectively. There were 49 patients with 51 infected arthroplasties; 25 infected Primary THAs and 26 infected Revision THAs. We found a female preponderance in the infected primary and revision THAs (n=30). 63.2% of all patients had a BMI of ≥ 30, compared to only 34.7% of the non infected population (p<
0.0001). Over the period studied, CNS was the most common organism isolated (56.8%) followed by mixed organisms (37.2%) and staphylococcus aureus (25.4%). Multiple organisms were found exclusively in obese patients. In more than half of cases the causative organisms were resistant to more than two antibiotics. This study shows that over the last 10 years, CNS continues to be the most frequently isolated organism in infected hip arthroplasties. Multiple organisms with multiple antibiotic resistances are common in obese patients. On this basis we recommend that combination antibiotic therapy should be considered in obese patients.
This study sought to determine the post-operative management of spinal patients in the UK, and to determine if uniformity exists between surgeons and if there is any published evidence for this practice. A reply-paid questionnaire was sent to members of the British Association of Spinal Surgeons and the Society for Back Pain Research. The questionnaire documented the surgeon’s experience, where they work, their operative population, the types of spinal surgery performed, and whether they have a routine for post-operative management or any written instructions for patients concerning post operative management. It also asked about the nature and duration of professionally supervised rehabilitation. Of the 89 questionnaires distributed, 63 (71%) were returned, of which 51 could be used in the analysis. The 12 not used were either completed incorrectly, had missing data or the surgeon had since retired. The replies demonstrated wide variation: only 35% of surgeons provide their patients with written post-operative instructions; there was limited referral to physiotherapy, with only 45% referring to a physiotherapist (for an average of 1.8 sessions); only a modest fraction of surgeons advocated the use of a post-operative corset (18%), others restricting sitting or encouraging bed rest; and a range of recommendations regarding return to work. There was also only a limited correlation between restrictions on sitting and recommendations about return to sedentary work or driving (Spearman r=0.08 and 0.36, respectively). In summary, although individual surgeons may be certain of their practice, the overall variation indicates ongoing uncertainty across the profession. This was further substantiated by our literature search, which revealed limited evidence for current practices, and a paucity of research into postoperative management.
Alternative bearing surfaces has been introduced to reduce wear debris-induced osteolysis after total hip arthroplasty (THA) and offered favorable results. Large population-based data for total joint surgery permit timely recognition of adverse results and prediction of events in the future. The purpose of this study was to present the epidemiology and national trends of bearing surface usage in primary total hip arthroplasty (THA) in Korea using nationwide database. A total of 30,881 THAs were analyzed using the Korean Health Insurance Review and Assessment Service database for 2007 through 2011. Bearing surfaces were sub-grouped according to device code for national health insurance claims and consisted of ceramic-on-ceramic (CoC), metal-on-polyethylene (MoP), ceramic-on-polyethylene (CoP), and metal-on-metal (MoM). The prevalence of each type of bearing surface was calculated and stratified by age, gender, hospital type, primary payer, and procedure volume of each hospital. The number of primary THAs increased by 25.2% from 5,484 in 2007 to 6,866 in 2011. The average age of the entire study population was 58.1 years, and 53.5% were male [Table 1]. CoC was the most commonly used bearing surface (76.7%), followed by MoP (11.9%), CoP (7.3%), and MoM (4.1%). The distribution of bearing surfaces was identical to that in the general population regardless of age, gender, hospital type, and primary payer [Table 2]. The mean age of patients that received hard-on-hard bearing surfaces (CoC and MoM) was significantly younger than that of patients receiving hard-on-soft bearing surfaces (CoP and MoP) (56.9 years vs. 62.6 years). During the study period, 55.1% of THAs that used a hard-on-hard bearing surface were performed in males, while 53.0% of THAs that used a hard-on-soft bearing surface were performed in females. The order of prevalence of bearing surfaces was identical in low- and medium-volume hospitals (CoC was first, MoP was second, CoP was third, and MoM was fourth). The mean hospital charges did not differ according to the bearing surface used, with the exception of CoP, which was associated with a lower mean hospital charge. There were no changes in the distribution of bearing surfaces in each year between 2007 and 2011. Overall, the percentage of THAs that used CoC bearing surfaces increased substantially from 71.6% in 2007 to 81.4% in 2011, while the percentage that used CoP, MoP, and MoM decreased significantly [Fig. 1]. One of the reasons for the dominant usage of hard-on-hard bearing surfaces may be that the principal diagnosis of primary THAs and the patient age group distribution in Korea differ from those in other countries. The most common indication for primary THA is osteonecrosis of the femoral head in Korea. In contrast, the majority of primary THAs are performed for osteoarthritis in Western countries. The choice of bearing surface may be affected by many factors, including the nation's medical delivery system, payment type, disease pattern, and age distribution of patients that undergo THA. In future, the results of a large-scale nationwide study on primary THAs using CoC bearing surfaces in Korea will be reported.
There has been significant advancement in the principles and practices of Tissue Banking in Australia over the last two years. Those advances relate to scientific development, regulatory modulation and inter-relationships between both Federal and State governments. Licencing issues

We aim to present an 18 Month Review of one Surgeons Practice Involving 16 Patients with 3 or 4 part Fractures or 3 part Fracture-Dislocations of the Proximal Humerus in patients under 60 years of age. Management principles include anatomic reduction, internal fixation and early movement. The implants used in this series include: The PLANTAN PLATE from ATLANTECH The STRATEC 4.5 mm ANGLE BLADE PLATE The POLARUS NAIL and various small cannulated screw systems. 3 patients were treared with minimal fixation, 5 with the AO Bladeplate, 4 with the PLANTAN plate and 4 with the Polarus nail. Surgical Treatment, Radiographic and Clinical Outcomes will be reviewed. Anatomic considerations, surgical technique and outcomes will be discussed.
Inciting events leading to deep vein thrombosis occur primarily intraoperatively. Therefore, if at all possible, intervention should be performed at the time of the operative procedure. It has been demonstrated in hip replacement surgery that DVT is significantly reduced with epidural hypotensive anaesthesia, which may or not be augmented with intraoperative small doses of heparin (500–1000 units). Reduction of extreme limb position with occlusion of the femoral vein during hip replacement surgery reduces the stasis effect, which promotes clotting. In the hip, overall DVT rates have been reduced to 7% and proximal DVT rates to 2% using these intraoperative techniques. Mechanical devices work by a myriad of mechanisms: 1.) venous turbulence is created in valve pocket areas and this reduces clot formation; 2.) there is an increase release of endothelial relaxing factor (EDRF) which inhibits platelet aggregation; 3.) intermittent compression stimulates fibrinolysis by inducing release of urokinase and tissue plasminogen from the venous endothelium. Randomised trials have demonstrated a reduction in DVT to levels similar to pharmacologic agents (20–27%) without the risk of postoperative haemorrhage. However, compliance with use of these devices is crucia1, as a positive relationship has been demonstrated between time of use and DVT rates. Although plantar pump devices tend to be well tolerated with occasional complaints of foot and skin irritation, calf compression devices with or without sequential foot compression applying at least 50 mmHg of external pressure at a frequency of at least once per minute and an inflation rate of less than 1 second tend to be the ideal device for DVT prophylaxis.
This study aims to explore the trend in spine fusion surgery in Australia over the past 10 years and to explore the possible influence of health insurance status (private versus public) on the rate of surgery. Data pertaining to the rate of lumbar spine fusion from 1997 to 2006 were collected. Data on publicly performed procedures in NSW were obtained from Inpatient Statistics Collection of NSW Health, and data on privately performed procedures were obtained from Medicare Australia Statistics. Population data was obtained from the Australian Bureau of Statistics. Data on total hip and total knee arthroplasties performed were collected to provide a comparator. Health insurance coverage was also investigated to control for insurance status, this data was obtained from the Private Health Insurance Administration Council. There has been a slowly declining trend in the number of publicly performed spinal fusion procedures over the past 10 years, falling by 63% from 1997 to 2006 in NSW. In comparison, privately performed spinal fusion procedures have increased by 166% over the same 10 year period. Compared to spine fusion, the rates of total hip and total knee replacement procedures in the public sector of NSW have fallen by smaller proportions (58.9%% and 42.1%, respectively) over the same 10 year period. The increase in privately performed joint replacements has been less than that seen for spine fusion, with increases of 120% and 74%% for knee arthroplasties and hip arthroplasties, respectively. In 2006, spine fusion surgery was 10.8 times more likely to be done in the private sector than in the public sector, compared to corresponding figures of 4.2 times and 3.0 times for knee replacement and hip replacement, respectively. Our study has demonstrated that there is a disproportionately high rate of spine fusion procedures performed in the private sector. Possible explanations for this difference include: over servicing in the private sector, under servicing in the public sector, differences in medical referral patterns, surgeon and patient preferences, and financial incentives.
Distal radial fractures in the elderly population have been traditionally managed by closed techniques, primarily due to their poor bone quality and low functional demands. Since the introduction of the volar locking plate (VLP), which provides a good fixation in osteoporotic bones, there maybe an increased use of open reduction and internal fixation (ORIF) in the elderly population. We aimed to determine the changes in the management of these fractures in Scotland, and whether this differs between specialist regional centres and district general centres.Background

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. 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.Introduction

Ponseti first advocated his treatment for idiopathic clubfoot in the early 1950's. The method has only gained popularity and widespread use since the 1990's. Despite publications showing favourable results, there is little published data scrutinising the change in modes of talipes treatment. This study sought to define the trends in treatment for Idiopathic Clubfoot in Scotland over a twelve-year period (1997 – 2008). (i) A review was performed to identify the number of publications referencing the Ponseti method over the past 40 years. (ii) A structured questionnaire was sent to all Paediatric Orthopaedic practitioners in Scotland to ascertain the treatment methods used and over the time period. (iii) Data from the National Census for number of live births were combined with that obtained from the Scottish Morbidity Record (SMR01) for number of peritalar clubfoot surgeries performed over the study period. (iv) Similar data was also obtained for non-Talipes related peritalar surgeries, and data colleceted for the number of Tibialis Anterior transfer operations for this period. Clubfoot incidence data was measured indirectly by means of sample from the database of a tertiary referral Paediatric Orthopaedic Unit. Regression analysis was used to evaluate the trends over time. Review of the literature referencing the Ponseti method over the past 40 years showed an exponential increase from the late 1990's. The survey of Clubfoot management of Paediatric Orthopaedic Surgeons in Scotland showed a marked increase in use of the method over with this period. Over this period, the number of operations for clubfoot dropped substantially, from 55 releases in 1997 to 1 release in 2008. The linear equation estimated a decrease of approximately 5 surgical releases per year (R²= 0.87, p<0.05). In Scotland, most Tibialis Anterior transfers are performed at age 3years, the frequency of the procedure has increased in the latter half of the study period. In Scotland between 1997 and 2008, the number of peritalar (posterior, medial, posteromedial release) operations used in the primary treatment of idiopathic clubfoot has dropped substantially. This correlates with a marked increase in reference to the method within the literature and increased usage of the Ponseti technique by Paediatric Orthopaedic Consultants.
Robotic Assisted Arthroplasty (RAA) is increasingly proliferative in the international orthopaedic environment. Traditional bibliometric methods poorly assess the impact of surgical innovations such as robotic technology. Progressive Scholarly Acceptance (PSA) is a new model of bibliographic analysis which quantitatively evaluates the impact of robotic technology in the orthopaedic scientific community. A systematic literature search was conducted to retrieve all peer-reviewed, English language publications studying robotic assisted hip and knee arthroplasty between 1992 and 2017. Review articles were excluded. Articles were classified as either “initial investigations” or “refining studies” according to the PSA model, described by Schnurman and Kondziolka. The PSA end-point is defined as the point in time when the number of studies focussed on refining or improving a novel technique (RAA) outnumbers the number of initial studies assessing its efficacy.Introduction and aims

The Oxford Knee Score (OKS) is a valid and reliable self-administered patient questionnaire that enables assessment of the outcome following total knee replacement (TKR). There is as yet no literature on the behavioral trends of the OKS over time. Our aim is to present a retrospective audit of the OKS for patients who have undergone TKR during the past ten years. We retrospectively analysed 3276 OKS of patients who had a primary TKR and had been registered as part of a multi-surgeon, outcome-monitoring program at St. Helier hospital. The OKS was gathered pre-operatively and post-operatively by means of postal questionnaires at annual intervals. Patients were grouped as per their age at operation into four groups: 60, 61-70, 71- 80 and >80. A cross-sectional analysis of OKS at different time points was performed. The numbers of OKS available for analysis were 504 pre-operatively, 589 at one-year, 512 at two-year and gradually decreasing numbers with 87 knees ten-year post-operatively. There was as expected a significant decrease (improvement) of the OKS between pre-operative and one-year post-operative period and then reached a plateau. Beyond eight years, there is a gradual rise in the score (deterioration). The younger patients (60) showed a significant increase in their average OKS between one and five-years post-operatively. However beyond five years, they followed the trend of their older counterparts. When the twelve questions in the OKS were analysed, certain components revealed greater improvement (e.g. description of knee pain and limping) than others (e.g. night pain). The OKS is seen to plateau a year after TKR. According to the OKS the outcome of the TKR is not as good in the younger age group as compared to the older age group. Further investigation is required to ascertain the cause of this observed difference.
Primary total knee arthroplasty (TKA) is associated with perioperative bleeding, and some patients will require allogenic blood transfusion during their inpatient admission. While blood safety has improved in the last several decades, blood transfusion still carries significant complications and costs. Transfusion indications and alternative methods of blood conservation are being explored. However, there is limited nationally representative data on allogenic blood product utilization among TKA patients, and its associated outcomes and financial burden. The purpose of this study was to use a national administrative database to investigate the trends in utilization and outcomes (i.e. in-hospital mortality, length of stay, admission costs, acute complications) of allogenic blood transfusion in primary TKA patients. The Nationwide Inpatient Sample (NIS), the largest all-payer inpatient care database representing a 20% stratified sample of United States hospitals, was utilized. Primary TKA (ICD-9-CM 81.54) cases from 2000 to 2009 were retrospectively queried (n = 4,544,999; weighted national frequency). A total of 67,841 admissions were excluded (Figure 1). The remaining 4,477,158 cases were separated into two study cohorts: (1) patients transfused with allogenic blood products (red blood cells, platelets, serum) (n = 540,270) and (2) patients not transfused (n = 3,936,888). Multivariable regression and generalized estimating equations were used to examine the effect of transfusion on outcomes, adjusting for patient/hospital characteristics and comorbidity.Introduction:

Osteocondritis dissecans (OCD) is a relatively common cause of knee pain. Ideal treatment is still controversial. Aim of this exhibit is to describe the outcomes of 5 different surgical techniques in a series of 63 patients. 63patients (age 22.5±7.4 years) affected by OCD of the femoral condyle (45 medial and 17 lateral) were treated by either osteochondral autologous transplantation, autologous chondrocyte implantation with bone graft, biomimetic nanostructured osteochondral scaffold (Maioregen) implantation, bone-cartilage paste graft or bone marrow derived cells transplantation “one-step” technique. Patient evaluation included IKDC score, eq-vas score, X-Rays and MRI preoperatively and at follow-up. Global mean IKDC improved from pre-operative 40.1±14.6 to 77.2±21.3 (p<0.0005) at mean 5.3±4.7 years follow-up, while eq-vas improved from 51.7±17.0 to 83.5±18.3(p<0.0005). No influence of age, size of the lesion, length of follow-up and associated surgeries on the result was found. No differences were found between the results obtained with different surgeries except a slight tendency of better improvement in the result following autologous chondrocyte implantation (p<0.01). Control MRI evidenced a satisfactory repair of cartilaginous layer and subchondral bone. The techniques described were effective in providing good clinical and radiographic results in the treatment of OCD and confirmed the validity of autologous chondrocyte implantation over time. Newer techniques such as Maioregen implantation and “one-step” base on different rationales, the first relying on the characteristics of the scaffold and the second on the regenerative potential of mesenchymal cells. Both of them have the advantages to be minimally invasive surgeries and to require a single operation.
Postoperative pain following (Mobility TM) ankle arthroplasty (AA) is recognised problem. This study aimed to determine pattern of postoperative pain following Ankle arthroplasty (AA). In prospective observational study 135 patients who had (AA) and follow-up of 12–36 months were included. AOFAS ankle score, patients' satisfaction, SF36 and diagrammatic mapping of postoperative pain among other parameters were collected preoperatively and postoperatively at 3 months, 6 months and the annually. Patients with AOFAS of < 50 with postoperative ankle pain were examined in details.Background

The universal availability of CT scanners has led to lower thresholds for imaging despite significant financial costs and radiation exposure. We hypothesized that this recent trend increased the use of CT for upper limb articular fractures and led to more frequent operative management. A 5-year retrospective study (01/07/2005–30/06/2010) was performed on all adult patients with upper extremity articular fractures (AO: 1.1, 1.3, 2.1 and 2.3) admitted to a Level-1 Trauma Centre. Patients were identified from the institutions prospectively maintained AO classification database. A total of 1651 patients with 1735 upper extremity articular fractures were identified. 1131 (65%) fractures were operated on. 556 (32%) fractures had CT imaging, 429 (77%) of these had operative management. 289 (17%) patients had multiple injuries and 168 (10%) received a scan of at least 1 other body region. There was a gradual increase in CT use and operative management 1.1, 1.3 and 2.1 fractures. Operation rates for 2.3 fractures unchanged but CT imaging frequency declined. In patients younger than 55 years operative management remained stable at 71% throughout the 5-year period considering all four regions. Overall CT use was stable at 38%, however scan rates for distal radius decreased but for proximal forearm increased. The operative management of patients older than 55 years has increased significantly from 56% in 2005, to 70% in 2010. The most marked increase was observed in proximal humerus fractures. Except for 2.3 fractures, CT rates showed similar but less pronounced increases. There is no increase in CT usage and operative management in younger upper limb articular fracture patients. CT utilization is even decreasing in distal radius fractures. Older patients are less likely to get CT scanned but there is a significant increase in operative management of their upper limb articular fractures.
As the population ages, the prevalence of degenerative spinal conditions is estimated to increase. With soaring healthcare costs, we must be vigilant in our accountability for proper resource allocation to ensure universal access. Significant recent increases in lumbar fusion rates have been observed in the US. Less is known regarding the Canadian experience. Our objective was to evaluate recent trends in lumbar fusion and determine how surgeon factors influence reoperation for spinal stenosis (SS) surgery. Longitudinal follow-up study of lumbar surgical procedures for SS using administrative databases. Data was gathered on patient-hospital encounters from April 1, 1995 to December 31, 2001. We analyzed trends in spinal fusion. Index procedures (decompressions or fusions) and surgeon variables, such as specialty (orthopaedics, neurosurgery) and volume (above or below thirty cases/year), were selected as predictors of patient reoperation for SS. Adjustments were made for age, gender, and comorbidity. Reoperation rates were evaluated at six weeks, one and two years and until maximal follow-up. 6128 patients were identified (4200 decompressions and 1928 fusions). Proportionally more fusions were performed over the study period when compared to decompressions (1:2.6 in 1995 versus 1:1.5 in 2001). Orthopaedic specialty and higher surgical volume were associated with increased proportion of fusions (p<
0.0001). Reoperation rate was higher for decompressions at two years (OR 1.4) but not at long-term follow-up to ten years. Surgeon specialty had no impact on reoperation rates. Lower surgical volume demonstrated a higher reoperation rate after adjusting for specialty (Hazard Ratio 1.28). Rates of lumbar spinal fusion have been increasing in Ontario, but at a lesser rate compared with the US. There is wide variation in surgical procedures between surgeon specialty and volume. Surgeon specialty had little impact on reoperation rates. Better long-term survival was observed in spinal surgeons with volumes over thirty cases per year after adjusting for surgeon specialty. Due to increasing rates of spinal fusion, the benefit of improved long-term survival in SS surgery with higher volume surgeons requires more detailed analysis before policy recommendations can be made.
The percentage of patients satisfied with their arthroplasty one-year post-surgery has not improved over the 13 years. (O.A 81%, R.A 87.5% , trauma 63%). The incidence of reoperation (for all causes) in the first year is 1.2% (0.5% infection). The incidence of revision for implant failure appears to be increasing. Outcome data for revision surgery is being collected at present.
Metastatic osteosarcoma is seen in 10-20% of patients at initial presentation with the lung the most common site of metastasis. Historically, prognosis has been poor. We studied trends in survival in our small developed nation and aimed to identify correlations between the survival rate and three factors: newer chemotherapy, advances in radiological imaging and a more aggressive approach adopted by cardiothoracic surgeons for lung metastases. Our national bone tumour registry was used to identify patients at the age of 18 or under, who presented with metastatic disease at initial diagnosis between 1933 and 2006. There were 30 patients identified. Kaplan-Meier analysis was used to determine survival rates and univariate analysis was performed using the Cox regression proportional hazards model. Median survival has improved over the last 50 years; highlighted by the ‘Kotz’ eras demonstrating incremental improvement with more effective chemotherapy agents (p=0.004), and a current 5-year survival of 16%. Aggressive primary and metastatic surgery also show improving trends in survival. Three patients have survived beyond five years. The introduction of computerised tomography scanning has led to an increase in the prevalence of metastases at initial diagnosis. Metastatic osteosarcoma remains with a very poor prognostic factor, however, aggressive management has been shown to prolong survival.

A 5 year review of factors instigating malpractice claims and likely to result in a payout. Possible lessons for the future. During 2002-2007 over 300,000 patients underwent knee arthroplasty (KA) in England and Wales, from which 204 cases of litigation were processed costing in excess of £5million. The complications associated with primary KA are well documented, however those instigating litigation in the UK are not known. This study assessed trends in litigation over the past 5 years identifying instigating factors and success rates to highlight areas for further improvement in patient information and surgical management. Data from the NHS Litigation Authority on claims following KA unrelated to trauma between 2002 and 2007 were obtained and analysed.Background

Dupuytren's disease (DD) is a fibro-proliferative disorder of the palmar fascia whereby a collagen cord contracts affected joints, resulting in flexion deformity that can impair hand function. Currently, surgery is the only effective treatment option in Europe. This 2-part study, consisting of a surgeon survey and chart audit, was designed to assess current surgical practice patterns by DD severity. We report results from the surgeon survey. A total of 687 participants, including 579 orthopedic surgeons (of which 383 were hand specialists) and 108 plastic surgeons, who had been practicing for >3 and <30 years and operated on 5 DD patients between September and December 2008 were surveyed in 12 countries (UK, Germany, France, Italy, Spain, Hungary, Czech Republic, Poland, Netherlands, Sweden, Denmark, Finland). The survey included queries about procedures performed, factors involved in the decision to use a procedure, satisfaction with the procedure, use of physiotherapy, and recurrence.Introduction

Despite a variety of reports to the contrary it was felt by the Christchurch Orthopaedic group that the “wait” on the orthopaedic waiting list has been escalating rapidly to the point that a routine operation is now in the order of approximately 3 years from the time of GP referral. A review of the time taken for GP referrals to be assessed by an Orthopaedic Surgeon was undertaken. The waiting lists from October 98 to May 02 were analysed, in addition to the operation outputs from the Burwood Hospital elective theatre records over the same period. Time taken from referral to be seen, time taken from been placed on the waiting list to receive an operation and volume of elective procedures were evaluated. A breakdown was made of those removed from the list vs those operated on. A major reduction in the waiting list over the last three years was secondary to 1/3 of the people on the list (1177) been “culled”. This was initiated in January 1999 and completed by January 2001. Since January 1999, 2538 patients had received their operations. The waiting list had dropped from 3303 to a low of 1164. It has since climbed to 2036. That waiting longer than 12 months for surgery, initially 64%, had dropped to 29% and has climbed back up to 40%. The figures have climbed dramatically since the waiting list initiative for arthroplasty was discontinued. The culling of the list has been responsible for removal of 1/3 of people off the original list without having an operation and has given a false sense of success in reducing the waiting list to various political interests. The criteria set for culling people assessed as requiring an operation has been set arbitrarily There is twice the number of patients waiting to see an orthopaedic surgeon than 2 years ago of which a proportion are requiring reassessment to be deemed eligible for an operation that they have already been assessed as requiring. The waiting list initiative was effective as an addition to the regular DHB lists in maintaining the lists at a manageable level. Even if all those culled represented a group that no longer required their operation the current list cannot be considered to have such a group as they have all been recently reviewed and are in genuine need. There is an apparent lack of concern and denial over the current escalation in the numbers on the waiting list, and no plan instituted to address it.
The aim was to examine the descriptive epidemiology of Slipped Capital Femoral Epiphysis, with respect to geography and time. We extracted all children with a diagnosis of Slipped Capital Femoral Epiphysis from the Clinical Practice Research Database between 1990 and 2014 (24 years). CPRD is the world's largest database of primary care, which encompasses 8% of the UK population. CPRD was linked to Hospital Episode Statistics, and a validation algorithm applied to maximise sensitivity and specificity of the cases finding methodology. Poisson confidence intervals were calculated, and poison regression used. 596 cases of SCFE were identified. The internal validation algorithm supported a SCFE diagnosis in 88% cases. The age and sex distribution of cases mirrored that in the literature, offering external validity to the cases identified. There was no significant change in the incidence of SCFE over the 24-year study period, with the overall incidence being 4.8 cases per 100,00 0–16 year olds. There was no significant geographic variation in SCFE within the UK. There was a positive association with rising socioeconomic deprivation (p<0.01). There was no seasonal variation in presentation. This study found no evidence to support the common belief that SCFE incidence is increasing, and for the first time demonstrated an association with socioeconomic deprivation. The results are important for considering the feasibility of intervention studies, and offer insights into the disease aetiology.
Of the 120 fractures (in 117 patients), 16 were excluded from our study (10 patients were followed in other institutions and 6 died of non-related causes). From the total of 104 fractures reviewed 77% had been submitted to rigid internal fixation with extramedular devices (95 Blade plates, DCS, Condylar plates, etc) although in the last few years (since 2000) the use of intramedular retrograde nailing has became the standard form of treatment (16 type A and 8 type C, including 2 C3).
In our experience the application of retrograde nails in type A fractures and the combination of multiple screws fixation and retrograde nails in type C fractures provide the best results.
The Trent Arthroplasty Audit Group has been prospectively collecting data on primary knee arthroplasty since 1990 and revision procedures since 1992. Details of 27 000 primary and 1300 revision knee arthroplasties have been registered. In 2001 hospitals in Wales joined the group, increasing the catchment population to 8 million (14% of the UK population). The register has enabled evaluation of changes in the demography and surgical practice of knee arthroplasty in the Trent region over the past 13 years. Over this period there has been a steady increase in the number of arthroplasties registered, from 1330 cases in 1990 to 2855 in 2002. Whilst there has been a slight increase in the proportion of men undergoing surgery, the age distribution remains consistent (mean age 69 years). PFC/Sigma is currently the most commonly used prosthesis in the region. Since 1990 the number of patients registered with rheumatoid arthritis has fallen by almost 50%. During this period there has also been a slight decrease in the proportion of uncemented joints and a decline in the number of bilateral simultaneous procedures taking place. The ratio of primary to revision knee arthroplasty has not changed significantly since 1992 but there is some evidence of specialisation of revision knee surgery. There has been no significant change in patient satisfaction rates since the start of the registry, with 80% of patients reporting that they are satisfied with their joint replacement at 1 year.
Total knee replacement utilisation exceeded total hip replacement rates in the mid-1990s and increased TKR use continues to grow. Considerable provincial area variations exist with regards THR and TKR utilisation in Canada. THR and TKR are more commonly performed in female patients with peak utilisation being between 65 and 74 years of age. One third of THRs and TKRs are now performed on patients <
65 years of age. Average length of stay has dropped precipitously over the last two decades. Average length of stay is now approximately five days for THRs and TKRs. In-hospital mortality is higher for THRs (1.51%) as compared to TKRs (0.54%). Complications leading to readmission are more common in THRs. Age-standardised rates of THR and TKR/100,000 population have increased from 1994–5 to present, but are still lower than other countries. Waiting times for surgery remain a problem with most patients waiting more than six months for surgery. One year post-operatively, 96% of patients would have their primary or revision total hip or knee replacement performed again. Patients are more satisfied with the outcome of primary procedures as compared to revisions. THR patients have a higher level of satisfaction than TKR patients.
Technological advances and economic trends are shaping the future of orthopaedics, where a clinical solution encompasses all phases of surgery. Minimally invasive surgery (MIS) continues to become more popular and important in modern-day orthopaedics, but brings added complexity to the operating room. Computer assisted surgery (CAS) has the potential to provide greater reliability, repeatability, and control to orthopedic surgeries, although limitations in the technologies currently available for minimally invasive CAS procedures leave much to be desired. Despite new techniques and modern technologies, improvements are needed to achieve consistency of optimal patient outcomes in orthopaedic surgery. Healthcare markets are moving to emphasize the value of patient-specific intervention with reliable, custom solutions. We are developing a framework for orthopedic CAS which utilizes new technologies and a cohesive approach in providing a robust solution for the future of orthopaedics. Through the use of surgical preplanning, intra-operative guidance, and post-operative gait analysis, a full analysis and design cycle is used to ensure optimal patient outcome by focusing on the combination of the three surgical phases. In order to realize this comprehensive framework, a system-level design approach combined with cutting-edge technology is needed, catering to patient-specific anatomical reconstruction. In the pre-operative phase, X-ray images are used in the 3-D reconstruction of patient-specific models of the targeted anatomy. This is combined with automated morphometric measurements to provide automatic cutting plane alignment and a complete design suite for patient-specific implants. In the intraoperative phase, new wireless navigation technologies provide robust performance where optical and electromagnetic tracking systems fall short. MEMS capacitive sensor array technology provides accurate and real-time pressure sensing feedback for ligament balancing, and new software frameworks virtualize surgical protocols. Extensive gait analysis including X-ray fluoroscopy provides 3-D kinematic data in the post-operative phase to provide valuable feedback on implant performance for improved implant design.
We examined the risk of thrombotic and major
bleeding events in patients undergoing total hip and knee replacement
(THR and TKR) treated with thromboprophylaxis, using nationwide
population-based databases. We identified 83 756 primary procedures
performed between 1997 and 2011. The outcomes were symptomatic venous thromboembolism
(VTE), myocardial infarction (MI), stroke, death and major bleeding
requiring hospitalisation within 90 days of surgery. A total of 1114 (1.3%) and 483 (0.6%) patients experienced VTE
and bleeding, respectively. The annual risk of VTE varied between
0.9% and 1.6%, and of bleeding between 0.4% and 0.8%. The risk of
VTE and bleeding was unchanged over a 15-year period. A total of
0.7% of patients died within 90 days, with a decrease from 1% in
1997 to 0.6% in 2011 (p <
0.001). A high level of comorbidity
and general anaesthesia were strong risk factors for both VTE and
bleeding, with no difference between THR and TKR patients. The risk
of both MI and stroke was 0.5%, which remained unchanged during
the study period. In this cohort study of patients undergoing THR and TKR patients
in routine clinical practice, approximately 3% experienced VTE,
MI, stroke or bleeding. These risks did not decline during the 15-year
study period, but the risk of dying fell substantially. Cite this article:
The aim of this study was to evaluate temporal trends in the prevalence of primary total hip and knee replacements (THR and TKR) throughout the Trent region from 1991 through 2004. The Trent Regional Arthroplasty Study (TRAS) records details of primary THR and TKR prospectively. TRAS data in conjunction with age-gender population data from the National Office of Statistics was used to quantify the rates of primary THR and TKR as a function of age (45–55, 56–65, 66–75, 76–85 and greater than 85 years), gender and diagnosis (osteoarthritis, rheumatoid arthritis and trauma). Poisson regression analysis was used to evaluate the procedural rate over time in primary THR and TKR as a function of age, gender and diagnosis. A total of 26,281 THR and 23,606 TKR were recorded during this period. The overall prevalence for primary THR did not change significantly over time (IRR = 1.0, 95% CI: 0.99 to 1.0, p = 0.875), whereas, the overall prevalence for primary TKR increased significantly by 2.5% during the fourteen year period (IRR = 1.025, 95% CI: 1.021 to 1.028, p <
0.001). Analysis showed that females had an increased incidence rate ratio (IRR) for both primary THR (IRR = 1.29, 95% CI: 1.26 to 1.33, p <
0.001) and TKR (IRR = 1.17, 95% CI: 1.14 to 1.20, p <
0.001). Patients aged 74–85 years had the largest IRR for both primary THR (IRR = 6.7, 95% CI: 6.4 to 7.0, p <
0.001) and TKR (IRR = 15.3, 95% CI: 14.4 to 16.3, p <
0.001). The prevalence of primary TKR increased significantly over time whereas THR increased steadily in the Trent region between 1991 and 2004. These trends have important ramifications to the number of joint replacements expected to be performed in the future.
Earlier diagnosis is one of the key aims in achieving improved outcomes for patients with cancer. In general, the earlier a tumour is diagnosed, the easier it will be to treat and the greater the chance of cure. We have investigated how tumour size at diagnosis and duration of symptoms, both of which may act as a proxy for delay in diagnosis have varied over a 25 year period and whether there is evidence of improvement. Data were available for 2568 patients with primary bone sarcomas and 2366 with soft tissue sarcomas. The mean size at diagnosis was 10.7 cm for bone tumours and 9.9cm for soft tissue sarcomas. The size of bone sarcomas had not changed with the passage of time but there had been a slight decrease in the size of soft tissue sarcomas (10.3 cm before 2000 vs 9.6cm after 2000, p=0.03). The duration of symptoms reported by patients varied widely with a median of 16 weeks for bone sarcomas and 26 weeks for soft tissue sarcomas. The median duration of symptoms for bone sarcomas had actually increased since 2000 (16 weeks before to 20 weeks after 2000, p⋋0.01), whilst it remained unchanged for soft tissue sarcomas. Further analysis showed that females tended to present with smaller tumours than males and that slower growing tumours (eg. liposarcoma and chondrosarcoma) tended to be larger and have a longer duration of symptoms than other tumours. 15% of patients with a soft tissue sarcoma had undergone a previous inadvertent excision – and this % has not changed over 20 years. Younger patients had smaller soft tissue soft tissue sarcomas than older patients but there was little difference for bone sarcomas. This data shows there is huge room for improvementConclusion
Conventionally, medial malleolus fractures are treated surgically with anatomical reduction and internal fixation using screws. There seems to be no consensus, backed by scientific study on the optimal screw characteristics in the literature. We retrospectively examined case notes and radiographs of 48 consecutive patients taken from our trauma database (21 male, 27 female) with an average age of 50 years (range 16-85) who had undergone medial malleolus fracture fixation with screws at the Royal Free Hospital, London between January 2009 and June 2010. The most commonly used screw was the AO 4.0 mm diameter cancellous partially-threaded screw in 40, 45 and 50 mm lengths (40 mm n = 28, 45 mm n = 26, 50 mm n = 23) with the threads passing beyond the physeal scar in all cases. Incomplete reduction defined as > 1mm fracture displacement was observed on post-operative x-rays in 12 out of 48 cases (25%), all of which relied on partially-threaded screw fixation. In 5 cases where AO 4.0 mm diameter fully-threaded screws engaging the physeal scar had been used, no loss of reduction was observed. This unusual, occasional use of fully-threaded screws prompted us to investigate further using a porcine model and adapted pedo-barographic transducer. We compared pressures generated within the fracture site using AO 4.0 mm partially-threaded cannulated screws, 4.0 mm partially-threaded cancellous screws and 4.0 mm fully-threaded cancellous screws. Fully-threaded cancellous 4.0 mm diameter screws generated almost 3 times the compression of a partially-threaded cancellous screw with superior stability at the fracture. Partially-threaded screws quickly lost purchase, compression and stability particularly when they were cannulated. We also observed that screw thread purchase seemed enhanced in the physeal region. We conclude that fully-threaded cancellous 4.0 mm AO screws are superior to longer partially-threaded screws and that use of cannulated 4.0 mm partially-threaded screws should be avoided in fixation of medial malleolus fractures.
The Oxford knee score (OKS) is a validated and
widely accepted disease-specific patient-reported outcome measure,
but there is limited evidence regarding any long-term trends in
the score. We reviewed 5600 individual OKS questionnaires (1547
patients) from a prospectively-collected knee replacement database,
to determine the trends in OKS over a ten-year period following
total knee replacement. The mean OKS pre-operatively was 19.5 (95%
confidence interval (CI) 18.8 to 20.2). The maximum post-operative
OKS was observed at two years (mean score 34.4 (95% CI 33.7 to 35.2)),
following which a gradual but significant decline was observed through
to the ten-year assessment (mean score 30.1 (95% CI 29.1 to 31.1))
(p <
0.001). A similar trend was observed for most of the individual
OKS components (p <
0.001). Kneeling ability initially improved
in the first year but was then followed by rapid deterioration (p
<
0.001). Pain severity exhibited the greatest improvement, although
residual pain was reported in over two-thirds of patients post-operatively,
and peak improvement in the night pain component did not occur until
year four. Post-operative OKS was lower for women (p <
0.001),
those aged <
60 years (p <
0.003) and those with a body mass
index >
35 kg/m2 (p <
0.014), although similar changes
in scores were observed. This information may assist surgeons in
advising patients of their expected outcomes, as well as providing
a comparative benchmark for evaluating longer-term outcomes following
knee replacement. Cite this article:
Increasing numbers of posterior lumbar fusions
are being performed. The purpose of this study was to identify trends
in demographics, mortality and major complications in patients undergoing
primary posterior lumbar fusion. We accessed data collected for
the Nationwide Inpatient Sample for each year between 1998 and 2008
and analysed trends in the number of lumbar fusions, mean patient
age, comorbidity burden, length of hospital stay, discharge status,
major peri-operative complications and mortality. An estimated 1 288 496
primary posterior lumbar fusion operations were performed between
1998 and 2008 in the United States. The total number of procedures,
mean patient age and comorbidity burden increased over time. Hospital
length of stay decreased, although the in-hospital mortality (adjusted
and unadjusted for changes in length of hospital stay) remained
stable. However, a significant increase was observed in peri-operative
septic, pulmonary and cardiac complications. Although in-hospital mortality
rates did not change over time in the setting of increases in mean
patient age and comorbidity burden, some major peri-operative complications
increased. These trends highlight the need for appropriate peri-operative services
to optimise outcomes in an increasingly morbid and older population
of patients undergoing lumbar fusion.
NICE published the guidelines ‘Selection of prostheses for primary hip replacement’ in 2000. Essentially these guidelines made two recommendations: firstly to use prostheses which had attained the ‘10 year benchmark’ of a revision rate of 10% or less at 10 years, or had a minimum of three years revision rate experience that was on target to reach this benchmark; and secondly to use cemented hip prostheses to the exclusion of uncemented and hybrid prostheses. The information from the Trent Regional Arthroplasty Study (TRAS) has been used to retrospectively examine the types of hip prostheses used from 1990 – 2005, and assess the impact that the NICE guidelines have had on orthopaedic practice. This study revealed that the percentage of prostheses used which attained the ‘ten year benchmark’ has increased since the guidelines were published. In 2001, of the ten cups, which constituted 80% of the acetabular components used, only three attained this NICE benchmark, but by 2005 this number had risen to eight. Similarly in 2001, of the eight stems, which constituted almost 80% of the femoral components used, only five attained this NICE benchmark. In 2005 seven out of these eight stems had attained the minimum standard. However contrary to the recommendation made by NICE in 2000, to use cemented prostheses, the results indicate the use of uncemented prostheses has trebled (from 6.7% to 19.2%, n= 137 and 632 respectively), and the use of hybrid prostheses has more than doubled (from 8.8% to 22% of all prostheses, n= 181 and 722 respectively) since the guidelines were published. Therefore the recommendations made by NICE are not being followed, which calls the value of NICE guidelines into question.

Aims. The purpose of this study was to assess total knee arthroplasty (TKA) volume and rates of early complications in morbidly obese patients over the last decade, where the introduction of quality models influencing perioperative care pathways occurred. Methods. Patients undergoing TKA between 2011 to 2018 were identified in the American College of Surgeons National Surgical Quality Improvement Program database. Patients were stratified by BMI < 40 kg/m. 2. and ≥ 40 kg/m. 2. and evaluated by the number of cases per year. The 30-day rates of any complication, wound complications, readmissions, and reoperation were assessed.
Excessive opioid prescriptions after total joint arthroplasty (TJA) increase risks for adverse opioid related events, chronic opioid use, and increase the availability of opioids for unlawful diversion. Thus, decreasing postoperative prescriptions may improve quality after TJA. Concerns exist that a decrease in opioids prescribed may increase complications such as readmissions, emergency department (ED) visits or worsened patient reported outcomes (PROs). The purpose of this quality improvement study was to explore whether a reduction in opioids prescribed after TJA resulted in increased complications. Methods: Data originated from a statewide arthroplasty database (MARCQI). The database collects over 96% of all TJA performed in the state of Michigan, USA. Data was prospectively abstracted and included OMEs prescribed at discharge, readmissions, ED visits within 30 days and PROs. Data was collected one year before and after the creation of an opioid prescribing protocol that had decreased prescriptions by approximately 50% in opioid naive and tolerant patients.
Pelvic discontinuity (PD) is a detrimental complication following total hip arthroplasty (THA). The aim of this study was to assess the clinical and radiological results of patients with PD who were revised using a custom-made triflange acetabular component (CTAC). This is a single centre prospective study of patients with PD following THA who were treated with a CTAC. The Hip Disability and Osteoarthritis Outcome Score (HOOS), modified Oxford Hip Score (mOHS), EurQol five-dimension three-level (EQ-5D-3L) utility, and Numeric Rating Scale (NRS), including visual analogue score (VAS) for pain, were gathered at baseline, and at one- and two-year follow-up. Clinical and radiological complications, including reasons for revisions were registered.
